Wordpress get content of page (with php inside) - php

Question

I would like to be able to have the html content of a wordpress page. I try to use this kind of code :
$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;
But it returns empty an empty string whereas when I access to the page, the content is not empty. Indeed, there is php code inside the content of the page I would like to get. So, how I can do to get the content of this page knowing that there is php code inside?
data content :
<div id="content" class="oe">
<?php $loop = new WP_Query( array('post_type'=>'mcm')); ?>
<div id="slid" class="div-slider">
<?php
/* get value */
$appercu_collection = get_post_custom_values ( "o" );
if ($appercu_collection) { // si appercu
class Image {
public $link;
public $image;
}
/* init value */
$imageCollection = array ();
/* complet collection */
foreach ( $appercu_collection as $img ) {
$img_tmp = new Image ();
$img_tmp->image = wp_get_attachment_image_src( $img , 'medium' )[0];
array_push ( $imageCollection, $img_tmp );
}
display_slider ( $imageCollection );
}
?>
</div>
<div id="content-meta">
<div class="meta-detail-header"><?php echo get_post_custom_values ( "_at" )[0]; ?></div>
<div class="meta-detail-title"><?php the_title(); ?></div>
<div class="audio">
<div id="audio-inner">
<?php $au = get_post_custom_values("_au");
if ($au) {
$urlguid = wp_get_attachment_url ( $au [0] );
if ($urlguid) {
display_audio ( $urlguid );
}
}
?>
</div>
</div>
</div>
<div id="ex">
<?php
$newdebut = get_long_formatted_date( $date_debut[0] );
$newfin = get_long_formatted_date( $date_fin[0] );
?>
<div id="expo-temp-dates"><?php echo sprintf( __( 'From %s to %s' , 'wptouch-pro' ) , $newdebut , $newfin );?></div>
<?php
$tar = get_post_custom_values("_tarif");
if($tar) { ?>
<div id="exprice"><?php echo $tar[0]; ?></div>
<?php }?>
</div>
<div id="content-o" >
<!-- GET Content -->
<div id="content-description" class="detail-container">
<?php display_zoom_controls(); ?>
<?php echo wpautop( wptouch_the_content() ); ?>
</div>
<!-- GET BONUS -->
<div id="content-bottom-sticky">
<a href="<?php echo $url_guide;?>"
class="tappable-button tappable dark" role="Button"><?php _e( 'TUIDE' , 'wptouch-pro' ); ?></a>
</div>
</div>
<?php endif; ?>
<!-- inside intervalle -->
<?php endwhile;
wp_reset_postdata();?>
<?php if( ! $content) { ?>
<div id="title" class="title">
<h2><?php _e( 'N' , 'wptouch-pro' ); ?></h2>
</div>
<?php }?>

Answer 1

I finally resolve my problem by doing an ajax request to my page and get the content thanks to
wp_remote_get . Indeed, It was a page with a custom type post and custom fields.
Here is my code :
$resp = wp_remote_retrieve_body( wp_remote_get($url,$option));
$doc = new DOMDocument();
$doc->loadHTML($resp);
$element = $doc->getElementById('content');
$content = $doc->saveHTML($element);
$content contains the html content of the element with the id "content" of the page whose url is $url.
