I had got the ans.
First you have to add following code in your function.php to call ajax in your template**
add_action( 'wp_ajax_demo-pagination-load-posts', 'cvf_demo_pagination_load_posts' );
add_action( 'wp_ajax_nopriv_demo-pagination-load-posts', 'cvf_demo_pagination_load_posts' );
function cvf_demo_pagination_load_posts() {
global $wpdb;
// Set default variables
$msg = '';
if(isset($_POST['page'])){
// Sanitize the received page
$page = sanitize_text_field($_POST['page']);
$cur_page = $page;
$page -= 1;
// Set the number of results to display
$per_page = 3;
$previous_btn = true;
$next_btn = true;
$first_btn = true;
$last_btn = true;
$start = $page * $per_page;
// Set the table where we will be querying data
$table_name = $wpdb->prefix . "posts";
// Query the necessary posts
$all_blog_posts = $wpdb->get_results($wpdb->prepare("
SELECT * FROM " . $table_name . " WHERE post_type="post" AND post_status="publish" ORDER BY post_date DESC LIMIT %d, %d", $start, $per_page ) );
// At the same time, count the number of queried posts
$count = $wpdb->get_var($wpdb->prepare("
SELECT COUNT(ID) FROM " . $table_name . " WHERE post_type="post" AND post_status="publish"", array() ) );
/**
* Use WP_Query:
*
$all_blog_posts = new WP_Query(
array(
'post_type' => 'post',
'post_status ' => 'publish',
'orderby' => 'post_date',
'order' => 'DESC',
'posts_per_page' => $per_page,
'offset' => $start
)
);
$count = new WP_Query(
array(
'post_type' => 'post',
'post_status ' => 'publish',
'posts_per_page' => -1
)
);
*/
// Loop into all the posts
foreach($all_blog_posts as $key => $post):
// Set the desired output into a variable
$msg .= '
<div class = "col-md-12">
<h2><a href="' . get_permalink($post->ID) . '">' . $post->post_title . '</a></h2>
<p>' . $post->post_excerpt . '</p>
<p>' . $post->post_content . '</p>
</div>';
endforeach;
// Optional, wrap the output into a container
$msg = "<div class="cvf-universal-content">" . $msg . "</div><br class="clear" />";
// This is where the magic happens
$no_of_paginations = ceil($count / $per_page);
if ($cur_page >= 7) {
$start_loop = $cur_page - 3;
if ($no_of_paginations > $cur_page + 3)
$end_loop = $cur_page + 3;
else if ($cur_page <= $no_of_paginations && $cur_page > $no_of_paginations - 6) {
$start_loop = $no_of_paginations - 6;
$end_loop = $no_of_paginations;
} else {
$end_loop = $no_of_paginations;
}
} else {
$start_loop = 1;
if ($no_of_paginations > 7)
$end_loop = 7;
else
$end_loop = $no_of_paginations;
}
// Pagination Buttons logic
$pag_container .= "
<div class="cvf-universal-pagination">
<ul>";
if ($first_btn && $cur_page > 1) {
$pag_container .= "<li p='1' class="active">First</li>";
} else if ($first_btn) {
$pag_container .= "<li p='1' class="inactive">First</li>";
}
if ($previous_btn && $cur_page > 1) {
$pre = $cur_page - 1;
$pag_container .= "<li p='$pre' class="active">Previous</li>";
} else if ($previous_btn) {
$pag_container .= "<li class="inactive">Previous</li>";
}
for ($i = $start_loop; $i <= $end_loop; $i++) {
if ($cur_page == $i)
$pag_container .= "<li p='$i' class="selected" >{$i}</li>";
else
$pag_container .= "<li p='$i' class="active">{$i}</li>";
}
if ($next_btn && $cur_page < $no_of_paginations) {
$nex = $cur_page + 1;
$pag_container .= "<li p='$nex' class="active">Next</li>";
} else if ($next_btn) {
$pag_container .= "<li class="inactive">Next</li>";
}
if ($last_btn && $cur_page < $no_of_paginations) {
$pag_container .= "<li p='$no_of_paginations' class="active">Last</li>";
} else if ($last_btn) {
$pag_container .= "<li p='$no_of_paginations' class="inactive">Last</li>";
}
$pag_container = $pag_container . "
</ul>
</div>";
// We echo the final output
echo
'<div class = "cvf-pagination-content">' . $msg . '</div>' .
'<div class = "cvf-pagination-nav">' . $pag_container . '</div>';
}
// Always exit to avoid further execution
exit();}
Now add this following code where you want to display your post.(like,index.php,home.php,etc..)
<div class="col-md-12 content">
<div class = "inner-box content no-right-margin darkviolet">
<script type="text/javascript">
jQuery(document).ready(function($) {
// This is required for AJAX to work on our page
var ajaxurl="<?php echo admin_url("admin-ajax.php'); ?>';
function cvf_load_all_posts(page){
// Start the transition
$(".cvf_pag_loading").fadeIn().css('background','#ccc');
// Data to receive from our server
// the value in 'action' is the key that will be identified by the 'wp_ajax_' hook
var data = {
page: page,
action: "demo-pagination-load-posts"
};
// Send the data
$.post(ajaxurl, data, function(response) {
// If successful Append the data into our html container
$(".cvf_universal_container").append(response);
// End the transition
$(".cvf_pag_loading").css({'background':'none', 'transition':'all 1s ease-out'});
});
}
// Load page 1 as the default
cvf_load_all_posts(1);
// Handle the clicks
$('.cvf_universal_container .cvf-universal-pagination li.active').live('click',function(){
var page = $(this).attr('p');
cvf_load_all_posts(page);
});
});
</script>
<div class = "cvf_pag_loading">
<div class = "cvf_universal_container">
<div class="cvf-universal-content"></div>
</div>
</div>
</div>
</div>
And at the last put this code into your style.css
.cvf_pag_loading {padding: 20px;}
.cvf-universal-pagination ul {margin: 0; padding: 0;}
.cvf-universal-pagination ul li {display: inline; margin: 3px; padding: 4px 8px; background: #FFF; color: black; }
.cvf-universal-pagination ul li.active:hover {cursor: pointer; background: #1E8CBE; color: white; }
.cvf-universal-pagination ul li.inactive {background: #7E7E7E;}
.cvf-universal-pagination ul li.selected {background: #1E8CBE; color: white;}
At the last you will see like this.
