消息：语法错误，意外＆＃39; $＆＃39;，期待变量（T_VARIABLE）

Answer 1

您需要正确命名变量。 $不是有效变量

function edit($)
{   
    // check if the appointment exists before trying to edit it
    $appointment = $this->Appointment_model->get_appointment($);

请将（$）更改为变量。例如（$ id）并更新get_appointment($id)

function edit($id)
{   
    // check if the appointment exists before trying to edit it
    $appointment = $this->Appointment_model->get_appointment($id);

解析错误：语法错误，意外＆＃39; $＆＃39;，在第17行的/var/www/html/cdf/application/models/Appointment_model.php中预期变量（T_VARIABLE）
