I'm new on wordpress and I'm trying to create my first website, I have an index.php page with about link, which will get about author content from created page (post) inside wordpress dashboard with name about. I'm using magnific popup plugin for poups.. I have about.php which includes content of about page like this
about.php
<?php
$pageid = 2; // 2 is the id of about page/post
$about = get_post($pageid);
?>
<div id="custom-content" class="white-popup-block" style="max-width:600px; margin: 20px auto;">
<h3><?php echo $about->post_title; ?></h3>
<style>
#custom-content img {max-width: 100%;margin-bottom: 10px;}
</style>
<div class="image-container pull-left">
<img src="<?php echo get_field( "image", $pageid ); ?>">
</div>
<h4><?php echo get_field( "brief", $pageid ); ?></h4>
<p>
<?php echo get_field( "brief_lines", $pageid ); ?>
</p>
<div class="about-content">
<?php echo $about->post_content; ?>
</div>
</div>
index.php
<a href="<?php echo get_template_directory_uri(); ?>/about.php" class="morelink pull-left text-ajax-popup">read more</a>
footer.php
$('.text-ajax-popup').magnificPopup({
type: 'ajax',
alignTop: true,
overflowY: 'scroll'
});
after click on the link I got this error
Fatal error: Call to undefined function get_post()
Is there files could I include inside about.php ? what is the problem ?
