Tell us what you are trying to do?

I would like to validate the file type of a file uploaded using Form CRED. Only PDFs should be allowed.
For images I would like to validate only images that are larger than 85 KB and smaller than 1024 KB

Post Form:
Name: Job-Form einfuegen
slug: job-form-einfuegen
Form ID: 375

Custom Field for PDF (File):
Name: Testpdf;
Slug: testpdf

Custom Field for image (Image):
Name: Testimage
Slug: testimage

Is there any documentation that you are following?

Thanks in advance for your help.

Hello,

How do you setup the post form?
If you are using the option "Use the WordPress Media Library manager for image, video, audio, or file fields", you can use filter hook "cred_form_ajax_upload_validate":
https://toolset.com/documentation/programmer-reference/cred-api/#cred_form_ajax_upload_validate

If you are not using that option, you will need to use another filter hook: "cred_form_validate":

Hi Luo, Thanks for the reply.

I´m using the option "Use the WordPress Media Library manager for image, video, audio, or file fields", witn filter hook "cred_form_ajax_upload_validate":

<?php
/**
* New custom code snippet (replace this with snippet description).
*/

toolset_snippet_security_check() or die( 'Direct access is not allowed' );

// Put the code of your snippet below this comment.
//Limit the upload file type PDF and size for the custom field.
add_filter('cred_form_ajax_upload_validate','wpbd_member_form_validation',10,2);
function wpbd_member_form_validation ($error_fields, $form_data)
{
//field data are field values and errors
list($fields,$errors)=$error_fields;
//validate if specific form
if ($form_data['id'] == 375)
{
//check image size
if ($fields['wpcf-testimage']['field_data']['size'] > 85 * 1024)
{
//set error message
$errors['wpcf-testimage'] = 'Wrong image size!';
}

if ( ($fields['wpcf-testpdf']['field_data']['size'] > 55 * 1024) || ($fields['wpcf-testpdf']['field_data']['type'] != 'application/pdf') )
{
//set error message
$errors['wpcf-testpdf'] = 'Wrong size Or document type! only pdf allowed!';
}
}
//return result
return array($fields,$errors);
}

I did some tests in the "testpdf field" with Image files and Word files, but the Form did not block the sending of the files.
Where am I wrong? can you help me please?.

Thanks in advance for your help.

Luo is on vacation. This is Minesh here and I'll take care of this ticket. Hope this is OK.

Instead of "cred_form_ajax_upload_validate" hook what if you try to use the "cred_form_validate" hook.

For example:

add_filter('cred_form_validate','func_cred_filetype_validation',10,2);
function func_cred_filetype_validation($error_fields, $form_data) {
    //field data are field values and errors
    list($fields,$errors)=$error_fields;
    //validate if specific form
    if ( $form_data['id']==375 ) {
            //check image size
if ($fields['wpcf-testimage']['field_data']['size'] > 85 * 1024)  {
//set error message
$errors['wpcf-testimage'] = 'Wrong image size!';
}

if ( ($fields['wpcf-testpdf']['field_data']['size'] > (55 * 1024) ) || ($fields['wpcf-testpdf']['field_data']['type'] != 'application/pdf') ) {
//set error message
$errors['wpcf-testpdf'] = 'Wrong size Or document type! only pdf allowed!';
}
    }
    //return result
    return array($fields,$errors);
}

Does that helps?
