Feature Request - Conditional Required

Something that seems to be coming up more and more is needing a way to make a field required, but only if another field is checked or has content.

For example, let's say we have the following fields:

  • Warranty Serviced (checkbox)
  • Date of Service (date/time)
  • Repair Type (dropdown)
  • Description (wysiwyg)

I want these three fields to be required ONLY if Warranty Serviced has been checked:

  • Date of Service (date/time)
  • Repair Type (dropdown)
  • Description (wysiwyg)

If Warranty Serviced has not been checked, then none of those fields would be required to have content.

What do you think?

Hi Kenny, 

You could do it with a plugin, check out the attached code.  

Give it a try and let me know any questions.  You'll need to make sure the tablename and field names match.

Hope that helps!

Amazing! This works perfectly!

I changed the name of the file and plugin so if I ever needed to add more than one it should work without conflict. However, shouldn't I just be able to add more tables / fields to this plugin? 

Thanks so much for putting this together.

Hi Kenny, 

Ok great, glad that's working!

Yes, could can just modify the code a bit to add additional tables.  Here's an example:

function conditionalErrorChecking($tableName, $recordExists, $oldRecord) {
    $errors = [];

    // table 1
    if ($tableName === 'your_table_here') {

        // conditional error checking rules
        $isWarrantyServiced = !empty($_REQUEST['warranty_serviced']);
        if ($isWarrantyServiced) {
            if (empty($_REQUEST['date_of_service:string'])) { // add :string prefix to date entire date string (if set)
                $errors[] = "Please fill out the date of service field.";
            }
            if (empty($_REQUEST['repair_type'])) {
                $errors[] = "Please fill out the repair type field.";
            }
            $wysiwygWithoutTagsOrWhitespace = trim(strip_tags($_REQUEST['description'] ?? ''));
            if (empty($wysiwygWithoutTagsOrWhitespace)) { // wysiwyg, remove all tags and check if empty after that
                $errors[] = "Please fill out the description type field.";
            }
        }
    }

    // table 2
    if ($tableName === 'another_table') {
        // error checking code goes here
    }

    // show errors
    if ($errors) {
        $errorsHTML = implode("\n", $errors);
        die($errorsHTML);
    }
}

I previously added some extra variables for readability, they're not strictly necessary.  

Let me know if you have any questions about how it works or how to add another table/field.
