Question

在SELECT中显示所有选定数据条目时出现问题。现在唯一显示的是recipe_direct数据。每个表数据应在一行中列出名称，个人资料，直接，身份验证名称和身份验证电子邮件。

  <div class="starter-template">
    <h1>Recipes</h1>
  </div>
  <?php
    try
    {
      $sql = 'SELECT recipe_id, recipe_name, recipe_ingred, recipe_direct, author_name, author_email FROM recipes';
      $result = $pdo->query($sql);
    }
    catch (PDOException $e)
    {
      $error = 'Error fetching recipes: ' . $e->getMessage();
    }
    while ($row = $result->fetch())
    {
      $recipes[$row['recipe_id']] = $row;
    }
  ?>

  <p><a href="addrecipe.php">Add a Recipe</a></p>
  <?php foreach ($recipes as $id => $recipe): ?>
    <blockquote>
      <table class="table table-striped">
        <tr>
          <td><?php echo $recipe['recipe_name']; ?></td>
          <td><?php echo $recipe['recipe_ingred']; ?></td>
          <td><?php echo $recipe['recipe_direct']; ?></td> 
          <td><?php echo $recipe['author_name']; ?></td> 
          <td><?php echo $recipe['author_email']; ?></td>
        </tr>
          <?php htmlout($recipe_html); ?> | 
          <a href="updaterecipe.php?id=<?php echo $id; ?>">edit</a> |
          <a href="deleterecipe.php?id=<?php echo $id; ?>">delete</a>
      </table>
    </blockquote>
  <?php endforeach; ?>

Answer 1

每次为其分配值时都会覆盖$recipe_html

为什么不回显表行：

  <table>
     <?php foreach ($recipes as $id => $recipe): ?>
     <tr>
      <td><?= $recipe['recipe_name']; ?></td>
      <td><?= $recipe['recipe_ingred']; ?></td>
      <td><?= $recipe['recipe_direct']; ?></td> 
      <td><?= $recipe['author_name']; ?></td> 
      <td><?= $recipe['author_email']; ?></td>
    </tr>
  <?php endforeach; ?>
 </table>

EdIt 作为@Fred -ii-状态，表标签应该在循环之外

Answer 2

在foreach之前，所有内容都是正确的。

<blockquote>
  <table class="table table-striped">
   <?php foreach ($recipes as $id => $recipe): ?>
    <tr>
      <td><?php $recipe_html = $recipe['recipe_name']; ?></td>
      <td><?php $recipe_html = $recipe['recipe_ingred']; ?></td>
      <td><?php $recipe_html = $recipe['recipe_direct']; ?></td> 
      <td><?php $recipe['author_name']; ?></td> 
      <td><?php $recipe['author_email']; ?></td>
    </tr>
    <p> //seems you were missing opening <p> tag//
      <?php htmlout($recipe_html); ?> | 
      <a href="updaterecipe.php?id=<?=$id?>">edit</a> | //can use shorthand here//
      <a href="deleterecipe.php?id=<?=$id?>">delete</a> //can use shorthand here//
    </p>
    <?php endforeach; ?>
   </table>
