include image rendition conditional - Newscoop Support Discussions on Sourcefabric Forum

BAUMANN Thomas

Hi all,

I tried to get a conditional to check if there is a image/thumb/etc. defined, and if not, i want to display a placeholder for each _tpl/img/img_XxY.tpl.
No success was with $image->defined.
Which is the recommended way, always display an specific image if e.g. {{ include file="_tpl/img/img_250x167.tpl" where="front-bottom" }} is chosen.

Thanks for your help in advance.
Thomas.

Please tell me as well where the placeholder images should be saved on webserver.

Hi,

to check if rendition exists, you can use this

<img src="{{ $image->src }}" width="{{ $image->width }}" height="{{ $image->height }}" class="tencol last" rel="resizable" style="max-width: 100%" alt="{{ $image->caption }} (photo: {{ $image->photographer }})" />

<em>{{ $image->caption }}</em>

</figcaption>

</figure>

{{ if trim($_img) }}{{ $_img }}{{ else }}...}{{ /if }}

In this example, {{ capture }} captures processed code and assigns it to variable; then you only need to check if variable is empty or not.

Hi Ljuba,

Might is be possible to check {{ if ! $gimme->article->image->thumbnailurl }} ? Or wont there be an thumbnail?

Where should placeholder pictures being placed ? (or referenced) - which is the <img src="{{ xxx }}"> path, when placing images below current template, e.g. /themes/publication_1/theme_1/_img/ (which variable contains /themes/publication_1/theme_1/_img/ ) ?

You can put placeholder images anywhere inside your theme's folder, for
example /img. Accessing them is easy with {{ uri
static_file="img/placeholder.jpg" }}

Best, Ljuba

Hi Ljuba, I did this, but the placeholder is not being resized.
How could this being solved?

I think of something like:

                <figure{{ if $where == "author" }} class="fourcol"{{ /if }}>
                    <a{{ if $where == "section" }} class="fourcol"{{ /if }} href="{{ url options="article" }}">
                        <img src="{{ uri static_file="img/placeholder.png" }} " width="{{ $image->width }}" height="{{ $image->height }}" rel="resizable" style="max-width: 100%" alt="{{ $image->caption }} (photo: {{ $image->photographer }})" />
                    </a>
                </figure>

How is the <figure class="XXX"> being created, as currently is gets not filled by "class=threecol" or "class=eightcol" ?

Best regards,
Thomas.

The class is very important, as it has to be inherited by the above class, so it must not be static.

Hi,

in this case class applied to <figure> is created when variable $where has value 'author', and this value is forwarded from parent template (let's say article.tpl) to this included template like this
