Insert the contents of the data from the previous page into the form that posts to the next page, in the form of <input type="hidden" name="foo" value="bar" />. Then, pull it out of the $_POST array on the next page.
About the <select> element returning NULLs, try specifying the name attribute on the <select> element, and a value attribute on each of the <option> elements. Don't forget to have one with the selected="selected" attribute set, to specify a default.

I have a table that were listed using looping from mysql database. In column edit i had a textbox and edit button. I want to post the value of the text box when user click edit button.My problem is when i click the edit button the value in the post take the value of last one(which group name = QW).
when i click the edit button the value in the post take the value of last one(which group name = QW).
So give them unique names.
Probably ones which incorporate the row number in the database.
e.g.
name="foo[row_number]"
… which will then let you loop over $_POST['foo'] as an associative array.

You should add onchange event for the first element and in the onchange handler call an ajax call. In the success handler populate the second dropdown element.

You can use cc[] as the name and in PHP your going to receive an array with all the info.
Or maybe you can just append a number after each name and interate them to read all results.
<select name="cc[]">...options...</select>
<select name="cc[]">...options...</select>
<select name="cc[]">...options...</select>
then in PHP $_POST['cc'] should be an array with all the selected options.

You can use array for while creating rows, use name for your each row's input field as array and when you submit the your form loop over your checkbox array and get the values from other elements using the same key which selected checkbox is having
I get the script for selecting the previous selected value in list box from Jquery get the pervious selected value in listbox

How can i get the previous selected value of the each selected list box with this.
You forgot to include the code that actually sets the value of the jQuery-data to the previous value!
Check out this solution: http://jsfiddle.net/uW2ND/2/
This fiddle illustrates the proper way to persist the previous value. More specifically, it stores each select box's previous value in its related data() container. The first time around it would not alert anything, since no previous value is set.
