request_filesystem_credentials filter
Returning anything other than an empty string will effectively short-circuit output of the filesystem credentials form, returning that value instead.
To use request_filesystem_credentials 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 Flipper Code, 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_request_filesystem_credentials_defaults which takes 7 parameters and we registered using add_filter. The first parameter request_filesystem_credentials is name of the hook, The second parameter modify_request_filesystem_credentials_defaults is name of the function which need to be called, third parameter is the priority of calling the hook if same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.
Sometime, you have to remove a registered hook so you can use remove_filter to remove request_filesystem_credentials filter.
Parameters
- $credentials : (mixed) Credentials to return instead. Default empty string.
- $form_post : (string) The URL to post the form to.
- $type : (string) Chosen type of filesystem.
- $error : (bool|WP_Error) Whether the current request has failed to connect, or an error object.
- $context : (string) Full path to the directory that is tested for being writable.
- $extra_fields : (array) Extra POST fields.
- $allow_relaxed_file_ownership : (bool) Whether to allow Group/World writable.
Below are the 7 parameters are required to use this hook.
Live Example
apply_filters( 'request_filesystem_credentials', mixed $credentials, string $form_post, string $type, bool|WP_Error $error, string $context, array $extra_fields, bool $allow_relaxed_file_ownership )
Below is an example how you can use this hook.
function modify_request_filesystem_credentials_defaults($credentials, $form_post, $type, $error, $context, $extra_fields, $allow_relaxed_file_ownership) {
// Update the $credentials variable according to your website requirements and return this variable. You can modify the $credentials variable conditionally too if you want.
return $credentials;
}
// add the filter
add_filter( "request_filesystem_credentials", "modify_request_filesystem_credentials_defaults", 10, 7 );
To remove a hook callback, use the example below.
remove_filter( "request_filesystem_credentials", "modify_request_filesystem_credentials_defaults", 10, 7 );
Please make sure provide the same callback function name, priority and number of arguments while removing the hook callback.
