Trimming information off address

dr00bie · #1 (**permalink**) 11-02-03, 01:49 AM

Hello all,

I'm really new to PHP (although I do have experience in ASP) and I am working on a Picture Gallery and I used the Basic Photo Album (BPA) script to do so, now I am trying to modify the script to my liking. I have the following problems: I need to find a way to trim some info off the address,

for example,

http://drewtestsite.wytheville.com/a....jpg&bg=FFFFFF

I need to get the Vintage (which is a dir.) out of the address...

here is my code as it stands

$includedir = trim($_GET["image"]);
$incdir = $_SESSION['incfolder'];
include "./albums/$incdir/vars.php";
echo "<html>";
echo "<title>$wr_title</TITLE>";
echo "<head></head>";

--The session code is there in an attempt to grab the folder info and session it for use later.

the problem is that $includedir is actually "Vintage/RRR=06.jpg&bg=FFFFFF" instead of just "Vintage"

I need it to just be what is in the address, any help would be appreciated.

Also, is there any way that I can include captions for each picture? The only way I can think of doing that is with a database. Does anyone have any other options?

Thanks,
Drew Laing

To see the error I am recieving, goto http://drewtestsite.wytheville.com/a...folder=Vintage
and click on a thumb.

Hi. Ok, use this line of code to extract the "Vintage" word from the image GET variable:

PHP Code:


			
$includedir = substr($_GET["image"], 0, 7); // Resolves to: $includedir = "Vintage"

If you will be getting different directories other than "Vintage" then give me a shout, ill make a regex for you.

Thank you very much, it worked like a charm!

Actually, I lied. It didn't work, it only works if the directory is 7 characters long, I didn't notice until I tried it with a different directory. Is there any way to use the same code:

$includedir = substr($_GET["image"], 0, 7); // Resolves to: $includedir = "Vintage"

but instead of the first 7 characters, it trims the variable until before the /.

view.php?image=Vintage/1.jpg&bg=FFFFFF

See the image=Vintage could be image=02032003 or something like that, but it will always have the / after the dir name, therefore if there is a way to take from 0 - the character before /

I dunno, it works out in my mind, but i don't know how to go about it...

Thanks,

Thats no problem. We can use the slash as a deliminator to split the string. Use this code:

PHP Code:


			
$get_dir = split("/", $_GET["image"]);

$includedir = $get_dir[0];

unset($get_dir[1]); // Discard the right hand side of the slash becuase it isnt needed.
