Get child pages but put child 4 first

Recommended Posts

<?php 
$Cats=$pages->find("parent=1086, id!=$page, sort=sort"); 
foreach($Cats as $Cat) {
echo "

I have a selector that pulls in 4 child pages of a parent and the order is set to reflect the order of the tree.

My client has asked that instead of

Cat 1 | Cat 2 | Cat 3 | Cat 4

we instead display

Cat 4 | Cat 1 | Cat 2 | Cat 3 

However, I can't change the sort order in the tree.

Can anyone guide me on the correct approach here?

Thanks

The item you want to give special treatment to is the last item in the WireArray, so you could use pop() to get that item and remove it from the WireArray:

Alternatively here is a more flexible approach that you can use for any item in the WireArray:

Thanks Robin. These are new to me but I get the general mechanics. 

What is the console part of your screenshots ? A module?

I believe that ProcessWire automatically sorts out duplicates so you could do

$Cats = $pages->find("parent=1086, id!=$page, sort=sort");
$Cats->prepend( $Cats->eq(4) );

foreach($Cats as $Cat) {
}

@Peter Knight why do you cannot sort the pages manually, or let the client sort them manually?

I can't sort them manually because the order is used in other layout components across the site.

Technically I could build an extra kind of sortable page list but I also want to keep this really simple for a client who will be maintaining the site.

Hi Tom

Thanks for this.

I had unexpected results with this and I think I know why.

My array consists of 4 items (Categories) so 

$Cats->prepend( $Cats->eq(4) );

works until I hide the current Category. Essentially this means the array only consists of 3 Categories and the page throws an error.

That's only my guess. If I do $Cats->eq(3) etc or a lower number it works.

Worked for me. Thanks @Robin S

      I want to allow full text search on my site. There is a very nice solution that comes right out of the box:
      $selector = "title|body~=$q, limit=50"; This works, but to make it even better I would want to give higher weight to pages where the search term occurs in the title, than if it just occurs in the body. After all, a page with the title "Wine from France" is probably the best match for the search "france wine". How do I accomplish this in ProcessWire?
      I can see three possible paths, but I am not very fond of any of them:
      Do a direct SQL query, circumventing the API, along these lines. But I would prefer to abstract away the database layout if at all possible. Use something like ElasticSearch, but to be honest that would be to complicated to set up and maintain in the long run. Make multiple lookups, first for matches in the title, then for matches in the body, and merge and sort in PHP. My suspicion is that this would get complicated quite quickly. For instance, how do you deal with a page that has two of the three search terms in the title and the third in the body? Is there a magic option four I should look into? Or are any of the above options better than the others? Any input is welcome!

      Hi everyone 🙌
      Is there a way to order the language tabs in the backend? Currently, they seem to be ordered based on the created date (or id?) …
      ( time passes … ⏰ 🚶‍♂️)
      Just answered my own question. One can reorder the languages in the page tree under admin » languages or directly in the DB » pages » template_id=54 » sord field.
      Anyone knows if there are side effects when moving the default language from sort 0 to somewhere higher?

      Hi!
      I have two Page Reference fields: Category and Subcategory. Category is parent of Subcategory, and can have 0 to n Subcategories. Fields are selected by dropdown selection.
      I'm trying to achieve following logic:
      1. Select Category (obviously works)
      2. Change Subcategory options based on selected Category (this works)
      3. Hide the Subcategory field if Category has no Subcategories (to prevent weird dropdown with nothing to select)
      I have tried to investigate two possible alternatives to achieve step 3:
      A) Make dynamic condition into Subcategory selection's "Only visible if..." field
      B) Make a hook that fires when Category changes, then hides Subcategory field if Category has no children
      So far I haven't been successful in either. Conditions I've tried always lead to hidden field, and I haven't been able to find set up a hook that fires on field change.
      So here's the question (finally): Is there a way to alter field visibility in API, for example in ready.php or inside a hook? In API I could loop through categories, find the ones that have children and then make a selector based on their IDs.

      I'm working on a news feed that will show the most recent news in a full teaser grid, and all older news as a simpler archive-type list view. My selectors so far:
      $news_full = $page->children("template=news, limit={$page->feed_count_full}"); $news_archive = $page->children("template=news, start={$page->feed_count_full}, limit=9999"); The $page->feed_count_full field controls how many items to show in the teaser grid (I've confirmed it contains the correct value, and the $news_full selector works as intended).
      This works, but I don't like the limit in the second selector. Unfortunately, if I leave it out (i.e. I only specify a start, not a limit), the start is ignored and I get all news instead. Not a big problem as we will never have more than 9999 news, but it still bothers me, as semantically speaking I don't want to set a limit in this case.
      Is this the intended behaviour of start/limit selectors? Is there a cleaner way to specify an offset (start selector) without a limit?

      Thanks!

      I played with the Selectors object and would like to use it for a special use case...
      That is a custom Selectors object with dummy data converted to an php array to see the structure (Selectors object is a WireArray with "fields" added)
      Array ( [0] => Array ( [0] => Array ( [field] => seg1 [value] => val1 [not] => [group] => [quote] => [forceMatch] => ) [1] => Array ( [field] => seg2 [value] => val2 [not] => [group] => [quote] => [forceMatch] => ) ) )  
      But instead of "seg1" the field name is "field" with value "seg1" (= my field name).
       
      So I can't search the Selectors WireArray (= custom WireArray with added Selectors objects) with PW "find('seg1=val1')", Is there a way to search with "find()" or build a simple wrapper to make the elements searchable / filterable with find()?
