blocks|key|276416|text|不是的。只要每个字段都有一个惟一的名称，就可以使用任意数量的名称：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|276417|<input+type="hidden"+name="must-be-unique"+value="Some+value"/>|code-block|syntax|javascript|276418|编辑：唯一名称规则有一个例外。在单选按钮或任何希望将数据作为数组传递的情况下，您可以为多个输入使用相同的名称。|offset|length|style|BOLD|276419|entityMap^0|0|0|0|3|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

No. As long as each field has a unique name you are fine using as many as you would like:

<pre><code>&lt;input type="hidden" name="must-be-unique" value="Some value"/&gt;
</code></pre>

EDIT: There is an exception to the unique name rule. In the case of radio buttons or anything where you'd like the data to be passed as an array, you may use the same name for multiple inputs.

blocks|key|276441|text|在一个表单中有多少隐藏字段是“没有”限制的..！|type|unstyled|depth|inlineStyleRanges|entityRanges|data|276442|但是，当您试图发布所有隐藏字段和普通字段的值时，不应该超过在size中定义的php.ini值。|offset|length|276443|entityMap|0|LINK|mutability|MUTABLE|url|http://www.php.net/manual/en/function.ini-get.php^0|0|U|4|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

There is "NO" limit over how many hidden fields are there in a form..!

But, when you are trying to POST the value of all the hidden fields and normal should not more than <a href="http://www.php.net/manual/en/function.ini-get.php">post_max_size</a> which is defined in php.ini

blocks|key|276463|text|有些浏览器(例如:+Netscape、IE)对隐藏字段内容大小有限制，但对字段计数没有限制。在这种情况下，快速漫游是将内容划分为多个隐藏字段。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|276464|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Some browsers (ex: Netscape, IE) have a limit for hidden field content size, but not for field count. In those situations the quick walkaround is to divide content into multiple hidden fields.

blocks|key|276495|text|实际上，有一些PHP参数控制/影响输入$_POST和$_GET数据的处理。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|276496|这些是|276497|max_input_vars+=+??+++//+default+is+1000,+the+number+of+fields+php+will+process
max_input_time+=+??+++//+maximum+time+in+seconds+a+script+is+allowed+to+parse+input+data,+like+POST+and+GET
post_max_size+=+??++++//+Sets+max+size+of+post+data+allowed.|code-block|syntax|javascript|276498|这些不是与“隐藏”字段具体相关的，而是与字段总数或缓冲区大小有关。如果隐藏字段是窗体上定义的最后一个字段，且字段数或后置缓冲区的大小为大，则php在达到限制时就停止处理。但是，您至少应该在php+error+log中看到这样的警告，这样的事情已经发生了。|offset|length|style|CODE|276499|entityMap^0|0|0|0|2M|D|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|R|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|S|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|T|8|@$K|U|L|V|M|N]]|9|@]|A|$]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

Actually there are some PHP parameters that control/effect the processing of inputs $_POST and $_GET data.

These are

<pre><code>max_input_vars = ?? // default is 1000, the number of fields php will process
max_input_time = ?? // maximum time in seconds a script is allowed to parse input data, like POST and GET
post_max_size = ?? // Sets max size of post data allowed.
</code></pre>

These are not specifically related to "hidden" fields but to the total number of fields or size of the buffer. If your hidden fields are the last fields defined on your form and the number of fields or size of POST buffer is to large, php just stops processing when the limit it reached. However you should see at least a warning in your <code>php error log</code> to say something like this has happened.

blocks|key|139024|text|如果您使用JS动态生成隐藏字段(例如，可以限制)，否则您无法控制并且有许多字段可能会使您的页面性能变差--您可以使用JS定期检查以计数隐藏字段，并且可以根据您的实现删除最后添加的字段，还可以在HTML中使用同名的N个元素，但在PHP中我不知道您是否会面临限制|type|unstyled|depth|inlineStyleRanges|entityRanges|data|139025|function+checkDOMChange()
{
++++//+check+for+any+new+element+being+inserted+here,
++++//+or+a+particular+node+being+modified

++++//+call+the+function+again+after+100+milliseconds
++++setTimeout(+checkDOMChange,+100+);
}|code-block|syntax|javascript|139026|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

In case you are generating hidden fields dynamically using JS for example you can limit, else you cannot control and having many fields may make your page performance bad
You can make periodical check using JS to count hidden fields and you may delete last added ones based on your implementation
Also you can have N elements with same name in HTML but in PHP I don't know if you will face limitation or not

<pre><code>function checkDOMChange()
{
 // check for any new element being inserted here,
 // or a particular node being modified

 // call the function again after 100 milliseconds
 setTimeout( checkDOMChange, 100 );
}
</code></pre>

<code>&lt;input type="hidden" value="Is there any limit that how many Hidden Fields ? "/&gt;</code>

Is there any limit for the how many Hidden Fields can be used in the HTML Form?
If Yes, can you please elaborate the reason..?

Thanks..!
