PHP錯誤不能弄明白是與SQL的東西，我覺得

Question

OK了錯誤的地方表示在本這裏代碼

if($error==false) { 

     $query = pg_query("INSERT INTO chatterlogins(firstName, lastName, gender, password, ageMonth, ageDay, ageYear, email, createDate) VALUES('$firstNameSignup', '$lastNameSignup', '$genderSignup', md5('$passwordSignup'), $monthSignup, $daySignup, $yearSignup, '$emailSignup', now());"); 
     $query = pg_query("INSERT INTO chatterprofileinfo(email, lastLogin) VALUES('$email', now())";); 
     $_SESSION['$userNameSet'] = $email; 
     header('Location: signup_step2.php'.$rdruri); 

    } 

人看到我做錯了什麼???起來對不起，因爲沒有特別說明，但一直盯着它10分鐘，我無法弄清楚。

Answer 1

$query = pg_query("INSERT INTO chatterprofileinfo(email, lastLogin) VALUES('$email', now())";); 

接近末尾的分號（;）放錯了位置。它應該在字符串中：

$query = pg_query("INSERT INTO chatterprofileinfo(email, lastLogin) VALUES('$email', now());"); 

Answer 2

在您的示例中，monthSignup，daySignup和yearSignup未被引用。

Answer 3

當查詢失敗時，pg_query（）返回false。 pg_last_error()返回上次操作的錯誤信息。
希望所有這些變量 - $ firstNameSignup，$ lastNameSignup，$ genderSignup ......除了$ passwordSignup-已通過正確pg_escape_string()

if($error==false) { 
    $query = " 
    INSERT INTO 
     chatterlogins 
     (
     firstName, lastName, gender, password, 
     ageMonth, ageDay, ageYear, email, createDate 
    ) 
     VALUES 
     (
     '$firstNameSignup', '$lastNameSignup', '$genderSignup', md5('$passwordSignup'), 
     $monthSignup, $daySignup, $yearSignup, '$emailSignup', now() 
    ) 
    "; 
    echo '<pre>Debug: query=', htmlspecialchars($query) , '</pre>'; 
    $rc = pg_query($query); 
    if (!$rc) { 
    die('pg_query failed: ' . htmlspecialchars(pg_last_error())); 
    } 


    $query = " 
    INSERT INTO 
     chatterprofileinfo 
     (email, lastLogin) 
    VALUES 
     ('$email', now()) 
    "; 
    echo '<pre>Debug: query=', htmlspecialchars($query) , '</pre>'; 
    $rc = pg_query($query); 
    if (!$rc) { 
    die('pg_query failed: ' . htmlspecialchars(pg_last_error())); 
    } 

    $_SESSION['$userNameSet'] = $email; 
    header('Location: signup_step2.php'.$rdruri); 
}
