I want to have a modifier which results a value from an array.
This is what I got now, and I don't see anything wrong.
What's wrong?
Code:

function smarty_modifier_get_config_value($string, $section, $confvar = 'conf')
{
GLOBAL ${confvar};

    return ${confvar}[$section][$string];
}

The file containing this modifier is called "modifier.get_config_value.php", and it remains inside the 'plugin' dir I specified with Smarty. So that couldn't be the problem.
But I won't get any result from it Sad

I get an output when I insert
Code:
echo "lala";
in the modifier, but I can't get anything from the array Sad

I include my config file into the Php file which calls the template using this modifier, the config file containing the array looks like this:

Code:
<?php
$conf['bgcolor']['esta']   = "#00CC00";
$conf['bgcolor']['scout']   = "#FFB76F";
$conf['bgcolor']['explo']   = "#FF0000";
$conf['bgcolor']['home']   = "#99CC99";
$conf['text_bgcolor']['esta']   = "#00CC00";
$conf['text_bgcolor']['scout']   = "#FFB76F";
$conf['text_bgcolor']['explo']   = "#FF8989";
$conf['text_bgcolor']['home']   = "#99CC99";
?>

Any idea what I'm doing wrong, or how I could get this working?

Thanks

Try $$confvar instead of ${confvar}.

By the way, you might want to consider alternative approaches of storing your required data. Perhaps create a single known global var to store an array of data items.

ie. GLOBAL $mystorage

$$confvar doesn't do much Sad

What do you mean with the alternative approaches of storing required data?
Don't I have one global var containing the array of data items? ($conf, but to make it dynamic I want to be able to give also a different $confvar)

Could you explain some more?

Thanks

I meant that if you did something like this:

Code:
function smarty_modifier_get_config_value($string, $section, $confvar = 'conf')
{
GLOBAL $confvars;

    return $confvars[$confvar][$section][$string];
}

The thing is, is that you don't want to "pollute" your global namespace with too many vars.

You can also extend smarty and store the array there:
Code:
class MySmarty extends Smarty
{
var $confvars;
}

$smarty = new MySmarty;


Your modifier would then be something like:
Code:
function smarty_modifier_get_config_value($string, $section, $confvar = 'conf')
{
    return $this->confvars[$confvar][$section][$string];
}


I hope that is clearer.

Still, I'm not sure why you are going through these hassles for conf values which are usable directly from within templates via ##. Surprised

I need the flexibility to change the values of the config files from a webpage, and with the pear::Configuration class it's easy.
I don't know if the pear::Configuration class' inifile-type has the same layout as the Smarty Config file layout?

And most important, I need to get the value of the config file dynamicly.
The result of a query from the DB has a field which contains the name of a section (it's a site for a scouting group, and the group is splitted in differents groups selected by the age of the members), and I want every group to have a different layout color. So I want to use the groupname to get the right color from a config file.
( I hope I made clear 'why' I want this Smile)
