Getting a specific post values to another div or modal

Question

So I was trying to loop all the post from wordpress with the_excerpt. Then I was stuck on how to get and pass the data from a single post by clicking a link or button to appear the_content() on a modal div.

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>

<div class="post">
    <h2><?php the_title(); ?></h2>

    <p><?php the_time('F jS, Y'); ?> by <?php the_author(); ?></p>
    <div class="blog-content">
        <?php the_excerpt(); ?>
    </div>
 </div> 
 <?php endwhile; else : ?>
 <p><?php esc_html_e( 'Sorry, no posts matched your criteria.' ); ?></p>

this is how my modal look like..

<div id="myModal" class="modal fade" role="dialog">
  <div class="modal-dialog">

    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal">&times;</button>
        <h4 class="modal-title">Modal Header</h4>
      </div>
      <div class="modal-body">

      <!-- the_content() in here-->

      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>

  </div>
</div>

not sure this will work

<button class="btn btn-primary tag_cnt" onclick="showModal('data')" type="button" value="<?php $post->post_content;?>"></button>

then use a function like this

function showModal(data)
{

   $("#myModal .modal-body").html(data)
   $("#myModal").modal();
}

but how do i transfer multiple values like the_content and the_title?

Answer 1

You can do it in different ways:

Json Encode

This is my favorite way of passing data/settings/etc to the front-end.

PHP

$obj=array(
    'content' => $post->post_content,
    'title' => esc_html( get_the_title() )
);

Now the button output will be like this:

HTML

<button class='btn btn-primary tag_cnt get_button_more_info' type='button' value='<?=json_encode($obj)?>'></button>

Javascript

(function($) {

  $('.get_button_more_info').on('click',function() {
    var obj = $(this).val();
    obj = JSON.parse(obj);

    $("#myModal .modal-body").html(obj.content)
    $("#myModal .modal-title").html(obj.title)
    $("#myModal").modal();
  });

})( jQuery );
