Question

I’ve got the following Codeigniter code to display a form, with two image submit buttons. I need to know which button has been clicked by the user. Normally I just reference the name or value that is passed through, but nothing is passed from these buttons. All other fields/textboxes etc.. on the form pass through ok, but nothing from these buttons….

…. what am i missing? I’ve been pondering this for a couple of hours and no help from the net either!

<? 
            $attributes = array('id' => 'formname','name' => 'formname');
            echo form_open('processform',$attributes); 
            $btn_input = array(
                'subtype'   => ''
            );
            echo form_hidden($btn_input);

            $btn_search = array(
                'type'  => 'image',
                'src'       => '/graphics/button1.gif',
                'id'        => 'button1',
                'name'  => 'button1',
                'value' => 'button1'
            );
            ?>
            <div id='1stbutton' style='text-align: center'>
                <? echo form_input($btn_search);?>
            </div> 

            <?
            $btn_search = array(
                'type'  => 'image',
                'src'       => '/graphics/button2.gif',
                'id'        => 'button2',
                'name'  => 'button2',
                'value' => 'button2'
            );
            ?>
            <div id='2ndbutton' style='text-align: center'>
                <? echo form_input($btn_search);?>
            </div>

            <? echo form_close(); ?>

I had a similar issue (with Zend though)!
The thing is, the browser does not pass the “value” when input type=image.
to check wich button was clicked you could still reference the button by adding “_x” or “_y” to your button name (Ex ‘Button2_x’)and check the $_Post array against this.

if(isset($_POST['button2_x']))
{
  //button2 was clicked! 
}
else if(isset($_POST['button1_x']))
{
  //button1 was clicked go on!
}
