I think many cakephp programmer will get confuse when they want to save column/field on table with mysql function such as NOW(), CURDATE(), etc, We cannot use simple way of the saveField method or save method on model object.
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.

I found something strange on cakephp when i create form using FormHelper, a strange id appear on the action url. So i have this code on my view
<?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

Starting from wordpress 2.5 and above, you cannot remove generated meta tag wordpress version through your template. On prior version, it is simple by comment the line for showing wordpress version on your template.
<meta name="generator" content="WordPress <?php bloginfo('version'); ?>" />
WordPress 2.5 and above, the version is moved into the core of the wordpress. So it will automatically generate metatag generate, such as
<meta name="generator" content="WordPress 3.0" />
If you want to remove this generated line, there are some ways :
- Login to administration wordpress page, and then go to Appearance > Themes, And then Editor. Open functions.php, Add this line before the closing
?> tag
remove_action('wp_head', 'wp_generator');
- Or use this plugin. Install on plugins area.
If you run redirect function on cakephp 1.1, don’t forget to add exit() function after redirect sintax. This thing can make security hole that confusing you. The purpose of adding exit() function after redirect sintax is to avoid php running others code after redirect function.
$this->redirect('controller/action');
exit();
However cakephp 1.2 give you default exit after redirect. The complete sintax for redirect on cakephp 1.2 is
$this->redirect('controller/action', null, true);
which the third parameter define exit = true, means terminate the script. second parameter is for setting exit status, for example 404, etc. Defaultly you only need to write
$this->redirect('controller/action');

Cakephp has a good ways for handling table relationship model using AppModel association structure. It is easy to create and set relation between two or more tables on your database. Cakephp has setting for one to one, one to many, many to many relationship.
I would like to tell you about setting foreignKey for one to many relationship in cakephp that the master table doesn’t have foreignKey id. On your model, the relationship for one to many that set on child table would look like this
<?php
class CurrencyRate extends AppModel {
var $belongsTo = array('Currency' => array(
'className' => 'Currency',
'foreignKey' => 'currency_id',
));
}
?>

Cakephp have great routing capability, i was install wordpress blog on my main website root directory. And then i need to move my blog into new folder, i put it on /app/webroot/blog/ because i build new web application on root directory using cakephp.
I use rewriting rule for my wordpress blog. The rule is http://www.balistupa.com/year/month/slug/. I want to redirect into http://www.balistupa.com/blog/year/month/slug/. I don’t want to loose my blog visitors because the blog posting has good ranking on google.
So i do setting on app/config/routes.php and add this line
Router::connect(‘/:year/:month/:slug’, array(‘controller’ => ‘pages’, ‘action’ => ‘redirect_blog’), array(‘pass’ => array(‘year’, ‘month’, ‘slug’), ‘year’ => ‘[0-9]{4}’, ‘month’ => ‘[0-9]{2}’, ‘slug’ => ‘[A-Za-z0-9-]+’));
