I write PHP inside JS in the following way
alert(<?php echo __("Error-login") ?>);
echo__("Error-login") correlates with an xml to translate in two languages with symfony, but now it does not work.
How do I fix this?
Your line becomes
alert(Error-login);
As you can see, you are missing the quotes:
alert('Error-login');
If somebody uses quotes in the translation, this will also generate an error:
alert('Error's are here');
So you need to escape single quotes before you pass it to Javascript.
;in'<?php echo __("Error-login"); ?>'
