您好我想获取所有$row['student_id']复选框值并在数据库中插入其ID $row['student_id'及其值（0或1）

<tr>
  <td>1</td>
  <td>Student Name</td>
  <td><div class="checkbox">
        <label>
          <input type="checkbox" name ="check_list[]" class="control-info" value="1">
        </label>
      </div></td>

      </div></td>
</tr>

下次请尝试展示您的工作努力。我花时间研究这个剧本，因为我看到你像我一样在这里。所以我欢迎来到伟大的stackoverflow.com。此代码将按要求运行。

首先创建两个我在脚本中注释的表，然后插入值。更改数据库凭据并运行脚本，你很高兴

<?php
error_reporting(0);

/*
CREATE TABLE `student` (
`id` int(4) primary key auto_increment,
`firstname` varchar(65) NOT NULL default '',
`lastname` varchar(65) NOT NULL default '',
`student_id` varchar(65) NOT NULL default '');



CREATE TABLE `new_student` (
`id` int(4) primary key auto_increment,
`firstname` varchar(65) NOT NULL default '',
`lastname` varchar(65) NOT NULL default '',
`student_id` varchar(65) NOT NULL default '');



INSERT INTO `student` VALUES (1, 'Billly', 'Blueton', '100');
INSERT INTO `student` VALUES (2, 'Jame', 'Campbell', '200');
INSERT INTO `student` VALUES (3, 'Mark', 'Jackson', '300');
INSERT INTO `student` VALUES (4, 'Billly', 'Blueton', '400');

INSERT INTO `student` VALUES (5, 'Jame', 'Campbell', '500');

INSERT INTO `student` VALUES (6, 'Mark', 'Jackson', '600');
*/



// use PDO
$db = new PDO (
    'mysql:host=localhost;dbname=student_db;charset=utf8', 
    'root', // username

    '' // password
); 


$sql = $db->prepare('SELECT * FROM student');
$sql->execute(array());
//$result = $sql->fetch();
$count = $sql->rowCount();

?>

<?php

// Check if delete button active, start this 
$add =$_POST['add'];
$checkbox =$_POST['checkbox'];
//$delete;
if($add){
for($i=0;$i<$count;$i++){
$student_id = $checkbox[$i];






$statement = $db->prepare('INSERT INTO new_student(student_id)values(:student_id)');

if($statement->execute(array(':student_id' => $student_id))){
echo "inserted";
}else{
echo "error";
}

}

}

?>

您可以使用以下框架来迭代每个已检查学生。

if( isset( $_POST['check_list'] ) ) {
        foreach( $_POST['check_list'] as $student_id ) {
            // Do Insert to database here, each value is at $student_id variable
        }
    }
