Im sure this has been discussed endless times but I can't find anything which will do it how I want to.
I want to seemlessly execute some PHP onclick. It will just update a row in MySQL and I dont want the user to be aware of this happening.
How would I do this?
Im a complete Javascript newbie by the way.
Im not sure if this is what you need. But this trick wil work in some cases.
Assuming that you have the following php function in your page
<html>
<head>
<title></title>
<?php
function changeBg() {
$bgColour = $_REQUEST['demo'];
if(!isset($bgColour)):
echo $bgColour;
else:
echo '#fff';
endif; }
echo '<style type="text/css">';
echo 'body { background-color: '.changeBg().'; }</style>';
?><script type="text/javascript">
<!--
function bcolor() {
var ua = (document.all) ? document.forms['myform'] : document.getElementById('myform');
try {
ua.demo.value = this.title;
if (ua.demo.value === this.title) {
return ua.submit(); }
else { window.location.href = "<?php echo $_SERVER['PHP_SELF']; ?>"; } } catch(e) { } }
//-->
</script>
</head>
<body>
<form id="myform" action="<?php echo $_SERVER['PHP_SELF']; ?>" metho="post">
<div>
<input type="hidden" name="demo" id="demo" />
</div>
</form>
<p>Change the background of this page to <a href="javascript:bcolor();" title="black">black</a>.</p>
</body>
