Re: [PHP-DB] Too many $_GETs?

The limit on GETs is not something to do with PHP or MySQL, it's a web
server standard. I forgot what the length limit is for a URL (256, 1024
?), which is what a GET is. If you want to keep variables or
information from page to page you should use sessions. You can manage
sessions without using cookies.

The browser may also have something to do with it.....
Use hidden input forms to transfer data from page to page. Uses POST and 
makes for a prettier URL.
<input type="hidden" name="a" value="<?php echo $a; ?>">
<input type="hidden" name="b" value="<?php echo $b; ?>"> <input 
type="hidden" name="c" value="<?php echo $c; ?>">
<input type="hidden" name="foo" value="<?php echo $foo; ?>">
<input type="hidden" name="bar" value="<?php echo $bar; ?>">
put those in the form, and change the method to POST. Then you can access 
the data via the $_POST var.
<?php
echo $_POST['a'];
echo $_POST['b']; echo $_POST['c']; echo $_POST['foo']; echo $_POST['bar'];
?>
And yes, it is that simple.
