Question

我对PHP和编程比较陌生，所以请原谅我的无知和语言。

我有一个包含相同输入字段的多个实例的表单（见下文）。我有一个脚本将处理输入数据，但只有在一次提交一组（也在下面）。我希望在表单的按钮上有一个提交按钮，该按钮将执行脚本，无论我在页面上有多少倍的数据集。

有没有人知道如何才能让它发挥作用？我无法重命名变量（我试过），因为接收服务器需要数据标签完全如下所示。任何帮助/方向将不胜感激。谢谢！

我的表单：

<form method="post" action="<?php echo (AUTHORIZENET_SANDBOX ? AuthorizeNetDPM::SANDBOX_URL : AuthorizeNetDPM::LIVE_URL)?>" id="checkout_form">
    <?php
    $time = time();
    $fp_sequence = $time;
    $fp = AuthorizeNetDPM::getFingerprint(AUTHORIZENET_API_LOGIN_ID, AUTHORIZENET_TRANSACTION_KEY, $amount, $fp_sequence, $time);
    $sim = new AuthorizeNetSIM_Form(
        array(
        'x_amount'        => $amount,
        'x_fp_sequence'   => $fp_sequence,
        'x_fp_hash'       => $fp,

Answer 1

PHP支持表单字段的数组表示法，因此您可以强制值多次显示。 e.g。

<input type="text" name="data[1]" value="foo" />
<input type="text" name="data[a]" value="bar" />
<input type="text" name="data[abcef]" value="baz" />

会给你一个$ _POST结构，如：

$_POST['data'] = array(
    0 => 'foo'
    'a' => 'bar'
    'abcef' => 'baz'
)

由于你有多个字段的多个副本，都要求将数据保存在一起，然后构建你的表单，如：

Set #1
<input name="somefield[1]" />
<input name="otherfield[1]" />
...

Set #2
<input name="somefield[2]" />
<input name="otherfield[2]" />

然后在提交时在服务器上执行此操作：

foreach(array_keys($somefield) as $key) {
   $somefield = $_POST['somefield'][$key];
   $otherfield = $_POSt['otherfield'][$key]; 

   ... do something ...
}

Answer 2

您可以在数组中添加表单输入，并在运行代码时使用foreach。

<input type="text" class="text required" size="4" name="cards[0][amount]" value=""></input>
<input type="text" class="text required creditcard" size="15" name="cards[0][x_card_num]" value="6011000000000012"></input>

<input type="text" class="text required" size="4" name="cards[1][amount]" value=""></input>
<input type="text" class="text required creditcard" size="15" name="cards[1][x_card_num]" value="6011000000000012"></input>

等等等。

您可以通过

获得结果

foreach($_POST['cards'] AS $c) {
    echo $c['amount'];
}

对一个表单多次使用相同的脚本（使用PHP）
