Trying to achieve WP Pagination with only Prev and Next buttons - php

Question

I'm trying to modify my code for pagination in such a way that it only displays the Prev and Next buttons with no pages in the middle. This is proving to be kind of hard because paginate_links function doesn't have many options in terms of arguments which I can pass to disable the pages from being displayed.
Also using next_posts_link() and previous_posts_link() functions doesn't really help because that links to mydomain.com/page/2 whereas my default homepage is something like this mydomain.com/?fp_type=hot (to display particular kind of custom posts)
This is my pagination code
<?php
global $wp_query;
global $wp_rewrite;
if( is_search() ){
if( (int) get_query_var('page') > 0 ){
$current = get_query_var('page');
}else{
if( (int) get_query_var('paged') > 0 ){
$current = get_query_var('paged');
}else{
$current = 1;
}
}
$wp_query = new WP_Query('paged='. $current . '&s='.get_query_var('s') );
$pagination = array(
'base' => #add_query_arg( 'paged' , '%#%' ),
'format' => '',
'total' => $wp_query -> max_num_pages,
'current' => $current,
'show_all' => false,
'prev_next'=> true,
'prev_text'=> __('« Previous','cosmotheme'),
'next_text'=> __('Next »','cosmotheme'),
'type' => 'array'
);
if( $wp_rewrite->using_permalinks() ){
$pagination['base'] = user_trailingslashit( trailingslashit( remove_query_arg( 'search', remove_query_arg( 's', get_pagenum_link( 1 ) ) ) ) . 'page/%#%/', 'paged' );
}
if( !empty($wp_query->query_vars['s'] ) ){
$pagination['add_args'] = array( 's' => urlencode( get_query_var( 's' ) ) );
}
$pgn = paginate_links( $pagination );
if( !empty( $pgn ) ){
echo '<div class="pag">';
echo '<ul class="b_pag center p_b">';
if( $current == 1 ){
$current--;
}
foreach($pgn as $k => $link){
print '<li>' . str_replace("'",'"',$link) . '</li>';
}
echo '</ul>';
echo '</div>';
}
}else{
$wp_query->query_vars['paged'] > 1 ? $current = $wp_query->query_vars['paged'] : $current = 1;
$pagination = array(
'base' => #add_query_arg('paged','%#%'),
'format' => '',
'total' => $wp_query->max_num_pages,
'current' => $current,
'show_all' => false,
'type' => 'array'
);
if( $wp_rewrite->using_permalinks() ){
$pagination['base'] = user_trailingslashit( trailingslashit( remove_query_arg( 'fp_type' , remove_query_arg( 'type' , remove_query_arg( 's', get_pagenum_link( 1 ) ) ) ) ) . 'page/%#%/', 'paged' );
}
if( !empty($wp_query->query_vars['s'] ) ){
$pagination['add_args'] = array( 's' => urlencode( get_query_var( 's' ) ) );
}
if( !empty( $wp_query->query_vars['type'] ) ){
$pagination['add_args'] = array( 'type' => get_query_var( 'type' ) );
}
if( !empty( $wp_query->query_vars['fp_type'] ) ){
$pagination['add_args'] = array( 'fp_type' => get_query_var( 'fp_type' ) );
}
$pgn = paginate_links( $pagination );
if( $current == 1 ){
$current--;
}
if(!empty($pgn)){
echo '<div class="pag">';
echo '<ul class="b_pag center p_b">';
foreach($pgn as $k => $link){
print '<li>' . str_replace( "'" , '"' , $link ) . '</li>';
}
echo '</ul>';
echo '</div>';
}
} ?>

Add this code to that page where you want to show the post.
<?php
$page = (get_query_var('paged')) ? get_query_var('paged') : 1;
$args = array(
'cat' => '7',
'post_type' => 'post',
'posts_per_page' => 10,
'paged' => $page,
);
query_posts($args);?>
add below code after the post code:
<?php while ( have_posts() ) : the_post(); ?>
<div>
<ul>
<li>
<?php the_content(); ?>
</li>
</ul>
</div>
<?php endwhile; // end of the loop. ?>
<div class="navigation"><p><?php posts_nav_link(); ?></p></div>
