CI natively only allows for  single parameter in custom callbacks. For an instance see the following code.


$this->form_validation->set_rules
('hstate', 'State', 'required|callback_suburb_check[' . $suburb . ']');

If you need to pass multiple parameters, you have several options. Obviously you can change CI behaviour by subclassing the core library. But in this tutorial we follow the less pain approach. That 's to access required parameters via POST variables within your custom callback function. They are still available in this scope.

There is another way using your PHP string handling knowledge. Just formatting all the parameters as single string and passing to the callback function.


$parameters = 'first_arg' . '||' . 'second_arg' . '||' . 'third_arg';
$this->form_validation->set_rules
('some_field', 'Some Field Name', 'callback__my_callback_function['.$parameters.']');

Then in your callback,


function _my_callback_function($field_value, $second_parameter){
    list($first_param, $second_param, $third_param) = split('||', $second_parameter);
    ...
}

In application/config/config.php
change:
$config['index_page']='index.php';
to
$config['index_page']='';

Create or modify .htaccess in project root with following content.

# Customized error messages.
ErrorDocument 404 /index.php
# Set the default handler.
DirectoryIndex index.php
# Various rewrite rules.

  RewriteEngine on
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ index.php?/$1 [L,QSA]

Also allow overriding .htaccess in your apache
/etc/apache2/sites-available/default
and edit the file & change to
AllowOverrideAll

and Restart Apache
sudo /etc/init.d/apache2 reload

or
sudo service apache2 reload

or
sudo /etc/init.d/httpd reload

PhoneGap
PhoneGap



1. First, check you’ve got Java and Ant installed – you’ll need those later:

sudo apt-get install default-jre
sudo apt-get install default-jdk
sudo apt-get install ant

2. Install npm
sudo apt-get install npm

3. Get the latest nodejs (by installing ‘n’ and running that):
sudo npm update npm -g
sudo npm install n -g
sudo n stable

4. Now install phonegap itself
sudo npm install -g phonegap

5. Download the Android sdk from http://developer.android.com/sdk/index.html, put it somewhere sensible and unpack it:
sudo mv ~/Downloads/adt-bundle-linux-x86-20130917.zip /opt/
cd /opt
sudo unzip adt-bundle-linux-x86-20130917.zip
sudo chmod -R 777 /opt/adt-bundle-linux-x86-20130917

6. Update PATH in ~/.bashrc to include the phonegap tools:
# Add android sdk
PATH=$PATH:/opt/adt-bundle-linux-x86-20130917/sdk/platform-tools:/opt/adt-bundle-linux-x86-20130917/sdk/tools

and then ‘source ~/.bashrc’ to make sure you’ve got the new path setup.

7. Create a phonegap app (I use a “projects” subdirectoy):
cd ~/projects
phonegap create my-app
cd my-app

8. Before you run the app, you’ll need to set up an emulator – run the android tool:
android

9. You may need to select a target (e.g. “Android 4.2.2 (API 17)”), and click the “Install 8 packages..” button (may need several clicks to accept all the licences)

Now setup and start an emulator – in the ‘android’ util, go to Tools -> Manage AVDs, go to the “Device Definitions”, select a device, and use the “Create AVD” button to create a new AVD. Then use the “Start..” button to start the AVD (it may take a surprisingly long time to start fully).

Run the app:
phonegap local run android

You should see the app compile and install on the emulator.

You can do the compile and install steps separately:
phonegap local build android
phonegap install android

10. Add plugins
Optional Step
phonegap local plugin add https://git-wip-us.apache.org/repos/asf/cordova-plugin-device.git
phonegap local plugin add https://git-wip-us.apache.org/repos/asf/cordova-plugin-media.git
