Comment obtenir la date de publication de l'article en dehors de la boucle?

get_the_date doit être utilisé dans laboucle.En dehors de laboucle,utilisez get_the_time .

 $posts = get_posts(array('numberposts'=>-1)); //Get all published posts
foreach ($posts as $post){
    echo get_the_time('Y-m-d', $post->ID); //Echos date in Y-m-d format.
}
 

Pensez à remplacer 'Y-m-d' dans cetexemplepar get_option('date_format') car cela affichera la date selon votreparamètre deformat de date dans wp-admin.

get_the_date must be used inside the Loop. For outside the loop use get_the_time.

$posts = get_posts(array('numberposts'=>-1)); //Get all published posts
foreach ($posts as $post){
    echo get_the_time('Y-m-d', $post->ID); //Echos date in Y-m-d format.
}

Consider replacing 'Y-m-d' in this example with get_option('date_format') as this will display the date as per your date format setting in wp-admin.

Quelques soultionsmodernes

Première solution

 <?php echo get_the_date('j F Y', get_the_ID()) ?>
 

Solution deux

 <?php the_time(get_option('date_format')) ?>
 

Some Modern soultions

Solution One

<?php echo get_the_date('j F Y', get_the_ID()) ?>

Solution Two

<?php the_time(get_option('date_format')) ?>

Vouspouvez utiliser get_post () ou get_post_field () pour cela,les deuxfonctionnenten dehors de laboucle.

 $post_object = get_post($id);
$post_date = date( 'F jS, Y', strtotime( $post_object->post_date ) );
 

Une liste complète des valeurs renvoyéesparget_post:

 WP_Post Object
(
    [ID] =>
    [post_author] =>
    [post_date] => 
    [post_date_gmt] => 
    [post_content] => 
    [post_title] => 
    [post_excerpt] => 
    [post_status] =>
    [comment_status] =>
    [ping_status] => 
    [post_password] => 
    [post_name] =>
    [to_ping] => 
    [pinged] => 
    [post_modified] => 
    [post_modified_gmt] =>
    [post_content_filtered] => 
    [post_parent] => 
    [guid] => 
    [menu_order] =>
    [post_type] =>
    [post_mime_type] => 
    [comment_count] =>
    [filter] =>
)
 

You can use get_post() or get_post_field() for this, both work outside the loop.

$post_object = get_post($id);
$post_date = date( 'F jS, Y', strtotime( $post_object->post_date ) );

A full list of values returned by get_post:

WP_Post Object
(
    [ID] =>
    [post_author] =>
    [post_date] => 
    [post_date_gmt] => 
    [post_content] => 
    [post_title] => 
    [post_excerpt] => 
    [post_status] =>
    [comment_status] =>
    [ping_status] => 
    [post_password] => 
    [post_name] =>
    [to_ping] => 
    [pinged] => 
    [post_modified] => 
    [post_modified_gmt] =>
    [post_content_filtered] => 
    [post_parent] => 
    [guid] => 
    [menu_order] =>
    [post_type] =>
    [post_mime_type] => 
    [comment_count] =>
    [filter] =>
)

essayez comme ça

 $getPosts = $wpdb->get_results( 
"
    SELECT ID, post_date,post_title
    FROM $wpdb->posts
    WHERE post_status = 'publish' 
        AND post_type = 'post'
        ORDER BY ID ASC
    "
);

foreach ( $getPosts as $myPost ) {
    $id = $myPost->post_date;
    echo $myPost->ID.' | '. $myPost->post_title.' | '. get_the_date("Y-m-d",$id ).'<br />';
}
 

modifier

get_the_time Renvoie l'heure dumessage actuel à utiliser dans PHP. Iln'affichepas l'heure. Pour afficher l'heure d'unmessage,utilisezthe_time (). Cettebalise doit être utilisée dans The Loop.

get_the_date Labalise demodèleget_the_date récupère la date à laquelle le $ actuel lemessage a été écrit. Contrairement àthe_date (),cettebalise retourneratoujours la date. Modifiez la sortie avec lefiltre «get_the_date».

Est-ce queje manque quelque choseici?

try like this

$getPosts = $wpdb->get_results( 
"
    SELECT ID, post_date,post_title
    FROM $wpdb->posts
    WHERE post_status = 'publish' 
        AND post_type = 'post'
        ORDER BY ID ASC
    "
);

foreach ( $getPosts as $myPost ) {
    $id = $myPost->post_date;
    echo $myPost->ID.' | '. $myPost->post_title.' | '. get_the_date("Y-m-d",$id ).'<br />';
}

edit

get_the_time Returns the time of the current post for use in PHP. It does not display the time. To display the time of a post, use the_time(). This tag must be used within The Loop.

get_the_date The get_the_date template tag retrieves the date the current $post was written. Unlike the_date() this tag will always return the date. Modify output with 'get_the_date' filter.

Am I missing something here?
