Hi,

Sorry I missed the auto resolve on post https://toolset.com/forums/topic/trying-to-populate-the-wp-title-field-with-a-few-other-fields/

I'm trying it now, and it's failing, saying that the field Title is required, not letting me save..

[Gerard]

I get this: hidden link

Is it possible to make Title "NOT required"?

[Christian Cox]

Hi, can you delete the title field from this Form? Edit the form and remove the input field. Then the error will not be displayed on the front-end of the site, and the title will be set automatically.

[Gerard]

Yes!!! getting closer.. Thanks

I see the logic I think, it was blocked since the field was on the form AND "required"?

So, the Title field now gets filled with only the comma, but the field values did not copy over..

Yes, that's right. If you remove the title field from the Form, the error will not be triggered.

So, the Title field now gets filled with only the comma, but the field values did not copy over..
For reference, from the other ticket:

function gg_fill_full_name( $post_id, $post ){
 
global $wpdb;
     
    if ( $post_id == null || empty($_POST) )
        return;
 
    if ( wp_is_post_revision( $post_id ) )
        $post_id = wp_is_post_revision( $post_id );
 
    if ( empty( $post ) )
        $post = get_post($post_id);
 
     
    if ( 'application' == $post->post_type ) {
         
                $firstname = get_post_meta( $post_id, 'wpcf-first-name', true );
                               $middlename = get_post_meta( $post_id, 'wpcf-middle-name', true );
                               $lastname = get_post_meta( $post_id, 'wpcf-last-name', true );
                               $suffix = get_post_meta( $post_id, 'wpcf-name-suffix', true );
 
            $result = $lastname . " " . $suffix . ", " . $firstname . " " . $middlename;
 
            if ( !empty($result) ) {
                $where = array( 'ID' => $post_id );
                $wpdb->update( $wpdb->posts, array( 'post_title' => $result ), $where );
            }
        }
 
 
}
 
add_action( 'save_post', 'gg_fill_full_name', 30, 2 );

One thing I see is here:

            $result = $lastname . " " . $suffix . ", " . $firstname . " " . $middlename;
            if ( !empty($result) ) {

The $result variable will never be empty, because there are spaces and a comma in the concatenated string. I'm not sure why the !empty check is there, but this could be the problem.

Then you could also try bumping up the priority to 100:

add_action( 'save_post', 'gg_fill_full_name', 100, 2 );

If neither of these solves the problem, I'll need to take a closer look.

[Gerard]

I bumped the priority to 100, and removed the "IF !empty" check, same result, only the "," made it..

if I edit directly from the WP backend, then it works, even with prior settings.

Systems Test, please ignore this reply.

[Gerard]

O.K.

[Gerard]

follow up:

Hoping it was a priority issue, I've now tested with 10, with 100, with 999, and with 1500. no difference.

Hi Shane,

You can find site access in this other ticket: https://toolset.com/forums/topic/can-post-forms-be-used-by-guests-to-create-posts/

Hi Gerard,

As christian is currently on vacation, I will be handling this issue.
Could you let me know if this is for a Toolset form on the frontend ?

Thanks,
Shane

[Gerard]

Hi,

Yes it is. The one in that other ticket at https://toolset.com/forums/topic/can-post-forms-be-used-by-guests-to-create-posts/ 🙂

Hi Gerard,

Could you change this line.

add_action( 'save_post', 'gg_fill_full_name', 30, 2 );

To

    add_action('cred_save_data', 'gg_fill_full_name',10,2);

Since it is a CRED form you should use this instead.

Thanks,
Shane

Hi, I tried it with both 10, and 100, and the result is that instead of filling the Title field with the other field values, it writes:

CRED Auto Draft 3519dcec72882683e20445031bfdd404

Hi Gerard,

I thinks a rewritten solution would be needed for you.

As you had the code in the original solution please try it again.

function gg_fill_full_name( $post_id, $post ){
if ( 'application' == $post->post_type ) {
$firstname = get_post_meta( $post_id, 'wpcf-first-name', true );
$middlename = get_post_meta( $post_id, 'wpcf-middle-name', true );
$lastname = get_post_meta( $post_id, 'wpcf-last-name', true );
$suffix = get_post_meta( $post_id, 'wpcf-name-suffix', true );

$result = $lastname . " " . $suffix . ", " . $firstname . " " . $middlename;
if ( !empty($result) ) {
   $my_post = array(
  'ID' => $post_id,
   'post_title' => $result,
);
// Update the post into the database
wp_update_post( $my_post, $wp_error );
}
}
}

add_action('cred_save_data', 'gg_fill_full_name',10,2);

As you mentioned with minesh you were getting an error 500. Could you enable the wordpress debugging and then let me know the error ?

Thanks,
Shane
