How to keep entered value until user click confirm button

[ghjk]

I have a web page which is used to enter user data. In there I have 4 buttons named as "Submit, Confirm,Edit,Cancel". User should enter data and click "Submit " button. Then I want to display all information he entered and when user click confirm button only it should submit to the DB. Could you please tell me what is the best way? Do I need to use java script? How can I keep the form data after user click on submit button?

<form name="Adduser.php" id="Adduser.php" action="<? echo $PHP_SELF?>">
 
<input name="Confirm" value="Confirm" id="Confirm" src="../images/Confirm.jpg" type="image"  alt="add" height="30"  width="73"  style="visibility:hidden"/>
                    <input name="Edit" value="Edit" id="Edit" src="../images/Edit.jpg" type="image"  alt="add" height="30"  width="73" style="visibility:hidden" />
                    <input name="Submit"  id="Submit" src="../images/Submit.jpg" type="image"  alt="add" height="30"  width="73" value="commit" />
 
                    <input 
                    id="Cancel" src="../images/Cancel.jpg" type="image"  alt="cancel" height="30"  width="73" />
</form>

one way to do it would be posting all values back to the input fields so that you can submit the values again (without further doing), doing an extra "preview" and at the same time inserting the confirm button.

// generic code
<input name="test" value="$_POST['test']" ... >
...
if (isset($_POST['submit'])) 
{
    // echo posted vars in a neat way
    echo <input name="confirm" ... >
}

Notes:
- your <form> ID is invalid
- $_SERVER['PHP_SELF']

I'm sorry. I can't get it.

ok then

step 1
(HTML) write your form as usual (this you should have already done)

step 2
(PHP) write some code to display the submitted values for the user to confirm (no DB action)
this is to be triggered if the submit button is pressed

step 3
take the code of step 1 and insert the posted values as default values*

<input type="text" name="test"> // step 1
<input type="text" name="test" value="<?php echo postback('test'); ?>">
// value is the input's default value
// postback($index) has to return $_POST[$index] if the submit button was pressed

step 4
insert the confirm button if the submit button is pressed

step 5
(PHP) do the DB action if the confirm button is pressed


* there are endless possibilities to do so only limited by your imagination and capabilities
