Using the `create()` method provides chainability, which can add elegance and brevity to your code, e.g. `Player::create()->write()`. More importantly, however, it will look up the class in the [Injector](../extending/injector) so that the class can be overriden by [dependency injection](http://en.wikipedia.org/wiki/Dependency_injection).

Database columns and properties can be set as class properties on the object. The SilverStripe ORM handles the saving
of the values through a custom `__set()` method.
:::php
```php
$player->FirstName = "Sam";
$player->PlayerNumber = 07;
```
To save the `DataObject` to the database, use the `write()` method. The first time `write()` is called, an `ID` will be
set.
:::php
```php
$player->write();
```
For convenience, the `write()` method returns the record's ID. This is particularly useful when creating new records.
:::php
```php
$player = Player::create();
$id = $player->write();
```
## Querying Data
With the `Player` class defined we can query our data using the `ORM` or Object-Relational Model. The `ORM` provides
shortcuts and methods for fetching, sorting and filtering data from our database.
:::php
```php
$players = Player::get();
// returns a `DataList` containing all the `Player` objects.

echo $player->dbObject('LastEdited')->Ago();
// calls the `Ago` method on the `LastEdited` property.
```
The `ORM` uses a "fluent" syntax, where you specify a query by chaining together different methods. Two common methods
are `filter()` and `sort()`:
:::php
```php
$members = Player::get()->filter(array(
'FirstName' => 'Sam'
))->sort('Surname');
// returns a `DataList` containing all the `Player` records that have the `FirstName` of 'Sam'

## Looping over a list of objects
`get()` returns a `DataList` instance. You can loop over `DataList` instances in both PHP and templates.
:::php
```php
$players = Player::get();
foreach($players as $player) {
echo $player->FirstName;
}
```
Notice that we can step into the loop safely without having to check if `$players` exists. The `get()` call is robust, and will at worst return an empty `DataList` object. If you do want to check if the query returned any records, you can use the `exists()` method, e.g.
:::php
```php
$players = Player::get();
if($players->exists()) {
// do something here
}
```

There are a couple of ways of getting a single DataObject from the ORM. If you know the ID number of the object, you
can use `byID($id)`:
:::php
```php
$player = Player::get()->byID(5);
```
`get()` returns a [DataList](api:SilverStripe\ORM\DataList) instance. You can use operations on that to get back a single record.
:::php
```php
$players = Player::get();
$first = $players->first();
$last = $players->last();
```
## Sorting
If would like to sort the list by `FirstName` in a ascending way (from A to Z).
:::php
```php
// Sort can either be Ascending (ASC) or Descending (DESC)
$players = Player::get()->sort('FirstName', 'ASC');
// Ascending is implied
$players = Player::get()->sort('FirstName');
```
To reverse the sort
:::php
```php
$players = Player::get()->sort('FirstName', 'DESC');
// or..
$players = Player::get()->sort('FirstName', 'ASC')->reverse();
```
However you might have several entries with the same `FirstName` and would like to sort them by `FirstName` and
`LastName`
:::php
```php
$players = Players::get()->sort(array(
'FirstName' => 'ASC',
'LastName'=>'ASC'
));
```
You can also sort randomly. Using the `DB` class, you can get the random sort method per database type.
:::php
```php
$random = DB::get_conn()->random();
$players = Player::get()->sort($random)
```
## Filtering Results
The `filter()` method filters the list of objects that gets returned.
:::php
```php
$players = Player::get()->filter(array(
'FirstName' => 'Sam'
));
```
Each element of the array specifies a filter. You can specify as many filters as you like, and they **all** must be
true for the record to be included in the result.

'LastName' => 'Minnée',
));
// SELECT * FROM Player WHERE FirstName = 'Sam' AND LastName = 'Minnée'
```
There is also a shorthand way of getting Players with the FirstName of Sam.
:::php
```php
$players = Player::get()->filter('FirstName', 'Sam');
```
Or if you want to find both Sam and Sig.
:::php
```php
$players = Player::get()->filter(
'FirstName', array('Sam', 'Sig')
);
// SELECT * FROM Player WHERE FirstName IN ('Sam', 'Sig')
```
You can use [SearchFilters](searchfilters) to add additional behavior to your `filter` command rather than an
exact match.
:::php
```php
$players = Player::get()->filter(array(
'FirstName:StartsWith' => 'S'
'PlayerNumber:GreaterThan' => '10'

));

// Returns rows with any value (even null) other than Sam

If null values should be excluded, include the null in your check.
:::php
```php

