jquery form submission help

**phantom007** · Jul 1, 2008, 01:49

Hi,

I am trying to run a simple jQuery script that would load a php page "load.php" on click of a submit button and the load.php page would return the value of "tname" variable which is "John" in this case.

Following is my jQuery script.

Code:

	<script src="jquery-1.2.6.js"></script>
<script>
$(document).ready(function(){

	$("form#myform").submit(function() {

		$.get("load.php", { tname: "John", ttime: "2pm" });
		$("#quote").load("load.php");
	return false;
	});

});

</script>

<div id="quote"></div>
<form method="post" id="myform">
<input name="submit" type="submit" value="Submit" />
</form>

load.php page script

PHP Code:


<?php

echo $_GET['tname'];

?>

However, the above does not work.

Can you help me plz?

Thanx

You need to set the form action attribute to "get" if you want it to work with ur PHP script.

Nvrmnd I see you're using the GET method in jQuery - Although, you will need to create a non-JS fallback.

You need to do something with the response data so:

Code JavaScript:

$.get("load.php", { tname: "John", ttime: "2pm" },function(data){
    $("#quote").append(data);
});

can u show me an example plz?

**JimmyP** · Jul 1, 2008, 02:18

? Look above?

**phantom007** · Jul 1, 2008, 02:35

in the load.php page, if I put the following code

PHP Code:




<?php



echo $_GET['tname']." There you go...";



?>

and use your code, then I just get the text "There you go..." and not the tname value. What am I missing?

Did you delete this line? -

Code JavaScript:

$("#quote").load("load.php");

**phantom007** · Jul 1, 2008, 03:04

Yes. still in vain.

**JimmyP** · Jul 1, 2008, 03:10

Weird... It works for me...

This is what I'm using:

Code html4strict:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>test</title>
<script type="text/javascript" src="jquery.js"></script>
</head>
<body>
<script type="text/javascript">
$(document).ready(function(){
    $("form#myform").submit(function() {
        $.get("load.php", { tname: "John", ttime: "2pm" },function(data){
            $("#quote").append(data);
        });
        return false;
    });
});
</script>
<div id="quote"></div>
<form method="post" id="myform">
<input name="submit" type="submit" value="Submit" />
</form>
</body>
</html>

PHP (load.php)

Code php:

<?php
echo $_GET['tname']." There you go...";
?>

Yes it works now.

Could u plz tell me what does this line mean?

Code:

$("#quote").load("load.php");

thanx for ur help.

**JimmyP** · Jul 1, 2008, 03:22

Well, all that line would do is load all the contents of "load.php" into #quote - So you could theoretically do this:

Code JavaScript:

$("#quote").load("http://www.google.com");

Although that would be pretty pointless.

You don't have to use $.get - you could do something like this:

Code JavaScript:

$("#quote").load("load.php?tname=john&ttime=2pm");

Using $.get is best though...

**phantom007** · Jul 1, 2008, 03:44

ahhh!!! gotcha.

Seems you are a JS expert.

Thanx for all your help.

**phantom007** · Jul 1, 2008, 22:03

Hi again

How do I do the same thing using $.post method?

Thanx

**JimmyP** · Jul 1, 2008, 22:53

Very simple, just change "get" to "post". ($.get --> $.post)

Also change it in your PHP script ($_GET --> $_POST)...

**phantom007** · Jul 1, 2008, 22:58

so do i still have to pass the parameters if its post or will it detect all the form variables automatically?

**JimmyP** · Jul 1, 2008, 23:19

It won't detect them - you could loop through them like shown in this screencast though: http://remysharp.com/wp-content/uplo...ajax_forms.mov

**JimmyP** · Jul 1, 2008, 23:19

If it's only a few fields adding them individually would probably be best...
