This thread is resolved. Here is a description of the problem and solution.
Problem:
Validate custom upload fields in CRED.
Solution:
In order for custom upload fields to be validated with CRED you will need to ensure that AJAX upload is enabled for this form. This means that you form uses the wordpress media gallery to upload its files.
Once this is enabled then the code below should allow you to validate your uploaded files.
// For the resource file upload - check that the file is a PDF under 1MB in size.
add_filter('cred_form_ajax_upload_validate','cred_filetype_size_validation',10,2);
function cred_filetype_size_validation($error_fields, $form_data)
{
//field data are field values and errors
list($fields,$errors)=$error_fields;
//validate if specific form
if ( ($form_data['id']==5050) || ($form_data['id']==846) )
{
if(isset($fields['wpcf-produktovy-list'])) {
//Retrieve file type
$file_type_uploaded=$fields['wpcf-produktovy-list']['field_data']['type'];
//Retrieve file size
$file_size_uploaded=$fields['wpcf-produktovy-list']['field_data']['size'];
//check if featured image exists
if ( ($file_size_uploaded > 1000000) || ($file_type_uploaded != 'application/pdf') )
{
//set error message for featured image
$errors['produktovy-list'] = 'Sorry the file you have uploaded is not of correct type (PDF) or exceeded 1MB limit';
}
}
}
//return result
return array($fields,$errors);
}

Hi,
i follow this ticket for creating validation PDF, but i cannot figure out why it still takes other types of file.
https://toolset.com/forums/topic/cred-maximum-upload-size-for-file-type-field/
CRED FORM for logged users where i want to apply this validation - Edit form Řešení (ID: 5050)
Edit cred form settings:
Set this post status: Keep original status
Form submit: Submit this form without reloading the page (use AJAX)
After visitors Submit this form: Keep displaying form
I added this code to functions.php
// For the resource file upload - check that the file is a PDF under 1MB in size.
add_filter('cred_form_ajax_upload_validate','cred_filetype_size_validation',10,2);
function cred_filetype_size_validation($error_fields, $form_data)
{
//field data are field values and errors
list($fields,$errors)=$error_fields;
//validate if specific form
if ( ($form_data['id']==5050) || ($form_data['id']==846) )
{
if(isset($fields['wpcf-produktovy-list'])) {
//Retrieve file type
$file_type_uploaded=$fields['wpcf-produktovy-list']['field_data']['type'];
//Retrieve file size
$file_size_uploaded=$fields['wpcf-produktovy-list']['field_data']['size'];
//check if featured image exists
if ( ($file_size_uploaded > 1000000) || ($file_type_uploaded != 'application/pdf') )
{
//set error message for featured image
$errors['produktovy-list'] = 'Sorry the file you have uploaded is not of correct type (PDF) or exceeded 1MB limit';
}
}
}
//return result
return array($fields,$errors);
}
Thank you for help
