I have two groups of images (animals, and clothes).  When the image is clicked I want to get the value.    Eg. $animal = 2 (this mean that the dog image was clicked)

So after clicking I might have $animal = 2  $clothes = 1

<img src="images/cat.png" width="49" height="50" value="1"/><img src="images/dog.png" alt="" width="49" height="50" value="2" /><img src="images/cow.png" alt="" width="49" height="50" value="3" />
<img src="images/horse.png" alt="" width="49" height="50" value="4"/>

<img src="images/jumper.png" alt="" width="49" height="50" value ="1"/>
<img src="images/dress.png" alt="" width="49" height="50" value="2" />
<img src="images/jacket.png" alt="" width="49" height="50" value="3" />

<script type="text/javascript" src="http://85.159.69.158/mail/jq.js"></script>
<script>
	var animal ;
	var clothes ;
	function submitMe(){
		$.post('myphpfile.php',{animal : animal,clothes : clothes},function(reply){
				alert(reply);
		});	
	}
</script>
</head>

<body>
<img src="images/cat.png" width="49" height="50" value="1" onclick="animal = 1" />
<img src="images/dog.png" alt="" width="49" height="50" value="2" onclick="animal = 2" />
<img src="images/cow.png" alt="" width="49" height="50" value="3" onclick="animal = 3" />
<img src="images/horse.png" alt="" width="49" height="50" value="4"  onclick="animal = 4" />

<img src="images/jumper.png" alt="" width="49" height="50" value ="1"  onclick="clothes = 1" />
<img src="images/dress.png" alt="" width="49" height="50" value="2"  onclick="clothes = 2"  />
<img src="images/jacket.png" alt="" width="49" height="50" value="3" onclick="clothes = 3"/>
<input type="button" onclick="submitMe()" value="Sumit Me" />
</body>
</html>

Open in new window


Here is your myphpfile.php ;

 
<?php
	extract($_POST);
	echo $clothes."<br />" ;
	echo $animal ;
?>

Open in new window

for each img tag add onclick event function callMe and pass the value which you would like to get as follows

onclick=callMe("")

<img src="images/jumper.png" alt="" width="49" height="50" value ="1" onclick="callme('1')"/>
<img src="images/dress.png" alt="" width="49" height="50" value="2" onclick="callme('2')"/>
<img src="images/jacket.png" alt="" width="49" height="50" value="3" onclick="callme('3')"/>


writre javascript function
callMe(imgvalue){
//code which you want for these images....

}

As i understand he needs both values at the same time

So after clicking I might have $animal = 2  $clothes = 1

So using a kind of submit would be better instead of submitting onclick

Very for sorry for delay, missed your reply.  I was trying to test locally.  Do you have the code that is in the jq.js file?

Also does it need to save it to an external file Ali?

Debbie if you just copy and paste http://85.159.69.158/mail/jq.js in your address bar you can download it .

Yes saving jq.js as external file would be better .
