因為它只顯示 id 而不是我的 index.php 中的表信息

Question

目前我正在讓我的產品顯示它們的狀態“可用”或“缺貨”在我的數據庫中創建一個名為“estado”的新表......在我的產品表中添加一個名為“estado_id”的新列，它存儲在什么狀態是產品。

數據庫圖像：

埃斯塔多

產品展示

然后當放置它以便它顯示在我在 index.php 中的產品列表中時，它看起來只是狀態表的 ID。 例如，在下圖中，它顯示“1”，我需要顯示產品的狀態，以說明它是否有貨或缺貨。

INDEX.PHP 3 中的產品

索引.php

    <div class="productos">
        <a href="productos/producto.php?id=<?php echo $productos['id']?>">
  <img src="<?php echo '/images/' . $productos['image']; ?>" class="img-test">
  <p class="text-test"><?php echo $productos['title']?></p>
            

            <p class="status"><?php echo $productos['tipo_id']; ?></p>
 
            
            
        </a>
</div>

Answer 1

您需要對第二個表進行左連接，例如：

SELECT t1.*, t2.name as estado FROM productos AS t1 LEFT JOIN estados as t2 ON (t1.estado_id = t2.id)

然后在html上：

<p class="status"><?php echo $productos['estado']; ?></p>
