Question

我试图将MySQL中的数据插入到表中但是我似乎无法使循环正常工作：（

select语句是正确的，我不能让它正确地回显数据。

有什么想法吗？

编辑的代码低于我修正的：）

错误是

Parse error: syntax error, unexpected '(', expecting T_STRING or T_VARIABLE or '{' or '$' in /home/4507408/public_html/review.php on line 67

<?php

$sql  = "SELECT u.userID, p.productID, p.name, c.categoryname, r.reviewID, r.reviewTime, r.reviewData, u.firstname FROM review r INNER JOIN product p on p.productID = r.productID INNER JOIN user u on u.userID = r.userID INNER JOIN category c on c.categoryID = p.categoryID ORDER BY $sortby ASC;";

$query = $DBH->prepare($sql);
$query->execute();
$data = $query->fetchALL();
$originalDate = $row['reviewTime'];
$newDate = date("d-m-Y", strtotime($originalDate));
while($row = $data->(PDO::FETCH_ASSOC))                     
{

?>

<table class="rev">

<tr>
<th><a href="review.php?sort=name">Product Name:</a></th>
<th><a href="review.php?sort=categoryname">Category</a></th>
<th><a href="review.php?sort=reviewID">ID</a></th>
<th><a href="review.php?sort=reviewTime">Date</a></th>
<th><a href="review.php?sort=reviewData">Review</a></th>
<th><a href="review.php?sort=firstname">Reviewer's Name</a></th>
</tr>


<td><a href="viewproduct.php?productID=<?=$row['productID']?>"><?=$name?></a></td>
<td><?=$row['categoryname']?></td>
<td><?=$row['reviewID']?></td>
<td><?=$newDate?></td>
<td><?=$row['reviewData']?></td>
<td><?=$row['firstname']?></td>
</tr>

<?      } ?>

正确代码：

                                                <?php

                                                $sql  = "SELECT u.userID, p.productID, p.name, c.categoryname, r.reviewID, r.reviewTime, r.reviewData, u.firstname FROM review r INNER JOIN product p on p.productID = r.productID INNER JOIN user u on u.userID = r.userID INNER JOIN category c on c.categoryID = p.categoryID ORDER BY $sortby ASC;";

                                                $query = $DBH->prepare($sql);
                                                $query->execute();
                                                $data = $query->fetchALL();

                                                ?>

                                    <table class="rev">

                                                <th><a href="review.php?sort=categoryname">Category</a></th>

                                                </tr>

                                                <? foreach ($data as $row): ?>

                                                    <td><a href="viewproduct.php?productID=<?=$row['productID']?>"><?=$row['productID']?></a></td>
                                                    <td><?=$row['categoryname']?></a></td>
                                                    <td><?=$row['reviewID']?></a></td>

Answer 1

这一行没有任何意义：

while($row = $data->(PDO::FETCH_ASSOC))

我认为您需要的是based on the docs）

foreach ($data as $row)

因为fetchAll返回一个数组。

Answer 2

它应该是，

 $data = $query->fetchALL();
 foreach($data as $row)

而不是

  while($row = $data->(PDO::FETCH_ASSOC))

此外，

<?php  } ?>

直到你没有配置短语

<?   } ?>

Answer 3

@jon是正确的，你需要一个foreach循环，你需要将PDO :: FETCH_ASSOC放入$ query-＆gt; fetchAll（PDO :: FETCH_ASSOC）

php pdo用数据库中的数组填充表
