URGENT: form validation

**Atli** · Jul 31 '08, 08:16 PM

Are you calling the JavaScript function to check the fields after they have been submitted? That won't work. At that point there will be no fields to check.

Try attaching the JavaScript check function to the forms onsubmit event, or the submit buttons onclick event.

Also, the huge regex variable in your JavaScript code contains line-breaks, which is not allowed.

If the *Javascript* function isn't called, then this *isn't* a PHP problem.

Agreed. Moving to the JavaScript forum....

Now then.

Try adding an onsubmit handler to your form.

I am lost in this combination. I tried everything thing onsubmit() for form, action for form and onlick for submit button. Nothing worked at all except time waste. I alwasy prefer javascript for form validation but now...I dropped the idea to use javascript for php form validation, and used php-form-validation functions for this purpose. It took me a while to write that but that worked . If some want to post how i did that I'll be happy to do that.
Thanks All

please show how you tried to call the 'checkForm'-method on submit ... the validation must return a boolean value and the line should be similar to the following:

[CODE=html]<form name="my_form" onsubmit="retur n checkForm();"/>[/CODE]
kind regards

That was a big mistake in the first place. You should never depend on JavaScript validation alone. It's only there as a convenience to avoid unnecessary trips to the server. You MUST have server-side validation at all times.
