How to insert data from a table to another table

Question

I am using this auto complete form, that gets the data from 1 table,

now i am using that form to insert data from its table to another table.

here is my SQL for the inserting into the table "products"

$image = addslashes(file_get_contents($_FILES['prod_pic']['tmp_name']));
$sql="INSERT INTO `inventory` (`prod_brand`,`prod_name`,`prod_category`,`prod_price`,`prod_desc`,`prod_quantity`,`prod_pic`)
VALUES 
('$_POST[prod_brand]','".mysql_real_escape_string($_POST['prod_name'])."','$_POST[prod_category]' ,'$_POST[prod_price]',
    '".mysql_real_escape_string($_POST['prod_desc'])."','$_POST[prod_quantity]','{$image}')";

the prod_category is the column i need to fill. I have data from the table named "categories" with column name "categories"

so how do i input the data from categories to the column = prod_category in the products table?

As i understand in POST['prod_category '] contain string, like you have text input. The best way to do what you need - is change category for select in html, like this

        <select>
    foreach(categories as $category){ 

    <option value='category->id' >category1->name </option>
}
</select>

Then you will get in post category id from the table named "categories" If you dont like it your should replace '$_POST[prod_category]' from youre query to subquery

select id from categories where categories = '$_POST[prod_category]'
