自动创建ID时，如何在其他表中使用ID的值

Question

我有这两个表palle_tb和csvName我试图使用palle_tb到我的csvName中的FK_Name 的 id ，但这些表已连接，但我在FK_Name中没有任何值。

我很确定我应该在':FK_Name' =>里面添加一个变量，但是不知道要写什么，因为我已经有了FK_Name INT(11), FOREIGN KEY (FK_Name) REFERENCES palle_tb(id),

这是我的代码：

public function createPalleTable($latest_filename){
    return $this->db->toList("CREATE TABLE IF NOT EXISTS `palle_tb`(
        id INT(11) AUTO_INCREMENT PRIMARY KEY,
        Palle_nr VARCHAR(50), 
        Varenummer VARCHAR(50), 
        Ordre_nummer VARCHAR(50), 
        Operatoer VARCHAR(50), 
        Maskine_nr VARCHAR(50), 
        Raavare_batch_nr VARCHAR(50), 
        Dato_ur_stillet VARCHAR(50), 
        Klokke_fuldsvejst VARCHAR(50), 
        Fuldstoebning_af_klokke VARCHAR(50),
        Afgratning_af_overflade VARCHAR(50), 
        Vaegt DECIMAL(10,2))
      ");
}

public function insertPalleTable($latest_filename ,$palledata){
    return $this->db->toList("INSERT INTO `palle_tb` (`Palle_nr`, `Varenummer`, `Ordre_nummer`, `Operatoer`, `Maskine_nr`,
     `Raavare_batch_nr`, `Dato_ur_stillet`,`Klokke_fuldsvejst`,`Fuldstoebning_af_klokke`,`Afgratning_af_overflade`,`Vaegt`)
    VALUES (:Palle_nr, :Varenummer, :Ordre_nummer, :Operatoer, :Maskine_nr, :Raavare_batch_nr, :Dato_ur_stillet,
     :Klokke_fuldsvejst, :Fuldstoebning_af_klokke, :Afgratning_af_overflade, :Vaegt)",
        [
        ':Palle_nr' => $palledata[0],
        ':Varenummer'=> $palledata[1],
        ':Ordre_nummer'=> $palledata[2],
        ':Operatoer'=> $palledata[3],
        ':Maskine_nr'=> $palledata[4],
        ':Raavare_batch_nr'=> $palledata[5],
        ':Dato_ur_stillet'=> $palledata[6],
        ':Klokke_fuldsvejst'=> $palledata[7],
        ':Fuldstoebning_af_klokke'=> $palledata[8],
        ':Afgratning_af_overflade'=> $palledata[9],
        ':Vaegt'=> $palledata[10]
        ]
    );
}
/*The idea with the functions under this is that it creates a table with the Name of the data only and creates a foreign key to connect them*/
public function createCsvTable(){
    return $this->db->toList("CREATE TABLE IF NOT EXISTS `CsvName`(
        id INT(11) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
        FK_Name INT(11),
        FOREIGN KEY (FK_Name) REFERENCES palle_tb(id),
        Name VARCHAR(50))
      ");
}
public function insertCsvData($myArray){
    $this->db->query("INSERT INTO CsvName (Name,FK_Name)
    VALUES (:Name,:FK_Name)",
        [
        ':Name' => $myArray[0], /*This array contains all my data, but when i add the [0] it only takes the Name*/
        ':FK_Name' => /*This should contain the id from the palle_tb i need help with how to get that*/
        ]
    );
}

如果您需要按钮，那么这里是该代码。 我需要它是自动的，所以用外键进行选择不会起作用。

if (isset($_POST['btn-upload'])){

    copy("$sourcepath/$latest_filename","$copy/$latest_filename");
    // Here i split the csv file, from second line. and using the first and fourth lines as the headers.
    if (($openfile = fopen("$copy/$latest_filename", "r")) !== false) {

        $header1 = fgetcsv($openfile, 1000, ";"); // consume, but don't use

        $csv->createPalleTable($latest_filename);
        $csv->insertPalleTable($latest_filename, array_map("toNumber", fgetcsv($openfile, 1000, ";")));

        $delimiting_row = fgetcsv($openfile, 1000, ";"); // consume, but don't use 
        $header2 = fgetcsv($openfile, 1000, ";"); // consume, but don't use

        while($row = fgets($openfile)){  
            // can parse further $row by usingstr_getcsv

            $myArray = explode(';', $row);
            $myArray = array_map("utf8_encode", $myArray);
            $myArray = array_map("toNumber", $myArray);

            echo'<pre>';
            print_r($myArray);
            echo'</pre>';
            $csv->createCsvTable();
            $csv->insertCsvData($myArray);
        }
    }
    fclose($openfile);
}

我是这样做的。

  public function createGodTable()
{
    return $this->db->toList("CREATE TABLE IF NOT EXISTS `Angle`(
        id INT(11) AUTO_INCREMENT PRIMARY KEY,
