我认为问题是初步准备好的声明作业

$stmt->$connect->prepare('SELECT id,pseudo,jeton FROM users  WHERE id=:id AND pseudo=:pseudo');

应该更像是这样。

$stmt = $connect->prepare('SELECT id, pseudo, jeton FROM users WHERE id=:id AND pseudo=:pseudo');

最终的sql查询肯定只有在成功添加头像的情况下才能运行？在寻找问题的同时进行了一些重组 - 希望它有所帮助。

if( $_SERVER['REQUEST_METHOD'] === 'POST' ) {
    if( !empty( $_SESSION['pseudo'] ) && !empty( $_SESSION['user_id'] ) ) {

        $id = trim( htmlspecialchars( $_SESSION['user_id'] ) );
        $pseudo = trim( htmlspecialchars($_SESSION['pseudo'] ) );
        /*
            Assign the prepared statement as a variable
        */
        $stmt = $connect->prepare('SELECT id, pseudo, jeton FROM users WHERE id=:id AND pseudo=:pseudo');
        if( !$stmt )exit('Failed to prepare sql');
        $stmt->execute( array(
                        ':id'       => $id,
                        ':pseudo'   => $pseudo
                    )
                );
        $row=$stmt->fetch();

        if( $_SESSION['pseudo'] == $row['pseudo'] && $_SESSION['user_id'] == $row['id'] ) {

            $avatarName     =   $_FILES['avatarCouverture']['name'];
