[Gelöst] Minimum Image size on upload

[Author]

Hi there,

We tried to implement the code for having a check for minimum upload size from this post:
https://toolset.com/forums/topic/set-the-minimum-resolution-of-image-upload/

This works fine for our create form but when we want to duplicate the code for the edit form as well it is causing a bug.

How can we use it to have the field 'logo-image' checked in both forms?

Thanks,

Paul

Hi Shane,

We used the code from the topic and adjusted it for our cred form for creating content:
https://toolset.com/forums/topic/set-the-minimum-resolution-of-image-upload/

When i duplicate this code for the cred-form to edit content (i only replaced the form id, the field name is the same in both forms) and place in my functions.php i get a white screen.

The way we placed the code:
Image size CE form - Create

add_filter('cred_form_validate_4483', 'cred_image_resolution_validation',10,2);

function cred_image_resolution_validation( $field_data, $form_data ) {
// Field data are field values and errors
	list( $fields, $errors ) = $field_data;
//Run the rest of code for this CRED ONLY and IF the file is upload type and size are set.
	if ( ( 4483 == $form_data['id'] ) && ( isset( $_FILES['wpcf-ce-logo']['tmp_name'] ) ) ) {
		$check = getimagesize( $_FILES['wpcf-ce-logo']['tmp_name'] );

		if ( $check !== false ) {
			$awidth  = $check[0];
			$aheight = $check[1];
			if ( ($width < 300) && ($height < 300) ) {
				$errors['ce-logo'] = 'Sorry, too small image.';
			}
		} else {
			$errors['ce-logo'] = 'Sorry this is not a valid image file.';
		}
	}

	return array( $fields, $errors );
}
>>

Image size CE form - Edit

add_filter('cred_form_validate_4459', 'cred_image_resolution_validation',10,2);

function cred_image_resolution_validation( $field_data, $form_data ) {
// Field data are field values and errors
	list( $fields, $errors ) = $field_data;
//Run the rest of code for this CRED ONLY and IF the file is upload type and size are set.
	if ( ( 4459 == $form_data['id'] ) && ( isset( $_FILES['wpcf-ce-logo']['tmp_name'] ) ) ) {
		$check = getimagesize( $_FILES["wpcf-ce-logo"]["tmp_name"] );

		if ( $check !== false ) {
			$width  = $check[0];
			$height = $check[1];

			if ( $width < 300 && $height < 300 ) {
				$errors['ce-logo'] = 'Sorry, too small image.';
			}
		} else {
			$errors['ce-logo'] = 'Sorry this is not a valid image file.';
		}
	}

	return array( $fields, $errors );
}

Hope this makes it more clear.
Thanks,

Paul

Hi Paul,

Thanks for sharing the code.

However I see that you say you are getting a white screen, in this case I would like for you to enable the wordpress debugging in order for us to see the error reports of what is causing the white screen.

Once you have done this please let me know the error that is being displayed.

Thanks,

Hi Paul,

So the issue is being caused by a duplicate function name.

To fix this all you need to do is change the function name of one of the functions so it can be unique.

/*** Image size CE form - Edit ***/
add_filter('cred_form_validate_4459', 'cred_image_resolution_validation2',10,2);
function cred_image_resolution_validation2($field_data, $form_data)
{
// Field data are field values and errors
list($fields,$errors)=$field_data;
//Run the rest of code for this CRED ONLY and IF the file is upload type and size are set.
if (( 4459 == $form_data['id']) && (isset($_FILES['wpcf-ce-logo']['tmp_name']))) {
$check = getimagesize($_FILES["wpcf-ce-logo"]["tmp_name"]);

if($check !== false) {
$width = $check[0];
$height = $check[1];

if($width < 300 && $height < 300) { $errors['ce-logo'] = 'Sorry, too small image.'; } } else { $errors['ce-logo'] = 'Sorry this is not a valid image file.'; } }return array($fields,$errors); }

/*** END ***/

Please try the code above and it should work.
