我有一个叫联系人的类。在这个类中，我有一个名为addContact（）的方法。第一个语句执行正确，但它似乎没有得到$ db-> lastInsertId（）。需要一些帮助。这里是我的代码：PHP类：不插入数据：第二个查询
public function addContact($addcontactfirstname,$addcontactmiddlename,$addcontactlastname,$addcontactstreetnumber, $addcontactstreetname, $addcontactsuburb, $addcontactcity, $addcontactemailhome, $addcontactemailwork,$addcontacthomephone, $addcontactcellphone, $addcontactworkphone){
$addsuccessfully = true;
$addcontact_id = 0;
try {
$db = database::databaseConnect();
$stmt1 = $db->prepare('INSERT INTO personalinfo (firstname, middlename, lastname) VALUES (:addcontactfirstname, :addcontactmiddlename, :addcontactlastname)');
$stmt1->bindParam(':addcontactfirstname', $addcontactfirstname, PDO::PARAM_STR);
$stmt1->bindParam(':addcontactmiddlename', $addcontactmiddlename, PDO::PARAM_STR);
$stmt1->bindParam(':addcontactlastname', $addcontactlastname, PDO::PARAM_STR);
$successful1 = $stmt1->execute();
$addcontact_id = $db->lastInsertId();
if($successful1){
//$addcontact_id = $db->lastInsertId();
$successful1 = true;
$stmt2 = $db->prepare('INSERT INTO contactinfo (contact_id, streetnumber, streetname, suburbname, cityname, emailhome, emailwork, homephone, cellphone, workphone) VALUES (:addcontact_id, :addcontactstreetnumber, addcontactstreetname, :addcontactsuburb, :addcontactcity, :addcontactemailhome, :addcontactemailwork,:addcontacthomephone, :addcontactcellphone, :addcontactworkphone)');
$stmt2->bindParam(':addcontact_id', $addcontact_id, PDO::PARAM_INT);
$stmt2->bindParam(':addcontactstreetnumber', $addcontactstreetnumber, PDO::PARAM_STR);
$stmt2->bindParam(':addcontactstreetname', $addcontactstreetname, PDO::PARAM_STR);
$stmt2->bindParam(':addcontactsuburb', $addcontactsuburb, PDO::PARAM_STR);
$stmt2->bindParam(':addcontactcity', $addcontactcity, PDO::PARAM_STR);
$stmt2->bindParam(':addcontactemailhome', $addcontactemailhome, PDO::PARAM_STR);
$stmt2->bindParam(':addcontactemailwork', $addcontactemailwork, PDO::PARAM_STR);
$stmt2->bindParam(':addcontacthomephone', $addcontacthomephone, PDO::PARAM_STR);
$stmt2->bindParam(':addcontactcellphone', $addcontactcellphone, PDO::PARAM_STR);
$stmt2->bindParam(':addcontacthomephone', $addcontactworkphone, PDO::PARAM_STR);
$successful2 = $stmt2->execute();
if($successful2){
$successful2 = true;
}
if(!$successful1 && !$successful2){
$addsuccessfully = false;
}
}
if($successful1 === true && $successful2 === true){
$addsuccessfully = true;
}
}
catch (PDOException $e) {
$addsuccessfully = false;
}
return $addsuccessfully;
}
我有一个函数，我从我的查看页面调用。这是我的功能：
function addContact($addcontactfirstname,$addcontactmiddlename,$addcontactlastname,$addcontactstreetnumber, $addcontactstreetname, $addcontactsuburb, $addcontactcity, $addcontactemailhome, $addcontactemailwork,$addcontacthomephone, $addcontactcellphone, $addcontactworkphone){
global $addsuccessfully;
contacts::addContact($addcontactfirstname,$addcontactmiddlename,$addcontactlastname,$addcontactstreetnumber, $addcontactstreetname, $addcontactsuburb, $addcontactcity, $addcontactemailhome, $addcontactemailwork,$addcontacthomephone, $addcontactcellphone, $addcontactworkphone);
return $addsuccessfully;
}
这里是我的页面，我称之为函数。该页面确实表示无法添加联系人。我知道第一个查询在联系人显示在数据库中时起作用，但它不会将第二位添加到数据库的contactinfo表中。这是我的看法页：
<?php
/*The first thing that need to take place on this page is to ensure that the $admin value = 1.
* If the value is not 1 the user will get redirected to the home page. If the value of
* $admin = null, it then indicates that the user is not logged in. The system will then tell the
* user that he need to logon first, but also warn the user that if he is not an admin user he won't be
* allowed access to this page. This is to ensure that the user don't type the url address in
* his browser to try and access this page. This means that only admin users will be able to
* view this page while logged on and will be able to add new users. This will be an admin
* protected page. Protcted so the user must be logged in and and admin user.

你能告诉我们我们需要的代码吗？你能把它分解成一个更简单的用例吗？ – 2013-02-26 02:00:37
