README

WordPress ActiveRecord implements the active record pattern to easily retrieve, update and delete rows of database tables without struggling with raw SQL query strings. The goal of this library is to provide a small but yet powerful ORM for the CMS WordPress, which should be easy to implement. Therefore it only consists of two classes: ActiveRecord and Query:

  • The ActiveRecord class maps rows to object instances and the columns to object properties.
  • The Query class provides a fluent interface to create sql queries.

Installation

composer require friedolinfoerder/wp-activerecord

Usage

You can use the library in your plugin or directly in your functions.php file. All you have to do is to require the ActiveRecord class and define your model classes (e.g. Slideshow):

// create a model class for the table {wp-prefix}slideshows 
class Slideshow extends \wp_activerecord\ActiveRecord {
    protected static $table_name = 'slideshows';
}

With this you can create new rows, update and save them like this:

// create new row
$slideshow = Slideshow::create([
    'title'        => 'Header slideshow',
    'slide_time'   => 3000,
    'slide_effect' => 'fade'
]);

// retrieve by id...
$slideshow = Slideshow::get(1);

// ... and update the row
$slideshow->title = 'New title';
$slideshow->slide_effect = 'slide';
$slideshow->save();

API

Class ActiveRecord

Static Properties

Property $casts

Cast row values to native types.

Example:
class Slideshow extends \wp_activerecord\ActiveRecord {
    protected static $casts = [
        'num_slides' => 'int',
        'duration' => 'float',
        'active' => 'boolean',
        'created_at' => 'datetime',
    ];
}

Static Methods

Table::delete_by_id(3);
Method get([$id])

Example:
$activeRecords = Table::get(); // all records
$activeRecord = Table::get(3); // one record by id
Method get_{type}_by_{column}($value [, $...])

Example:
$activeRecord = Table::get_one_by_title('WordPress');
$array = Table::get_by_name_or_title('wp-activerecord', 'WP');
$row = Table::get_row_by_name_and_title('wp', 'WP');
$var = Table::get_var_name_by_id(3);
Method get_table_name()

Get the table name

Example:
$table_name = Table::get_table_name();

Example:
$last_insert_id = Table::insert([
   'name'  => 'wp-activerecord',

   'name'  => 'ActiveRecord',
   'title' => 'Class ActiveRecord'
], [
   'name'  => 'Query',
   'title' => 'Class Query'
]]);
Method query()

Get a query instance

Example:
$query = Table::query();
Method update($column [, $value])

Shortcut method for creating a query instance and calling update on it

Example:
$query = Table::update('name', 'wp-activerecord-updated');
// or

   'name'  => 'wp-activerecord-updated',
   'title' => 'Updated WordPress ActiveRecord'
]);
Method wpdb()

Get the wpdb instance

Example:
$wpdb = Table::wpdb();

// use case:

  ->execute();

Delete the model

Example:
$activeRecord->delete();
Method save()

Save the model

$activeRecord->save();

Event methods

Called after saving the model

Example:
// in your derived class:
protected function save_post($isNew) {
    // do something with $this
}
