First of all, never use query_posts. Rather use WP_Query to construct your custom query which is the prefered way You are also using the category_name parameter wrong. If you look at the WP_Query documentation, it states category_name (string) – use category slug (NOT name). Go and have a look at the examples given in the … Read more
its a syntax error according to error message. starements like below might work for you. global $wpdb; $wpdb->show_errors(); $tableCustom = ‘join_users_defis’; $sql = “SELECT * FROM {$wpdb->postmeta}”; $requeteAffichage = $wpdb->get_row( $sql ); //or $requeteAffichage = $wpdb->get_results( $sql ); var_dump($requeteAffichage);
You can do this with the woocommerce_add_error filter. Add the following to your functions.php file. // alter the subscriptions error function my_woocommerce_add_error( $error ) { if( ‘The generic error message’ == $error ) { $error=”The shiny brand new error message”; } return $error; } add_filter( ‘woocommerce_add_error’, ‘my_woocommerce_add_error’ );
This is a PHP variable scope issue, there is no $wpdb defined in your function. Add global $wpdb; before trying to use the $wpdb object.
Ran into the same issue. @Patriek is correct. The ‘taxonomies’ argument must be an array, hence the plural. E.g. $args = array( ‘taxonomies’ => array( ‘myTaxonomy’ ) ); This corrects the error.

I had a similar problem: calling error_log() from wp-config.php works, but calling it from functions.php does not work for me. I couldn’t solve this issue but I’ve found a workaround that allowed me to do some sort of debugging at least. I gave up on error_log() and just wrote an own function that logs into … Read more
How should I handle errors within a plugin?
Not WordPress related, so I am not sure if I have the right to reply in here, but still increase max_user_connections in my.cnf MySQL configuration file since you are just testing. There are number of causes for running out of connections, the most common ones involving when the Web/App server is creating unexpectedly large numbers … Read more
You might be able to narrow it down using output buffering on different hooks… eg. add_action(‘plugins_loaded’,’start_buffer’); function start_buffer() {ob_start();} add_action(‘wp_loaded’,’end_buffer’); function end_buffer(); {ob_end_clean();} ie. this is a broad test but if the error goes away, the output is happening between those two actions, if not try hooking in earlier (unlikely but could be later too) … Read more
