ThinkPHP入库出现两次反斜线转义及数据库类转义的解决方法,thinkphp斜线
本文实例讲述了ThinkPHP入库出现两次反斜线转义及数据库类转义的解决方法。分享给大家供大家参考。具体方法如下:
这种情况是在 magic_quotes_gpc 开启的情况下发生的。原因是thinkphp在入库的时候没有判断 magic_quotes_gpc 是否开启,不管三七二十一地进行了转义处理。
解决办法是在入口文件增加如下代码则可:
复制代码 代码如下:
if (!get_magic_quotes_gpc()) {
function addslashes_deep($value) {
$value = is_array($value) ?
array_map('addslashes_deep', $value) :
addslashes($value);
return $value;
}
$_POST = array_map('addslashes_deep', $_POST);
$_GET = array_map('addslashes_deep', $_GET);
$_COOKIE = array_map('addslashes_deep', $_COOKIE);
$_REQUEST = array_map('addslashes_deep', $_REQUEST);
}
有人这样修改DbMysql.class.php中的转义函数:
复制代码 代码如下:
public function escape_string($str) {
if (get_magic_quotes_gpc()) {
return $str;
}
if($this->_linkID) {
return mysql_real_escape_string($str,$this->_linkID);
}else{
return mysql_escape_string($str);
}
}
其实这种方法并不可取!因为如果魔术函数on时,而$str又不是post或get得来(比如读取文本、数据库),它还是没加反斜线。
所以我不管$str是否已经被转义,一律先去除转义,然后再加上转义。这样就避免了二次转义,也避免了遗漏转义。
下面是我的修改方法:
复制代码 代码如下:
public function escape_string($str) {
$str = stripslashes($str);
if($this->_linkID) {
return mysql_real_escape_string($str,$this->_linkID);
}else{
return mysql_escape_string($str);
}
}
希望本文所述对大家的ThinkPHP框架程序设计有所帮助。
和数据库没关系,和php插入语句有关,查询一下插入语句 肯定有些是转意的有些没有
不escape你都insert into不进去吧,会报错的
不过单引号还比较恶心,加的时候需要多加一个单引号转意
