WP_Query中的重复函数

Question

I have a WP_Query that shows a list of posts. Pretty standard, however, within that I'm call multiple instances of functions like the_title(); for use in a popup modal that is supposed to display the post that was clicked on, but instead just shows the first one in the loop again.

<?php
   $members = new WP_Query( 'post_type=member' );
   if ( $members->have_posts() ) :
   while ( $members->have_posts() ) : $members->the_post();

   // get the src of the post thumbnail
   $src = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'full', false, '' ); 
   $thumbnailSrc = $src[0];  
   ?>

        <div class="col-sm-3 member">
          <img src="<?php bloginfo('template_directory'); ?>/timthumb.php?src=<?php echo $thumbnailSrc; ?>&h=250&w=250&zc=1q=100" alt="" data-toggle="modal" data-target="#memberModal">
          <h4><?php the_title(); ?></h4>
          <p><?php the_field('member_title'); ?></p>
        </div>
        <div class="modal fade" id="memberModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
          <div class="modal-dialog">
            <div class="modal-content">
              <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
              </div>
              <div class="modal-body">
                <img src="<?php bloginfo('template_directory'); ?>/timthumb.php?src=<?php echo $thumbnailSrc; ?>&h=300&w=650&zc=1q=100" alt="" class="img-responsive">
                <h2><?php the_title(); ?></h2>
                <p><?php the_field('member_title'); ?></p>
                <p class="lead"><?php the_field('member_introduction'); ?></p>
                <?php the_field('member_description'); ?>
              </div>
            </div><!-- /.modal-content -->
          </div><!-- /.modal-dialog -->
        </div><!-- /.modal -->

        <?php endwhile; else:
          echo '<p>Sorry, there are no posts to display</p>';
          endif;
        ?>

In the example above, a div.member is created for each post. But then the div.modal only shows the first post.

In a way, I'm trying to create one of these (div.member + div.modal) for each post.

UPDATE:

Here is a visual representation. The loop spits out the four 'members' in the post_type with the data for each one.

But no matter which one I click on, the modal just fetches the data from the first post.

Your loop is creating multiple modals all with the same classes and IDs. When you click on the link to display the modal, the JS will only get the first item in the DOM. I suggest you create a loop counter to increment your IDs.

Before the while loop starts ->

<?php $count = 0; ?>

Just inside the while loop ->

<?php $count++; ?>

Then for your ID ->

<div class="modal fade" id="memberModal<?php echo $count; ?>" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">

This would increment the IDs which you can then target with jQuery. If you want this to function correctly, you're going to have to count the number of entries and then loop in jQuery as well or you could localize the script and output the variables to your JS.
