Comment obtenir un identifiant de publication (page ou CPT) à partir d'un titre ou d'un slug?

vouspouvez utiliser cettefonction qui sautepargoogle "obtenir l'articlepartitre"

 /**
* Retrieve a post given its title.
*
* @uses $wpdb
*
* @param string $post_title Page title
* @param string $post_type post type ('post','page','any custom type')
* @param string $output Optional. Output type. OBJECT, ARRAY_N, or ARRAY_A.
* @return mixed
*/
function get_post_by_title($page_title, $post_type ='post' , $output = OBJECT) {
    global $wpdb;
        $post = $wpdb->get_var( $wpdb->prepare( "SELECT ID FROM $wpdb->posts WHERE post_title = %s AND post_type= %s", $page_title, $post_type));
        if ( $post )
            return get_post($post, $output);

    return null;
}
 

you can use this function that jumps by google "get post by title"

/**
* Retrieve a post given its title.
*
* @uses $wpdb
*
* @param string $post_title Page title
* @param string $post_type post type ('post','page','any custom type')
* @param string $output Optional. Output type. OBJECT, ARRAY_N, or ARRAY_A.
* @return mixed
*/
function get_post_by_title($page_title, $post_type ='post' , $output = OBJECT) {
    global $wpdb;
        $post = $wpdb->get_var( $wpdb->prepare( "SELECT ID FROM $wpdb->posts WHERE post_title = %s AND post_type= %s", $page_title, $post_type));
        if ( $post )
            return get_post($post, $output);

    return null;
}

Il vousmanque unparamètre defonction.Jetez unnullpour le deuxièmeparamètrefacultatif $ outputet cettefonction devraitfonctionnerpour vous.

 get_page_by_title('My post title', null, 'customposttype');
 

Je viens de rencontrer lemêmeproblèmeet l'ajout de la valeurnull l'a corrigépourmoi.

You are missing a function parameter. Throw a null in for the second optional paramter $output and this function should work for you.

get_page_by_title('My post title', null, 'customposttype');

I just ran into the same issue and adding the null fixed it for me.

J'aitendance à éviter les requêtes directes debase de données.À laplace,j'utilise l'objet WP_Querypour analyser les choses àmaplace.

Il s'agit,en gros,d'unefonction quej'utilise dans l'un demesthèmespour obtenir un articlebasé sur un slug donné:

 function get_post_id( $slug, $post_type ) {
    $query = new WP_Query(
        array(
            'name' => $slug,
            'post_type' => $post_type
        )
    );

    $query->the_post();

    return get_the_ID();
}
 

Cela créera une requête utilisant l'API WPpour récupérer unepublication d'untype spécifique avec un slug donné,exécutera lesfonctions deboucle régulières sur le résultatet retournera l'ID de lapublication.Vouspouvez également l'utiliserpour renvoyer l'intégralité dumessageen modifiant unpeu lafonction,mais c'est à vous de décider.

I tend to shy away from direct DB queries. Instead, I use the WP_Query object to parse things for me.

This is, basically, a function I use in one of my themes to get a post based on a given slug:

function get_post_id( $slug, $post_type ) {
    $query = new WP_Query(
        array(
            'name' => $slug,
            'post_type' => $post_type
        )
    );

    $query->the_post();

    return get_the_ID();
}

This will create a query using the WP API to fetch a post of a specific type with a given slug, will run the regular loop functions on the result, and return the ID of the post. You could also use it to return the entire post by modifying the function a bit, but that's up to you.

Cela datemaintenant de quelques années,mais cela apparaîttoujours lors de la recherche sur Google.Alors,voici unmoyen simple de lefaire:

 $page = get_page_by_title( 'my post title' );
 

ou

 $page = get_post_ID_by_title('my post title', OBJECT, 'customposttype');
 

Ensuite,utilisez simplement l'objet $pagepour récupérer l'ID:

 $page->ID
 

This is a few years old now, but it still pops up when searching for this on Google. So, here's a simple way to do it:

$page = get_page_by_title( 'my post title' );

or

$page = get_post_ID_by_title('my post title', OBJECT, 'customposttype');

Then just use the $page object to grab the ID:

$page->ID

Actuellement (WP> 4.9.2),voustrouverez votre "tout" article/page donné,etc.partitre/slug de cettefaçon:

 $page = get_posts(
    array(
        //'name'      => 'your-post-slug', // by post slug
        'title'      => 'Your post title', // by post title
        'post_type' => 'page' // post type of your preference
    )
);

if ($page = $page[0]) // First/lowest ID taken if many objects
{
    // Then you do whatever is needed...
    // $id = $page->id;
    // $content = $page->post_content;
    // or $content = apply_filters('the_content', $page->post_content);
    // etc.
}
 

Currently (WP >4.9.2) you'll find your "any" given post/page etc. by title/slug this way:

$page = get_posts(
    array(
        //'name'      => 'your-post-slug', // by post slug
        'title'      => 'Your post title', // by post title
        'post_type' => 'page' // post type of your preference
    )
);

if ($page = $page[0]) // First/lowest ID taken if many objects
{
    // Then you do whatever is needed...
    // $id = $page->id;
    // $content = $page->post_content;
    // or $content = apply_filters('the_content', $page->post_content);
    // etc.
}
