在PHP中循环表单值，然后将它们放入数据库

如何遍历$ _POST值。

$ _ POST [ “speaker_full_name”]
$ _ POST [ “speaker_description”]

让我试着解释......

我正在尝试将字段值存储到我的数据库表中。我的代码适用于上传文件 $ _ FILES ['uploads'] ['name'] ，但字段“ speaker_full_name ”和“ speaker_description “刚刚从最后一个被取代。

希望这不会让任何人感到困惑。我尽力解释这个问题。我花了很多时间试图解决这个问题，但我需要帮助。我只是在学习php。

这是我的HTML代码

<?php
session_start();
include_once 'db-connect.php';

if (!isset($_SESSION['userSession'])) {
 header("Location: index.php");
}

$query = $DBcon->query("SELECT * FROM users WHERE user_id=".$_SESSION['userSession']);
$userRow=$query->fetch_array();
$DBcon->close();

?>

假设有问题的字段（即speaker_full_name和speaker_description〜ie：<input name='speaker_full_name[]' />）以相同的形式重复，那么可能使用相同的变量$ i来访问类似的值这可能有用吗？但是你很容易受到sql注入 - 使用准备好的语句！

// Getting the total number of files
$count = count( $_FILES['uploads']['name'] );

if( !$count ) {
    echo "Upload files.";
} else {


    // Processing each file iteratively
    for( $i = 0; $i < $count; $i++ ) {
        $file_name = $_FILES['uploads']['name'][$i];
        $ext = strtolower( pathinfo( $file_name, PATHINFO_EXTENSION ) );

        // Uploading the file

        $tmp = $_FILES['uploads']['tmp_name'][$i];
        $target_dir = "uploads/";
        $target_file = $target_dir . basename( $file_name );


        if ( move_uploaded_file( $tmp, $target_file ) ) {
            echo '
            <br />
            <strong>'.$target_file.'</strong>
            <br />';

            $sql = "INSERT INTO uploaded_files (code, users_email, speaker_full_name, speaker_description, file)
