Add the phpcms template mechanism to CodeIgniter _ PHP Tutorial

Add the phpcms template mechanism to CodeIgniter. CodeIgniter is suitable for application development on small sites, but its built-in view function may cause troubles for front-end personnel who do not understand PHP. In contrast, the view template parsing of phpcms is much more powerful, and CodeIgniter is suitable for small site application development. However, its built-in view function may cause trouble for front-end personnel who do not understand PHP. In contrast, the view template parsing of phpcms is much more powerful, so the template parsing function of PHPCMS is removed here and added to PHPCMS.

First, add template_cache.php to CodeIgniter libraries.

Is_array ($ string) return addslashes ($ string); foreach ($ string as $ key => $ val) $ string [$ key] = new_addslashes ($ val ); return $ string ;}}

Then add a template function in global_helper.

If (! Function_exists ('Template ')) {/*** template call ** @ 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; // address for generating the compilation template $ compiledtplfile = $ template_cache-> cache_path.DIRECTORY_SEPARATOR. 'caches _ template '. DIRECTORY_SEPARATOR. $ style. DIRECTORY_SEPARATOR. $ module. DIRECTORY_SEPARATOR. $ template. EXT; // view file $ tplfile = APPPATH. 'view '. DIRECTORY_SEPARATOR. $ module. DIRECTORY_SEPARATOR. $ template. EX T; if (file_exists ($ tplfile) {if (! File_exists ($ compiledtplfile) | (@ filemtime ($ tplfile)> @ filemtime ($ compiledtplfile) {$ template_cache-> template_compile ($ module, $ template, $ style) ;}} else {// If not, retrieve 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, 500, '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 add a method in MY_Controller.php.

/*** Automatic template call ** @ 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 );}

In this way, you can directly use the phpcms template syntax.
