Hi guys,

I have a question about pdf generating. Let's say I have a object, it have 3 attributes, and the are:

"name", "size" and "startdate", and I want all the objects to sorted by "start date."

So for now, no matter how I change the code in smarty template, The order of the items in pdf files are sorted by the names alphabetically. They will be like this:

apple | big | 2/1/2018

beer | small | 1/1/2018

cat | big | 3/1/2018

So I made following change:

{foreach from=$objects item="object"}

I tried sorting it by adding the modifier as follow:

{foreach $objects|@sortby:"startdate" as $object}

Sadly, it doesn't work.

So can anyone please tell me how could I do to make "startdate" as default highest priority to sort all the objects.

Thank you very much.

Regards

Zhuo

Sort the objectes where you are getting them from.

Can we know where @sortby comes from?

What you have is a string, of which you are sorting on the alphanumerical order of a string.

If that's all you have, then use a modifier to convert it to a unix time integer, sort on that, then convert back to DD/MM/YYYY.

You may need to modify the modifier to verify that the field to be sorted on looks like a date that can be processed by PHP's strtotime(). If yes, change the array contents. If not, proceed as normal.

Or maybe add a second parameter to indicate what kind of field this is if it is to be treated in any special way.
