/*
* Uploads an image and its thumbnail into $folderName/big and $folderName/small respectivley.
* the generated thumnail could either have the same aspect ratio as the uploaded image, or could
* be a zoomed and cropped version.
* Directions:
* In view where you upload the image, make sure your form creation is similar to the following
* create('FurnitureSet',array('type' => 'file')); ?>
*
* In view where you upload the image, make sure that you have a file input similar to the following
* file('Image/name1'); ?>
*
* In the controller, add the component to your components array
* var $components = array("Image");
*
* In your controller action (the parameters are expained below)
* $image_path = $this->Image->upload_image_and_thumbnail($this->data,"name1",573,80,"sets",true);
* this returns the file name of the result image. You can store this file name in the database
*
* Note that your image will be stored in 2 locations:
* Image: /webroot/img/$folderName/big/$image_path
* Thumbnail: /webroot/img/$folderName/small/$image_path
*
* Finally in the view where you want to see the images
* image('sets/big/'.$furnitureSet['FurnitureSet']['image_path']);
* where "sets" is the folder name we saved our pictures in, and $furnitureSet['FurnitureSet']['image_path'] is the file name we stored in the database
* Parameters:
* $data: CakePHP data array from the form
* $datakey: key in the $data array. If you used file('Image/name1'); ?> in your view, then $datakey = name1
* $imgscale: the maximum width or height that you want your picture to be resized to
* $thumbscale: the maximum width or height that you want your thumbnail to be resized to
* $folderName: the name of the parent folder of the images. The images will be stored to /webroot/img/$folderName/big/ and /webroot/img/$folderName/small/
* $square: a boolean flag indicating whether you want square and zoom cropped thumbnails, or thumbnails with the same aspect ratio of the source image

How to use in controller?
Sample code is here:-
class UserAvatarsController extends AppController {
var $name = 'UserAvatars';
var $uses = array('UserAvatar','User'); //using modules
var $helpers = array('Html','Form','Javascript','Session');
var $paginate = array('limit' => 15); // Set records per page
var $components = array('Image'); // used Image components
function upload()
{
$this->user_session_check();
if (!empty($this->data))
{
$image_path = $this->Image->upload_image_and_thumbnail($this->data,"avatar",573,80,"avatar",true,'UserAvatar');
$this->data['UserAvatar']['avatar']=$image_path;
if ($this->UserAvatar->save($this->data))
{
$this->flash('Your avatar has been uploaded successfully',_ROOT.'avatar/upload',1);
}
}
}
}
?>

A solution for e-mail handling in CakePHP
The emailComponent (cake\libs\controller\components\email.php) is a way for you to using the same concepts of layouts and view ctp files to send formated messages as text, html or both. It supports sending via the built in mail functions of PHP, via smtp server or a debug mode where it writes the message out to a session flash message. It also supports file attachments.
Implements it in three easy Steps
1. Controller (STEP 1)
In your controller you need to add the component to your $components array or add a $components array to your controller like:
1. <?php
2. var $components = array('Email');
3. ?>
In this example we will set up a private method to handle sending the email messages to a user identified by an $id. In our controller (let's use the User controller in this example)
1. <?php
2. function _sendNewUserMail($id) {
3. $User = $this->User->read(null,$id);
4. $this->Email->to = $User['User']['email'];
5. $this->Email->bcc = array('anuragtrivediphp@gmail.com');
6. $this->Email->subject = 'Welcome to cakePHP email handling functionally';
7. $this->Email->replyTo = 'anuragtrivediphp @ gmail.com';
8. $this->Email->from = Anurag Blog';
9. $this->Email->template = ‘contact'; // note no '.ctp'
10. //Send as 'html', 'text' or 'both' (default is 'text')
11. $this->Email->sendAs = 'both'; // because we like to send pretty mail
12. //Set view variables as normal
13. $this->set('User', $User);
14. //Do not pass any args to send()
15. $this->Email->send();
16. }
17. ?>
You have sent a message; you could call this from another method like
1. $this->_sendNewUserMail( $this->User->id );
2. Setting up the Layouts (Step 2)
To use both text and html mailing message you need to create layout files for them, just like in setting up your default layouts for the display of your views in a browser, you need to set up default layouts for your email messages. In the app/views/layouts/ directory you need to set up (at a minimum) the following structure
email/
html/
default.ctp
text/
default.ctp
These are the files that hold the layout templates for your default messages. Some example content is below
email/text/default.ctp
1. <?php echo $content_for_layout; ?>
email/html/default.ctp
1. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
2. <html>
3. <body>
4. <?php echo $content_for_layout; ?>
5. </body>
6. </html>
3. Setup an email element for the message body
(Step 3)
In the app/views/elements/email/ directory you need to set up folders for text and html unless you plan to just send one or the other. In each of these folders you need to create templates for both types of messages referring to the content that you send to the view either by using $this->set() or using the $contents parameter of the send() method. Some simple examples are shown below. For this example we will call the templates
contact.ctp
1.Dear <?php echo $User['first']. ' ' . $User['last'] ?>,
In html
<p>Dear <?php echo $User['first']. ' ' . $User['last'] ?>,< br />
Thank you for your interest.</p>

