How to clear Prestashop cache or recompile manually when modification do not see

Some people face problems when they are trying to update or modify their Prestashop. They update files, install modules, but these actions are not visible in Prestashop fronend. This problem often occurs in new Prestashop version – 1.4, because Prestashop 1.4 uses new cache system , now caching with “Smarty” and “Memcached”.

When you modify your Prestashop, you can disable cache in admin panel: Preferences > Performance

• Smarty block – Cache: disabled
• Caching block – Use cache: disabled

Delete cache manually, clean up this folder:

• Prestashop root folder/tools/smarty/cache
• Prestashop root folder/tools/smarty/compile

If you use smarty v2, clean up this folder:

• Prestashop root folder/tools/smarty_v2/cache
• Prestashop root folder/tools/smarty_v2/compile

Prestashop 1.5.x:

• Prestashop root folder cache/smarty/cache
• Prestashop root folder cache/smarty/compile

When you add Prestashop in your business, it is strongly recommended not to delete cache files and turn on all cache, because then your shop will work much faster.

How to create module in magento

In this blog post, we will learn how to start magento module development and basic files required setup a module.

Before starting with the module we need to first decide the name of the module, because after creating a module it’s very difficult to change the name of the module.

You can download module Creator Download

Extract this and paste moduleCreator to your xampp or wamp and open moduleCreator. 

e.g  'http://localhost/moduleCreator/'

your module creator looks like this

- In namespace enter your module namespace like your company name etc(required).

- In module field enter your module name(required).

- Others are optional, you can skip them. 

- Click on create button.

- Next step is copy all files created by module creator to your magento installation.

- Go to your xampp or wamp and open moduleCreator .

- Open new >> app >> code >> local >> 'Yourmodule' copy this and paste it to your magento installation in same directory.

- Open new >> app >> design >> adminhtml >> default >> default >> layout and copy your module xml file to your magento in same directory.

- Open new >> app >> design >> frontend >> default >> default >> layout and copy your module xml file and paste in your magento in app >> design >> frontend >> default >> 'Yourtheme' >> layout.

- Open new >> app >> design >> frontend >> default >> default >> template and copy your module template folder and paste in your magento in  app >> design >> frontend >> default >> 'Yourtheme' >> template.

- Open new >> app >> etc >> modules and copy your module xml file and paste in your magento in same directory.

- Now open your magento site and clear your cache. You can see your newly created module in admin section.

• When creating controller files or block file, etc remember to be careful about case sensitivity of file names. Especially, when you upload your module to linux server the module may stop working, if file cases and class name have not been put in carefully.
• All class names should be case-sensitive as well. Basically, based on the class name, magento includes that file. So, if class name is not correct, the file is not found by magento.

How to show out of stock products in magento

If you want to show/display out of stock products in magento than follow this:

Magento has several criteria for determining if an item should be visible in the store, but one of these is not whether or not the item is in stock. Magento can manage your stock and will set your stock status to “Out of Stock” for you, but what if you want these out of stock items to be hidden from the store.. automatically? Also, in my case I do not want to “disable” the item because the inventory management system will then ignore it. Turns out this was much more difficult to figure out than I expected it to be but the end solution was quite simple.

A. Login to Magento back-end
B. Go to menu System >> Configuration.
C. Take inventory tab from the left panel
D. Set Display out of stock products to ‘Yes’ in Stock options tab in the right panel

E. Clear your cache and reindex your Index management.

That's it.

How to create new theme OR copy base theme to another theme in magento

If you want to Create new theme for your magento or you don't want to make any changes in your base theme than follow this easy steps:

• At the first stage we create folders for our new theme. We call it mytheme. Then we add a new folder with the name of our new theme.
• It is important to remember! Before changing .Phtml file, it must be copied from base (or default) themes to a new theme. When Magento detects one of the files in a new theme, it will ignore .phtml file from a base (or default) theme. Copy only those files that will be changed. It minimizes the number of errors during Magento upgrade.

Step1: Go to app/design/frontend/base/default and copy that all folders

Step2: Now go to app/design/frontend/default/mytheme and paste here. Make sure there is already default folder. You don't need to change anything in that default folder.
