PHP development corporate website tutorial to add products
Let’s take a look at the code for adding a page:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>添加产品</title>
<style type="text/css">
#cnt{
width:400px;
height:400px;
margin-top:15px;
margin-left: 15px;
}
</style>
</head>
<body>
<div id="cnt">
<form method="post" action="addproduct.php" enctype="multipart/form-data">
产品名称:<input type="text" name="title" id="title"></br></br>
上传文件:<input type="file" name="myFile"></br></br>
产品价格:<input type="text" name="price"></br></br>
<input type="submit" value="添加产品">
</form>
</div>
</body>
</html>It’s nothing to add this piece, it’s mainly the html code. Pay attention to uploading files. We need to write enctype="multipart/form-data"# in the form. ##This is a code that is necessary to upload files
<?php
require_once('conn.php');
//接受文件，临时文件信息
$fileinfo=$_FILES["myFile"];//降维操作
$filename=$fileinfo["name"];
$tmp_name=$fileinfo["tmp_name"];
$size=$fileinfo["size"];
$error=$fileinfo["error"];
$type=$fileinfo["type"];
//服务器端设定限制
$maxsize=10485760;//10M,10*1024*1024
$allowExt=array('jpeg','jpg','png','gif');//允许上传的文件类型（拓展名
$ext=pathinfo($filename,PATHINFO_EXTENSION);//提取上传文件的拓展名
//目标存放文件夹
$path="../uploads";
if (!file_exists($path)) { //当目录不存在，就创建目录
mkdir($path,0777,true);//创建目录
chmod($path, 0777);//改变文件模式,所有人都有执行权限、写权限、度权限
}
//得到唯一的文件名！防止因为文件名相同而产生覆盖
$uniName=md5(uniqid(microtime(true),true)).".$ext";
//md5加密，uniqid产生唯一id，microtime做前缀
//目标存放文件地址
$destination=$path."/".$uniName;
//当文件上传成功，存入临时文件夹，服务器端开始判断
if ($error==0) {
if ($size>$maxsize) {
exit("上传文件过大！");
}
if (!in_array($ext, $allowExt)) {
exit("非法文件类型");
}
if (!is_uploaded_file($tmp_name)) {
exit("上传方式有误，请使用post方式");
}
//判断是否为真实图片（防止伪装成图片的病毒一类的
if (!getimagesize($tmp_name)) {//getimagesize真实返回数组，否则返回false
exit("不是真正的图片类型");
}
//move_uploaded_file($tmp_name, "uploads/".$filename);
if (@move_uploaded_file($tmp_name, $destination)) {//@错误抑制符，不让用户看到警告
echo "文件".$filename."上传成功!";
}else{
echo "文件".$filename."上传失败!";
}
}else{
switch ($error){
case 1:echo "超过了上传文件的最大值，请上传2M以下文件";break;
case 2:echo "上传文件过多，请一次上传20个及以下文件！";break;
case 3:echo "文件并未完全上传，请再次尝试！";break;
case 4:echo "未选择上传文件！";break;
case 7:echo "没有临时文件夹";break;
}
}
$title = $_POST['title'];
$imagename = $uniName;
$price = $_POST['price'];
$goodtime = time();
$sql = "insert into `product`(title,imgname,price,goodtime) values('$title','$imagename','$price','$goodtime')";
$res = mysql_query($sql);
if($res){
echo "<script>alert('添加产品成功');location.href='product.php';</script>";
}else{
echo "<script>alert('添加产品失败');location.href='product.php';</script>";
}
?>Here is the uploaded file After processing, and then adding it, if the uploaded file is not a legal file, an error message
will be prompted.
