Problem: I would like to enforce file type restrictions on a file upload field in a Form, but the cred_form_validate hook does not provide any information about the file uploads.

Solution: Use the cred_file_upload_disable_progress_bar hook to inspect AJAX file uploads. Inspect the $_FILES superglobal to retrieve file metadata.

//*Validate for PDF 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/pdf','image/jpeg','image/png','image/tiff','image/gif');
     
     
    // 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($form_data['id'], [654,836,848]) && (isset($_FILES['wpcf-pedigree']['type']))) {
       
            //Retrieve file type
            $file_type_uploaded=$_FILES['wpcf-pedigree']['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['pedigree']='Sorry the file you have uploaded is not of the correct type. Accepted file types: pdf, jpg, gif, png, tiff';   
                      
            } 
       
        }
    //return result
    return array($fields,$errors);
}

Problem:

In a CRED form for creating post, We initially had a post taxonomy term select field that was automatically populated based on the page it was on. These industry pages were given the same custom taxonomy we created for the CPT post that was to be created from these forms, and assigned the appropriate taxonomy term to match the term the post needed to go to. The idea was that the user shouldn't have to worry about selecting an option from a "Choose Industry" field when they're already on a page designating the industry they're interested in.

We had it working, but for whatever reason it no longer is, so I'm wondering if there was a PHP solution that I could utilize for this case.

Solution:

There isn't such a built-in feature within CRED forms, see our document:

https://toolset.com/documentation/user-guides/cred-shortcodes/#cred_field

The argument "value" works only for custom field in CRED form, it does not work for the taxonomy field.

As a workaround, you can setup a generic field in the CRED form to replace the taxonomy field:

https://toolset.com/documentation/user-guides/cred-shortcodes/#cred_generic_field

When user submit the CRED form, you can use CRED action hook "cred_save_data" to trigger a PHP function, and save the "industry" value into database, see documents:

https://toolset.com/documentation/programmer-reference/cred-api/#cred_save_data

This hook allows doing a custom action when post data is saved to database.

Relates an object (post, link etc) to a term and taxonomy type
