尺寸查询

function get_size($id){
$result=mysql_query("SELECT size FROM mywishlist order by id") or die("My Wish Size Problem"."<br/><br/>".mysql_error());
while($row=mysql_fetch_array($result)){
return $row['size'];
}}

 function get_size($id){
 $result=mysql_query("SELECT size FROM mywishlist Where pid='$id'") or die("My Wish   Size Problem"."<br/><br/>".mysql_error());
 while($row=mysql_fetch_array($result)){
 return $row['size'];
}}

Mywishlist表格截图

当我使用此功能时

function get_size($id){

$result=mysql_query("SELECT size FROM mywishlist order by id") or die("My Wish Size Problem"."<br/><br/>".mysql_error());

while($row=mysql_fetch_array($result)){
 $size[] = $row['size'];
}

return $size;

}

 <?php foreach ($size as $sizes) { ?>
<div style="float: left;margin-left: 625px;margin-top: -131px;">
<font style="font-family:Arial,Helvetica,sans-serif;font-size:15px; color:#000;">
<?php echo $sizes; ?> 
<font><input type="hidden" name="size" value="<?php echo $size; ?>" />
</font></div><?php }?><br />

使用数组后的结果＆amp; Foreach循环

Answer 1

将您的功能更改为：

function get_size($id){

$result=mysql_query("SELECT size FROM mywishlist order by id") or die("My Wish Size Problem"."<br/><br/>".mysql_error());

while($row=mysql_fetch_array($result)){
 $size[] = $row['size'];
}

return $size;

}

因为在你的函数中你只返回第一行并且return返回while循环。
