Custom Validation ChronoForms V5

Hello,

I would like to perform some custom validations with ChronoForms v5.
I am willing to buy a good manual or even faq.
The first validation is to check if a username is valid.

The other is to check whether an integer that is entered is 11digits length. I do not have much experience with JavaScript so this is the code that I have created to do that. Can somebody help?

function customCheck(number11){
  if ( !number11.value.test.length()!=11) {
    el.errors.push("Your number must be 11 digits");
      return false;
  } else {
    return true;
  }
}

Thanks a lot.

Hi hellykun,

Please check the custom validation box info under the validation tab in v5 rc4.1, its explained how to write a custom function in v5, you can then write your function name there and it will be used.

Ok just something simpler.

I have created a filed number for example.

I have added as customValidation with the name "customCheck"

Then in the onload Event before everything else I have added a Load Javascript block.
Inside the block I have added my function:

function customCheck(number){
  if (number < 20) {
      return false;
  } else {
    return true;
  }
}

Am I doing something wrong? Nothing different happened.

Thanks a lot in advance.

Hi hellykun,

I think that what is passed to the custom function is the whole form element, not just it's value (see Max's example). Try changing your code to

if (number.value < 20) {

or possible

if (parseInt(number.value) < 20) {

to force it to an integer instead of a string.

Thanks a lot GreyHead.
The problem was not only that but the el.push.message is not receiving the correct message so I thought it was not registering at all.

Is there a way of adding custom PHP Server validation to Chronoforms V5. It is not possible for me to go to V4 only for this feature. Can I change a specific php file to achieve this?

Thanks a lot.

HI hellykun,

I'm afraid that so far I know nothing about the CFv5 code and what can (or can't) be changed :-(

Hi,

The code above is a javascript validation, if you need php server validation then simply use the "server side validation" action for auto validation, or the "Event switcher" action for custom stuff.

Thanks a lot.
Is there a guide on how to use the Event Swicher action because it is not so straightforward for me?
Because the validation I want to use is more complex than the predifined values of Server Side Validation.

Thanks a lot again.

Hi hellykun,

It's easy to use, just write your PHP code and make it return a string matching the event name you need to process, so suppose that you have 1 event in the event switcher called "test", then the code below will execute this event:

<?php
if(true){
return "test";
}

Thanks a lot admin, so how can I return stop submission of the form and show a message?

return false?

Just in case I would be nice if you can add a step by step tutorial for creating custom validation with php code because it is of high importance. If I succeed I will post it.

We will try to add more FAQs soon!

You can simply return "stop", and drag a "Show stopper" action in the "stop" event created using the "Event switcher".

Before that "show stopper" you may also add a "thanks message" action.

Thanks a lot admin!
I have added a custom validation rule by changing both chronoforms and joomla php files because it seemed easier to me.
