<?php
foreach($pClass->retrieveAllInfo() as $data)
{ 
    echo '
    <form method="post" action"">
        <input type="hidden" name="post_url" value="'.$data['p_Url'].'">'.$data['p_Url'].'
        <input type="hidden" name="post_description" value="'.$data['p_Description'].'">'.$data['p_Description'].'
        <input type="hidden" name="post_image" value="'.$data['p_Image'].'">'.$data['p_Image'].'

        <ul class="items">';?>
        <?php 
            foreach($pClass->retrieveBoards() as $data)
            {
                echo '
                    <li><input type="checkbox" name="post_board_id[]" value="'.$data['boardiD'].'">'.$data['boardName'].'</li>
                ';
            }
        ?>
        <?php 
        echo '
        </ul>
        <input name="post_info" type="submit" value="Post">     
    </form>';
?>

在同一档案中，我有以下内容..

if(isset($_POST['post_info']))
{
    pinLogin(); //calls and runs the function

    foreach($_POST['post_board_id'] as $data)
    {
        echo '<pre>'; var_dump($data); echo '</pre>'; //just retrieving the arrays
    }
}

function pinLogin() // logs into website with headers
{
    $ch         = // ch is a variable from cURL
    $cookie     = '/cookie.txt'; //cookie session
    $url        = 'http://www.website.com/'; // website to post data to

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

function pinPost($ch, $cookie, $url) // posts the information below to the website above
{       
    $boardId    = // here needs to be the board id that needs to be runned for each array..
    $postDesc   = $_POST['post_description'];
    $postUrl    = $_POST['post_url'];
    $postImage  = $_POST['post_image'];

}

所以基本上，当你按下post_info按钮时，它会运行pinLogin()函数，该函数使用从表单发送的信息运行pinPost()，事情是{{1 }};是一个数组，$_POST['post_board_id']得到以下结果：

var_dump

我基本上需要将每个数组发布为string(18) "136234026166934321" string(18) "286119451265381250" string(18) "106468047379795203" string(18) "468022654964640361" string(18) "409757334785529893" string(18) "409757334785575605" string(18) "490681390589888313"内的$boardId，然后为所有其他数组运行pinPost()。为了让它变得非常容易理解，这正是我想要做的。

当我点击帖子按钮时，它会抓取第一个数组pinPost()，将其作为string(18) "136234026166934321"提交给pinPost()，然后它将返回到开头并运行第二个数组，$boardId直到所有数组都被提交，几乎只是将相同的信息发布到不同的板上，这正是我想要做的。

我试过做一个for循环并在里面运行string(18) "286119451265381250"但是我无法将Board ID传递给pinPost()函数，所以它不会运行。

因此，您可以使用一些不同的技术来实现这一目标。我的偏好是使用 array_walk ，因为它的回调接受数组的键和值。 array_map 也可以在这里使用，但它只能在回调中使用数组的值。

$postBoards = $_POST['post_board_id'];

function pinLogin() 
{
    $ch         = // ch is a variable from cURL
    $cookie     = '/cookie.txt'; //cookie session
    $url        = 'http://www.website.com/';

    // Run the pinPost callback for each element of $postBoards
    // with your custom user data from this function
    array_walk("pinPost", $postBoards, array($ch, $cookie, $url);
}

function pinPost($boardId, $boardKey, $data)
{
    // You have your boardId for each submitted board available here
    $postDesc   = $_POST['post_description'];
    $postUrl    = $_POST['post_url'];
    $postImage  = $_POST['post_image'];

    // $data contains your pinPost data for example
    $ch = $data[0];
}

这使得pinPost函数成为$postBoards数组的每个元素的回调函数，并且在您调用pinLogin()后将按顺序为每个数组条目运行。

您可以尝试更新代码，如下所示

  /**
   * logs into website with headers
   */
  function pinLogin() {
     $ch = // ch is a variable from cURL
     $cookie = '/cookie.txt'; //cookie session
     $url = 'http://www.website.com/'; // website to post data to


     /**
      * here iterate over all of your board id's and pass them to pin post function. The pinPost function
      * will be run 18 times
      */
     foreach($_POST['post_board_id'] as $boardId) {
        /**
         * @var $boardId string this is the 18 characters long stringg $boardid
         */
        pinPost($ch, $cookie, $url, $boardId);
     }
  }

  /**
   * posts the information below to the logged in website
   *
   * @param $ch
   * @param $cookie
   * @param $url
   * @param $boardId id of the board you want to pin post to (NEW PARAMETER)
   */
  function pinPost($ch, $cookie, $url, $boardId) {
     //$boardId is already here
     $postDesc = $_POST['post_description'];
     $postUrl = $_POST['post_url'];
     $postImage = $_POST['post_image'];

     /* do your stuff here */
  }

Answer 3

变量名称可能存在问题。尝试这样的事情：

foreach ($pClass->retrieveAllInfo() as $data) {
    foreach ($pClass->retrieveBoards() as $boards) {
    }
}

如何为数组中的每个元素调用相同的函数？
