pagination by date

[sakkoulas]

hi people

can anyone tell me some tips to paginate by date.
i want to show todays day posts, and have two links with next day and before day.
i can't figure how to check if there are posts from past dates.
thanks

Examples? Any code yet? 

Paginate? Do you mean with pager? 1 | 2 | 3 ?

Or simply with $page->prev() $page->next() ?

hi soma no just $page->prev() and $page->next();

I have experimented with ryan code that i have found in forum

[Soma]

IT would help greatly to see a example what you want to archive exactly AND what the structure is you have with "posts".

I'm a little bit ashamed for my code but ok

$today = date('Y-m-d');
$dayBefore =  date("Y m, d", strtotime("yesterday"));
echo "today: $today </br>";
echo "lastdate $dayBefore </br>";
$results = $pages->find("sort=-publish_from, categories=$page,publish_from>=$today");
 foreach ($results as $result) {
 	echo "$result->title </br>";
 }
 
$next = $results->getNext($result); 
$prev = $results->getPrev($result); 

if($prev) echo "<a href='$prev->url'>Prev</a> ";
if($next) echo "<a href='$next->url'>Next</a> ";

i am using blog profile module so i have

posts parent 

with post children

and categories

with category items

[Soma]

There's million ways to, but I think you first need to make clear what url you'll need to display the post of today or any day when you go next or previous day.

I don't know the blog profile much. How is the category the $page? Are you on a category page when you want this to display?

I don't think prev() next() will work here.

I think best is you would use url segments, so you would have like /posts/today, /posts/dd-mm-yyyy

But where is the category coming from then?

Posting code to github gist... 

Much easier here is the code:

Something to start with and think about , not really tested and sure about the date to compare with publish_from=$prevday

as those will be timestamps, but you could convert them first.

Just tested a little around and cleaned up script and added comments.

[sakkoulas]

yes i am on a category page
from other sites i can see they use /posts/today,  and /posts/dd-mm-yyyy for other pages so i think this is the way
i use url segments i have a pagination there for test purposes
 

ok i'll try with this, thanks soma

[Soma]

You'll have to adapt it to your situation and test it out, that's all I can do.

[sakkoulas]

ok, thanks a lot

[Soma]

Now tested and put the code on gist github:

https://gist.github.com/somatonic/5067314

I have some minor correction and added comments, some improvement to show how to handle 404 and dates.

[Soma]

I created another version to show how to create this navigation with post which have a date with daytime. So it covers a range of 24 hours and not only a date without time.

It looks for the next post found in future and past, so it will still work if there's a day in between where no posts are published.

I created a new gist snippet for anyone interested as reference:

https://gist.github.com/somatonic/5068777

It will give you something like this

this is fantastic thanks again soma
