I made this simple radio group below but I’m having some difficulty calling it in PHP.

<form id="form1" name="form1" method="get" action="pre_process.php">
    <p>
      <input name="q" type="text" size="80"/>
    </p>
    <p>
      <input type="submit" id="search_button" />
    </p>
    <p>
      <label>
        <input type="radio" name="SearchFormat" value="0" id="SearchFormat_0" />
        Agreggated</label>
      <br />
      <label>
        <input type="radio" name="SearchFormat" value="1" id="SearchFormat_1" />
        Non-Aggregated</label>

I’m using the following code but I get an error of undefined index: SearchFormat

if($_GET["SearchFormat"]==0)
{
    do stuff...

Can somebody tell me what I’m doing wrong?

Thanks

    Just see at your browser, May be there is possibility that you are running your code by direct from folder . But you have to run your page with localhost address.
    Look at the code below.
    This is First PHP file: radio.php

        <html>
   <body>
   <form action="test1.php" method="get">
  <label>
 <input type="radio" name="SearchFormat" value="0"  />
Agreggated</label>  <br />

 <label>
<input type="radio" name="SearchFormat" value="1"  />
Non-Aggregated</label>
<input type="Submit" name="btn" value="SearchFormat" />

    Now another PHP file is:test1.php

     <?php   
 if($_GET['SearchFormat']==0)
   {
   echo "I ma checked";
   }
else  
   {
   echo "I am not checked";
   }
 ?>

    You have to run this PHP file by writing localhost/radio.php at the browser.
    Second php file than automatically runs as you click on SearchFormat button.

    And also one thing you have to save your all php page in WAMP/XAMP folder.
