【问题描述】：
我正在尝试通过 HTML 表单和隐藏字段向 php 中的数组添加值。首先，我从我的 php 文件中的帖子中获取值，然后像 index.php 一样将值添加到数组中：
<?php
$gamelist = filter_input(INPUT_POST, 'gamelist',FILTER_DEFAULT, FILTER_REQUIRE_ARRAY);
$key = filter_input(INPUT_POST, 'gameID', FILTER_VALIDATE_INT);
$team1 = filter_input(INPUT_POST, 'teamID1', FILTER_VALIDATE_INT);
$team2 = filter_input(INPUT_POST, 'teamID2', FILTER_VALIDATE_INT);
$date = filter_input(INPUT_POST, 'date');
if ($gamelist === NULL) {
$gamelist = array();
}
if ($new_game === NULL) {
$new_game = array();
}
//get action variable from POST
$action = filter_input(INPUT_POST, 'action');
//initialize error messages array
$errors = array();
//process
switch( $action ) {
case 'Add Game':
$new_game[] = $date;
$new_game[] = $team1;
$new_game[] = $team2;
$gamelist[] = $new_game;
break;
case 'Delete Game':
$game_index = filter_input(INPUT_POST, 'gameID', FILTER_VALIDATE_INT);
if ($game_index === NULL || $game_index === FALSE) {
$errors[] = 'The game cannot be deleted.';
} else {
unset($gamelist[$game_index]);
$gamelist = array_values($gamelist);
}
break;
}
include('gamelist.php');
?>
此代码的输出如下所示。这正是我想要的。
Array
(
[0] => Array
(
[0] => 2/30/15
[1] => 1
[2] => 2
)
)
但是，当另一个游戏被添加时（当另一个数组被添加到 $gamelist[] 时）该数组会忘记之前的数组并变成这样：
Array
(
[0] => Array
[1] => Array
(
[0] => 5/17/2015
[1] => 2
[2] => 3
)
)
我需要 [0] 数组来保留我之前传递给它的值。
有什么想法？？？
下面是带有隐藏字段的完整 html 端 (gamelist.php)：
<?php
require('../database.php');
$query = 'SELECT * FROM team_table';
$statement = $db->prepare($query);
$statement->execute();
$teams = $statement->fetchAll();
$team = $statement->fetch();
$statement->closeCursor();
?>
<!DOCTYPE html>
<html>
<head>
<title>RP LL Game List</title>
<link rel="stylesheet" type="text/css" href="main.css" />
</head>
<body>
<header>
<h1>RP LL Game List</h1>
</header>
<main>
<!-- Dumping gamelist and errors arrays -->
<h2>Errors:</h2>
<?php if (count($errors) == 0) : ?>
<p>There are no errors</p>

<?php endforeach; ?></ul>
<?php endif; ?>
<h2>Games:</h2>
<?php if (count($gamelist) == 0) : ?>
<p>There are no games in the game list.</p>
<?php else: ?>

<?php print_r($gamelist); ?>

【问题讨论】：
-
发布您的完整代码。你的数组不可能有这个代码的两个值。您必须在其他地方初始化/存储 $gamelist，这可能就是问题所在。
