[RESOLVED] get url

lwq

anyone has any idea, as in, how do i get the full url(including whatever comes after the ? and #,which means whatever that is typed into the address bar)?

i have tried to user the $_SERVER variable but is not able to get the full url.
i need to get the stuff that comes after the "#"

Using strictly PHP (or any other server-side language), I don't believe you can retrieve data after a # in the URL. Why? Because this is a special character - it means that the browser should load the contents of the page (with the URI being everything before the pound sign) and then scroll to the tag with the name of whatever is after the #.

As such, the browser doesn't actually send that information to the server - it just sends the URI data before the # to the server. If you wanted to get the full URL including the # data at the end, you might be able to do this with some client-side code, such as Javascript.

hmm...thanks! seems like javascript can do the job... how do i go about doing it?
i need the stuff after the '#' as a variable to run some other javascript.

Try using window.location to retrieve what was entered in the address bar (including the # data).

You'd probably just use the Javascript split() function to split the string on the # symbol, and use the 2nd array item (index 1) to get what was entered after the # symbol.

EDIT: Here's an example I managed to type up:

<script type="text/javascript">
var pound_tag = window.location.toString().split('#')[1];

if(!pound_tag) {
	alert('No data after # !');
} else {
	alert('Data after #: ' + pound_tag);
}
</script>

what do you mean regarding the split() function? i don't quite understand as I am not good in javascript.

See my example I added onto the end of my last post.

thanks, it works!by the way, i have another question:does it mean that when i want to check if the 'pound_tag = something', do i use a similar method like in php?as in:

if(pound_tag = something){ runthisfunction(var1,var2,var3,...); }

bradgrafelman

Well, something is probably a string, so you might want to enclose it in quotes. Also, a single equal sign is not a comparison operator (in neither PHP nor Javascript), so you'd need to correct that as well.

Other than that, yeah, that should work.

ok... thanks so much.... 🙂
