它確實顯示了一個用戶，但它顯示了我在桌面上的所有用戶，我只是在尋找一個用$ _session

我想顯示來自一個especific用戶的信息，並且我有一個$ _session 工作正常，但有一個表，在這種情況下，我不想使用表我必須使用CSS div，當我測試它時，告訴我這個錯誤注意：未定義索引：當這個「usuario」科莫從登錄索引文件

<?php 


require("conection/connect.php"); 

session_start(); 


$sql="SELECT stu_id, 
    f_name, 
    s_name, 
    l_name, 
    sl_name, 
    gender, 
    dob, 
    pob, 
    address, 
    phone, 
    email, 
    note 
    from tblstudents 
    where stu_id"; //i want to use a where stu_id='".$_SESSION['usuario']."'"; but it is not working show me Notice: Undefined index: usuario in C:\xampp\htdocs\studentskin\infostudent.php on line 2 
    $infostudent=mysql_query($sql);  // but when I did a test with where stu_id"; it is showing me the all users that I have on the table 


?>

while ($tblstudents=mysql_fetch_assoc($infostudent)){ 

     echo $tblstudents['stu_id']. 
     "<div>".$tblstudents['f_name']." ".$tblstudents['s_name']." ".$tblstudents['l_name']." ".$tblstudents['sl_name']."</div>"; 
     echo""; 
     }  
?>

//我想用$ _SESSION只是登錄我並告訴我信息我已記錄的所有信息

請問您可以發佈整個代碼嗎？ –

您可以粘貼$ _SESSION定義的代碼嗎？ – Jerry

if（isset（$ _ POST ['btn_log']））{ \t \t $ uname = $ _ POST ['unametxt']; \t \t $ pwd = $ _ POST ['pwdtxt']; \t \t $ _SESSION ['usuario'] = $ _POST ['unametxt']; \t \t \t \t $ _SESSION ['password'] = $ _POST ['pwdtxt']; \t \t \t \t \t \t \t \t $ _SESSION [ 'usuario'] = $ _POST [ 'unametxt']; \t \t \t \t \t \t $ _SESSION ['password'] = $ _POST ['pwdtxt']; \t \t $ SQL =請求mysql_query（「SELECT * FROM tbluser \t \t \t \t \t \t \t \t其中username = '$ UNAME' 和密碼= '$ PWD' \t \t \t \t \t \t \t \t \t \t \t \t \t \t \t「）; –
