mysql_fetch_assoc只返回1个结果

Question

mysql_fetch_assoc只取一个记录
PHP代码（东西都好检查数据库端）：

<?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

你不关闭HTML IMG标记。将/>添加到您的标记。

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