How to change posts_per_page to 5 instead of 10.
default posts_per_page is 10 in backend -options-reading, but I dont want to change option reading blog by blog.

Edit themes/index.php


<?php $custom_loopcount = 0; ?>
<?php if (have_posts()) : while ((have_posts()) && ($custom_loopcount < 5)) : the_post(); ?>
<?php if (is_home()) $custom_loopcount++; ?>


how come themes' "Previous Entries" is show up same posts with first index page?

after code added, how come themes' "Previous Entries" never show up at the bottom?

dig... look for solution.

Well we can change a setting in your defaults to the new number.

Open up wp-admin/upgrade-schema.php and change:

add_option('posts_per_page', 10);

to:

add_option('posts_per_page', 5);

You can try running the Dashboard -> System Admin -> Upgrade and see if that changes it. You may luck out. :)

is this saying that 10 posts per page is hard coded?

thanks,

ladynada, it is hard coded as the default for new blogs.
You can run a script to change it for all current users. I do it when needed.

For anyone interested, I have released the script I use to change option for all existing blogs. See it here:

Yes, that thread is a little old, but it works nonetheless.

lunabyte, that might do the job. My script is some what more general. Maybe I should post it in a different thread
