Hello Processwire Community Lets say I have a Multi-User-System where I can create/update as "normal" user new events, dates, multimediapages, imagepages etc.... As Admin I can create organisers(owners) and assign them respectively to specific users. Module for creating/updating pages: Fredi - Friendly Frontend Editor Scenario: Add new Imagepage under Multimedia > Images Important Fields select_organiser(FieldtypePage)(btw. this field is assigned to the user template) PHP-Selector for "select_organiser" if(wire('user')->isSuperuser()){ return $pages->find("template=organiser"); } else{ return $pages->find("template=organiser, id=".wire('user')->select_organiser); } Templates image-index(is assigned to Image-Page) -> Fields: only title - > images-index.php Only show the image pages which has the same organiser like the current user. <?php $out .="<h3>$title verwalten</h3> <div class='span11'> <div class='btn-pos-1 add'>" .$fredi->setText("<i class='fa fa-plus'></i> Bild erfassen")->hideTabs("children|delete|settings")->addPage("image", "title|select_organiser", $pages->get(1153)). "</div> <table id='example' class='row-border' cellspacing='0' width='100%'> <thead> <tr> <th>ID</th> <th>Bildname</th> <th>Bild</th> <th>Beschreibung</th> <th>Veranstalter</th> <th>aktualisiert</th> <th></th> <th></th> </tr> </thead> <tbody>"; if($user->isSuperuser()){ $images = $pages->find("template=image"); } else{ $images = $pages->find("template=image, select_organiser=$user->select_organiser"); } foreach ($images as $i_item) { if($i_item->image){ $thumb = $i_item->image->size(50, 50); } $out .= "<tr> <td>{$i_item->id}</td> <td>{$i_item->title}</td> <td><a class='large_img' href='{$i_item->image->url}' ><img src='{$thumb->url}' /></a></td> <td>{$i_item->image_body}</td> <td>{$i_item->select_organiser->title}</td> <td>".date('Y-m-d', $i_item->modified)."</td> <td><a href='{$i_item->url}'><i class='fa fa-eye'></i></td> <td>".$fredi->setText("<i class='fa fa-pencil'></i>")->renderAll($i_item)."</td> </tr>"; } $out .= " </tbody> </table> </div>"; images(is assinged to children-items of Image-Page) -> Fields: title, image, image_body, select_organiser -> images.php At the beginnnig of the template it checks if the select_organiser of the current user is the same as the select_organiser of the current image page. <?php if($user->select_organiser == $page->select_organiser || $user->isSuperuser()){ $out .= "<h3>{$page->parent->title} Details</h3> <div class='span8'> <table class='detail-view table table-striped table-condensed'>"; $out .= "<tr class='odd'><th>ID</th><td>{$page->id}</td></tr>"; //get all fields: $all_fields = $page->fields; foreach($all_fields as $field){ if($field->type == "FieldtypeImage"){ $out .= "<tr class='odd'><th>{$field->label}</th><td>{$page->get($field->name)->url}</td></tr>"; } else if($field->type == "FieldtypePage"){ $out .= "<tr class='odd'><th>{$field->label}</th><td>{$page->get($field->name)->title}</td></tr>"; } else{ $out .= "<tr class='odd'><th>{$field->label}</th><td>{$page->get($field->name)}</td></tr>"; } } $out .= "<tr class='odd'><th>erstellt</th><td>".date("Y-m-d H:i:s", $page->created)."</td></tr> <tr class='even'><th>aktualisiert</th><td>".date("Y-m-d H:i:s", $page->modified)."</td></tr> </table> </div> <div class='span3'> <div id='sidebar'> <ul class='well nav nav-list' id='yw1'> <li class='nav-header nav-header'>Aktionen</li> <li><a href='{$page->parent->url}'><i class='fa fa-list'></i> Bilder auflisten</a></li> <li>".$fredi->setText("<i class='fa fa-pencil'></i> Bild bearbeiten")->renderAll($page)."</li> </ul> <br /> </div> </div>"; } else{ $session->redirect($error404->url); } The Problem of this System is that the user still can access to image-pages in the backend that dont have the same organiser. Its only view protected. So finally my Question: Can i specifiy a PHP-Selector for the editable pages for the Page Edit Per User Module. Like: return $pages->find("template=images, id=".wire('user')->select_organiser); So that the user can edit the image - pages which has the same organiser like him?

I am looking for some advice on setting up a multi-user and multi-school website/application. Each school and user will be created by a superuser; so there is no "self registration" functionality (at this point). On the back-end, It is important that when user1 logs in he can only see and edit the school1 players. On the font-end each school will have it's own url e.g. site.com/school1 Any hints would be much appreciated. Users user1 - school1 user2 - school1 user3 - school2 Pages schools school1 school2 players football players player1 - school1 player2 - school1 player3 - school2 cheerleaders cheerleader1 - school1 cheerleader2 - school2 advertisments advert1 - school1 advert2 - school2
