I’m trying to use the global $IN method to grab a url query value, but it’s saying GBL is undefined:

Example url:
http://donq.mine.nu/test/_chainselect/?_value=5

- I do include global $DB, $IN; at the top of the script
- I do have PHP enabled, and tried both on input and output
- I’ve tried numerous different query keys and values

$IN->GBL(‘_value’) results in:

Undefined property: Input::$GBL in /Users/pete/Projects/Clients/2009-07 - Don Q/src/system/core/core.functions.php(637) : eval()'d code on line 8

print_r($IN) results in:

            [3] => ACT
        )

)

No where does GBL even show up, any clue?

Have you seen the docs on the Input class? Superglobals are explained in somewhat more detail there.

Of course I read that doc. It doesn’t address my issue at all.

I get how the superglobals are supposed to work, but I don’t understand why they’re not working. Every other example on the docs page works except for $ID->GBL(). That’s what I’m asking for help with figuring out. Shouldn’t a var dump of $IN contain a GBL array if it was working? And if the input class was working, wouldn’t a check for $IN->GBL(‘_value’) return false if it couldn’t find it (according to the docs), but it’s showing GBL as undefined. Everything but GBL works for me. Why is that and where should look to figure it out?

Or, I suppose GBL wouldn’t show up in the var dump, since it’s a class function, but I still don’t get why calling it as a function returns nothing.

Even just print_r($_GET) returns only this:

Array ( [/test/_chainselect/] => )

I don’t get it. FYI, I checked another non-EE site on my same dev server, GET variables do get passed by print_r($_GET), so I’m lost in some EE-specific problem.

Can you show us what your URL rewrite looks like?  That may be the culprit here.  If you take it out of the equation, can you get _value to dump?

It must be in the .htaccess. I whittled down my .htaccess to the 3 lines that are required to recreate it:

RewriteEngine On
# <a href="http://expressionengine.com/wiki/Remove_index.php_From_URLs/#Include_List_Method">http://expressionengine.com/wiki/Remove_index.php_From_URLs/#Include_List_Method</a>
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ /index.php?/$1 [L]

Also, if I go to:

/index.php/test/_chainselect/?id=&name=field_id_8&_value=5

And do:

global $IN;
echo $IN->GBL('_value');

...I get “5”.

If I remove index.php/ and use that .htaccess code, I get to the right page, I don’t see 5.
If I use that .htaccess code AND go to the url with index.php/, I do see 5.

I’m obviously not a mod rewrite master, or I’d have thought to check .htaccess at the start. Any ideas?

Do you have to force query strings on this server?

-greg

No, I tried $_GET on another site on the same install of MAMP Pro, and tried turning Force Query Strings on and off for this one; same deal.

Here is the phpinfo():
http://lunabar.mine.nu/

Unless you’ve done some configuring, I don’t believe you need query strings when you run on MAMP.  That being said, for the time being go ahead & remove the .htaccess from the mix and put index.php back in your control panel and give it another try.

-greg

Yeah, like I said, it works that way (index.php included in the url, with htaccess or not). I’m using the htaccess method from the EE wiki, any idea why this is happening?

If I go to:

/index.php/test/_chainselect/?id=&name=field_id_8&_value=5

global $IN;
echo $IN->GBL('_value');

...It works, I get “5”.

If I remove index.php/ and use that .htaccess code, I get to the right page, I don’t see 5.
If I use that .htaccess code AND go to the url with index.php/, I do see 5.

 

Peter,

In your htaccess, change

RewriteRule ^(.*)$ /index.php?/$1 [L]

to this by removing the ?

RewriteRule ^(.*)$ /index.php/$1 [L]

Wow John, thanks, that did it. Thanks so much.
I need to bone up on my mod rewrite.

Seems strange that Leevi Graham would include the question mark in his .htaccess generator:
http://leevigraham.com/cms-customisation/expressionengine/lg-htaccess-generator/

Anyways, thanks for the help.

Peter,

Glad to help. Leevi just includes a broad range of stuff for the htaccess. A lot isn’t necessary and it is a base to customise yourself. Feel free to start a new thread if you have any more questions.

P.S. I have to come clean. I ran into the same problem the other day and it took me a very long time to figure out 😊
