I want to get the data from radio button when I submit it, but I don't know why I can't get the value from radio it.
My code
<?php
$choice = $_GET['choice'];
?>
<html>
<head>
</head>
<body>
<form action="index.php" method="POST">
<table align="center">
<tr><td>Please select</td></tr>
<tr><td><input type="radio" name="choice" value="0">aaaa</td></tr>
<tr><td><input type="radio" name="choice" value="1">bbbb</td></tr>
<tr><td><input type="radio" name="choice" value="2">cccc</td></tr>
<tr><td><input type="radio" name="choice" value="3">dddd</td></tr>
<tr><td><input type="submit" value="submit"></td></tr>
</table>
<?php echo"$choice";?>
</form>
</body>
</html>
Use $_POST Instead of $_GET to get data from form. Or you can use $_REQUEST also.Replace $_GET['choice'] with $_POST['choice'] or $_REQUEST['choice'].
You are using $_GET, but the form is posted. Use $choice = $_POST['choice'].
Your form is POST but you're looking for it in $_GET[]. Look for it in $_POST['choice'] instead.
The method of your form element should match the variable you access for the form data:
<form method="post">
// Need to use the $_POST[] array to access values
<form method="get">
// Use the $_GET[] array to access values
$_GET is typically used for url strings. Usually you will want the method of your form to be post.
If your form has attribute method set to POST, than you should use _POST global array like this - <?php $choice = $_POST['choice']; ?>
