Lift/Read PHP Varibles in HTTP Address Bar

n_wattam

okey, in php we all know you can pass data using the address bar as such;

index.php?name=neil&color=blue

What i need is the code/script which can read the http:// address bar in full, to detect if there is any varibles in it.

three is the fuction/command which can tell you the file name of the script, but i also want the data after the file name aswell.

Thanks in advance.

in this case:

$name = $GET['name'];
$color = $GET['color'];

as for script/path..

$_SERVER['SCRIPT_PATH'];

Hi,

This is my problem... if i know the varible names i can pull the value's, HOWEVER what if you dont know the varible names?

I want a script which can pull the full address something that will retreive the varible names and the values or

index.php?name=neil&color=blue

?name=neil&color=blue

$_SERVER['QUERY_STRING'];

will return everything after the '?'

Wow, cheers.. . PERFECT! 🙂

from there u can explode on '&' to get the string into an array of sections and then again on '=' to get the sections into an array of variables

might be a faster way... thats just the logic side of it 😉

Yeah, thats what i was thinking 🙂

The problem i was having i was running a script in my own CMS, both passing varibles in the address bar, however when i was using a forms from one script i was loosing the varibles of the other.

file.php?action=send

So as you can see the address bar was getting redefined, and loosing what other information i had there.

I could of just merged the script totally, but i wanted to keep them both serperate.

scrupul0us

well... u could just "build" the querystring up (which seems to be what u are doing)

thats how ive maintained state on sites before...

alternatively u could pass the variables into hidden fields on the next form and theyll get passed again

I thought of this, but what i wanted was to be able to insert this sciprt and make it easy to install into others, just by using the INCLUDE command.

This is where my next issue comes

Maybe something else you could help me with is.. I am using the

include('')

To read my other script into the CMS. However what i have found is, that sometime i loose paths.

Example.

Sub script (A) a contact form uses a folder called "_inc" where i might store images and sytlesheets etc.

However when you use the include command it actually becomes part of the main script, and any paths in that script are then nocked out of line.

scrupul0us

well yes... included files are treat as "inline"

e.g

/include/
/images/

anything in the include folder that pulls from images should be pathed like:

"images/"

however; if u were run a script in the include folder the images should be pathed as:

"../images/"

im sure theres a little snippet of code to handle this both ways, but i dont know it off the top of my head... maybe someone can chime in

n_wattam

Seemed to of solved that now aswell..

what i've done is placed a varible in my sub script call

$buffer_path

i've but this everywhere an external file is required in the script.

I can then set this varible with a fixed path in a config file, so no matter where script is called from, the paths are always ture.

Oh well i am happy... Thanks for all the help.

scrupul0us

no problem...

ive found using a hard path in included files works the best...

/var/www/... etc..
