fields render

[jeremie]

Hi,

sorry for the very nubby question

but i can't understand why 

<?php echo $page->categories; ?>

renders me 1041 instead of the name of the categorie I define

categories being the name of the field I define

thanks for your help

Hi,

that is ok. because ProcessWire by default in that case return Page ID (response from __toString() method inside Page class).
And, as example to get page "title" append field name:

echo $page->category->title;

If it is array of pages you can iterate:

foreach($page->categories as $category){
    echo $category->title;
}

There are also many other options inside PW api, and as example, to get single Page item inside Pages you can get it by index:

// get first category title 
$n = 0;
echo $page->categories->eq($n)->title;

More about Page or Pages.
Regards.

Thank you very much for your answer.

strangely 

echo $page->category->title;

doesn't seem to work but the last example works perfectly

That would seem to be because your "categories" field is a Page field configured for multiple pages? If that is the case, it's normal that the "categories" property wouldn't have at title property itself, because it outputs as PageArray.
