<input type="radio" name="nav" value="a1" /> A 1
<input type="radio" name="nav" value="a2" /> A 2
<input type="radio" name="nav" value="b1" /> B 1
<input type="radio" name="nav" value="b2" /> B 2

<input type="radio" name="nav" value="c2" /> C 2

navigate.php

<?
if ($_POST['nav']==a2) {
    echo "<meta http-equiv=\"refresh\" content=\"0;URL=page_1.php\">";} ?>

<iframe src="1.html"/>

When i select a2 and press go it goes to page_1.php but inside the frame. I want the main window to go to page_1.php. Is there any solution for this??

You can use the target attribute of the form tag to determine the frame/window the submit should be targetting to. In you case use target=”_top” to open the result in the top frame (the main window)

<form id="abc" method="post" target="_top" action="navigate.php">
<input type="radio" name="nav" value="a1" /> A 1
<input type="radio" name="nav" value="a2" /> A 2
<input type="radio" name="nav" value="b1" /> B 1
<input type="radio" name="nav" value="b2" /> B 2
<input type="radio" name="nav" value="c1" /> C 1
<input type="radio" name="nav" value="c2" /> C 2
<input type="submit" name="submit" value="Go" />
</form>

The problem is that it will open in the top frame (the window) in all cases, so independent of what you choose as a value for the radio button.
