使用 Import 上传 CSV 文件时，仅导入 1 条记录

Question

我们的 CSV 文件中有数千条记录，我想一次性上传。当我选择 CSV 文件时，只有 1 条记录导入到 mysql 表中。请检查代码，让我知道如何解决它。

    <?php
//load the database configuration file
include 'csv_css.css';
include 'dbConfig.php';

if(!empty($_GET['status'])){
switch($_GET['status']){
    case 'succ':
        $statusMsgClass = 'alert-success';
        $statusMsg = 'Members data has been inserted successfully.';
        break;
    case 'err':
        $statusMsgClass = 'alert-danger';
        $statusMsg = 'Some problem occurred, please try again.';
        break;
    case 'invalid_file':
        $statusMsgClass = 'alert-danger';
        $statusMsg = 'Please upload a valid CSV file.'; 
        break;
    default:
        $statusMsgClass = '';
        $statusMsg = '';
}
}
?>
<div class="container">
<?php if(!empty($statusMsg)){
    echo '<div class="alert '.$statusMsgClass.'">'.$statusMsg.'</div>';

这通常是因为您没有在 ID 列上设置“自动增量”，请确保您为 MySQL 表上的 ID 列启用了自动增量，并且脚本应该按预期工作。
