hi,

I'm trying to get a template class of mine to work correctly, but during the part of the code that should be outputting the parsed data, I get this error:

Warning: Invalid argument supplied for foreach() on line 60

now I'm using a foreach as the template will be working with loops and I'm trying to make it all work on one template file(meaning using one tremplate for a loop action not separating it into 3) as currently my template file count is at 160 and I wish to cut that down a bit for ease

now here is the template class I'm using:

PHP Code:

class templateEngine implements templateCore{



    #declare data members

    private $output;

    private $tags = array();

    private $templateFile;

    

    #function that will open template file.

    public function __construct($file){

        #see if template file exists.

        if (!file_exists($file)){

            throw new Exception('Template file ('.$file.') was not found.');

        }else{

            #get the contents of the template file

            $contents = file_get_contents($file);

            

            #see if template file is empty.

            if(empty($contents)){

                throw new Exception('Template file is empty.');

            }else{

                #Add template contents into output variable.

                $this->output = $contents;                

            }             

        }        

    }

    

    #function that will parse template tags.

    public function parseTags($tags){

    

        if(count($tags)<1){

            throw new Exception('No tags were found to be parsed.');

        }

        

        foreach($tags as $tag=>$data){

            #if data is array, traverse recursive array of tags

            if(is_array($data)){

                $this->output = preg_replace("/\{$tag/",'',$this->output);

            }

                      

            $this->output = str_replace('{'.$tag.'}', $data, $this->output);

        }    

    }

    

    #function that will output the final set.

    public function outputHtml(){

     

    $html = '';

        foreach($this->output as $val){

            $html .= $val;

        }

        return $html;

    

    }    

} 

I have tried several things and so far I haven't gotten far. I hope something here knows why this doesn't work. If you need any thing else, please let me know.

much thanks in advanced
