mysqli prepare() wont return errors

[Agony]

So im trying to set up error handling for the:

$result = $db->prepare($this->query);

However - if i break the input query, all i get is NULL - no error from prepare.

if i var_dump ($result) - its NULL, If i var_dump() the returned $db->prepare($this->query) - its also all NULL - no errors or anything.

object(mysqli)[2]  public 'affected_rows' => null  public 'client_info' => null  public 'client_version' => null  public 'connect_errno' => null  public 'connect_error' => null  public 'errno' => null  public 'error' => null  public 'error_list' => null  public 'field_count' => null  public 'host_info' => null  public 'info' => null  public 'insert_id' => null  public 'server_info' => null  public 'server_version' => null  public 'stat' => null  public 'sqlstate' => null  public 'protocol_version' => null  public 'thread_id' => null  public 'warning_count' => null

Query is:

"UPDATE SELECT * FROM posts" 

so that's clearly wrong and should fail.

How am i supposed to catch any query caused errors from it?

I think errors might not show up until you actually execute the query.

EDIT:

 

Apparently prepare always returns false according to the manual.. which sucks.

 

Guess just gotta write custom message as an error.