1)Rewriting product.php?id=12 to product-12.html
It is a simple redirection in which .php extension is hidden from the browser’s address bar and dynamic url (containing “?” character) is converted into a static URL.
RewriteEngine on
RewriteRule ^product-([0-9]+)\.html$ product.php?id=$1
2) Rewriting product.php?id=12 to product/ipod-nano/12.html
SEO expert always suggest to display the main keyword in the URL. In the following URL rewriting technique you can display the name of the product in URL.
RewriteEngine on
RewriteRule ^product/([a-zA-Z0-9_-]+)/([0-9]+)\.html$ product.php?id=$2
3) Redirecting non www URL to www URL
If you type yahoo.com in browser it will be redirected to www.yahoo.com. If you want to do same with your website then put the following code to .htaccess file. What is benefit of this kind of redirection?? Please check the post about SEO friendly redirect (301) redirect in php and .htaccess.
RewriteEngine On
RewriteCond %{HTTP_HOST} ^optimaxwebsolutions\.com$
RewriteRule (.*) http://www.optimaxwebsolutions.com/$1 [R=301,L]
4) Rewriting yoursite.com/user.php?username=xyz to yoursite.com/xyz
Have you checked zorpia.com.If you type http://zorpia.com/roshanbh233 in browser you can see my profile over there. If you want to do the same kind of redirection i.e http://yoursite.com/xyz to http://yoursite.com/user.php?username=xyz then you can add the following code to the .htaccess file.
RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)$ user.php?username=$1
RewriteRule ^([a-zA-Z0-9_-]+)/$ user.php?username=$1
5) Redirecting the domain to a new subfolder of inside public_html.
Suppose the you’ve redeveloped your site and all the new development reside inside the “new” folder of inside root folder.Then the new development of the website can be accessed like “test.com/new”. Now moving these files to the root folder can be a hectic process so you can create the following code inside the .htaccess file and place it under the root folder of the website. In result, www.test.com point out to the files inside “new” folder.
RewriteEngine On
RewriteCond %{HTTP_HOST} ^test\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.test\.com$
RewriteCond %{REQUEST_URI} !^/new/
RewriteRule (.*) /new/$1
It is a simple redirection in which .php extension is hidden from the browser’s address bar and dynamic url (containing “?” character) is converted into a static URL.
RewriteEngine on
RewriteRule ^product-([0-9]+)\.html$ product.php?id=$1
2) Rewriting product.php?id=12 to product/ipod-nano/12.html

