How to send value attribute from radio button in PHP

Question

I am struggling with sending the value of a radiobutton to an email.

I have coded 2 radiobuttons, where I have set the first on to be default checked.

The form and values work, however the radio button value is not submitted.

Any wise words?

Without your code, all we can do is copy and paste from the HTML spec. — Dan Blows, Feb 07 '13 at 09:49

When you select a radio button and click on a submit button, you need to handle the submission of any selected values in your php code using $_POST[] For example: if your radio button is:

<input type="radio" name="rdb" value="male"/>

then in your php code you need to use:

$rdb_value = $_POST['rdb'];

Check whether you have put name="your_radio" where you have inserted radio tag

if you have done this then check your php code. Use isset()

e.g.

   if(isset($_POST['submit']))
   {
    /*other variables*/
    $radio_value = $_POST["your_radio"];
   }

If you have done this as well then we need to look through your codes

The radio buttons are sent on form submit when they are checked only...

Radio buttons have another attribute - checked or unchecked. You need to set which button was selected by the user, so you have to write PHP code inside the HTML with these values - checked or unchecked. Here's one way to do it:

The PHP code:

<?PHP
    $male_status = 'unchecked';
    $female_status = 'unchecked';

    if (isset($_POST['Submit1'])) {
         $selected_radio = $_POST['gender'];

         if ($selected_radio == 'male') {
                $male_status = 'checked';
          }else if ($selected_radio == 'female') {
                $female_status = 'checked';
          }
    }
?>

The HTML FORM code:

<FORM name ="form1" method ="post" action ="radioButton.php">
   <Input type = 'Radio' Name ='gender' value= 'male'
   <?PHP print $male_status; ?>
   >Male
   <Input type = 'Radio' Name ='gender' value= 'female' 
   <?PHP print $female_status; ?>
   >Female
   <P>
   <Input type = "Submit" Name = "Submit1" VALUE = "Select a Radio Button">
</FORM>

There shouldn't be a space in `= =`. – Barmar Feb 07 '13 at 09:48 — Barmar, Feb 07 '13 at 09:48

Should be :

HTML :

<form method="post" action="">
    <input id="name" name="name" type="text" size="40"/>
    <input type="radio" name="radio" value="test"/>Test
    <input type="submit" name="submit" value="submit"/>
</form>

PHP Code :

if(isset($_POST['submit']))
{

    echo $radio_value = $_POST["radio"];
}
