i don't know if this works for you, but try this :
open your contact-form-7/modules/text.php & add this function :
// remember to check function existance first
if ( ! function_exists( 'wpcf7_add_tag_generator' ) ) {
function wpcf7_add_tag_generator( $name, $title, $elm_id, $callback, $options = array() ) {
global $wpcf7_tag_generators;
$name = trim( $name );
if ( '' == $name )
return false;
if ( ! is_array( $wpcf7_tag_generators ) )
$wpcf7_tag_generators = array();
$wpcf7_tag_generators[$name] = array(
'title' => $title,
'content' => $elm_id,
'options' => $options );
if ( is_callable( $callback ) )
add_action( 'wpcf7_admin_footer', $callback );
return true;
}
}
note :
you can get function wpcf7_add_tag_generator from contact-form-7/includes/taggenerator.php in your plugin folder
