FirePHP Integration

FirePHP (http://www.firephp.org/ and http://www.firephp.org/HQ/Use.htm) enables you to log to your Firebug Console using a simple PHP method call. All data is sent via response headers and will not interfere with the content on your page. FirePHP is ideally suited for AJAX development where clean JSON and XML responses are required.

*** Note: Work with PHP 5 only ***

Requirements

FireFox?
FireBug? add-on https://addons.mozilla.org/en-US/firefox/addon/1843
FirePHP add-on https://addons.mozilla.org/en-US/firefox/addon/6149

Installation

1. Get FirePHP Core library http://www.firephp.org/DownloadRelease/FirePHPLibrary-FirePHPCore-0.2.1
   
2. Copy the contents of FirePHPCore-0.2.1/lib/ into {seagull}/lib/other the result should be:
   

lib/other/FirePHPCore with fb.php, FirePHP.class.php, and LICENSE

Wrapper Class

Currently there is no customization of the FirePHP class, but this 'wrapper' class will allow for future customization if it is required.

require_once 'other/FirePHPCore/FirePHP.class.php';

class SGL_FirePhp extends FirePHP 
{
    
}

default/classes/ConfigMgr.php

Add a new log type of 'firephp'

$this->aLogTypes = array(
            'file' => 'file',
            'mcal' => 'mcal',
            'sql' => 'sql',
            'syslog' => 'syslog',
            'firephp' => 'firephp',
            );

Integration Points

SGL::logMessages()

If the log type is set to 'firephp' then ...

if (!empty($conf['log']['type']) && $conf['log']['type'] == 'firephp' && version_compare(phpversion(), '5.0.0') >= 0) {
    require_once SGL_CORE_DIR . '/FirePhp.php';
    $logger = SGL_FirePhp::getInstance(true);
            
    // Disable logging for live sites
    if(!empty($conf['debug']['production']) && $conf['debug']['production']) {
        $logger->setEnabled(false);
    }            
} else {
    include_once 'Log.php';
            
    // Instantiate a logger object based on logging options
    $logger = & Log::singleton($conf['log']['type'],
                $logName,
                $conf['log']['ident'],
                array(  $conf['log']['paramsUsername'],
                        $conf['log']['paramsPassword'],
                       'dsn' => $dsn
                ));
}

ErrorHandler?

If FirePHP is enabled then use the CLI error output format and output the error message to the FireBug? Console.

if (SGL::runningFromCLI() || 
    (!empty($conf['log']['type']) && 
    $conf['log']['type'] == 'firephp' && 
    version_compare(phpversion(), '5.0.0') >= 0)) {
    $output = <<<EOL
MESSAGE: $errStr
TYPE: {$this->errorType[$errNo][0]}
FILE: $file
LINE: $line

 --
EOL;
}

if (!empty($conf['log']['showErrors']) && $conf['log']['showErrors'] == true) {
    if (!empty($conf['log']['type']) && 
        $conf['log']['type'] == 'firephp' && 
        version_compare(phpversion(), '5.0.0') >= 0) {
        require_once SGL_CORE_DIR . '/FirePhp.php';
        $logger = SGL_FirePhp::getInstance(true);
        $logger->log($output);
    } else {
        echo $output;
    }
}

Manager

FirePHP can also be used for debugging. Instead of using echo to provide a quick way to output variable values, etc. FirePHP can be used to output those values to the console

require_once SGL_CORE_DIR . '/FirePhp.php';

In the Managers constructor add something like this

$this->firePhp = SGL_FirePhp::getInstance(true);

// Disable logging for live sites
if($this->conf['debug']['production']) {
    $this->firePhp->setEnabled(false);
}

Then in the _cmd_foo() method

$this->firePhp->log('Plain Message');
$this->firePhp->info('Info Message');
$this->firePhp->warn('Warn Message');
$this->firePhp->error('Error Message');

$this->firePhp->dump('Key', $variable);

Settings to enable FirePHP logging:

debug - production = false
debug - show errors = true
log - type = firephp
log - enabled = true
