具有一个名称的多个复选框(无jquery！) [英] Multiple checkboxes with one name (no jquery!)

问题描述

我有以下复选框列表:

<input type="checkbox" name="day_of_week" value="1">Monday
<input type="checkbox" name="day_of_week" value="2">Tuesday
<input type="checkbox" name="day_of_week" value="3">Wednessday
<input type="checkbox" name="day_of_week" value="4">Thursday
<input type="checkbox" name="day_of_week" value="5">Friday
<input type="checkbox" name="day_of_week" value="6">Saturday
<input type="checkbox" name="day_of_week" value="7">Sunday

用户提交完整表格后，我会在另一个文件中收到它:

After user submits the full form, I receive it in another file:

$week_days = mysqli_real_escape_string($this->db->conn_id, $_POST['day_of_week'])

但是$ week_days仅包含最后一个选中复选框的值，而不是全部.如何接收所有值?

But then $week_days only contains the value of the last checked checkbox, not all of them. How can I receive all the values?

推荐答案

名称应为数组.

<input type="checkbox" name="day_of_week[]" value="1">Monday
<input type="checkbox" name="day_of_week[]" value="2">Tuesday
<input type="checkbox" name="day_of_week[]" value="3">Wednessday
<input type="checkbox" name="day_of_week[]" value="4">Thursday
<input type="checkbox" name="day_of_week[]" value="5">Friday
<input type="checkbox" name="day_of_week[]" value="6">Saturday
<input type="checkbox" name="day_of_week[]" value="7">Sunday

希望这会有所帮助.

对于第二个错误，mysqli_real_escape_string接受第二个参数作为字符串，并且您正在传递数组.请检查此

For your second error, mysqli_real_escape_string accepts second parameter as string and you are passing array. Please check this

string mysqli_real_escape_string ( mysqli $link , string $escapestr )

请使用for循环解决该错误.

Please use for loop to solve that error.
