DreamWeaver cms can access the database by: 1. Connect to the database, open the "./include/config.php" file, find the corresponding code segment and configure the database according to the situation; 2. Execute SQL query, the statement is "$sql = "SELECT * FROM `dede_addonsoft`"", where "$sql" is the query statement you want to execute; 3. After execution, you can use the "var_dump()" function, "print_r()" function, etc. to output The result is enough.
The operating system of this tutorial: Windows 10 system, DedeCMS version 5.7.109, Dell G3 computer.
Dreamweaver CMS can access the database through its own `MySQL database manager`, and can be implemented through code.
The specific steps are as follows:
1. Connect to the database
First open the `./include/config.php` file and find the following code segment:
/* 数据库配置 */ define('DB_HOST', 'localhost'); // 服务器地址 define('DB_NAME', 'yourdbname'); // 数据库名 define('DB_USER', 'yourdbusername'); // 用户名 define('DB_PASSWORD', 'yourdbpassword'); // 密码 define('DB_PREFIX', 'dede_'); // 表名前缀
Fill in the above constants according to your own situation.
2. Execute SQL query
Insert the following code where you need to execute the SQL query:
$dsql = new DedeSql(false,false); // 初始化数据库类
$sql = "SELECT * FROM `dede_addonsoft`"; // 查询语句
$dsql->SetQuery($sql); // 设置查询语句
while($row = $dsql->GetArray()){
// 输出结果
}Among them, `$sql` is the query statement you want to execute .
3. Check the execution results
After the execution is completed, you can use the `var_dump()` function, `print_r()` function, etc. to output the results, for example:
while($row = $dsql->GetArray()){
var_dump($row);
}This An array will be output containing all rows and columns of the query results.
The above is a simple example, you can modify the code according to your own needs to adapt to more complex queries and operations.
