どうぞ！

 <?php

Here you go !

<?php
$my_id = 5369;
$post_id_5369 = get_post($my_id);
$content = $post_id_5369->post_content;
$content = apply_filters('the_content', $content);
$content = str_replace(']]>', ']]>', $content);
echo $content;
?>

 $post   = get_post( 42 );

$output =  apply_filters( 'the_content', $post->post_content );

echo $output;

このコードを使用できます.問題なく動作します. page_id=19をページ番号に変更します:

 <?php $the_query = new WP_Query( 'page_id=19' ); ?>

<?php while ($the_query -> have_posts()) : $the_query -> the_post();  ?>

                       <?php the_excerpt(); ?>


     <?php endwhile;?>
 

you can use this code it is work fine change page_id=19 with your page number:

<?php $the_query = new WP_Query( 'page_id=19' ); ?>

<?php while ($the_query -> have_posts()) : $the_query -> the_post();  ?>

                       <?php the_excerpt(); ?>


     <?php endwhile;?>

ループに入っている場合は、次のようにします.

 <?php
$my_excerpt = get_the_excerpt();
if ( $my_excerpt != '' ) {
    // Some string manipulation performed
}
echo $my_excerpt; // Outputs the processed value to the page
 

またはIDをお持ちの場合は、投稿を取得してから、post_excerptメンバー変数を訴えます

例

 $post = get_post( $post_id );
echo $post->post_excerpt;
 

If you're in the loop do this:

<?php
$my_excerpt = get_the_excerpt();
if ( $my_excerpt != '' ) {
    // Some string manipulation performed
}
echo $my_excerpt; // Outputs the processed value to the page

Or if you have an ID, get the post then sue the post_excerpt member var

e.g.

$post = get_post( $post_id );
echo $post->post_excerpt;

このコードを試して、page_idを変更してください:

 <?php $my_query = new WP_Query('page_id=20');
while ($my_query->have_posts()) : $my_query->the_post();
$do_not_duplicate = $post->ID;?>
 <h3><?php the_title(); ?></h3>
    <div class="text">

        <?php echo wp_trim_words( get_the_content(), 15, '...' ); ?>
 <a href="<?php echo get_page_link(); ?>" class="read-more">Read More</a>
    </div>

 <?php endwhile; ?>
 

Try this code and just change your page_id:

<?php $my_query = new WP_Query('page_id=20');
while ($my_query->have_posts()) : $my_query->the_post();
$do_not_duplicate = $post->ID;?>
 <h3><?php the_title(); ?></h3>
    <div class="text">

        <?php echo wp_trim_words( get_the_content(), 15, '...' ); ?>
 <a href="<?php echo get_page_link(); ?>" class="read-more">Read More</a>
    </div>

 <?php endwhile; ?>

私のようなワンライナー中毒者のために.ページIDで69を変更します.

 <?= apply_filters('the_content', get_post(69)->post_content); ?>
 

For one liner addicts like me. Change 69 by your page ID.

<?= apply_filters('the_content', get_post(69)->post_content); ?>
