How to use

3.0 How to use

In the current version of our PHP SDK you can find only a few methods that you can implement in your code but they're so powerful that enable you to do pretty anything with MBurger CMS.

The SDK will return an array representing the response. By default methods that returns a list of objects are limited to 25 elements. See below for how to use pagination.

This SDK offers a fluent syntax composed of these parts:

1. Class instance

2. Parameters or Modifiers

3. Desired function

Below are reported all parameters/modifiers and functions with some examples.

For a complete list of all available parameters we remand to the official API documentation https://docs.mburger.cloud/api-docs-1.

3.1 Instantiate the SDK

To instantiate the SDK simply use:

$sdk = new MBurger();

or use the compact version (useful for chaining):

$response = (new MBurger())->getProject();

3.2 Functions

To obtain a project

$response = (new MBurger())->getProject();

To obtain a list of blocks

$response = (new MBurger())->getBlocks();

To obtain a specific block by id

$response = (new MBurger())->getBlock($block_id);

To obtain a list of sections

$response = (new MBurger())->getSections($block_id);

To obtain a specific section by id or slug

$response = (new MBurger())->getSection($block_id_or_slug);

3.3 Modifiers

Below a list of modifiers (or middle methods) useful to personalize the request.

3.3.1 Locale

To request a specific locale use the locale(string $locale) modifier. Example:

$response = (new MBurger())->locale($locale)->getProject();

If the requested locale is not present an automatic fallback will be done. If you want to force the fallback if the requested locale is not present or is empty use the forceLocaleFallback() modifier:

$response = (new MBurger())->forceLocaleFallback()->getBlock();

3.3.2 Pagination

To use pagination in functions that returns a list of items use the modifiers skip(int $skip) and take(int $take). Example:

$response = (new MBurger())->skip(5)->take(50)->getSections(100);

Defaults are 0 and 25. The response will include a meta field containing the info for pagination, like total items and actual index.

3.3.3 Including

To include relations on the response are available a set of convenience methods. This can be useful, for example, for obtaining in one request all the desired sections with the related elements.

NOTE: Not all methods are compatible with all functions. The SDK will throw an MBurgeInvalidRequestException exception. Check our API references for more info.

NOTE: loading a lot of relations in one request can have a negative impact on performances.

• include(array $include): generic method, you can pass an array of desired relations.

• includeBlocks(): it will include blocks. Available only on getProject().

• includeSections(): it will include sections. Available only on getBlocks() and getBlock().

• includeElements(): it will include elements. Available only on getSections() and getSection().

• includeStructure(): it will include block structure. Available only on getProject(), getBlocks() and getBlock().

• includeBeacons(): it will include beacons. Available only on getProject(), getSections() and getSection().

• includeContracts(): it will include blocks. Available only on getProject().

Example: get first 15 sections of block 100 with the related elements

$response = (new MBurger())->take(15)->includeElements()->getSections(100);

3.3.4 Sorting

To apply specific orders is available this method sortBy(string $value, string $direction = 'asc'). the first argument specify on which value do the sorting, and the second the direction. Example:

$response = (new MBurger())->sortBy('created_at', 'desc')->take(15)->getSections(100);

The default sorting in by id and ascending.

NOTE: this method is only available on functions that returns a list of items.

3.3.4 Filtering

To filter items are available a set of convenience methods.

NOTE: Not all methods are compatible with all functions. The SDK will throw an MBurgeInvalidRequestException exception. Check our API references for more info.

NOTE: these methods are only available on functions that returns a list of items.

• filterByIds(array $ids): it filters based an array on id with an exact match. Available only on getBlocks() and getSections().

• filterByRelation(int $block_id, int $section_id): it filters based on related sections. Available only on getSections().

• filterByValue(array $values, string $element_name = null): it filters based on array of values. Specifying the second parameter element_name the filtering in done only on elements the match the name. Available only on getSections().

• filterByTitle(string $title): it filters based on title. Available only on getBlocks().

• filterByGeofence(float $latNE, float $latSW, float $lngNE, float $lngSW): it filters based on geofence rectangle. Available only on getSections().

3.3.5 Distance

If you have sections with elements of type address (which automatically contains coordinates) you can obtain your distance from the "section" (like a POI) with the method istance(float $latitude, float $longitude) by providing your coordinates. Example:

$response = (new MBurger())->distance(22.231232, 16.325322)->getSections(100);

NOTE: this method is only available on functions getSections().

3.3.6 Slug

Normally a section is retrieved by id or slug. MBurger tries to infer which method to use based on the type of the parameter: if it's numeric it will use the id, if it's a string it will use the slug. Is possible to force using the slug with the following method forceSlug(). Example:

$response = (new MBurger())->locale('en')->forceSlug()->getSection('321287');

NOTE: this method is only available on functions getSection().

3.4 Errors

MBurger SDK use an exception based error system, in case of error it will throw an exception with a descritive message.

3.5 Cache

Every function contains a method cache(int $cache_ttl = 0) to automatically cache the response. The TTL is in seconds. Example:

$response = (new MBurger())->cache(300)->getSections(100);

3.6 Transformers

There are utility methods useful to transform the response in a more usable format.

To transform blocks use transformBlocks($blocks). Example:

$blocks = (new MBurger())->getBlocks();
$data = MBurger::transformBlocks($blocks);
