Question

通常不知道如何＆＃34;插入＆＃34;复选框进入数据库，我有一个带有几个复选框的表单...大约25个复选框，每个复选框具有相同的名称和1-25的值，现在我需要它们具有相同的名称，以便运行一个脚本，防止选择不超过4个复选框...

HTML代码

<input type="checkbox" name="ckb" id="EngineeringWorkshops" value=1 onclick='chkcontrol(0)';>
<label for="EngineeringWorkshop"> Engineering Workshops           </label>

PHP代码

$engineeringworkshops = mysqli_real_escape_string($dbcon, $_POST['cob']); 


    $sql="INSERT INTO courses (studentid, engworkshops)
    VALUES ('$studentid', '$engineeringwokshops')";

engworkshops列类型是tinyint（4）默认值设置为0

Answer 1

使用这样的html：

<form>
<input type='checkbox' name='data[]' value='YourId' /> Data
<input type='checkbox' name='data[]' value='AnotherId' /> AnotherData
<input type='checkbox' name='data[]' value='OneMoreId' /> OneMoreData
// others
</form>

如何在php中处理这些数据？

使用此：

$engineeringworkshops = mysqli_real_escape_string($dbcon, $_POST['cob']); 
// handle data from checkboxes
foreach($_POST['data') as $item) {
    // do something in item
    $sql="INSERT INTO courses (studentid, engworkshops) VALUES ('$item', '$engineeringwokshops')";
}
