Zen Cart主要文件详解Zen Cart main file detailed explanationAs the application_top.php in ZenCart system is theinitialization tasks, loading the configuration file forexample include ("includes/configure.php") ; , if not detectedin the file system will try to call the device file.

Then, it will take the initiative to traverse the configurationfile under include/extra_configures and include it.

After loading the next configuration file system is a veryimportant document, which led to the ZenCart and oscommercefeel very different causes, first invokes a require file("includes/initsystem.php") ;

In initsystem.php the first loadinginclude/auto_loaders/conf ig. core.php, conf ig. core.php is atwo round array$autoLoadConf ig, with an array of storage fileinformation for front file, then the system will then loadedthe include/auto_loaders directory of all the file name$loaderPrefix (default config) matching file.

The following program execution after the loading is activelyexecuting program require ("includes/autoload_func.php") ;here it will traverse the $autoLoadConfig array, which lasteffect will include all the necessary use may define functionclass, and variable initialization, the config.core.phpoutside of the obvious example

$autoLoadConf ig[0] [] =array ('autoType' ='c las s' , ' loadFi le'=' class.base.php ' ) ;

Outside the autoload_func.php executed after the effect isrequire (DIR_WS_CLASSES' class.base.php ' ) , the task is toinitialize the local big finish after including theinit_includes directory file, such as:

$autoLoadConf ig[110] [] = array ('autoType' = ' init_script' ,' loadFi le' = ' init_templates.php' ) ;

After executing the autoload_func.php file, it has loaded theinit_templates.php file under the init_includes directory.The above to explain how ZenCart is in accordance with the touchversion of the content displayed.

In the twenty-ninth line of index.php, there is a sentence$directory_array = $template->get_template_part

($code_page_directory, ` /^header_php/ ' ) ;

Since all initialization tasks havebeen completed, we can thenfind their definitions in the following files, such as$autoLoadConf ig[100] [] = array ('autoType' =

' classInstant iate' , 'c las sName' = 'template_func' ,

'obj ectName' = ' template' ) ;

Here is the definition of the $template = new (template_func,$code_page_directory) ; and the definition of variables isdefined here must be defined on the template_func class inclass/template_func.php more familiar with theinit_includes/init_sanitize.php file, in this kind of

important definition of the get_template_dir two approach(get_template_part) and () ;

These two approaches play a deterministic role in the use ofzencart templates.

Get_template_dir function get_template_dir ($template_code,$current_template, $current_page, $template_dir,

$debug=false) , which defines 5 parameters, the first parameteris the common name, it is this file used to form two parameterdiscriminationafter directoryhas nomatching$template_code,the transcript of the acquiescence of system functionfile_exists so many beginners can have doubts

Function, get_template_dir ($template_code,

$current_template, $current_page, $template_dir,

$debug=fal se) {

//echo 'template_default/' . $template_dir. '=' .

$template_code;

If ($this->file_exists ($current_template, $current_page,$template_code)) {

Return $current_template. $current_page. \ / \ ";

}elseif ($thi s->file_exists (DIR_WS_TEMPLATES) ,template_default/, $current_page, ereg_replace (` / ' , ' , ' , '$template_code ' ) , $debug)) {

Return DIR_WS_TEMPLATES. ' template_default/' . $current_page;

} elseif ($this->file_exists ($current_template,

$template_dir, $template_code, ereg_replace (` /' , ' , ' , ' , ' , '$debug ' )) {

Return $current_template. $template_dir;

} else {

Return DIR_WS_TEMPLATES. 'template_default/' . $template_dir;//return $current_template. $template_dir;

}

}

(get_template_part) method has two functions, the firstparameter is the file directory, the second parameter is thematching requirements, implementation is the consequence ofincluding the directory of all the required document file namematching

For example, $directory_array = $template->get_template_part($code_page_directory, '/^header_php/' ) ;

This sentence is to enforce the consequences of all

$code_page_directory directory under the file name toheader_php off the file

The URL (http://localhost/zencart/index.php,main_page=product_info&cPath=49_27&products_id=83) at thistime?

When you should check the definition of init_sanitize.php in$code_page_directory, the value of $code_page_directory atthis time should be includes/modules/product_info/

Therefore, it should be included in the directory to mop up allheader_php files, in here it seems only a header_php.phpdirectory_array美元=模板-> get_template_part美元美元code_page_directory / ^ header_php /” 这个包括文件实际上是初始化前台不同页面显示所需求用到的变量函数重要是初始化数据库的东西 由于每个页面需求的数据材料都有能够不同 因此index.php main_page=指数当main_page的值不同是在包括/模块/目录下都会有个相应的目录这里是指数目录

程序会顺次在

这四个目录下找html_header。 PHP在这里最后在

到这里就能够本身写摸板文件了美元 由于模板->get_template_dir()是按顺序找的因此你只需在你的模板文件中存在该文件便可
