  • Debugging PHP Code

    For those that may not be aware, the following is really useful when debugging PHP code:

    Code:
    $GLOBALS['log']->debug('Here is my variable:', [$variable]);
    You just need to ensure that in your `data\config.php`, the relevant logging `level` is enabled for your output:

    Code:
    'logger' => [
            'path' => 'data/logs/espo.log',
            'level' => 'DEBUG',
            'rotation' => true,
            'maxFileNumber' => 30
        ],
    Then you just need to check your log file (in the above path) for the messages. This has helped us massively!

    Available options are:

    Code:
    DEBUG
    INFO
    NOTICE
    WARNING
    ERROR
    CRITICAL

    Thanks blueprint I am currently struggling with a PHP stupid bug. Sorry if this is quite obvious but in which script do I write
    Code:
     
     $GLOBALS['log']->debug('Here is my variable:', [$variable]);
    ?

      That all depends which script is causing you the issue.

      For example, I've recently been debugging some hooks so I've added the above code a number of times in the `beforeSave` function.

      I've also previously littered the majority of the ORM php files with debug statements just so I could figure out the program flow.

        Thanks so much, it's like using "console.log" to debug javascript, excellent !
