在控制器symfony3中以一对一的关系自动设置关系值

A little background information. I have two entities that have a Bidirectional relationship: essentially, an application form can have exactly one recommendation form. When a recommender fills out a form, I would like to have it automatically, and only select the related application form (protect other user's data), based on a specific code, which they enter on a custom formpage I created. I'm not sure how it happened, but I got it to work once, but for some unknown reason, it stopped and is adding "NULL" for the applicant form id in the recommendation form in my database. I'll include all info that I can:

RecommendationForm Entity:

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * RecommendationForm
 *
 * @ORM\Table(name="recommendation_form")
 * @ORM\Entity(repositoryClass="AppBundle\Repository\RecommendationFormRepository")
 */
class RecommendationForm
{
    /**
     * @var int
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * One RecommendationForm has One ApplicantForm.
     * @ORM\OneToOne(targetEntity="ApplicantForm", inversedBy="recommendation_form")
     * @ORM\JoinColumn(name="applicant_form_id", referencedColumnName="id")
     */
    private $applicant_form;

    //....

    public function __construct($applicant_form) {
        date_default_timezone_set('America/New_York');

        $this->applicant_form = $applicant_form;

        $this->submitDate = new \DateTime("now");
    }


    /**
     * Get id
     *
     * @return integer
     */
    public function getId()
    {
        return $this->id;
    }


    // /**
    //  * Set applicantForm
    //  *
    //  * @param integer $applicant_form
    //  *
    //  * @return RecommendationForm
    //  */
    // public function setApplicantForm($applicant_form)
    // {
    //     $this->applicant_form = $applicant_form;

    //     return $this;
    // }

    /**
     * Get applicantForm
     *
     * @return integer
     */
    public function getApplicantForm()
    {
        return $this->applicant_form;
    }

//....
}

ApplicantForm Entity:

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use chriskacerguis\Randomstring\Randomstring;

/**
 * ApplicantForm
 *
 * @ORM\Table(name="applicant_form")
 * @ORM\Entity(repositoryClass="AppBundle\Repository\ApplicantFormRepository")
 */
class ApplicantForm
{
    /**
     * @var int
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * One ApplicantForm has One RecommendationForm.
     * @ORM\OneToOne(targetEntity="RecommendationForm", mappedBy="applicant_form")
     */
    private $recommendation_form;

    /**
     * @var string
     *
     * @ORM\Column(name="accessCode", type="string", length=75, unique=true)
     */
    private $accessCode;

    //....

    public function __construct() {

        $random = new \chriskacerguis\Randomstring\Randomstring();

        $this->accessCode = $random->generate(15, true);
    }

//...
}

I have scoured all over the internet and just can't find an answer or figure out how it stopped working.

    I figured out what I changed and I'll put the answer here in case anyone wanted to do it. I was playing around with the different form methods and changed the form's original method from "GET" to POST (and all calls to the value in the controller were changed from "GET" to "POST"). On a whim, I changed it back and it's working again. I'm pretty sure I changed it because I didn't like that get methods put the query string in the address bar and mistakenly assumed that changing the method to post would fix it. If anyone has a recommendation of what to use instead of that, I welcome all suggestions.

    Not working controller:

    //...
    public function newAction(Request $request)
    {
        if(isset($_POST["accessCodeSS"])){
    
            $this->accessCode = $_POST["accessCodeSS"];
    //...
    }
    

    Correct working controller:

    public function newAction(Request $request)
    {
        if(isset($_GET["accessCodeSS"])){
    
            $this->accessCode = $_GET["accessCodeSS"];
    //...
    }
    

    Correct form (index.html.twig):

    <form action="{{ path('recommendation_form_new') }}" method="GET">
        <input type="email" name="email" placeholder="Email Address">
        <input type="password" name="accessCodeSS" placeholder="Access Code">
        <input type="submit" name="submit" value="Submit">
    </form>
