1. I don't believe Javascript can access the query string part of a URL. 

2. What?

There are only a few things I can think of to even get the URL in JQuery, let alone get data from it. Perhaps you can somehow modify this:

<!-- Full URL http://domain.com/file.whatever?anyvar=something -->

<script type="text/javascript">
alert($(location).attr('href'));
</script>

 

Your second question however makes no sense. I assume you want to access php sessions in your JQuery? In which case it should work just putting in the source code.

 

<?php
session_start();
$_SESSION['uid'] = "23123";
?>

<!-- other stuff -->

<script type="text/javascript">
<?php
echo "var stuff= '".$_SESSION['uid']. "';";
?>
alert('Err...hi? '+stuff+' ');
</script>

Situation:

i have 2 mysql table`s

1. tbl_document (id, number_of_document)

2. tbl_items_of_document (id, name_of_item, document_id, user_id)

 

now, clasic php html form

 

<form action="insert.php?document_id=<?php echo $id; ?>" method="post">
.....
</form>

 

after form we use

 

$document_id = $_GET["document_id"];
$name = $_POST["name_of_item"];
//...
mysql_query("INSERT INTO `tbl_items_of_document` SET `name_of_item` = '$name', `document_id` = '$document_id', `user_id` = '$user_id'")or die(mysql_error());

 

we have all necessary data inserted in the table

 

And the we come to problem if we want to use jquery

 

with code below, i can insert data in one independet mysql table

jQuery Basics: POST/GET Data (HTTP Request)

 

index.php

[/size][/font][/color]
<input type="text" id="name" />
<div id="name_feedback"></div>
[color=#000000][font=Tahoma, Verdana, Arial][size=3]

 

jfunc.js

[/size][/font][/color]
$('#name').keyup(function(){
var name = $('#name').val();
$.post('proces.php'), {name:name}, function(data) {
$('#name_feedback').html(data);
});

});
[color=#000000][font=Tahoma, Verdana, Arial][size=3]

 

proces.php

[/size][/font][/color]
<?php
if(isset($_POST['name'])){
$name = $_POST['name'];
echo $name; //or mysql_query.....
[color=#000000][font=Tahoma, Verdana, Arial][size=3]

 

and this code is ok for insert into independent table

 

what if we have relation database, with two tables?

1. tbl_document (id, number_of_document)

2. tbl_items_of_document (id, name_of_item, document_id, user_id)

 

and i want to insert data into tbl_items_of_document, and i nead for that:

- value of `id` from tbl_document

- and value of `session`

 

how to GET `id` of the document to write in to `tbl_items_of_document` with jQuery,

or,

how to GET session id with jquery, becose i want to know who create that item or item`s?

 

thanks

Everything on your proces.php will run. So, why not assign your session id into a variable on proces.php?

 

$session_id = $_SESSION['id'];

 

Of course you would also need a session_start();

FYI you can access the query string in Javascript using the window.location.search property.

My bad, I was thinking of the # part I think? Who knows.

window.location.hash

Hmmm now I'm wondering what it was that I couldn't use JS for that one time....

This function will do it for you:

function getGet(name)
   {
       var regexS, regex, results;

       name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
       regexS = "[\\?&]" + name + "=([^]*)";
       regex = new RegExp(regexS);
       results = regex.exec(documentSrc);

       if(results !== null)
       {
           return decodeURIComponent(results[1].replace(/\+/g, " "));
       }

       return false;
   }

 

So if your URL is www.example.com?key=value, you can get $_GET['key'] using:

getGet(key);
