好吧,我今天工作太久了,我被困在一些简单的事情上(我认为)
function commonData($uid)
{
if ($uid)
{
$sql = "
SELECT a.user_id, a.email, a.username, a.displayname, a.level_id, a.photo_id
FROM engine4_users AS a
WHERE a.user_id = ".$uid;
}
$UserInfo = @mysql_fetch_assoc(mysql_query($sql));
if ($UserInfo[user_id])
{
if ($UserInfo[photo_id] && $UserInfo[photo_id]!="NULL")
{
$PPhoto = @mysql_fetch_assoc(mysql_query("SELECT a.* FROM engine4_storage_files AS a WHERE a.file_id = ".$UserInfo[photo_id]));
$photo = SITE.$PPhoto[storage_path];
}
else $photo = NO_PHOTO;
$queryMoreProfile = mysql_query("SELECT * FROM engine4_user_fields_values AS a WHERE a.item_id = ".$UserInfo[user_id]);
while ($moreProfile = @mysql_fetch_assoc($queryMoreProfile))
{
//$location = '';
if ($moreProfile['field_id']==24)
{
$locationNumber = $moreProfile['value'];
$locationsql = @mysql_fetch_assoc(mysql_query("SELECT a.* FROM engine4_user_fields_options AS a WHERE a.option_id = ".$locationNumber));
if (isset($locationsql['label']) && !empty($locationsql['label']))
{
$location = $locationsql['label'];
}
}
//if(empty($location))
//{
// header("Location: http://www.fetishmen.net/members/edit/profile");
// exit;
//}
}
我想做的是,如果 $location
没有值(完全丢失数据库)重定向到页面。我在这里做错了什么?
最佳答案
数组$moreProfile
和$locationsql
的索引必须是变量或字符串,
if ($moreProfile['field_id']==24) //or $field_id
{
$locationNumber = $moreProfile['value']; //or $value
$locationsql = @mysql_fetch_assoc(mysql_query("SELECT a.* FROM engine4_user_fields_options AS a WHERE a.option_id = ".$locationNumber));
$location = $locationsql['label']; //or $label
}
if(empty($location))
{
header("Location: http://website.com");
exit;
}
编辑:根据OP的评论,
if ($moreProfile['field_id'] == 24 )
{
$locationNumber = $moreProfile['value']; //or $value
$locationsql = @mysql_fetch_assoc(mysql_query("SELECT a.* FROM engine4_user_fields_options AS a WHERE a.option_id = ".$locationNumber));
$location = $locationsql['label']; //or $label
} else if(empty($moreProfile['field_id'])) {
header("Location: http://website.com");
exit;
}
关于php - 如果数据丢失则重定向到页面,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/13388534/
