with json encode, module not validating in validator

[prestashop_newuser]

Hi,

 

I am doing a small module in Prestashop 1.5 . In that module I am getting some data from database as json format. For that I have done this

echo json_encode(array($result));

This one is working fine. But when I tried to upload the module to prestashop validator, it showed me the error like 

The use of function json_encode() is forbidden; use Tools::jsonEncode() instead

But when I tried

echo Tools::json_encode(array($result))

it showed the error like

Fatal error: Call to undefined method Tools::json_encode(). 

So can someone kindly tell me how to solve this issue. any help and suggestions will be really appreciable. Thanks

Hi,

Does your php file extend the Module class ?

Nope...I have used that in another php file but not extended the module class. Can you tell me how to extend that? As I am newbie in prestashop module.

[YopixelAE]

class YourModule extends Module
{
public function assignWhatyouWant()
{
//...your process
$my_results = Tools::json_encode(array($result));
//...
$this->smarty->assign(array(//...));
}
}

You should have something like that.

I have used json_encode not in module file. I have used that in another php file.In template smarty tpl file I have used ajax and in the url file that one is an another php file. In tha file I have used json_encode. So how to use Tools::json_encode in another file

Hi,

Add that in the head of your file :

include ('../../config/config.inc.php'); 
include ('../../init.php');

 

Perhaps the init.php is not necessary. The path to the config.inc.php and init.php have to be updated with your config.

@Vinum thanks for the reply..well when I included

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

and tried 

echo Tools::json_encode(array($result));

then it showed me error like

 Fatal error: Call to undefined method Tools::json_encode()

but if I am using only

echo json_encode(array($result));

then it is not showing any error. But as per prestashop standard I have to use Tools. So can you tell me why it is showing error and how to solve this?

It looks like you're mistyping the function name. It's Tools::jsonEncode() and not Tools::json_ecode()

[bellini13]

it is not difficult to open the Tools.php file in the classes folder and confirm the name of the function exists

[sasaaa23]

Just use Tools::jsonEncode as said in the message.

The name Tools::json_decode is not recognised
