alt1 / alt2 per row instead of per column?

[TrickyD]

I am attaching an image of a forum that has a alternating color scheme I really like. The second attachment shows my progress thus far.

I can't figure out how on earth to do that on the forum homepage.

Any pointers will be greatly appreciated.

Also, I have found that I can change them all to alt1 or alt2 in forumhome_forumbit_level2_post but how can i make them alternate per row?

You can always ask some to upgrade/update this modification. I have not seen it work since 3.0.17, but seem that this maybe the oonly option right now.

thank you for that thread link. that looks like it might do the trick with some tinkering.

Jose, I found a simple solution via that link you gave me...

Pseudo Condition: Alternating Rows
Using this conditional in a looping template (that is, a template the is repeated: postbit, threadbit, forumhome_forumbit* etc) you can easily gain alternating rows. For example, take a look at how this threadbit is done:

<if condition="!isset($altrow)">
    <if condition="$altrow = 0"></if>
</if>
<if condition="++$altrow % 2 == 0">
    <if condition="$altclass = 'alt2'"></if>
<else />
    <if condition="$altclass = 'alt1'"></if>
</if>

<tr>
    <td class="$altclass" id="td_threadstatusicon_$thread[realthreadid]">
        $thread[openclose_editable]

... continue replacing the class with $altclass ...

So let's go through this so you can understand what is happening. The first condition is checking to see if $altrow exists (that is what isset() is for). The first time this template is run, it won't exist -- so we need to give it a value of 0 to start it off.

The next condition:

++$altrow % 2 == 0

First off, the two plus signs before the variable name adds one to the value. So the first time the template is run, $altrow is assigned to 0, and then the plusses make it 1. It would be the same as:

$altrow = $altrow + 1

The '% 2' means 'get the remainder after I divide the left hand number by 2'. We then compare this value to see if it is 0. '% 2 == 0' basically means 'is the number even', since that is the only time a number can be divided by 2 and have no remainder:

* 1 % 2 does not equal 0 (1/2, there will be a remainder), so the class will be 'alt1' (the else part of the condition)
* 2 % 2 does equal 0 (2/2 = 1, no remainder), so the class will be 'alt2'
* 3 % 2 does not equal 0 (3/2, there will remainder), the class is 'alt1'
* 4 % 2 does equal 0 (4/2, no remainder), the class is 'alt2'
* ... etc ...

So combining some simple math and the assignment pseudo condition, we gain the ability to easily insert alternating rows.

I hope others find that as useful as I did!
