Mixing
Email adress in text to mailto hyperlink (possible in Twig?)
I have an entity with a text-type attribute called contactInfo. Users can only submit text without html when entering these details in a form. Often an email address is entered somewhere in this textarea (together with more details).
Now when I display this contactInfo I would like adjust any email address to an email address with a mailto hyperlink. For example
Email us at: example@email.com.
should become:
Email us at: <a href="mailto:example@email.com">example@email.com</a>.
How to go about this? Can I do this directly in Twig with some RegEx or Replace filter? Or should I really do this in the controller?

If I were you i'd adjust the input already before storing it in the database, otherwise u could do this by creating your own template class

You can create a twig filter, something like "mailTo"
and do something like
<?php
namespace AppTwig;
use TwigExtensionAbstractExtension;
use TwigTwigFilter;
class AppExtension extends AbstractExtension
{
public function getFilters()
{
return array(
new TwigFilter('mailTo', array($this, 'mailTo'), array('is_safe' => 'html')),
);
}
public function mailTo(string $text)
{
if(preg_match_all('/[p{L}0-9_.-]+@[0-9p{L}.-]+.[a-z.]{2,6}b/u',$text,$mails)){
foreach($mails[0]as $mail ){
$text = str_replace($mail,'<a href="mailto:'.$mail.'">'.$mail.'<a>',$text);
}
}
return $text;
}
}
And then use it like this in your template
contactInfo|mailTo
Either way, don't store "mailto:" or html tags in database when those are always gonna be the same...

As OP statedUsers can only submit text without html

Nov 22 '18 at 13:41
But they don't need to ... that's not how twig filter works, he can add dynamically html tags and render it with raw filter
– Yoann Mir
Nov 22 '18 at 15:44
OP's enduser would not know about any variables so he/she would be forced to type something likebla bla bla mail me at {{ 'info@example.com' | mailTo }}. Not very convenient

Well if OP strips all the html first before applyingrawthen yeah. You could also mark the filter as safe e.g.new TwigFilter('mailTo', array($this, 'mailTo'), array('is_safe' => 'html'));
