It is -also responsible for <a href="../general/caching.html">caching</a> your web pages, if you use that feature.</p> - -<p class="important"><strong>Note:</strong> This class is initialized automatically by the system so there is no need to do it manually.</p> - -<p>Under normal circumstances you won't even notice the Output class since it works transparently without your intervention. -For example, when you use the <a href="../libraries/loader.html">Loader</a> class to load a view file, it's automatically -passed to the Output class, which will be called automatically by CodeIgniter at the end of system execution. -It is possible, however, for you to manually intervene with the output if you need to, using either of the two following functions:</p> - -<h2>$this->output->set_output();</h2> - -<p>Permits you to manually set the final output string. Usage example:</p> - -<code>$this->output->set_output($data);</code> - -<p><strong>Important:</strong> If you do set your output manually, it must be the last thing done in the function you call it from. -For example, if you build a page in one of your controller functions, don't set the output until the end.</p> - - -<h2>$this->output->set_content_type();</h2> - -<p>Permits you to set the mime-type of your page so you can serve JSON data, JPEG's, XML, etc easily.</p> - -<code>$this->output<br /> - ->set_content_type('application/json')<br /> - ->set_output(json_encode(array('foo' => 'bar')));<br /> -<br /> -$this->output<br /> - ->set_content_type('jpeg') // You could also use ".jpeg" which will have the full stop removed before looking in config/mimes.php<br /> - ->set_output(file_get_contents('files/something.jpg'));</code> - -<p><strong>Important:</strong> Make sure any non-mime string you pass to this method exists in config/mimes.php or it will have no effect.</p> - - -<h2>$this->output->get_output();</h2> - -<p>Permits you to manually retrieve any output that has been sent for storage in the output class. Usage example:</p> -<code>$string = $this->output->get_output();</code> - -<p>Note that data will only be retrievable from this function if it has been previously sent to the output class by one of the -CodeIgniter functions like <var>$this->load->view()</var>.</p> - - -<h2>$this->output->append_output();</h2> - -<p>Appends data onto the output string. Usage example:</p> - -<code>$this->output->append_output($data);</code> - - - -<h2>$this->output->set_header();</h2> - -<p>Permits you to manually set server headers, which the output class will send for you when outputting the final rendered display. Example:</p> - -<code> -$this->output->set_header("HTTP/1.0 200 OK");<br /> -$this->output->set_header("HTTP/1.1 200 OK");<br /> -$this->output->set_header('Last-Modified: '.gmdate('D, d M Y H:i:s', $last_update).' GMT');<br /> -$this->output->set_header("Cache-Control: no-store, no-cache, must-revalidate");<br /> -$this->output->set_header("Cache-Control: post-check=0, pre-check=0");<br /> -$this->output->set_header("Pragma: no-cache"); </code> - - -<h2>$this->output->set_status_header(<var>code</var>, '<var>text</var>');</h2> - -<p>Permits you to manually set a server status header. Example:</p> - -<code>$this->output->set_status_header('401');<br /> -// Sets the header as: Unauthorized</code> - -<p><a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html">See here</a> for a full list of headers.</p> - -<h2>$this->output->enable_profiler();</h2> - -<p>Permits you to enable/disable the <a href="../general/profiling.html">Profiler</a>, which will display benchmark and other data -at the bottom of your pages for debugging and optimization purposes.</p> - -<p>To enable the profiler place the following function anywhere within your <a href="../general/controllers.html">Controller</a> functions:</p> -<code>$this->output->enable_profiler(TRUE);</code> - -<p>When enabled a report will be generated and inserted at the bottom of your pages.</p> - -<p>To disable the profiler you will use:</p> -<code>$this->output->enable_profiler(FALSE);</code> - -<h2>$this->output->set_profiler_sections();</h2> - -<p>Permits you to enable/disable specific sections of the Profiler when enabled. Please refer to the <a href="../general/profiling.html">Profiler</a> documentation for further information.</p> - -<h2>$this->output->cache();</h2> -<p>The CodeIgniter output library also controls caching. For more information, please see the <a href="../general/caching.html">caching documentation</a>.</p> - -<h2>Parsing Execution Variables</h2> - - <p>CodeIgniter will parse the pseudo-variables <var>{elapsed_time}</var> and <var>{memory_usage}</var> in your output by default. To disable this, set the <var>$parse_exec_vars</var> class property to <var>FALSE</var> in your controller. - - <code>$this->output->parse_exec_vars = FALSE;</code> - -</div> -<!-- END CONTENT --> - - -<div id="footer"> -<p> -Previous Topic: <a href="language.html">Language Class</a> - · -<a href="#top">Top of Page</a> · -<a href="../index.html">User Guide Home</a> · -Next Topic: <a href="pagination.html">Pagination Class</a> -</p> -<p><a href="http://codeigniter.com">CodeIgniter</a> · Copyright © 2006 - 2011 · <a href="http://ellislab.com/">EllisLab, Inc.</a></p> -</div> - -</body> -</html> |
