Conformément à la suggestion de Nick Perkins ,j'ai dûfusionner deux requêtes comme ceci:

 $q1 = get_posts(array(
        'fields' => 'ids',
        'post_type' => 'post',
        's' => $query
));

$q2 = get_posts(array(
        'fields' => 'ids',
        'post_type' => 'post',
        'meta_query' => array(
            array(
               'key' => 'speel',
               'value' => $query,
               'compare' => 'LIKE'
            )
         )
));

$unique = array_unique( array_merge( $q1, $q2 ) );

$posts = get_posts(array(
    'post_type' => 'posts',
    'post__in' => $unique,
    'post_status' => 'publish',
    'posts_per_page' => -1
));

if( $posts ) : foreach( $posts as $post ) :
     setup_postdata($post);

     // now use standard loop functions like the_title() etc.     

enforeach; endif;
 

As per Nick Perkins' suggestion, I had to merge two queries like so:

$q1 = get_posts(array(
        'fields' => 'ids',
        'post_type' => 'post',
        's' => $query
));

$q2 = get_posts(array(
        'fields' => 'ids',
        'post_type' => 'post',
        'meta_query' => array(
            array(
               'key' => 'speel',
               'value' => $query,
               'compare' => 'LIKE'
            )
         )
));

$unique = array_unique( array_merge( $q1, $q2 ) );

$posts = get_posts(array(
    'post_type' => 'posts',
    'post__in' => $unique,
    'post_status' => 'publish',
    'posts_per_page' => -1
));

if( $posts ) : foreach( $posts as $post ) :
     setup_postdata($post);

     // now use standard loop functions like the_title() etc.     

enforeach; endif;

Je cherche depuis des heures une solution à ceproblème. Lafusion detableauxn'estpas la voie à suivre,en particulier lorsque les requêtes sont complexeset que vous devezpouvoir ajouter desméta-requêtes à l'avenir. La solution quiest simplistebelle est de changer le "s" à celui quipermet à lafois de rechercher destitreset desméta-champs.

 add_action( 'pre_get_posts', function( $q )
{
    if( $title = $q->get( '_meta_or_title' ) )
    {
        add_filter( 'get_meta_sql', function( $sql ) use ( $title )
        {
            global $wpdb;

            // Only run once:
            static $nr = 0; 
            if( 0 != $nr++ ) return $sql;

            // Modified WHERE
            $sql['where'] = sprintf(
                " AND ( %s OR %s ) ",
                $wpdb->prepare( "{$wpdb->posts}.post_title like '%%%s%%'", $title),
                mb_substr( $sql['where'], 5, mb_strlen( $sql['where'] ) )
            );

            return $sql;
        });
    }
});
 

Utilisation:

 $meta_query = array();
$args = array();
$search_string = "test";

$meta_query[] = array(
    'key' => 'staff_name',
    'value' => $search_string,
    'compare' => 'LIKE'
);
$meta_query[] = array(
    'key' => 'staff_email',
    'value' => $search_string,
    'compare' => 'LIKE'
);

//if there is more than one meta query 'or' them
if(count($meta_query) > 1) {
    $meta_query['relation'] = 'OR';
}

// The Query
$args['post_type'] = "staff";
$args['_meta_or_title'] = $search_string; //not using 's' anymore
$args['meta_query'] = $meta_query;



$the_query = new WP_Query($args)
 

I have been searching for hours for a solution to this problem. Array merging is not the way to go, especially when the queries are complex and you must be able to add to meta queries in the future. The solution which is simplistically beautiful is to change 's' to one which allows both searching titles and meta fields.

add_action( 'pre_get_posts', function( $q )
{
    if( $title = $q->get( '_meta_or_title' ) )
    {
        add_filter( 'get_meta_sql', function( $sql ) use ( $title )
        {
            global $wpdb;

            // Only run once:
            static $nr = 0; 
            if( 0 != $nr++ ) return $sql;

