However, now i am using cakephp framework. And if we need to put file or folder, it need to be put inside app/webroot folder. So if i need to install wordpress blog in http://www.balistupa.com/blog, i need to put the blog folder inside /app/webroot/.

The problem is about the url, with standard setting the blog would be redirected to http://www.balistupa.com/app/webroot/blog/ not to http://www.balistupa.com/blog/. This is not look good for visitor and also for seo. Because the folder structure is to deep.

After researching, i play with .htaccess setting to redirect /app/webroot/blog/ into /blog/ url. And the solution is very simple. So this is the step how i install wordpress blog inside cakephp framework.

1. upload wordpress files into /app/webroot/blog/ folder on server
2. setting /app/webroot/blog/wp-config.php with appropriate setting for database
3. and then install wordpress. On this step you will get directed to http://www.yourdomain.com/app/webroot/blog/install.php. Dont worried about the path, we can fix it easily
4. After installation finished, go to wordpress admin area at http://www.yourdomain.com/app/webroot/blog/wp-admin and then log in
5. Go to Settings > General. Change WordPress address (URL) and Site address (URL) into http://www.yourdomain.com/blog/ and then Save.
6. If using mod_rewrite for wordpress, Open /app/webroot/blog/.htaccess. Change into
   <IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /app/webroot/blog/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /app/webroot/blog/index.php [L]
</IfModule>
7. Open /.htaccess, Change its setting into
   RedirectMatch temp ^/blog/wp-admin$ http://www.yourdomain.com/blog/wp-admin/
RewriteRule blog$ /blog/ [L]
RewriteRule blog/wp-admin$ /blog/wp-admin/ [L]
RewriteRule ^$ app/webroot/ [L]
RewriteRule (.*) app/webroot/$1 [L]
8. Finished. Now you will have wordpress blog url at http://www.yourdomain.com/blog/

I notice that this setting also fix the problem user access http://www.yourdomain.com/blog without end /, and redirected into http://www.yourdomain.com/blog/.

So that is how we can redirecting http://www.yourdomain.com/app/webroot/blog/ into http://www.yourdomain.com/blog/ for installing Wordpress blog inside Cakephp Framework

First method is sleep using javascript loop. This is first method that come to my mind when emulate sleep method on javascript. We wait for the process by checking the time in the loop.

function wait(millisecond) {
var date = new Date();
var current_date = null;

do { current_date = new Date(); }
while(current_date-date < millisecond)
}

// do something
wait(1000); // wait 1000 millisecond
// do something

The disadvantage is this method blocking the whole browser process. So you need to think if you want to wait process for long time.

Second method is only valid on Firefox windows. I got this function on this thread. This is work as a threading process. So it does not block your whole browser process.

/**
* Netscape compatible WaitForDelay function.
* You can use it as an alternative to Thread.Sleep() in any major programming language
* that support it while JavaScript it self doesn't have any built-in function to do such a thing.
* parameters:
*  (Number) delay in millisecond
*/
function nsWaitForDelay(delay) {
/**
* Just uncomment this code if you're building an extention for Firefox.
* Since FF3, we'll have to ask for user permission to execute XPCOM objects.
*/
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");

// Get the current thread.
var thread = Components.classes["@mozilla.org/thread-manager;1"].getService(Components.interfaces.nsIThreadManager).currentThread;

// Create an inner property to be used later as a notifier.
this.delayed = true;

/* Call JavaScript setTimeout function
* to execute this.delayed = false
* after it finish.
*/
setTimeout("this.delayed = false;", delay);

/**
* Keep looping until this.delayed = false
*/
while (this.delayed) {
/**
* This code will not freeze your browser as it's documented in here:
* https://developer.mozilla.org/en/Code_snippets/Threads#Waiting_for_a_background_task_to_complete
*/
thread.processNextEvent(true);
}
}

Third method is asynchronous method, so it will not blocking the whole browser process.

function my_method() {
}
setTimeout("my_method()",1000);

you may also need to explore about setInterval and clearTimeout method for better use

There are two condition or event that you can intercept before it really happen, first when user close the browser windows and second is when browser windows will be closed without any way to abort it.

For first condition we can handle it using window.onbeforeunload event.

function closeHandler() {
return “Are you sure you want to close this page?”;
}

window.onbeforeunload = closeHandler;

And second condition when window will really closed, you can put on body tag or using window object

<body onUnload=”doUnload()”>

<script language=”Javascript”>
function doUnload() {
// do your code here
}
</script>

or using window object

function doUnload() {
// do your code here
}
window.onunload = doUnload;

I hope this article is help you on handling user when closing browser windows or page using javascript.

function isObject(obj) {
return obj.constructor == Object;
}

function print_object(object, level){
var tab = “”;
if(level > 0){
for(i = 0; i < level; i++) tab += “\t”;
}
var str = “”;
for(prop in object) {
if(!isObject(object[prop])) str += tab + prop + ” value :” + object[prop] + “\n”;
else str += tab + prop + “\n” + print_object(object[prop], level + 1);
}
return str;
}

and how to use this function is really simple approach

address = addresses.Placemark[0];
alert(print_object(address, 0));

in this scenario, i would like to print first placemark object return by geocoding function. Parameter level is use to make nice print view using tab character.

