Debugging

Debugging --  DB_DataObject::debugLevel() ::debug()

DB_DataObject::debugLevel()

Sets the debugging level - so you can see the queries being built and executed

DB_DataObject::debugLevel ([int debug level])

Sets the debugging level (without any parameters it will disable the debugging output) See the configuration page for details on the various levels.

Beispiel 1. Setting the debugging level 

// turn debugging high
DB_DataObject::debugLevel(5);
$person = new DataObjects_Person;
$person->get(12);
$person->setFrom($_POST['input']);
$person->update();
// turn debugging off
DB_DataObject::debugLevel();

DB_DataObject::debug()

using the built in debug output of DB_DataObject

DB_DataObject::debug ([string message [, stringsubject [, int debug level]]])

Outputs data to the screen, to show you what is happening in the application.

Note that in production mode, the debugger is disabled.

Beispiel 2. Setting the debugging level 

$person = new DataObjects_Person;
$person->get(12);

// always prints
$person->debug('just got the person, about to set stuff', 'my application',0);
$person->setFrom($_POST['input']);

// only prints if debuglevel is set
$person->debug('just set the variables, about to update', 'my application',1);
$person->update();
