Get child pages but put child 4 first

[Peter Knight]

<?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?

It's the infinitely useful Console panel in Tracy Debugger: https://adrianbj.github.io/TracyDebugger/#/debug-bar?id=console

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
