Filelist Widget (CMS)

Gestern gabs in ContentLion das Pagelist Widget und heute ist das FileList Widget dran 😉 Dabei handelt es sich um die Auflistung der Dateien im neuen Backend. Im Prinzip machen wir auch ähnliches. Wir kopieren die Grundfunktionen von /admin/includes/files.php in das neue Plugin filelistplugin.

Dessen /system/plugins/filelistplugin/info.php sieht so aus:

<?PHP
  $pluginInfo = new PluginInfo();
  $pluginInfo->path              = "filelistwidget";
  $pluginInfo->name              = "FileList Widget";
  $pluginInfo->description       = "Listet die Dateien im Dashboard auf";
  $pluginInfo->authorName        = "ContentLion";
  $pluginInfo->authorLink        = "http://contentlion.org";
  $pluginInfo->version           = "1.0.0";
  $this->Add($pluginInfo);
?>

Das Template /system/templates/files.html zieht nach /system/plugins/filelistwidget/templates/filelist.html um:

{IF:FILES_EXIST}
  <table>
    <tbody>
      {LOOP:FILES}
        <tr>
          <td>{VAR:IMAGE}</td>
          <td>{VAR:FILELINK}</td>
          <td>
            <a href="{VAR:DELETEURL}">
              <img src="{ICON:CROSS}" />
            </a>
          </td>
        </tr>
      {/LOOP:FILES}
    </tbody>
  </table>
{/IF:FILES_EXIST}
{IF:NOFILES}
  <p>{LANG:NO_FILES}</p>
{/IF:NOFILES}

Die Plugin-Klasse /system/plugins/filelistwidget/filelistwidget.php sieht so aus:

<?PHP
  class FileListWidget extends WidgetBase{
    public function load(){
      $this->headline = $GLOBALS['language']->getString("FILES");
      $uploadpath = getSetting("global","global","root")."content/uploads/";
      $template = new Template();
      $template->load("plugin_filelistwidget_filelist");
      $template->assign_var("UPLOADURL","/admin/index.php?page=upload");
      $template->assign_var("DIR",htmlentities($_GET['dir']));
      $template->assign_var("NEWFOLDERURL","/admin/index.php?page=files&dir=".urlencode($_GET['dir']));

      $dir = $_GET['dir'];
      if($_POST['newFolder']){
        FileServer::createFolder($uploadpath.$dir,$_POST['name']);
      }
      if($_GET['unlink']){
        unlink($uploadpath.$_GET['dir']."/".$_GET['unlink']);
        $template->assign_var("MESSAGE",$language->getString("FILE")." ".htmlentities($_GET['unlink'])." ".$language->getString("WAS_DELETED"));
      }
      if($_GET['rmdir']){
        rmdir($uploadpath.$_GET['rmdir']);
        $template->assign_var("MESSAGE",$language->getString("DIR")." ".htmlentities($_GET['rmdir'])." ".$language->getString("WAS_DELETED"));
      }
      $verzeichnis = openDir($uploadpath.$dir);
      $pre = "";
      foreach(split("/",$dir) as $cDir){
        $index = $template->add_loop_item("PATH");
        $path .= "/".$cDir;
        if($path == "/"){

          $template->assign_loop_var("PATH", $index, "LABEL",$cDir);
        }
      }
      $subFolders = FileServer::getFolders($uploadpath.$dir);
      if($subFolders){
        foreach($subFolders as $folder){
          $index = $template->add_loop_item("DIRS");
	      $template->assign_loop_var("DIRS",$index,"URL","/admin/index.php?page=files&dir=".$dir."/".$folder);
    	  $template->assign_loop_var("DIRS",$index,"LABEL",$folder);
    	}
      }
      if(trim($_GET['dir']) != "" & trim($_GET['dir']) != "/"){
        $template->assign_var("DELETEFOLDERLINK","<a href="/admin/index.php?page=files&rmdir=".$_GET['dir']."">Ordner löschen</a>");
      }
      else{
        $template->assign_var("DELETEFOLDERLINK","");
      }
      $files = FileServer::getFiles($uploadpath.$dir);
      if($files){
        $template->show_if("FILES_EXIST",true);
        $template->show_if("NOFILES",false);
        foreach($files as $file){
          $index = $template->add_loop_item("FILES");
          $path_info = pathinfo($uploadpath.$dir."/".$file);
          if(strtolower($path_info['extension'] == 'jpg') or
             strtolower($path_info['extension'] == 'jpeg') or
             strtolower($path_info['extension'] == 'gif') or
             strtolower($path_info['extension'] == 'png') or

             $template->assign_loop_var("FILES",$index,"IMAGE","<img src="/content/uploads/".$dir."/".$file."" style="max-width:100px;max-height:100px;" />");
          }
          else{
             $template->assign_loop_var("FILES",$index,"IMAGE","");
          }
          $template->assign_loop_var("FILES",$index,"FILELINK","<a href="../content/uploads".$dir."/".$file."">".$file."</a>");
          $template->assign_loop_var("FILES",$index,"DELETEURL","/admin/index.php?page=files&dir=".urlencode($_GET['dir'])."&unlink=".urlencode($file));
        }
      }
      else{

Die ist ähnlich wie die Datei aus dem „Admin-Bereich“. Fehlt nur noch die Änderung im /installer/installer.php:

      mysql_query("INSERT INTO `".$this->params[3]['praefix']."dashboards` VALUES ('admin/home', 3, 1, 'filelistwidget/filelistwidget.php');");
      mysql_query("INSERT INTO `".$this->params[3]['praefix']."widgets` VALUES ('lookaround/widget.php', 'LookAround', 'LookAround');");

      mysql_query("INSERT INTO `".$this->params[3]['praefix']."role_rights` VALUES (1,1);");
      mysql_query("INSERT INTO `".$this->params[3]['praefix']."role_rights` VALUES (1,2);");
      mysql_query("INSERT INTO `".$this->params[3]['praefix']."role_rights` VALUES (1,3);");
