Question

I need to have a toggle button where …

JQuery and Php needed here?

If I click it one…the input hidden will be:

// Display this one if $myPhpVar isset
<input type="hidden" name="myHidden" id="myHidden" value="<?php echo $myPhpVar ?>" /> 

and if I click again:

// Display this one if $myPhpVar is not empty
<input type="hidden" name="myHidden" id="myHidden" value="" /> 

Hope I’ve explaining properly.

UPDATE: What I want to do is that If $myVar is not empty when I click button X then it will set the value to blank.

Here you go :

var phpvar = "<? php echo $myPhpVar ?>";

$('#myButton').toggle(function() {
$('myHidden').val(phpvar);
} ,function() {
$('myHidden').val('');
});
