Problem with validation of image size when editing post

Ce fil est résolu. Voici une description du problème et la solution proposée.

Problem: I am trying to use the CRED API validation hook to verify an image size, but the custom field value always includes the "-150x150" dimensions in its URL. This breaks my image size validation code.

Solution: Remove the -150x150 dimensions from the URL using str_replace, so you can check the original image dimensions:

$orig = str_replace('-150x150', '', $fields['_featured_image']['value']);
            $check = getimagesize( $orig );

Hi, I have a validation of featured image size in CRED content forms (for creation and editing CPT). There is a problem when I want to save some changes of CPT in CRED Edit form. I get an error that the image has another dimensions than it´s required (300x200px). If I hover over the image I see that it gives "-150x150.png" after name of image. But the image uploaded with CRED form for creating new CPT is correct, even if I check it in Media.

function validate_featured_image_size( $field_data, $form_data ){
 
    $form_id = array( 292,488 );
 
    $target_width = 300;
    $target_height = 200;
 
    if ( in_array( $form_data['id'], $form_id ) ) {
 
        list( $fields,$errors ) = $field_data;
 
 		if (empty($fields['_featured_image']['value']))
        {
            $errors['_featured_image'] = 'Prosíme, nahrajte logo';
        }
		else {
			$check = getimagesize( $fields['_featured_image']['value'] );
			if ( $check !== false ) {
 
				$width = $check[0];
				$height = $check[1];
 
				if ( $width !== $target_width || $height !== $target_height ) {
					$errors['_featured_image'] = "Obrázek nemá uvedené rozměry";
				}
        	}
		}
		
        $field_data = array($fields,$errors);
    }
 
    return $field_data;
}
add_action( 'cred_form_validate', 'validate_featured_image_size', 10, 2 );

Hi, if you remove "-150x150" from the filename using str_replace, is the problem resolved?

function validate_featured_image_size( $field_data, $form_data ){
  
    $form_id = array( 292,488 );
  
    $target_width = 300;
    $target_height = 200;
  
    if ( in_array( $form_data['id'], $form_id ) ) {
  
        list( $fields,$errors ) = $field_data;
  
        if (empty($fields['_featured_image']['value']))
        {
            $errors['_featured_image'] = 'Prosíme, nahrajte logo';
        }
        else {
            $orig = str_replace('-150x150', '', $fields['_featured_image']['value']);
            $check = getimagesize( $orig );
            if ( $check !== false ) {
  
                $width = $check[0];
                $height = $check[1];
  
                if ( $width !== $target_width || $height !== $target_height ) {
                    $errors['_featured_image'] = "Obrázek nemá uvedené rozměry";
                }
            }
        }
         
        $field_data = array($fields,$errors);
    }
  
    return $field_data;
}
add_action( 'cred_form_validate', 'validate_featured_image_size', 10, 2 );
