When you run wordpress under xamm,

2. Search”memory” and get the following:

;;;;;;;;;;;;;;;;;;;

;;;;;;;;;;;;;;;;;;;

max_execution_time = 60     ; Maximum execution time of each script, in seconds
max_input_time = 60    ; Maximum amount of time each script may spend parsing request data
memory_limit = 32M      ; Maximum amount of memory a script may consume (16MB)

3. Modify the value of “memory_limit =” ，usuall change it to 64M.

It is very simple:

<?php if ($wp_query->current_post == 0) : ?>

<div style=”float:right”>

ads come here.

</div>
<?php endif; ?>

If you don’t want the ads show at homepage, using:

<?php if (!is_home()) ?>

It is very easy to tag cloud show the same size font and in list style, there are 2 ways to do this:

 1. Change sidebar.php in templates:

<li>

<h2>Tag Cloud</h2>

<?php wp_tag_cloud(‘smallest=8&largest=8&number=45&orderby=name&format=list’); ?>  <!– wp_tag_cloud(‘smallest=8&largest=8&number=45&orderby=name&format=list’)–>
</li>

another way is change code in widgets.php inside include document:

function wp_widget_tag_cloud($args) {
 extract($args);
 $options = get_option(‘widget_tag_cloud’);
 $title = empty($options['title']) ? __(‘Tags’) : apply_filters(‘widget_title’, $options['title']);

 echo $before_widget;
 echo $before_title . $title . $after_title;
 wp_tag_cloud(”); //wp_tag_cloud(‘smallest=8&largest=8&number=45&orderby=name&format=list’);
 echo $after_widget;
}

If you want your posts show from lowest to highest, it is very simple, just add:
<!–p query_posts($query_string.’&order=ASC’);–>

for example, the following code will let all your post show from lowest to highest:

<!–p query_posts($query_string.’&order=ASC’);–>
<!–p if (have_posts()) : while (have_posts()) : the_post();–>

If you want to list 50 posts, use the following code:

<ul>
 <?php
 global $post;
 $myposts = get_posts(‘numberposts=-1′);
 foreach($myposts as $post) :
 ?>
    <li><a href=”<?php the_permalink(); ?>”><?php the_title(); ?></a></li>
 <?php endforeach; ?>
 </ul>

if you want to list all the posts, use the following codes:

<ul>
 <?php
 global $post;
 $myposts = get_posts(‘numberposts=5′);
 foreach($myposts as $post) :
 ?>
    <li><a href=”<?php the_permalink(); ?>”><?php the_title(); ?></a></li>
 <?php endforeach; ?>
 </ul>

Display a list of 15 posts selected randomly by using the MySQL RAND() function for the orderby parameter value:

 <ul><li><h2>A random selection of kingphp posts</h2>
    <ul>
 <?php
 $rand_posts = get_posts(‘numberposts=15&orderby=rand’);
 foreach( $rand_posts as $post ) :
 ?>
    <li><a href=”<?php the_permalink(); ?>”><?php the_title(); ?></a></li>
 <?php endforeach; ?>
    </ul>
 </li></ul>

Retrieve a Particular Post
<?php
// retrieve one post with an ID of 5
query_posts(‘p=5′);     
?>
If you want to use the Read More functionality with this query, you will need to set the global $more variable to 0.

<?php
// retrieve one post with an ID of 5
query_posts(‘p=5′);
     
global $more;
// set $more to 0 in order to only get the first part of the post
$more = 0;

// the Loop
while (have_posts()) : the_post();
  // the content of the post
  the_content(‘Read the full post »’);
endwhile;
?>
Retrieve a Particular Page
To retrieve a particular page, you could use the following:

<?php
query_posts(‘page_id=7′);      //retrieves page 7 only
?>

or

<?php
query_posts(‘pagename=about’); //retrieves the about page only
?>

get_posts() can be used to collect and display any number of random posts you want. Here’s an example that lists the titles (as links) of four random posts:

<ul><li><h2>Some Random Posts</h2>
<ul>
<?php
$rand_posts = get_posts(‘numberposts=4&orderby=RAND()’);
foreach( $rand_posts as $post ) :
?>
<li><a href=”<?php the_permalink(); ?>”><?php the_title(); ?></a></li>
<?php endforeach; ?>
</ul>
</li></ul>

<?php $posts = get_posts( “category=1&numberposts=10″ ); ?>
<?php if( $posts ) : ?>
<ul><?php foreach( $posts as $post ) : setup_postdata( $post ); ?>
<li>
<a href=”<?php the_permalink() ?>” rel=”bookmark” title=”<?php the_title(); ?>”><?php the_title(); ?></a>
</li>
<?php endforeach; ?>
</ul>
<?php endif; ?> 

 category=1&numberposts=10, means category 1, and list 10 posts

add the code at your wordpress homepage, you blog will looks more great.

if you change numberposts=10 to -1, it will show all posts under the category.
