在php row循环中,只显示从mysql数据库中的一行??在forloop中,只从mysql数据库检索一个row,在任何时候从new product is entered?检索for loop repeat that size row again and again。
页面函数

当我使用这个函数时,
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& Foreach循环

将您的职能更改为:
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;
}因为在您的函数中,您只返回了第一行,返回终止了while循环。
