This thread is resolved. Here is a description of the problem and solution.
Problem:
The user would like to validate an image field(repeatable) in a Toolset form for the image type, size, dimensions, and number of images
Solution:
This will require custom code. Check this example code:
add_action('cred_form_validate', 'my_image_validation_func',10,2);
function my_image_validation_func($error_fields, $form_data) {
// all the valid file types
$file_types = array('image/jpeg','image/png','image/jpg');
$max_size = 5 * 1024 * 1024;
$forms = array( 1806 );
// Field data are field values and errors
list($fields,$errors)=$error_fields;
if (in_array($form_data['id'], $forms ) && (isset($_FILES['wpcf-book-images']['type']))) {
// 1. Minimum number of photos is '3'.
if ( count( $_FILES['wpcf-book-images']['name'] ) < 3 ) {
$errors['wpcf-book-images'] = 'Add at least 3 images';
return array( $fields, $errors );
}
// 2. Dimensions of the photo should be at least 350 (height) x 350 (width).
foreach ( $_FILES['wpcf-book-images']['tmp_name'] as $tmp_image ) {
$sizes = getimagesize( $tmp_image );
if ( $sizes[0] < 350 || $sizes[1] < 350 ) {
$errors['wpcf-book-images'] = 'An image is too small. Images should be at least 350x350';
return array( $fields, $errors );
}
}
// 3. The file types should be JPG, PNG and JPEG.
foreach ( $_FILES['wpcf-book-images']['type'] as $type ) {
if ( !in_array( $type, $file_types ) ) {
$errors['wpcf-book-images'] = 'Image file type is not supported: ' . $type;
return array( $fields, $errors );
}
}
// 4. Maximum file size should be 5MB.
foreach ( $_FILES['wpcf-book-images']['size'] as $size ) {
if ( $size >= $max_size ) {
$errors['wpcf-book-images'] = 'An Image is too big. Images should less than 5MB';
return array( $fields, $errors );
}
}
}
//return result
return array($fields,$errors);
}
