mysql_fetch_assoc仅返回1个结果

Question

mysql_fetch_assoc只获取一条记录(检查数据库方面的情况都很好)

Php代码：

<?php 
$folder_id = $_GET['folder_id'];
$query = mysql_query("SELECT * FROM gallery_photos WHERE folder_id = $folder_id");

if (mysql_num_rows($query) == 0)
{
    echo '<h2>Sorry, you cannot change a folders photo cover if that folder has 
         no    photos in it<br /> <a href="gallery.albums.php?fder_id='
         .$folder_id.'">Back to the folder</a><h2>';
}
else
{
    while ($row = mysql_fetch_assoc($query))
    {
        echo '<img src="gallery_photos/'.$row['photo_name'].'" width="200"';
    }
}
?>

Answer 1

您没有关闭HTML IMG标记。将/>添加到标记中。

echo '<img src="gallery_photos/'.$row['photo_name'].'" width="200" />';
