Alternating colours

[harvey]

I'm using an advanced index to display just the content_longtext for every item of content in a definition, and I'd like to alternate the colour of each result for ease of reading.

I've found a very simple method for alternating table row colours here:

http://www.marvinsplaypen.com/php/table_row_colors.php

And when I create a simple php page myself I can get this to work, however I'm struggling to get it to play nicely with MonkeyCMS.

Within my page template I have this:

%% $cnt = 0; %%

(advancedindex|AdvancedIndex:MyIndex|||1)

and the advance index uses this template:

<h2 style="color:
%% addToOutput((++$cnt)%2==0) ? 'black' : 'red'; %%
;">
[content_longtext]
</h2>

but in my rendered page the h2 tags are output like so:

<h2 style="color:;">

neither red nor black is being inserted.

Any ideas what I'm doing wrong?

I'd probably not use the $cnt variable - instead, I'd pull in the content array and pop a variable into that:

%% global $arrayContent; $arrayContent['cnt'] = 0; %%

(advancedindex|AdvancedIndex:MyIndex|||1)

<h2 style="color:
%% global $arrayContent; addToOutput((++$arrayContent['cnt'])%2==0) ? 'black' : 'red'; %%
;">
[content_longtext]
</h2>

Let me know if that works

Thanks for that Colin, I'm still getting the same result though?

OK - may be that the addToContent function doesn't work with it then. I'll post an alternative in a sec

[harvey]

Actually on inspection of the rendered code I'm getting

<h2 style="color:;">

for the first result,

<h2 style="color:1;">

for the next etc...

[Colin]

Try this:

<h2 style="color:
%% global $arrayContent; if ($arrayContent['cnt'] == 1) ** $arrayContent['cnt'] = 2; addToOutput('black'); ** else **  $arrayContent['cnt'] = 1; addToOutput('red'); ** %%
;">
[content_longtext]
</h2>

Replace the **'s with curly brackets.

[harvey]

ignore me, didn't read the curly bracket thing!

taa-daa! I works, thanks a million Colin.

Is it easy to explain in lay-mans terms the difference between what I was doing and your solution?

Not really - I'm not really sure how the previous solution should have worked - obviously some short hand way.

Mine is probably a bit messier, but works

Gotcha, that's great, and very useful, I can see me using this a lot!