            // Modified WHERE
            $sql['where'] = sprintf(
                " AND ( %s OR %s ) ",
                $wpdb->prepare( "{$wpdb->posts}.post_title like '%%%s%%'", $title),
                mb_substr( $sql['where'], 5, mb_strlen( $sql['where'] ) )
            );

            return $sql;
        });
    }
});

Usage:

$meta_query = array();
$args = array();
$search_string = "test";

$meta_query[] = array(
    'key' => 'staff_name',
    'value' => $search_string,
    'compare' => 'LIKE'
);
$meta_query[] = array(
    'key' => 'staff_email',
    'value' => $search_string,
    'compare' => 'LIKE'
);

//if there is more than one meta query 'or' them
if(count($meta_query) > 1) {
    $meta_query['relation'] = 'OR';
}

// The Query
$args['post_type'] = "staff";
$args['_meta_or_title'] = $search_string; //not using 's' anymore
$args['meta_query'] = $meta_query;



$the_query = new WP_Query($args)

Beaucoup de codepeut être réduiten utilisant une versionmodifiée de cette réponse .

 $q1 = new WP_Query( array(
    'post_type' => 'post',
    'posts_per_page' => -1,
    's' => $query
));

$q2 = new WP_Query( array(
    'post_type' => 'post',
    'posts_per_page' => -1,
    'meta_query' => array(
        array(
           'key' => 'speel',
           'value' => $query,
           'compare' => 'LIKE'
        )
     )
));

$result = new WP_Query();
$result->posts = array_unique( array_merge( $q1->posts, $q2->posts ), SORT_REGULAR );
$result->post_count = count( $result->posts );
 

A lot of code can be reduced by using a modified version of this answer.

$q1 = new WP_Query( array(
    'post_type' => 'post',
    'posts_per_page' => -1,
    's' => $query
));

$q2 = new WP_Query( array(
    'post_type' => 'post',
    'posts_per_page' => -1,
    'meta_query' => array(
        array(
           'key' => 'speel',
           'value' => $query,
           'compare' => 'LIKE'
        )
     )
));

$result = new WP_Query();
$result->posts = array_unique( array_merge( $q1->posts, $q2->posts ), SORT_REGULAR );
$result->post_count = count( $result->posts );

J'aieu lemêmeproblème,pourmonnouveau site,je viens d'ajouter unnouveauméta & quot;titre & quot;:

functions.php

 add_action('save_post', 'title_to_meta');

function title_to_meta($post_id)
{
    update_post_meta($post_id, 'title', get_the_title($post_id)); 
}
 

Etpuis… ajoutez simplement quelque chose comme ça:

 $sub = array('relation' => 'OR');

$sub[] = array(
    'key'     => 'tags',
    'value'   => $_POST['q'],
    'compare' => 'LIKE',
);

$sub[] = array(
    'key'     => 'description',
    'value'   => $_POST['q'],
    'compare' => 'LIKE',
);

$sub[] = array(
    'key'     => 'title',
    'value'   => $_POST['q'],
    'compare' => 'LIKE',
);

$params['meta_query'] = $sub;
 

Quepensez-vous de cette solution de contournement?

i had the same problem, for my new site i just added a new meta "title" :

functions.php

add_action('save_post', 'title_to_meta');

function title_to_meta($post_id)
{
    update_post_meta($post_id, 'title', get_the_title($post_id)); 
}

And then.. just add something like that :

$sub = array('relation' => 'OR');

$sub[] = array(
    'key'     => 'tags',
    'value'   => $_POST['q'],
    'compare' => 'LIKE',
);

$sub[] = array(
    'key'     => 'description',
    'value'   => $_POST['q'],
    'compare' => 'LIKE',
);

$sub[] = array(
    'key'     => 'title',
    'value'   => $_POST['q'],
    'compare' => 'LIKE',
);

$params['meta_query'] = $sub;

What do you think about this workaround ?

