Children of a page as a role even when not logged in

Recommended Posts

I am not sure whether this has been asked before. I tried googling, but got slightly different topics, so I post this as a new topic now. Sorry.

I have a «protected» page. The guest user is not allowed to view this page, only a few roles. Now the customer want this page to appear in the navigation even for guest users. When they click on the item they should be presented with the Processwire login then they should be able to view the protected page. This works if I give them the direct link, and if they are logged in, the protected page also appears in the navigation.

This is the code for the navigation. It's a two-level navigation. Sorry about the alternative syntax. I know it's controversial, but I like it for templating.

  <? foreach (top_pages() as $top): ?>
    <li id="nav_<?=$top->id?>" class="top">
      <a href="<?=$top->url?>"><?=$top->title?></a>
      <? if ($top->numChildren): ?>
        <ul>
          <? foreach ($top->children as $child): ?>
            <li class="sub"><a href="<?=$child->url?>"><?=$child->title?></a></li>
          <? endforeach ?>
        </ul>
      <? endif ?>
    </li>
  <? endforeach ?>

Now, how can I get the children of $top as a given role even when not logged in?

      Hello PW Community, really glad that discovered this CMS recently, it is very strange it took so long That idea of no front design limitations is just awesome!
      Need to say that I have a bit of knowledge of html and css, but almost no php, so I need your help.
      What I want to do is an article posting  cms, with this structure:
       
      - Homepage - Projects - Articles -- Category 1 --- Articles of category 1 -- Category 2 --- Articles of category 2 - About - Contact Found this ProcessWire Profile https://github.com/tutsplus/how-to-create-an-ajax-driven-theme-for-processwire
      It covers almost all my needs, except the menu. When I add a childpage for this page http://artist.nicegrp.com/publications/world-world/ , World:World doesn't appear under Writings & Publications.
      I need a menu that works like a breadcrumb, that shows on the menu the category that you are viewing. So when I'm in articles page, on the menu it shows only articles and it's categories. When I get into a category, that category takes state active link but doesn't show on the menu links and titles for contained articles. How can I do that?
      Sorry for my long writing and English, it is not my native but I hope you understood what I need. Can you help me with that?
      Thank you

      Hi all,
      I use version 3.0.62. Is there a way to delete all children of a page with one click - without parent page?
      thanks

      SYNOPSIS
      A little guide to generating an sitemap.xml using (I believe) a script Ryan originally wrote with the addition of being able to optionally exclude child pages from being output in the sitemap.xml file.
      I was looking back on a small project today where I was using a php script to generate an xml file, I believe the original was written by Ryan. Anyway, I needed a quick fix for the script to allow me to optionally exclude children of pages from being included in the sitemap.xml output.
      OVERVIEW
      A good example of this is a site where if you visit /minutes/ a page displays a list of board meetings which includes a title,  date, description and link to download the .pdf file.
      I have a template called minutes and a template called minutes-document. The first page, minutes, when loaded via /minutes/ simply grabs all of its child pages and outputs the name, description and actual path of an uploaded .pdf file for a visitor to download.
      In my back-end I have the template MINUTES and MINUTES-DOCUMENT. Thus:


      So, basically, their employee can login, hover over minutes, click new, then create a new (child) record and name it the date of the meeting e.g. June 3rd, 2016 :

       
      ---------------------------
      OPTIONALLY EXCLUDING CHILDREN - SETUP
      Outputting the sitemap.xml and optionally excluding children that belong to a template.
      The setup of the original script is as follows:
      1. Save the file to the templates folder as sitemap.xml.php
      2. Create a template called sitemap-xml and use the sitemap.xml.php file.
      3. Create a page called sitemap.xml using the sitemap-xml template
       
      Now, with that done you will need to make only a couple of slight modifications that will allow the script to exclude children of a template from output to the sitemap.xml
      1. Create a new checkbox field and name it:   sitemap_exclude_children
      2. Add the field to a template that you want to control whether the children are included/excluded from the sitemap. In my example I added it to my "minutes" template.
      3. Next, go to a page that uses a template with the field you added above. In my case, "MINUTES"
      4. Enable the checkbox to exclude children, leave it unchecked to include children.
      For example, in my MINUTES page I enabled the checkbox and now when /sitemap.xml is loaded the children for the MINUTES do not appear in the file.

