  • javascript popup that cancels the action if the user clicks "cancel": onclick="return confirm('Are you sure?'); Commented Aug 15, 2017 at 6:46

    Or here or in the next confirmation page you should make a POST instead of a GET request. To avoid browsers and search engines auto-deleting your content by accident. Commented Aug 15, 2017 at 6:47

    You should even be using a form with CSRF token instead of a simple link Commented Aug 15, 2017 at 6:59

Try this 

echo '<td><a href="candidates.php?id=' . $row['candidate_id'] . '" onclick="return confirm('Are you sure...?')">Delete Candidate</a></td>';

You really shouldn't be using a link in combination with javascript for a delete action.
@jeroen What are the downfalls to this? Personally, I've never used such combination before, as I would handle the confirmation before I make a POST request to manipulate the data.
See my comment below the question. And if javascript is disabled, there is no confirmation at all (Opera mini?).

Use confirm function from javascript

confirm('message');

echo '<td><a href="candidates.php?id=' . $row['candidate_id'] . '" onclick="return confirm('message goes here')">Delete Candidate</a></td>';
