Codeigniter generates static pages_PHP tutorial-PHP Tutorial-php.cn

Using CI to generate static pages is actually very simple. Just like what is said in the forum, read the data in the page, write it into the html file, and finally display the html file. Okay, let’s code it.

[php]

class MY_Loader extends CI_Loader {

public function m_view($view, $vars = array(), $return = FALSE){

Return $this->_m_ci_load(array('_ci_view' => $view, '_ci_vars' => $this->_ci_object_to_array($vars), '_ci_return' => $return));

}

protected function _m_ci_load($_ci_data){

.....

$_ci_html_file=($_ci_ext==='')? $_ci_view.".html" : $_ci_view;//This, the file name of the generated static page

foreach ($this->_ci_view_paths as $_ci_view_file => $cascade){

if (file_exists($_ci_view_file.$_ci_file)){

$_ci_path = $_ci_view_file.$_ci_file;

$_ci_html_path=$_ci_view_file.$_ci_html_file;//The path to generate static pages

$file_exists = TRUE;

break;

}

…

}

} }

.....

//Here

if(config_item("html")===TRUE){//Whether to enable generating static pages

$_html_file=@fopen($_ci_html_path,'r');//Create .html file

$buffer = ob_get_contents();

@ob_end_clean();

$_html_file=@fopen($_ci_html_path,'w');

flock($_html_file, LOCK_EX);

flock($_html_file, LOCK_UN);

fclose($_html_file);

}

//echo(filesize($_ci_html_path)."-".strlen($buffer));

include($_ci_html_path);

} }

…

}

class MY_Loader extends CI_Loader {

public function m_view($view, $vars = array(), $return = FALSE){

return $this->_m_ci_load(array('_ci_view' => $view, '_ci_vars' => $this->_ci_object_to_array($vars), '_ci_return' => $return));

}

protected function _m_ci_load($_ci_data){

.....

$_ci_html_file=($_ci_ext==='')? $_ci_view.".html" : $_ci_view;//这,生成静态页面的文件名

foreach ($this->_ci_view_paths as $_ci_view_file => $cascade){

if (file_exists($_ci_view_file.$_ci_file)){

$_ci_path = $_ci_view_file.$_ci_file;

$_ci_html_path=$_ci_view_file.$_ci_html_file;//生成静态页面的路径

$file_exists = TRUE;

break;

}

......

}

.......

//在这

if(config_item("html")===TRUE){//是否开启生成静态页面

$_html_file=@fopen($_ci_html_path,'r');//创建.html文件

$buffer = ob_get_contents();

@ob_end_clean();

if(!$_html_file||(@filesize($_ci_html_path)!=strlen($buffer))){ //如果文件不存在或文件已更变

$_html_file=@fopen($_ci_html_path,'w');

flock($_html_file, LOCK_EX);

fwrite($_html_file, $buffer);

flock($_html_file, LOCK_UN);

fclose($_html_file);

}

//echo(filesize($_ci_html_path)."-".strlen($buffer));

include($_ci_html_path);

}

......

}

}调用

[html]

$this->load->m_view('login',$datas);

是否生成HTML文件

$config["html"] = TRUE;

全部代码如下

[php]

class MY_Loader extends CI_Loader {

public function m_view($view, $vars = array(), $return = FALSE){

return $this->_m_ci_load(array('_ci_view' => $view, '_ci_vars' => $this->_ci_object_to_array($vars), '_ci_return' => $return));

}

protected function _m_ci_load($_ci_data){

// Set the default data variables

foreach (array('_ci_view', '_ci_vars', '_ci_path', '_ci_return') as $_ci_val){

$$_ci_val = isset($_ci_data[$_ci_val]) ? $_ci_data[$_ci_val] : FALSE;

} }

$file_exists = FALSE;

// Set the path to the requested file

if (is_string($_ci_path) && $_ci_path !== ''){

$_ci_x = explode('/', $_ci_path);//Use one string to split another string

$_ci_file = end($_ci_x);//Point the internal pointer of the array to the last unit

}else{

$_ci_ext = pathinfo($_ci_view, PATHINFO_EXTENSION);// Return file path information

$_ci_file = ($_ci_ext === '') ? $_ci_view.'.php' : $_ci_view;

$_ci_html_file=($_ci_ext==='')? $_ci_view.".html" : $_ci_view;//This, the file name of the generated static page

foreach ($this->_ci_view_paths as $_ci_view_file => $cascade){

if (file_exists($_ci_view_file.$_ci_file)){

$_ci_path = $_ci_view_file.$_ci_file;

$_ci_html_path=$_ci_view_file.$_ci_html_file;//The path to generate static pages

$file_exists = TRUE;

break;

}

if ( ! $cascade){

break;

}

} }

if ( ! $file_exists && ! file_exists($_ci_path))

{

show_error('Unable to load the requested file: '.$_ci_file);

} }

// This allows anything loaded using $this->load (views, files, etc.)

// to become accessible from within the Controller and Model functions.

$_ci_CI =& get_instance();

foreach (get_object_vars($_ci_CI) as $_ci_key => $_ci_var)

{

if ( ! isset($this->$_ci_key))

$this->$_ci_key =& $_ci_CI->$_ci_key;

}

} }

* Extract and cache variables

* *

* You can either set variables using the dedicated $this->load->vars()

* function or via the second parameter of this function. We'll merge

* the two types and cache them so that views that are embedded within

* other views can have access to these variables.

if (is_array($_ci_vars))

{

$this->_ci_cached_vars = array_merge($this->_ci_cached_vars, $_ci_vars);

}

extract($this->_ci_cached_vars);

* Buffer the output

* We buffer the output for two reasons:

* 1. Speed. You get a significant speed boost.

* 2. So that the final rendered template can be post-processed by

* the output class. Why do we need post processing? For one thing,

* in order to show the elapsed page load time. Unless we can

* intercept the content right before it's sent to the browser and

* then stop the timer it won't be accurate.

ob_start();

// If the PHP installation does not support short tags we'll

// do a little string replacement, changing the short tags

// to standard PHP echo statements.

if ( ! is_php('5.4') && (bool) @ini_get('short_open_tag') === FALSE

&& config_item('rewrite_short_tags') === TRUE && function_usable('eval')

)

{

}

else

{

}

* Flush the buffer... or buff the flusher?

* we are beyond the first level of output buffering so that

* it can be seen and included properly by the first included

* template and any subsequent ones. Oy!