       
      A SIMPLE CONDITIONAL TO CHECK THE "sitemap_exclude_children" VALUE
      This was a pretty easy modification to an existing script, adding only one line. I just figure there may be others out there using this script with the same needs.
      I simply inserted the if condition as the first line in the function:
      function renderSitemapChildren(Page $page) { if($page->sitemap_exclude_children) return ""; ... ... ...  
      THE FULL SCRIPT WITH MODIFICATION
      <?php /** * ProcessWire Template to power a sitemap.xml * * 1. Copy this file to /site/templates/sitemap-xml.php * 2. Add the new template from the admin. * Under the "URLs" section, set it to NOT use trailing slashes. * 3. Create a new page at the root level, use your sitemap-xml template * and name the page "sitemap.xml". * * Note: hidden pages (and their children) are excluded from the sitemap. * If you have hidden pages that you want to be included, you can do so * by specifying the ID or path to them in an array sent to the * renderSiteMapXML() method at the bottom of this file. For instance: * * echo renderSiteMapXML(array('/hidden/page/', '/another/hidden/page/')); * * patch to prevent pages from including children in the sitemap when a field is checked / johnwarrenllc.com * 1. create a checkbox field named sitemap_exclude_children * 2. add the field to the parent template(s) you plan to use * 3. when a new page is create with this template, checking the field will prevent its children from being included in the sitemap.xml output */ function renderSitemapPage(Page $page) { return "\n<url>" . "\n\t<loc>" . $page->httpUrl . "</loc>" . "\n\t<lastmod>" . date("Y-m-d", $page->modified) . "</lastmod>" . "\n</url>"; } function renderSitemapChildren(Page $page) { if($page->sitemap_exclude_children) return ""; /* Aded to exclude CHILDREN if field is checked */ $out = ''; $newParents = new PageArray(); $children = $page->children; foreach($children as $child) { $out .= renderSitemapPage($child); if($child->numChildren) $newParents->add($child); else wire('pages')->uncache($child); } foreach($newParents as $newParent) { $out .= renderSitemapChildren($newParent); wire('pages')->uncache($newParent); } return $out; } function renderSitemapXML(array $paths = array()) { $out = '<?xml version="1.0" encoding="UTF-8"?>' . "\n" . '<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">'; array_unshift($paths, '/'); // prepend homepage foreach($paths as $path) { $page = wire('pages')->get($path); if(!$page->id) continue; $out .= renderSitemapPage($page); if($page->numChildren) { $out .= renderSitemapChildren($page); } } $out .= "\n</urlset>"; return $out; } header("Content-Type: text/xml"); echo renderSitemapXML(); // Example: echo renderSitemapXML(array('/hidden/page/'));  
      In conclusion, I have used a couple different processwire sitemap generating modules. But for my needs, the above script is fast and easy to setup/modify.
      - Thanks

      How do I change the permissions for Who can access this page for a single page.

      This page inherits the admin template.

      I'm currently creating a new page called Settings using admin template and assigning it to a process of a module. I can see the Settings tab in superuser, but I can't see them in a role I defined called 'client'.

      So, how can i control what the client sees for admin template? Is there a page specific overwrites for permissions. I've tried allowing access in admin template view, edit. But still doesn't work

      Alright. So I'm converting a site I already have to Processwire (really enjoying it so far!). I wanted to convert the previous tables that I had data in to Processwire pages. But I'm wondering what the optimal way to structure pages would be.
       
      So basically, I have three main tables.
      Users (and all accompanying information)
      Items (and all accompanying information)
      Aquariums (each user only has 1 aquarium. Currently, user_id is a FK)
      Fish (type of item. Aquariums may have multiple fish)
      Aqua_settings (Things like lightness, temperature, etc)
       
      So in my current setup, there are a lot of Foreign Keys. I could accomplish essentially the same thing by using the Page Reference field.
      Alternatively, I could make fish and aqua_settings both be children of Aquarium. I could differentiate by doing $aquarium->children('template=aqua_settings'); or something.
       
      So my question is...should I be using the Page Reference field or structuring the pages as children? (Or are both equally fine depending on how I want to go about doing things)
