Codeigniter 生成静态页面

使用CI来生成静态页面,其实很简单,就像论坛里面说的那样,读出页面中的数据,再写入html文件中,最后显示这个html文件就行了,好吧,上码。

[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;//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);

}

......

}

}

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);

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