Radio Buttons to PHP-MySQL

Question

How can I get the value of a radio button like a "Gender Selector" (Male/Female) to PHP? I really need it for my register.php form. I tried googling it but they didnt provide how to get the value of it just how to generate it.

Code

<form action = "register.php" method = "post">
<input type="radio" name="sex" value="male">Male<br>
<input type="radio" name="sex" value="female">Female
</form>

PHP:

$sex = $_POST['radiobutton=sex'];

Answer 1

Your form needs a submit button. When you hit submit, on your register.php , you can do

$sex = $_POST['sex']

What you put in the brackets is what you specify in the name attribute for your radio buttons.

Seriously though... you should try to understand the basics of forms in general. Here's a decent tutorial

Answer 2

On the page with form:

<form action='register.php' method='POST'>
    <input type='radio' name='sex' value='male'/>Male
    <input type='radio' name='sex' value='female'/>Female
    <input type='submit' name='submit_sex' />
</form>

On register.php:

<?php

if (isset($_POST['submit_sex']))
    echo 'Gender is ' . $_POST['sex'];

?>
