Insert variable into define function

[Bman900]

define("DB_SERVER", "db854.pedrfora.net");

define("DB_USER", "dbo28387dd5085");

define("DB_PASS", "XjT.WtddW");

define("DB_NAME", "db28387dd5085");

 

I want to set it up so it would be like:

 

define("DB_SERVER", "$host");

define("DB_USER", "$username");

define("DB_PASS", "$password");

define("DB_NAME", "$name");

 

I have those variables defined in a config.php file. I already tried the above set up and it doesn't work for some reason. Am I doing something wrong?

What's going wrong?

 

And you don't need quotes round variables.

[Bman900]

Well here is my real code:

 

include ("../config.php");

define("DB_SERVER", $dbhost);

define("DB_USER", $dbusername);

define("DB_PASS", $dbpassword);

define("DB_NAME", $databasename);

 

and then here is the error

 

I get when I run it:

 

Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Isn't this your config.php?

 

define("DB_SERVER", $dbhost);
define("DB_USER", $dbusername);
define("DB_PASS", $dbpassword);
define("DB_NAME", $databasename);

 

Are you trying to include config.php in your config.php file?  ???

 

Personally I define like you did the first time.

 

<?php

define("DB_SERVER", "host");

define("DB_USER", "user");

define("DB_PASS", "pass");

define("DB_NAME", "dbname");

?>

This seems like a pretty odd way of doing things anyway.

 

If you've got variables already set, use them. If you want to use constants, just use constants instead. It sounds stupid to me to have both set to the same thing.

[Bman900]

I have a config.php file that will define all my databse info. I then used a log in system that has constants.php

 

I just simply want to use my variables defining my database info in my constants.php so people won't have to edit two file when they install the script.

[jackpf]

Well if you just used variables or constants, then you'd only have to edit one file as well.

 

But what's not working with your definitions?

[Bman900]

Well the values are passed on correctly as I echoed everything out. I then moved everything into the constant.php from the config.php so it was

 

$dbhost = "db854.perfora.net";
$dbusername = "dbo283875085";
$dbpassword = "XjT.WtgW";
$databasename = "db283875085";


define("DB_SERVER", $dbhost);
define("DB_USER", $dbusername);
define("DB_PASS", $dbpassword);
define("DB_NAME", $databasename);

 

which worked.

 

This is what that doesnt work:

include ("../config.php");
define("DB_SERVER", $dbhost);
define("DB_USER", $dbusername);
define("DB_PASS", $dbpassword);
define("DB_NAME", $databasename);

 

 

[jackpf]

And is the file that defines the constants including the file that sets the variables?

[Bman900]

Yea that would be the config.php you see up there.

[jackpf]

Hmm...try echoing out the variables in where you're defining them. Chances are you're script isn't inheriting them.

[Bman900]

It echoes out correctly but what I noticed is that if the config.php is in the same folder as constants.php it would work but when i tried it from my directory using ../config.php it didn't work but get this it still echoed out the variables correctly. I have never seen this before...

[Bman900]

Alright so I believe the problem was that include ("../config.php"); was looking for that file in my site directory while I had my file in another folder. This is what I had to do to make it work. include ("../draft/config.php");

 

So my config file was draft/config.php

While my constants was in draft/include/constants.php

 

("../config.php"); worked for all my other files that needed the database variable but those were inside draft/admin folder which is basically the same thing as draft/include

 

My question is what is the correct way of going back only one folder since ("../config.php"); takes it back to the directory....?

[jackpf]

../ is one directory up.

 

You should use require() if you're not sure your scripts are being included.
