Problem Passing AJAX Parameters to PHP

[millercj]

Running an Ajax script and the number of parameters i'm passing is dynamic. My parameter string is generated and sent to the PHP via the following function:

 

function save(numStd){

//Find Selected Class
var all = document.all ? document.all :
document.getElementsByTagName('*');
var elements = new Array();
for (var e = 0; e < all.length; e++)
if (all[e].className == 'active')
var currentClass=all[e].id; 

var sendParams=escape(numStd)+"&param1="+escape(currentClass);
var paramCounter=2

for(var i = 1; i <= numStd; i++){
window['lNameSave'+i] = document.getElementById("LastName"+i).value;
window['fNameSave'+i] = document.getElementById("FirstName"+i).value;
window['ageSave'+i] = document.getElementById("Age"+i).value;

sendParams =sendParams+"&param"+paramCounter+"='"+escape(window['lNameSave'+i])+"'";
paramCounter++;
sendParams =sendParams+"&param"+paramCounter+"='"+escape(window['fNameSave'+i])+"'";
paramCounter++;
sendParams=sendParams+"&param"+paramCounter+"="+escape(window['ageSave'+i]);
paramCounter++;

}
var urlNewStd = "/phpscripts/saveNewStd.php?param=";
http.open("GET", urlNewStd + sendParams, true);
document.getElementById("studentresult").innerHTML="<img src='/images/ajax-loader.gif' style='margin:50px 0 0 110px;'/>";
http.onreadystatechange = handleHttpResponseNewStd;
http.send(null);
}

 

 

if I input two records to send as parameters this is an example of what urlNewStd + sendParams looks like:

/phpscripts/saveNewStd.php?param=2&param1=4A&param2='Williams'&param3='Robin'&param4=55&param5='Moore'&param6='Demi'&param7=45

 

once it is in the PHP I can only access the first parameter which in the example would be "2"

 

I'm trying the get the Parameters in PHP via:

$variable= urldecode($_GET['param1']);

 

any ideas?

What is the problem?

[millercj]

I can only access the first parameter, none of the other ones have a value

[DeanWhitehouse]

that code doesn't make sense to me, you are sending each var on it's own instead of sending them all together.

 

Take a look at

lol your making it wayyyyyyyyyyyy to complicated with all the params, this is the wrong section btw.

[millercj]

how would you propose it's done?

Depends on what I'm using it for. As stated your script doesn't send the params all at once

What the interface is--is a window in which the user can add students to respective classes. The user creates as many "new student" fields (first name, last name, age) as they wish by clicking a button that number of times (so the number of parameters needed is dynamic). Then then the data in those fields needs to be passed via ajax to be inserted into a sql table.
