为什么要将转义字符添加到隐藏输入的值中 [英] Why are escape characters being added to the value of the hidden input
问题描述
<身体GT;
< div> <？= $ _POST ['msg']？> < / DIV>
< form id =frmmethod =post>
< input type =hiddenname ='msg'value ='{field0：Im a string，field1：84，field3：so I I}'/> ;
< input type =submitvalue =test/>
< / form>
< / body>
发布表单时，div标签之间会显示以下字符串。
{\field0 \：\Im a string \，
\field1 \：84， \field3 \：\so
I \}
为什么转义字符被添加？
它们是由PHP服务器还是Web客户端添加的？
我可以做任何事情来预防这种情况吗？
有人已经提到了PHP函数stripslashes。我现在使用它，但我想摆脱所有斜线。 解决方案
检查您的PHP配置是否有 magic_quotes_gpc 激活，在这种情况下，PHP服务器会自动为GET / POST / cookie值添加斜杠...
<body>
<div> <?= $_POST['msg'] ?> </div>
<form id="frm" method="post">
<input type="hidden" name='msg' value='{"field0": "Im a string", "field1": 84, "field3": "so am I"}' />
<input type="submit" value="test" />
</form>
</body>
When the form is posted, the following string is displayed between the div tags.
{\"field0\": \"Im a string\", \"field1\": 84, \"field3\": \"so am I\"}
Why are the escape characters being added? Are they being added by the PHP server or the web client? Can I do anything to prevent this?
Someone already mentioned the PHP function stripslashes. I'm using it for now but I want to get rid of the slashes all together.
Check whether your PHP configuration has magic_quotes_gpc activated, in such case the PHP server automatically adds slashes to GET/POST/cookie values...
