Updating database with php and ajax

Question

Below is my script that updates my characters position in my database:

<script language="javascript" type="text/javascript">
function positionUpdate(){
var word = document.getElementById('test').value;
var queryString = "?word=" + word;
ajaxRequest.open("GET", "new_position.php" + queryString, true);
ajaxRequest.send(null);
alert(queryString);
}
</script>

Next is the script that tells the above script to run but I need to send two variables across to it so it knows what to update.

<a onClick="positionUpdate();"><img src="images/transparent.gif" border="0" /></a>

The link above is used multiple times so I need to send the values with that and not put the variables in the script at the top otherwise they would always be the same.

As a note I am using the php GET function to retrieve the variables in position_update.php

Thanks, tanni

Answer 1

Try:

<script language="javascript" type="text/javascript">
function positionUpdate(var1, var2){
    var word = document.getElementById('test').value;
    var queryString = "?word=" + word + "&var1=" + var1 + "&var2=" + var2;
    ajaxRequest.open("GET", "new_position.php" + queryString, true);
    ajaxRequest.send(null);
    alert(queryString);
}
</script>

and

<a onClick="positionUpdate('val1', 'val2');"><img src="images/transparent.gif" border="0" /></a>

Is that what you mean? It seems like a fairly basic question...

Answer 2

I don't understand your question.

Why don't you just pass the variables as function parameters to positionUpdate?

Maybe you could explain in a bit more detail what you are trying to accomplish.
