PHP-форма с возможностью загрузки нескольких файлов

Question

PHP-форма с возможностью загрузки нескольких файлов

1

Я пытаюсь приспособить форму php, которую я нашел, называется "fns". Он использует до загрузки страницы

<?php
session_start();

require_once('parts-request-fns.php'); 
$_SESSION['myForm'] = $_POST;

?>

и где я хочу, чтобы форма появлялась

<?php
            // contact form
            if (isset($_POST['submitted']) && ('true' == $_POST['submitted'])) { 
                // checks if the form is submitted and then processes it
                process_form(); 

            } else { 
                // else prints the form
                print_form(); 
            }

            ?>

ссылающийся на part-request-fns.php выглядит следующим образом. Мне нужно 3 поля для загрузки файлов, поэтому мой вопрос заключается в том, как я смогу адаптировать код, чтобы можно было разместить все 3 файла? В настоящее время каждый файл может быть отправлен в форму, но публикуется только первая. Я изменил идентификатор ввода, имя на второе вложение и третье вложение, но не уверен, как ссылаться на него дальше.

    <?php
//start session
session_start();

// prints form
function print_form(){
?>

<form method="post" action="<?php echo $_SERVER[PHP_SELF];?>" id="uploadform" enctype="multipart/form-data" style="font-size: 16px;

файлы передаются в php в переменной $_FILES а не переменной $_POST. http://php.net/manual/en/reserved.variables.files.php

вы можете перемещать файлы с помощью функции move_uploaded_file().

Pankaj · Answer 2 · 2015-08-24T09-28-00.000Z

Также возможно одновременно загружать несколько файлов и автоматически создавать информацию в массивах для вас. Для этого вам нужно использовать тот же синтаксис представления массива в HTML-форме, что и с несколькими выборами и флажками:

    <form action="file-upload.php" method="post" enctype="multipart/form-data">
      Send these files:<br />
      <input name="userfile[]" type="file" /><br />
      <input name="userfile[]" type="file" /><br />
      <input type="submit" value="Send files" />
    </form>

и вы можете получить данные формы следующим образом:

$_FILES['userfile']['name'][0] , $_FILES['userfile']['name'][1]....
