comment interroger les articles par catégorie et tag?

Modifier: voir ci-dessous lamanière appropriée d'interroger les catégorieset lesintersections debalises.

 global $wp_query;
        $args = array(
        'category__and' => 'category', //must use category id for this field
        'tag__in' => 'post_tag', //must use tag id for this field
        'posts_per_page' => -1); //get all posts

$posts = get_posts($args);
        foreach ($posts as $post) :
  //do stuff 
     endforeach;
 

Edit: See below for proper way to query category and tag intersections.

global $wp_query;
        $args = array(
        'category__and' => 'category', //must use category id for this field
        'tag__in' => 'post_tag', //must use tag id for this field
        'posts_per_page' => -1); //get all posts

$posts = get_posts($args);
        foreach ($posts as $post) :
  //do stuff 
     endforeach;

Jepense que c'est unbogue dans WordPress qui a été commenté ailleurs,essayez d'utiliser lenom de labaliseplutôt que l'ID alors cela devraitfonctionner:

 $args = array(
    'posts_per_page' => 3,
    'tag' => 'review',
    'cat' => 9,
);
query_posts($args);
 

Dites-nous comment vous vousen sortez,sans savoir ce qui sepasse avec lesbalises avecplusieursmots dans lenom.

I think this is bug in WordPress that has been commented on elsewhere, try using the name of the tag rather than the ID then it should work:

$args = array(
    'posts_per_page' => 3,
    'tag' => 'review',
    'cat' => 9,
);
query_posts($args);

Let us know how you get on, not sure what happens with tags with multiple words in the name.

Je suistombé sur cemêmeproblèmeet je l'ai résoluen faisant une requête MySQL.

en bref: get_post ($ args) vous renverra les articles qui ont la catégorie=MaCatégorie OU labalise=MonTag.

ce que vous voulez,c'est changer votre OU en ET .

ma logique était d'aller directement avec une requête MySQL:

• Requête 1=Sélectionneztous les articles qui ont la catégorie MyCat
• Requête 2=Sélectionneztous lesmessages qui ont labalise MyTag
• Enfin: sélectionneztous lesmessages qui sont dans la requête 1 ET la requête 2.

J'ai utilisé wpdb au lieu de query_post ();

Unpeu de code (retour des articlespubliés avec la catégorie MyCatet labalise MyTag) :

     $query_byTag="
            SELECT wp_posts.ID
            FROM wp_posts, wp_term_relationships, wp_terms
            WHERE wp_posts.ID = wp_term_relationships.object_id
            AND wp_terms.term_id = wp_term_relationships.term_taxonomy_id
            AND wp_terms.name = 'MyTag'";

    $query_byCat="
            SELECT wp_posts.ID
            FROM wp_posts, wp_term_relationships, wp_terms
            WHERE wp_posts.ID = wp_term_relationships.object_id
            AND wp_terms.term_id = wp_term_relationships.term_taxonomy_id
            AND wp_terms.name = 'MyCat'";

$query ="
            SELECT      wp_posts.post_title AS title , 
                        wp_posts.post_content AS content,
                        wp_posts.post_date AS blogdate 
            FROM wp_posts
            WHERE wp_posts.post_status = 'publish'
            AND wp_posts.ID IN (".$query_byTag.")
            AND wp_posts.ID IN (".$query_byCat.")
            ORDER BY wp_posts.post_date DESC ";

$result= $wpdb->get_results($query);
 

C'est unemauvaisefaçon de lefairemaisj'espère que ça aide=)

I stumbled into this same issue and resolved it by making a MySQL request .

in short : get_post($args) will return you posts who have the category=MyCategory OR the tag=MyTag.

what you want is to change your OR to AND .

my logic was to go straight with a MySQL Query:

• Query 1 = Select all the posts who has the category MyCat
• Query 2 = Select all the posts who has the tag MyTag
• FinalLY : Select all the posts who are in Query 1 AND Query 2 .

I used wpdb instead of query_post();

A bit of code (returning published posts with category MyCat and tag MyTag ):

    $query_byTag="
            SELECT wp_posts.ID
            FROM wp_posts, wp_term_relationships, wp_terms
            WHERE wp_posts.ID = wp_term_relationships.object_id
            AND wp_terms.term_id = wp_term_relationships.term_taxonomy_id
            AND wp_terms.name = 'MyTag'";

    $query_byCat="
            SELECT wp_posts.ID
            FROM wp_posts, wp_term_relationships, wp_terms
            WHERE wp_posts.ID = wp_term_relationships.object_id
            AND wp_terms.term_id = wp_term_relationships.term_taxonomy_id
            AND wp_terms.name = 'MyCat'";

$query ="
            SELECT      wp_posts.post_title AS title , 
                        wp_posts.post_content AS content,
                        wp_posts.post_date AS blogdate 
            FROM wp_posts
            WHERE wp_posts.post_status = 'publish'
            AND wp_posts.ID IN (".$query_byTag.")
            AND wp_posts.ID IN (".$query_byCat.")
            ORDER BY wp_posts.post_date DESC ";

$result= $wpdb->get_results($query);

This is a dirty way to do it but I hope it helps =)

Ce codefonctionne:

 $args = array(
    'tag' => get_queried_object()->slug, // If permalink like example.com/tag/example-tag, etc.
    'posts_per_page' => -1,
    'tax_query' => array( 
        array(
            'taxonomy' => 'category', // Taxonomy, in my case I need default post categories
            'field'    => 'slug',
            'terms'    => 'interior', // Your category slug (I have a category 'interior')
        ),
        ) 
); // Get all posts
$posts_new = get_posts( $args );
 

This code works:

$args = array(
    'tag' => get_queried_object()->slug, // If permalink like example.com/tag/example-tag, etc.
    'posts_per_page' => -1,
    'tax_query' => array( 
        array(
            'taxonomy' => 'category', // Taxonomy, in my case I need default post categories
            'field'    => 'slug',
            'terms'    => 'interior', // Your category slug (I have a category 'interior')
        ),
        ) 
); // Get all posts
$posts_new = get_posts( $args );

 SELECT wp_posts.post_name
FROM wp_posts, wp_term_relationships, wp_terms, wp_term_taxonomy
WHERE wp_posts.ID = wp_term_relationships.object_id
AND wp_terms.term_id = wp_term_taxonomy.term_id
AND wp_term_taxonomy.term_taxonomy_id = wp_term_relationships.term_taxonomy_id
AND wp_terms.name = "MY TAG"
 

SELECT wp_posts.post_name
FROM wp_posts, wp_term_relationships, wp_terms, wp_term_taxonomy
WHERE wp_posts.ID = wp_term_relationships.object_id
AND wp_terms.term_id = wp_term_taxonomy.term_id
AND wp_term_taxonomy.term_taxonomy_id = wp_term_relationships.term_taxonomy_id
AND wp_terms.name = "MY TAG"
