Question

美好的一天！我是PHP的新手，想寻求帮助。

我有一个用于从数据库自动生成问题的代码以及5个复选框。我的问题是，如何从复选框中保存其他值？

任何想法将不胜感激！

<?php

        $sql = "SELECT * FROM question_pool_registrar WHERE criteria_id = 1";
        $result = $connect->query($sql);

        if($result->num_rows > 0){

            while($row = $result->fetch_assoc()){
            $question = $row['question'];
                echo "<tr>
                <td>$question</td>
                <td><input type='checkbox' value='1C-Q1-5' name='answer1' class='radio'></td>
                <td><input type='checkbox' value='1C-Q1-4' name='answer1' class='radio'></td>
                <td><input type='checkbox' value='1C-Q1-3' name='answer1' class='radio'></td>
                <td><input type='checkbox' value='1C-Q1-2' name='answer1' class='radio'></td>
                <td><input type='checkbox' value='1C-Q1-1' name='answer1' class='radio'></td>
                      </tr>";
            }
        }

        ?>

复选框的行为是，它们的输入标签要求具有相同的名称，但它们将被视为数组，因此您需要添加** [] **他们的名字大括号

<input type='checkbox' value='1C-Q1-5' name='answer1[]' class='radio'>

现在，取决于您将使用GET还是POST方法：

$_POST['answer1'] //this is an array

$answers = $_POST['answer1'] 
// we pass the fetched data first
// then we transform then into a string if you want to save them in your database

$final_answers = implode("," , $answers);

//the $final_answers variable is a STRING that now holds all the chosen checkboxes but are separated by a comma
//for example, it will hold a value "1C-Q1-5, 1C-Q1-2, 1C-Q1-1", if the user has checked the 1st, 2nd and 5th checkboxes
