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
