image URL changed in wordpress

Question

Using WordPress plugin –

Search And Replace

This is simple WordPress plugin, Does database query to replace any content. This plugin can be used to replace a string ( say – localhost:8888 ) with a new one ( domain.com ) .

Direct updating MySQL Database –

Or, If you’ve access to MySQL Server you can simply replace the old domain with new one using this SQL Query
UPDATE wp_posts 
SET post_content = REPLACE
(
    post_content,
   'http://universitycompare.com:8888/imagepathurl/etc',
   'http://universitycompare.com/imagepathurl/etc'
);
^{( Note – Above code is not tested, Backup your database before using it )}

Using WordPress Filter –

Here’s simple filter to used in functions.php, Simply replaces the old domain name with new one
add_filter( 'the_content', 'wpse64204_img' );
function wpse64204_img( $content ) {

    $old_url="/universitycompare.com:8888/";
    $new_url="universitycompare.com";

    $new_content = preg_replace($old_url, $new_url, $content);
    return $new_content;
}
^{( Note – This does not updated the Database )}
