What is DrupalGap?Mobile Application Development Kit for

Drupal Websites

DrupalGap Module is the connection between mobile applications and Drupal

websites

(c)drupalgap.org

Let's take a look, if it's true!

Support• Themes, modules

• Blocks

• Menus

• Pages

• Entities

• Fields

• Forms

• Views

• Messages

• Services

• Geolocation

• Other tools

• You don't need a Objective-C and Java developers

• For creating modules just need to write primitive JS code

• Need to know how work Services

• Need to know how to create custom Services endpoints and resources

To create powerful mobile application

How does PhoneGap work?

PhoneGap generates HTML, CSS and JavaScript and make application

iOS and Android mobile devices.

Apache Cordova provides access via JavaScript to device

features such as the Camera, GPS, File System, Contacts, Compass, etc.

How mobile application interacts with Drupal Core

Services FTW!!!:)

Drupal site Application

Drupal requirements

services, rest_server, taxonomy, views_datasource, views_json, drupalgap

Development environments Google Chrome and the Ripple Emulator extension

node.js cordova

Java SDK for Android or xCode for iOS

File structure

modules

themes

settings.js

Debugsettings.js:Drupal.settings.debug = true;

Logs in browser console:dpm(json_result);

window.localStorage.clear();

drupalgap_alert(Fatal error', { title: ‘Alert title', buttonName: 'Done', alertCallback: function() {} });

drupalgap_set_message('Oh no!', 'error');

Themedrupalgap.settings.theme = 'amazing'; drupalgap.settings.blocks.amazing = { header: { title: {} }, navigation: { user_menu_anonymous:{ roles:{ value:['anonymous user'], mode:'include' } }, user_menu_authenticated:{ roles:{ value:['authenticated user'], mode:'include' } } }, content: { messages: {}, main: {} }, footer: { } };

<div id="{:drupalgap_page_id:}" data-role="page"> {:header:} {:navigation:} {:content:} {:footer:} </div>

Need to add styles to index.html

page.tpl.html

Creating module with page callback• core_app (module folder)

• core_app.js (module file)

Drupal.modules.custom['core_app'] = {};

settings.js:

/** * Implements hook_menu(). */ function core_app_menu() { var items = {}; items['homepage'] = { title: 'DCDN Sandbox', page_callback: 'core_app_homepage' }; return items; } !function core_app_homepage() { var content = {}; content['homepage'] = { markup: 'some markup' }; return content; }

Creating Menu

drupalgap.settings.menus['homepage_menu'] = { links:[ {title:'News', path:'news'}, {title:'About', path:'node/1'}, {title:'Contact', path:'contact'}, {title:'Our team', path:'team'} ] };

settings.js:

Important: here might be only real paths, not aliases

Creating Blocks/** * Implements hook_block_info(). */ function core_app_block_info() { var blocks = { latest_news_block: { delta: 'latest_news_block', module: 'core_app' } }; return blocks; } !/** * Implements hook_block_view(). */ function core_app_block_view(delta) { var content = ''; if (delta == 'latest_news_block') { content = '<h2>Latest news</h2>'; content += 'Some content...'; } return content; }

Block visibilitydrupalgap.settings.blocks.amazing = { content: { homepage_menu: { pages:{ value:['homepage'], mode:'include' } }, latest_news_block: { pages:{ value:['homepage'], mode:'exclude' } }, users_block: { pages:{ value:['node/*', 'user/*'], mode:'include' }, roles:{ value:['authenticated user'], mode:'include' } }, }, }; !

Entitynode_load(1, { success: function(node) { } }); !node_save(node_array, { success: function(node) { } }); !node_delete(1, { success: function(node) { } });

By default available pages:

• node/%, node/%/edit

• user/%, user/%/edit

• taxonomy/term/%, taxonomy/term/%/edit

• comment/%, comment/%/edit

Using Views

Need to create page with JSON data document format (views_json module)

Displaying a View in mobile app

function core_team_menu() { var items = {}; items['team'] = { title: 'Our team', page_callback: 'core_team_page' } return items; }

/** * Implements hook_menu(). */ function core_app_menu() { var items = {}; items['vote-form'] = { title: 'Voting form', page_callback: 'drupalgap_get_form', page_arguments:['core_app_voting_form'] }; return items; }

/** * Form's validation function (optional). */ function core_app_voting_form_validate(form, form_state) { if (form_state.values.name == '') { drupalgap_form_set_error('name', 'Name is required field.'); } } !/** * Form's submit function. */ function core_app_voting_form_submit(form, form_state) { drupalgap_set_message('Thank you ' + form_state.values.name + '!'); drupalgap_goto('news'); }

Need additional functionality? You got it!1. Create custom services resource in Drupal module

hook_services_resources();

2. Create custom services call in DrupalGap moduleDrupal.services.call(options);

var output = ''; Drupal.services.call({ method: 'POST', path: 'news.json', data: args, success: function(result) { output = ''; $.each(result, function(i, node) { output += node.title; }); } });
