Question

我试图将数据从表单传递到另一个文件中的另一个函数，但是这个函数已经有来自另一个函数的其他变量。

<form method="post" action="data.php">
    <input type="hidden" name="url" value="http://www.website.com/">
    <input type="hidden" name="description" value="description of website">
    <input type="hidden" name="image" value="http://www.website.com/image.jpg">
    <input type="hidden" name="board_ids" value="$board_ids">
</form>

data.php

<?php
    function login()
    {
        random variables with cURL included which is passing data to the post function

        post($ch, $cookie, $url);
    }

    function post()
    {
        uses $ch, $cookie, $url.
    }
?>

现在，在上面的函数login（）中，我有以下内容..

$post_url       = $_POST['url'];
$post_desc  = $_POST['description'];
$post_image    = $_POST['image'];
$board_ids      = $_POST['board_ids'];

PS：board_ids是一个包含一些特定ID的数组，例如：$board = array('102938', '483756', '002938', '239384');

for($i = 0; $i < count($board_ids); $i++ )
{
    post($board_ids[$i]);
}

我想知道如何将$ post_url，$ post_desc，$ post_image和$ board_ids发送到post（）函数。

我实际上想要每次使用每个board_id数组运行post（），这可能吗？以上一直说我在帖子功能上有PHP Notice: Undefined offset: 2。已经连续9个小时了，无法将变量传递给后期功能，不得不寻求帮助。

Answer 1

首先，您正在调用pinPost，但您的函数实际上名为Post。将其重命名为：

function pinPost($ch, $pinCookie, $url)

其次，您的pinPost函数正在接收三个从不使用的参数（$ch, $pinCookie, $url）。

第三，您的pinPost函数正在尝试使用从未传递给它的四个变量：

function Post($ch, $pinCookie, $url)
{
    $boardId    = $board[$i];
    $postDesc   = $post_desc;
    $postUrl    = $post_url;
    $postImage  = $post_image;

}

$board[$i]，$post_desc，$post_url和$post_image来自何处？

最后，如果您想在pinPost函数中访问这些变量，只需直接访问它们：

function pinPost()
{
    $postDesc   = $_POST['post_description'];
    $postUrl    = $_POST['post_url']';
    $postImage  = $_POST['post_image'];
    $boardId    = $_POST['post_board_id'];

}

您可能希望阅读一些PHP教程，特别是有关函数的教程。这是非常基本的东西，你真的想要理解。

对于帖子标记，您需要一个sumbit按钮或ajax提交。

例如：

<form method="post" action="data.php">
    <input type="hidden" name="url" value="http://www.website.com/">
    <input type="hidden" name="description" value="description of website">
    <input type="hidden" name="image" value="http://www.website.com/image.jpg">
    <input type="hidden" name="board_ids" value="$board_ids">
    <button type="submit">Submit</button> // submit button
</form>

或使用jquery

$("#theForm").ajaxForm({url: 'data.php', type: 'post'});

另外我建议在data.php页面上使用if（isset（variable））statment来检查变量是否存在
