This is going to be a detailed answer to my problem to help anyone who might face the same problem, it will cover everything in steps for a WordPress newbie, like me! :D
As mentioned in my Question, my problem is that I want to display 2 posts in my index.php and make a separate blog page contains the whole posts.
The Most Detailed Solution:
1) Go to your index.php and use the normal posts loop:
<?php
// The Loop
if ( have_posts() ) {
while ( have_posts() ) {
the_post();
//
// Post Content here
//
} // end while
} // end if
?>
2) From WP Dashboard, go to Settings then Reading and change the Blog pages show at most value to 2 posts Or whatever number of posts you want.
Now, we've done the first step and show only a specific number of posts in our index.php, let's continue the steps to display the whole posts in our blog page.
3) Create a PHP Page called page-blog.php.
Notice: if you don't have a page.php you have to create it, for more information about how to create a custom PHP Page, I recommend @Adam's answer here.
4) Go to your WP Dashboard and create a new page called blog.
5) In your page-blog.php you need to add this snippet:
// Posts Query
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$args = array('posts_per_page' => 6, 'paged' => $paged );
query_posts($args);
// The Loop
if ( have_posts() ) {
while ( have_posts() ) {
the_post();
//
// Post Content here
//
} // end while
} else {
echo "Sorry, There is no posts to be displayed";
} // end if
?>
Notice: We used the same loop as we did before in index.php, only the new 2 lines of codes which above the loop is the new different thing here in our page-blog.php page
6) I set the posts_per_page to 6 because it is my blog page and I want to display more posts there. Set its value to whatever number you want, it depends on you
7) BOOM, it works and you did what you wanted, just like me!!
This problem seemed VERY COMPLICATED for me, but when I searched and read more information about this, I found that it is a VERY EASY to solve problem, and I hope this answer help you if you faced it!
