我正在处理库存管理系统项目，我正在使用JQuery，Php和MySql。主页工作正常。每当我尝试编辑现有表或尝试添加更多库存时，就会发生错误。 我创建
时收到此错误消息Notice: Undefined index: stock_status in C:\xampp\htdocs\stock\create.php on line 14
Notice: Undefined index: date_supplied in C:\xampp\htdocs\stock\create.php on line 15
SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'stock_descr' cannot be null
我没有收到update.php的错误消息，只是在运行脚本后它永远不会更新我的表。
这是我的表结构
CREATE TABLE IF NOT EXISTS `stock` (
`stock_id` tinyint(5) NOT NULL AUTO_INCREMENT,
`stock_name` varchar(20) NOT NULL,
`stock_categ` varchar(20) NOT NULL,
`stock_descr` varchar(50) NOT NULL,
`stock_comp` varchar(20) NOT NULL,
`stock_supp` varchar(20) NOT NULL,
`stock_quan` int(11) NOT NULL,
`cost` int(11) NOT NULL,
`stock_status` enum('Available','Inavailable') NOT NULL,
`date_supplied` date NOT NULL,
PRIMARY KEY (`stock_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=10 ;
我在表中添加项目的代码是 create.php
<?php
require_once 'dbconfig.php';
if($_POST)
{
$stock_name = $_POST['stock_name'];
$stock_categ = $_POST['stock_categ'];
$stock_descr = $_POST['stock_descr'];
$stock_comp = $_POST['stock_comp'];
$stock_supp = $_POST['stock_supp'];
$stock_quan = $_POST['stock_quan'];
$cost = $_POST['cost'];
$stock_status = $_POST['stock_status'];
$date_supplied = $_POST['date_supplied'];
try{
$stmt = $db_con->prepare("INSERT INTO stock(stock_name,stock_categ,stock_descr,stock_comp,stock_supp,stock_quan,cost,stock_status,date_supplied) VALUES(:sname, :scateg, :sdescr,:scomp, :ssupp, :squan,:scost, :sstatus, :ssupplied)");
$stmt->bindParam(":sname", $stock_name);
$stmt->bindParam(":scateg", $stock_categ);
$stmt->bindParam(":sdescr", $$stock_descr);
$stmt->bindParam(":scomp", $stock_comp);
$stmt->bindParam(":ssupp", $stock_supp);
$stmt->bindParam(":squan", $stock_quan);
$stmt->bindParam(":scost", $cost);
$stmt->bindParam(":sstatus", $stock_status);
$stmt->bindParam(":ssupplied", $date_supplied);
if($stmt->execute())
{
echo "Successfully Added";
}
else{
echo "Query Problem";
}
}
catch(PDOException $e){
echo $e->getMessage();
}
}
?>
我在桌子上编辑项目的代码是 update.php
<?php
require_once 'dbconfig.php';
if($_POST)
{
$id = $_POST['id'];
$stock_name = $_POST['stock_name'];
$stock_categ = $_POST['stock_categ'];
$stock_descr = $_POST['stock_descr'];
$stock_comp = $_POST['stock_comp'];
$stock_supp = $_POST['stock_supp'];
$stock_quan = $_POST['stock_quan'];
$cost = $_POST['cost'];
$stock_status = $_POST['stock_status'];
$date_supplied = $_POST['date_supplied'];
$stmt = $db_con->prepare("UPDATE stock SET stock_name=:sn, stock_categ=:sc, stock_descr=:sd,stock_comp=:sc,stock_supp=:ss,stock_quan=:sq,cost=:c,stock_status=:ss,date_supplied=:ds WHERE emp_id=:id");
$stmt->bindParam(":sn", $stock_name);
$stmt->bindParam(":sc", $stock_categ;
$stmt->bindParam(":sd", $stock_descr);
$stmt->bindParam(":sc", $stock_comp);
$stmt->bindParam(":ss", $stock_supp);
$stmt->bindParam(":sq", $stock_quan);
$stmt->bindParam(":c", $cost);
$stmt->bindParam(":ss", $stock_status;
$stmt->bindParam(":ds", $date_supplied);
$stmt->bindParam(":id", $id);
if($stmt->execute())
{
echo "Successfully updated";
}
else{
echo "Query Problem";
}
}
?>
这是向表格添加更多项目的表格
<style type="text/css">
#dis{
display:none;
}
</style>
<div id="dis">
<!-- display message here -->
</div>
<form method='post' id='stock-SaveForm' action="#">
<table class='table table-bordered'>
<tr>
<td>Stock Name</td>
<td><input type='text' name='stock_name' class='form-control' placeholder='EX : Piriton' required /></td>
</tr>
<tr>
<td>Category</td>
<td><input type='text' name='stock_categ' class='form-control' placeholder='EX : Tablet' required></td>
</tr>
<tr>

<tr>

<button type="submit" class="btn btn-primary" name="btn-save" id="btn-save">
<span class="glyphicon glyphicon-plus"></span> Save this Record
</button>
</td>
</tr>
</table>
</form>
我的jquery是
// JavaScript Document
$(document).ready(function(){
/* Data Insert Starts Here */
$(document).on('submit', '#stock-SaveForm', function() {
$.post("create.php", $(this).serialize())
.done(function(data){
$("#dis").fadeOut();
$("#dis").fadeIn('slow', function(){
$("#dis").html('<div class="alert alert-info">'+data+'</div>');
$("#stock-SaveForm")[0].reset();
});
});
return false;
});
/* Data Insert Ends Here */
/* Data Delete Starts Here */
$(".delete-link").click(function()
{
var id = $(this).attr("id");
var del_id = id;
var parent = $(this).parent("td").parent("tr");
if(confirm('Sure to Delete ID no = ' +del_id))
{
$.post('delete.php', {'del_id':del_id}, function(data)
{
parent.fadeOut('slow');
});
}
return false;
});
/* Data Delete Ends Here */
/* Get Edit ID */
$(".edit-link").click(function()
{
var id = $(this).attr("id");
var edit_id = id;
if(confirm('Sure to Edit ID no = ' +edit_id))
{
$(".content-loader").fadeOut('slow', function()
{
$(".content-loader").fadeIn('slow');
$(".content-loader").load('edit_form.php?edit_id='+edit_id);
$("#btn-add").hide();
$("#btn-view").show();
});
}
return false;
});
/* Get Edit ID */
/* Update Record */
$(document).on('submit', '#stock-UpdateForm', function() {
$.post("update.php", $(this).serialize())
.done(function(data){
$("#dis").fadeOut();
$("#dis").fadeIn('slow', function(){
$("#dis").html('<div class="alert alert-info">'+data+'</div>');
$("#stock-UpdateForm")[0].reset();
$("body").fadeOut('slow', function()
{
$("body").fadeOut('slow');
window.location.href="index.php";
});
});
});
return false;
});
/* Update Record */
});
有人能告诉我我应该做的事情，我没有注意到或我的错误。感谢
答案 0 :(得分：2)
$stmt->bindParam(":sdescr", $$stock_descr);
应该是
$stmt->bindParam(":sdescr", $stock_descr);
