# CommonModel Library for CodeIgniter 4
`CommonModel` is a versatile and reusable model for CodeIgniter 4, designed to simplify common database operations such as selecting, inserting, updating, and deleting records. This library provides methods that support common SQL features like JOINs, WHERE conditions, LIKE filters, ordering, and more.
## Features
- Multiple Database Connection Groups
- **Select records** with flexible conditions (`WHERE`, `OR WHERE`, `LIKE`)
- **Insert single or multiple records** into the database
- **Update and delete** records based on conditions
- **Join tables** for more complex queries
- Supports **ordering** and **pagination**
- Easy **counting** and **existence checks** for records
- Built-in support for **like** queries and **batch operations**
- Table and column management (add, remove, modify)
- Database creation and deletion

## Installation
To use `CommonModel` in your CodeIgniter 4 project, follow these steps:
1. Install with Composer:
```bash
composer require bertugfahriozer/ci4commonmodel
```
2. Load the model in your controller:
```php
use ci4commonmodel\Models\CommonModel;
class ExampleController extends BaseController
{
protected $commonModel;
public function __construct()
{
$this->commonModel = new CommonModel();
}
}
```
## Usage
### 1. Retrieving Records (`lists`)
Fetch records from a database table with flexible filters such as `WHERE`, `OR WHERE`, `LIKE`, `JOIN`, and ordering. Supports limit and pagination.
```php
// Simple usage
$users = $this->commonModel->lists('users', '*', ['status' => 1], 'id DESC', 10);
// Advanced usage with JOIN and LIKE
$joins = [
['table' => 'roles', 'cond' => 'users.role_id = roles.id', 'type' => 'left']
];
$like = ['name' => 'John'];
$users = $this->commonModel->lists('users', 'users.*, roles.name as role', ['status' => 1], 'users.id DESC', 10, 0, $like, [], $joins);
```
### 2. Inserting Records (`create`)
Insert a single record into the database and return the newly inserted ID.
```php
$data = [
'name' => 'John Doe',
'email' => 'john@example.com',
'status' => 1
];
$insertId = $this->commonModel->create('users', $data);
```
### 3. Batch Insert (`createMany`)
Insert multiple records at once.
```php
$data = [
['name' => 'Alice', 'email' => 'alice@example.com'],
['name' => 'Bob', 'email' => 'bob@example.com']
];
$this->commonModel->createMany('users', $data);
```
### 4. Updating Records (`edit`)
Update existing records by specifying the WHERE conditions and the new data.
```php
$data = ['status' => 2];
$where = ['id' => 1];
$this->commonModel->edit('users', $data, $where);
```
### 5. Deleting Records (`remove`)
Delete records from a table based on WHERE conditions.
```php
$where = ['id' => 1];
$this->commonModel->remove('users', $where);
```
### 6. Count Records (`count`)
Count the number of records that match a given condition.
```php
$where = ['status' => 1];
$count = $this->commonModel->count('users', $where);
```
### 7. Check Record Existence (`isHave`)
Check whether a record exists in a table with a specified condition.
```php
$where = ['id' => 1];
$isExist = $this->commonModel->isHave('users', $where);
```
### 8. Complex Queries (`research`)
Search records using LIKE queries and filtering by conditions.
```php
$like = ['name' => 'John'];
$where = ['status' => 1];
$results = $this->commonModel->research('users', $like, '*', $where);
```
### 9. Table and Database Management
#### Get Table List
```php
$tables = $this->commonModel->getTableList();
```
#### Create a New Table
```php
$fields = [
'id' => [
'type' => 'INT',
'constraint' => 5,
'unsigned' => true,
'auto_increment' => true,
],
'title' => [
'type' => 'VARCHAR',
'constraint' => '100',
'unique' => true,
]
];
$this->commonModel->newTable('blog', $fields);
```
#### Remove a Table
```php
$this->commonModel->removeTable('blog');
```
#### Add Column to Table
```php
$fields = [
'preferences' => ['type' => 'TEXT', 'after' => 'email'],
];
$this->commonModel->addColumnToTable('users', $fields);
```
#### Remove Column from Table
```php
$this->commonModel->removeColumnFromTable('users', ['preferences']);
```
#### Rename Table
```php
$this->commonModel->updateTableName('old_table', 'new_table');
```
#### Modify Column Info
```php
$fields = [
'old_name' => [
'name' => 'new_name',
'type' => 'TEXT',
'null' => false,
],
];
$this->commonModel->modifyColumnInfos('users', $fields);
```
#### Truncate Table
```php
$this->commonModel->emptyTableDatas('users');
```
#### Get Table Fields
```php
$fields = $this->commonModel->getTableFields('users');
```
#### Create a New Database
```php
$this->commonModel->newDatabase('new_db');
```
#### Remove a Database
```php
$this->commonModel->removeDatabase('old_db');
```
#### Drop Primary Key
```php
$this->commonModel->drpPrimaryKey('users');
```
#### Drop Key
```php
$this->commonModel->drpKey('users', 'my_key_name');
```
#### Drop Foreign Key
```php
$this->commonModel->drpForeignKey('orders', 'fk_orders_users');
```
## Troubleshooting: Multiple Database Connection Groups
When working with multiple database connections in CodeIgniter 4, defining them in the `.env` file is not sufficient on its own. Here's an example configuration in `.env`:
```ini
database.default.hostname=127.0.0.1
database.default.database=giritliadali
database.default.username=root
database.default.password=root
database.default.DBDriver=MySQLi
database.default.port=3306
database.secondDB.hostname=127.0.0.1
database.secondDB.database=giritliadali_bac
database.secondDB.username=root
database.secondDB.password=root
database.secondDB.DBDriver=MySQLi
database.secondDB.port=3306
```
Attempting to connect using:
```php
$this->db = \Config\Database::connect('secondDB');
```
Will result in the error:
```
"secondDB" is not a valid database connection group.
```
### Root Cause
CodeIgniter 4 does not auto-load database groups other than `default` from the `.env` file. You must explicitly define custom groups like `secondDB` in the `app/Config/Database.php` file.
### Solution
To fix this, add a new public array in your `app/Config/Database.php`:
```php
public array $secondDB = [
'DSN' => '',
'hostname' => 'localhost',
'username' => '',
'password' => '',
'database' => '',
'DBDriver' => 'MySQLi',
'DBPrefix' => '',
'pConnect' => false,
'DBDebug' => true,
'charset' => 'utf8mb4',
'DBCollat' => 'utf8mb4_general_ci',
'swapPre' => '',
'encrypt' => false,
'compress' => false,
'strictOn' => false,
'failover' => [],
'port' => 3306,
'numberNative' => false,
'foundRows' => false,
'dateFormat' => [
'date' => 'Y-m-d',
'datetime' => 'Y-m-d H:i:s',
'time' => 'H:i:s',
],
];
```
Once added, `\Config\Database::connect('secondDB')` will work properly.
