mysql查询没有插入数据库

Question

我正在构建一个简单的表单来让用户请求耗材,但在提交时它会不断给我一个通用错误.我不知道我的错误在哪里......

     CREATE TABLE `teacherrequests` (
  `name` varchar(64) NOT NULL,
  `binder` varchar(3) NOT NULL,
  `binderpage` varchar(2) NOT NULL,
  `binderdiv` varchar(2) NOT NULL,
  `calcr` varchar(2) NOT NULL,
  `chalkcolor` varchar(2) NOT NULL,
  `chalkwhite` varchar(2) NOT NULL,
  `chalkeraser` varchar(2) NOT NULL,
  `colpencil` varchar(2) NOT NULL,
  `dryerasecleaner` varchar(2) NOT NULL,
  `dryeraser` varchar(2) NOT NULL,
  `dryerasemarkers` varchar(2) NOT NULL,
  `filefolders` varchar(2) NOT NULL,
  `gluesticks` varchar(2) NOT NULL,
  `hangingfile` varchar(2) NOT NULL,
  `highlightermulti` varchar(2) NOT NULL,
  `highlighterone` varchar(2) NOT NULL,
  `holepunch3` varchar(2) NOT NULL,
  `holepunch1` varchar(2) NOT NULL,
  `index35` varchar(2) NOT NULL,
  `index57` varchar(2) NOT NULL,
  `markers` varchar(2) NOT NULL,
  `papergraph` varchar(2) NOT NULL,
  `paperlegal` varchar(2) NOT NULL,
  `papersteno` varchar(2) NOT NULL,
  `paperwhitelined` varchar(2) NOT NULL,
  `paperclipsbindlg` varchar(2) NOT NULL,
  `paperclipsbindmd` varchar(2) NOT NULL,
  `paperclipsbindsm` varchar(2) NOT NULL,
  `paperclipslg` varchar(2) NOT NULL,
  `paperclipsmd` varchar(2) NOT NULL,
  `paperclipssm` varchar(2) NOT NULL,
  `pencil` varchar(2) NOT NULL,
  `pencilsharp` varchar(2) NOT NULL,
  `pensblack` varchar(2) NOT NULL,
  `pensblue` varchar(2) NOT NULL,
  `pensgreen` varchar(2) NOT NULL,
  `pensred` varchar(2) NOT NULL,
  `permanentmarker` varchar(2) NOT NULL,
  `postit` varchar(2) NOT NULL,
  `postitsmall` varchar(2) NOT NULL,
  `stapler` varchar(2) NOT NULL,
  `staples` varchar(2) NOT NULL,
  `tapedbl` varchar(2) NOT NULL,
  `tapemasking` varchar(2) NOT NULL,
  `tapescotch` varchar(2) NOT NULL,
  `tapedispenser` varchar(2) NOT NULL,
  `tacks` varchar(2) NOT NULL,
  `clock` varchar(2) NOT NULL,
  `whiteout` varchar(2) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

这是代码......

我已经根据我的表格检查了这些,他们都匹配了.

$name = $_POST['name'];
$binder = $_POST['binder'];
$binderpage = $_POST['binderpage'];
$binderdiv = $_POST['binderdiv'];
$calc = $_POST['calc'];
$chalkcolor = $_POST['chalkcolor'];
$chalkwhite = $_POST['chalkwhite'];
$chalkeraser = $_POST['chalkeraser'];
$colpencil = $_POST['colpencil'];
$dryerasecleaner = $_POST['dryerasecleaner'];
$dryeraser = $_POST['dryeraser'];
$dryerasemarkers = $_POST['dryerasemarkers'];
$filefolders = $_POST['filefolders'];
$gluesticks = $_POST['gluesticks'];
$hangingfile = $_POST['hangingfile'];
$highlightermulti = $_POST['highlightermulti'];
$highlighterone = $_POST['highlighterone'];
$holepunch3 = $_POST['holepunch3'];
$holepunch1 = $_POST['holepunch1'];
$index35 = $_POST['index35'];
$index57 = $_POST['index57'];
$markers = $_POST['markers'];
$papergraph = $_POST['papergraph'];
$paperlegal = $_POST['paperlegal'];
$papersteno = $_POST['papersteno'];
$paperwhitelined = $_POST['paperwhitelined'];
$paperclipsbindlg = $_POST['paperclipsbindlg'];
$paperclipsbindmd = $_POST['paperclipsbindmd'];
$paperclipsbindsm = $_POST['paperclipsbindsm'];
$pencil = $_POST['pencil'];
$pencilsharp = $_POST['pencilsharp'];
$pensblack = $_POST['pensblack'];
$pensblue = $_POST['pensblue'];
$pensgreen = $_POST['pensgreen'];
$pensred = $_POST['pensred'];
$permanentmarker = $_POST['permanentmarker'];
$postit = $_POST['postit'];
$postitsmall = $_POST['postitsmall'];
$stapleremover = $_POST['stapleremover'];
$stapler = $_POST['stapler'];
$staples = $_POST['staples'];
$tapedbl = $_POST['tapedbl'];
$tapemasking = $_POST['tapemasking'];
$tapescotch = $_POST['tapescotch'];
$tapedispenser = $_POST['tapedispenser'];
$tacks = $_POST['tacks'];
$clock = $_POST['clock'];
$whiteout = $_POST['whiteout'];

我认为我的错误在这里,但我似乎无法找到它.

Answer 1

您应该做的第一件事是采用这种数据库设计并将其丢入垃圾箱.然后用这个设计替换它:

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_*功能并切换到使用PDO.

Answer 2

看一眼

 `calcr` varchar(2) NOT NULL,

在你的创建表代码上比较

$calc = $_POST['calc'];

在你的PHP代码中.我猜这只是一个简单的拼写错误,结尾有额外的"r".

我还发现这些代码行在另一个文件中没有附带的行:

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

  $stapleremover = $_POST['stapleremover'];

希望有所帮助!

[编辑]我没有看到您的插入和您的值之间有任何差异.所以现在我更多地看待这个,我认为我没有帮助解决问题.我只找到了一些你可能遗漏的数据.
