Display images in PyroCMS depending on its {{ name }}-tag

Question

I need to display some images from a folder depending on its {{ name }}.

The names of my files look like this:

• foo.jpg
• foo_blur.jpg
• bar.png
• bar_blur.png

Now I need to do something with the blurred-image. This is what I tried, but no success:

{{ files:listing folder='1' }}
    {{ if { helper:strpos haystack='[[ name ]]' needle='_blur' } }}
        {{ files:image id='{{ id }}' }}
    {{ endif }}
{{ /files:listing }}

Currently it just does nothing. It seems that the strpos returns allways false. Any ideas what I'm doing wrong?

Answer 1

Got it by myself, thanks to Leon Stafford:

Just remove the brackets [[ ]] and its surrounding quotes

{{ files:listing folder='1' }}
    {{ if { helper:strpos haystack=name needle='_blur' } }}
        {{ files:image id='{{ id }}' }}
    {{ endif }}
{{ /files:listing }}

Answer 2

You should use the same curly braces for the name variable as you are for the id:

{{ files:listing folder='1' }}
    {{ if { helper:strpos haystack='{{ name }}' needle='_blur' } }}
        {{ files:image id='{{ id }}' }}
    {{ endif }}
{{ /files:listing }}
