Hi, I want have this code (below), how would I check if a user is logged in?  I want to make it so they can only see 500 chars, or the full thing if they're logged in.  Thanks! 

  public function __construct( $data=array() ) {
    if ( isset( $data['id'] ) ) $this->id = (int) $data['id'];
    if ( isset( $data['publicationDate'] ) ) $this->publicationDate = (int) $data['publicationDate'];
    if ( isset( $data['title'] ) ) $this->title = preg_replace ( "/[^\.\,\-\_\'\"\@\?\!\:\$ a-zA-Z0-9()]/", "", $data['title'] );
    if ( isset( $data['summary'] ) ) $this->summary = preg_replace ( "/[^\.\,\-\_\'\"\@\?\!\:\$ a-zA-Z0-9()]/", "", $data['summary'] );
    if ( isset( $data['content'] ) ) $this->content = $data['content'];
if ( isset( $data['tags'] ) ) $this->tags = $data['tags'];
  }

Whoops.  didn't mention where I wanted it.  I want it in the content section.  I put if($user -> uid.... then if I put an else statement beneath, would that work?

depends on what user->uid is

 

try it, see what happens. if it doesn't work, provide more details
