I use this code to get the informations about a certain id
$sql = dbquery("SELECT * FROM `videos` WHERE `id` = ".$local_id." "); while($row = mysql_fetch_array($sql)) Perhaps two more queries would work .
select id,title from videos where id < $local_id order by id desc limit 1 select id,title from videos where id >$local_id order by id asc limit 1 Answer by Briar Silva

We create the next and previous button on the PHP website for a change row data like the next row from the current row and the previous row from the current row. ,All the data on the website is stored in the database.

Answer by Eduardo Kline
Here’s 2 different code snippets which enable you to link all posts assigned to any custom post type.,Its pretty easy to add next and previous nav links at the end of all your single posts. But what about adding them to all posts using one specific post type? ,As an example, you may have a portfolio where you want all single posts assigned to that specific portfolio post type linked together. And you may not want to link other post types to the posts assigned to this custom post type.,Single post navigation links are valuable because they link all your posts together. This increases page views and acts a bit like a sitemap which the search engines can follow.
add_action( 'genesis_entry_footer', 'wpsites_single_cpt_navigation' ); function wpsites_single_cpt_navigation() < if ( is_singular( 'portfolio' ) ) < echo''; echo''; > > Answer by Beau Richmond
Well since the filters for the singular next and previous links are applied differently see this ,How can I add a CSS Class to the previous_post_link output or just get the URL and create the HTML markup myself,You can use the more native function that is "below" the previous_/next_post_link();:, Business Learn more about hiring developers or posting ads with us
You can use the more native function that is "below" the previous_/next_post_link(); :
# get_adjacent_post( $in_same_cat = false, $excluded_categories = '', $previous = true ) $next_post_obj = get_adjacent_post( '', '', false ); $next_post_ID = isset( $next_post_obj->ID ) ? $next_post_obj->ID : ''; $next_post_link = get_permalink( $next_post_ID ); $next_post_title = '»'; // equals "»" ?> " rel="next" pagination-link pagination-next">
Next and Previous buttons in PHP with MYSQL database
It is very beneficial to manipulate the data on the website, by which users also visit other pages of the website. If you have to change the next and previous data row of the MYSQL database by buttons, then you have to create two buttons. Next and previous buttons can be easily created by PHP and MYSQL, so that if a user wants to see the next row data from the same data page, then click on the Next button and if the user wants to get previous page data, then click on the previous button. The Next and Previous buttons are created using HTML and CSS, with functionality created by the PHP and MYSQL database.
i.e- You may have seen on the blog website or other websites that there is a next button for the next post or page (Next row data) and a previous button for the previous post or page (Previous row data).
We create the next and previous buttons on the PHP website for a change row data like the next row from the current row and the previous row from the current row.
How to create Next and Previous buttons in PHP –
We have discussed above the functional part. Here, we are going to implement that process.
To create the next and previous buttons on a blog website or another website, HTML table, etc you have to manage data in the database. Here, we will use the example of a simple website and will create the next and previous buttons steps-wise using PHP and MYSQL.
1. Create MYSQL Database table–
All the data on the website is stored in the database. Databases can be created by any name. Create a table in the database whose data will manipulate the rows with the Next and Previous buttons.
CREATE TABLE `webdata` ( `id` int(11) NOT NULL, `title` text NOT NULL, `content` longtext NOT NULL );
In the table above, we have created three simple columns.
Id – Unique id for each row.
Title – Title of the website page or blog post ( Column 2 )
Content – Body content about page or blog post content (column 3 )
Let's insert some data into the MYSQL database table -
INSERT INTO `webdata` (`id`, `title`, `content`) VALUES (1, 'Web page title 1 ', 'Web page content 1 '), (2, 'Web page title 2', 'Web page content 2 '), (3, 'title 3', 'content 3'), (4, 'title 4', 'content 4 '), (5, 'page 5', 'body content 5'), (6, 'page 6 ', 'body content 6 '), (7, 'web page 7', 'web page content 7'), (8, 'web page title 8', 'web page content 8'), (10, 'Website page 10', 'website page content body 10');
2. Create a connection PHP file –
As you know that the connection file is used to create a connection between the MYSQL database and PHP pages. Let’s create a connection file name as config.php
3. Create main page (Index page)
After creating the connection file, we create the main page. The main pages of the website are known as the index page. Here we creating an example of a PHP blog website . In the blog website, first of all, the blog posts or the rows data are fetched and displayed listwise by a while loop . After that, the Next and Previous buttons are created on the show page. Let's fetch and display the MYSQL database table rows data listwise using PHP and MYSQL query.
On this page, we have only fetched and displayed the data. If you notice, we have created links through show.php and id. When a user clicks on any title, the data related to that title will be displayed on the show.php page. Fetch and display unique data by ID. Next and previous buttons are created using the ID .
4. Fetch and display data related to the web page title.
When a user clicks on a title, all the data related to that title will be displayed on the show page. Each page title (row) contains a unique id. The data is displayed using a unique title (row id). We will create the next and previous button below the title and content.
Next Button - We use current page id and create a condition for the next page or next row data.
SELECT * FROM table_name WHERE id>$id order by id ASC
In the query above, you can see that we are selecting data from the database with a condition.
Condition WHERE id>$id –
Meaning – The current page id is less than the selecting id. In simple words, we are fetching row id that is greater than the current page id.
Selecting_id>current_id
Order by ASC – Order should be ascending.
Previous Button- The previous button mechanism is the opposite of the next button mechanism.
SELECT * FROM table_name WHERE id
In the query above, you can see that we are selecting data from the database with a condition.
Condition WHERE id
Meaning – The current page id is greater than the selecting id. In simple words, we are fetching row id that is less than the current page id.
Selecting_id
Order by ASC – Order should be Descending.
?>
$id order by id ASC"); if($row = mysqli_fetch_array($next)) < echo ''; > // Previous button $previous= mysqli_query($mysqli, "SELECT * FROM webdata WHERE id<$id order by id DESC"); if($row = mysqli_fetch_array($previous)) < echo ''; > ?>
- GET id by PHP GET variable and save in a variable.
- Fetch and display data by that id variable.
- Create two buttons.
- PHP If condition helps to get single next and previous row data.
- If the row is last then the next button disappears (Hide) because there is no next row.
- If the row is first then the previous button disappears (Hide) because there is no previous row.
In the code above, we have used CSS class for the buttons.
Use CSS stylesheets and execute the code.
