It worked great ! Thanks a lot again!
Thanks for your answer !
I tried to use your code but it display an error and I can’t find why :
Parse error: syntax error, unexpected ‘,’ in /home/guillaummg/www/faview/wp/wp-content/themes/ffaview/functions.php on line 209
add_filter( 'posts_distinct', 'cf_search_distinct' );
// PREVENT POST THAT ALREADY EXIST
add_filter('acf/validate_value/name=lien_video', 'validate_lien_video_filter', 10, 4);
add_filter('acf/load_value/name=hidden_post_id', 'add_post_id_as_value'), 10, 3);
function add_post_id_as_value($value, $post_id, $field) {
return $post_id;
}
function validate_lien_video_filter($valid, $value, $field, $input) {
$post_id_field_key = 'field_569ce8b4cba44';
if (!$valid || $value == '' || !isset($_POST['acf'][$post_id_field_key])) {
return $valid;
}
// change the field key below to the field key for your
// hide_post_id_field field
$post_id = $_POST['acf'][$post_id_field_key];
global $post;
$args = array(
'post_type' => 'videos', // or your post
'post__not_in' => array($post_id), // do not check this post
'meta_query' => array(
array(
'key' => 'lien_video',
'value' => $value
)
)
);
$query = new WP_Query($args);
if (count($query->posts)) {
// found at least one post that
// already has $value
$valid = 'There is already a post using this video';
}
return $valid;
}
It worked great ! Thanks a lot !
Here is my code if it can help someone else :
The name of my field is : lien_video
Name of my custom posts : videos
<?php
add_filter('acf/validate_value/name=lien_video', 'validate_lien_video_filter', 10, 4);
function validate_lien_video_filter($valid, $value, $field, $input) {
if (!$valid || $value == '') {
return $valid;
}
// query posts for the same value
// for more info see
// http://codex.wordpress.org/Class_Reference/WP_Query
global $post;
$args = array(
'post_type' => 'videos', // or your post
'post__not_in' => array($post->ID), // do not check this post
'meta_query' => array(
array(
'key' => 'lien_video',
'value' => $value
)
)
);
$query = new WP_Query($args);
if (count($query->posts)) {
// found at least one post that
// already has $value
$valid = 'There is already a post using this video';
}
return $valid;
}
?>
