Jquery检查是否有东西在PHP中发布了$ _POST

Question

I haven't been able to find an answer to this that works. All I want to do is check with Jquery to see if something has been posted in PHP.

PHP:

if ($_POST['clockin'] == "Clock In") {  
    //some code
};

And for the Jquery:

if (<?php $_POST['clockin'] == "Clock In" ?>) {
        $("#clockin").click(function(){
            $(this).attr('disabled', 'disabled');
            $("#clockout").removeAttr('disabled');
        });
    };

Answer 1

Try this,

<?php if ( isset($_POST['clockin'])) { 
    if ( $_POST['clockin'] == "Clock In") { ?>
        $("#clockin").click(function(){
            $(this).attr('disabled', 'disabled');
            $("#clockout").removeAttr('disabled');
        });
<?php } } ?>

Make sure you enclose script with <script></script> tags.