Internationalizing Your Cakephp Application(support multiple languages cakephp)
For some developers, allowing a website to support multiple languages is essential. Luckily cakePHP 1.2 has the foundations available to make this possible.
I certainly hope after using this guide you can quickly and easily implement multiple languages in your cake app without needing to skip around the place. If I fall short of this and you have suggestions, leave a comment.
Once you complete this tutorial your site will be able to:
1. display multiple languages
2. allow users to switch languages
3. store language settings in cookies, so returning visitors don't need to re-select their preferred language
The sites that I build typically require 3 languages:
1. British English(eng)
2. Koren (kor)
3. Japanes (jap)
Step 1: Setup the directories and file for your messages
app/locale/eng/LC_MESSAGES/ default.po
app/locale/kor/LC_MESSAGES/ default.po
app/locale/jap/LC_MESSAGES/ default.po
Example Code of app/locale/eng/LC_MESSAGES/ default.op file.
msgid "home"
msgstr "Home"
msgid "about_us"
msgstr "About us"
msgid "membership_options"
msgstr "Membership Options"
msgid "our_lessons"
msgstr "Our lessons"
msgid "community"
msgstr "Community"
msgid "contact_us"
msgstr "Contact Us"
msgid "faqs"
msgstr "FAQ's"
Step 2: Write some strings to translate.(.ctp view file code sample)
Step 3: Change the default language
// config/bootstrap.php
define(DEFAULT_LANGUAGE, 'eng');
Step 4: Let users change the language
Component Class:
class P28nComponent extends Object {
var $components = array('Session', 'Cookie');
function startup() {
if (!$this->Session->check('Config.language')) {
$this->change(($this->Cookie->read('lang') ? $this->Cookie->read('lang') : DEFAULT_LANGUAGE));
}
}
function change($lang = null) {
if (!empty($lang)) {
$this->Session->write('Config.language', $lang);
$this->Cookie->write('lang', $lang, null, '+350 day');
}
}
}
?>
Controller Class:
class P28nController extends AppController {
var $name = 'P28n';
var $uses = null;
var $components = array('P28n');
function change($lang = null) {
$this->P28n->change($lang);
$this->redirect($this->referer(null, true));
}
function shuntRequest() {
$this->P28n->change($this->params['lang']);
$args = func_get_args();
$this->redirect("/" . implode("/", $args));
}
}
?>
Controller Class:
//app_controller.php
class AppController extends Controller {
var $components = array('P28n');
}
?>
The final piece of code, are some custom routes that need to be added to cake/app/config/routes.php
//route to switch locale
Router::connect('/lang/*', array('controller' => 'p28n', 'action' => 'change'));
//forgiving routes that allow users to change the lang of any page
Router::connect('/eng/*', array('controller' => "p28n",'action' => "shuntRequest",'lang' => 'eng'));
Router::connect('/jap/*', array('controller' => "p28n",'action' => "shuntRequest",'lang' => 'jap'));
Router::connect('/kor/*', array('controller' => "p28n",'action' => "shuntRequest",'lang' => 'kor'));
Step 6: Links to change language
I certainly hope after using this guide you can quickly and easily implement multiple languages in your cake app without needing to skip around the place. If I fall short of this and you have suggestions, leave a comment.

}
function shuntRequest() {

?>
Controller Class:
//app_controller.php
class AppController extends Controller {
var $components = array('P28n');
}
?>
The final piece of code, are some custom routes that need to be added to cake/app/config/routes.php
//route to switch locale
Router::connect('/lang/*', array('controller' => 'p28n', 'action' => 'change'));
//forgiving routes that allow users to change the lang of any page
Router::connect('/eng/*', array('controller' => "p28n",'action' => "shuntRequest",'lang' => 'eng'));
Router::connect('/jap/*', array('controller' => "p28n",'action' => "shuntRequest",'lang' => 'jap'));
Router::connect('/kor/*', array('controller' => "p28n",'action' => "shuntRequest",'lang' => 'kor'));

Image Upload and Resize Component for CakePHP 1.2
############## image.php #####################
create a components image in following given path
/app/controllers/components/image.php
/*
File: /app/controllers/components/image.php
*/
class ImageComponent extends Object
{
/*
* Uploads an image and its thumbnail into $folderName/big and $folderName/small respectivley.
* the generated thumnail could either have the same aspect ratio as the uploaded image, or could
* be a zoomed and cropped version.
* Directions:
* In view where you upload the image, make sure your form creation is similar to the following
* create('FurnitureSet',array('type' => 'file')); ?>
*
* In view where you upload the image, make sure that you have a file input similar to the following
* file('Image/name1'); ?>
*
* In the controller, add the component to your components array
* var $components = array("Image");
*
* In your controller action (the parameters are expained below)
* $image_path = $this->Image->upload_image_and_thumbnail($this->data,"name1",573,80,"sets",true);
* this returns the file name of the result image. You can store this file name in the database
*
* Note that your image will be stored in 2 locations:
* Image: /webroot/img/$folderName/big/$image_path
* Thumbnail: /webroot/img/$folderName/small/$image_path
*
* Finally in the view where you want to see the images
* image('sets/big/'.$furnitureSet['FurnitureSet']['image_path']);
* where "sets" is the folder name we saved our pictures in, and $furnitureSet['FurnitureSet']['image_path'] is the file name we stored in the database
* Parameters:
* $data: CakePHP data array from the form
* $datakey: key in the $data array. If you used file('Image/name1'); ?> in your view, then $datakey = name1
* $imgscale: the maximum width or height that you want your picture to be resized to
* $thumbscale: the maximum width or height that you want your thumbnail to be resized to
* $folderName: the name of the parent folder of the images. The images will be stored to /webroot/img/$folderName/big/ and /webroot/img/$folderName/small/
* $square: a boolean flag indicating whether you want square and zoom cropped thumbnails, or thumbnails with the same aspect ratio of the source image

A easy captcha component implentation into cakephp.
First save the code below into a file called captcha.php and put it in your controller components folder
Then very important create a folder called "fonts" in your files which is located in webroot/files/ copy the fonts you want to use inside that folder you can add as many fonts as you like and use only true type fonts but here is a link to the fonts i used. www.getkeywords.co.za/files/fonts.tar.gz

First in the controller you want to implement it into add the component then create a function called captcha and and in the following and on the form you want to protect where it checks if the data is empty just add "&& $this->Captcha->protect()". That will return a boolean back.

