phpJobScheduler is designed to automate tasks by
scheduling PHP scripts to run at set intervals.
This version runs silently (no screen output) but saves the output, including any errors, to the database.
Full details can be found at: www.phpjobscheduler.co.uk
To upgrade an existing installation: there are TWO main points to note!
Your existing scheduled tasks, if any exist,
will remain unchanged within your database.
Also, you can retain your existing config file: /phpjobscheduler/pjsfiles/config.inc.php
If you have previously made changes to: /phpjobscheduler/pjsfiles/constants.inc.php
then you will need to make those changes again as this file now contains many new constants.
When you have followed the details below (To complete a new
installation) you MUST login to check your scheduled tasks, by
doing so it will automatically update your database and add the required new fields to the
tables as required.
To complete a new installation:
<?php include( dirname(__FILE__) . "/phpjobscheduler/firepjs.php"); ?>
The above HTML can be added to any web page on any website (not just to the site where phpJobScheduler is installed). Adding this code will add a very small clear image to your page - invisible (unless you know its there). Execution is very quick so will not slow the loading of any pages.
If you have correctly completed the above the following tables will be created in your database database:
Error log - recording of runs and errors of each fired task.
Recorded data: date of last run, and url including errors if any occur. If "Output:" has no data then this means the script ran without errors or output.
By default error logging is turned on (TRUE). To turn on/off error logs:
Change the value assigned to ERROR_LOG within the /pjsfiles/constants.inc.php file. Change the value to FALSE to stop logging. It will not affect the running of fired scripts if you turn off error logging.
The output is truncated to a maximum length of 1200 characters by default to ensure the logs table does not become too large. You can change this by editing the constant MAX_ERROR_LOG_LENGTH within the constants.inc.php file.
Altering the time frame window
This can be changed by altering the value assigned to TIME_WINDOW within the /pjsfiles/constants.inc.php file. The default value is 3600 seconds (60 minutes which should suffice for most sites). This means that when the firing engine (phpjobscheduler/firepjs.php) is called any scheduled job having a fire time within 60 minutes will be executed.
You can increase or decrease the default value of the time frame window. If your site receives just a few hits per day you should consider increasing the value to 43200 (12 hours).
If your site ALWAYS receives several hits per hour or more then you should consider reducing the value to suit your needs.

DEBUG - for testing
When you are happy all is running without error set DEBUG to false, edit the file:
This will then prevent any output - so when you call firejps.php it will run silently.
