If you want to update order status & state programmaticaly, you try this
$order->setStatus(Mage_Sales_Model_Order::STATE_COMPLETE); $order->setState(Mage_Sales_Model_Order::STATE_COMPLETE);
And you get this error :
The Order state 'complete' must not be set manually.
To fix it, use this :
$order->addStatusToHistory(Mage_Sales_Model_Order::STATE_COMPLETE, "Comments");
$order->setData('state', Mage_Sales_Model_Order::STATE_COMPLETE);

You need to define a constant containing an array but the code below doesn’t work ?
define('FILTER_ECOLE', array('price, categorie, niveau'));
You get an error :
Notice: Use of undefined constant FILTER_ECOLE - assumed 'FILTER_ECOLE' in /home/www/adin/app/code/local/Adin/Catalog/Block/Nav/Catalog/Layer/View/Sidebar.php on line 50
To define an use a constant containing an array you can simply serialize it :
#define
define('FILTER_ECOLE', serialize(array('price, categorie, niveau')));
#use
$filter = unserialize(FILTER_ECOLE);
Here, how to add new action in grid like ‘Edit’ link at admin grid.
On this example, we will add a “schedule” action in product admin grid.
We will overrite this class /app/code/core/Mage/Adminhtml/Block/Catalog/Product/Grid.php.
Declare the rewrite class on the /app/code/local/Adin/Catalog/etc/config.xml
and add
<global>
<blocks>
<adminhtml>
<rewrite>
<catalog_product_grid>Adin_Catalog_Block_Adminhtml_Catalog_Product_Grid</catalog_product_grid>
</rewrite>
</adminhtml>
</blocks>
</global>
Then create your rewritted class /app/code/local/Adin/Catalog/Block/Adminhtml/Catalog/Product/Grid.php.
<?php
class Adin_Catalog_Block_Adminhtml_Catalog_Product_Grid extends Mage_Adminhtml_Block_Catalog_Product_Grid {
}
?>
Now, rewrite the _prepareColumns() function, find the ‘action’ column an add an entry in the actions array
$this->addColumn('action',
array(
'header' => Mage::helper('catalog')->__('Action'),
'width' => '50px',
'type' => 'action',
'getter' => 'getId',
'actions' => array(
array(
'caption' => Mage::helper('catalog')->__('Edit'),
'url' => array(
'base'=>'*/*/edit',
'params'=>array('store'=>$this->getRequest()->getParam('store'))
),
'field' => 'id'
),
array(
'caption' => Mage::helper('catalog')->__('Schedule'),
'url' => array(
'base'=>'*/*/schedule',
'params'=>array('store'=>$this->getRequest()->getParam('store'))
),
'field' => 'id'
),
),
'filter' => false,
'sortable' => false,
'index' => 'stores',
));
In our example, we just add this part
array(
'caption' => Mage::helper('catalog')->__('Schedule'),
'url' => array(
'base'=>'*/*/schedule',
'params'=>array('store'=>$this->getRequest()->getParam('store'))
),
'field' => 'id'
),
One last thing, at the end of the _prepareColumns function, change
return parent::_prepareColumns();
by
return Mage_Adminhtml_Block_Widget_Grid::_prepareColumns();
While your coding session, you encounter this error :
Use of undefined constant MCRYPT_BLOWFISH - assumed 'MCRYPT_BLOWFISH
You think, easy, a module should be missing on my php
So you install it :
sudo apt-get install php5-mcrypt
And restart apache.
But it still doesn’t work. In phpinfo() it seems the module is not installed.
In fact with the new version of PHP, you still need to activate the module
php5enmod -s apache2 mcrypt
The restart apache and the module should work.
GnuPG is a great tool to encrypt texts and files and you can use it with PHP, only if you install it succesfully.
First, you will get this error : Fatal error: Class ‘gnupg’ not found in ….
OK the lib is not installed, do it with pecl
pecl install gnupg
But you will also have this error :
configure: error: Please reinstall the gpgme distribution ERROR: `/tmp/pear/temp/gnupg/configure' failed
You need to install the libgpgme too !!!
apt-get install libgpgme11-dev
Now retry to install gnupg
pecl install gnupg
It should be OK.
Don’t forget to modify your php.ini file to load the extension
extension=gnupg.so
And of course, restart your apache web server
/etc/init.d/apache2 restart
Since PHP 5.3.9 form are limited to 1000 fields by default.
To fix it, you can edit your php.ini file and modify this variable
max_input_vars = 4000
And don’t forget to restart apache.
You can also edit it in your .htaccess file
php_value max_input_vars 4000
Change it directly in your php file with this
ini_set('php_value max_input_vars', 4000);
won’t work.
But change this varible may not fix your issue.
If you have suhosin installed, you laso have to edit his configuration file (/etc/php5/apache2/conf.d/suhosin.ini)
suhosin.get.max_vars = 4000 suhosin.post.max_vars = 4000 suhosin.request.max_vars = 4000
To check your suhison configuration, use phpinfo() or in your php script
echo ini_get('suhosin.post.max_vars');
The easiest and safest way to check email address validity is to use the php embedded function filter_var() :
