What is the best way to refresh a form without running through the validation process? - El Forum - 07-25-2012

[eluser]DocFunky![/eluser]
I'm setting up a cart where the user can update the quantity. Because I don't know aJAX to do it instantly, I'm looking to do it in full php with a refresh cart.( you can still se my post where I try to set it up with AJAX)

The thing is that there is a form below the cart and when the user change the quantity (into an input) he has to click on 'refresh' or 'recalculate', whatever.

So my problem is I get the validation process running as the re-calculate is like a submit button ( the price is calculated at the begining of the form method) because the user modified an input, and for all the fields that has not been filled yet, I got an error.

How can I say "If the user click on refresh, don't submit the form to the validation process, just take that input in consideration" ? I don't know if it is possible to have 2 separated forms on the same page ? (they are inside each other)

I give a part of my form, I need to listen to the

> form_dropdown('quantity'.$product['title'], $options,$value[$product['title']],$data0);

when I want to update the quantity, and only this one.

Code:
<ul class="form">
        <li>
         <h2>Your Information</h2>
        </li><li>
         <ul class="form" id="threeColumns">
          <li>
          &lt;?php
           echo form_open('main/Form');
          
           echo form_label('First Name', 'firstname');
           echo ' :</br>';
           if(set_value('firstname')){
            $valuefirstname= set_value('firstname');
           }else{
            $valuefirstname= $this->session->userdata('firstname');
           }
           echo form_input('firstname', $valuefirstname);
           echo form_error('firstname');
    
           echo '</li><li>';
          
           echo form_label('Last Name', 'lastname');
           echo ' :</br>';
           if(set_value('firstname')){
            $valuelastname= set_value('lastname');
           }else{
            $valuelastname= $this->session->userdata('lastname');
           }
           echo form_input('lastname', $valuelastname);
           echo form_error('lastname');
    
           echo '</li><li>';
          
           echo form_label('Email', 'email');
           echo ' :</br>';
           if(set_value('firstname')){
            $valueemail= set_value('email');
           }else{
            $valueemail= $this->session->userdata('email');
           }
           echo form_input('email', $valueemail);
           echo form_error('email');
          ?&gt;
          <div class="fError Right">
           &lt;?php if(ISSET($error) AND $error !=NULL)
             echo $error;
           ?&gt;

          </li>
         </ul>

               }else{

               }
               $data0 = 'class="quantSelect" value="'.$value[$product['title']].'" id="quant'.$product['title'].'"';
              
               echo  form_dropdown('quantity'.$product['title'], $options, $value[$product['title']],$data0);
