PHP 使用 MYSQL 表结果作为另一个查询的参数

Question

我的网站上有一个基于搜索从 MYSQL 中提取的表。 我希望能够单击添加到表中的按钮，该按钮会根据所选行打开更多数据。 在下图中，我有一列标记为第一个表的 ID，可用于 = ？ 在我的查询中，但我不知道如何首先将值设置为参数。 对解决此问题的最佳方法有任何想法吗？

我有$term = '%' . $_GET['itemID'] . '%'; $term = '%' . $_GET['itemID'] . '%'; 为第二个查询添加，但需要一种基于相应视图按钮绑定 ID 999999、1000000 或 1000001 的方法。 谢谢！

if(isset($_GET['term']))
    {   
       
        $term = '%' . $_GET['term'] . '%';
        $sql1 = "SELECT ID, Source, Contract_Number, Price_Effective, Price_Expiration, Min_Price, Average_Price
        FROM Both_Search WHERE SearchName LIKE ? LIMIT 10";

        $stmt = $conn->prepare($sql1); 
        $stmt->bind_param("s", $term);   
        $stmt->execute();
        $result1 = $stmt->get_result();
          while($row1 = $result1->fetch_assoc()) {
            echo "<td>" . $row1["ID"] . "</td>"; <----would want this to be the parameter for next query
            echo "<td>" . $row1["Source"] . "</td>";
            echo "<td><a target='_blank' rel='noopener noreferrer' href='contracts.php?number=" . $row1["Contract_Number"] . "'>" . $row1["Contract_Number"] . "</td>";
            echo "<td>" . $row1["Price_Effective"] . "</td>";
            echo "<td>" . $row1["Price_Expiration"] . "</td>";
            echo "<td>" . "$ " . $row1["Average_Price"] . "</td>";
            echo "<td>" . "$ " . $row1["Min_Price"] . "</td>"; ?>
                <td><button id="myBtn" type="button" class="btn btn-primary">View</button></td>
            </tr><?php

             }
            }
            
      
            
         
?>

Answer 1

您的 ID 为$row1["ID"] ，您可以将该 ID 用于Another Query 。

// Replace this
<td><button id="myBtn" type="button" class="btn btn-primary">View</button></td>
// To this
<td><a href="YOUR_PAGE_VIEW.php?id=<?= $row1["ID"]; ?>" id="myBtn"  class="btn btn-primary">View</a></td>

并且“查看”按钮将重定向到参数查询 ID = $row1["ID"] 的 YOUR_PAGE_VIEW.php。 现在，您在 YOU_PAGE_VIEW.php 中将 ID 作为变量$id用于另一个查询您想要的内容。

// In YOUR_PAGE_VIEW.php
$id = $_GET['id'];

希望这对你有帮助，
