vtiger debug 调试错误

vtiger 5.2.0 的调试

数据库调试，在需要的页面，加入以下代码即可 

global $adb;
$adb->setDebug(true);

  打开log日志调试

1.先找到config.performance.php  把 'LOG4PHP_DEBUG' => false改为 'LOG4PHP_DEBUG' => true

2.找到log4php.properties，把log4php.rootLogger=FATAL,A1 改为log4php.rootLogger=INFO,A1

以前版本的调试看这里

PHP Files (*.php)

1. To print all the SQL commands to the browser.
   In include/database/PearDatabase.php near line 680 replace:

   //$this->database->debug = true;

   with:

   $this->database->debug = true;

2. To print DEBUG log data to the logfile logs/vtigercrm.log.
   In log4php.properties replace:

   log4php.rootLogger=FATAL,A1

   with:

   log4php.rootLogger=DEBUG,A1

3. To print a value (or array) to the browser, insert the following in the PHP file:
   

   trigger_error('TempDebug: $someVariable="' 
                .print_r($someVariable, TRUE) .'"');

   Don't forget to remove it afterward! :-)

4. Better still, to print an array to the browser in a more legible format we add opening and closing HTML

    tags: 

   trigger_error('TempDebug: $smallArray=

   "' 
                 .print_r($smallArray, TRUE) .'"

   '); Note however that trigger_error() truncates the output if the array is large. The following works on large arrays:

   trigger_error('TempDebug: $largeArray:...'); 
   print_r("

   ");
   print_r($largeArray);
   print_r("

   ");

Smarty Templates (*.tpl)

Smarty templates are used to programatically create HTML pages.

1. To list all the data available to a Smarty template in a separate browser window:
   In /Smarty/libs/Smarty.class.php near line 104 replace:

   var $debugging       =  false;

   with:

   var $debugging       =  true;

2. In a Smarty template data can be "printed" into an HTML comment and then viewed by selecting View->Page Source in your browser. This example shows some of the parameters "passed" from PHP code to a Smarty template:

AJAX and JavaScript (*.js)

Warning: Changes in AJAX code may require matching changes in Smarty code!

1. To print a value (or array) to a brower message box, insert the following in the JavaScript file:

   alert('TempDebug: someVariable = "' +someVariable +'"');

2. A JavaScript debugger is available for Firefox, Mozilla, Netscape [1].