// ... WHERE "FirstName" != 'Sam' AND "FirstName" IS NOT NULL
// Only returns non-null values for "FirstName" that aren't Sam.
// Strictly the IS NOT NULL isn't necessary, but is included for explicitness
```
It is also often useful to filter by all rows with either empty or null for a given field.

### Exclude
The `exclude()` method is the opposite to the filter in that it removes entries from a list.
:::php
```php
$players = Player::get()->exclude('FirstName', 'Sam');
// SELECT * FROM Player WHERE FirstName != 'Sam'
```
Remove both Sam and Sig..
:::php
```php
$players = Player::get()->exclude(
'FirstName', array('Sam','Sig')
);
```
`Exclude` follows the same pattern as filter, so for removing only Sam Minnée from the list:
:::php
```php
$players = Player::get()->exclude(array(
'FirstName' => 'Sam',
'Surname' => 'Minnée',
));
```
And removing Sig and Sam with that are either age 17 or 43.
:::php
```php
$players = Player::get()->exclude(array(
'FirstName' => array('Sam', 'Sig'),
'Age' => array(17, 43)
));
// SELECT * FROM Player WHERE ("FirstName" NOT IN ('Sam','Sig) OR "Age" NOT IN ('17', '43'));
```
You can use [SearchFilters](searchfilters) to add additional behavior to your `exclude` command.
:::php
```php
$players = Player::get()->exclude(array(
'FirstName:EndsWith' => 'S'
'PlayerNumber:LessThanOrEqual' => '10'
));
```
### Subtract
You can subtract entries from a [DataList](api:SilverStripe\ORM\DataList) by passing in another DataList to `subtract()`
:::php
```php
$sam = Player::get()->filter('FirstName', 'Sam');
$players = Player::get();
$noSams = $players->subtract($sam);
```
Though for the above example it would probably be easier to use `filter()` and `exclude()`. A better use case could be
when you want to find all the members that does not exist in a Group.
:::php
```php
// ... Finding all members that does not belong to $group.
$otherMembers = Member::get()->subtract($group->Members());
```
### Limit
You can limit the amount of records returned in a DataList by using the `limit()` method.
:::php
```php
$members = Member::get()->limit(5);
```
`limit()` accepts two arguments, the first being the amount of results you want returned, with an optional second
parameter to specify the offset, which allows you to tell the system where to start getting the results from. The
offset, if not provided as an argument, will default to 0.
:::php
```php
// Return 10 members with an offset of 4 (starting from the 5th result).
$members = Member::get()->sort('Surname')->limit(10, 4);
```

holding a contact form, which submits a message via email.

@ -22,29 +24,39 @@ Let's start by defining a new `ContactPage` page type:
return new Form($this, 'Form', $fields, $actions);
}
}
```
To create a form, we instanciate a `Form` object on a function on our page controller. We'll call this function `Form()`. You're free to choose this name, but it's standard practice to name the function `Form()` if there's only a single form on the page.
There's quite a bit in this function, so we'll step through one piece at a time.
:::php
```php
$fields = new FieldList(
new TextField('Name'),
new EmailField('Email'),
new TextareaField('Message')
);
```
First we create all the fields we want in the contact form, and put them inside a FieldList. You can find a list of form fields available on the [FormField](api:SilverStripe\Forms\FormField) page.
:::php
```php
$actions = FieldList(
new FormAction('submit', 'Submit')
);
```
We then create a [FieldList](api:SilverStripe\Forms\FieldList) of the form actions, or the buttons that submit the form. Here we add a single form action, with the name 'submit', and the label 'Submit'. We'll use the name of the form action later.
:::php
```php
return new Form($this, 'Form', $fields, $actions);
```
Finally we create the `Form` object and return it. The first argument is the controller that the form is on – this is almost always $this. The second argument is the name of the form – this has to be the same as the name of the function that creates the form, so we've used 'Form'. The third and fourth arguments are the fields and actions we created earlier.

