模板复写 modulename_canvas.html ( xoops themes )

不同模块选择不同的主题风格，在themes/modules/mod name 下创建canvas的模板,themes会自动筛选模块下的canvas如果不存在，在去找自身的canvas文件．

<{php}>
// Get language files
require_once(XOOPS_ROOT_PATH.'/language/'.$GLOBALS['xoopsConfig']['language'].'/user.php');


//If a module defines its own canvas template (located themes/theme/modules/dirname/canvas.html), take it; otherwise the default canvas (themes/theme/canvas.html) is used.
if(file_exists(XOOPS_ROOT_PATH."/themes/".$this->_tpl_vars["xoops_theme"]."/modules/".$this->_tpl_vars["xoops_dirname"]."/canvas.html")) {
    $this->assign("canvas_template", $this->_tpl_vars["xoops_theme"]."/modules/".$this->_tpl_vars["xoops_dirname"]."/canvas.html");
}else{
    $this->assign("canvas_template", $this->_tpl_vars["xoops_theme"]."/canvas.html");
}

//Defined an extra SMARTY variable $xoops_themeurl, which is identical to $xoops_imageurl, for literal consistence only.
$this->assign("xoops_themeurl", $this->_tpl_vars["xoops_url"]."/themes/".$this->_tpl_vars["xoops_theme"]);

//Defined an extra SMARTY variable $xoops_module_theme.
$this->assign("xoops_module_theme", $this->_tpl_vars["xoops_theme"]."/modules/".$this->_tpl_vars["xoops_dirname"]);

//If a module has its own css (located themes/theme/modules/dirname/style.css), append it to $xoops_module_header.
if(file_exists(XOOPS_ROOT_PATH."/themes/".$this->_tpl_vars["xoops_theme"]."/modules/".$this->_tpl_vars["xoops_dirname"]."/style.css")) {
    $this->assign("xoops_module_header",
