Hello All i want help please
anyone have sql for
Attributes Osclass Plugin​
Car Make, model, years etc...

Not Car_Attributes 
 

This sql creates tables but you have to fill conditions yourself or do you want someone else to fill it for you?
CREATE TABLE /*TABLE_PREFIX*/t_item_car_vehicle_type_attr (
  pk_i_id INT(2) UNSIGNED NOT NULL,
  fk_c_locale_code CHAR(5) NOT NULL,
  s_name VARCHAR(255),

  PRIMARY KEY (pk_i_id, fk_c_locale_code),
  FOREIGN KEY (fk_c_locale_code) REFERENCES /*TABLE_PREFIX*/t_locale (pk_c_code) ON DELETE CASCADE ON UPDATE CASCADE
) ENGINE=InnoDB DEFAULT CHARACTER SET 'UTF8' COLLATE 'UTF8_GENERAL_CI';

CREATE TABLE /*TABLE_PREFIX*/t_item_car_make_attr (
  pk_i_id INT(2) UNSIGNED NOT NULL AUTO_INCREMENT,
  s_name VARCHAR(255),

  PRIMARY KEY (pk_i_id)
) ENGINE=InnoDB DEFAULT CHARACTER SET 'UTF8' COLLATE 'UTF8_GENERAL_CI';

CREATE TABLE /*TABLE_PREFIX*/t_item_car_model_attr (
  pk_i_id INT(2) UNSIGNED NOT NULL AUTO_INCREMENT,

I would say I saw such file somewhere here in forums...

Good afternoon!I'm sorry if the question is not quite for you. And this is not a question of error. But it concerns the car_attributes plugin. Please tell me if it's not difficult. If I want to add a couple more criteria to the filter to search for ads. I create corresponding windows and functions for this. How to make the search carried out taking into account the data of these windows? In which function do I need to add the criteria I have added? Thank you in advance for your help.

you must add those fields to form first and then manage them when form is submitted to add proper filters in database layer.

Thank you for your promptness. I created the forms themselves. I also wrote functions for them. I just can't figure out which function processes the forms and sends the data to the database?

These functions are hooked via "posted_item" or "edited_item" hooks.
