Let's say I have a form and I am using gform_validation and the name advanced field(because I do) that is outputing
With my other custom validation i'm able to use $_POST[input_4_#]; but for some reason $_POST[input_4_2.3]; dosen't work.
Really all I want to do is not allow people to use numbers as their name. This should be a simple regex I just need to figure out how to get the Value of input 4_2.6 and 4_2.3.
Thanks
Hi Brooke,
$_POST keys for radio, checkboxes, and advanced fields containing multiple inputs will follow this format:
input_{field_id}_{input_index}
So if the field's name is "input_2.3", this could be access in the $_POST like this: $_POST['input_2_3'].
Thanks, that did the trick. I put in a feature request here http://www.gravityhelp.com/forums/topic/simple-custom-validation to request this process be simpler. I also have a quick question with custom validation like $form["fields"][4]["failed_validation"] = true; where does the [4] come from? I know that's where the validation shows up but it seems to be independent from field number. From what I've gathered it's the position of the field starting with 0 so 4 would be the 3rd input field. Is this correct?
