Cron Job to empty cache

[webbynz]

Hi,

 

I have a website where prices are updated for all products twice daily. What I'm looking to do is clear the cache of the front page, as it displays prices for some featured items and if the cache is not cleared, when you click one of the products, the price differs to that on the product page.

 

I assume it can be done, I just haven't a clue how and would really appreciate some help!

 

Many thanks

Ryan

You mean running the same function prestashop runs when you hit 'clear smarty cache' in the back office?

Hey, yeah that's exactly what I'm trying to automate.

 

Cheers

Try adding this to the file you call (be sure you include the config headers first)

 

Tools::clearSmartyCache();

Thanks for the information - I'm a complete newbie to cron jobs and have only ever set them up when the command has been provided. I don't actually understand what I need to do (sorry!).

 

Any chance you could provide me with some details, or point me to somewhere I could learn?

Many thanks in advance

Ryan

Sure, here is an article about them

But if you use cpanel, you can easily set them up using the builtin tools, where you basically only have to select the time period with dropdown menus, and link the script you want to call

Thanks a lot, I think I understand how to create via CPanel, as have done this before, it's more the script that I need the help with.

[NemoPS]

Oh, sorry!

 

In this case, before calling that method in your php file, be sure you include this

 

include(dirname(__FILE__).'config/config.inc.php');

include(dirname(__FILE__).'init.php');

 

 

BUT! depending on where you place your script, refer to the inclusions correctly Those are the settings to apply if your file sits in prestashop's root folder

Hi again, really thanks for your help but i'm not getting far......

 

Can you tell me what the entire contents of the .php file would be that I will need to create?

[NemoPS]

Sure

<?php


include(dirname(__FILE__).'config/config.inc.php');
include(dirname(__FILE__).'init.php');
Tools::clearSmartyCache();

Should work, but i haven't tested it.

[webbynz]

OK simple as that. Brilliant, thanks heaps!

Is it possible to create a Cron Task to automate this process? What should the URL look like?

And do you already have a sample URL. I would like to have a URL also

I'd also like to use the inbuilt Prestashop Cron Job module to automate the clearing of Smarty Cache....

Hi

 

This is an issue that is important to many of us.

I understand that you have to make a php file with the above content. Then what?

 

1.Where do we copy it on our site

2. How to make an absolute secure url reference to feed prestashops cron module?

 

Thank you

George

I would store it inside a module's folder, hardcode some kind of hashed token, then uset a GET to verify it's also passed when calling the cron url
