Can you provide more information? how is anyone supposed to figure out what to do with the title and code you provided?

A more detailed description of the problem, what you are trying to accomplish, etc.. will likely get you more help.

sorry, i included it on comment, my problem is i cannot get the article_id to store it on com_art_id, the articles_id is already showing on url bar, i have no idea how to place it on com_art_id, can i use GET function? show me how to do it, im realy new at php

Ok, i see it in your code as commented...

Refer to this page in the online PHP manual: http://www.php.net/manual/en/reserved.variables.get.php

If you want to get the query string, use $_GET

Say your URL is articlespage.php?id=1, your code to get that query string parameter called "id" would be... $_GET["id"]

Therefore... $com_art_id = $_GET["id"]; should work.

You should consider performing some check(s) prior to assuming that the value in the query string is going to be a value you expect.

$com_art_id = $_GET["id"];

this doesnt work, also please tell me why year is always wrong and all months and days are 1-14, it always saved 0 as com_art_id

$comment_date = date('d-m-y');

Should be:

$comment_date = date('Y-m-d');
$comment_date = date('Y-m-d');

this solved the date, i still cant put article_id as the value of com_art_id

$com_art_id never gets a value.

how to place article id on a user comment so that if user submitted the comment, it will have the article id, then we can show all comments for specific article

$com_art_id = $_GET["id"]
solved my problem, thank you sirs
