Hello Nigel

I notice that users of the website sometimes upload far too small images, as a result, the pages do not look good.
So I tried to set a minimum height and width for the featured image, so that an image that is too small is rejected.
As help I used the ticket below, I have adjusted the ID number in the code to the ID number of the form of my site, but it doesn't work in some way.

The Form ID number is: 349
The minimum width should be: 500 px x 300 px

Would you like to take a look and help me?

The code I add to functions.php

function validate_featured_image_size( $field_data, $form_data ){

$form_id = array( 349 ); // add IDs of CRED forms

$target_width = 500; // Edit
$target_height = 300; // Edit

if ( in_array( $form_data['id'], $form_id ) ) {

// Split field data into field values and errors
list( $fields,$errors ) = $field_data;

$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'] = "Image wrong size";
}
}

$field_data = array($fields,$errors);
}

return $field_data;
}
add_action( 'cred_form_validate', 'validate_featured_image_size', 10, 2 );

Hello,

I suggest you try these:
1) Edit the post form, in section "Settings", enable option "Use the WordPress Media Library manager for image, video, audio, or file fields"
2) Follow our document to use another filter hook "cred_form_ajax_upload_validate" to do the image validation:
https://toolset.com/documentation/programmer-reference/cred-api/#cred_form_ajax_upload_validate

See the solution of another similar thread here:

For your reference.