J'ai unpeu optimisé la réponse @Stabir Kira

 function wp78649_extend_search( $query ) {
    $search_term = filter_input( INPUT_GET, 's', FILTER_SANITIZE_NUMBER_INT) ?: 0;
    if (

        && !is_admin()
        && $query->is_main_query()
        && //your extra condition
    ) {
        $query->set('meta_query', [

I have optimized @Stabir Kira answer a bit

function wp78649_extend_search( $query ) {
    $search_term = filter_input( INPUT_GET, 's', FILTER_SANITIZE_NUMBER_INT) ?: 0;
    if (
        $query->is_search
        && !is_admin()
        && $query->is_main_query()
        && //your extra condition
    ) {
        $query->set('meta_query', [
            [
                'key' => 'meta_key',
                'value' => $search_term,
                'compare' => '='
            ]
        ]);

        add_filter( 'get_meta_sql', function( $sql )
        {
            global $wpdb;

            static $nr = 0;
            if( 0 != $nr++ ) return $sql;

            $sql['where'] = mb_eregi_replace( '^ AND', ' OR', $sql['where']);

            return $sql;
        });
    }
    return $query;
}
add_action( 'pre_get_posts', 'wp78649_extend_search');

Now you can search by (title, content, excrept) or (meta field) or (both of them).

Ehbien,c'est une sorte de hackmais çamarche. Vous devez ajouter unfiltreposts_clauses. Cettefonction defiltrage vérifie que l'un desmots de requêteexiste dans le champpersonnalisé "speel"et la requête restante resteintacte.

 function custom_search_where($pieces) {

    // filter for your query
    if (is_search() && !is_admin()) {

        global $wpdb;

        $keywords = explode(' ', get_query_var('s'));
        $query = "";
        foreach ($keywords as $word) {

            // skip possible adverbs and numbers
            if (is_numeric($word) || strlen($word) <= 2) 
                continue;

            $query .= "((mypm1.meta_key = 'speel')";
            $query .= " AND (mypm1.meta_value  LIKE '%{$word}%')) OR ";
        }

        if (!empty($query)) {
            // add to where clause
            $pieces['where'] = str_replace("(((wp_posts.post_title LIKE '%", "( {$query} ((wp_posts.post_title LIKE '%", $pieces['where']);

            $pieces['join'] = $pieces['join'] . " INNER JOIN {$wpdb->postmeta} AS mypm1 ON ({$wpdb->posts}.ID = mypm1.post_id)";
        }
    }
    return ($pieces);
}
add_filter('posts_clauses', 'custom_search_where', 20, 1);
 

Well its kind of a hack but it works. You need to add posts_clauses filter. This filter function check for the any of the query word exists in the custom field "speel" and the remaining query stays intact.

function custom_search_where($pieces) {

    // filter for your query
    if (is_search() && !is_admin()) {

        global $wpdb;

        $keywords = explode(' ', get_query_var('s'));
        $query = "";
        foreach ($keywords as $word) {

            // skip possible adverbs and numbers
            if (is_numeric($word) || strlen($word) <= 2) 
                continue;

            $query .= "((mypm1.meta_key = 'speel')";
            $query .= " AND (mypm1.meta_value  LIKE '%{$word}%')) OR ";
        }

        if (!empty($query)) {
            // add to where clause
            $pieces['where'] = str_replace("(((wp_posts.post_title LIKE '%", "( {$query} ((wp_posts.post_title LIKE '%", $pieces['where']);

            $pieces['join'] = $pieces['join'] . " INNER JOIN {$wpdb->postmeta} AS mypm1 ON ({$wpdb->posts}.ID = mypm1.post_id)";
        }
    }
    return ($pieces);
}
add_filter('posts_clauses', 'custom_search_where', 20, 1);

Toutes les solutions ci-dessusne renvoient des résultats que si une correspondanceexiste dans la cléméta speel.Si vous avez des résultats ailleursmaispas dans ce domaine,vousn'obtiendrez rien.Personnene veut ça.

