[SOLVED]Form Builder How to prevent submition if value exist

[blackhawk]

Within CMSMS 1.11.4, and Form Builder 0.7.3, I'm trying to setup the following condition for a specific input text field:

If the user fills out this specific field, then don't submit the form.

Is this conditional process possible within Form Builder? If so, how can I incorporate this?

Thanks for any advice!

Regex validation is possible on text input -> Advanced tab.

I will look into that. Thank you for the tip.

Velden, thanks for the feedback, but is there a JavaScript location built into Form Builder where we can validate submitted values before the submission is successful?

For example, if I have a text input field called animals, and someone wrote cat into that field, I could then detect the text value is 'cat' with JavaScript and then either cancel the submission process or do nothing. Where would the appropriate panel be located for this type of action in Form Builder?

Thanks!

Easy enough to do with jquery in the form template. something like:

Code: Select all

$('form').submit(function(e){
  var f = $(this).find('#YOURFIELDSID');
  if( typeof f != 'undefined' && $(f).val() != '' ) {
     alert('error message');
     $(e).preventDefault();
  }
});

I'm assuming that this is for spam prevention... If so, jQuery might not work that well.

Thank you calguy1000 for displaying how easy it is to integrate custom jQuery with Form Builder! That was a root question in the back of my mind, and you just confirmed it for me. Thanks!

Thank you Wishbone for that post. You're jedi powers read through my mind and that was exactly what I was looking for because I am note comfortable yet apply regular expression to form fields...I spend most of my day developing with javascript...

But anyway, thank you guys! I feel like I'm learning new stuff everyday! Cool.

I think Javascript is pretty useless for spam prevention this way.

I'd think spam bots just post their data the the form handler, so no javascript is involved at all.

Understood. Thanks for the good tip!
