php - PDO while 循环仅返回一行

Question

我已经为 PDO while 循环尝试了几种不同的版本，但它们都没有返回超过一行。问题在于循环中对dreamyPrizes 表的调用。如果我把它拿出来，它工作正常，它只返回一行。

我试过了：

  $st = $db->prepare("SELECT * FROM `dreamyAuctions` WHERE `showOnHomePage` =:yes AND `active`=:yes AND `completed`=:no ORDER BY `StartDate`"); // need to filter for next auction
$st->bindParam(':yes', $yes); // filter
$st->bindParam(':no', $no); // filter
$st->bindParam(':gameId', $gameId); // filter
$yes=1;
$no=0;
$st->execute();
$r = $st->fetch(PDO::FETCH_ASSOC);

<? 
while($r = $st->fetch(PDO::FETCH_ASSOC)){?>
<?
$auctionId= $r['id'];

$startDate = date("m-d-Y h:i A", strtotime($startDate));

if (strlen($title) > 100)
$title = substr($title, 0, 90) . '...</a>';

$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, FALSE);
$st = $db->prepare("SELECT * FROM `dreamyPrizes` WHERE `id`=:prizeId"); // need to    filter for next auction
$st->bindParam(':prizeId', $prizeId); // filter
$st->execute();
$r = $st->fetch(PDO::FETCH_ASSOC);
$prizeImage= $r['image1'];
$retailPrice= $r['retailPrice'];
 ?> 

 <div>div to loop</div> <? }?>

我也试过

do {

$auctionId= $r['id'];

$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, FALSE);
$st = $db->prepare("SELECT * FROM `dreamyPrizes` WHERE `id`=:prizeId"); // need to filter for next auction
$st->bindParam(':prizeId', $prizeId); // filter
$st->execute();
$rs = $st->fetch(PDO::FETCH_ASSOC);
$prizeImage= $rs['image1'];
$retailPrice= $rs['retailPrice'];

?>
<div>div to loop</div>
<?php } while ($r = $st->fetch(PDO::FETCH_ASSOC)); ?> 

Answer 1

必须将第二个表中的“st”更改为“sts”才能正常工作

$sts = $db->prepare("SELECT * FROM `dreamyPrizes` WHERE `id`=:prizeId"); // need to filter    for next auction
$sts->bindParam(':prizeId', $prizeId); // filter
$sts->execute();
$rs = $sts->fetch(PDO::FETCH_ASSOC);
$prizeImage= $rs['image1'];
$retailPrice= $rs['retailPrice'];`enter code here`

Answer 2

$sql = "SELECT p.* FROM `dreamyAuctions` a JOIN `dreamyPrizes` p 
        ON p.id = a.id
        WHERE `showOnHomePage` = 1 AND `active`= 0 AND `completed`= 0 
        ORDER BY `StartDate`";
$stm = $db->query($sql);
$data = $stm->fetchAll();

这就是您获取数据所需的全部内容。
现在您可以继续从分离的模板输出

<? foreach ($data as $row): ?>
<div>div to loop <?=$row['image1']?> <?=$row['retailPrice']?></div>
<? endforeach ?>
