wordpress - php question
 

hi, one of my blogs is running too slow because of the amount of posts (over 5000)
the index.php file of wp has the following code:

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

The have_posts() function is defined as follows:
############
./wp-includes/query.php: function have_posts() {
if ( $this->current_post + 1 < $this->post_count ) {
return true;
} elseif ( $this->current_post + 1 == $this->post_count && $this->post_count > 0 ) {
do_action_ref_array('loop_end', array(&$this));
// Do some cleaning up after the loop
$this->rewind_posts();
}

$this->in_the_loop = false;
return false;
}
#####################

Wordpress is returning EVERY single post (5000) in the database and then iterating over them performing a SQL query for each.
It does not help changing the theme because that routine is in wp itself not in the theme.

Anybody help ?

thanks

Your best bet is to limit the mysql_query, save beating the server. There are several ways to do this, check out http://www.phpsimplicity.com/tips.php?id=1 for some great howto's

There's gotta be a way to configure this without messing with the PHP code right?

I don't really know much about Wordpress or what the_post() is doing, but if worst comes to worst, you could always add a function to query.php that sets current_post to a few hundred less than the number of posts.


function jump_post($index)
{
$this->current_post=$index;
}

Try to re-code the loop with WP_Query() , but limiting the results posted.
THat should fix the slowness you describe...

I'm 99% certain it's only looping over the number of posts defined to show on the home page.

From the codex:

$post_count
The number of posts being displayed.

Not the total number of posts in your DB.
