User blog:Thisismyrofl/Customizing an old-new-style infobox

Hey! This is Thisismyrofl, an admin here on Community Central. I wanted to see if I could explain how to use the new style of Template:Infobox (new as in September 2012). On your left, you see a basic infobox made in the new infobox format. We'll learn how to make an infobox of our own to meet our specific needs!

I'm referring here to the default styles, that is, those that were on the Starter Pages Wiki's Template:Infobox page. Since every newly created wiki, at the time of its creation, is given a copy of every page and template on Starter Pages Wiki, that means that there are thousands of wikis that came with the old style, and thousands founded after September 2012 that came with the new style.

Plan the infobox
Let's make a plan! Think about what you want your infobox to look like, and decide about visibility.

If I wanted to make a template "Template:Infobox Wolf3D level" for the game Wolfenstein 3D, it might follow this format:

Template:Infobox Wolf3D level
 * Title
 * Image
 * Image caption
 * Heading: "Treasure"
 * Number of crosses	(default: "0")
 * Number of chalices	(default: "0")
 * Number of chests	(default: "0")
 * Heading: Other stats
 * Par time		(default: hidden)
 * Song that plays	(default: hidden)
 * Number of secrets	(default: hidden)

If a row is left empty when the template is called, we must decide whether it should give a default value (such as "Unknown") or be hidden (that is, the row won't show up at all). Jump to the section for more information. Mark on your plan how you want each row to be treated.

Default syntax
Let's also make the default syntax for the new template! This can be copied into the template's documentation. It should look something like this.

This is what will be pasted into an article and then filled out to make a fully-fledged infobox appear on the article! But before it works, you need to customize the page "Infobox Wolf3D Level" on your wiki.

Now that we've planned it out, let's customize our infobox.

Understanding the code
Let's take a look at the standard code of Template:Infobox. Remember that this is the default code, and not necessarily the code that will be seen on your infobox. I've colored it myself for clarity - you're not likely to see this kind of coloring when you actually edit.

Visibility
There are two types of infobox rows: those with default values and those which are hidden if no value is given. By default, the first three have default values, and the fourth, fifth, and sixth are hidden.

Below, two infoboxes: on the right, I have filled in the template entirely, but on the left I have left all six fields blank. Because they're blank, the first three return the default value "Unknown". The fourth, fifth, and sixth are differently coded: when no value is specified, they do not appear at all. Keep this difference in mind.

Edit your infobox!
I'll assume that at this point, you already have an infobox or infobox template at the location "Infobox Wolf3D level" on your wiki, or whatever you've decided to name it. If you haven't, take a look at my other blog: User blog:Thisismyrofl/Creating a new-style infobox.

Any part of this can be modified, but look at the green, red, and blue parts. Those are the important parts we need to work with. Until your abilities with templates have improved, it's best to leave the purple and orange parts alone.

Editing headings

 * Click here to see how I did it!

By default, the infobox has two heading snippets, highlighted in green in my above code. Their default texts are "some attributes" and "other attributes".  ! colspan="2" |  Some attributes

The default texts aren't really specific enough for a lot of wikis. Just change the text "Some attributes" and "Other attributes" (highlighted here in yellow ) to your liking! You can leave the rest of the code intact.

As always, you can remove either or both of the headings if you want (just delete any code that looks like the above heading) or add headings (just paste in a copy of the above code).

Editing rows with defaults

 * Click here to see how I did it!

By default, the infobox has six rows, the first three of which have the property that when a parameter is undefined, the row still shows - showing instead a default text.  ! First

! Second

! Third

Each of these three obvious snippets is a row, but the default headings ("first", "second", "third") don't work for a lot of people. So we can feel free to change them! I've highlighted the bits of code you'd edit.
 * 1) Change the header text (here highlighted in cyan ) to read whatever you want to appear on the left side of the infobox row.
 * 2) Change the parameter name (here highlighted in green ) to display the parameter name you decided on in your default syntax earlier. For example, my first parameter was to be "crosses", so I'd type   where the ellipsis ("...") stands for the default text - see the next step.
 * 3) Change the default text (highlighted in yellow ) if you want. The default action is that an unspecified parameter will display the code   which returns an italicized: "Unknown". You can change the default text to whatever you want, and format it with italics, without italics, or otherwise. For example, my default number of crosses was to be "0". So, combined with the parameter name from earlier, I'd type
 * 4) I've highlighted and explained how to edit the "First" row, but you can follow the same steps for the second and third.

As always, remember that you can remove one, two, or all three of the above snippets of code in order to use fewer rows with defaults (perhaps if you want all your rows to be hidden), or you can add your own.

Editing rows that hide

 * Click here to see how I did it!

By default, the infobox has six rows, the fourth, fifth, and sixth of which have the property that when a parameter is undefined, the row does not appear at all. Contrast with the above behavior.  { {#if: | ! Fourth { {!}}
 * }}

{ {#if: | ! Fifth { {!}}
 * }}

{ {#if: | ! Sixth { {!}}
 * }}

Each of these three obvious snippets is a row, but the default headings ("fourth", "fifth", "sixth") don't work for a lot of people. So we can feel free to change them! I've highlighted the bits of code you'd edit.
 * 1) Change the header text (here highlighted in cyan ) to read whatever you want to appear on the left side of the infobox row.
 * 2) Change the parameter name (here highlighted in green ) to display the parameter name you decided on in your default syntax earlier. For example, my first parameter which I wanted to be hidden was to be "par", so I'd type   in the first spot and   in the second. (It makes a difference!)
 * 3) I've highlighted and explained how to edit the "Fourth" row, but you can follow the same steps for "Fifth" and "Sixth".

As always, remember that you can remove one, two, or all three of the above snippets of code in order to use fewer rows with default action to hide, or you can add your own.

We're mostly done!
Now you can save the page! Enjoy your new infobox! Paste your default syntax into an article and fill it in. The infobox I made looks like the one on the right. Super pretty!

Finishing touches
The above steps are the important part, which is why I had you save the page. There's a few other things that we can do, but your template will function fine without them.

Default title

 * Click here to see how I did it!

The  parameter controls what appears at the top of the infobox, in the fourth row of the code. ! class="wikia-infobox-header" colspan="2" | By default, you have to fill it in, otherwise your infobox will have a nasty italicized "Unknown" at the top. A smarter behavior can be brought about by switching in a  magic word: ! class="wikia-infobox-header" colspan="2" | Now, if the title is left blank, it'll default to the name of the page. You might still have to edit the  parameter on some pages.

Documentation
Templates are kinda complicated, so it's best to have a little snippet of information on how to use it at the bottom of the template. You'll notice that at the bottom of the default template code, there's a  template call. This calls Template:Documentation, which varies from wiki to wiki, but in any case, it will transclude the page located at Template:Your template/doc.

Here's a wise layout for your new template's documentation:

Default syntax
Paste this into the page, then fill it in, to use the template.

&lt;/pre>

Paste that to Template:Infobox Wolf3D level/doc (substituting in the name of your infobox) on your wiki Remember, though, that you need to substitute in your default syntax for what I've pasted here.

Be bold!
I've only outlined the basics of editing infoboxes. Feel free to be bold and try editing them further! If you mess up, you can always undo the edits from the page's history.
