Query Builder Database Wrapper for WordPress

== Description ==

A lightweight, expressive query builder for WordPress. NInjaDB use the same `$wbdp` instance and methods, It will help you to write $wpdb queries easily and expressively. At least PHP 5.3 is required.

It has some advanced features like:
 - Query Like Laravel Basic Queries
 - Where, orWhere methods
 - Search data in all the columns or specific columns
 - Easily Implement Pagination
 - use insert, update or delete methods expressively.

The syntax is quite similar to Laravel's query builder.

**Simple Query:**

The query below returns the row where id = 3, null if no rows.

    $row = ninjaDB('my_table')->find(3);

**Full Queries:**

    $query = ninjaDB('my_table')->where('post_author', '=', 1);  // for equal you can just use where('post_author, 1);
    // Get result as array of objects
    $query->get();


## Full Usage API


### Initiate
---
    // Select a table
    $query = ninjaDB()->table('post');  // post is the table name without prefix;

**OR You can pass your table name as an argument**

    // Select a table
    $query = ninjaDB('my_table');  // post is the table name without prefix;

## Query


### Get Easily
The query below returns the (first) row where id = 3, null if no rows.

    $row = ninjaDB('my_table')->find(3);

Access your row like, `echo $row->name`. If your field name is not `id` then pass the field name as second parameter `ninjaDB('my_table')->find(3, 'author_id');`.

The query below returns the all rows as array of objects where author_id = 3, null if no rows.

    $result = ninjaDB('my_table')->findAll('author_id', 3);

### Select

    $query = ninjaDB('my_table')->select('*');

#### Multiple Selects

    ->select(array('myfield1', 'myfield2', 'amyfield3'));
    
Using select method multiple times `select('a')->select('b')` will also select `a` and `b`. Can be useful if you want to do conditional selects (within a PHP `if`).



#### Get All
Return an array of objects.

    $query = ninjaDB('my_table')->where('author_id', 1);
    $result = $query->get();

You can loop through it like:

    foreach ($result as $row) {
        echo $row->name;
    }


#### Get First Row

    $query = ninjaDB('my_table')->where('author_id', 1);
    $row = $query->first();

Returns the first row, or null if there is no record. Using this method you can also make sure if a record exists. Access these like `echo $row->name`.


#### Get Rows Count, MAX, MIN, AVerage, SUM

    $query = ninjaDB('my_table')->where('author_id', 1);
    $count = $query->count();
    $max = $query->max('views'); // Where `views` is the column name and all these will return integer / float
    $min = $query->min('views');
    $avg = $query->avg('views');
    $avg = $query->avg('views');
    $sum = $query->sum('views');


### Where
Basic syntax is `(fieldname, operator, value)`, if you give two parameters then `=` operator is assumed. So `where('name', 'jewel')` and `where('name', '=', 'jewel')` is the same.


    ninjaDB('my_table')
        ->where('name', '=', 'jewel')
        ->whereNot('age', '>', 25)
        ->orWhere('description', 'LIKE', '%query%');



### whereIn

    ninjaDB('my_table')
        ->whereIn( 'id', array(1,2,3) ) 
        ->get();
        
### Limit and Offset

    ->limit(30);
    ->offset(10);

    // or you can use aliases
    ->take(30);
    ->skip(10);

### Order By

    ->orderBy('id', 'ASC');

### Insert

    $data = array(
        'name' => 'Jewel',
        'description' => 'Hello, There'
    );
    $insertId = ninjaDB('my_table')->insert($data);

`insert()` method returns the insert id. optionally you can pass $format of your data as `->insert($data, $format);` where `$format` is  an array of formats to be mapped to each of the value in $data

#### Batch Insert

    $data = array(
        array(
              'name' => 'Jewel',
            'description' => 'Hello, There'
        ),
        array(
            'name'        => 'Adre',
            'description' => 'Hello, I am Adre Astrian'
        ),
    );
    $insertIds = ninjaDB('my_table')->batch_insert($data);

In case of batch insert, it will return an array of insert ids.


### Update

    $data = array(
        'name' => 'Shahjahan Jewel',
        'description' => 'Hello, There'
    );
    
    ninjaDB('my_table')->where('id', 5)->update($data);

Will update the name field to `Shahjahan Jewel` and description field to `Hello, There` where `id = 5`.



### Delete

    ninjaDB('my_table')->where('id', '>', 5)->delete();

Will delete all the rows where id is greater than 5.
