custom php validation not working in chronoforms

Hi Max,

I am using the latest version of Chronoform and somehow I am having trouble including a custom server side validation in the form. My custom php validation in the radio button is not working. If I can get the right input on how to use the php validation in the latest version, I will appreciate it. I am trying to validate if the radio button selected is equal to "Other" then the textbox should not be empty and vice versa but it is not working when I include the validation to the VAlidation tab/Enable Server side validation = Yes/Server side validation code. Below is my code for html and validation. Please advice how to write it if it is wrong. Thanks.

<div class="form_item">
  <div class="form_element cf_text"> <span class="cf_text">Please specify the amount of money you would like to give.</span> </div>
  <div class="cfclear"> </div>
</div>

<div class="form_item">
  <div class="form_element cf_radiobutton">
    <label class="cf_label" style="display: none;">Click Me to Edit</label>
    <div class="float_left">
      <input value="$25" title="" class="radio validate-one-required" id="radio00" name="radio0" type="radio" />
      <label for="radio00" class="radio_label">$25</label>
      
<input value="$50" title="" class="radio validate-one-required" id="radio01" name="radio0" type="radio" />
      <label for="radio01" class="radio_label">$50</label>
      
<input value="$100" title="" class="radio validate-one-required" id="radio02" name="radio0" type="radio" />
      <label for="radio02" class="radio_label">$100</label>
      
<input value="$250" title="" class="radio validate-one-required" id="radio03" name="radio0" type="radio" />
      <label for="radio03" class="radio_label">$250</label>
      
<input value="$500" title="" class="radio validate-one-required" id="radio04" name="radio0" type="radio" />
      <label for="radio04" class="radio_label">$500</label>
      
<input value="$750" title="" class="radio validate-one-required" id="radio05" name="radio0" type="radio" />
      <label for="radio05" class="radio_label">$750</label>
      
<input value="$750" title="" class="radio validate-one-required" id="radio06" name="radio0" type="radio" />
      <label for="radio06" class="radio_label">$750</label>
      <br />
   
<input value="Other" title="" class="radio validate-one-required" id="radio07" name="radio0" type="radio" />
      <label for="radio07" class="radio_label">Other</label>
      <label class="cf_label" style="display: none;">Click Me to Edit</label>
    <input class="cf_inputbox validate-currency-dollar" maxlength="150" size="30" title="Enter dollar amount here" id="text_7" name="donate_amount_other" type="text" />

    </div>
 
    
  </div>
</div>

Here is my custom php validation for the radio button and textbox.

<?php
$messages = array();
$radio0 = JRequest::getString('radio0', '', 'post');
if (!$radio0) {
     $messages[] = "One selection is required";
}
if ($_POST['radio0'] == 'Other') {
    if (empty($donate_amount_other)){
    return 'You selected Other, please enter amount to donate in the textbox to avoid errors';
} else {
   $_POST['radio0'] == 'Other';
}
}
//check if there are any error messages and return 
if(count$messages) ) {
   return implode('<br />', $messages);
}
?> 

I ham new in this version which is totally different from the 2.1 version because the php validation I included in the old version doesn't work here. Hope you can help me as soon as possible. Thanks.

Hi jmarian1,

You have the variable $donate_amount_other in the code but it isn't defined anywhere. Here's a modified version of the code:

<?php
$messages = array();
$radio0 = JRequest::getString('radio0', '', 'post');
$donate_amount_other = JRequest::getString('donate_amount_other', '', 'post');
if ( !$radio0 ) {
  $messages[] = "One selection is required";
} elseif ( $radio0 == 'Other' && !$donate_amount_other ) {
  $messages[] 'You selected Other, please enter amount to donate in the textbox to avoid errors';
}
//check if there are any error messages and return
if ( count$messages ) ) {
   return implode('<br />', $messages);
}
?>

Hi Bob,

Thanks for the revised version but somehow I tried your code and still the validation doesn't work. It still allow to go to the next step if Other is selected without the $$$ amount entered. I am not sure if there is something wrong with the code or the chronoform itself. Please advice. Thanks.

Hi Bob,

Thanks for the insight. SOmehow I manage to tweak the code and it works. Thanks again.😀