Unejointure àgaucheestnécessaire.Ce qui suit vaen créer un.

            $meta_query_args = array(
              'relation' => 'OR',
              array(
                'key' => 'speel',
                'value' => $search_term,
                'compare' => 'LIKE',
              ),
              array(
                'key' => 'speel',
                'compare' => 'NOT EXISTS',
              ),
            );
            $query->set('meta_query', $meta_query_args);
 

All of the above solutions only return results if a match exists in the speel meta key. If you have results elsewhere but not in this field you'll get nothing. Nobody wants that.

A left join is needed. The following will create one.

           $meta_query_args = array(
              'relation' => 'OR',
              array(
                'key' => 'speel',
                'value' => $search_term,
                'compare' => 'LIKE',
              ),
              array(
                'key' => 'speel',
                'compare' => 'NOT EXISTS',
              ),
            );
            $query->set('meta_query', $meta_query_args);

pourmoifonctionneparfaitement le code suivant:

             $search_word = $_GET['id'];
        $data['words'] = trim(urldecode($search_word));

        $q1 = new WP_Query( array(
            'post_type' => array('notas', 'productos'),
            'posts_per_page' => -1,
            's' => $search_word
        ));

        $q2 = new WP_Query( array(
            'post_type' => array('notas', 'productos'),
            'posts_per_page' => -1,
            'meta_query' => array(
                'relation' => 'OR',
                array(
                   'key'   => 'subtitulo',
                    'value' => $search_word,
                    'compare' => 'LIKE'
                ),
                array(
                    'key'   => 'thumbnail_bajada',
                    'value' => $search_word,
                    'compare' => 'LIKE'
                )
             )
        ));

        $result = new WP_Query();
        $result->posts = array_unique( array_merge( $q1->posts, $q2->posts ), SORT_REGULAR );
        $result->post_count = count( $result->posts );
 

for me works perfect the next code:

            $search_word = $_GET['id'];
        $data['words'] = trim(urldecode($search_word));

        $q1 = new WP_Query( array(
            'post_type' => array('notas', 'productos'),
            'posts_per_page' => -1,
            's' => $search_word
        ));

        $q2 = new WP_Query( array(
            'post_type' => array('notas', 'productos'),
            'posts_per_page' => -1,
            'meta_query' => array(
                'relation' => 'OR',
                array(
                   'key'   => 'subtitulo',
                    'value' => $search_word,
                    'compare' => 'LIKE'
                ),
                array(
                    'key'   => 'thumbnail_bajada',
                    'value' => $search_word,
                    'compare' => 'LIKE'
                )
             )
        ));

        $result = new WP_Query();
        $result->posts = array_unique( array_merge( $q1->posts, $q2->posts ), SORT_REGULAR );
        $result->post_count = count( $result->posts );

C'est uneexcellente solution,mais vous devez corriger une chose. Lorsque vous appelez 'post__in',vous devez définir untableau d'identifiantset $ uniqueest untableau d'articles.

exemple:

 $q1 = get_posts(array(
        'fields' => 'ids',
        'post_type' => 'post',
        's' => $query
));

$q2 = get_posts(array(
        'fields' => 'ids',
        'post_type' => 'post',
        'meta_query' => array(
            array(
               'key' => 'speel',
               'value' => $query,
               'compare' => 'LIKE'
            )
         )
));

$unique = array_unique( array_merge( $q1->posts, $q2->posts ) );

$array = array(); //here you initialize your array

foreach($posts as $post)
{
    $array[] = $post->ID; //fill the array with post ID
}


$posts = get_posts(array(
    'post_type' => 'posts',
    'post__in' => $array,
    'post_status' => 'publish',
    'posts_per_page' => -1
));
 

This is a great solution but you need to fix one thing. When you call 'post__in' you need to set an array of ids and $unique is an array of posts.

example:

$q1 = get_posts(array(
        'fields' => 'ids',
        'post_type' => 'post',
        's' => $query
));

