Is it normal to have multiple postmeta tables in a WordPress database? No, each site has a single post/user/term and comment meta table. A multisite will have a set of those tables for each site in the multisite, plus network/site meta tables. What could be the reason behind this duplication? WP wouldn’t duplicate the tables … Read more
It appears, at least in cPanel, the lines in question were not required in the export, with the unsurprising consequence of the other encapsulated sql statements defaulting to reference the current database only. Turns out to be convenient when more than one database is configured, so long as there are no statements that select objects … Read more
Using the FPDF library (found at http://www.fpdf.org) you generate PDFs on the fly using any data from your WP site. function wpse60844_generate_pdf( $post ) { /* Define paths for where the PDF will be permanently or temporarily saved */ define( ‘FPDF_PATH’, plugin_dir_path( __DIR__ ) . ‘/fpdf/’ ); define( ‘SAVE_PATH’, plugin_dir_path( __DIR__ ) . ‘fpdf/pdfs/’ ); … Read more

Here’s the adjusted code: $pid = 55276; $post = get_post($pid); echo ‘original post:<BR>’.$post->post_excerpt.'<HR>’; $newtext=”some textt2″; global … Read more
This definitely is possible. You won’t be able to get your media back with just the sql file but you can get your content. Assuming this is your content and you have a proper admin account this is fairly easy. Install a fresh version of WordPress (on a web-server or locally). In phpMyAdmin. Delete the … Read more
The errors were generated because there was a plugin that forced sql modes to be used on the database that are actually “incompatible” with wordpress. The following code was sadly executed for every request… private function set_sql_mode() : void { // Make sure no sql modes can be blocked (By wordpress built-in incompatible modes) add_filter(‘incompatible_sql_modes’, … Read more

I’ve created an alternative wp-config.php and renamed to wp-config2.php with the same configuration except for the table prefix. Then I tried by editing all the plugin files. At the top of each file I found: if ( ! defined( ‘ABSPATH’ ) ) { exit; // Exit if accessed directly! } And I replaced it for: … Read more
