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',
));
}
?>
