[monkeypaw201]

i'm not sure im doing this right...

 

<?php 
function sitename()
{
echo $row_Settings['airline_name'];
}

 

then to display it

 

<?php sitename(); ?>

 

its not working though..

Where are you getting $row_Settings?  If it's from another part in the script, do:

<?php
function sitename()
{
global $row_Settings;
echo $row_Settings['airline_name'];
}
?>

Brilliant, but what does the global part do??  ??? ???

<?php
function sitename()
{
global $row_Settings;
echo $row_Settings['airline_name'];
}
?>

 

or if it's coming from another page you'd have to do something like

 

<?php
function sitename()
{
$row_Settings= $_REQUEST['row_Settings'];
echo $row_Settings['airline_name'];
}
?>

There's something called variable scope.

 

You can't use outside variables inside a function unless you reference them as global.

@Yankee: NEVER use $_REQUEST.  Just use $_GET, $_POST, or $_COOKIE.  $_REQUEST is SO insecure.  Don't use it.  Please.

Wow

 

so one could create functions to hold repetive data, stick all of them in one file, and then include that file, then all you have to do is just type

 

<?php sitename(); ?> wherever you need that particular function?

 

sorry to change the subject.. just had to comment.. L:P

Probably wouldn't want to do that though.  Depends on the situation.

sorry to re-open, but i just went and it seems really weird...

 

i have that same code, but to make it display i have to put

<?php echo sitename(); ?>

even after i already echoed in the function, it works in some cases, but not others, any suggestions?

 

EDIT::

 

i figured it would help if i put the code is causing problems with;

 

href ="<?php 
fullurl() . "Themes" . $row_Settings['theme_directory']; 
?>Style/style.css" />

when the function is

<?php 
function fullurl() 
{ 
global $row_Settings;
echo $row_Settings['base_url'] . $row_Settings['directory'];
}
?>

 

the problem is that it actually prints that on the page while the page is loading...

OK, thanks DarkWater... had no Idea, guess I should redo all my scripts then...
