Récupérer le contenu du message en dehors de la boucle

Vouspouvez utiliser get_page() pour renvoyer le $post objet d'unepage statique:

 $page_id = 302;
$page_object = get_page( $page_id );
echo $page_object->post_content;

Demême,vouspouvez utiliser get_post() pour renvoyer le$post objet d'unmessage:

 $post_id = 302;
$post_object = get_post( $post_id );
echo $post_object->post_content;
 

You can use get_page() to return the $post object of a static page:

$page_id = 302;
$page_object = get_page( $page_id );
echo $page_object->post_content;

Edit

Similarly, you can use get_post() to return the $post object of a post:

$post_id = 302;
$post_object = get_post( $post_id );
echo $post_object->post_content;

pour obtenir le contenu dumessageen dehors de laboucle,vouspouvez écrire quelque chose comme ça

 global $post;
$content = $post->post_content;

if ( !empty( $content ) ) :
    echo $content;
endif;
 

to get the content of the post outside the loop you can write something like this

global $post;
$content = $post->post_content;

if ( !empty( $content ) ) :
    echo $content;
endif;

Si votre contenu contient des codes courts,vous devez utiliser:

 $post_id = 22;        
$post_object = get_post( $post_id );        
echo do_shortcode( $post_object->post_content );
 

If your content include shortcodes, you should use:

$post_id = 22;        
$post_object = get_post( $post_id );        
echo do_shortcode( $post_object->post_content );

Par souci d'exhaustivité,en s'appuyant sur le commentaire de Tim ci-dessuset inspiré de l'article de Stephen Harris ,la solution quipermet d'utiliser the_content()est:

 $post_id = 302;
global $post;
$post = get_post($post_id);
setup_postdata( $post );
the_content();
wp_reset_postdata( $post );
 

Etpar conséquent,lesfiltres sont appliqués (desparagraphes serontinsérés,etc.)et les codes courtsfonctionnent.

For completeness, building on Tim's comment above and inspired by Stephen Harris's article, the solution that enables use of the_content() is:

$post_id = 302;
global $post;
$post = get_post($post_id);
setup_postdata( $post );
the_content();
wp_reset_postdata( $post );

And hence filters get applied (paragraphs will be inserted etc.) and shortcodes work.

Puisque vous connaissez votre ID depublication cible (302),vouspouveztrouver utile cette syntaxe abrégée que vouspouvez utiliser hors de laboucle (bien que sesperformances soient àpeuprès lesmêmes que danstoute autreméthode alternative :)

 echo(get_post_field('post_content',302));
 

Since you know your target post ID (302), you may find useful this shorthand syntax that you can use out of the loop (though its performance is pretty much the same as in any other alternative method:)

echo(get_post_field('post_content',302));

Vouspouvez utiliser lafonction get_post_data()pour obtenir unmessage hors de laboucle.Placez ce code dansfunctions.php

 function get_post_data($postId) {
    global $wpdb;
    return $wpdb->get_row("SELECT * FROM $wpdb->posts WHERE ID=$postId");
}
 

puis ajoutez cetextraitpourplus de contrôle sur leprocessus

 <?php $data = get_post_data(302);
    echo $data->post_date;     // post date
    echo $data->post_title;    // post title
    echo $data->post_content;  // post content
    echo $data->comment_count; // comments number
?>
 

You can use the get_post_data() function to get post outside the loop. Place this code in functions.php

function get_post_data($postId) {
    global $wpdb;
    return $wpdb->get_row("SELECT * FROM $wpdb->posts WHERE ID=$postId");
}

and then add this snippet for more control on the process

<?php $data = get_post_data(302);
    echo $data->post_date;     // post date
    echo $data->post_title;    // post title
    echo $data->post_content;  // post content
    echo $data->comment_count; // comments number
?>

Vouspouvez utiliser,comme dit,la solution avec get_postet $post_object->post_content,maisn'oubliezpas d'ajouter une vérification avant d'utiliser cemessageobjet:

 function get_post_content( $post_id = null ) {
    $post_object = get_post( $post_id );
    if ( ! $post_object ) { return ''; }
    //else

    return apply_filters('the_content', $post_object->post_content);
}

echo get_post_content( $other_post_id );
 

You can use, as said, the solution with get_post and $post_object->post_content, but don't forget to add a check before you use that post object:

function get_post_content( $post_id = null ) {
    $post_object = get_post( $post_id );
    if ( ! $post_object ) { return ''; }
    //else

    return apply_filters('the_content', $post_object->post_content);
}

echo get_post_content( $other_post_id );

Vouspouvez simplement appelerget_the_content (postId)

 <?php echo get_the_content($postId); ?>
 

You can simply call get_the_content(postId)

<?php echo get_the_content($postId); ?>

utilisez wp_reset_postdata(); celafonctionnera .. (modifié)

 <?php 
$args = array(
        'post_type' => 'posttype',
        'p' => 'post_id'
       );
$the_query = new WP_Query( $args );
if( have_posts() ) : while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
        <?php the_content(); ?>
    <?php endwhile; endif; 
wp_reset_postdata();
?>
 

posttypepeut être "post","page" ou votretype depostpersonnalisé.Ici,p=302est votreidentifiant demessage. J'espère que celafonctionnera.

use wp_reset_postdata(); it will work.. (edited)

<?php 
$args = array(
        'post_type' => 'posttype',
        'p' => 'post_id'
       );
$the_query = new WP_Query( $args );
if( have_posts() ) : while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
        <?php the_content(); ?>
    <?php endwhile; endif; 
wp_reset_postdata();
?>

posttype can be "post" , "page" or your custom post type. Here p=302 is your post id.. Hope it will work.

vouspouvezmettre du contenu dans une catégorie Xet utiliser query_post avanttout comme ceci:

     <?php query_posts('cat=X&showposts=1'); ?>
    <?php while (have_posts()) : the_post(); ?>
          <?= get_the_content(); ?>
    <?php endwhile; ?>
 

you can put content in a category X and use query_post before while like this :

    <?php query_posts('cat=X&showposts=1'); ?>
    <?php while (have_posts()) : the_post(); ?>
          <?= get_the_content(); ?>
    <?php endwhile; ?>
