这是流应该如何工作，我检查几个记录，复选框应该通过用户的ID到编辑页面，它应该显示被检查的记录。使用print_r（$ _ POST）显示了被传递到数组的id如下（Array（[checkbox2] => Array（[0] => 378 [1] => 379）））。但是它显示了用户的每个记录。

This is how the flow should work, I check several records, the checkbox should pass the id of the user to the edit page where it should display the records that are checked. Using print_r($_POST) there shows the id being passed into the array like so (Array ( [checkbox2] => Array ( [0] => 378 [1] => 379 ) ) ) . However it displayed out every record of the users.

推荐答案

对于通过多个复选框值，使用输入名称作为数组。

For pass multiple checkbox value use input name as array.

<input type="checkbox" name="checkbox[]" />
