php - 如何在数据库的不同行中保存多个复选框值

Question

我正在处理一个复选框表，提交的数据应该保存在mysql数据库中。表中有两列，自动增量Id，另一列用于保存复选框的值。

目前，即使我选择多个值，一次也只能保存一个值，也只会保存最新的一个值。代码如下:

report.php

<?php


$active = "report";
require_once 'pages/header.php';
require_once './functions/schema-functions.php';

$course = Schema::getCourse();
$objective = Schema::getObjective();
?>




<form id="addReport" action ='./functions/report-functions.php' method="post">

<table id="table1" class="table">
    <?php
    echo '<tr><th>Objectives</th>';
    for ($i = 0; $i < count($course); $i++) {
        echo '<th id = "rotate1">'. $course[$i]->commonName . '</th>';            
    }
    echo '</tr>';

    for ($y = 0; $y < count($objective); $y++) {
        echo '<tr><th class=row-header>'.$objective[$y]->objective.'</th>';

    for ($x = 0; $x < count($course); $x++) {

        echo "<td><input name='check[]' type=checkbox value=c".$course[$x]->courseId."-o".$objective[$y]->objectiveId." id=checked></td>";

        }
        echo '</tr>';
    }
    ?>

</table>
<input type="submit" name= "submit" value= "Submit"/>

报告函数.php

<?php


 require_once 'db-connect.php';

if(isset($_POST['submit'])){
{


$conn = DatabaseConnection::getConnection();
    $conn->beginTransaction();
    if(isset($_POST['check'])){
   foreach($_POST['check'] as $value){
    $sql = $conn->prepare("INSERT INTO Report (ColRow) VALUES 
 ('$value')");
  }
    if ($sql->execute(array( ':checked' => $checked))) {
        $conn->commit();
        return true;
    } else {
        $conn->rollback();
        return false;
    }

   }
   }
   }
    ?>

我想将多个选定的复选框保存在数据库的不同行中，提交后，我想再次显示表格并选中复选框，并且用户应该能够再次进行检查并提交数据。

要保存记录，您可以尝试这样:

<?php

    if( isset( $_POST['submit'], $_POST['check'] ) ){
        try{

            require_once 'db-connect.php';
            $conn = DatabaseConnection::getConnection();


            $sql='insert into `report`  ( `colrow` ) values ( :value )';
            $stmt = $conn->prepare( $sql );



            if( $stmt ){

                $conn->beginTransaction();

                foreach( $_POST['check'] as $index => $value ) {
                    $result = $stmt->execute( [ ':value' => $value ] );
                    if( !$result ) {
                        throw new Exception( sprintf( 'Failed to execute query %d for %s', $index, $value ) );
                    }
                }

                $conn->commit();
                exit();
            }
        }catch( Exception $e ){
            $conn->rollback();
            exit( $e->getMessage() );
        }
    }
?>
