Question

我如何根据用户ID计算每张专辑的上传图片..我已经完成了这个但是不行......有些帮助表示赞赏。我是新学员！

这就是我所拥有的：

     Album db: |albumid|name|image|uid| <- user id 
     Gallery db: |galleryid|albumid|name|images|uid|

代码

 $sql = "
    SELECT COUNT(userid) 
      FROM tbl_gallery 
     where userid = 1
    ";
    $rs_result = mysql_query($sql,$con);
    $row = mysql_fetch_row($rs_result);
    $total_records = $row[0];
    echo $total_records;

    $sql = "SELECT * FROM tbl_album where userid = 1 ORDER BY albumid";
    $rs_result = mysql_query($sql,$con);


    ####### Fetch Results From Table ########

    while ($row = mysql_fetch_assoc($rs_result)) 
    {
        $aimage=$row['image'];
        $aid=$row['albumid'];
        $aname=$row['name'];

        <div class="pic">
    <?php 
        echo "<a href='includes/galeriefoto/gallery.php?id=1'> <img src='includes/galeriefoto/admin/acatch/$aimage' class='thumbimg' alt='Pic' alt='$aname'>"; 
    ?>
        <span class='pic-caption'>

            <center><p style='color:#000;font-size:24px'><?php echo $aname;?> (<?php echo $total_records;?>)</p></center>

        </span></a>
        </div>
   <?php } ?>

如果只是计算相册中的图像数量，以下内容就足以满足您的查询要求：

SELECT uid, albumid, COUNT(galleryid) as num_upload_images
FROM tbl_gallery
GROUP BY uid, albumid

这导致以下可能的输出：

[0] => [
    uid => 1,
    albumid => 1,
    num_upload_images => 15
],
[1] => [
    uid => 1,
    albumid => 2,
    num_upload_images => 12
]
