right now I have:
$image = get_field('image');
If I var_dump($image);
Data returned will look like this:
Array
(
[id] => 540
[alt] => A Movie
[title] => Movie Poster: UP
[caption] => sweet image
[description] => a man and a baloon
[url] => http://localhost:8888/acf/up.jpg
)
If I want to access the title I would do:
$image['title'];
what if I want to access it directly wiithout a variable like:
get_field('image')['title'];
is it possible?
Pasted directly from the manual:
As of PHP 5.4 it is possible to array dereference the result of a function or method call directly. Before it was only possible using a temporary variable.
As of PHP 5.5 it is possible to array dereference an array literal.
Example #7 Array dereferencing
<?php
function getArray() {
return array(1, 2, 3);
}
// on PHP 5.4
$secondElement = getArray()[1];
// previously
$tmp = getArray();
$secondElement = $tmp[1];
// or
list(, $secondElement) = getArray();
?>
So yes - you can - but you need PHP 5.4+
As far as I know it is possible since PHP 5.4.
http://php.net/manual/en/migration54.new-features.php (check for point number 3)
All you have to do is just update version of you php :)
You said object, but your example is an array.
Anyway it's called array dereference, and as Jari said has been possible since php 5.4.
