[Solved] Smarty3 Escape Not Working With Blocklayered Json

[yaniv14]

I am using Prestashop 1.6.1.4 and all seem to be working fine except escaping json returned data from ajax call.

Using blocklayered navigation giving error 500 when trying to render/escape json data from server to product-list.tpl.

Regular pages which use the same file (product-list.tpl) working just fine.

The error I am getting is:

Undefined index: escape in/home/xxx/public_html/cache/smarty/compile/e4/a1/fd/e4a1fd2f5285aae65055ce86ad9af69b31b94166.file.product-list.tpl.php on line 95

Fatal error: Call to a member function escape() on a non-object in/home/xxx/public_html/cache/smarty/compile/e4/a1/fd/e4a1fd2f5285aae65055ce86ad9af69b31b94166.file.product-list.tpl.php on line 95

This is a brand new server and at the beginning I had also an issue when trying to truncate chars so I had to install mbstring thru EasyApache 3 and everything was fixed.

My guess is that I am missing some mod/extension/plugin for Apache or PHP.

Any help will be apreciated.

HI,

I have the same problem.

Can you explain what did you do to solve it exactly?

 

Thanks!

[yaniv14]

I am still struggling with this module on different sever and it seems that it has some issues with smarty cache.

Try to disable Smart cache in BO and clear all cache and check if its working for you.

 

For now I disabled the smarty cache to get this module working but it slows down the page loading time because the templates are not cached.

Thanks!!!

 

I have disabled Smart Cache and clear all caches and now is working!

I don't understand, yesterday i did it and not work.

 

I will proof and investigate to look for a better solution.

I posted that question on stackoverflow and I thought he was fixed but I still get that issue.

I have 2 shops on ps 1.6.1.4 one with nginx and one with apache and both have the same issue.

So I still don't have any lead.

[Kerm]

I have on one server installed 1.4....1.6.0.14 and 1.6.1.4 versions, and only 1.6.0.14 have this issue...

[yaniv14]

Are you using one page checkout module?

[Kerm]

Are you using one page checkout module?

 

I use onepagecheckoutps module http://addons.prestashop.com/ru/8503-one-page-checkout-ps-easy-fast-intuitive.html

On both versions 1.6.0.14 and 1.6.1.4

Replace the file classes/OnePageCheckoutPSCore.php with the one I attached here and let me know if its working for you.

Make backup of the file just in case.

 

OnePageCheckoutPSCore.php

OnePageCheckoutPSCore.php

 

You think this file can somehow cause these errors in product-list.tpl file?

[yaniv14]

Yes, look at the original file and you can see the smarty escape override.

[Kerm]

Yes, look at the original file and you can see the smarty escape override.

 

I have newest version of this module and my file is different from yours.

 

look please:

OnePageCheckoutPSCore.php

 

I try use your file, but got errors.

And is it working?

Ok i think is done, i change on this:

 

    public function __construct($name = null, $context = null)
    {
        $this->errors      = array();
        $this->warnings    = array();
        $this->params_back = array();
        $this->globals     = new stdClass();
        $this->fillGlobalVars();

        parent::__construct($name, $context);

        $file_smarty_config = _PS_ROOT_DIR_.'/config/smarty.config.inc.php';
        if (is_file($file_smarty_config)) {
            if (is_writable($file_smarty_config)) {
                $content = Tools::file_get_contents($file_smarty_config);

                if (!strstr($content, 'escapePTS')) {
                    $content .= '
                        //CODE MODULES PRESTEAMSHOP - PLEASE NOT REMOVE
                        //--------------------------------------------------------------------------------------------------------
                        smartyRegisterFunction($smarty, "modifier", "escape", "escapePTS");
                        function escapePTS($string, $esc_type = "html", $char_set = null, $double_encode = true, $as_html = false)
                        {
                            $smarty_escape = SMARTY_PLUGINS_DIR."modifier.escape.php";
                            include_once $smarty_escape;

                            if (!$as_html && is_callable("smarty_modifier_escape")) {
                                $string = call_user_func("smarty_modifier_escape", $string, $esc_type, $char_set, $double_encode);
                            } else {
                                $string = html_entity_decode($string);
                            }

                            return $string;
                        }
                        //--------------------------------------------------------------------------------------------------------
                    ';
                    file_put_contents($file_smarty_config, $content);
                }
            }
        }

        $this->smarty = $this->context->smarty;
        $this->cookie = $this->context->cookie;

        $this->fillConfigVars();
    }

And remove escape function at end of file....

[Kerm]

And is it working?

 

Yes, thx!

 

PS.: I have installed this module on 1.6.1.4 also, and here i dont see any problem. For me, problem only on 1.6.0.14

Thanks it's working for me. I'm on Prestashop 1.6.1.1 with onepagecheckoutps v2.1.4. I was having errors in admin, when using the search function, received error 500:

Undefined index: escape in cache/smarty/compile/c9/c5/9d/c9c59dbc5a2d699170b6a31908f00d90b430ac61.file.blockcart.tpl.php on line 70

It only worked if I cleared the cache. But now I don't see these errors anymore. Thanks!
