Unable to change the active pagination button as it refreshes using php

I am trying to change the active pagination button when I click on it but it refreshes and remains the same as I get data after refresh. Here is the code:
<?php
for ($page=1;$page<=$number_of_pages;$page++) {
?>
<li class="page-item"><a class="page-link" href="view_videos.php?page=<?php echo $page;?>"><?php echo $page; ?></a></li>
<?php
}
?>
I will be getting urls as:
domain.com/hello.php?page=1
domain.com/hello.php?page=2
When I click on the second button the url changes to domain.com/hello.php?page=2 then I want change the background of second button color as active but due to page refresh its not becoming active.
Here is a screenshot of my navigation bar

Very simple:
Get the page_id like this:
$page_id = isset($_GET['page']) ? $_GET['page'] : false;
Now you have the number of the current page you are on
Then inside the loop, you could do another check like this:
<li class="page-item<?php echo ($page_id == $page) ? ' my-background' : '' ?>"><a class="page-link" href="view_videos.php?page=<?php echo $page;?>"><?php echo $page; ?></a></li>
Then you could do this in your .css-file:
.my-background {
background-color: #FF0000; /* Maybe add "!important" if necessary */
}

You have to get the page number from the URL after the page loads, and check it against each page indicator to see if it is the active one. Then you can add a class active, and style that in your CSS.
So you can try this:
<?php
for ($page = 1; $page <= $number_of_pages; $page++) {
if ($page === $_GET["page"]) {
$active = " active";
} else {
$active = "";
}
?>
<li class="page-item">
<a class="page-link <?= $active ?>" href="view_videos.php?page=<?= $page ?>"><?= $page ?></a>
</li>
<?php
}
?>
Note: <?= $foo ?> is the same as <?php echo $foo ?> manual

how to make a dynamic sidebar active on a clicking

I'm creating dynamic menu. I wanted to highlight the menu once it is selected.
We use php. just need to figure out how to append the class active to the current page. Can anyone help me with this?
<div id="sidebar-wrapper" class="sidebar-toggle">
<ul class="sidebar-nav">
<?php
$i=1;
if(count($shipments) > 0)
{
foreach($shipments as $row)
{
$shipment_id = $row['id'];
$containerdest = $row['no']."-".$row['destination'];
?>
<li id="shipment<?php echo $shipment_id; ?>"><?php echo $containerdest; ?>
</li>
<?php $i++;
}
} ?>
<li>
Logout
</li>
</ul>
</div>
</div>

Change your html line with below line
<li id="shipment<?php echo $shipment_id; ?>" class="menu"><a href="<?php echo ite_url("users/get_details/$shipment_id");?>" shipmentid="<?php echo $shipment_id; ?>" ><?php echo $containerdest; ?></a>
And write javascript code as below (assuming you have included jquery library file)
<script>
$(document).ready(function(){
var url = location.pathname;
var arr = mystr.split("/");
var id = arr[2];
$(#shipment'+id).attr('shipmentid');
$('.menu').removeClass('active'); //this will remove all active class after page loading
$('#shipment'+id).addClass('active'); // this will append active class to the current clicked menu
});
</script>

Wordpress AJAX Load More Button

I just found this script https://github.com/tokmak/wp-load-more-ajax and I wanted to add it into my template.. All good, I added the script from functions.php into my template functions.php, copied the js file in my template folder and added that line from your_template.php into my template page where my posts are shown, the button appear but it doesnt work..
I have every file loaded, I checked but still it does nothing..
<?php if (have_posts()) : while ( have_posts() ) : the_post(); ?>
<div class="post-box">
<div style="float:left; margin-bottom: 10px; padding-right:20px;"> <?php if ( has_post_thumbnail() ) { echo get_the_post_thumbnail($post->ID); } else { echo my_post_thumbnail_html(); } ?> </div>
<div class="post-title"> <?php the_title(); ?> </div>
<div class="post-content"> <?php excerpt(10); ?> </div>
<br clear="all" />
</div>
<?php endwhile; ?>
<a class="load_more" data-nonce="<?php echo wp_create_nonce('load_posts') ?>" href="javascript:;">Load more</a>
<?php else : ?>
<p><?php _e('Sorry, no posts matched your criteria.'); ?></p>
<?php endif; wp_reset_query(); ?>
This is my code.. I dont know what to do..

You must have a loaded content template.
Once, you create a template and add new page with this template. Your page link example: http://localhost.dev/?page_id=1453
This template containt only post loop. You can develop this template with $_GET params(numberposts, category etc.)
function loadMore(e, numberposts) {
$('.show-more', e).text('Loading...');
$('<div>').load('<?php echo get_bloginfo('template_url'); ?>/get_loop_template.php?s=' + numberposts, function(r) {
$('.list-articles .btn-getmore').remove();
$('.list-articles').append(r);
});
}
This function get your posts, remove current "getmore-buton" than insert posts and add new "getmore-buton".

