Line 32 should have ;

Just removed line 31, thanks

@GrindamN

To fully remove validation for the application field you may leave only this callback:

function remove_admin_required_validation( $errors ) {
	$key = array_search( $errors['empty'], 'jb-application-contact' );
	if ( false !== $key ) {
		unset( $errors['empty'][ $key ] );
	}
	return $errors;
}
add_filter( 'jb_ajax_job_validation_errors', 'remove_admin_required_validation' );

Yeah I got that part from gist @nikitasinelnikov

However it still seems that the metabox is expecting some value to be inserted (either e-mail or https://url.com) so that the post can be updated. With the code above it acts the same like when validation is on, only without ajax check and notice error.

@GrindamN I added some changes to the remove_admin_required_validation function and it should work as expected without any validation

@nikitasinelnikov Tried it. Now it doesn't work even you have empty field or if you put url or Email. Same as above.

It removes all validations from the Application contact field. But if you need some of them you could remove some parts of this code or customize it in your necessary way.

If you need to remove only the "required" validation leave only this part:

        if ( empty( $_POST['data']['jb-application-contact'] ) ) {
		if ( isset( $errors['empty'] ) ) {
			$key = array_search( 'jb-application-contact', $errors['empty'], true );
			if ( false !== $key ) {
				unset( $errors['empty'][ $key ] );
				if ( 0 === count( $errors['empty'] ) ) {
					unset( $errors['empty'] );
				}
			}
		}
	}

Hmm. If possible I would remove the whole field, since I use FluentForms to collect the data in a separate custom post type.

It's not a problem to delete this field from a forms

E.g. change the loop in the first function for the frontend:

foreach ( $args['sections']['job-details']['fields'] as $key => $field_data ) {
	if ( 'job_application' === $field_data['id'] ) {
		unset( $args['sections']['job-details']['fields'][ $key ] );
	}	
}

And similar changes for the admin field loop. Callbacks for validation leave the same but can unset errors without conditions in them.

Quick question: Would it be possible to prepopulate the field with https://test.com somehow?

Hi @GrindamN

Sorry for the delay, you may repopulate the field via using the 'value' argument:

foreach ( $args['sections']['job-details']['fields'] as $key => &$field_data ) {
	if ( 'job_application' === $field_data['id'] && empty( $field_data['value'] ) ) {
		$field_data['value'] = 'https://test.com/';
	}	
}

Best Regards!
