Get the featured image url of clicked post - php

Question

How can I display the featured image of a post in a modal along with it's content.
With the help of a few online threads on similar issues, I tried this:
<?php
if ( has_post_thumbnail()) {
echo '<a href="' . get_permalink($post->ID) . '" >';
the_post_thumbnail('my_feature_image', array( 'class' => "someName" ));
echo '</a>';
}
?>
Which unfortunately returns the same featured image for all posts.
On the same header.php where the modal is found, the following is there (above the modal divs):
//on the homepage... check for the post URL...
//do we have a custom permalink incoming....
$perma = false; if (isset($wp_query->query_vars['phpost_slug'])) #WHFIX 24/03/2015:
$perma = $wp_query->query_vars['phpost_slug'];
if($perma){
//we don't want to return a 404
$wp_query->set( 'is_404', false );
$phid = get_page_by_path($perma, OBJECT, 'post');
$postvote = get_post_meta($phid->ID, 'epicredvote' ,true);
$thumb = wp_get_attachment_image_src( get_post_thumbnail_id( $phid->ID ), 'single-post-thumbnail' );
$pluginfeat = get_post_meta($phid->ID,'phog',true);
$desc = get_post($phid->ID)->post_content;

UPDATE
I tried removing the anchor tags as well as the classes like this and it still isn't working:
<?php
if ( has_post_thumbnail()) {
the_post_thumbnail();
}
?>

The element you are changing is only the html wireframe for the onclick handlers to populate, the problem is, it didnt include a image on the original so you need to add that functionality. something like this should work (add to your footer)
var eventTargets=document.querySelectorAll('.hunt-row');
[].forEach.call(eventTargets, function(t){
t.addEventListener('click', function(){
console.log('clicked');
var img= this.querySelector('img').src;
//bind new src to modal thumb, this is not ideal as there is only a class rather than a id...
document.querySelector('.modal-thumb').src= img;
}, false);
});
Of course, im not sure how nice it will play with the other click handlers, you may need to remove the default and write your own to populate the model box onclick.
