    It's seems like the "sending to the other page code never get executed ?

    I always have this function proble can somebody so me my mistake !


    Here is my code :

    PHP Code:



    <?php

    error_reporting
    (E_ALL);
    ini_set("display_errors""on");

             
    set_time_limit(0);
            
    $directory "Art/";


    function 
    dirList ($directory)
    {
     
        
    //create 2 arrays - one for folders and one for files
       
    $folders = array();
       
    $files = array();
     
        
    // create a handler for the directory
        
    $handler opendir($directory);
     
        
    // keep going until all files in directory have been read
    while (false !== ($file readdir($handler))) {  
     
            
    // if $file isn't this directory or its parent,
            // add it to the results array
            
    if ($file != '.' && $file != '..')
           
            
    // If file is directory, mark it in bold.

           
    if(is_dir($directory.$file)) {
            
    array_push($folders,$file);
            
                if (
    time() - filemtime($directory.$file) < 604800) {
        
    $folder_modified[] = "<span style=\"color:#DB1212;\"><li><div class=\"folder\"><img src=\"plus_icon.gif\"  onclick=\"Toggle('".preg_replace('/\//','_',$directory."".$file)."'); return false;\" /><b>".$file."</b></div>";
    } elseif (
    time() - filemtime($directory.$file) < 31556926) {
        
    $folder_modified[] = "<span style=\"color:#003366;\"><li><div class=\"folder\"><img src=\"plus_icon.gif\"  onclick=\"Toggle('".preg_replace('/\//','_',$directory."".$file)."'); return false;\" /><b>".$file."</b></div>";
    } else {
    $folder_modified[] = "<span style=\"color:#000000;\"><li><div class=\"folder\"><img src=\"plus_icon.gif\"  onclick=\"Toggle('".preg_replace('/\//','_',$directory."".$file)."'); return false;\" /><b>".$file."</b></div>";}
     
            
           
            
    // Else not styled
            
    }else{
            
    array_push($files,$file);
         
    $filenamecor substr($file0, -4);
        if (
    time() - filemtime($directory.$file) < 604800) {
        
    $file_modified[] = '<span style="color:#DB1212;">'.$filenamecor.'<span>';
    } elseif (
    time() - filemtime($directory.$file) < 31556926) {
        
    $file_modified[] = '<span style="color:#003366;">'.$filenamecor.'<span>';
    } else {
    $file_modified[] = '<span style="color:#000000;">'.$filenamecor.'<span>';}
     
     
        }
        }

    $output "";

        
    $output .= "<ul id=\"".preg_replace('/\//','_',substr($directory,0,strlen($directory)-1))."\">\n"//start a new unordered list for every iteration through dirList
     
    $dircor $directory;
        
    // tidy up: close the handler
        
    closedir($handler);
        foreach(
    $folders as $folder=>$file) {
            
          
    $output .= "<li><div class=\"folder\">".$folder_modified[$folder]."</div>"//echo the folder name enclosed in a list item
            
    dirList($directory.$file.'/'); //loop through the contents of $folder
          
    $output .= "</li>\n"//close this list item after all files and folders in $folder have been looped through
       
       
        
    }
     
        foreach(
    $files as $key=>$file) {

          
    $output .= "<li><a href=\"index.html\" onclick=\"load('image_view.php?dir=".$dircor."&file=".$file."','boxdisp');return false;\">&nbsp;".$file_modified[$key]."</a></li>\n"//echo the file name enclosed in a list item
        
    }
     
     
        
    $output .= "</ul>\n"//close the unordered list

          
    return $output;

    $filename 'menu.html';
    // Let's make sure the file exists and is writable first.
    if (is_writable($filename)) {

        
    // In our example we're opening $filename in append mode.
        // The file pointer is at the bottom of the file hence
        // that's where $somecontent will go when we fwrite() it.
        
    if (!$handle fopen($filename'a')) {
             echo 
    "Cannot open file ($filename)";
             exit;
        }

        
    // Write $somecontent to our opened file.
        
    if (fwrite($handle,$output) === FALSE) {
            echo 
    "Cannot write to file ($filename)";
            exit;
        }

        echo 
    "Success, wrote () to file (".$filename.")";

        
    fclose($handle);

    } else {
        echo 
    "The file ".$filename." is not writable";
    }

    }
        

    dirList ($directory);
        




    ?>
    the result of this is a blank page.


    Thanks !

    And you get no error messages? Do you see anything in view-source?

    I'm wondering about this
    PHP Code:
                // if $file isn't this directory or its parent,
                // add it to the results array
                
    if ($file != '.' && $file != '..')
                
    // If file is directory, mark it in bold.
                   
    if(is_dir($directory.$file))
            { 
    It looks like there's a missing curly brace.

    And here
    PHP Code:
        $output .= "</ul>\n"//close the unordered list
        
    return $output;
        
    $filename 'menu.html'
    Won't the return exit the function without running any more of the code?
