Session array and diplaying images on other file

Peuplarchie · April 20, 2009

Good day to you all,

Session are always fun, this time I pushing 2 array to a session, one a list of folder and the other a list of files :

<?php

session_start(); 

?>




function ahah(url, target) {
  document.getElementById(target).innerHTML = ' Retreiving and loading image... <br/> Recherche et chargement de l\'image...';
  if (window.XMLHttpRequest) {
    req = new XMLHttpRequest();
  } else if (window.ActiveXObject) {
    req = new ActiveXObject("Microsoft.XMLHTTP");
  }
  if (req != undefined) {
    req.onreadystatechange = function() {ahahDone(url, target);};
    req.open("GET", url, true);
    req.send("");
  }
}  

function ahahDone(url, target) {
  if (req.readyState == 4) { // only if req is "loaded"
    if (req.status == 200) { // only if "OK"
      document.getElementById(target).innerHTML = req.responseText;
    } else {
      document.getElementById(target).innerHTML=" AHAH Error:\n"+ req.status + "\n" +req.statusText;
    }
  }
}

function load(name, div) {
ahah(name,div);
return false;
}



//  End -->
</script>

<?php

$directory = "Art/";
function dirList ($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) {

    $folder_modified[] = "<span style=\"color:#003366;\"><img src=\minus_icon.gif\"  id=\"plusminusimg".preg_replace('/\//','_',$directory."".$file)."\"  onclick=\"Toggle('".preg_replace('/\//','_',$directory."".$file)."'); return false;\" /><a href=\"#\" onclick=\"load('folder_view.php?dir=".$directory."&file=".$file."','boxdisp');return false;\"><b>".$file."</b></a>";

        // Else not styled
        }else{
        array_push($files,$file);
     $filenamecor = substr($file, 0, -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>';}


    }
    }

    echo "<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) {

      echo "<li id=\"pic\"><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
      echo "</li>\n"; //close this list item after all files and folders in $folder have been looped through
   
   
    }

    foreach($files as $key=>$file) {

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


    echo "</ul>\n"; //close the unordered list
}
   $_SESSION['folders']=$folders;  
   $_SESSION['files']=$files;  

dirList($directory);

When you click on a folder it bring

you to a page like that :




<?PHP
session_start(); 
$file = $_GET['file'];
$dir = $_GET['dir'];

?>



<html>
<head>

    <SCRIPT language="JavaScript">
    <!--
    if (document.images)
    {
      preload_image = new Image(25,25); 
      preload_image.src="http://test.peuplies.info/PHP/Photos_gallery/<?PHP echo $dir."".$file; ?>"; 
    }
    //-->
    </SCRIPT>
  


</head>
<body>


<?PHP

$dir = $_GET['dir'];
$file = $_GET['file'];
echo "<center><img src=\"".$dir."".$file."\" width=\"400px\"/></center>"; 


?>





</body>
</html>

How can I list the image in that folder reading from the session array the folder passed thru the url ?

Thanks !
