Form submission: Runs automatically when submit button hasn't been pressed

[halben]

I have the following: 

.. This is the button with hidden type ..

<input type="hidden" name="s2member_pro_paypal_registration[nonce]" id="s2member-pro-paypal-registration-nonce" value="xxx">
<input type="hidden" name="s2p-option" value="">
<input type="submit" name="r_submit" id="s2member-pro-paypal-registration-submit" class="s2member-pro-paypal-submit s2member-pro-paypal-registration-submit" value="Register" tabindex="1000">

My code to detect the submit button:

if (!isset($_POST['r_submit']) && $_POST['s2member_pro_paypal_registration']['nonce'] == 'xxx') {
    // Do nothing
} else {
    var_dump($something);
    // Do something
}

My site spits out 

var_dump()

 automatically when the form hasn't been submitted yet and I'm not sure why.

 

Can someone please help me?

 

Thanks,

Hal

If $_POST['r_submit'] is set or $other_post == $x then do nothing.

 

I think you want to use OR (||) rather than AND (&&).

I tried using

OR (||)

and it doesn't work. Any more suggestions?

Figured it out. I had to use the hidden type instead of the button name. It's weird. For the plugin, I had to custom insert a button name value so when the submit button has been pressed, it could read it. But for some reason, it wasn't reading the name value from the button.

 

Thanks for helping.
