codeigniter, using global variable

Question

i have a codeigniter application with 5 controllers one is the 'base' and the rest are inheriting form it, i am using global variable in the base to load in the view but it's not working i get (Undefined variable) when i load the view how can I fix this?

i'm using this function in the base to load the views


function _setContent($tplFile) {
            ob_start();
            $this->load->view($this->theme_dir . '/' . $tplFile, $this->tplData);
            $_content = ob_get_contents();
            ob_end_clean();

            $this->tplData['_content'] = $_content;
            $this->load->view($this->theme_dir . '/default', $this->tplData);
        }

$this->tplData // is the global variable

Not answering your question but you can set true as the third parameter to the view() function to return the content rather than echo-ing it (so you dont need to use ob_* functions) — Ben

Mamoum, what's the exact message you get? It's strange you get the Undefined error for $this->tplData, are you sure the error doesn't come from the view, where you call array indexes you didn't pass have? — Damien Pirsy

you can use config class.

$this->config->set_item('global_variable', $my_var);

now you can use this variable wherever you want

$this->config->item('global_variable');

try using define() instead of global to set your variable - http://php.net/manual/en/function.define.php

logically speaking, define is for constants and in OP's logic that ISN'T a constant. Although both available gloablly, globals and constats have different purposes, they're not interchangable

Well, what is the type of "tplData" ?

Damien Pirsy Over a year ago

Honestly, I don't find it clear, but since it's related to views I imagine it's something that changes from every method, so that one view loads something, another loads some other set of data and so on. If you define it as a constat, you need to redefine it everytime you want to pass the view different datas.

Ben Over a year ago

I agree with @DamienPirsy. Define doesn't seem like the right approach for this.

Damien Pirsy Over a year ago

Looking at the code, $this->tplData should hold all the variables passed to the view. The more I think about it, the more making it a constant gets wrong. And the more I don't see the need of making it a global variable too.
