Retrieving the Value of a Radio Button using PHP

Code for RadioButton:

<h1 style="margin:0; margin-top:10px; padding:0; padding-left:25px; padding-bottom:10px; font-family:sans-serif;">
</h1>
<div style="background:#1794FF; color:#fafafa; padding:10px;">
<h3></h3>
<table>
<tr>
<td>
<input type="radio" name="radiog_lite" id="radio1" class="css-checkbox" />
<label for="radio1" class="css-label">Neighbourhood Only</label>
</td>
<td>
<input type="radio" name="radiog_lite" id="radio2" class="css-checkbox" checked="checked"/><label for="radio2" class="css-label">Zipcode Only</label>
</td>
<td>
<input type="radio" name="radiog_lite" id="radio3" class="css-checkbox" />
<label for="radio3" class="css-label">Near Zipcode</label>
</td>
<td>
<input type="radio" name="radiog_lite" id="radio4" class="css-checkbox" />
<label for="radio1" class="css-label">City-Wide</label>
</td>
</tr>
</table>
</div>
<div style="background:#1794FF; color:#222; padding:10px;">

Php Code: 

 <?PHP

 $selected_radio = $_POST['radiog_lite'];
  print $selected_radio;

   ?>

After a form submission I arrive at the code above. However, it says the value is "on". Why isn't it printing the chosen radio button name?

Use form method "post" and also put value for each radio:

<form method="post">
<table>
<tr>
<td>
<input type="radio" name="radiog_lite" id="radio1" class="css-checkbox" value="Neighbourhood Only" />
<label for="radio1" class="css-label">Neighbourhood Only</label>
</td>
<tr>
</table>
<input type="submit" />
</form>

May you can assign a value:

PHP Code

 <form method="POST">
    <input type="radio" name="radiog_lite" id="radio1" class="css-checkbox" value="1" />
    <label for="radio1" class="css-label">Neighbourhood Only</label><br>
    <input type="radio" name="radiog_lite" id="radio2" class="css-checkbox" checked="checked" value="2"/>
    <label for="radio2" class="css-label">Zipcode Only</label><br>
    <input type="radio" name="radiog_lite" id="radio3" class="css-checkbox" value="3" />
    <label for="radio3" class="css-label">Near Zipcode</label><br>
    <input type="radio" name="radiog_lite" id="radio4" class="css-checkbox" value="4" />
    <label for="radio1" class="css-label">City-Wide</label><br>
    <input type="submit" value="Submit">
 </form>

PHP Code:

 <?php
  $selected_radio = $_POST['radiog_lite'];
  print $selected_radio;
 ?>

Use a value attribute on your input radio.

A radio button is has a default value of "on", you should specify your value in your input initialization like so: 

<input type="radio" name="radiog_lite" id="radio2" class="css-checkbox" value="Your Value Here" checked="checked"/><label for="radio2" class="css-label">Zipcode Only</label>

So you can replace "Your Value Here" with "Zipcode Only" for this one. The label is just to describe the radio button value for the front-end user.