Bring a WordPress post dynamically

I've been trying to make this feature work for many days now and it's driving me nuts!
I have a single page theme in WP and in one of them there is a div on the left with a list of the posts in the site and on the right, a div that should display the content of the clicked post.
I found this question and followed up the linked tutorial and was partially successful.
I managed to bring the content dinamically, and all I want is being displayed but it seems the order of the tasks are wrong. Heres how it's acting:
I click on the link.
the current content goes away.
the loading span appears correctely.
the SAME content fades in.
after 1 second or so the current content is replaced with the new content and the address bar does not change at all.
Here's the code I have:
atracoes.js
$(document).ready(function() {
var hash = window.location.hash.substr(1);
var href = $('.controle nav li a').each(function(){
var href = $(this).attr('href');
if(hash==href.substr(0,href)){
var aCarregar = hash+'.html #atr-conteudo';
$('#atr-conteudo').load(aCarregar)
}
});
$('.controle nav li a').click(function() {
var aCarregar = $(this).attr('href')+' #atr-conteudo';
$('#atr-conteudo').hide('fast',carregarConteudo);
$('#carregando').remove();
$('#atracoes').append('<span id="carregando">Carregando...</span>');
$('#carregando').fadeIn('normal');
window.location.hash = $(this).attr('href').substr(0,$(this).attr('href'));
function carregarConteudo () {
$('#atr-conteudo').load(aCarregar,'',mostrarNovoConteudo());
}
function mostrarNovoConteudo () {
$('#atr-conteudo').show('normal',esconderCarregando());
}
function esconderCarregando () {
$('#carregando').fadeOut('normal');
}
return false;
});
});
index.php (the dynamic content part)
<div class="main" id="atracoes">
<div class="controle">
<nav>
<?php
$args = array( 'posts_per_page' => 20);
$myposts = get_posts( $args );
foreach ( $myposts as $post ) : setup_postdata( $post ); ?>
<li>
<?php the_title(); ?>
</li>
<?php endforeach;
wp_reset_postdata();?>
</nav>
</div>
<div id="atr-conteudo">
<?php the_post_thumbnail(); ?>
<div id="atr-texto">
<h2><?php the_title(); ?></h2>
<?php the_content(); ?>
</div>
</div>
</div>
single.php (the part I'm plucking with ajax)
<!-- article -->
<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
<!-- post thumbnail -->
<?php if ( has_post_thumbnail()) : // Check if Thumbnail exists ?>
<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>">
<?php the_post_thumbnail(); // Fullsize image for the single post ?>
</a>
<?php endif; ?>
<!-- /post thumbnail -->
<div id="atr-texto">
<!-- post title -->
<h1>
<?php the_title(); ?>
</h1>
<!-- /post title -->
<?php the_content(); // Dynamic Content ?>
<?php edit_post_link(); // Always handy to have Edit Post Links available ?>
</div>
</article>

You're calling the functions before you pass them to jQuery to execute, instead of allowing jQuery to execute them:
function carregarConteudo () {
$('#atr-conteudo').load(aCarregar,'',mostrarNovoConteudo);
}
function mostrarNovoConteudo () {
$('#atr-conteudo').show('normal',esconderCarregando);
}
(Notice they no longer have () after the function names)

call jquery event after getting the current page id from php

My knowledge in Javascript is not that good and I used a sample code I got from the web and need help in that.
I have a jquery multi level menu and I have a problem to open one section of the menu after getting the current viewed page id from the php (wordpress).
I'm using wordpress custom post type (taxonomy) to create category and pages, below is my code.
Javascript:
<script type="text/javascript">
$(function() {
var menu_ul = $('.aside-menu > li > ul'),
menu_a = $('.aside-menu > li > a');
menu_ul.hide();
menu_a.click(function(e) {
e.preventDefault();
if(!$(this).hasClass('active')) {
menu_a.removeClass('active');
menu_ul.filter(':visible').slideUp('normal');
$(this).addClass('active').next().stop(true,true).slideDown('normal');
} else {
$(this).removeClass('active');
$(this).next().stop(true,true).slideUp('normal');
}
});
});
</script>
Html and PHP:
<ul class="aside-menu">
<?php $parents = get_terms('product_category',array('parent' => 0, 'hide_empty' => false)); ?>
<?php foreach($parents as $parent): ?>
<li><?php echo $parent->name; ?>
<ul>
<?php $children = get_terms('product_category',array('parent' => $parent->term_id, 'order' => 'ASC')); ?>
<?php foreach($children as $child): ?>
<li><?php echo $child->name; ?></li>
<?php endforeach; ?>
</ul>
</li>
<?php endforeach; ?>
</ul>
I know how to get the current page by php (wordpress)
<?php echo get_queried_object()->parent == $parent->term_id ? '' : '' ?>
Know what should i do in order to tell javascript to open the section of the menu?
Thanks in advance.

You will:
<?php if(get_queried_object()->parent == $parent->term_id): ?>
<script>
yourJavaScriptFunction(<?php echo $parent->term_id; ?>);
</script>
<?php endif; ?>
Update: In some place of your file...
<script>
function yourJavaScriptFunction(data) {
alert("This data is from Ajax: " + data);
}
</script>
