You might -wish to change this behavior once your development is complete. You'll find the <dfn>error_reporting()</dfn> -function located at the top of your main index.php file. Disabling error reporting will NOT prevent log files -from being written if there are errors.</p> - -<p>Unlike most systems in CodeIgniter, the error functions are simple procedural interfaces that are available -globally throughout the application. This approach permits error messages to get triggered without having to worry -about class/function scoping.</p> - -<p>The following functions let you generate errors:</p> - -<h2>show_error('<var>message</var>' [, int <var>$status_code</var>= 500 ] )</h2> -<p>This function will display the error message supplied to it using the following error template:</p> -<p><dfn>application/errors/</dfn><kbd>error_general.php</kbd></p> -<p>The optional parameter $status_code determines what HTTP status code should be sent with the error.</p> - -<h2>show_404('<var>page</var>' [, '<var>log_error</var>'])</h2> -<p>This function will display the 404 error message supplied to it using the following error template:</p> -<p><dfn>application/errors/</dfn><kbd>error_404.php</kbd></p> - -<p>The function expects the string passed to it to be the file path to the page that isn't found. -Note that CodeIgniter automatically shows 404 messages if controllers are not found.</p> - -<p>CodeIgniter automatically logs any show_404() calls. Setting the optional second parameter to FALSE will skip logging.</p> - - -<h2>log_message('<var>level</var>', '<samp>message</samp>')</h2> - -<p>This function lets you write messages to your log files. You must supply one of three "levels" -in the first parameter, indicating what type of message it is (debug, error, info), with the message -itself in the second parameter. Example:</p> - -<code> -if ($some_var == "")<br /> -{<br /> - log_message('error', 'Some variable did not contain a value.');<br /> -}<br /> -else<br /> -{<br /> - log_message('debug', 'Some variable was correctly set');<br /> -}<br /> -<br /> -log_message('info', 'The purpose of some variable is to provide some value.');<br /> -</code> - -<p>There are three message types:</p> - -<ol> -<li>Error Messages. These are actual errors, such as PHP errors or user errors.</li> -<li>Debug Messages. These are messages that assist in debugging. For example, if a class has been initialized, you could log this as debugging info.</li> -<li>Informational Messages. These are the lowest priority messages, simply giving information regarding some process. CodeIgniter doesn't natively generate any info messages but you may want to in your application.</li> -</ol> - - -<p class="important"><strong>Note:</strong> In order for the log file to actually be written, the - "logs" folder must be writable. In addition, you must set the "threshold" for logging in <dfn>application/config/config.php</dfn>. -You might, for example, only want error messages to be logged, and not the other two types. -If you set it to zero logging will be disabled.</p> - - - -</div> -<!-- END CONTENT --> - - -<div id="footer"> -<p> -Previous Topic: <a href="routing.html">URI Routing</a> - · -<a href="#top">Top of Page</a> · -<a href="../index.html">User Guide Home</a> · -Next Topic: <a href="caching.html">Page Caching</a> -</p> -<p><a href="http://codeigniter.com">CodeIgniter</a> · Copyright © 2006 - 2012 · <a href="http://ellislab.com/">EllisLab, Inc.</a></p> -</div> - -</body> -</html>
