Create "Static" Field Names?

    Hi,

    I am writing a plugin to post-process form data using a gform_after_submission hook.

    I am after several specific fields that will appear across multiple forms (but not always in the same placement)

    Is there any way (during form creation) to create a field name/ID to be a static value that the plugin can always find, so that it does not need to be updated every-time a new form is added (or changed)

    As an Example, the phone number of this form is the first field, but on other forms it it the 3rd field & 11th field. I'd like to use the same line of code to get all of them regardless of the field position.
    $phoneNum = ($_POST['input_1']);

    hope this makes sense.

    Thanks!
    -Ed

  3. The field names are dynamically created for each form. I don't think it would be possible to assign static names. So, we need another approach.

    If you want to apply some processing to all forms, you can assign a custom CSS class in the form builder. Then, you can process any field with that specific CSS class. Here are a couple of snippets you can incorporate into your function.

    This will look through your form for any field with the custom CSS class my_class and apply your processing to that field:

    [php]
    if(strpos($field['cssClass'], 'my_class') === true) {
    // process this field
    }

    and

    [php]
    if($field['type'] = 'select') { // or whatever TYPE of field you want to process
    // process this field
    }

    You can combine them as well, like this:

    [php]
    if($field['type'] = 'select' && (strpos($field['cssClass'], 'my_class') === true)) {
    // process this field
    }

    Here's an example of looping through all the fields in a form, to see how it works:

    You would be using the same process with gform_after_submission rather than gform_pre_render.

    Also, gform_after_submission is available in 1.6 and later, so be sure you're using the latest release candidate.

    Thanks, Chris.

    I had thought about using the CSS as a workaround, but then they (might) complicate the UI.

    Would it be possible in a future update to allow an advanced option to set either the field name or ID? (or does GF really use both for processing)?

    Thanks again,
