Question

How can I write this IF condition (at the moment I have error, but I don’t know where)?

$gll_name = ($gll_id != NULL ? $w = $this->gallery_model->gallery_get_one_user($gll_id);  $w->name : " ");

You do not need two variables, also “shorthand ifs” do not allow colons. This should work:

$gll_name = (
    $gll_id != NULL
    ? $this->gallery_model->gallery_get_one_user($gll_id)->name
    : " "); 

(note that I have added indents for visibility, they do not matter in PHP in this case)

Also consider strict conditions (using !== instead of !=), as PHP will treat all false-ish values (null, false, 0 etc.) as being equal (==) to NULL, but only NULL is strictly equal (===) to NULL. For a demonstration see: http://ideone.com/8ENsX
