Inserting only the specific column from the csv using load data local file

Question

I'm using mysql LoadDataLocalFile to enter the data from my csv file to my db. My query works when I don't have to choose any columns but this time I have to.

Suppose I have this content in my csv:

move_doc_number |   sku |   slot_code | qty|    store_id |  so_no | date
210               900496    PCK00001    2         20        10472   140509

At the above csv, the only column I want to be inserted in my table is the so_no and move_doc_number.

And these is my table structure

move_doc_number | so_no

This is my command in loading the csv to my db

$query = "LOAD DATA LOCAL INFILE ".$this->pdo->quote($csv_dir)." 
                    IGNORE 
                    INTO TABLE `$table`
                    FIELDS TERMINATED BY ".$this->pdo->quote($this->fieldSeparator)."
                    LINES TERMINATED BY ".$this->pdo->quote($this->lineSeparator) . " " .$columns;

How can I accomplish this?
