Question

我试图更改我的订单 - confirmation.tpl，之后显示几个错误我尝试添加facebook像素代码来跟踪订单。

我的更改

我添加了OrderConfirmationController.php

        $cart = new Cart((int)($this->id_cart));
    self::$smarty->assign(array(
        '_order' => $this->id_order,
        '_value' => $cart->getOrderTotal()
    ));

之后我添加了order-confirmation.tpl

 <!-- Facebook Pixel Code -->
<script>
!function(f,b,e,v,n,t,s){if(f.fbq)return;n=f.fbq=function(){n.callMethod?
n.callMethod.apply(n,arguments):n.queue.push(arguments)};if(!f._fbq)f._fbq=n;
n.push=n;n.loaded=!0;n.version='2.0';n.queue=[];t=b.createElement(e);t.async=!0;
t.src=v;s=b.getElementsByTagName(e)[0];s.parentNode.insertBefore(t,s)}(window,
document,'script','//connect.facebook.net/en_US/fbevents.js');

fbq('init', 'xxxxxxxxxxxxxx');
fbq('track', "PageView");
fbq('track', 'Purchase', {value: {$_value}, currency: 'USD'}); 
</script>

/></noscript>
<!-- End Facebook Pixel Code -->

如你所见，我试图通过$ _value获得价值

错误是

   Fatal error: Uncaught --> Smarty Compiler: Syntax error in template "/var/www/presta/themes/mytheme/order-confirmation.tpl" on line 43 
"!function(f,b,e,v,n,t,s){if(f.fbq)return;n=f.fbq=function(){n.callMethod?" - Unexpected ".", expected one of: "","" , ")" <-- thrown in 
/var/www/presta/tools/smarty/sysplugins/smarty_internal_templatecompilerbase.php on line 43

谢谢

我修正了改变那部分的问题，也许有人需要有一天facebook Pixel的事情：）

关于order-confirmation.tpl因为聪明而需要添加 {literal}

 !-- Facebook Pixel Code -->
<script>
{literal}
!function(f,b,e,v,n,t,s){if(f.fbq)return;n=f.fbq=function(){n.callMethod?
n.callMethod.apply(n,arguments):n.queue.push(arguments)};if(!f._fbq)f._fbq=n;
n.push=n;n.loaded=!0;n.version='2.0';n.queue=[];t=b.createElement(e);t.async=!0;
t.src=v;s=b.getElementsByTagName(e)[0];s.parentNode.insertBefore(t,s)}(window,
document,'script','//connect.facebook.net/en_US/fbevents.js');

fbq('init', '1445570592421898');
fbq('track', "PageView");
fbq('track', 'Purchase', {value: {/literal}'{$_value}'{literal}, currency: 'USD'});  
</script>

<!-- End Facebook Pixel Code -->

Answer 2

在Smarty模板中，{和}大括号将被忽略，只要它们被空格包围。

所以只需在每个大括号前后插入一个空格：

<!-- Facebook Pixel Code -->
<script>
!function(f,b,e,v,n,t,s) { if(f.fbq)return;n=f.fbq=function() { n.callMethod?
n.callMethod.apply(n,arguments):n.queue.push(arguments) } ;if(!f._fbq)f._fbq=n;
n.push=n;n.loaded=!0;n.version='2.0';n.queue=[];t=b.createElement(e);t.async=!0;
t.src=v;s=b.getElementsByTagName(e)[0];s.parentNode.insertBefore(t,s) } (window,
document,'script','//connect.facebook.net/en_US/fbevents.js');

fbq('init', '0123456789012345');
fbq('track', "PageView");</script>
