no usability

Looks fixed to me. I now see:

array(1) { [“group”]=> array(1) { [1]=> array(3) { [“title”]=> string(6) “hicadv” [“textarea”]=> string(224) “Utvel et laniet dolestion con premo omnisitatur antis endis prepre eicilici nesteceaque ma dolenes simuscidit odisitem eossim repratur, quia cus et fuga. Soluptae. At vel molla quo ist erspelles utemquunt. > https://www.hicadv.it” [“image”]=> NULL } } }

Remove the following lines:

<?php
$fields = ff_get_all_fields_from_section('group', 'meta', 'post', $post->ID);
var_dump($fields);
?>

Replace them with:

<?php
$fields = ff_get_all_fields_from_section('group', 'meta', 'post', $post->ID);

if(!empty($fields)) {
	foreach($fields as $field) {
		echo '<h3>' . $field['title'] . '</h3>';

		echo wpautop($field['textarea']);

		echo '<p><img src="' . $field['image'] . '" alt="" /></p>';
	}
}
?>

sorry dude, now everything is disappeared

so, i’ve update wordpress and your plugin to the latest version

i’ve erased everything and i did new fields, the new code is here:

i see good in backend and media file works pretty good.

i use this code to the page template
<? $fields = ff_get_all_fields_from_section(‘Links’, ‘grouplinks’, ‘meta’, ‘post’, $post->ID);
var_dump($fields);?>
but it returns the value NULL

can you still help me? thanks

Please check in the backend if whether the fields on the page you are viewing actually have any content or not? If you rename fields, previous content will not be retained.
