Check Your Own Form Submissions With Akismet
Adds a wpide_akismet_is_spam() helper that sends a name, email and message from any custom form to Akismet and tells you whether it looks like spam, so your hand-built forms get the same protection as comments.
Opens WPIDE on
Code
if ( ! function_exists( 'wpide_akismet_is_spam' ) ) {
function wpide_akismet_is_spam( array $fields ) {
if ( ! class_exists( 'Akismet' ) || ! Akismet::get_api_key() ) {
return false;
}
$request = array(
'blog' => home_url(),
'blog_lang' => get_locale(),
'blog_charset' => get_option( 'blog_charset' ),
'user_ip' => isset( $_SERVER['REMOTE_ADDR'] ) ? sanitize_text_field( wp_unslash( $_SERVER['REMOTE_ADDR'] ) ) : '',
'user_agent' => isset( $_SERVER['HTTP_USER_AGENT'] ) ? sanitize_text_field( wp_unslash( $_SERVER['HTTP_USER_AGENT'] ) ) : '',
'referrer' => wp_get_raw_referer() ? wp_get_raw_referer() : '',
'permalink' => wp_get_referer() ? wp_get_referer() : home_url( '/' ),
'comment_type' => 'contact-form',
'comment_author' => isset( $fields['name'] ) ? (string) $fields['name'] : '',
'comment_author_email' => isset( $fields['email'] ) ? (string) $fields['email'] : '',
'comment_content' => isset( $fields['message'] ) ? (string) $fields['message'] : '',
);
$response = Akismet::http_post( Akismet::build_query( $request ), 'comment-check' );
return is_array( $response ) && isset( $response[1] ) && 'true' === trim( $response[1] );
}
}Notes
Call wpide_akismet_is_spam( array( 'name' => ..., 'email' => ..., 'message' => ... ) ) in your form handler; it returns false when Akismet is missing or unreachable, so submissions are never lost.
