php批量上传图片并把图片名放入数据库
前几天工作中要做这样一个功能,有八百多个系统 生成的会员;给这八百多个系统会员上传图片;然后把图片名放入数据库。
第一步:
第一步肯定是首先把图片上传到对应的图片目录下,直接用框架中已经有的上传类:
<?php try { $upload=new Upload(); $upload->set_ext(array('zip')); $path='目录名'; if ( ! Io::mkdir($path)) // 创建目录 { throw new Exception("无法创建文件上传目录:$path"); } $upload->set_path($path); if(!$upload->is_allow_ext($_FILES['files']['name'])) { $this->show_message('必须zip格式数据', '0', NULL, TRUE); } $result=$upload->save($_FILES['files']); $archive = new Archive_Zip(); $archive->set_target($path)->decompress($result['file']); unlink($result['file']);//删除使用后的zip; $this->show_message('导入成功', '1', array(array('text'=>'返回导入页面','href'=>'***跳转的链接地址***')),TRUE); }catch(Exception $e){ $this->show_message('图片导入失败', '0', NULL, TRUE); } } ?>
第二步:
图片上传完成后,就应该把目录下所有的系统会员图片名称取出来,那就得用遍历了。想想也不用那么麻烦了,php自带函数glob();
glob() 函数返回匹配指定模式的文件名或目录。
该函数返回一个包含有匹配文件 / 目录的数组。如果出错返回 false。
<?php //获取目录所有文件并将结果保存到数组 foreach(glob("目录名/*") as $d){ $tmp=explode('.',$d); $k=end($tmp); //如果是文件,并且后缀名为jpg png的文件 if(is_file($d)&&in_array($k,array('jpg','png'))){ $files[]=str_replace('******目录名/','',$d); } } ?>
循环过程中因为我只想得到图片名称,所以我把前面的目录替换为空。
第三步:
列出所有的图片后就该把图片文件名插入数据库了。
写个循环就可以了啊。
首先,用SELECT。。。。。。。。查出系统会员,然后计算出系统会员的个数,
<?php //查出系统会员 $member= DB::query(Database::SELECT, " SELECT * FROM 会员表名 WHERE 是否为系统会员 =1; ") ->execute() ->as_array(); ?>
然后再循环插入数据库:
<?php for($i=0;$i<count($files);$i++){ $data = array( '图片字段' => $files[$i], ); DB::update('会员表') ->set($data) ->where('系统会员ID', '=', $member[$i]['系统会员ID']) ->execute(); } ?>
OK。就这样就搞定了。

In PowerPoint, it is a common technique to display pictures one by one, which can be achieved by setting animation effects. This guide details the steps to implement this technique, including basic setup, image insertion, adding animation, and adjusting animation order and timing. Additionally, advanced settings and adjustments are provided, such as using triggers, adjusting animation speed and order, and previewing animation effects. By following these steps and tips, users can easily set up pictures to appear one after another in PowerPoint, thereby enhancing the visual impact of the presentation and grabbing the attention of the audience.

Go language is an efficient, concise and easy-to-learn programming language. It is favored by developers because of its advantages in concurrent programming and network programming. In actual development, database operations are an indispensable part. This article will introduce how to use Go language to implement database addition, deletion, modification and query operations. In Go language, we usually use third-party libraries to operate databases, such as commonly used sql packages, gorm, etc. Here we take the sql package as an example to introduce how to implement the addition, deletion, modification and query operations of the database. Assume we are using a MySQL database.

How to use MySQLi to establish a database connection in PHP: Include MySQLi extension (require_once) Create connection function (functionconnect_to_db) Call connection function ($conn=connect_to_db()) Execute query ($result=$conn->query()) Close connection ( $conn->close())

1. Open the slide and insert all pictures. 2. Click Picture Tools | Format | Picture Layout and select the hexagon cluster. 3. Then type the text content in the text box on the left. 4. Select the image and the system will activate the SmartArt tool menu. 5. Click the Design menu, then find the SmartArt style toolset, and then click the Change Color button. 6. Select the color you want in the pop-up theme color drop-down menu. 7. The effect after the design is completed is as shown in the figure below:

Hibernate polymorphic mapping can map inherited classes to the database and provides the following mapping types: joined-subclass: Create a separate table for the subclass, including all columns of the parent class. table-per-class: Create a separate table for subclasses, containing only subclass-specific columns. union-subclass: similar to joined-subclass, but the parent class table unions all subclass columns.

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

HTML cannot read the database directly, but it can be achieved through JavaScript and AJAX. The steps include establishing a database connection, sending a query, processing the response, and updating the page. This article provides a practical example of using JavaScript, AJAX and PHP to read data from a MySQL database, showing how to dynamically display query results in an HTML page. This example uses XMLHttpRequest to establish a database connection, send a query and process the response, thereby filling data into page elements and realizing the function of HTML reading the database.

Analysis of the basic principles of the MySQL database management system MySQL is a commonly used relational database management system that uses structured query language (SQL) for data storage and management. This article will introduce the basic principles of the MySQL database management system, including database creation, data table design, data addition, deletion, modification, and other operations, and provide specific code examples. 1.