$q2 = get_posts(array(
        'fields' => 'ids',
        'post_type' => 'post',
        'meta_query' => array(
            array(
               'key' => 'speel',
               'value' => $query,
               'compare' => 'LIKE'
            )
         )
));

$unique = array_unique( array_merge( $q1->posts, $q2->posts ) );

$array = array(); //here you initialize your array

foreach($posts as $post)

La réponse @ satbir-kirafonctionnetrèsbien maisellene recherchera que dans lamétaet letitre dumessage. Si vous souhaitez qu'il recherche dans lesméta,lestitreset le contenu,voici la versionmodifiée.

     add_action( 'pre_get_posts', function( $q )
    {
      if( $title = $q->get( '_meta_or_title' ) )
      {
        add_filter( 'get_meta_sql', function( $sql ) use ( $title )
        {
          global $wpdb;

          // Only run once:
          static $nr = 0;
          if( 0 != $nr++ ) return $sql;

          // Modified WHERE
          $sql['where'] = sprintf(
              " AND ( (%s OR %s) OR %s ) ",
              $wpdb->prepare( "{$wpdb->posts}.post_title like '%%%s%%'", $title),
              $wpdb->prepare( "{$wpdb->posts}.post_content like '%%%s%%'", $title),
              mb_substr( $sql['where'], 5, mb_strlen( $sql['where'] ) )
          );

          return $sql;
        });
      }
    });
 

Et voici son utilisation:

 $args['_meta_or_title'] = $get['search']; //not using 's' anymore

$args['meta_query'] = array(
  'relation' => 'OR',
  array(
    'key' => '_ltc_org_name',
    'value' => $get['search'],
    'compare' => 'LIKE'
  ),
  array(
    'key' => '_ltc_org_school',
    'value' => $get['search'],
    'compare' => 'LIKE'
  ),
  array(
    'key' => '_ltc_district_address',
    'value' => $get['search'],
    'compare' => 'LIKE'
  )
);
 

Remplacez $get['search']par votre valeur de recherche

@satbir-kira answer works great but it will only search through the meta and post title. If you want it to search through meta, title and content, here is the modified version.

    add_action( 'pre_get_posts', function( $q )
    {
      if( $title = $q->get( '_meta_or_title' ) )
      {
        add_filter( 'get_meta_sql', function( $sql ) use ( $title )
        {
          global $wpdb;

          // Only run once:
          static $nr = 0;
          if( 0 != $nr++ ) return $sql;

          // Modified WHERE
          $sql['where'] = sprintf(
              " AND ( (%s OR %s) OR %s ) ",
              $wpdb->prepare( "{$wpdb->posts}.post_title like '%%%s%%'", $title),
              $wpdb->prepare( "{$wpdb->posts}.post_content like '%%%s%%'", $title),
              mb_substr( $sql['where'], 5, mb_strlen( $sql['where'] ) )
          );

          return $sql;
        });
      }
    });

And here is it's usage:

$args['_meta_or_title'] = $get['search']; //not using 's' anymore

$args['meta_query'] = array(
  'relation' => 'OR',
  array(
    'key' => '_ltc_org_name',
    'value' => $get['search'],
    'compare' => 'LIKE'
  ),
  array(
    'key' => '_ltc_org_school',
    'value' => $get['search'],
    'compare' => 'LIKE'
  ),
  array(
    'key' => '_ltc_district_address',
    'value' => $get['search'],
    'compare' => 'LIKE'
  )
);

Replace $get['search'] with your search value

Voici une autrefaçon,changez simplement la demande avec lefiltre 'posts_where_request'. Tout seratoujours la valeurpar défaut sauf ('s' AND 'meta_query')=> ('s' OR 'meta_query').

