Hi,
Does anyone know where I can find a tutorial on the bits of code in the address bar after .php ?
E.g. the one I can see now is /posting.php?mode=newtopic&f=1
I can't search for one as I don't know what it's called.

Thanks,
Tom

http://de2.php.net/manual/en/language.v ... ternal.php should help for basics

Those bits in the adressbar are gathered via $_GET[]
e.g.

url: domain.com/index.php?name=george
Goal: echo out what is transported in "name"

Code: Select all

$valueOfName=$_GET["name"];

echo $valueOfName;
//same as

echo $_GET["name"];

quick lesson:

anything after the question mark "?" will be considered variable information by any scripting language. to separate multiple variables the ampersand sign "&" is used.

so say for example I have the following URL:

Code: Select all

http://www.mysite.com/mypage.php?var1=bob&var2=larry
on the page mypage.php, I can do something with those variable names and their corresponding values.

in the case below I'll just echo them out for display:

Code: Select all

echo (isset($_GET['var1']) ? $_GET['var1'] : "Var 1 is not set");
echo (isset($_GET['var2']) ? $_GET['var2'] : "Var 2 is not set");
obviously you can do whatever you want with variables, but as a baseline, that should get you going...
