Post to self?

[Jon Pike]

if test.php is this file:


<?php
$lang = $_POST["lang"];
print $lang;
?>



<form method=post action=test.php >
<input type=image src=engFlag.jpg name="lang" value=en>
<input type=image src=fraFlag.jpg name="lang" value=fr>
</form>



Why won't it print $lang; after having one of the images clicked?

Does here on Firefox.

But on Internet Explorer it only posts "lang_x" and "lang_y" for the
coordinates of the click.

http://www.w3.org/TR/html4/interact/forms.html#h-17.4.1

The "." from the standard is transformed by PHP into "_".

IE's behaviour here is very unhelpful, and probably a violation of the
standard; it says the x and y are included in the submitted data, but doesn't
say to eliminate the original name/value pair.
