add_shortcode("showfiles", "dump_files");
// end shortcode

This shortcode should go in your functions.php theme file. It is designed to pull in all post attachments, if any exist, and then print them out on the page in an unordered list. You can additionally specify mime types as a parameter in the get_children() function.

Use it in your theme by typing [showfiles] in your content.

Here’s the function

function set_post_background() {
	global $post;
	$bgimage = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), "Full");
	if (!empty($bgimage)) {
		return '<style type="text/css">body {background-image: url('.$bgimage[0].');}</style>';
	}
}

Here’s what it does:

1. The featured image source is pulled from the post data
2. If the featured image URL exists, the function prints a style tag that sets the body’s background-image to that url. If not, it doesn’t do anything.

Call this function anywhere in your theme like so:

<?php echo set_post_background(); ?>

And that’s it.

It is possible to add a filter function to add new text to the password protected page. The code to add to your functions.php files is as follows:

<?php
add_filter( 'the_password_form', 'custom_password_form' );
function custom_password_form() {
	global $post;
	$label = 'pwbox-'.( empty( $post->ID ) ? rand() : $post->ID );
	$o = '<form action="' . get_option('siteurl') . '/wp-pass.php" method="post">
	' . __( "This post is password protected and this is what I want to say about that. To view it please enter your password below:" ) . '
	<label for="' . $label . '">' . __( "Password:" ) . ' </label><input name="post_password" id="' . $label . '" type="password" size="20" /><input type="submit" name="Submit" value="' . esc_attr__( "Submit" ) . '" />
	</form>
	';
	return $o;
}
?>

But with just a tiny bit more coding…

…and an if statement, you can add a check to see if a custom field exists, and if it does, to spit it out instead of using the default text. Added code is in Yellow.

add_filter( 'the_password_form', 'custom_password_form' );
function custom_password_form() {
	global $post;
	$label = 'pwbox-'.( empty( $post->ID ) ? rand() : $post->ID );
	$o = '<form class="protected-post-form" action="' . get_option('siteurl') . '/wp-pass.php" method="post">';
 if (get_post_meta($post->ID, 'password-prompt-text', true)) {
 $o .= get_post_meta($post->ID, 'password-prompt-text', true);
 } else {
 $o .='<p>'. __( "This post is password protected. To view it please enter your password below:" ).'</p>';
 }
	$o .= '<label for="' . $label . '">' . __( "Password:" ) . ' </label><input name="post_password" id="' . $label . '" type="password" size="20" /><input type="submit" name="Submit" value="' . esc_attr__( "Submit" ) . '" />
	</form>';
	return $o;
}

The variable $o begins return a string. My if statement in yellow, interrupts the string with an if statement to see if the post has a custom field called password-prompt-text, and if it does, uses it instead of the text “This post is password protected…”.

Using this method, you can provide HTML into the description, so go crazy. I used H2 for title, then a paragraph for description. The cool thing about this, is that because of the else: it degrades nicely if you don’t have the custom field added to the post.

Hope that helps somebody.

So if you start the WordPress upgrade and it gets locked up and leaves you hangin’, here’s what you do:

Note: You should always backup your database and wp-content directory before beginning a WordPress update, even an automatic one. Also, you should ALWAYS rename a default theme like TwentyTen to a different name or it might get overwritten in an automatic update.

1) Download the latest version of WordPress from WordPress.org

2) With an FTP program (FileZilla for Mac/PC, Cyberduck for Mac; I prefer Transmit, bit it ain’t free). Upload the entire WordPress install, except for the wp-content folder. This should overwrite all files in the WordPress Core. Unless you’ve messed with the core (which you shouldn’t have), this will not affect your files.

3) Remove the file called “.maintenance” from your site’s root directory (this is what is triggering the maintenance message).

4) Navigate to the appropriate wp-admin folder. WordPress will ask you to upgrade the database. Click the button and your back to where you were before, only now your upgraded.

I hope someone finds this helpful.

In any single.php template, use this code:

Using $post->ID

<?php

$pages = get_posts('numberposts=-1&orderby=menu_order&order=ASC&post_type=page&post_status=publish&post_parent='.$post->ID);

if (!empty($pages)) {

$has_children = true; // Page has children

} ?>

Using get_the_ID()

<?php

$the_ID = get_the_ID();

$pages = get_posts('numberposts=-1&orderby=menu_order&order=ASC&post_type=page&post_status=publish&post_parent='.$the_ID);
if (!empty($pages)) {
$has_children = true; // Page has children

} ?>

Now you’re even set to loop through your pages to create your sub-menu.

Hope someone finds that helpful

• WordPress Template Tag: get_posts()

I’ve been trying to come up with a solution for this. So I asked my friend Brian Morykon his thoughts. He suggested using spans instead of iframes, then when the dom was ready to replace the spans with iframes throughout, that way it would load after everything else. I tried it, and it worked. The only thing that is a little different here is that I am only using the src attribute from the spans, the other parameters I’m filling in on .replaceWith()

Facebook Like button (using span instead of iframe)

<div class="facebooklike">
 <span class="facelike" src="http://www.facebook.com/plugins/like.php?href=<?php the_permalink(); ?>&amp;layout=button_count&amp;show_faces=false&amp;width=60px&amp;action=like&amp;colorscheme=light&amp;height=21"></span>
</div>

jQuery function to find and replace spans with class ‘facelike’:

jQuery("span.facelike").each(function() {
 var url = jQuery(this).attr("src");
 jQuery(this).replaceWith('<iframe src=' + url + ' scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:60pxpx; height:21px;" allowTransparency="true" />');
 });

Note:

1. The jQuery is replacing the span with class ‘facelike’ with an iframe, with the attribute the same as the span. the other parameters (frameborder, style, scrolling) get passed from the jquery and not pulled out of each span (it’s much easier this way, plus you can change them all at once if you need to adjust).
2. This doesn’t have anything to do with jQuery, more with WordPress, but I’m using the_permalink() to pass the url to like, so you have to run this inside the loop.

WordPress Snippets (http://wp-snippets.com) is a really neat resource that has lots of little known WordPress snippets. They’re adding more every day, it’s very exciting for a geek like me, so I thought it would be exciting for other geeks too.

Almost all of the code snippets are best used in your functions.php file. Go, have fun.

Quick Post enables a WordPress user to quickly add multiple posts or pages at once. Version 1.3 has the following features:

• Specify whether content to be added is a post or a page
• If Pages are added, user can specify Parent Pages (to add children)
• User can choose a page template from a drop down
• User can specify the Author of new pages
• User can specify post status (Published / Draft / Pending Review)
• User can add as many posts/pages as they choose by clicking “add more”
• User can choose a category from a drop down
• User can add tags to individual posts

So, if this plug-in sound like it might help you, download it.

A little more detail:

This plugin uses the WordPress function wp_insert_posts() to add multiple posts at once. I wrote a blog post awhile ago on this same topic, using a PHP file that you would manually execute by navigating to it in your browser, but this way is much easier / faster / more flexible.

Use this plugin if you are:

• Quickly inserting multiple posts whose content you already have written
• Framing out a new site with desired pages and sub-pages
• Inserting multiple posts to be edited later (with Post Status option)

Plugin now in WordPress plugin repository.

I’ve updated the links here to go to the WordPress plugin repository, which is where I will be updating it. You can add this plugin in your WordPress backend, although for the first few days “Quick Posts” won’t bring up the plugin, so you can search my handle: jhinson as an author.
