Hi
I am just stucked. Would be great if someone can help me.
I have created form. Has also created a session in php to view the data and reuse it for editting any data. While trying to edit all the default values which are inputed in the form are coming in all fields except the value for radio button(no value is checked)
I am giving a short coding for all 3 pages:
Page 1: (HTML- FORM)
<html>
<body>
<form action="page2.php" method="post">
Name : <input type="text" name="name"/>
Discount: <input type="radio" name="discount" value="2"> TWO </br>
<input type="radio" name="discount" value="4"> THREE
<input type="submit" value="Submit"/>
</form>
</body>
</html>
PAGE 2 (Displaying Input Values)
<html>
<?php session_start();?>
<body>
<form action="page3.php" method="post">
Name :<?php
$name=$_POST['name'];
$_SESSION['name']=$name;
echo $_SESSION['name']; ?>
Discount:<?php
$discount=$_POST['discount'];
$_SESSION['discount']=$discount;
echo $_SESSION['discount']; ?>
<input type="Submit" value="Edit">
</form>
</body>
</html>
Page 3 (editing field with prefilled fields) The problem is in this section:
<html>
<?php session_start();?>
<head>
<?php
$name=$_SESSION['name'];
$discount=$_SESSION['discount'];
echo
"<form action=\"page4.php\" method=\"POST\">
Name :<input type=\"text\" name=\"name\" value=\"$name\"/> </br>
<input type=\"radio\" name=\"discount\" value=\"2\"<?php if($discount=='2') echo 'checked=\"checked\"'; ?> TWO
<br/>
<input type=\"radio\" name=\"discount\" value=\"4\" <?php if($discount=='4') echo 'checked=\"checked\"'; ?> FOUR
<br/>
<input type=\"submit\" value=\"Confirmed\"/>";
?>
</body>
</html>
When I am clicking Edit button on page2, page3 is appearing where name field is prefilled but no radio buttons are checked. I need help for the radio button to be checked according to the information given on first page.
Also, it will be a great help if someone can tell me how to validate the fields on page3 before processing to page4.
THank you ver very much.......

Re: Recalling Session Value for Radio Buttons
The code you posted is invalid for many reasons that I care not to enumerate.
Your problem may be related to the fact that these inputs are not submitted by the browser and will, therefore, not have an index in $_POST:

Your problem may be related to the fact that these inputs are not submitted by the browser and will, therefore, not have an index in $_POST:
- Unchecked radio buttons
- Unchecked checkboxes
- Inputs without names
- Buttons that were not clicked
