I've been looking in google and couldn't find a tutorial. I would like that when the user clicks on a image in a wordpress post, a modal opens and displays the image with full size. I don't have an issue on how to make a modal, I'm just not sure how to fetch the image and put it in the modal. I don't want to use a plugin, I want to undertand how it works. If you have a good tutorial on how to do that, or if you feel like explaining it, please do! Thanks!

You can create a JS onclick function ex openModal() that submits current post info as arguments:
index.php file
if ( have_posts() ) : while ( have_posts() ) : the_post();
if ( has_post_thumbnail() ) :
$thumbnailBgImg = wp_get_attachment_image_src(get_post_thumbnail_id($post->ID), 'medium');
<!-- THUMBNAIL SECTION -->
<div class="post" onclick="openModal('<?php echo $thumbnailBgImg[0] ?>', '<?php the_title(); ?>', '<?php echo $post->ID ?>', '<?php echo the_content() ?>')" >
<div class="post-thumbnail" id="post-thumbnail" style="background-image: url('<?php echo $thumbnailBgImg[0]; ?>');"></div>
<div class="post-content">
<h3 id="thumbnail-h3"><?php the_title(); ?></h3>
<p id="thumbnail-p"><?php the_content(); ?></p>
</div>
</div>
<!-- MODAL SECTION -->
<div id="myModal" class="modal">
<span class="close">×</span>
<div class="modal-box">
<img class="modal-content" id="modal-img">
</div>
<div id="caption">
<div class="caption-text">
<h3></h3>
<p></p>
</div>
<a></a>
</div>
</div>
endif; endwhile;
endif;
script.js file
// MODAL IMAGE
function openModal(URL, TITLE, ID, CAPTION){
var modal = document.getElementById('myModal')
var modalImg = document.getElementById("modal-img")
var caption = document.getElementById("caption")
var captionH3 = caption.getElementsByTagName('h3')[0]
var captionA = caption.getElementsByTagName('a')[0]
var captionB = caption.getElementsByTagName('p')[0]
var span = document.getElementsByClassName("close")[0]
var newTitle = encodeURIComponent(TITLE.trim())
modal.style.display = "flex"
captionH3.innerHTML = TITLE
modalImg.src = URL
captionB.innerHTML = CAPTION
captionA.href = "mailto:[email protected]?Subject=" + newTitle
captionA.innerHTML = "Contact me"
span.onclick = function() {
modal.style.display = "none"
}
}
My result:
Hope it helps <3
