Question

这是我用来发布id的值并在下一页上重现该id的代码

<?php
              global $row6;
              $query= "select s.name ,s1.price from services s ,seller_services s1 where s1.service_id = s.id LIMIT 7;";
              $result= mysqli_query($conn3,$query) or die(mysqli_error($conn3));
              while($row6=mysqli_fetch_array($result))
              {
                ?>
              <div class="col-md-3 col-sm-4">
                <div class="pro-box">
                  <div class="pro-thumb"><img src="https://udemy-images.udemy.com/course/240x135/1192700_6496_2.jpg" alt=""></div>
                  <div class="pro-txt"> <a href="#" class="add2cart"><i class="fa fa-shopping-cart"></i></a>
                    <h6><a href=""><?php echo $row6['name'];?></a></h6>
                    <p class="price"><i class="fa fa-inr" aria-hidden="true"></i><?php echo $row6['price'];?></p>
                    <form action="manageservice.php" method="POST">
                       <button name="buy"><input type="submit" hidden="id" value="buy" name="buy"/></button>
                     </form>
                     <div class="pro-rating"><a href="#"><i class="fa fa-star"></i> <i class="fa fa-star"></i> <i class="fa fa-star"></i> <i class="fa fa-star"></i> <i class="fa fa-star"></i></a></div>
                  </div>
                </div>
              </div>
              <?php } ?> 

这是我用来接收id的值的代码，但它没有显示任何我不知道的

<div class="team-page">
      <div class="container">
        <div class="row"> 
           <?php 
          global $row;
          if(isset($_POST['buy']))
                                    {
                                        $id=$_POST['id'];
          $query5= "Select *from services where id = '$id'; ";
          $result=mysqli_query($conn3,$query5) or die("Mysql error");

           while($row=mysqli_fetch_array($result))
                                        {
                                          ?>

                      </ul>
                    </div>
                  </li>
                </ul>
              </div>
          </div>
          <?php } ?>
          <?php } ?>

所以现在的问题是，id不会收到任何价值或者我无法弄清楚该怎么做的事情请帮助人们

Answer 1

根据我以前的不完整答案：我认为您的问题是您尝试显示$row的值，但是在while($row=mysqli_fetch_array($result))循环之外。我试图修复你的代码。尝试一下，让我知道它是否正常工作，或者是否有任何错误。

<div class="team-page">
      <div class="container">
        <div class="row"> 
          <?php 
              global $row;
              if(isset($_POST['buy'])) {             
                  $id=$_POST['id'];
                  $query5= "Select *from services where id = '$id'; ";
                  $result=mysqli_query($conn3,$query5) or die("Mysql error");
             }
          ?>
