mysql查询没有插入到数据库中

-1

我正在构建一个简单的表单，让用户请求耗材，但是在提交时它一直给我一个通用的错误。我看不出我的错误是...mysql查询没有插入到数据库中

下面的代码...

我检查这些对我的形式，他们都投其所好。

$name = $_POST['name']; 
$binder = $_POST['binder']; 
$binderpage = $_POST['binderpage']; 
$binderdiv = $_POST['binderdiv'];

$whiteout = $_POST['whiteout'];

我假设我的错误在这里，但我似乎无法找到它。

// Insert data into mysql 

$sql="INSERT INTO teacherrequests(name, binder, binderpage, binderdiv, calcr,

$result=mysql_query($sql);

这里是的var_dump：

你遇到的一般错误是什么？ – dweiss

什么是错误信息？ – SeventotheSeven

你可以在$ result上做'var_dump'吗？如果它为空，那么'mysql_query'可能会遇到错误。 – philwinkle

相比

$calc = $_POST['calc'];

在你的PHP代码在

`calcr` varchar(2) NOT NULL,

您创建表的代码看看。我猜这只是一个简单的错字，最后加上额外的“r”。

我也发现了这几行代码并没有在其他文件中随附行：

`paperclipslg` varchar(2) NOT NULL, 
    `paperclipsmd` varchar(2) NOT NULL, 
    `paperclipssm` varchar(2) NOT NULL, 

    $stapleremover = $_POST['stapleremover'];

希望帮助！

[编辑]虽然我没有看到你的插入和你的值之间的任何差异。所以现在我再看看这些，我认为我没有帮助解决这个问题。我只发现了一些可能会丢失的数据。

他有'INSERT INTO teacherrequests（...，calcr，...）VALUES（...，$ calc，...）'所以我不认为就是这样。 –

第二部分解决了这个问题。数据库中缺少$ stapleremover，而其他变量未被传递。谢谢 – Joe

是的，我刚刚注意到calc vs calcr不会产生任何问题。这只是我头上的一个“错误”，因为我喜欢将所有数据命名为相同。 –

你应该做的第一件事就是采取这种数据库设计并把它扔进垃圾桶。然后用这种设计取代它：

CREATE TABLE teachingmaterials (
    id SMALLINT NOT NULL AUTO_INCREMENT, 
    name VARCHAR(64) NOT NULL, 
    PRIMARY KEY (id) 
) ENGINE=INNODB CHARACTER SET utf8; 

INSERT INTO 
    teachingmaterials 
    (name) 
VALUES 
    ('binder'), 
    ('binder-page'), 
    ('binder-div'), 
    -- put the rest of them in here -- 
    ('whiteout'); 

CREATE TABLE teacherrequests (
    id INT NOT NULL AUTO_INCREMENT, 
    name VARCHAR(64) NOT NULL, 
    PRIMARY KEY (id) 
) ENGINE=INNODB CHARACTER SET utf8; 

CREATE TABLE teacherrequests_teachingmaterials (
    teacherrequests_id INT NOT NULL, 
    teachingmaterials_id SMALLINT NOT NULL, 
    amount SMALLINT, 
    note VARCHAR(64), 
    PRIMARY KEY (teacherrequests_id, teachingmaterials_id) 
    FOREIGN KEY (teacherrequests_id) REFERENCES teacherrequests (id) ON DELETE CASCADE, 
    FOREIGN KEY (teachingmaterials_id) REFERENCES teachingmaterials (id) 
) ENGINE=INNODB CHARACTER SET utf8;

您还需要停止使用旧mysql_*功能，切换到使用PDO来代替。

谢谢。我会试试这个。我明显是新手，对db设计没有多少经验。 – Joe
