WordPress Custom Fields Primer Tutorial<\/p><\/div>\n

\nI spy with my little eye something beginning with … 💡<\/span>
\nYes, 💡<\/span>
\nUp above, 💡<\/span>\n<\/p><\/blockquote>\n


\nAw ... what a bright idea?! How come I click on the light bulb (💡<\/span>) and it has dropdown options unique to this blog post?
\n<\/code><\/p>\n

\nGlad you asked. And all because …<\/a>\n<\/p><\/blockquote>\n

Let’s talk about WordPress blog Custom Fields<\/a>, and an associated great link we stumbled upon<\/a>. We followed its advice to change Theme code … yay!!!! Except this time, it wasn’t (good ol’) header.php that changed for our Custom Field foray (we’ve codenamed “Operation 4A”<\/font> … tee hee<\/font>).<\/p>\n

Working to a plan like this, often the first question is (especially with event-driven programming code) “Where is the intervention point?”.<\/p>\n

\nYou will need to enter your custom fields code inside the WordPress loop.
\nLook for the line that looks like this:
\n
\n<?php while ( have_posts() ) : the_post(); ?>
\nYou want to make sure that you add your code before the following line:
\n
\n<?php endwhile; \/\/ end of the loop. ?>\n<\/p><\/blockquote>\n

… good advice, and looking in the themes “twentyten” folder several PHP files had these two. But trial and error (just placing <?php echo ‘yoo hoo!’; ?>) we found that “single.php” could be tweaked to change the WordPress blog webpage here, and intervene. Place the intervention near “endwhile” and it goes down the bottom of the post’s content, and near “while ( have_posts() ) : the_post();” you get it up near the top of the post’s content (the placement we opted for).<\/p>\n

Working to a plan like this, often the next question is “What do you want to do now that you know where to intervene?” and here we decided we wanted a dropdown way to navigate to links that are related to the content in one of 5 ways …<\/p>\n
