Hi John,
Thanks for your help
My problem was general PHP, I did PHP in PHP.
So I opened and closed correctly my php tag
Thank you for helping me on the fact that I used the code of the post_object like in the documentation here
Thank you for telling me that I could use the get_field simply
<div class="experiences">
<?php
// Check value exists.
if( have_rows('experiences') ):
echo '<h2 data-fontsize="24" data-lineheight="27">Expériences</h2><table class="listexp"><tr class="title"><td class ="date-in">Du</td><td class ="date-out">Au</td><td class ="agrement">Agrément du centre</td><td class ="adresse">Adresse</td><td class ="notif">Notification</td></tr>';
// Loop through rows.
while ( have_rows('experiences') ) : the_row();
// Case: Paragraph layout.
if( get_row_layout() == 'experience' ):
$du = get_sub_field('date_entree');
$au = get_sub_field('date_sortie');
$ctrlid = get_sub_field('agrement_du_centre');
$notif = get_sub_field('notification_ch_ctrl'); ?>
<?php echo '<tr><td class ="date-in">' . $du . '</td>' ?>
<?php echo '<td class ="date-out">' . $au . '</td>' ?>
<?php echo '<td class ="agrement">' ?>
<?php echo get_the_title( $ctrlid ); ?>
<?php echo '</td>' ?>
<?php echo '<td class ="adresse">' ?>
<?php the_field('cp_du_centre', $ctrlid); ?> <?php the_field('ville_du_centre', $ctrlid); ?>
<?php echo '</td>' ?>
<?php echo '<td class ="notif"><a href="' . $notif . '" target="_blank"><i class="fa fa-file-pdf-o"></i></a></td></tr>'; ?>
<?php endif;
endwhile;
echo '</table>';
else:
echo '<h2 data-fontsize="24" data-lineheight="27">Nombre de VTP par année</h2><p><i>Aucune valeur</i></p>';
endif; ?>
</div>
In the input form in wp_admin : $ctrlid is a post selector that returns the id of the selected post.
This code could be light, I would take the time to heal my code later
