twig：在HTML属性内的三进制中连接两个字符串

Question

<a class="menu-item" href="{{(haveSubMenu == 'yes')?'#':(item.url|e ~ (item.hash ? item.hash|e : ''))}}"></a>

What I wanna do is simple, if the menu-item has submenu, then its href should be # , if not, then get its URL. But the above code doesn't work, because when ~ convert its operands to string, it converts all & s in item.url to & , which breaks the link.

So what is the correct way to write this?

Answer 1

Try disabling autoscape to all the code with the autoescape tag .

So with this code:

{% autoescape false %}
    Everything will be outputted as is in this block
<a class="menu-item" href="{{(haveSubMenu == 'yes')?'#':(item.url|e ~ (item.hash ? item.hash : ''))}}"></a>
{% endautoescape %}

See the working (and running code with example) in this twigfiddle URL .

If this don't work as you expected feel free to specific some testing data.

Hope this help
