PHP表单POST中的复选框是否有限制？ [英] Is there a limit on checked checkboxes in PHP form POST?

问题描述

我遇到了一个问题，似乎无法解决。我有一个表单（method = post enctype = multipart / form-data），用户可以在其中选择一些选项。他们
可以全部检查。如果他们全部选中，则表示他们正在检查
2000多个框。要检查我的表单是否实际发布，我有以下（不太复杂）代码：

I've come across a problem, which I can't seem to fix. I have a form (method="post" enctype="multipart/form-data") in which the user can choose some options. They have the possibility to 'check all'. If they 'check all', they are checking about 2000+ boxes. To check if my form actually gets posted, I have the following (not so complex) code:

<?php

if(isset($_POST['bijwerken'])) {

echo "YIPPEE!!";

}

?>

现在，如果我选中所有复选框，则不会得到任何反馈。如果我只选择20个框，我实际上会得到反馈。我想念什么？复选框也由脚本生成，并带有回显：

Now, if I check all the boxes, I don't get any feedback. If I only select like 20 boxes, I do actually get feedback. What am I missing? The checkboxes are also generated by a script, with an echo :

echo "&nbsp;&nbsp;<input type=\"checkbox\" name=\"productsoorten[]\" value='" . $rowproductsoorten1[productsoort1] . "'>&nbsp;  " . $rowproductsoorten1[productsoort1] . "<br />"; 

希望听到一些好主意！

推荐答案

是的，实际上是 max_input_vars 设置。默认值为1000，如果输入字段的数量超过该数量，则您的帖子输入将不起作用。

Yes, there's actually a max_input_vars setting. The default value is 1000 and your post inputs won't work if the number of input fields are more than that.

编辑您的 php.ini 文件（如果在Unix系统上，通常位于 /etc/php5/apache2/php.ini ）并增加限制：

Edit your php.ini file (usually at /etc/php5/apache2/php.ini if you're on a Unix system) and increase the limit:

max_input_vars = 5000

如果无法修改 php.ini 文件，则可以将其添加到 .htaccess ：

If you can't modify the php.ini file, you can add this to .htaccess:

php_value max_input_vars 5000
