Hi, i've ran into an issue with a template and wanted to get some help. I've done some printf's to try debugging the root cause and hitting a loss. If anyone has any additional suggestions on what I can try, please let me know. Any help is greatly appreciated!

 

current code from Abstract.php on line 271:

    public function renderObject($obj, $parent = NULL)
    {
error_log("Render: " . print_r($render, TRUE), 3, "/var/tmp/my-errors.log");
error_log("Obj: ".  print_r($obj, TRUE), 3, "/var/tmp/my-errors.log");
error_log("Parent: ".  print_r($parent, TRUE), 3, "/var/tmp/my-errors.log");
        $render = $this->getRender("object");
        if( $render != NULL )
        {
            return $render->proccess($obj, $parent);
        }

        return "";
    }

Output from error_log is posted here:

As the error message says, $render

$render = $this->getRender("object");

is a string. Not an object. Are you misunderstanding how getRender() works?

[apryan]

yes, i don't know how either function work. getRender I believe is trying to pull the render id i believe though. Could you explain what the functions are suppose to be doing? i appreciate it.

    public function proccess($obj, $parent = NULL)
    {
        $this->_parent = $parent;
        $html = "";
        if( is_array($obj) ) 
        {
            $obj = (object) $obj;
        }

        if( method_exists($obj, "xxxinit") ) 
        {
            $obj->xxxinit();
        }

        $method_name = "_" . $obj->type;
        if( method_exists($this, $method_name) ) 
        {
            $html .= $this->$method_name($obj);
        }
        else
        {
            $html .= $this->_default($obj);
        }

        return $html;
    }

    public function getRender($name, $auto = true)
    {
        if( !preg_match("/^[a-z\\_]+\$/i", $name) ) 
        {
            return NULL;
        }

        if( !isset(self::$_renders[$name]) ) 
        {
            if( $auto ) 
            {
                $name = ucfirst($name);
            }

            $filename = str_replace("_", "/", $name) . ".php";
            if( !file_exists(dirname(__FILE__) . "/" . $filename) ) 
            {
                return NULL;
            }

            $class = "Moto_Html_Render_" . $name;
            if( class_exists($class) ) 
            {
                self::$_renders[$name] = new $class($this->_engine);
            }
            else
            {
                self::$_renders[$name];
            }

        }

        return self::$_renders[$name];
    }

That code will return an object (or null). There's something else going on.

It seems $render isn't showing any data anyway as it is blank when the error occurs. I did move the function to within !=NULL and it still shows the error log but doesn't contain any data. Any idea what I could check? The error does occur on first page load. I was able to bypass the page load on some occasions however once in, no object is loaded on the pages. Just the background images.

I have no idea what your code is so no, I don't really have any ideas for what to look for. Assuming you have a copy installed locally, try running with a debugger.

For what it's worth, the error_log() code is executed before $render is defined. See the following snippet:

error_log("Render: " . print_r($render, TRUE), 3, "/var/tmp/my-errors.log");
error_log("Obj: ".  print_r($obj, TRUE), 3, "/var/tmp/my-errors.log");
error_log("Parent: ".  print_r($parent, TRUE), 3, "/var/tmp/my-errors.log");
$render = $this->getRender("object");
