完整错误：解析错误：语法错误，意外的 '' (T_ENCAPSED_AND_WHITESPACE)，需要标识符 (T_STRING) 或变量 (T_VARIABLE) 或数字 (T_NUM_STRING)
It says that the error is on line 12. Here is what I have there:
它说错误在第 12 行。这是我在那里的内容：
$introduction="INSERT INTO Introduction (Title, Description)
VALUES ('$_POST[introtitle]','$_POST['introdescription']')";
Any help would be greatly appreciated!
任何帮助将不胜感激！

You have extra single quotes :
你有额外的单引号：
$introduction="INSERT INTO Introduction (Title, Description)
VALUES ('$_POST[introtitle]','$_POST[introdescription]')";
