products per page cookie problem

viveleroi0

I have a PHP script that has products on many pages... basically it is just paginated database results. I have an html select box with 5/10/20 as three different options, and when the user clicks on the "change" submit button, it changes the LIMIT portion of the sql query.

BUT... many customers had requested that they wanted to change that drop-down once... and have it stored in a cookie for their next visit. So, I have this to set the cookie:

setcookie("SiteNameProds[1]", "$limit", time()+2592000);

and this code is supposed to detect if that cookie was set, and if so... use that value. If not, use a default of 5.

if(isset($SiteNameProds[1]))
	{
	$limit=$SiteNameProds[1];
	echo"Prods Cookie IS Found";
	}
else
	{
	echo"Prods Cookie Not Found";
	if (empty($limit)) {$limit=5;}
	}

Yet what happens is that the first time you change the value using the select box form, the cookie is set, but you still see only 5 products on the page (the default), UNTIL you reload. The instant you visit the page with the cookie ALREADY existing, it sees the number and displays the correct products per page value.

Basically, the cookie is set when you change the number, yet the page display only changes after you reload ONCE after that...

any ideas?

Taken directly from php.net:

Cookies will not become visible until the next loading of a page that the cookie should be visible for. To test if a cookie was successfully set, check for the cookie on a next loading page before the cookie expires. Expire time is set via the expire parameter. A nice way to debug the existence of cookies is by simply calling print_r($_COOKIE);

I realized that through trial and error... but my issue is that SETTING the cookie seems to interfere with the variable $limit being set... it acts like the form info went to the cookie and the $limit variable appears to not be set...

Firstly if you want set cookie and then get the values it's almoast not work.

You can try use this sttyle:
1) php script get the values and set cookie.
2) use header("Location: script.php"); // reload page
3) when your page is reloaded you can user values what is saved into cookie

And I recommend use $_COOKIE["name"] instead of $name
