php将变量移动到另一个文档

你好，所以我现在有一个小问题，基本上我有一个while循环，它从数据库输出一个名为job的表，还有一个链接到bid.php的bid按钮。当按钮带我到页面时，我希望它带着点击该按钮的行的jobid，这样我就可以在我的数据库中输入特定的值。有人对如何移动有任何想法吗？目前我正在尝试使用post来执行此操作，但我不断得到错误，变量dosnt似乎正在移动。我只是得到一个空白页，然后不显示id。
以下是findjob22.php：

<?php
require 'config.php';
if(isset($_POST['submit']))
{
    $valueToSearch = $_POST['valueToSearch'];
    // search in all table columns
    // using concat mysql function
    $query = "SELECT * FROM `job` WHERE CONCAT(`job_id`,`location`, `description`, `budget`, `duedate`,`title`) LIKE '%".$valueToSearch."%'";
    $search_result = filterTable($query);

}
 else {
    $query = "SELECT * FROM `job`";
    $search_result = filterTable($query);
}

// function to connect and execute the query
function filterTable($query)
{
    $conn = mysqli_connect("localhost", "root", "", "bid4myjob");
    $filter_Result = mysqli_query($conn, $query);
    return $filter_Result;
}

?>

下面是bid.php，我试图从findjob22.php获取行的特定id：

<?php
// include "job.php" 
$jobid    = $_POST['job_id'];
echo "$jobid"
 ?>
<!--<html>
<div class="col-xs-8">

<div class="page-header white-content">
    <h1><?= _('Your Bid') ?>.</h1>
</div>

<div class="white-content">
    <div class="well">

            <br/><br/>
            <form method="post" action="/listings/bid/<?//=$listingID; ?>/confirm" class="form-horizontal">
                <input type="hidden" value="<?=//$bid_amount?>" class="input-medium" name="bid_amount"/>
                <input type="submit" name="sb_bid" value="<?php// echo _('I agree and I confirm my BID'); ?>" class="btn btn-medium btn-green" />
            </form>

    </div>

</div>

</div>

</html>-->

我不确定您是否可以在submit按钮中传递值，但是您可以使用隐藏的输入来传递值。

<input type="hidden" value="<?php echo $row['job_id']; ?>" name="job_id" />
<input type="submit" class="btn btn-xlarge btn-block btn-primary">bid</input>

如果你想让它像你有它一样工作，用一个按钮。

<button type="submit" 
        name="job_id" 
        value="<?php echo $row['job_id']; ?>"
        class="btn btn-xlarge btn-block btn-primary">
    bid
</button>

如果您还想传递一些数据：

<form method="post" 
      action="bid.php" 
      class="form-horizontal">
    <div class="input-group">
        <input type="text"  
               class="form-control" 
               name="bid" 
               id="bid" required />
    </div>
    <button type="submit" 
            name="job_id" 
            value="<?php echo $row['job_id']; ?>"
            class="btn btn-xlarge btn-block btn-primary">
        bid
    </button>
    <br/>
</form>

那你就有机会了 $_POST["job_id"] 以及 $_POST["bid"] 在bid.php中
