how to get the values of a radio button

[romano2717]

i have a set of radio buttons generated inside a loop then i append a variable from the loop to the name of the radio button and to the value. the question is, how do i get the value of the radio button being selected. here's a short code..

<?php
for($i=1; $i<=5; $i++){
echo "<input type = 'radio' name=q$i value = \'$i\'>";
}
?>

You can use foreach() to traverse through the radio buttons, then use isset() to see which was selected.

[php]
<?php
foreach($_POST['radio'] as $_val)
{
if(isset($_POST['radio']))
{
echo "Selected: $_val ";
}
}
?>
[/php]

How do you get the value of the radio group?

The VALUE attribute of the SELECTED radio option is carried over as part of the POST data:
e.g. when the form is submitted, $_POST['radioname'] would have a value equal to the VALUE of the radio option that was selected.
In order to work well, all the input elements must be given the same NAME; to identify each option uniquely, use an ID attribute.
To use your example:

<?php
    for($i=1; $i<=5; $i++){
        echo "<input type = 'radio' name='q' id='q$i' value = \'$i\'>";
    }
?>

After submitting the form, $_POST['q'] would have a possible value of 1-5, depending on the option selected.

Please, let me know if this helps.