$this->Product->find(’all’, array(‘conditions’ => ‘1=1 GROUP BY Product.category_id’));

Now CakePhp have a clean sintak for GROUP BY by new additional paramater on find function. We can use ‘group’ to define GROUP BY on cakephp. For example

$this->Product->find(’all’, array(’fields’ => array(’Product.category_id’, ‘COUNT(Product.hotel_id) as total’), ‘group‘ => array(’Product.category_id’)));

How if we want to have HAVING sintak on query? i ussually use this solution for new cakephp

$this->Product->find(’all’, array(’fields’ => array(’Product.category_id’, ‘COUNT(Product.hotel_id) as total’), ‘group’ => array(’Product.category_id HAVING COUNT(Product.hotel_id) > 1′)));

To open an activity and wait for a result, we can use this sintax

Intent newIntent = new Intent(this.getApplicationContext(), ActivityClass2.class);
startActivityForResult(newIntent, 0);

ActivityClass2 is the class name of activity that we need to create and then open it from current activity. startActivityForResult is a method to run newActivity. Later we can have the result by add this function on current Activity

protected void onActivityResult(int requestCode, int resultCode, Intent data)

First to send a data or parameter to newActivity we can use this sintax

Bundle bundle = new Bundle();
bundle.putString(”param1″, “test”);

Intent newIntent = new Intent(this.getApplicationContext(), ActivityClass2.class);
newIntent.putExtras(bundle);
startActivityForResult(newIntent, 0);

On ActivityClass2, we can read this parameter using this sintax

Bundle bundle = this.getIntent().getExtras();
String param1 = bundle.getString(”param1″);

be carefull to use param1, because it can be null if we didn’t set it.

So it is very easy to send or passing data or parameter between two activity in Android. One last thing is to return a value for startActivityForResult, we can add this line code to close ActivityClass2 and return focus to opener plus send data to opener activity.

Bundle bundle = new Bundle();
bundle.putString(”status”, “OK”);
Intent mIntent = new Intent();
mIntent.putExtras(bundle);
setResult(RESULT_OK, mIntent);
finish();

For example we have parent table Author and hasOne Post, we can set INNER JOIN relation by default on model class or in controller using bindModel. In this example the hasOne relation set on model class

<?php
class Author extends AppModel {
var $name = ‘Author’;
var $hasOne = array(’Post’=>array(’type’=>’INNER’));
}
?>

and running on controller

$this->Author->find(’all’);

cakephp will generate query for author table.

SELECT `Author`.`id`, `Author`.`name`, `Post`.`id`, `Post`.`post_id`, `Post`.`title` FROM `authors` AS `Author` INNER JOIN `posts` AS `Post` ON (`Post`.`post_id` = `Author`.`id`) WHERE 1 = 1

So places table will have id, name, categories fields. and categories table have id, name. We want to save category list into categories field on places table. The data will look like this ‘2,3,4,5,6,7,8′. A question will come to your mind about how to grab or find a matching id inside this categories, for example we want to show all place with category id 5.

We cannot use LIKE in this example because it cannot match perfectly on many digit number. So i found a solution that easy to do. The query to find all data inside mysql Array field is

SELECT * FROM places WHERE FIND_IN_SET(5, categories)

Another solution is by adding new table to save category list for place. But my solution look nice, right?

• write or code java source for android application
• good overview for your project inside project manager
• user friendly interface to create new android project
• compile and debugging is as easy as desktop application development
• nice java source code editor with high text editing functionality for developer
• setting emulator also easy with good overview using DDMS perspective
• run android application inside emulator with simple click

There are many more advantage using eclipse as your IDE for android. Believe me it makes you enjoy coding android with their nice interface and automatic process.

Installing eclipse for android

1. Install JRE or JDK, but i suggest you to install JDK as we will develop java application. Read last article about installing jdk for android.
2. Download Eclipse IDE for Java Developers at http://www.eclipse.org/downloads/. Its about 92 MB.
3. Extract the zip file into a folder for example D:\ANDROID after downloaded
4. at this step you will have D:\ANDROID\eclipse folder
5. run D:\ANDROID\eclipse\eclipse.exe. On first time you will asked for workspace directory. It is a directory where you want your android project to be stored. For now just create new folder WORKSPACE in D:\ANDROID
6. install android sdk, you can read on installing android sdk article.
7. Now you need to connect eclipse and android sdk
8. on eclipse GUI, select Windows > Preferences menu on top.
9. select android and then locate your SDK Location, on my machine is D:\ANDROID\android-sdk, and then click apply
10. on eclipse GUI, select Help > Software Updates. some eclipse version maybe different menu location or name
11. click Available software tabs and then click Add site
12. You can try use this Location : https://dl-ssl.google.com/android/eclipse/ or http://dl-ssl.google.com/android/eclipse/. and then click OK
13. check the checkbox before https://dl-ssl.google.com/android/eclipse/ or http://dl-ssl.google.com/android/eclipse/ and then click Finish
14. It will direct you to download interface, wait until finish
15. at the end you will need to run plugins installation, just follow the step on interface.

At this point you already have a ready IDE for creating android application. Have fun and keep reading on my article about using eclipse to create android application.

First of all you need a java library installed on your machine. It can be a JRE or JDK, but i suggest you to install JDK as we want to develop a java application on our machine.

Installing JDK for android

1. go to http://java.sun.com/javase/downloads/index.jsp
2. find Java SE Development (JDK) section. The latest JDK version at the moment is JDK 6 Update 14
3. Click on Download Button
4. Run the executable installation file after download finished

Note : you can use J2EE, but J2SE is enough for android.

Installing android SDK

1. download http://developer.android.com/sdk/1.5_r3/index.html based on your Operating System platform. In my machine i use Windows so i download android-sdk-windows-1.5_r3.zip
2. extract android-sdk-windows-1.5_r3.zip into a folder for example D:\android-sdk
3. add D:\android-sdk\tools into PATH environmental variables on your system. You can find it on Control Panels > Systems
4. please restart your computer

At this point you have an android sdk that installed on your machine. You are ready to use android sdk and run using their great android emulator. You can coding using your text editor and compile using JDK and then create Android Package using Android SDK and then run it using android emulator. But i suggest you to use eclipse because it is more easier to build android application using eclipse automatic process.
