上面一个是PHP写入数据库的处理文件
一个是表单提交文件，我想要的是，比如，pc的值提交为“ff”，提交后，PHP文件成功写入数据库后，如何自动跳转"ff"值链接

			elseif($pc=="ff"){				$url="www.baidu.com";				Header("Location:$url"); 				exit;			}

就是如何成功写入数据库后，自动跳转这个链接

回复讨论(解决方案)

29行：$pc = intval(R('pc', 'P'));
都intval了，不管是hh ff 还是dd，最后$pc都为0了，所以跳不过去
另外跳转需要绝对路径：http://开头

这个问题，我改了，但是也跳转不过去，成功写入数据库后，页面一片空白

(int)$habits['last_add_cid'] : 0;			$data = $this->kv->get('auto_save_record_uid_'.$uid);			if($data) {				!empty($data['cid']) && $cid = $data['cid'];			}else{				$data['intro'] = array();				$data['views'] = 0;			}			$this->assign('data', $data);			$cidhtml = $this->category->get_cidhtml_by_mid(2, $cid);			$this->assign('cidhtml', $cidhtml);			$edit_cid_id = '&mid=2';			$this->assign('edit_cid_id', $edit_cid_id);			$this->display('record_set.htm');		}else{			$cid = intval(R('cid', 'P'));			$products = intval(R('products', 'P'));			$amount = intval(R('amount', 'P'));			$pc = intval(R('pc', 'P'));			$data = array(				'cid' => $cid,				'products' => $products,				'amount' => $amount,				'ip' => ip2long($_ENV['_ip']),			);			$this->cms_content->table = 'cms_record';			$id = $this->cms_content->create($data);			if(!$id) {				E(1, '写入内容表出错');			}			$this->_user['contents']++;			$this->user->update($this->_user);			$categorys['count']++;			$this->category->update($categorys);			$this->category->update_cache($cid);			$data = $this->kv->delete('auto_save_record_uid_'.$uid);			$habits = (array) $this->kv->get('user_habits_uid_'.$uid);			$habits['last_add_cid'] = $cid;			$habits = $this->kv->set('user_habits_uid_'.$uid, $habits);			//E(0, '发布完成'.$endstr);			if(!$data->E(0,$endstr)){				exit;			}			elseif($pc=="1"){				$url="http://www.w3school.com.cn";				Header("Location:$url"); 				exit;			}			elseif($pc=="2"){				$url="www.baidu.com";				Header("Location:$url"); 				exit;			}			elseif($pc=="3"){				$url="bbs.csdn.net";				Header("Location:$url"); 				exit;			}			    else{				$url="http://www.baidu.com";				Header("Location:$url");				exit;			}		}	}}
