submitAlbumForm.php，用于将表单信息上载到数据库的php表单

<?php
include "base.php";

//Setting up images directory
$target = "images/"; 
$target = $target . basename( $_FILES['albumCover']['name']);

$albumCover=($_FILES['albumCover']['name']); 

//inserting data order
$order = "INSERT INTO albums
            (artistName, albumName, releaseDate, leakDate, whereItLeaked, albumCover)
            VALUES
            ('$_POST[artistName]',
            '$_POST[albumName]',
            '$_POST[releaseDate]',
            '$_POST[leakDate]',
            '$_POST[whereItLeaked]',
            '{$_FILES['albumCover']['name']}')";

 //Writes image to database
 mysql_query("INSERT INTO `albums` VALUES ('albumCover')") ; 

  if(move_uploaded_file($_FILES['albumCover']['tmp_name'], $target)) 
 { 

 //Tells you if its all ok 
 echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded, and your information has been added to the directory"; 
 } 
 else { 

 //Gives an error if its not 
 echo "Sorry, there was a problem uploading your file."; 
 } 

//declare in the order variable
$result = mysql_query($order);  //order executes
if($result){
    echo("<br>Thank you for submitting!");
} else{
    echo("<br>Sorry, something went wrong! Please try again!");
}
?>

乍一看，您的图像大小调整代码位于
if（isset（$\u POST['submit']）中{
检查您的表单，但是当表单提交到
submitAlbumForm.php
这是一个完全不同的页面时，此代码将永远不会运行。我认为您只需要将调整大小的代码移动到submitAlbumForm.php，可能在
if（move_uploaded_文件（…）中
根据需要阻止并更改路径。
我看不出if如何阻止
if（isset（$\u POST['submit']））
一旦被点击，如果被点击，图像数据将直接输出，这将不起作用，因为它被HTML包围。一个单独的脚本输出大小调整后的图像的数据，将由一个单独的脚本更合适地处理。（可能是一个以GET params作为大小的脚本？）如果您试图保存图像的已调整大小的副本而不是原始大小的图像，那么您可能应该在
move\u uploaded\u file
之后执行此操作。您可能可以使用
SimpleImage:：save（）
来执行此操作。这可能会起作用：


if(move_uploaded_file($_FILES['albumCover']['tmp_name'], $target)) 
{ 
    require_once 'SimpleImage.php';
    $image = new SimpleImage();
    $image->load($target);
    $image->resize(150,150);
    $image->save($target); // Overwrites the image with a resized one

    // Tells you if its all ok 
    echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded, and your information has been added to the directory"; 
} 
else ...



你可以试试我自己的程序。
我上传和存储的数据和图像的大小可以减少，我们可以改变

我使用php和xampp。
目录：


C:\xampp\htdocs\phpyan\6_Database_2
6_Database_2 :
..images (dir)
..packages (dir)
..input_personal_info.php (file)

..images
   ..small(dir)
   ..more pict (file picture)
-----------------------------
..packages
   ..ClassDatabase.php 
   ..Personal.php


“图像文件夹”中有一个名为“小”的文件夹

注:
在package文件夹中，我保存了一些类，它们可以作为存储数据和上传小尺寸图像的功能

输入_personal_info.php

那么..你希望我们阅读所有这些内容吗？到底哪里出错了？这会更有帮助；）Stackoverflow不是一种调试服务。你必须问一个与编程相关的特定问题，向我们展示你代码的相关部分（而不是数百行）抱歉，我想我不是很清楚哈哈，除了html表单中的php部分，其他一切都正常工作，在上传到我的数据库之前，它实际上没有调整图像大小和保存图像。哪些代码部分是submitAlbumForm.php？你得到的php错误是什么？没错，就是这样。不仅仅是在，但他引用了
$\u文件['albumCover']['name']
也在该页面上，因此他正在从请求中重新提取整个图像，即使它已被调整大小并保存在某个地方。非常感谢您的回复！确实帮了我很多忙！就是这样！非常感谢您的帮助！太好了！我没有检查代码，所以我很幸运。很高兴它帮了我的忙。
