OK, so I started the thread yesterday, at half past eleven p.m. This morning I had an answer. Worked right away. What a forum.
GaneshXL, ABSOLUTELY BRILLIANT! Thank you so much for your valuable help!
@other-newbies-like-me:
If you want multiple values of some sort, e.g. different t-shirt colors available, to be associated with a document (page) for that t-shirt in the form of (readable) clickable links:
1. Create a document for the t-shirt. (Left hand document tree in default installation manager)
2. Under Resources/Manage resources/Templates, create a template for the front end design of the document. Use the template for the document.
3. Under Resources/Manage resources/Template Variables (TV) create a TV. Variable name: [*colors*], Caption: Colors, Input Type: Check box. -Input Option Values: red==[~[*id*]~]&color=red || blue==[~[*id*]~]&color=blue || white==[~[*id*]~]&color=white etc (the "==" means: LabelToBeShownWhenEditing==ActualValueSavedToDatabase), Widget: delimited list. Delimiter: ,
4. Under Template Access (still in the TV) be sure to check the Template you created at 2. Save the TV.
5. Under Resources/Manage resources/Snippets, create a snippet, name it whatever you want, e.g. [[getColors]]. Copy and paste ganeshXL:s code into the Snippet code (php) field. Save it.
6. Go to edit the t-shirt document. There should be an entry under Template Variables called Colors. Check applicable colors.
7. In the document content, or in the Template, put the following call: [!getColors!] where you want a list of clickable color labels to be output linking to their URL.
The links in the above example will add an "&color=red" to the current page URL when red is clicked. You could use that for conditional switching of product images for example.
