提交的时候， 怎么判断 输入的 $sqldb[link]  是否有http://
如果有则正常提交，
如果没有则 自动 添加http:// 提交


回复讨论(解决方案)

擦，截取前7个字符，再判断下是不是http://不就OK了 PHP资料

能帮忙写个例子么，急用， 有空再慢慢看。 

$str=stristr($_POST['link'],'http://') ? $_POST['link'] : 'http://'.$_POST['link'];
Copy after login

PHP code?1$str=stristr($_POST['link'],'http://') ? $_POST['link'] : 'http://'.$_POST['link'];

或者用正则表达式也行。
