radio button

Nickosssss

Hello there

i ve a sql select that returns some field and i present them in table

for each field returned i also put a radio button as well

how do i pass the value of a field when the user selects the radio button?
<td><input type = radio name = radio value = "<? $HTTP_POST_VARS[ $id] ?>"></td>????

thank you

using the code you posted, on your form processing page you will have a variable called $_POST['radio'] containing the selected id (if any one was selected at all).

so do i need to put the $_POST into the value of the radio?

$query = "SELECT topic.top_id, top_name, staf_lname, topic.top_diff FROM topic, staff, top_staff WHERE staff.staff_id = top_staff.staff_id and topic.top_id = top_staff.top_id ORDER BY top_name ";

$db = new mysqli('localhost','root','323232');
 $db -> select_db('project');

$result = $db->query($query);

if ($result)
{
while($r = mysqli_fetch_assoc($result))
{
$id = $r['top_id'];
$top = $r['top_name'];
$staff = $r['staf_lname'];
$diff = $r['top_diff'];

	?>
	<form action = test2.php method = post>
	<table>
	<tr>
	<td><? echo $id; ?> </td>
	<td><? echo $top; ?> </td>
	<td><? echo $staff; ?> </td>
	<td><? echo $diff; ?> </td>
	<td><input type = radio name = radio value = "<? $id; ?>"></td>


	<?
}

}
?>

</tr>
<tr>
<input type = submit name = sub value = s></tr>

</table>
</form>
<?

no, but you need to [man]echo[/man] the $id variable into the value attribute of the radio tag (which you are not doing in your code as posted).

well i ve tried that but still does not pass through the second php file

consider this very simple example:

<?php
if (!isset($_POST['submit']))
{
	echo '
	<form action="" method="POST">
	choose a number:<br>
	<input type="radio" name="number" value="1"> 1<br>
	<input type="radio" name="number" value="2"> 2<br>
	<input type="radio" name="number" value="3"> 3<br>
	<input type="radio" name="number" value="4"> 4<br>
	<input type="radio" name="number" value="5"> 5<br>
	<input type="submit" name="submit" value="submit">
	</form>
	';
}
else
{
	if (isset($_POST['number']))
	{
		echo 'you chose ' . $_POST['number'];
	}
	else
	{
		echo 'you did not choose anything';
	}
}
?>
