use initial caps

add this to your function.php

function initial_cap($content){
// Regular Expression, matches a single letter
// * even if it's inside a link tag.
$searchfor = '/>(< a >]+>)?([^<s])/';
// The string we're replacing the letter for
$replacewith = '>$1<span class="capital">$2</span>';
// Replace it, but just once (for the very first letter of the post)
$content = preg_replace($searchfor, $replacewith, $content, 1);
// Return the result return $content; }
// Add this function to the WordPress hook
add_filter('the_content', 'initial_cap');

add the styling to your css

span.initialcap{ float: left; font-size: 40px; line-height: 35px; /* Double the line height minus 1 pixel */ font-family: Georgia, "Times New Roman", Times, serif; color: #2583ad; /* Blue */ padding-right: 5px; }

display a random ‘Read More’ link

Copy and paste this code somewhere in the index.php or functions.php file of your theme (but make sure you paste it before the loop):

<?php $more_strings = array("Read More...", "Keep on Reading...", "Wait! There's more...", "Read the rest of the article..."); ?>

You can add as many strings as you want.

Then change the the_content(); bit to this:

the_content($more_strings[rand(0,count($more_strings))]);

List WordPress Users

< ul id="membersList" >
<?php
/* First we set how we'll want to sort the user list.
* ID - User ID number.
* user_login - User Login name.
* user_nicename - User Nice name ( nice version of login name ).
* user_email - User Email Address.
* user_url - User Website URL.
* user_registered - User Registration date.
*/
$szSort = "user_nicename";
/*
Now we build the custom query to get the ID of the users.
*/
$aUsersID = $wpdb->get_col( $wpdb->prepare( "SELECT $wpdb->users.ID FROM $wpdb->users ORDER BY %s ASC" , $szSort ));
/*
Once we have the IDs we loop through them with a Foreach statement.
*/
foreach ( $aUsersID as $iUserID ) :
/*
We use get_userdata() function with each ID. */ $user = get_userdata( $iUserID );
/*
Here we finally print the details wanted. Check the description of the database tables linked above to see all the fields you can retrieve. To echo a property simply call it with $user->name_of_the_column. In this example I print the first and last name.
*/
echo '< li >' . ucwords( strtolower( $user->first_name . ' ' . $user->last_name ) ) . '< /li >';
/*
The strtolower and ucwords part is to be sure the full names will all be capitalized. */
endforeach; // end the users loop. ?> < /ul >

Get Images Attached to a Post

use this in your function.php file

function bdw_get_images() {
// Get the post ID
$iPostID = $post->ID;
// Get images for this post
$arrImages =& get_children('post_type=attachment&post_mime_type=image&post_parent=' . $iPostID );
// If images exist for this page
if($arrImages) {
// Get array keys representing attached image numbers
$arrKeys = array_keys($arrImages);
// Put all image objects into new array with standard numeric keys (new array only needed while we sort the keys)
foreach($arrImages as $oImage) { $arrNewImages[] = $oImage; }
// Bubble sort image object array by menu_order TODO: Turn this into std "sort-by" function in functions.php
for($i = 0; $i < sizeof($arrNewImages) - 1; $i++) { for($j = 0; $j < sizeof($arrNewImages) - 1; $j++) { if((int)$arrNewImages[$j]->menu_order > (int)$arrNewImages[$j + 1]->menu_order) { $oTemp = $arrNewImages[$j]; $arrNewImages[$j] = $arrNewImages[$j + 1]; $arrNewImages[$j + 1] = $oTemp; } } }
// Reset arrKeys array
$arrKeys = array();
// Replace arrKeys with newly sorted object ids
foreach($arrNewImages as $oNewImage) { $arrKeys[] = $oNewImage->ID; }
// Get the first image attachment
$iNum = $arrKeys[0];
// Get the thumbnail url for the attachment
$sThumbUrl = wp_get_attachment_thumb_url($iNum);
// UNCOMMENT THIS IF YOU WANT THE FULL SIZE IMAGE INSTEAD OF THE THUMBNAIL //
$sImageUrl = wp_get_attachment_url($iNum);
// Build the string
$sImgString = '< a href= "' . get_permalink() . '">' . '' . '< /a >'; // Print the image
echo $sImgString; } }

Thumbnailed Recent Posts

create a thumbnail for each of your last 5 posts (and every subsequent post going forward). Upload it and then paste it's location into a new custom field with a key called thumb.

create a new Loop somewhere in one of your template files that pulls this thumbnail in and displays it in an unordered list

< ul class="thumb_recent" >
<?php query_posts('showposts=5'); ?>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<?php $thumbnail = get_post_meta($post->ID, 'thumb', true); ?>
< li > < a href ="<?php the_permalink(); ?>" title="<?php the_title(); ?>">
" alt="<?php the_title(); ?>" /> <span>
<?php the_title(); ?></span>< /a > < /li >
<?php endwhile; endif; ?>
< /ul >;

style it via css:

ul.thumb_recent {
list-style:none;
margin:30px 0 0 0;
padding:0;
}

ul.thumb_recent li {
float:left;
margin:0 5px 0 0;
position:relative;
}

ul.thumb_recent li img {border:3px solid #7BA2C7;}
ul.thumb_recent li a:hover img {border:3px solid #666;}
ul.thumb_recent li span {
text-decoration:none;
display:none;
text-align:left;
position:absolute;
top:-15px;
left:0px;
width:400px;
color:#666;
text-transform:uppercase;
font-family:arial;
font-size:11px;
}

ul.thumb_recent li a:hover span {display:block;}

Post Specific CSS Overrides

create a custom field called my-css. For its value, paste your new CSS: simple example:
body { background:#000 !important; }

insert that custom field CSS into the header.php file. In that template file, find the line that declares your CSS stylesheet, and paste this code below it.

<?php if (is_single()) { ?>
<?php while (have_posts()) : the_post(); ?>
<?php $newcss = get_post_meta($post->ID, 'my-css', true); ?>
<style type="text/css">
<?php echo $newcss; ?>
</style>
<?php endwhile; ?>
<?php rewind_posts(); ?>
<?php } ?>

Reverse post order

check your index.php file, look for this bit of code:

<?php if(have_posts()) : ?><?php while(have_posts()) : the_post(); ?>

Right before that line, add this code:

<?php query_posts($query_string . “&order=ASC”) ?>

By default, WordPress category permalinks are displayed that way:

http://yoursite.com/category/yourcatname

how to remove it, backup your current .htaccess file. Then, open it and append the following line:

RewriteRule ^category/(.+)$ http://www.yoursite.com/$1 [R=301,L]
Once saved, your categories pages will be displayed like this:

http://yoursite.com/yourcatname

ATTENTION: won't work on hosts like bluehost or similar due to their
installment
