Recently, I am developing a self-using blogging system, but I have some questions about the implementation of pagination.
The pagination I want is :
10 results per page
When user visits the home page(/), he/she could see the current page he/she is at(in this example is page one), and if there are more than 10 results, then he/she could be able to see the 'Next' Link.
If there are some results before this page, and there are also some results after this page, then this page should have 'Prev' and 'Next' Link and the current page number.
This thinking appeared when I was designing the algorithm about pagination:
If I want to implement this functionality, I need to know the total numbers of published posts.(If it is not published, it shouldn't be displayed), so maybe I need to write this SQL code :
SELECT COUNT(*) FROM post WHERE published IS NOT TRUE;
And I could pick the result above and the current page number the user is at to compute the pagination result.
But the question I want to ask is if there are many records , performance will be very terrible, how could I make this program more faster?
I see the pagination of a blog that has thousands of post and is built on top of WordPress is very fast, I want to know how could I archive this speed ?
Thanks a lot.
go through this sample PHP Pagination coding. Results won't be slow because of the LIMIT n,n+RecordsPerPage part of the mySQL query.

Let's say I'm making a blog app. I want to display the number of people who saw this specific post. Basically, if I have ten posts, I want to display the number of people saw each by opening it on the new Flutter page. I want to do this so people can basically see what is trending and click on that. Thanks!
You can set a counter at backend server api that how many times a blog post is called for fetching details. This can be a field for filter, sorting, display in app then.
I've noticed some websites that have a most viewed posts section. I am looking to add this functionality to the side bar.
How can you setup a method that determines how many posts have been selected by a user then add in the top 3 or so viewed posts?
For example here (towards the middle of the page in the sidebar, the most viewed): http://america.aljazeera.com/
Is there a bundle that incorporates this?
Or is there an easier method by using a count based on how many times a user clicks on a post?
No, I don't know anyBundle doing that.
To have the 3 most viewed article you need to add a field in your database which save how much the article is important.
You have severals ways of doing it, this is what comes to my mind:
First: You add an relation ViewedByWeek -> Post.
Foreach post, this entity keep how much it have been visited.
Everytime an user visit the page, you improve the number of visits of the post for the current week.
Then, you can find the most popular post in the week, in the month, in the year.
If you don't use anything related to the time, the information will not be changing much
I have a Drupal site which allows users to sign up and add their own content. I am trying to create something that emails users every week and shows them statistics like how many people viewed your content etc. I have turned on the statistics module and checked on count content views. I moved the popular content block into the correct region but it will not show me the number of hits only the most popular content pages. I would like to be able to show the number of hits. I was also wondering if there is a programatically way to print the number of page hits so I could do it that way. Thanks
Check out the statistics module's documentation. You can use statistics_get($nid) function to get total count of views of a node.
try Google Analytics Reports module. Statistics module has big impact on performance because of the huge db writes.
Theres a site i did that on the home page, i created kind of like a news box type
of thing which is what the client wanted...
the posts bit im using to limit the posts on the index page is
query_posts('posts_per_page=4');
Now, this limits my posts to "4" or whatever number i want etc, when the user clicks on the
"news" page button, it takes them to a page which has the full posts loop without the
query_posts('posts_per_page=4'); which essentially shows them all the posts.
Now the problem is that, this person is posting A LOT now and the page now has a bunch of posts one after the other.
Is there a way to limit these to any number (that i choose) and show the rest of the posts on another page???
So essentially something that says
filter out 20 messages/excerpts for example, BUT after 20 show a "next" page or something like that?
is that possible? Because as it stands now, by years end this ONE page will have hundreds of posts.
ive looked around but not sure exactly what im looking for. This one came close (here on SO)
Wordpress loop show limit posts
And although its similar, i need a way to limit the posts on the page AND continue them on another page so that one page doesnt hold ALL the posts.
Thanks in advanced.
The homepage is controlled by index.php or a template file used by a page which you can set up to be your homepage at Settings > Reading.
You must check your index.php file or the template file used the page from the homepage.
If your queries in the code are not including any "posts per page" arguments, you can control this numbers from Settings > Reading.
There is also a plugin which can help you:
http://wordpress.org/extend/plugins/custom-post-limits/
Now, clicking on news page, you must check if that is a page or a category listing?
If it's a page, then it is handled by page.php or an attached/used template for it. Again, the code is important, how the queries are written. It it's a category listing, then the category.php is handling that page.
Pay attention for the template files are using each every page/post and learn this: http://codex.wordpress.org/Class_Reference/WP_Query
Good luck! :)

In the settings you can set a default max limit of how many posts per page.
I have an ASP.NET application where View.aspx page will display the details of each products in a shopping cart.The page displays dynamic data(Ex: For each product id,the content will be different).Now i want to track the unique page views of each product.What are the best solutions to approach this problem ? I am already using google analytics.But i wanna custom solution/code for my web app,so that i can know how many hits came for each product
I have create a Statistical database, and I create a table, that have the product id, and the total views, for each product.
So every time a product is view by a user, I find in the table, this product line-id, and I am updating this values.
I think that is sound and it is simple.
How ever this is the base idea, you can improve it by your ideas.
http://www.google.com/analytics/ Set up each product with its on URL, or write it in the tracker dynamically. Also this has nothing to do with programming.
