XF 2.2 How to count inside foreach in a template?

[grantus]

I've looked around but can't seem to find what I'm looking for.

I have my foreach loop:

<xf:foreach loop="$view" value="$value">
</xf:foreach>

But I need to get the count. I noticed there's count="$count" in the approval_queue template but apparently it doesn't work?

What would be the best way to do a count++ inside my foreach?

You can do <xf:foreach loop="$array" value="$item" i="$i"> to get the current count in $i, or you can just do {{ count($view) }} if you want the total count.

I was trying that but it doesn't seem to want to work.

For example, I want to get odd numbers so I tried this but no luck:

<xf:if is="{$i} % 2">
 // odd numbers
</xf:if>

Did you put i="$i" in your <xf:foreach> tag? Using what you posted verbatim works just fine for me.

Yes. It seems to be working now though. Weird.

Also, I just tested it by giving it another name instead of $i and it doesn't work. Why does it have to be $i?

It doesn't, you can give it any name:

<xf:foreach loop="$array" value="$item" i="$any">
    {$any}
</xf:foreach>

    {$any}
</xf:foreach>

Sorry, I mean the whole thing, so why would it be i=?

That is just the name that was chosen for the iterator count attribute of the <xf:foreach> tag. Admittedly it's not super descriptive.

Consider HTML, where you could have <div class="class"> if you wanted, but you could also have <div class="anything-else">.

Ok, I figured that. Makes sense! Thanks for the help.
