Smarty cache is great for server performance on production but is annoying on developpement.
Hopefully, you can enable or disable it.
On prestashop 1.3.x or less, you have to edit the root/config/smarty.config.php and edit these 2 lines
$smarty->caching = false; // to pass "true" when put into production $smarty->force_compile = true; // to pass "false" when put into production
On prestashop 1.4.x or more, you can do it directly on the backoffice, preference tab, performences subtab
Sometimes you need to make a script usig the prestashop framework. To do that, just add these 2 lines at the top of your script
include(dirname(__FILE__).'/../../config/config.inc.php'); include_once(_PS_ROOT_DIR_.'/init.php');
You want to see all values of an attribute, for debug purpose or something else ?
$attr_model = Mage::getModel('catalog/resource_eav_attribute');
$attr_model->load(959); // you can find the attribute_id on the eav_attribute table
$options = $attr_model->getSource()->getAllOptions(false);
foreach($options as $value)
{
print_r($value);
echo "<br />";
}
You will get something like that :
Array
(
[value] => 154
[label] => 2008
)
Array
(
[value] => 155
[label] => 2009
)
Array
(
[value] => 156
[label] => 2010
)
You just install a new instance of magento on a new server, for testing by example and you are unable to login. Password recovery send you a new password but it doesn’t work. This is probably a domain cookie issue.
After installing a new instance, you change in the database, table core_config_data, these 2 entry : web/unsecure/base_url and web/secure/base_url. Don’t forget to change this one too : web/cookie/cookie_domain and web/cookie/cookie_path
If you want to do some data loads in a Mysql DB regardless of insert or update statement you can use the INSERT … ON DUPLICATE KEY UPDATE request.
INSERT INTO test (firstname, lastname, skill)
VALUES
('Alan', 'Cox', 98),
('Robert', 'Love', 85),
('Linus', 'Torvalds', 24),
('Rusty', 'Russell', 79)
ON DUPLICATE KEY UPDATE
skill = VALUES(skill);
In this example, if the key is composed by firstname and lastname, when a duplicate key is detected, only the skill will be updated

You are using the fanstactic Gregwar/ImageBundle code to manipulate your images on Symfony2 and twig.
But instead of rendering your website, you get this error on your apache error log file
PHP Fatal error: Method Gregwar\\ImageBundle\\ImageHandler::__toString() must not throw an exception in /home/www/recette/app/cache/dev/classes.php on line 7426
or directly on your html genered code
<img src=" Fatal error: Method Gregwar\ImageBundle\ImageHandler::__toString() must not throw an exception in /home/www/recette/app/cache/dev/classes.php on line 7426
this issue may be a rights problem on your cache drectory. By default, gregwar cache directory is on your web so, launch this command
chmod 777 web/cache
This error may also occur if the file doesn’t exist, for a clean code, add
{% if file_exists('uploads/' ~ site.id ~ '.jpg') %}
{{ image(site.picture).resize(250, 50) }}
{% endif %}
or on twig code
{% if site.has_picture %}
{{ image(site.picture).resize(250 ,50) }}
{% endif %}
For more informations about file_exists, see here Symfony2 twig add new function file_exists
After installing Symfony 2 instead of viewing your website, you see this error message :
You need to enable either the SQLite3 or PDO_SQLite extension for the profiler to run properly.
It probably means you need to install the sqlite extension for php
apt-get install php5-sqlite
restart apache and that should to the tricks.
Imaginons qu’on ait une entrée de menu qui ressemble à ceci :
...
<menu>
<mon_module translate="title" module="adminhtml">
<children>
<mon_entree>
<title>Le titre de mon menu</title>
<action>maroute/adminhtml_index</action>
</mon_entree>
</children>
</mon_module>
</menu>
...
alors si on veut pouvoir gérer les droits d’accès via le menu permission alors il suffit d’ajouter
...
<menu>
<mon_menu translate="title" module="adminhtml">
<children>
<mon_entree>
<title>Le titre de mon entrée dans le menu mon_menu</title>
<action>maroute/adminhtml_index</action>
</mon_entree>
</children>
</mon_menu>
</menu>
<acl>
<resources>
<admin>
<children>
<mon_menu translate="title" module="mon_module">
<title>Le titre du menu qui va apparaître dans les permissions</title>
<sort_order>100</sort_order>
<children>
<mon_entree translate="title" module="mon_module">
<title>Le titre de mon entrée de menu qui va apparaître dans les permissions</title>
<sort_order>10</sort_order>
</mon_entree>
</children>
</mon_menu>
</children>
</admin>
</resources>
</acl>...
voilà c tout…
By default, for excel5 compatibility, writeexcel limit cells max size to 255 characters. You can increase it to 32767 by modifying the strmax parameter in the class.writeexcel_worksheet.inc.php line 116.
$strmax = 32767;
If you want to sort a collection on multiple field like that :
select * from toto order by field1 asc, field2 desc
You just have to have some setOrder() call on your collection like that :
$myCollection->getCollection()
->setOrder('field1', 'asc')
->setOrder('field2', 'desc')
;
That’s all folk…
