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。

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

To handle database connection errors in PHP, you can use the following steps: Use mysqli_connect_errno() to obtain the error code. Use mysqli_connect_error() to get the error message. By capturing and logging these error messages, database connection issues can be easily identified and resolved, ensuring the smooth running of your application.

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())

JSON data can be saved into a MySQL database by using the gjson library or the json.Unmarshal function. The gjson library provides convenience methods to parse JSON fields, and the json.Unmarshal function requires a target type pointer to unmarshal JSON data. Both methods require preparing SQL statements and performing insert operations to persist the data into the database.

Using the database callback function in Golang can achieve: executing custom code after the specified database operation is completed. Add custom behavior through separate functions without writing additional code. Callback functions are available for insert, update, delete, and query operations. You must use the sql.Exec, sql.QueryRow, or sql.Query function to use the callback function.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

Through the Go standard library database/sql package, you can connect to remote databases such as MySQL, PostgreSQL or SQLite: create a connection string containing database connection information. Use the sql.Open() function to open a database connection. Perform database operations such as SQL queries and insert operations. Use defer to close the database connection to release resources.

PHP database connection guide: MySQL: Install the MySQLi extension and create a connection (servername, username, password, dbname). PostgreSQL: Install the PgSQL extension and create a connection (host, dbname, user, password). Oracle: Install the OracleOCI8 extension and create a connection (servername, username, password). Practical case: Obtain MySQL data, PostgreSQL query, OracleOCI8 update record.
