我正在开发一个由html表单组成的php项目,该表单允许用户提交文本,歌曲名称,作曲家和艺术家。用户填写表单并单击"提交"后,应存储数据并允许再次填写表单,直到用户按下另一个按钮,该按钮显示已提交的所有数据。到目前为止,我已经考虑使用数组,但我不确定这将如何与发送到同一数组的多个表单提交一起工作。任何帮助将不胜感激。
<html>
<head>

<body>
<form method="post">
Name of song: <input type="text" name="songName"><br>
Composer: <input type="text" name="composer"><br>
Artist/Group: <input type="text" name="artist"><br>
<input type="submit" name="submit">
</form>
</body>
<?php
if (!empty($_POST['submit'])) {
//Submit the data into the array or something here
}
?>
</html>
当然,试试这个,看看会发生什么:
<?php
session_start();
// Initialize an array for answers
if (!isset($_SESSION['answers']))
$_SESSION['answers'] = array();
?>

<body>
<form method="post">
Name of song: <input type="text" name="songName"><br>
Composer: <input type="text" name="composer"><br>
Artist/Group: <input type="text" name="artist"><br>
<input type="submit" name="submit">
</form>
</body>
<?php
if (!empty($_POST['submit'])) {
// Push the posted data into the session array
$_SESSION['answers'][] = $_POST;
}
// Display the data now
foreach($_SESSION['answers'] as $array) {
echo "Name of song: {$array['songName']}<br>";
echo "Composer: {$array['compose']}<br>";
echo "Artist/Group: {$array['artist']}<br><hr>";
}
?>
