| Description | http://forums.web2project.net/viewtopic.php?p=13826#13826 Pacek wrote: I have problem with "Print to PDF" function. When I press button I have error which is displayed at the bottom of Gantt chart: Code: JpGraph Error General PHP error : Undefined variable: criticalTasks Could you help me resolve this error? After installing XAMPP for Win on my local VISTA maschine I got the same error and the Gantt-chart is not generated. The same web2project installed before by a free hoster did never get such an error message. A sign that some hardware and /or software setup have an impact to the correct operation of the SW. After some debuging I figured out that it can be circumvented by setting: copy from my php.ini: ; Store the last error/warning message in $php_errormsg (boolean). Setting this value ; to On can assist in debugging and is appropriate for development servers. It should ; however be disabled on production servers. ; Default Value: Off ; Development Value: On ; Production Value: Off ; http://php.net/track-errors track_errors = Off As the standard setting was "on" the switch off removes the error. The error comes from a php-error handling routine in "jpgraph.php" and is catched by the php error message 'php_errormsg', that reports an "unknown string local_char_set". // //Check if there were any warnings, perhaps some wrong includes by the user // if( isset($GLOBALS['php_errormsg']) && CATCH_PHPERRMSG && !preg_match('|Deprecated|', $GLOBALS['php_errormsg']) && !preg_match('|deprecated|', $GLOBALS['php_errormsg']) && !preg_match('|Non-static|', $GLOBALS['php_errormsg'])) { JpGraphError::RaiseL(25004,$GLOBALS['php_errormsg']); } Why this php-error is generated I dont know... A task for the experts. With track_errors=off the php-error is not anymore reported and 'php_errormsg' becomes "NULL", so the php-error is not handled this code: JpGraphError::RaiseL(25004,$GLOBALS['php_errormsg']); gives the text-message: JpGraph Error General PHP error : Undefined variable: criticalTasks. Interesting to see, that 2 different installations with a mini-change in the php.ini can give completely different results. The best solution would to keep the error tracking on and to figure out why the php-error occurs, otherwise it is only a dirty solution. | ||||||||
| Additional Information | all versions as bug/error-handling in "jpgraph.php" depend on settings of php.ini | ||||||||
