How to Error handling in cakephp 2 for PHP errors

In cakephp 2, error handling and exception handling are more better, the method cakeError now replaced by many built in Exception. So if you want to handle missing view etc, or any build in Exception, you need to check Exception handler setting. For PHP error that occured on view, we can handle it separately by using Error configuration.

To configure the error handling on php, open app/Config/core.php, find this line
Configure::write('Error', array(
'handler' => 'ErrorHandler::handleError',
'level' => E_ALL & ~E_DEPRECATED,
'trace' => true
));

handler is a callback function that handling the error on cakephp
level is built-in php error constants
trace true if you want to include trace message when displaying error message

If you want to handle the error in cakephp using your own class, create app/Lib/AppError.php
class AppError {
public static function handleError($code, $description, $file = null, $line = null, $context = null) {
echo 'There has been an error!';
}
}

and then add this line to app/Config/bootstrap.php to load the class
App::uses('AppError', 'Lib');

after that set app/Config/core.php
Configure::write('Error', array(
'handler' => 'AppError::handleError',
'level' => E_ALL & ~E_DEPRECATED,
'trace' => true
));


You can set default error layout by create new error layout template in app/View/Layouts/error.ctp, otherwise it will use default layout to display error message.

Handling Exception in cakephp 2

First you need to know several built in exception in cakephp 2, such as BadRequestException, ForbiddenException, NotFoundException, etc. You can find complete list on this link.

take a look at app/Config/core.php
Configure::write('Exception', array(
'handler' => 'ErrorHandler::handleException',
'renderer' => 'ExceptionRenderer',
'log' => true
));

You can create custom exception handler in app/Lib/AppExceptionHandler.php
class AppExceptionHandler {
public static function handle($error) {
echo 'Oh noes! ' . $error->getMessage();
// ...
}
// ...
}

and then add this line to app/Config/bootstrap.php
App::uses('AppExceptionHandler', 'Lib');

finally set your custom exception handler in app/Config/core.php
Configure::write('Exception.handler', 'AppExceptionHandler::handle');

There are several setting that you can use to maximize page load on prestashop, such as

1. Enable Smarty Cache File
   Set force compile to off will make page load are faster. Always Force compile will slow down the page load, only enable when you do template changes
2. Enabled CCC Setting
   Enable this to CSS, Javascript, and HTML without touching your template will improve your website performance. It decrease server load by combine all CSS files into one file. Also this setting compress the file so the filesize is smaller make it faster to load.
3. Enable Cache System
   This is important, if you dont have memcached feature on your hosting, just use File system cache. This caching system significantly improve page load speed.

Where you can find this setting to optimize prestashop? Just go to admin area, open menu Preferences > Performance

I will tell you how to edit seo parameter for title, keyword and description metatag for your homepage or your other pages except products and categories. Please follow this step

1. Go to admin area
2. Open Menu Preferences > SEO & URLs
3. And then edit index.php from the page list (url lists)
4. On next interface you will see input field for title, keyword and description metatag

Using this way, you could change seo parameter for another pages, just find on the list and then edit it.

So i explore about this problem and found there is a bug that when we enable cache system, the system will showing that error message. So i do this step

1. Go to Preferences > Performance, and turn off Caching. I also turn off smarty cache and force to compile.
2. And then i configure the modules, and never get that strange message anymore

I think the caching system need to fixed, because this caching system on prestashop often making strange behavior on the interface. If you find case like this just turn of caching system first. If everything has been setup then we can enable the caching system again for better performance on frontend

I use this procedure to get confirmation email order send to sales or admin email :

1. Install Maill Alerts by Prestashop Module, and then configure. Place target confirmation email address on Send to these e-mail addresses
2. Go to Employess > Contacts, set email for Customer Service
3. Go to Preferences > E-mail, set email to Customer Service

By using that procedure my prestashop now can send confirmation email order to sales or admin email.


ini_set('session.use_cookies', 0);
ini_set('session.use_only_cookies', 0);
ini_set('session.use_trans_sid', 1);
ini_set('session.name', 'PHPSESSID');
ini_set('url_rewriter.tags', 'a=href,area=href,frame=src,input=src,form=,fieldset=');


or add to php.ini

php_value session.use_cookies 0
php_value session.use_only_cookies 0
php_value session.use_trans_sid 1


And then for some reason also we need to disable PHPSESSID, for example to avoid duplicate content because off different session ID on the URL.

Here are how to disable PHPSESSID on URL

php_value session.use_only_cookies 1
php_value session.use_trans_sid 0


and to permanent redirect all previous link with PHPSESSID added to the url, use this php script


$actualurl= 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
$correcturl = 'http://www.balistupa.com/blog/';
if ($correcturl != $actualurl) {
header("HTTP/1.1 301 Moved Permanently");
header("Location: " . $correcturl);
exit();
}


And then please check on google all URL that have PHPSESSID, get list of them and then make a page that linking to all URL that you want to permanently redirect. It is a bit hard the get rid after indexing by google, but we need to do that to remove all duplicate content.

So i check to mysql manual and found interesting sintak, beside use AFTER column syntax, there is FIRST syntax. So the query is look like this

ALTER TABLE table_name ADD COLUMN `ID` INTEGER UNSIGNED NOT NULL AUTO_INCREMENT First,
ADD PRIMARY KEY (`ID`);

I hope this article can help you to add first column on existing table mysql database server.

This code will not save the data field into current date time on mysql.

$this->ModelName->saveField('date_field', 'NOW()');

or

$data['ModelName']['id'] = 1;
$data['ModelName']['date_field'] = 'NOW()';
$this->ModelName->save($data);

It will not work as you want. Because cakephp will ada quote on the value.

So the solution is by using DboSource class. Here are the code look like to save table column with current data time on mysql.

$this->ModelName->saveField('date_field', DboSource::expression('NOW()'));

or

$data['ModelName']['id'] = 1;
$data['ModelName']['date_field'] = DboSource::expression('NOW()');
$this->ModelName->save($data);

I hope this article help you for saving mysql function now, curdate, etc on cakephp model object.

I am using windows Vista, here are my step to solve debug certificate expired android problem :

1. Delete debug.keystore on C:\Users\{USER_PROFILE}\.android folder. For others operating system, you could check the path on eclipse. Please open menu Preferences – Android – Build – Default debug keystore.
2. On eclipse, Clean the projects ( Menu Projects > Clean ). You probably need to restart your eclipse.

I figure out this problem are because the certificate is expired. I wondering if this debug keystore is same as keystore that i create when i installing the Android SDK. I don’t know, but eclipse can generate it. It seem the certificate is expired in 365 days. I hope this article can help to solve this problem.

<?php echo $form->create('Evoucher', array('url' => array('controller' => 'gift_vouchers', 'action' => 'buy', $giftVoucher['GiftVoucher']['amount'])));?>

It is generated a form tag with strange id added on action url. Something like this

<form id="EvoucherBuyForm" method="post" action="/gift_vouchers/buy/2/20" accept-charset="utf-8">

After exploration, i found the problem was on the controller action for buy. I have set id for the data variable

$this->data['Evoucher']['id'] = 2;

So after taking out this line, i change it into

$this->Evoucher->id = 2;

And cakephp can generate correct action url for the form tag

<form id="EvoucherBuyForm" method="post" action="/gift_vouchers/buy/20" accept-charset="utf-8">

I hope this tutorial help you. Thanks for visiting our blog
