How can I use a special Font awesome character instead of the text parameter with `link($text, $url, $attributes)?

I tried the following code for the Contact us button, but it doesn't show the envelope symbol properly. Instead, it shows #xf0e0;.

{{ link('', 'base:contact', { 'class':['fa', 'fa-lg'] }) }}`

Is there any way to output that symbol without using the fa-envelope CSS class?

  • but whatever i try i cant show "Envelope" character properly what exactly is properly? Does the character not show up at all? or??? – No Sssweat Jul 24 '16 at 22:20
  • Yes, character not show up at all and instead of to showing the "Envelope" symbol is shown it's value " . – Mojtaba Reyhani Jul 24 '16 at 22:54

If you are really set on not using the class (and want to use the unicode char) just don't use link(), the $text parameter is escaped. Just build a link normally:

<a href="{{ path('contact.site_page') }}" class="contact-us-link"><i class="fa fa-lg">&#xf0e0;</i></a>

  • I'm not sure if fa class sets FontAwesome for the element itself, only the :before pseudo-element. – mradcliffe Jul 25 '16 at 20:01

The point of the FontAwesome selectors is that you do not need to print out the Unicode equivalent for the character. FontAwesome usually works by adding a pseudo element before or after the HTML element using the class.

In this case, use the fa fa-envelope classes and optionally add in a class to hide the text with a text-indent or something.

{{ link('Contact Us', 'base:contact', { 'class':['fa', 'fa-envelope', 'fa-lg', 'contact-us-link'] }) }}

  • Thank you so much for your Consultation, But is there any method that i can achieve this purpose without using "fa-envelope" Class. – Mojtaba Reyhani Jul 24 '16 at 23:53
  • @MojtabaReyhani what happens if you remove 'fa-envelope', in the above code? does it not work? – No Sssweat Jul 25 '16 at 2:11
  • @Sssweat Thank you for your attention, yes, by remove the 'fa-envelope' class, in the above code, it does not work and doesn't show envelope symbol. – Mojtaba Reyhani Jul 25 '16 at 8:00
  • Why do you not want to add the fa-envelope class. That is exactly how you are supposed to use FontAwesome. If you want to do /not/ use that class, then you have to reconstruct the CSS that is already written for you. It is completely duplicate code to not use that class. – mradcliffe Jul 25 '16 at 14:30
