Variables in a image link

Carlos Pereira 19 Dec 2009 00:47

Hi friends!

Imagine that I have a page that is a storage of images. Let's say, with animals photos.
Then, in my articles about animals, I want to display the correspondent image to the animal in the page title.
So I thought in using a variable (like %%title%%) in the link of the image required, and include that link in a template… something like this:

[[image storage_page/%%title%%.jpg]]

[[image http://www.url.com/%%title%%.jpg]]

If so, automatically the images with a name similar than the page title are displayed. If the title of the page is Lion, then a photo named lion.jpg would be displayed.

Do you think that is possible?

Sure, you can do that, by tucking that [[image]] code into a _template for the page category. It means you'll have to provide an appropriately named image for every new page. You could load each image into the page itself, or you could put them all in a single page.

I'd suggest using %%name%% instead of %%title%%. That way if anyone renames a page, it won't affect your image URL.

Hi scottplan!

I tried several ways and I think that I get a very nice infobox with some useful automatisms using your suggestion.

Let's see the infobox code:
http://terrasdeportugal.wikidot.com/infobox-concelho:_template

here is the maps storage page:
http://terrasdeportugal.wikidot.com/ilustrar:mapas

now, here is the infobox in a page:
http://terrasdeportugal.wikidot.com/trofa

As you can see, the map is included automatically! Try other page, like Lisboa or Porto and you will see the municipalities map changing. Unfortunately, I can't use that %%title%% solution because certain cities have more than one word in their designation. Per example: "Vila do Conde" has three words and the image module can't deal with spaces. To solve that, I will use %%name%% instead and I need to rename all the pictures to words-separated-by-hifen and witout first capital letters. No problem…

Imagine the advantage to use that solution in an Infobox for my encyclopedia of all the Portuguese villages: Memória Portuguesa. It's only necessary to use the infobox template, containing the code: %%title%%.png , and the respective map is included automatically!
