所以我过去几天一直试图让这个页面正常工作。至于数据库操作和它不是什么工作就像一个魅力。问题是它显然没有使用我的javascript函数重定向回自身。它将显示一个大多数空白页面，网址中没有$ _GET变量，这让我相信问题实际上是在我的php函数而不是我的javascript函数。
function edit_player()
{
try{
if( isset( $_GET['player_id'] ) )
{
if( isset( $_GET['success'] ) && $_GET['success'] )
{
echo "<div class='success'> You have successfully edited this players info.</div>" ;
}
$playerid = $_GET['player_id'] ;
$db = honneyconnect( ) ; // db connection established
if( mysqli_connect_error() )
{
throw new Exception( "Could not connect to the database") ;
}
$query = 'select * from roster where player_number ="'.$playerid.'"' ;
$player = $db->query( $query ) ;
if( !$player )

答案 0 :(得分：0)
success_redirect( ".$url." )
should be
success_redirect( '".$url." ')
为什么不使用标题功能
header("Location: $url");
