change wordpress url in database

Manuel Bogner — Fri, 17 Apr 2020 15:28:37 +0000

if you need to move wordpress to a new url then the following sql script will be handy (update the urls in it of course):

UPDATE wp_options SET option_value = replace(option_value, 'http://www.oldurl', 'http://www.newurl') WHERE option_name = 'home' OR option_name = 'siteurl';

UPDATE wp_posts SET guid = replace(guid, 'http://www.oldurl','http://www.newurl');

UPDATE wp_posts SET post_content = replace(post_content, 'http://www.oldurl', 'http://www.newurl');

UPDATE wp_postmeta SET meta_value = replace(meta_value,'http://www.oldurl','http://www.newurl');

WordPress force SSL admin area

To force wordpress to use SSL for the admin area you simply can add a line to your wp-config.php file located in the root of your wordpress installation:

define('FORCE_SSL_ADMIN', true);

WordPress 3.9.1 with PostgreSQL

Manuel Bogner — Sun, 20 Jul 2014 08:53:12 +0000

Till 3.8 everything was ok and my blog survived every update. But for 3.9 this changed as the postgresql driver I am using (PG4WP)is not compatible out of the box anymore. There were no updates for the last two years. Here are the two fixes I had to make:

To resolve the error “Call to undefined function wpsql_errno()” I added the following code at the end of the file wp-content/pg4wp/driver_pgsql.php:

function wpsql_errno($connection) {
    $result = pg_get_result($connection);
    $result_status = pg_result_status($result);
    return pg_result_error_field($result_status, PGSQL_DIAG_SQLSTATE);
}

The second error to resolve was “Missing argument 3 for wpsql_result()”. To fix this I replaced the function wpsql_result in the file “wp-content/pg4wp/driver_pgsql.php” on line 58-59:

function wpsql_result($result, $i, $fieldname = null) {
    if (is_resource($result)) {
        if ($fieldname) {
            return pg_fetch_result($result, $i, $fieldname);
        } else {
            return pg_fetch_result($result, $i);
        }
    }
}

After these two changes my blog is running again with new wordpress version =)

See http://blog.coffeebeans.at/?p=813 for a fixed version.

WordPress problem with PostgreSQL

Manuel Bogner — Thu, 02 May 2013 19:03:27 +0000

I found strange errors like the following in my apache_error.log

[Thu May 02 20:59:58 2013] [error] [client 84.114.158.229] WordPress database error ERROR:
  column p.id does not exist\\\\\\\\nLINE 1: SELECT p.id FROM wp_posts AS p  WHERE ...

I found out that this comes from line 1178 in wp-includes/link-template.php. Just change the p.id at after the SELECT to p.ID and save the file (SELECT p.ID …). That’s the trick.
