Calendar Admin-Ajax

It’s not online yet. I run it localhost.

Here’s the code that I use for my template.
I also don’t have permalinks enabled in the settings of the plugin so that I can GET the ?news_ondate.
I made this template because I wanted to show the users on what date and time the news was posted.
Is there an easier way to accomplish this or am I on the right track?
<?php dynamic_sidebar(‘Nieuws widgets’); ?> is a seperate widget space with the calendar widget in.

<?php
/*
Template Name: News
*/
session_start();
get_header(); ?>
<div id=”primary”>
<div id=”content” role=”main”>
<?php

$paged = ( get_query_var( ‘paged’ ) ) ? get_query_var( ‘paged’ ) : 1;
// $wp_query = new WP_Query( array ( ‘post_type’ => ‘news’, ‘posts_per_page’ => ‘5’, ‘paged’ => $paged ));

$sel = 0;
if(isset($_GET[‘news_ondate’]))
{

$periode = trim($_GET[‘news_ondate’]);

if(isset($_SESSION[‘hulpperiode’]))
{
if($periode <> $_SESSION[‘hulpperiode’])
$paged = 1;
}

$_SESSION[‘hulpperiode’] = $periode;
$jaar = substr($periode,0,4);
$maand = substr($periode,5,2);
$dag = substr($periode,8,2);

$wp_query = new WP_Query(array
( ‘post_type’ => ‘news’, ‘posts_per_page’ => ‘5’, ‘paged’ => $paged,
‘date_query’ => array(
array(
‘year’ => $jaar,
‘month’ => $maand,
‘day’ => $dag,
),
)
));

$sel = 1;

}
else
{
$wp_query = new WP_Query( array ( ‘post_type’ => ‘news’, ‘posts_per_page’ => ‘5’, ‘paged’ => $paged ));
}

print (“</BR>”);

if($sel == 1)
{
print “Berichten op $dag-$maand-$jaar”;
print (“</BR>”);print (“</BR>”);
}

while ($wp_query->have_posts()) : $wp_query->the_post();

print (“<table width=100%><tr><td width=100% class=\”nieuwstitel\”>”);the_title();print (“</td></tr>”);
print (“<tr><td class=\”nieuwsgepostop\”>Gepost op: “);the_time( ‘d/m/Y H:i’, ”); print (“</td></tr>”);
print (“<tr><td><hr></td></tr>”);
print (“<tr><td>”);the_content(); print (“</td></tr>”);
print (“<tr><td><BR></td></tr>”);

endwhile;

print (“</TABLE>”);?>

<?php if ($paged > 1)
{ ?>

<nav id=”nav-posts”>
<div class=”prev”><?php next_posts_link(‘« Vorige posts’); ?></div>
<div class=”next”><?php previous_posts_link(‘Nieuwere posts »’); ?></div>
</nav>

<?php
} else
{ ?>

<nav id=”nav-posts”>
<div class=”prev”><?php next_posts_link(‘« Vorige posts’); ?></div>
</nav>

<?php
}
wp_reset_postdata(); ?>

</div><!– #content –>
</div><!– #primary –>

<div id=”secondary” class=”widget-area” role=”complementary”>
<?php dynamic_sidebar(‘Nieuws widgets’); ?>
</div>

<?php //get_sidebar(”); ?>
<?php get_footer(); ?>

Is the coding so bad?
Besides from using a session instead of a coockie, which parts can be improved?
Actually all I want to do is add the date and time that a news item was made to the page.
When I enable permalinks in the settings of the news manager and add %postname% to it,
it goes to this URL: /postname/2014/02/07/ and shows the posts for that date.
But it didn’t load my template page so it doesn’t show the date and time that the news item was added nor the calendar widget.
I’m starting to think that there’s an easier way to accomplish all this,
even with permalinks enabled in the settings of the plugin.
Can you give me some help?

Thanks in advance.

Thanks for the info!
I created the pages like you said and everything is working fine now.
I enabled the permalinks in the plugin and referred it to the pagename where
I want to display the news. ( Or can I display the news on a page in a different way? )
Just one last question.
What if I want to display the news on more than one page?
How does this work as I can only fill in one word in the permalinks settings.
Sorry if these are obvious questions but when I search for it online I keep bumping into “Templates”
and that’s just what I’m trying to avoid.

Thanks for all the help!
Everything is working like it should be and my code looks much cleaner :)

Thanks again.
