This is the code I use and it didn't work:

add_filter('cred_form_validate','cred_filetype_size_validation',10,2);
function cred_filetype_size_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 (( 3850 == $form_data['id']) && (isset($_FILES['wpcf-addition-file']['size']))) {

//Retrieve file type
$file_type_uploaded=$_FILES['wpcf-addition-file']['type'];

//Retrieve file size
$file_size_uploaded=$_FILES['wpcf-addition-file']['size'];

//Validate files uploaded, make sure its PDF file type AND not more than 100kB
if (!$file_size_uploaded < 100) {

//Validation failed,
// set error message per field
//Remove wpcf - prefix here!
$errors['addition-file']='Sorry the file you have uploaded is not of correct type or exceeded size limit.';

}

}
//return result
return array($fields,$errors);
}

------------
3850 is the form ID and "addition-file" is the slug of the custom field

Hello,

I assume you are using default AJAX upload feature in your post form, if it is, please try another filter hook "cred_form_ajax_upload_validate":

https://toolset.com/documentation/programmer-reference/cred-api/#cred_form_ajax_upload_validate
This hook provides custom validation for files that are uploaded using AJAX

You can get the example codes by clicking link "Usage examples"

Hi I change the code to this but still not working, it still can upload the file size more than 100:

add_filter('cred_form_ajax_upload_validate','my_validation',10,2);
function my_validation($error_fields, $form_data)
{
//field data are field values and errors
list($fields,$errors)=$error_fields;
//validate if specific form
if ($form_data['id']== 3850)
{
//check if featured image exists o
if ($fields['wpcf-addition-file']['size'] > 100)
{
//set error message for featured image
$errors['addition-file'] = 'Wrong size image';
}
}
//return result
return array($fields,$errors);
}

PS: the field type I use is File

Hello,

Please try to modify your PHP codes as below:

add_filter('cred_form_ajax_upload_validate','my_validation',10,2);
function my_validation($error_fields, $form_data)
{
	//field data are field values and errors
	list($fields,$errors)=$error_fields;
	//validate if specific form
	if ($form_data['id']== 20)
	{
		//check if featured image exists o
		if ($fields['wpcf-addition-file']['field_data']['size'] > 100000)
		{
			//set error message for featured image
			$errors['addition-file'] = 'Wrong size image';
		}
	}
	//return result
	return array($fields,$errors);
}

And test again

Hi,
It solved the problem, but one more thing.
How can I remove the "addition-file" text in the alert message "addition-file: Wrong size image"?

[Luo Yang]

It is not recommended to remove it, but you can change the text, for example, change this line from:

$errors['addition-file'] = 'Wrong size image';

To:

$errors['error'] = 'Wrong size image';
