Question

I want to develop a system where a user should be able to post the comments on the author published news.

I am very much confused about the Insert Statement that i should be using to store the user commenting system, i have two mysql table one is news and another is comments below is the screenshot of two tables.

news

comments

in the comments table i have defined a foreign key (new_id) , in which i want to store the value that is related to the particular news for example a news with id no. 7, how do i achieve this dynamic feat? how do i automatically relate it to the news when a user post the comment (nevertheless to say that the user will be giving the input from the form )?

EDIT : I want to use One news article on one page.

thank you

Well first off you need to know how you are going to view a news item? Is this going to have all news articles on one page and below each news article is a to post new comments? If so then each of these forms generated per news article should have the news ID in the form potentially as .

Example:

<p>News article 1.</p>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
   <input type="hidden" name="new_id" value="1"/>
   <textarea name="comments"></textarea>
   <input type="submit" name="submit" value="Post COmment"/>
</form>

<p>news article 2</p>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
   <input type="hidden" name="new_id" value="2"/>
   <textarea name="comments"></textarea>
   <input type="submit" name="submit" value="Post COmment"/>
</form>

Then on this page at the top you can check for whether or not user pressed submit button:

<?php
  if(isset($_POST['submit'])){
       //$_POST['new_id'] is news article id 
       //$_POST['comments'] is comments for this 
       //sql to store new_id = $_POST['new_id'] and comments = $_POST['comments']
  {

Alternatively:
Lets say on your home page you have links to each news article and you retrieve them on subsequent page using $_GET. So index.php displays news and getNews.php is where news is displayed. You could want to on index.php generate a link to getNews.php?id=

THis way on getNews.php you know which news article to get using $_GET[‘id’] and you can easily post comments to this using a similar technique to above, take $_GET[‘id’] and toss it into your form on getNews.php as hidden field.

Caution: be careful and sanitize your $_GET variable before using it.
