将图像上传到网络服务器并将路径存储在数据库中

Question

我正在尝试使用 php 将图像上传到我的网络服务器并将图像的路径存储在 mysql 数据库中，我无法执行此操作。任何帮助，将不胜感激。当我点击提交时，我可以看到一个空白的 php 页面..

post.php

<?php


$dbhost = "localhost";
$dbuser = "root";
$dbpass = "";

$name = $_POST['ctitle'];
$description = $_POST['cdesc'];
$image = $_FILES['image']['name'];
$filepath = "images/";
$filepath = $filepath . basename($image);

if(move_uploaded_file($image, $filepath)){
$con = mysql_connect($dbhost, $dbuser, $dbpass);
if(! $con )
{
  die('Could not connect: ' . mysql_error());
}
$sql="INSERT INTO bbmp (dt,title,description,filename,img_path)
VALUES (NOW(), '$name','$description','$image','$filepath')";

mysql_select_db('bbmp',$con);
$retval = mysql_query( $sql, $con );
if(! $retval )
{
  die('Could not enter data: ' . mysql_error());
}
echo "Entered data successfully\n";
mysql_close($con);
}

?>

sql

CREATE TABLE IF NOT EXISTS `bbmp` (
  `id` int(100) unsigned NOT NULL AUTO_INCREMENT,
  `dt` datetime NOT NULL,
  `title` varchar(255) NOT NULL,
  `description` varchar(255) NOT NULL,
  `filename` varchar(255) NOT NULL,

上传文件时需要有效的加密类型：enctype="multipart/form-data"

改为：

  <form method="POST" action="post.php" enctype="multipart/form-data">

你也需要把变量改成这个，因为 $_FILES['image']['name'] 只是一个名字，所以把这个改成运行 move_uploaded_file()函数

 $image = $_FILES['image']['tmp_name'];
