This thread is resolved. Here is a description of the problem and solution.
Problem:
Client is using the Forms cred_form_ajax_upload_validate hook to restrict the acceptable file types that can be uploaded for a file custom field, but it is not working, the accepted file types are being rejected.
Solution:
Their code wrongly defines the file types which do not match the file type reported by the global $_FILES object used for the test (e.g. they are testing for "application/text" instead of "text/plain".

I am trying to: Restricting File Types on File Upload CRED Field
Link to a page where the issue can be seen: hidden link
I expected to see: be able to upload files based on the code below
Instead, I got: error message from generated by the code
I used the code available at https://toolset.com/forums/topic/having-problem-with-restricting-file-types-on-file-upload-cred-field/ and modify it to the following:
//*Validate for csv xsl txt on File Upload
add_filter('cred_form_ajax_upload_validate','cred_filetype_validation',10,2);
function cred_filetype_validation($error_fields, $form_data)
{
$file_types = array('application/csv','application/xls','application/txt');
// Field data are field values and errors
list($fields,$errors)=$error_fields;
//Run the rest of code for this CRED ONLY and IF the file is upload type and size are set.
if (in_array($form_data['id'], [386]) && (isset($_FILES['wpcf-u-sngl-portfolio-file']['type']))) {
//Retrieve file type
$file_type_uploaded=$_FILES['wpcf-u-sngl-portfolio-file']['type'];
//Validate files uploaded, make sure its PDF file type
if (!in_array($file_type_uploaded, $file_types) ) {
//Validation failed,
// set error message per field
//Remove wpcf - prefix here!
$errors['File-Format-Error']='Sorry the file you have uploaded is not of the correct type. Accepted file types: csv, xls, txt';
}
}
//return result
return array($fields,$errors);
}
i modified the code to except csv, xls, and txt file formats
when i try to upload a file with one of the exceptions csv, xls, or txt i still get the error that the file extension is not excepted.
please advise,
thanks,
David
