odd and even aren't calculated by the sequence-number but by -index, which starts at 0, which is defined as an even number... HTH Martin Alfredo P. Ricafort schrieb:
Hi,
I have this code that display images in a 2-column table. The idea is for <dtml-in> to loop inside a folder containing these images. When the counter is odd, an opening <tr> will be inserted; and when a the counter is even a closing </tr> is inserted as well.
--------------------- | Image 1 | Image 2 | --------------------- | Image 3 | Image 4 | ---------------------
The code is like this:
<table width=100% border=1> <dtml-in objectValues>
<dtml-if sequence-odd> # Check if the sequence no. is even <tr> and create a row. </dtml-if>
<td> # Create a column and <dtml-var sequence-number> insert the image or text </td>
<dtml-if sequence-even> # Close the table if even </tr> </dtml-if>
</dtml-in> </table>
When I ran this code, I noticed that in the first iteration, when the sequence-number is 1, the condition <dtml-if sequence-odd> is not satisfied while the <dtml-if sequence-even> is! So the first few lines of the generated HTML would appear like this. Notice that the 1 column (<td></td>) is created first before the row.
<table width=100% border=1>
<td> 1 </td>
</tr> #
<tr> : :
So, could somebody explain to me what is going on here. Why can't Zope recognize the first iteration as an odd number, when the value of the sequence-number is 1. And why is the statement <dtml-if sequence-even> is satisfied at this point?
Thanks.
