Firefox Geolocation Spoofing

Firefox Geolocater is a great for playing with fake geolocations. You can add geolocations as you wish and check how your Firefox browser take each of those locations as your current location. The plugin is very useful for developers who are building GIS web applications. You can download it here.

MySQL Check Time Duration Passed?

MySQL Time Duration

You may want to check whether a particular date has passed using start date, time duration and current date when the target date is not physically stored.

For clarity, consider a db table schema as follows.

+-----------+--------------------------+------------------+
| event_id | start_time               | duration_seconds |
+-----------+--------------------------+------------------+
| 005      |'2014-10-1 12:13:08'      | 86400            |
+-----------+--------------------------+------------------+

Here `duration_seconds` is stored using integers. If TIME is used, there 's a limit for 24 hrs.
If you want to get only adverts that have not expired, you will run a query like this.


SELECT * FROM  `events` WHERE TIME_TO_SEC(timediff(now(),start_time))<=`duration_seconds`;

Prevent HTTP Cache with PHP

HTTP Cache

HTTP Cache can be troublesome during development in some occasions specially in developing and testing web services, testing endpoints. We can use PHP headers to prevent and disable HTTP cache.


header("Content-Type: application/json");
header("Expires: 0");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");

Other than the above, there are other techniques of prevent browser caching.

Passing Multiple Parameters to Form Validation Custom Callbacks in Codeigniter

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);
    ...
}

How to remove index.php from CodeIgniter URL in Ubuntu

CodeIgniter

In application/config/config.php
change:

$config['index_page']='index.php';

$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

sudo service apache2 reload

sudo /etc/init.d/httpd reload

How to Install PhoneGap in Ubuntu

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

Import Excel Data into MySQL with PHP

PHPExcelReader.

To import Excel data, first you need to have a Excel reader. It should be accurate enough to interpret Excel data as expected. There 's a good old Excel reader.

Download PHPExcelReader.

In the downloaded archive, you only need Excel directory with files including oleread.inc and reader.php.

Just extract it where your web server can access.

Next place your excel file or just create one with some dummy data. Make sure this file is readble by the web server.

Finally create your php script to connect with database, read Excel file and insert data into db.


<?php

require_once 'Excel/reader.php';

$data = new Spreadsheet_Excel_Reader();

$data->setOutputEncoding('CP1251');

$data->read('a.xls');



$conn = mysql_connect("localhost","root","");

mysql_select_db("test",$conn);



for ($x = 2; $x <= count($data->sheets[0]["cells"]); $x++) {

$first = $data->sheets[0]["cells"][$x][1];

$middle = $data->sheets[0]["cells"][$x][2];

$last = $data->sheets[0]["cells"][$x][3];

$sql = "INSERT INTO mytable (First,Middle,Last)

VALUES ('$first','$middle','$last')";

echo $sql."\n";

mysql_query($sql);

}



?>
