php - Display user picture when available -

I am trying to display a user account picture, if the picture field is not 'null' on the base.

If the field is 'empty', then I display the default account picture.

I like {{MYFIELD}} and {{if my file is defined}}

like it

  & lt; Img src = "{% if user.pictureName is zero} {{property ('bundles / nastycodefront / img / userpic.png')}} {% else%} {{property ('upload / image / nastypic_' ~ post. Member ~ '.jpg')}} {% endif%} "alt =" profile picture "& gt;  

or

  & lt; Img src = "{% if user.pictureName is defined%} {{property ('upload / picture / nastypic_' ~ Post.member ~ '.jpg')}} {% else%} {{property ('bundles / nastycodefront / Img / userpic.png ')}} {% endif%} "alt =" profile picture "& gt;  

But trying to get all this custom image.

Do you have an idea of ​​this? Is my code wrong?

Thanks for your help

try it

  & lt; Img src = "{% if app.user.pictureName is defined and app.user.pictureName | length & gt; 0%} {{property ('upload / picture / nastypic_' ~ app User.pictureName ~ '.jpg') }} {% Else%} {{property ('bundles / nastycodefront / img / userpic.png')}} {% endif%} "/>  

Another great method is using the default filter:

  & lt; Img src = "{{app.user.pictureRoute | default ('.png' for 'userpic')}}" />
