Hi,
I have a custom field that I use to store a publication ID from a third party app. Since it’s a unique ID in the third-party platform, I want to avoid having a duplicate on WordPress too. I added this code to my function.php, and it’s working well in the WordPress admin, but I need to do the same thing through a custom endpoint that we use to push content to avoid having duplicate publications.
Here’s the snippet in function.php:
add_filter('acf/validate_value/name='.'podboxx_id', 'acf_unique_value_field', 10, 4);
function acf_unique_value_field($valid, $value, $field, $input) {
if (!$valid || (!isset($_POST['post_ID']) && !isset($_POST['post_id']))) {
return $valid;
}
if (isset($_POST['post_ID'])) {
$post_id = intval($_POST['post_ID']);
} else {
$post_id = intval($_POST['post_id']);
}
if (!$post_id) {
return $valid;
}
$post_type = get_post_type($post_id);
$field_name = $field['name'];
$args = array(
'post_type' => $post_type,
'post_status' => 'publish, draft, trash',
'post__not_in' => array($post_id),
'posts_per_page' => -1,
'meta_query' => array(
array(
'key' => 'podboxx_id',
'value' => $value
)
)
);
$query = new WP_Query($args);
if (count($query->posts)){
return 'This Value is not Unique. Please enter a unique '.$field['label'];
}
return true;
}
Here’s what I have right now as my custom endpoint:
public function api_endpoint_add_post($request) {
$form_data = $request->get_params();
$post_content = $request->get_param('post_content');
$post_title = $request->get_param('post_title');
$post_excerpt = $request->get_param('post_excerpt');
$url = $request->get_param('url');
$podboxx_id = $request->get_param('podboxx_id');
$titre_emission = $request->get_param('titre_emission');
$category = $request->get_param('category');
$post_tag = $request->get_param('post_tag');
$featured_image = $request->get_param('featured_image');
$post_content = $post_content ?? '';
$post_excerpt = $post_excerpt ?? '';
$new_categories = array();
if($featured_image){
$attach_id = $this->upload_image_from_url($featured_image);
}
if($category){
$categories = explode(',', $category);
foreach ($categories as $single_category) {
$term = term_exists( $single_category, 'category' );
if(!$term['term_id']){
$category_id = wp_insert_term($single_category, 'category');
$new_categories[] = $category_id;
}else{
$new_categories[] = $term['term_id'];
}
}
}
if($post_tag){
$post_tag = explode(',', $post_tag);
}
if ( ... something here ...){
$status = '200';
$message = 'Post with same content is already Exist.';
$data = '';
}else{
...
}
I want to adapt the code to make it filter duplicate posts through REST API. I’ve tried it but I’m not having success
