scopes within a view - El Forum - 09-04-2008 [eluser]ggoforth[/eluser] Hello All, just a quick question about the scope of functions within a view. I was having an issue accessing a config item in the main config file, when calling from a function within a view. So my code below does not work: ------ VIEW FILE ----- Code: <?php However, the code below does work: ------ VIEW FILE ----- Code: <?php So, when I call the config item from outside the function in the view, everything works fine. I will say I solved the problem using the second method, I'm just curious about why I can't call the $this->config->item() function from within a function in a view. Thanks all!

If you do Code: function echoConfigItem(){ As a side note it's better not to add functions to your view files. They should be display only. scopes within a view - El Forum - 09-04-2008 [eluser]ggoforth[/eluser] [quote author="xwero" date="1220531280"] As a side note it's better not to add functions to your view files.

Yeah, I agree with you about not having them in the views, but this is a legacy project, and I'm just fixing a few things, but not doing a rewrite of the program. Thanks again!

Code: function echoConfigItem() |
