Plugin: return array

Hi forecepts.dev,

I’ve moved this down to Development and Programming. Can you share with us your actual code and what you are trying to accomplish? We can’t help without a lot more info.

Thanks!

Hi

Currently I return values as string format. I wish to return as Array format, I store my value in session as Array format. But when i return as $arr, it gave me error message.

Please kindly advise, thanks.

function getarray() { $arrString=”“; $arr = array(); // check if correct parameters were passed if (!$this->EE->TMPL->fetch_param(‘name’)) { show_error(‘Session Plugin: name parameters must be entered’); } $name = $this->EE->TMPL->fetch_param(‘name’);

    // if no active session we start a new one
    if (session_id() == "") 
    {
        session_start(); 
    }

    if (isset($_SESSION[$name]))
    {
        $arr= $_SESSION[$name];
    }


    for ($a=0;$a<=count($arr)-1;$a++)
    {
        for ($b=0;$b<=count($arr[$a])-1;$b++)
        {
            $arrString .=$arr[$a][$b];

            if ($b==count($arr[$a])-1)
            {
                $arrString .=";";
            }
            else
            {
                $arrString .=",";
            }

        }

    }
    //$arrString = implode(',', $arr);
    return $arrString;

}

How is my code?? is it any mistake??

You cannout return an array value from a plugin. The template parser expects a string or an instance of a class that has the magic method __toString implemented (which ultimately just returns a string).

What are you trying to achieve in the template with your plugin?
