In wordpress <?php bloginfo('url'); ?>
<?php bloginfo('url'); ?>
is the main page's url, then, how to write a require_once include <?php bloginfo('url'); ?>
<?php bloginfo('url'); ?>
Something I write like this is not worked :{
<?php require_once ( "".bloginfo('url')."/database.php"); ?>
The bloginfo function will echo the data, not return it. As such, you need to use the get_bloginfo function, as this simply returns the data.
For example:
<?php require_once (get_bloginfo('url') . '/database.php'); ?>
However, it should be noted that if you're trying to include a local file you should simply use the ABSPATH
define, as this will return the base install directory, which is what I'm guessing you're attempting to do.
ie: If "database.php" is located in the root WordPress directory, then...
<?php require_once (ABSPATH . '/database.php'); ?>
... should work.
Our you could consider using home_url(); home_url
If you are just trying to access wordpress database if so use the global $wpdb variable
