Hello everyone!
I need to put more dates of publication of the article during insertion. I noticed that there are only two fields ( start date and end date ) publication .
For example, I would make sure that an article be published on dates spaced out in a week ( ie . Monday, Tuesday , Saturday and Sunday ) .
And it's possible with a code change? or is there some other solution?
Thank you!

You can use K2's extrafields to add more dates to the post.

We are building a site for a cinema.
the characteristics of the articles of K2 are perfect for my work. The only difficulty I have is in showing these articles with different dates (like dates of the film). I repeat the example of the previous topics (That I would make sure an article be published on dates spaced out in a week (ie. Monday, Tuesday, Saturday and Sunday)).
I write this because filtering for custom fields (event date) does not help me to do this.

There are extensions posted at the JED which offer filtering by extrafields.
I think you will find them usefull

You can also manually select items to display in the K2 Content module's settings.
