我在PHP中使用脚本将数据存储在数据库中。该脚本名为functions.php，这是它的内容：
class LoginRegister{
function __construct($db){
$this->db= $db;
}
public function regEventoPreesc($evento1,$desc1,$evento2,$desc2){
$query = $this->db->prepare("INSERT INTO 001_preesc(dia,descripcion) VALUES (?,?),(?,?),(?,?),(?,?)");
$query->execute(array($evento1,$desc1,$evento2,$desc2));
return true;
}
public function regEventoPrim($evento1,$desc1,$evento2,$desc2){
$query = $this->db->prepare("INSERT INTO 002_prim(dia,descripcion) VALUES (?,?),(?,?),(?,?),(?,?)");
$query->execute(array($evento1,$desc1,$evento2,$desc2));
return true;
}
public function regEventoSecu($evento1,$desc1,$evento2,$desc2){
$query = $this->db->prepare("INSERT INTO 003_secu(dia,descripcion) VALUES (?,?),(?,?),(?,?),(?,?)");
$query->execute(array($evento1,$desc1,$evento2,$desc2));
return true;
}
public function regMes($mes){
$query = $this->db->prepare("INSERT INTO mes(mes) VALUES (?)"); //LINE 29
$query->execute(array($mes));
return true;
}
}
当我调用regMes函数时，它会正确地将数据存储在de数据库中，但是当我通过html表单调用regEventoSecu，regEventoPrim和regEventePreesc函数时，我收到此错误：
PHP致命错误：未捕获异常'PDOException'，消息'SQLSTATE [42S22]：未找到列：1054 /home/noewebst/public_html/act_eventos/functions.php中'字段列表'中的未知列'dia'： 29 堆栈跟踪：
