Tell us what you are trying to do?

I have a follow up question to my last question (https://toolset.com/forums/topic/access-custom-checkboxes-field-_postwpcf-slug-as-an-array/#post-1919451)

After submitting a CRED Form, I try to clone the submitted post, modify it slightly and insert it into the database. Works very good so far, but I encountered a problem with a repeating picture field...

'wpcf-repeating-picture-field' =>$_POST['wpcf-repeating-picture-field'], (see code below) ... doesn't work

// Create post object
$termin = array(
'post_title' => $day,
'post_status' => 'publish',
'post_type' => 'event',              
  
'meta_input'  => array ( 
'wpcf-repeating-picture-field' =>$_POST['wpcf-repeating-picture-field'],      
),
    
);


// Insert the post into the database
$termin_id = wp_insert_post( $termin );

I also tried ...

// add pictures   
$saved_pictures = get_post_meta($post_id,'wpcf-repeating-picture-field',true);    
foreach($saved_pictures as $pictures):
add_post_meta($termin_id, 'wpcf-repeating-picture-field', $pictures, false);         
endforeach;

... but it only adds an empty element to the new post.

I'm looking for a way to access a repeating field and then insert it into a new posts

Is there any documentation that you are following?

Hi, the solution depends on the options in your Post Form configurations, as seen in the screenshot here.
1. Is the Form set to submit using AJAX?
2. Is the Form set to use the Media Library for images?

Please share your configurations and I can offer some additional guidance.

Hi Christian,

many thanks for your answer.
I attached an image with my Post Form configuration.

Kind regards

Okay I see, thank you. The following example shows how you can access custom field images as an array in the $_POST superglobal in a cred_save_data callback, then loop over the images in that array and insert them in a new post using wp_insert_post and add_post_meta:

add_action('cred_save_data', 'my_save_data_action',10,2);
function my_save_data_action($post_id, $form_data) {
  $forms = array( 123 );
  if ( in_array( $form_data['id'], $forms ) )
  {
    $gallery = $_POST['wpcf-fieldslug'];
    $new_book_args = array(
      'post_title' => 'cloned book test from ' . $post_id,
      'post_status' => 'publish',
      'post_type' => 'book'
    );

    // Insert the cloned post into the database
    $new_book_id = wp_insert_post( $new_book_args );
    
    foreach( $gallery as $img ){
      add_post_meta($new_book_id, 'wpcf-fieldslug', $img, false);
    }
  }
}

It's similar to some of the code you shared, but instead of using get_post_meta I am accessing the images directly in the $_POST superglobal.

Many thanks Christian.

It works perfectly.

I have a similar problem with another repeating field (date). I need to iterate over it and access the information, that is saved inside the['datepicker']. It would be lovely, if you could give me a hint. I hoped that it would work similar to the picture repeating field, but it doesn't....

// random days   
$random_days = $_POST['wpcf-rask-weitere-tage']['datepicker']; 
foreach($random_days as $k=>$v) {

$day = $v['datepicker'];

}

[Christian Cox]

Instead of looping over the datepicker array value, loop over the field itself. Here is a small modification that adjust your foreach loop source:

$random_days = $_POST['wpcf-rask-weitere-tage']; 
foreach($random_days as $k=>$v) {
 
  $day = $v['datepicker'];
  add_post_meta(12345, 'wpcf-rask-weitere-tage', $day, false);
}

Change 12345 to a variable containing the new (clone) post ID returned by wp_insert_post.

Thanks Christian 🙂 You're the man!
Works perfectly
