模板不能动态包含
像这样<!--{template template/default/course/$space[school]}-->
因为执行解析模板时,先解析
$template = preg_replace("/\<\!\-\-\{template\s+([a-z0-9_\/]+)\}\-\-\>/ie", "readtemplate('\\1')", $template);
表达式中不允许存在$符号
function parse_template($tpl) {
global $_SGLOBAL, $_SC, $_SCONFIG;
//包含模板
$_SGLOBAL['sub_tpls'] = array($tpl);
$tplfile = S_ROOT.'./'.$tpl.'.htm';
$objfile = S_ROOT.'./data/tpl_cache/'.str_replace('/','_',$tpl).'.php';
//read
if(!file_exists($tplfile)) {
$tplfile = str_replace('/'.$_SCONFIG['template'].'/', '/default/', $tplfile);
}
$template = sreadfile($tplfile);
if(empty($template)) {
exit("Template file : $tplfile Not found or have no access!");
}