Then very important create a folder called "fonts" in your files which is located in webroot/files/ copy the fonts you want to use inside that folder you can add as many fonts as you like and use only true type fonts but here is a link to the fonts i used. www.getkeywords.co.za/files/fonts.tar.gz

You can set CakePHP Debug Level
CakePHP Debug Level:
Production Mode:
0: No error messages, errors, or warnings shown. Flash messages redirect.
Development Mode:
1: Errors and warnings shown, model caches refreshed, flash messages halted.
2: As in 1, but also with full debug messages and SQL output.
3: As in 2, but also with full controller dump.
Note:-
In production mode, flash messages redirect after a time interval.
In development mode, you need to click the flash message to continue.
In core.php file u will get this code:-
Configure::write('debug',2);
Production Mode:
0: No error messages, errors, or warnings shown. Flash messages redirect.

PHP date problem
useful URL for PHP date problem
PHP Date Generator
http://www.b2ben.com/php/phpdate.php
http://www.b2ben.com/php/phpdate.php
url rewriting
useful url rewriting examples using .htaccess
1)Rewriting product.php?id=12 to product-12.html
It is a simple redirection in which .php extension is hidden from the browser’s address bar and dynamic url (containing “?” character) is converted into a static URL.
RewriteEngine on
RewriteRule ^product-([0-9]+)\.html$ product.php?id=$1
2) Rewriting product.php?id=12 to product/ipod-nano/12.html
SEO expert always suggest to display the main keyword in the URL. In the following URL rewriting technique you can display the name of the product in URL.
RewriteEngine on
RewriteRule ^product/([a-zA-Z0-9_-]+)/([0-9]+)\.html$ product.php?id=$2
3) Rewriting yoursite.com/user.php?username=xyz to yoursite.com/xyz
Have you checked zorpia.com.If you type http://zorpia.com/roshanbh233 in browser you can see my profile over there. If you want to do the same kind of redirection i.e http://yoursite.com/xyz to http://yoursite.com/user.php?username=xyz then you can add the following code to the .htaccess file.
RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)$ user.php?username=$1
RewriteRule ^([a-zA-Z0-9_-]+)/$ user.php?username=$1
4) Redirecting the domain to a new subfolder of inside public_html.
Suppose the you’ve redeveloped your site and all the new development reside inside the “new” folder of inside root folder.Then the new development of the website can be accessed like “test.com/new”. Now moving these files to the root folder can be a hectic process so you can create the following code inside the .htaccess file and place it under the root folder of the website. In result, www.test.com point out to the files inside “new” folder.
RewriteEngine On
RewriteCond %{HTTP_HOST} ^test\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.test\.com$
RewriteCond %{REQUEST_URI} !^/new/
RewriteRule (.*) /new/$1
It is a simple redirection in which .php extension is hidden from the browser’s address bar and dynamic url (containing “?” character) is converted into a static URL.
RewriteEngine on
RewriteRule ^product-([0-9]+)\.html$ product.php?id=$1
2) Rewriting product.php?id=12 to product/ipod-nano/12.html
SEO expert always suggest to display the main keyword in the URL. In the following URL rewriting technique you can display the name of the product in URL.
RewriteEngine on
RewriteRule ^product/([a-zA-Z0-9_-]+)/([0-9]+)\.html
3) Rewriting yoursite.com/user.php?username=xyz to yoursite.com/xyz
Have you checked zorpia.com.If you type http://zorpia.com/roshanbh233 in browser you can see my profile over there. If you want to do the same kind of redirection i.e http://yoursite.com/xyz to http://yoursite.com/user.php?username=x
RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)$ user.php?username=$1
RewriteRule ^([a-zA-Z0-9_-]+)/$ user.php?username=$1
4) Redirecting the domain to a new subfolder of inside public_html.
Suppose the you’ve redeveloped your site and all the new development reside inside the “new” folder of inside root folder.Then the new development of the website can be accessed like “test.com/new”. Now moving these files to the root folder can be a hectic process so you can create the following code inside the .htaccess file and place it under the root folder of the website. In result, www.test.com point out to the files inside “new” folder.
RewriteEngine On
RewriteCond %{HTTP_HOST} ^test\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.test\.com$
RewriteCond %{REQUEST_URI} !^/new/
RewriteRule (.*) /new/$1
