WP: 5. Guide to Implement Next Previous Post Navigation in WP

 

Today I ran into a problem, I need to implement to post previous and next navigation and found this solution.

And nonetheless, It's better to fix the thing with some bunch of code rather than uploading one more bulky plugin on your website that will end up making your site heavy.

Just follow the steps below and avoid heading up into any malicious or bulky plugin for this particular problem from now on forever.

Step 1: Go ahead and paste the following code in your active theme's single.php

//To return the URL of the previous page, use the following php code:
$prev = get_permalink(get_adjacent_post(false,'',false));
//To return the URL of the next page, use the following php code:
$next = get_permalink(get_adjacent_post(false,'',true));

//To use them, simply echo the variables $prev and $next where you need them.
<a href="<?php echo $prev; ?>">Previous Post</a> and the 
<a href="<?php echo $next; ?>">Next Post</a>

//What if there isn’t a previous or next post?
//Since our functions will automatically return either the adjacent post’s URL if there is one or the current post’s own URL if you’re on the first or last post. Use the following code to make it conditional whether to display the previous or next post link:
<?php $prev = get_permalink(get_adjacent_post(false,'',false)); 
    if ($prev != get_permalink()) { ?>
        <a href="<?php echo $prev; ?>">Previous Post Only Displaying If Available</a>
<?php } ?>

//There you have it — hope it saved you a headache. 

Now Cheers !😊

C: 10. Array

 An array is defined as the collection of similar type of data items stored at contiguous memory locations. For example, if we want to store the marks of a student in 6 subjects, then we don't need to define different variables for the marks in the different subject. Instead of that, we can define an array which can store the marks in each subject at the contiguous memory locations. An array index starts with 0. Syntax:- data_type array_name[array_size];   int marks[5];     Example:- #include<stdio.h>   int main(){       int i=0;     int marks[5];//declaration of array        marks[0]=80;//initialization of array     marks[1]=60;     marks[2]=70;     marks[3]=85;     marks[4]=75;     //traversal of array     for(i=0;i<5;i++){       printf("%d \n",marks[i]);   ...

Py: 2. Python Fundamentals

 Variable:-  Variable is a name that is used to refer to memory location. In Python, we don't need to specify the type of variable because Python is smart enough to get variable type.  Variable names can be any length can have uppercase, lowercase (A to Z, a to z), the digit (0-9), and underscore character(_). Syntax:-  num= 345 name= "mohit" Variable Types:- Number (Int, Float) Sting Boolean Get the Type of the variable:- x = 5 y = "John" print(type(x)) print(type(y)) Output:-  <class 'int'> <class 'str'> Operators:-  The operator can be defined as a symbol which is responsible for a particular operation between two operands. Python provides a variety of operators, which are described as follows. Arithmetic Operators:-  Assume variable a holds 10 and variable b holds 20, then − + Addition Adds values on either side of the operator. a + b = 30 - Subtraction Subtracts right hand operand from left hand operand. a – b = -10 * Multiplicat...
