Post type Submit when radio button clicked

[RogerInHawaii]

I want to effectively do a Post type submit to the very same page when the user clicks on a particular radio button. Of course, I also want it to recognize the click (i.e. checkmarking the radio button) first so the new status of that readio button gets properly Posted.

How do I do that?

Heay, RogerInHawaii.

What you'll want to do is set the checked property of the radio button, then submit the form. You may also need to change the action of the form.

<form id="thePfhorm" action="somepage.php" method="post">
    <input type="radio" onclick="doClick(this);" />
</form>
 

function doClick(element) {
    element.checked = true;
    var pfhorm = document.getElementById('thePfhorm');
    pfhorm.action = location.href;
    pfhorm.submit();
}

pbmods,

Is there a way to do that with just PHP? Can the OnClick call a PHP function and then within the PHP fnction cause a submit to occur?

Or can the Onclick itself somehow specify a submit?

Heya, Roger.

Unfortunately, no. PHP and JavaScript cannot interact. Think about it like this: PHP is server-side, whereas JavaScript is client-side, and the only way to make a server request from JavaScript is (currently) to use AJAX.