 AND ( ((posts.post_title LIKE 'Lily') OR (posts.post_excerpt LIKE 'Lily') OR (posts.post_content LIKE 'Lily')) )
AND ( ( postmeta.meta_key = 'author' AND postmeta.meta_value LIKE 'Lily' ) )

=>

AND ( 
    ( ( postmeta.meta_key = 'author' AND postmeta.meta_value LIKE 'Lily' ) )
    OR
    ((posts.post_title LIKE 'Lily') OR (posts.post_excerpt LIKE 'Lily') OR (posts.post_content LIKE 'Lily'))
)
 

voici le code

 function edit_request_wp_query( $where ) {
    global $wpdb;
    if ( strpos($where, $wpdb->postmeta.'.meta_key') && strpos($where, $wpdb->posts.'.post_title') ) {
        $string = $where;
        $index_meta = index_argument_in_request($string, $wpdb->postmeta.'.meta_key', $wpdb->postmeta.'.meta_value');
        $meta_query = substr($string, $index_meta['start'], $index_meta['end']-$index_meta['start']);
        $string = str_replace( $meta_query, '', $string );

        $meta_query = ltrim($meta_query, 'AND').' OR '; 
        $index_s = index_argument_in_request($string, $wpdb->posts.'.post_title');
        $insert_to = strpos($string, '(', $index_s['start'])+1;
        $string = substr_replace($string, $meta_query, $insert_to, 0);

        $where = $string;
    }
    return $where;
}
add_filter('posts_where_request', 'edit_request_wp_query');

function index_argument_in_request($string, $key_start, $key_end = '') {
    if (!$key_end) $key_end = $key_start;
    $index_key_start = strpos($string, $key_start);
    $string_before = substr($string, 0, $index_key_start);
    $index_start = strrpos($string_before, 'AND');

    $last_index_key = strrpos($string, $key_end);
    $index_end = strpos($string, 'AND', $last_index_key);

    return ['start' => $index_start, 'end' => $index_end];
}
 

Here's another way, just change the request with the 'posts_where_request' filter. Everything will still be the default except ('s' AND 'meta_query') => ('s' OR 'meta_query').

AND ( ((posts.post_title LIKE 'Lily') OR (posts.post_excerpt LIKE 'Lily') OR (posts.post_content LIKE 'Lily')) )
AND ( ( postmeta.meta_key = 'author' AND postmeta.meta_value LIKE 'Lily' ) )

=>

AND ( 
    ( ( postmeta.meta_key = 'author' AND postmeta.meta_value LIKE 'Lily' ) )
    OR
    ((posts.post_title LIKE 'Lily') OR (posts.post_excerpt LIKE 'Lily') OR (posts.post_content LIKE 'Lily'))
)

this is the code

function edit_request_wp_query( $where ) {
    global $wpdb;
    if ( strpos($where, $wpdb->postmeta.'.meta_key') && strpos($where, $wpdb->posts.'.post_title') ) {
        $string = $where;
        $index_meta = index_argument_in_request($string, $wpdb->postmeta.'.meta_key', $wpdb->postmeta.'.meta_value');
        $meta_query = substr($string, $index_meta['start'], $index_meta['end']-$index_meta['start']);
        $string = str_replace( $meta_query, '', $string );

        $meta_query = ltrim($meta_query, 'AND').' OR '; 
        $index_s = index_argument_in_request($string, $wpdb->posts.'.post_title');
        $insert_to = strpos($string, '(', $index_s['start'])+1;
        $string = substr_replace($string, $meta_query, $insert_to, 0);

        $where = $string;
    }
    return $where;
}
add_filter('posts_where_request', 'edit_request_wp_query');

function index_argument_in_request($string, $key_start, $key_end = '') {
    if (!$key_end) $key_end = $key_start;
    $index_key_start = strpos($string, $key_start);
    $string_before = substr($string, 0, $index_key_start);
    $index_start = strrpos($string_before, 'AND');

    $last_index_key = strrpos($string, $key_end);
    $index_end = strpos($string, 'AND', $last_index_key);

    return ['start' => $index_start, 'end' => $index_end];
}
