列数与INSERT语句中第1行错误的值计数不匹配？

Question

我有这个代码将数据INSERT到mysql表中。对我来说一切似乎都没关系，因为我刚刚编辑了另一个具有相同列名的表中的代码，但是这个代码给出了错误。

// Escape user inputs for security

$facultyid = mysqli_real_escape_string($link, $_REQUEST['facultyid']);

$coursename = mysqli_real_escape_string($link, $_REQUEST['coursename']);

$coursecode = mysqli_real_escape_string($link, $_REQUEST['coursecode']);

$level = mysqli_real_escape_string($link, $_REQUEST['level']);

$semester = mysqli_real_escape_string($link, $_REQUEST['semester']);

$year = mysqli_real_escape_string($link, $_REQUEST['year']);

$cee = mysqli_real_escape_string($link, $_REQUEST['cee']);

// attempt insert query execution 

$sql = "INSERT INTO courses (facultyid, coursename, coursecode, level, semester, year, cee)

VALUES ('$facultyid', '$coursename', '$coursecode', '$level' '$semester', '$year', '$cee')";

任何帮助？

Answer 1

您错过了“$ level”＆＃39;＆＃39; $ semester＆＃39;

之间的昏迷（，）

VALUES ('$facultyid', '$coursename', '$coursecode', '$level', '$semester', '$year', '$cee')";
