<p>OK, I got it using the following code:</p> <p>In main PHP plugin file:</p> <pre><code>echo "<script src='URL PATH TO/ajax_file.js' type='text/javascript'></script>"; add_action( 'wp_ajax_foobar', 'foobar_handler' ); add_action( 'wp_ajax_nopriv_foobar', 'foobar_handler' ); function foobar_handler() { // Handle request then generate response echo "ANYTHING..."; // do stuff here die(); // avoids extra 0 at the end of the response } </code></pre> <p>In ajax_file.js: (referred to above in script tag)</p> <pre><code>jQuery(document).ready(function($) { $('#id_to_submit_button').click( function() { var data = { action : 'foobar', Whatever : '1234', } ; // ajaxurl only needed for front - facing public pages, comment out for back end pages var ajaxurl = 'http://SITE_URL/wp-admin/admin-ajax.php'; jQuery.post(ajaxurl, data, function(response) { alert('Got this from the server: ' + response); } ); } ); } ); </code></pre> <p>As soon as I included the script in this way it worked, it would not when placed in a PHP function as many sources suggest. I tried soooo many other ways that should have worked. I went step by step on the Wordpress codex pages (many times) and several other tutorials. Enqueueing scripts, registering scripts, following all recommended practices. I still don't understand why this way works for me and all the other "correct" ways didn't. Could be something in my local server environment. Big thanks to those who answered and tried to help. God knows I have gotten the quick answer on StackOverflow enough times, I hope this saves someone the long hours I spent testing and troubleshooting...</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
