How to use current page fields in selector?

Recommended Posts


Hi there! And thanks for Processwire!

I have an interesting task which i cannot fulfill as i want. Maybe someone could help me please?

Let's imagine a simple page structure of this kind:

Category 1
+ Item 1.1
+ Item 1.2
Category 2
+ Item 2.1
+ Item 2.2

My task is to attach some items to more than one category, at least to show some items on different frontend category pages. With PW, it's a piece of cake. I've just created a field called Items (of type Page Reference) and attrached it to Category template. Since i have lots of items inside each category i preferred to use Page Autocomplete input for my Items field. The pages available for autocomplete are restricted by a very simple selector:

template=item

It works like a charm. But later i decided to make this autocomplete even smarter and to exclude current category children items from it. I tried to update my selector this way...

template=item,parent!=(page)

...and oops, this broke my selector. My autocomplete founds nothing. Sorry, i had to replace the square braces by () because of this forum limitations, i swear i'm using square brackets in real-life selector!

What am i doing wrong? And is there any way to include current page info in autocomplete-related selectors? Thanks in advance!

Hmm, for some reason, I cannot see your post @theoretic! I am just seeing navigation buttons <next page> etc! I can see the post when I edit it (as a moderator - I didn't actually edit it). I am not sure whether it is my computer or my eyesight, or age! Anyone else seeing this? @Pete??

Sorry guys. It appears i've run into an issue with the forum editor. I tried to edit my post around 10 times, it's still not visible. So i'll try to post it as plain text.

Just make use of the $page variable like:

"template=item, parent!=$page"

Note the double quotes, or if you prefer:

'template=item, parent!='.$page

In the "Selector string" setting for "Selectable pages" you can use "page" to refer to the current page, but only if you also specify a subfield using dot syntax. In your case you would use page.id to exclude children of a parent:

template=item, parent!=page.id

Unfortunately I don't think this is documented anywhere.

      Hello! 
      I have a weird situation going on with my selector field, which I can't really get. 
      I create an array of titles as filter using this logic:
      firstname=Mike|Steve id=123|124|125 title*=Red|Blue|Green This is the field I am logging: 

      It goes in a for loop till it looks like what you see on the screen.
      So, my code regarding the selector string looks like this:
      $output = ""; foreach ($allorganisations as $item){ $output .= "$item | "; echo "<div style='color:red;'>//output String://</div>"; echo $output; } $selector_org .= ", title=$output"; I also log the output just after the matched pages are selected to be sure:
      $matches = $pages->find($selector_org); echo $output; foreach ($matches as $match) { echo " <li><a href='$match->url'>$match->title</a></li>"; } But you can see that it doesn't select all four needed pages, only selects one of them.
      Yet when I copy this exact selector text and manually put it in my selector, it works great... I even copy extra space and "|" and all that, it is supposed to be identical. I am very confused, what is the difference between the code? 
      foreach ($allorganisations as $item){ $output .= "Institute for Scientific Research in Cosmic Anthropoecology | Institute for Scientific Research in Cosmic Anthropoecology | Stanford Research Institute | Institute for Scientific Research in Cosmic Anthropoecology | Stanford Research Institute | Institute of Clinical and Experimental Medicine | Institute for Scientific Research in Cosmic Anthropoecology | Stanford Research Institute | Institute of Clinical and Experimental Medicine | Cosmists | "; echo "<div style='color:red;'>//output String://</div>"; echo $output; } $selector_org .= ", title=$output"; } ------>
      If you see where I'm going wrong, please enlighten me. I am very puzzled with this behaviour . :--)
      Best,

      Lister Selector
      A Process module that uses Lister/ListerPro, but with a selector string input instead of the normal InputfieldSelector filters.
      Features
      For power users, typing a selector string is often faster and more intuitive than fiddling with InputfieldSelector. It also lets you copy/paste selector strings that you might be using somewhere else in your code.
      Allows the Lister rows to be sorted by multiple fields (not possible in Lister/ListerPro)
      Allows the use of OR-groups (not possible in Lister/ListerPro)
      If ListerPro is installed you can run ListerPro actions on the listed pages - the available actions are defined in the module config.
      Bookmarks can be configured in the module config and accessed via the flyout menu for the module page. For your convenience you can copy/paste a bookmark string from the note at the bottom of the Lister Selector results.
      Usage
      Type your selector string on the Selector tab. The selector is applied when the "Selector string" field is blurred, so hit Tab when you have finished typing your selector.
      Unlike Lister/ListerPro, you can't sort results by clicking the column headings. Control the sort within the selector string instead.
      Superusers can jump to the module config (e.g. to create a bookmark) by clicking the cog icon at the top right of the module interface.
      The module is mostly intended for use by superusers, because in most cases site editors won't understand the ProcessWire selector string syntax. If you want another role to be able to access Lister Selector then give the role the "lister-selector" permission. Only superusers can define bookmarks because in ProcessWire module config screens are only accessible to superusers.

      Module config (when ListerPro is installed)

      Advanced
      If for any reason you want to create dynamic bookmark links to Lister Selector for a given selector you can do that like this:
      /** @var $pls ProcessListerSelector */ $pls = $modules->get('ProcessListerSelector'); // Define selector $selector = "template=foo, title%=bar"; // Define columns (optional) $columns = 'title,modified'; $pls_link = $pls->getProcessPage()->url . '?bm=' . $pls->urlSafeBase64Encode($selector . ':' . $columns); echo "<a href='$pls_link'>My link</a>";

      Hi,
      is there a hook after the current (active) page got created? Or which method got called in the Page class after the Constructor of the current page got initialized?
      Thanks.

      Hi guys,
      the field "redirect_last" of type DateTime got not updated. The update on the field "redirect_counter" works and got saved.
      Does anybody know what I did wrong in my code?
      if ($input->urlSegment(1) === 'redirect') { $page->of(false); $page->redirect_last = time(); $page->redirect_counter += 1; if ($page->save('redirect_counter')) { $session->redirect($page->website_url, 302); } } Thanks.

      Hey I'm building my first new site in well over a year and am a little rusty on selectors but particularly retrieving sub-fields of selected pages.
      I am trying to output the meta data of a blog post as follows.
      [Person Name] is just a field with a Page Reference and simple enough.
      [Job Title] is the sub-field within the page that was referenced above.
      I actually have it working with the following:
      Posted by: <?php if($page->insight_author) { echo $page->insight_author("<a href='{url}'>{title}</a>");} ?> , <?php $roles = $page->insight_author; foreach ($roles as $role) { echo "{$role->staff_role}";} ?> but was wondering how to do this with selector sub-selectors instead. My current code is probably quite 'old school'?
      Thanks
