I cant explain to you everything about sessions but I can give you an example, that will hopefully solve your problem.

 Help with Code Tags 
 PHP Syntax (Toggle Plain Text) 
// PAGE 1
session_start();
$_SESSION['abc'] = "2";
 
// PAGE 2
session_start();
echo $_SESSION['abc];
 
// PAGE 1
session_start();
$_SESSION['abc'] = "2";

// PAGE 2
session_start();
echo $_SESSION['abc];

Understand the logic behind it now?

Let me know how you go.

yes sir i understand the code but sir value '2' is dynamic not static..!!! value can be 2,3,4 etc whatever user can input in it..!!!!

in my example you clearly see, i take '2' as userinput not static input..!!!

//now page1
session_start();
$_SESSION['abc'] = ??? // how will you collect value of userinput
without sending it anywhere..!!

<input type='text' value="echo $_SESSION['abc'] " name="abc">



I hope now you get what exactly i want..!!!

is it possible to have Postback method on page Refresh.??
(Hold the values of a form on page refresh..!!)

You want to preserve the data or state of form input tag even after the page is posted back.

State management : home-made measures needed to preserve the state. Traditionally, statlessness hav been overcome with use of cookies, session, hidden fields, sticky form, and query string.

Here is an example code for everything to solves your questions:

 Help with Code Tags 
 php Syntax (Toggle Plain Text) 
// Page 1
session_start(); // Starts the session
<input type="textbox" name="textbox_name" /> // User enters 123
$_SESSION['textbox_session'] = $_POST['textbox_name'];
 
// Page 2
session_start(); // Starts the session
echo $_SESSION['textbox_session'];
// Page 1
session_start(); // Starts the session
<input type="textbox" name="textbox_name" /> // User enters 123
$_SESSION['textbox_session'] = $_POST['textbox_name'];

// Page 2
session_start(); // Starts the session
echo $_SESSION['textbox_session'];

You understand the logic? If not do some research?

The logic behind the code answers all his questions.
If he has further questions he just needs to ask.

Sorry sir but i dont understand that why you use $_POST when you not sending any data anywhere...
I hope you know that :
The built-in $_POST function is used to collect values from a form sent with method="post".

But we are here not sending data anywhere so it is useless to use $_POST..!!! thats what i m saying from very starting..!! I have to Hold data on page refresh(without using submit or without using any event)..!!!!
Sir this time you need to research little bit..!!!

Thanks for your Kind Patience..

How can you not be sending data?
The layout of your example, you would presumme it would be sending data.
If you not going to use 'post' use another 'session'.

List your code im getting tired of trying to guess what it is

Respected Sir i dont thnk my very first post was difficult to understand..!!! Now i try my best to made it more clear....!!!

 Help with Code Tags 
 PHP Syntax (Toggle Plain Text) 
<form action="add.php" method="post">
<table>
    <tr>
         <td>Items</td> 
         <td>Price</td>
  </tr>
   <tr>
     <? while($row=mysql_fetch_array($result)) { ?>
      {
      <td><?= $row['Item'];  ?> </td> //this will fetch Item from DB..
      <td><input type="text" name="price"></td> 
                                         // in this text box   user  input the price..!!
<?}?>
<button  type="button" onclick="return myPopup2();"><span>Add New Item</span></button></td> 
 
// This Add New Item Button will open a popup window through which I can add new Item... and on close of pop-up window the parent page will REFRESH... So that the NEW ITEM can be Displayed in the List..!!!
 
Note : Add Button is not a Submit button.. it jst call a Javascript Function to open a Window..!!
<form action="add.php" method="post">
<table>
    <tr>
         <td>Items</td> 
         <td>Price</td>
  </tr>
   <tr>
     <? while($row=mysql_fetch_array($result)) { ?>
      {
      <td><?= $row['Item'];  ?> </td> //this will fetch Item from DB..
      <td><input type="text" name="price"></td> 
                                         // in this text box   user  input the price..!!
<?}?>
<button  type="button" onclick="return myPopup2();"><span>Add New Item</span></button></td> 

// This Add New Item Button will open a popup window through which I can add new Item... and on close of pop-up window the parent page will REFRESH... So that the NEW ITEM can be Displayed in the List..!!!

Note : Add Button is not a Submit button.. it jst call a Javascript Function to open a Window..!!

Now i want to Hold the Value of Price TextBox which user input in it at time page refresh..!!

Suppose User got the page with 5 items...!!!

ITEMS | PRICE
ITEMS1 | 50 // Items are coming from db and User input the Price
ITEMS2 | 30
ITEMS3 | 20
ITEMS4 | 40
ITEMS5 | 60
ADD New ITEM (Button) // After Filling the Prices of First 5 Items,User Feels that He forgot to add ITEM 6 then he will Click on Add Item Button,a Popup Window Will Open through Which User Add Item 6 and on Close of that window... the Parent page will Refresh and Item 6 will displayed in the list..!!! But the values which User filled in Price textbox will be vanished...!!!

and I want to hold that Price Value on page refresh...!!!!

Now i hope clear Idea whta i want...??

I hope You reply with a Good Solution..!!

Thnk You Sir.!!!

Ok thats better now I understand your situation abit better.

But still you get the same answer, you have tried $_SESSION and $_POST ? Im sure either one would work if $_POST does not work cause technically there has been no information sent then sessions should work. popup2() is a function that opens a new php page I gather? So you should be able to declare either $_SESSION or $_POST within the value parameters of those text boxes.

In short have you tried $_POST or $_SESSION?
or you do not know how to implement either?
