Hi guys I wanted to customize my error handling... here's the scenario

1. Define in php controller
Code:

$this->CI->smarty->assign('_setData', $set_data);


2. $set_data contains
Code:

Array
(
    [facebook] => https://facebook.com/ <---- this will be removed i
    [instagram] => https://instagram.com/
    [twitter] => https://twitter.com/
)


4. code in html

Code:

    {$_setData.facebook}



5. I receive an error

Code:

Severity: Notice
Message: Undefined index: facebook
Filename: templates_c/5125124f1e59f2258a491707dcd0a86cf434db62_0.file.home_template.html.php
Line Number: 94
Backtrace:.......


5.I am aware that there is no facebook in the array but I wanted to adjust the error that if the variable (ex. facebook) is not defined in the controller the smarty code (ex. {$_setData.facebook}) will just display null/empty/0.

How can I make this happen in smarty? Is this possible to adjust the smarty?

Let me know if you have question or clarifications to my post.
Thanks in advance! Smile

Smarty is not a programming language. I'm failing to see how is this question related to Smarty in any way.

Use the 'default' modifier

Code:
 {$_setData.facebook|default}
