在smarty中找不到带有strpos的单词（prestashop）

Question

I am going to edit the .tpl that generate delivery slips in prestashop.

I want to check if one product in the order contains a particular word in title. If the title contains that word, then I will generate a table in html

After a simple research, I've find that some users used strpos to do that, but my edit doesn't work:

    {if strpos($order_detail.product_name, 'word') !== false}
    ...
    {/if}

Where I'm wrong?

Answer 1

I think you can't use the strpos function in smary's {if} statement.

{if},{elseif},{else} documentation states:

If securty (sic!) is enabled, only PHP functions from $php_functions property of the securty policy are allowed. See the Security section for details.

The Security sections says:

$php_functions is an array of PHP functions that are considered trusted and can be used from within template. To disable access to all PHP functions set $php_functions = null. An empty array ( $php_functions = array() ) will allow all PHP functions. The default is array('isset', 'empty', 'count', 'sizeof', 'in_array', 'is_array','time','nl2br').

strpos is not in this list.

So it seems that Security is enabled on your part.

You should use strpos in your program logic and store the result into a variable which you then check in the smarty template
