在PHP中使用MySQL存储过程插入数据

Question

使用MySQL存储过程通过PHP PDO插入表中

<?php

$emp = $_SESSION["emp_id"];
$date = date('Y-m-d');
if (isset($_POST['btn-upload'])) {
    try {
        $connection = new PDO($dsn, $username, $password, $options);

        $sql = "CALL 'ins' (:form_no,:activity_name,:emp,:dates);";
        $statement = $connection->prepare($sql);
        $statement1->bindParam(":form_no", $_POST['form_no']);
        $statement1->bindParam(":activity_name", $_POST['activity_name']);
        $statement1->bindParam(":emp", $emp);
        $statement1->bindParam(":dates", $date);
        $statement->execute();
    } catch (PDOException $error) {
        echo $sql . "<br>" . $error->getMessage();
    }
    if ($statement->rowcount() == 1) {
    }
}

当我点击“提交”时，我的页面显示处理没有任何反应。 在myphpadmin中
