Pass parameter to Joomla.submitbutton(task)

Question

I've my custom task = request.state

in my controller, I've code like

public function state($param)
{
     //Do my task
}

My question is how do I pass $param to

Joomla.submitbutton(request.state)

Answer 1

In general you override Joomla.submitbutton in your view's php file, set a hidden fields value to the request parameter you wish to send, then finally submit the form.

So say your admin view's template has a field

<input type="hidden" id="myinfo" value="" >

Then you would add some JavaScript to the view's template:

<script type="text/javascript">
Joomla.submitbutton = function(task) {
    jQuery('#myInfo').val('my custom value');
    Joomla.submitform(task, jQuery('#adminForm'));
}
</script>

Then your request's $_POST array will have

[myInfo] => 'my custom value'

@Rob - Thank you very much for your help. However, your method did not work for me. Here's how I made it work:

In my view layout file (default.php):

I added one hidden state field with blank code:

<input type="hidden" name="state" value="" />

In my JS file I added following code:

$('#cancel-request').click(function () {
if (confirm("Are you sure?"))
            {
                $("input[name='state']").val('cancel');
                Joomla.submitbutton('request.state');
            }
            else
            {
                return false;
            }
}

In my controller, I added following code:

public function state()
{
     $state = $this->input->post->get('state', '');
     // based on $state I made my code.
}
