log_query_custom_data filterIt’s like when you’re cooking and want to add your secret spice mix to a dish. The
log_query_custom_data filter in WordPress lets you tweak the query data just the way you want. But remember, it’s best to add your own flavor in a new spot so you don’t mess up the original taste. You can add this filter to your theme’s functions.php or create a custom plugin. At
WePlugins, we always recommend the plugin route to avoid any hiccups during theme updates.
Before diving in, here’s a quick rundown of the parameters you’ll be working with:
- $query_data: Custom query data in an array.
- $query: The SQL query as a string.
- $query_time: Time spent on the query in seconds (float).
- $query_callstack: Comma-separated list of calling functions (string).
- $query_start: Start time of the query as a Unix timestamp (float).
Example 1: Basic Hook Registration
Here’s how you can register the log_query_custom_data filter with a simple callback function.
function weplugins_modify_log_query_custom_data_defaults($query_data, $query, $query_time, $query_callstack, $query_start) {
// Customize $query_data according to your needs.
return $query_data;
}
// Add the filter
add_filter("log_query_custom_data", "weplugins_modify_log_query_custom_data_defaults", 10, 5);
Example 2: Removing the Hook
If you need to remove the filter for some reason, here’s how you can do it.
remove_filter("log_query_custom_data", "weplugins_modify_log_query_custom_data_defaults", 10, 5);
Ensure you use the same callback function name, priority, and number of arguments to successfully remove it.
Example 3: Conditional Data Modification
Adjust the $query_data conditionally based on your site’s needs.
function weplugins_conditional_modify_query_data($query_data, $query, $query_time, $query_callstack, $query_start) {
if ($query_time > 1) { // Example condition
$query_data['slow_query'] = true;
}
return $query_data;
}
add_filter("log_query_custom_data", "weplugins_conditional_modify_query_data", 10, 5);
