process the pass by get url...

[penny336]

dear all,

i am coding a search form.
it contains several textbox..
user can enter some criteria to search mysql db..
it can be "alex ho" <--- contains space ..
my result form can split into several pages based on the number of result pages..

say if >30 rows.. has next page url..

here is the partial next page url, cos need to pass the criteria every time without use session
$footer .= "search.php?gname=$gname"

the problem is , if the criteria contains space , the $footer will truncate..
it becomes
$footer .="search.php?gname=alex"

instead of
$footer .="search.php?gname=alex ho"

actually i solve the problem by using str_replace(" ","%20",$gname);
but i am not sure any other special character will crash my code.

may i know if there any exsiting "class" or function can process the passed url.. so that any unpredicated problems can be fixed.

thx
alex

Instead of using str_replace, use [man]urlencode[/man] to massage $gname into a suitable format. The data will then survive the trip through your querystring unscathed.

Instead of just replacing spaces, you should really be using a function like [man]urlencode/man to encode the arguments in the query string (especially if they are dynamic). i.e.

$footer .= "search.php?gname=" . urlencode("alex ho"); 

Of course, the above example is pointless since you could just manually encode the static string and then remove the unnecessary function call. If the string "alex ho" was a dynamic variable, then it would be worth parsing using the urlencode function.