The framework comes with a predefined validator called [RequiredFields](api:SilverStripe\Forms\RequiredFields), which performs the common task of making sure particular fields are filled out. Below is the code to add validation to a contact form:
:::php
```php
public function Form() {
// ...
$validator = new RequiredFields('Name', 'Message');
return new Form($this, 'Form', $fields, $actions, $validator);
}
```
We've created a RequiredFields object, passing the name of the fields we want to be required. The validator we have created is then passed as the fifth argument of the form constructor. If we now try to submit the form without filling out the required fields, JavaScript validation will kick in, and the user will be presented with a message about the missing fields. If the user has JavaScript disabled, PHP validation will kick in when the form is submitted, and the user will be redirected back to the Form with messages about their missing fields.

### Location
Element scoped shortcodes have a special ability to move the location they are inserted at to comply with HTML lexical
rules. Take for example this basic paragraph tag:
```ss
<p><a href="#">Head [figure,src="assets/a.jpg",caption="caption"] Tail</a></p>
```
When converted naively would become:
```ss
<p><a href="#">Head <figure><img src="assets/a.jpg" /><figcaption>caption</figcaption></figure> Tail</a></p>
```
However this is not valid HTML - P elements can not contain other block level elements.
To fix this you can specify a "location" attribute on a shortcode. When the location attribute is "left" or "right"
the inserted content will be moved to immediately before the block tag. The result is this:
```ss
<figure><img src="assets/a.jpg" /><figcaption>caption</figcaption></figure><p><a href="#">Head Tail</a></p>
```
When the location attribute is "leftAlone" or "center" then the DOM is split around the element. The result is this:
```ss

```

## Changing what a method returns
One major feature of an `Aspect` is the ability to modify what is returned from the client's call to the proxied method.
As seen in the above example, the `beforeCall` method modifies the `&$alternateReturn` variable, and returns `false`
after doing so.
```php
:::php
$alternateReturn = $this->writeDb->query($sql, $code);
return false;
```
By returning `false` from the `beforeCall()` method, the wrapping proxy class will_not_ call any additional `beforeCall`
handlers defined for the called method. Assigning the `$alternateReturn` variable also indicates to return that value

SilverStripe lets you customise the style of content in the CMS. This is done by setting up a CSS file called
`editor.css` in either your theme or in your `mysite` folder. This is set through
:::php
```php
HtmlEditorConfig::get('cms')->setOption('content_css', project() . '/css/editor.css');

If using this config option in `mysite/_config.php`, you will have to instead call:
:::php
```php
HtmlEditorConfig::get('cms')->setOption('content_css', project() . '/css/editor.css');
```
Any CSS classes within this file will be automatically added to the `WYSIWYG` editors 'style' dropdown. For instance, to
add the color 'red' as an option within the `WYSIWYG` add the following to the `editor.css`
:::css
```css

color: red;
}

In certain circumstances, you may want to use a different `session_name` cookie when using the `https` protocol for security purposes. To do this, you may set the `cookie_secure` parameter to `true` on your `config.yml`

This uses the session_name `SECSESSID` for `https` connections instead of the default `PHPSESSID`. Doing so adds an extra layer of security to your session cookie since you no longer share `http` and `https` sessions.
