CodeIgniter using Phpcms template engine _php Tutorial

CodeIgniter is ideal for small-site application development, but its own view features may cause problems for front-end people who do not understand PHP. In contrast phpcms view template parsing is much more powerful, so here the Phpcms template parsing function stripped out, add to Phpcms.
First, add template_cache.php to the CodeIgniter libraries
Copy CodeThe code is as follows:
/**
* Template Parsing cache
*/
Final class Template_cache {

Public $cache _path;
Public Function __construct ()
{
$CI =& get_instance ();
$this->cache_path = APPPATH. ' Views ';
}

/**
* Compile Template
*
* @param $module Module name
* @param $template Template file name
* @param $istag is a label template
* @return Unknown
*/

Public Function Template_compile ($module, $template, $style = ' default ') {

$tplfile = APPPATH. ' Views '. Directory_separator. $module. Directory_separator. $template. PHP ';

if (! file_exists ($tplfile)) {
Show_error ($tplfile, $, ' Template does not exist (1) ');
}

$content = @file_get_contents ($tplfile);

$filepath = $this->cache_path. Directory_separator. ' Caches_template '. Directory_separator. $style. Directory_separator. $module. Directory_separator;


if (!is_dir ($filepath)) {
mkdir ($filepath, 0777, true);
}
$compiledtplfile = $filepath. $template. PHP ';
$content = $this->template_parse ($content);
$strlen = File_put_contents ($compiledtplfile, $content);
chmod ($compiledtplfile, 0777);
return $strlen;
}

/**

*/
Public Function Template_refresh ($tplfile, $compiledtplfile) {
$str = @file_get_contents ($tplfile);

Then add a template function to the Global_helper
Copy CodeThe code is as follows:
if (! function_exists (' template '))
{
/**
* Template Invocation
*
* @param $module
* @param $template
* @param $istag
* @return Unknown_type
*/
function template ($module = ' Expatree ', $template = ' index ', $style = ' Expatree ', $return _full_path=true) {
Global $CI;
if (!isset ($CI)) $CI =& get_instance ();
if (! $style) $style = ' default ';
$CI->load->library (' Template_cache ', ' Template_cache ');
$template _cache = $CI->template_cache;
Compile the template to generate the address
$compiledtplfile = $template _cache->cache_path. Directory_separator. ' Caches_template '. Directory_separator. $style. Directory_separator. $module. Directory_separator. $template. EXT;
View File
$tplfile = APPPATH. ' Views '. Directory_separator. $module. Directory_separator. $template. EXT;
if (file_exists ($tplfile)) {
if (!file_exists ($compiledtplfile) | | (@filemtime ($tplfile) > @filemtime ($compiledtplfile)) {
$template _cache->template_compile ($module, $template, $style);
}
} else {
If not, adjust the default style template
$compiledtplfile = $template _cache->cache_path. Directory_separator. ' Caches_template '. Directory_separator. ' Default '. Directory_separator. $module. Directory_separator. $template. EXT;
if (!file_exists ($compiledtplfile) | | (File_exists ($tplfile) && filemtime ($tplfile) > Filemtime ($compiledtplfile)) {
$template _cache->template_compile ($module, $template, ' Default ');
} elseif (!file_exists ($tplfile)) {
Show_error ($tplfile, $, ' Template does not exist (0) ');
}
}

if ($return _full_path)
return $compiledtplfile;
Else
Return ' Caches_template '. Directory_separator. $style. Directory_separator. $module. Directory_separator. $template;
}
}

Then in my_controller.php, add a method
Copy the Code code as follows:
/**
* Automatic template invocation
*
* @param $module
* @param $template
* @param $istag
* @return Unknown_type
*/
protected function View ($view _file, $page _data=false, $cache =false)
{
$view _file= $this->template ($this->page_data[' Controller_name '). $this->page_data[' module_name '], $view _ file);

$this->load->view ($view _file, $page _data);
}

This is basically done, you can directly phpcms the template syntax.
