Short answer: it’s not possible. Long answer: you should try $wpdb->query instead and write a regular SQL query, something like this: UPDATE table_name SET notes = CONCAT(notes, ‘text to append’) WHERE note_id = ‘313’ Please note it’s only an example and you should use $wpdb->prepare to also sanitize variables properly.
This isn’t a WordPress question this is a PHP question. Your foreach loops through all the $checkboxes putting one in the $check variable each time, so your insert() call only inserts the last value for $check, because it’s not inside that foreach loop. You probably want: global $wpdb; foreach( $checkboxes as $check ) { $wpdb->insert(‘data’,array(‘fruit’ … Read more
Found a couple of things and am including what I believe will work to correct your issue. (As an aside, you should try and simplify your initial attempts so you can isolate what works and what doesn’t. This is really complex for an initial attempt.) One thing, you’ll struggle to have a field named timestamp, … Read more
Your SQL command is highly insecure and open to security issues like SQL injection, so even if this may not answer the question, I strongly suggest you to use $wpdb->prepare() and $wpdb->esc_like() — the latter is used to escape the % character in SQL. Additionally, you can simply use $wpdb->posts to output the table name … Read more
I am so silly. With this in the end, I set a PHP variable that I needed instead of the “@SET”. My final code was this: $group_sql = “SELECT product_group FROM insert_temporary LIMIT 1”; $group = $wpdb->get_var($group_sql); $sql = “SELECT * FROM insert_temporary WHERE product_group in (SELECT product_group FROM insert_temporary WHERE product_group = ‘”. $group … Read more
The error in question happened because you did not properly build your SQL query/statement: The column name in your query is hashcode, and you are trying to get the row where the column value matches the value of the $file_hash variable, i.e. WHERE {$file_hash} = `hashcode`. But because the value is a string/text (and not … Read more
There are two issues I see in your code: The $searchIP is actually outside of the $wpdb->prepare(): (I didn’t use the full query so that you’d see the issue clearer) $StatusCheck = $wpdb->get_var( $wpdb->prepare(“SELECT payment_status …”),$searchIP); So you should correct that, like so: (reindented for clarity) $StatusCheck = $wpdb->get_var( $wpdb->prepare( ” SELECT payment_status FROM {$ipn_tables} … Read more
One approach (avoiding PHP timeouts) for a local Linux Cron Job (for exact timing) is creating a WP-CLI command (does not run in the browser), like: <?php /* Plugin Name: WP-CLI Foo */ function foo_command( $args ) { // Adjust to your needs … WP_CLI::success( $args[0] ); } WP_CLI::add_command( ‘foo’, ‘foo_command’ ); and the corresponding … Read more
Well, you don’t need the second $wpdb->prepare() and just do $wpdb->query( $query );. The reason is because the $query does not contain any placeholders just as stated in the notice; only the items in $values contain the placeholders, but you already prepared them in the foreach. Additionally, be sure to run the query() only if … Read more
That’s not what the $tables variable does, and there is no such thing as a registered custom table. These variables are an internal API not intended for plugin/theme developer use. The $wpdb->mytable pattern itself is just something someone did because they wanted to avoid prefixing manually that caught on in early WordPress articles. The reason … Read more
