ThinkPHP中重定向(redirect方法)
redirect 重定向的通用语法为:redirect(url,params=array(),delay=0,msg=)
用法:
protected function redirect($url,$params=array(),$delay=0,$msg=){
$url = U($url,$params);
redirect($url,$delay,$msg);
}
源码:参见框架内置的functions.php文件
function redirect($url,$time=0,$msg=){
//多行URL地址支持
$url=str_replace(array("
","
"),,$url);
if(empty($msg)) $msg="系统将在{$time}秒之后自动跳转到{$url}！";
if(!headers_sent()){
//redirect
if($time == 0){
header(Location:.$url);
}else{
header("refresh:{$time};url={$url}");
echo($msg);
}
exit();
}else{
$str="<metahttp-equiv=Refreshcontent={$time};URL={$url}>";
if($time != 0) $str.=$msg;
exit($str);
}
}
// URL重定向
function redirect($url,$time=0,$msg=){
//多行URL地址支持
$url=str_replace(array("
","
"),,$url);
if(empty($msg)) $msg="系统将在{$time}秒之后自动跳转到{$url}！";
if(!headers_sent()){ //如果标头没有发出
//redirect
if($time == 0){
header(Location:.$url);//如果没有指定延时时间，则发一个跳转标头
}else{
header("refresh:{$time};url={$url}");//如果制定了延时时间，则发一个延时刷新的标头
echo($msg);
}
exit();
}else{ //否则就发送meta标记，含义同上
$str="<metahttp-equiv=Refreshcontent={$time};URL={$url}>";
if($time != 0) $str.=$msg;
exit($str);
}
}
function redirect($url,$time=0,$msg=){
//多行URL地址支持
$url=str_replace(array("
","
"),,$url);
if(empty($msg)) $msg="系统将在{$time}秒之后自动跳转到{$url}！";
if(!headers_sent()){
//redirect
if($time == 0){
header(Location:.$url);
}else{
header("refresh:{$time};url={$url}");
echo($msg);
}
exit();
}else{
$str="<metahttp-equiv=Refreshcontent={$time};URL={$url}>";
if($time != 0) $str.=$msg;
exit($str);
}
}
