Selectors - has_field

Recommended Posts

Hello,

I passed through a lot of documentation about selectors and a few post in the forum but and I did not find my answer so I'll try here :).

Question: Is there a way to find pages that have a certain field attached to his template ?

Use case:

// Site structure
Products
	Computers
		Computer #1 (has field cached_details)
		Computer #2 (has field cached_details)
	Electronics
		Test #1
	Pet Supplies
		Test #2 (has field cached_details but is empty)

// If I want to get all children of page "products" that contains the field "cached_details" I would do something like this

// $products => PageArray
$results = $products->children("has_field=cached_details");

// or this
$results = $products->children("cached_details!=null");

// Expected: $results would contains [Computer #1, Computer #2, Test #2]

// Instead I have to do this
$results = new PageArray();
foreach($products->children as $child) {
	if ($child->hasField("cached_details") === true) {
		$results->add($child);
	}
}

 

Thank you in advance guys :),

      I want to add a dependent SELECT field on my template page that lists pages from a parent "sub-page" in the current parent node.
      On /product1/page I have the field "photo" which is a SELECT field.
      I want the SELECT to list pages from /ROOTPARENT/photos.
      The idea is that I can reuse the same photo in many places - but only need to keep it update it once under /product1/photos.
      My page structure looks like so:
      /product1/page /product1/photos/photo3 (template=photos) /product2/photos/photo9 I have tried adding these Selector Strings on the Field (Setup -> Fields -> PHOTO -> Input tab -> Selectable Pages field group -> Selector String):
      parent=/product1/page, template=photos, sort=name WORKS (but only on children of current product). parent=page.rootParent ... parent=$page.rootParent ... parent=$page.rootParent parent=$parent ... parent=$parent1 When using a SELECT Input Field Type, the editing pages gives the fatal error "Unrecognized operator: $". parent=parent ... parent=. Returns an empty list How might I find child pages from the current "/product1/photos/ page"?
      Your inputs are appreciated. Thanks.

      Hello,
      I've just upgraded to 3.0.165 (and updated my Ubuntu version as well) and on my localhost, I am facing a weird issue : all my requests having the ~= selector cause a Mysql error with this message :

      PDOException #HY000 SQLSTATE[HY000]: General error: 3685 Illegal argument to a regular expression. I have no idea what is going on. If I change my request from

      $visualizer = $pages->get("name~=visualizer"); // Triggers the error
      to
      $visualizer = $pages->get("name=visualizer");
      or
      $visualizer = $pages->get("name~*=visualizer");
      My code works fine again.
      Any idea ? Shall I change all my requests (but from what I understand by reading the documentation, ~= exists and fits my needs : all words in any order [though I do understand that in my example above it may be useless since I have only one word])
      Thanks !

      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.
      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.
      Screenshots
      Process page

      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'); $selector = "template=foo, title%=bar"; $pls_link = $pls->getProcessPage()->url . '?bm=' . $pls->urlSafeBase64Encode($selector); echo "<a href='$pls_link'>My link</a>";

      Hello all,
      using PW 3.0.148 with the regular site profile for a blog, I got an an empty pagination output when I had a Toggle field in the selector.
      The Toggle Fieldtype was introduced with https://processwire.com/blog/posts/pw-3.0.139/ .
      The selector resulting in empty pagination:
      $posts = $pages->find("parent=blog, sort=-date, limit=10, toggle_field=0"); It worked well, when I replaced the Toggle field with a Checkbox field:
      $posts = $pages->find("parent=blog, sort=-date, limit=10, checkbox_field=0"); So the prerequisites for the pagination to work are given.
      The settings for the Toggle field were:
      Formatted value: Integer Label Type: Yes/No Input Type: Toggle buttons Default selected option: No Thanks for any hints!

      Hi there,
      I have a problem constructing a selector that finds all pages that refer to pages with a specific template.
      I have pages using an event template and I want to show events based on a specific context. In this example I want to filter the results and only show event pages that relate to a specific template (exhibitions) in their page field related_pages.
      What I tried:
      $events = $pages->find("template=event, related_pages.template.name=exhibition"); Unfortunately it does not work (0 results).
      Same with this:
      $events = $pages->find("template=event, related_pages=[template.name=exhibition]"); At the moment I am helping myself with the following lines, but I have a strong feeling that there is a more efficient solution:
      $events = $pages->find("template=event"); foreach($events as $event){ if(!count($event->related_pages->find("template=exhibition"))){ $events->remove($event); } }  
      I really hope that one of you can help me out.
      Thanks in advance!
      Flo
