Question

我有3张桌子，1）。移动，2）。 store1,3）。商店2 从表“移动”获取然后我们从表中收到4行记录。然后我将此行提取到store1和store2以获取其他详细信息。

请建议我需要做什么。

<?php
$mysqli = new mysqli("host" , "user" , "pass" , "database");
$result = $mysqli->query( "SELECT * FROM mobile WHERE live= '1' ") ;
while ( $rows =  $result->fetch_assoc() ) {

$store = $rows["store"];
$productId = $rows["productId"];
$store2 = $rows["store2"];
$productId2 = $rows["productId2"];

php?>

<?php
$result = $mysqli->query( "SELECT * FROM $store where productId='$productId' ") ;
while ( $rows =  $result->fetch_assoc() ) {

$title = $rows["title"];

$productImage = explode (",", $rows['imageUrlStr']);
$mrpPrice = explode (",", $rows['mrp']);
$offerPrice = explode (",", $rows['price']);
}

$result = $mysqli->query( "SELECT * FROM $store2 where productId= '$productId2'  ") ;
while ( $rows =  $result->fetch_assoc() ) {

$title2 = $rows["title"];

$productImage2 = explode (",", $rows['imageUrlStr']);
$mrpPrice2 = explode (",", $rows['mrp']);
$offerPrice2 = explode (",", $rows['price']);
} ?>

    <li class="mobile-box als-item">
        <div class="mobile-box-top">
            <div class="mobile-box-top-img"><img src="<?php echo $productImage[5]; ?>" alt="" title="" /></div>
            <div class="mobile-box-top-txt"><?php echo $title; ?></div>
            <div class="mobile-box-top-tag"><i class="fa fa-inr"></i> <?php echo $offerPrice[0]; ?></div>
        </div>
        <div class="mobile-box-bottom border-bottom">
            <div class="mobile-box-bottom-img"><img src="<?php echo $productImage2[5]; ?>" alt="" title="" /></div>
            <div class="mobile-box-bottom-txt"><?php echo $title2; ?></div>
            <div class="mobile-box-bottom-tag"><i class="fa fa-inr"></i> <?php echo $offerPrice2[0]; ?></div>
        </div>
        <div class="mobile-box-button"><a href="">Compare Now</a></div>
    </li>

你必须这样做

第1步：尝试获取这样的查询，因为您正在获取结果中的数据

所以试着这样做

$result1 = $mysqli->query( "SELECT * FROM $store where  productId= $result.productId ") ;

表二相同

我想从第一个表中获取数据然后我需要使用第一个表中的值从另一个表中获取第二个数据
