It's me again; the old shade-tree-programmer. I am in need of some more help with my blog infusion. Please; w/o criticism of my quirky coding habits and procedures.
Everything is working beautifully except my calendar module's article links. Actually that works correctly too as long as it is hard-coded into the script. This is the hard-code
that is an existing part of my calendar script:
$days = array(
        1=>array('../grims_blog/filtered.php?post_id=8','link'),
        7=>array('../grims_blog/filtered.php?post_id=9','link'),
        23=>array('../grims_blog/filtered.php?post_id=12','link'),
        24=>array('../grims_blog/filtered.php?post_id=13','link'),
);

This produces linked articles for the given DAY in the calendar correctly. What I need to do is make this array a dynamic one after querying my database table GRIMS_BLOG_POST_TOPIC.
where I need to get the art_day(article day) and the post_id. Then I need to build a string that is the same as the arrays in the above code. Something like this:

1=>array('../grims_blog/filtered.php?post_id=8','link'),
day + "=>array('../grims_blog/filtered.php?post_id=" + post_id + "','link'),"

Here is the code from my create_post script that records the post_id, topic_id, month and day correctly.
$result = dbquery("INSERT INTO ".DB_GRIMS_BLOG_POST." (post_id, topic_id, post_title, post_body, post_img, post_thb, posted, active) VALUES ('', '$topic_id', '$post_title', '$post_body', '$post_img', '$post_thb', '$posted.', '$active')");
$last_id = db_lastid();
$mymon = date("n", $posted);
$myday = date("j", $posted);
$result = dbquery("INSERT INTO ".DB_GRIMS_BLOG_POST_TOPIC." (post_topic_id, post_id, topic_id, art_mon, art_day) VALUES ('', '$last_id', '$topic_id', '$mymon', '$myday')");

I'm not sure how to go about doing the query and then building the links. If this makes sense to anyone I sure would appreciate any help with this.

Maybe something like this (sorry adding as code is not working for me atm):

[color=#660000]$result [/color]= dbquery ("Select art_day, post_id From DB_GRIMS_BLOG_POST_TOPIC Where .....")
[color=#000080]if [/color](dbrows([color=#660000]$result[/color])) {
[color=#660000]$data [/color]= dbarray([color=#660000]$result)[/color]

[color=#660000]$na [/color]= [color=#000080]array[/color]();

[color=#000080]while [/color]([color=#660000]$data [/color]= dbarray([color=#660000]$result[/color])) {

[color=#660000]$mdata [/color]= [color=#000080]array[/color]();
$mdata['title'] = [code]'../grims_blog/filtered.php?post_id=".$data['post_id']."';
$mdata['link'] = 'link';

[color=#660000]$na[][/color] = [color=#660000]$mdata[/color];
}

}


You can check the contents of the array by adding statement var_dump($na) as test after the loop.

Well I think my brilliant idea is just not going to work. No matter what I do and no matter how I configure this thing it won't work. The
[code]$days = array(

in the script screws everything up. When I try to include the "query coding" within that array it will not work. I really appreciate your attempts at helping me douwe. It does generate the right stuff I just can't incorporate it in the original script so I suppose I'm going to abandon my pursuit.[/code]

When I do that in the calendar script itself this is what I get:
array(4) {
[1]=> array(2) { [0]=> string(36) "../grims_blog/filtered.php?post_id=8" [1]=> string(4) "link" }
[7]=> array(2) { [0]=> string(36) "../grims_blog/filtered.php?post_id=9" [1]=> string(4) "link" }
[23]=> array(2) { [0]=> string(37) "../grims_blog/filtered.php?post_id=12" [1]=> string(4) "link" }
[24]=> array(2) { [0]=> string(37) "../grims_blog/filtered.php?post_id=13" [1]=> string(4) "link" }
}

However I get this printed to the screen above the calendar proper for a VERY VERY LONG time: I assume for each day of the month:

It's the same but with an added array for the "link". What it boils down to I think, is a 4 dimensional array. I have no experience with multi-dimensional arrays. Consequently I have absolutely no idea how to solve this.

This is the most bizzare thing I have ever seen. I can generate the complete code but no matter where I put it in the calendar script it won't work. This is an image of my test file's output:

Im sorry got busy with sorting out work for this site. I would like to post my share of input.

​I see that the column has day and month. To query multi column is slower than to query on 1 single column. I prefer the datestamp int(10) method. This would have been easier with this query to sort month and day using php. 

​​​​​​Insert to blog item using php timestamp. aka time(). To fetch the items would be easy with these:

// February 2020
WHERE MONTH(FROM_UNIXTIME(blog_timestamp)) = 2 AND YEAR(FROM_UNIXTIME(blog_timestamp)) = 2020

i would also add selector in SQL to give me the month and the year as well to sort into query output. 

SELECT * , MONTH(FROM_UNIXTIME(blog_timestamp)) as month, YEAR( FROM_UNIXTIME(blog_timestamp)) as year

So dbarray($res)) will have month and year in your dump. To sort into array I would do this:

$data['link'] = BASEDIR."....?id=$id";

$cache[ $year ][ $month ][ $id ] = $data;

​To callback items on your cached data.. 

Say month 2, Year 2020. will be

$feb =$cache[2020][2];

it will give u 2 dimension array you can loop like this

foreach ($feb as $id => $data) {
 print_p($data);
}

You can also use SQL to add selector DAY(FROM_UNIXTIME( datestamp )) as day, if you need it.

I did not include isset check or empty check in my code above. You can freely add them if needed.

That is how I would design dated stuffs with main priority in sortable and filter control at SQL level. PHP end is just mostly decorative adds and parser for best practise. I will not filter results using php.. proven very slow to render.

OK thanks Chan. I have a new problem that I need help with. I have changed my infusion table field from 'posted' int(10) TO 'post_date' date not null default='0000-00-00' and there is so much confusing information when I do google searches on date/time functions. With my column being only 'date' (no time needed or wanted), I cannot insert a record. I have tried many different scenarios to do this. How can I insert the current date in this field at post creation time? 'yyyy-mm-dd' format.

Sorry nevermind. I got it figured out. $post_date = date("Y-m-d");
