unique array

[webhoes]

I am trying to get an unique array with this code

$voedsel = Array();
$voedsel = $pages->find("template=schildpad, schildpad_caresheet=$page->title")->id;
$result = array_unique($voedsel);

For array_unique I get the following error in Tracy: 

PHP Warning: array_unique() expects parameter 1 to be array, object given in...

 

I want to put the unique array in a custom function that makes a list with an image and title.

 

What am I doing wrong?

Hi @webhoes

You can do it in several ways

$arr = $pages->find()->getArray();
$result = array_unique($arr);

or

$arr = $pages->find()->unique();

https://processwire.com/api/ref/wirearray/unique/

$pages->find() method returns a filtered PageArray unless an include mode is specified.
