Retrieving The Most Viewed Post?


Recommended Posts

I am trying to retrieve the most viewed post (popular) but it is not working.

 

Is this syntax right?

 

 

// Retrieve the most viewed post

 

$q = " SELECT post_id ,title COUNT(title) AS most FROM posts GROUP BY title ORDER BY most DESC LIMIT 5";

$r = @mysqli_query($dbc, $q);

 

if($r) {

while($row = mysqli_fetch_array( $r, MYSQLI_ASSOC )) {

echo ' <p><a href="article.php?id='. $row['post_id']. '"> ' . $row['most']. ' </a> </p>';

}

===========================================

Thank you

That won't really work. What you do here is to count how many times a title occurs in the Database. That won't let you count number of view.

 

What you need to do is update the table record each time a post is queried. This query should only be used when a SINGLE POST is queried, hence, it's actually viewed. This query is run when you have a link like this:

 

- http://domain.com/?post_id=10

 

// Get value from GET array
$id = int_val($_GET['id']; // This will be post_id 10 if you use the link above

// Set queries
$q = "SELECT * FROM posts WHERE post_id = {$id} LIMIT 1";
$q .= "UPDATE posts set views=(views+1) WHERE id = {$id}"; // Notice .= here. This means it will be added to first string

// run both queries
$r = @mysqli_multi_query($dbc, $q);

 

When THAT is done, you can tweek your first query a little bit;

 

$q = "SELECT * FROM posts ORDER BY views DESC LIMIT 5";

 

That will give you 5 posts sorted by number of views

Thank you Antonio,

I have done the following but it is not working.

 

<?php

// Counting the views:

 

$p_id = intval($_GET['id']);// post id variable.

$q = "SELECT post_id, title FROM posts WHERE post_id ={$p_id} LIMIT 5";

$q .= "UPDATE posts SET views=(views+1) WHERE post_id = {$p_id}";

 

// run both queries

$r = @mysqli_multi_query($dbc, $q);

 

// If it ran OK :

if($r) {

while($row = mysqli_fetch_array( $r, MYSQLI_ASSOC )) {

echo ' <p>

<a href="article.php?id='. $row['post_id']. '"> ' . $row['title']. ' </a>

</p>';

}

} else {

echo 'There is no post at the moment!';

}

?>

Sorry Antonio.

I really got stuck. There is column named views

I have done a separate queries as you can see below

<article>
<h1>Most popular post  </h1>
<?php
// Get value from GET array
$p_id = intval($_GET['id']); // This will be post_id 10 if you use the link above
// Set queries
$q = "SELECT * FROM testposts WHERE post_id = {$p_id} LIMIT 1";
$q .= "UPDATE testposts SET views=(views+1) WHERE post_id = {$p_id}"; // Notice .= here. This means it will be added to first string
// run both queries
$r = @mysqli_multi_query($dbc, $q);
$q = "SELECT post_id, title, views FROM testposts ORDER BY views DESC LIMIT 4";
$r = @mysqli_query($dbc, $q);

// If it ran OK :
if($r) {
while($row = mysqli_fetch_array( $r, MYSQLI_ASSOC )) {

   echo ' <p>
 <a href="article.php?id='. $row['post_id']. '"> Latest:  ' . $row['title'].   ' </a>
   </p>';

 }
} else {
 echo 'There is no post at the moment!';
  }
?>
</article>

 

Thank you for trying to help me.

Counting the page views.

I am using this code:

// views counter:
$q = 'UPDATE posts SET `views` = `views`+1 WHERE post_id='.$_GET['id'];
$r = mysqli_query($dbc, $q);

to count the page views.

But I do not know if it is wright, although it is working.

What do you recommend me to do?

Thank you.

// views counter:
$q = 'UPDATE posts SET `views` = `views`+1 WHERE post_id='.$_GET['id'];
$r = mysqli_query($dbc, $q);

This code works fine and I have noticed that when the page is viewed the order of posts in the main page (view_posts.php) changes according to the last post viewed. Although mysql query sets the order by to date_added DESC.

The problem is that the last post viewed or displayed goes first in list.

How can I fix this issue ?

Thank you.

Please post both your scripts. The one displaying single posts, and the one displaying the list.

 

I can't wrap my head around your explanation. Only thing might be the query for getting the list could need a second ORDER BY clause, something like maybe "ORDER BY views DESC, date_added DESC". (But I don't think your problem lies there)

Thank you.

The query for page which lists the posts:

$q = "SELECT post_id, views ,author,  title, content, DATE_FORMAT(date_added, '%M %d, %Y') AS posted FROM posts ORDER BY date_added DESC "; 

 

Single post:

 

// views counter:

$q = 'UPDATE posts SET `views` = `views`+1 WHERE post_id='.$_GET['id'];

$r = mysqli_query($dbc, $q);

 

$q = 'SELECT views, author, title  content, DATE_FORMAT(date_added, "%M %d, %Y") AS posted FROM  posts WHERE post_id=' . $_GET['id'];

So what you're saying is that you want to first get the top 5 most-viewed posts, and once you have those, order them in chronological order (i.e., oldest first), right?

 

If that's the case, then you need to essentially use a subquery to get what you want. I think the following link is relevant to your problem:
