How to use dbdelta_insert_queries filter in WordPress

dbdelta_insert_queries filter

Queries filterable via this hook contain “INSERT INTO” or “UPDATE”.

To use the dbdelta_insert_queries filter, first you have to register it using add_filter. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.

We at WePlugins always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function modify_dbdelta_insert_queries_defaults which takes 1 parameter and we registered using add_filter. The first parameter dbdelta_insert_queries is the name of the hook, the second parameter modify_dbdelta_insert_queries_defaults is the name of the function which needs to be called, the third parameter is the priority of calling the hook if the same hook is used multiple times, and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometimes, you have to remove a registered hook so you can use remove_filter to remove the dbdelta_insert_queries filter.

Parameters

Below the 1 parameter is required to use this hook.

• $iqueries : (string[]) An array of dbDelta insert or update SQL queries.

Live Example

apply_filters( 'dbdelta_insert_queries', string[] $iqueries )

Below is an example of how you can use this hook.

Example 1

This example demonstrates how to modify the dbDelta insert queries.

    function weplugins_modify_dbdelta_insert_queries_defaults($iqueries) { 
        // Update the $iqueries variable according to your website requirements and return this variable. You can modify the $iqueries variable conditionally too if you want.
        return $iqueries; 
    }
    // add the filter
    add_filter( "dbdelta_insert_queries", "weplugins_modify_dbdelta_insert_queries_defaults", 10, 1 );
    

Example 2

To remove a hook callback, use the example below.

    remove_filter( "dbdelta_insert_queries", "weplugins_modify_dbdelta_insert_queries_defaults", 10, 1 );
    

Please make sure to provide the same callback function name, priority, and number of arguments while removing the hook callback.

Example 3

This example shows conditional modification of queries based on specific requirements.

    function weplugins_modify_dbdelta_insert_queries_conditionally($iqueries) { 
        if (some_condition) {
            // Modify $iqueries based on a condition
        }
        return $iqueries; 
    }
    // add the filter
    add_filter( "dbdelta_insert_queries", "weplugins_modify_dbdelta_insert_queries_conditionally", 10, 1 );
