How to? Insert current date from Android into mySQL database using Retrofit2

Question

Trying to insert Current date from android to mysql via Retrofit. The date is showing in the mysql database as 0000-00-00. I've read over multiple threads on SO on this topic and tried to apply the answers but so far I have not been successful. Please see the below code snippets for context.

PHP CODE:

<?php

include('conn.php');

$userId = $_POST['userId'];
$moodBefore = $_POST['moodBefore'];
$automaticThought = $_POST['automaticThought'];
$distortions = $_POST['distortions'];
$challengeThought = $_POST['challengeThought'];
$alternativeThought = $_POST['alternativeThought'];
$moodAfter = $_POST['moodAfter'];
$posted = $_POST['posted'];

$insert = "INSERT INTO Cbt ( userId, moodBefore,   automaticThought, distortions, challengeThought, alternativeThought, moodAfter, posted) VALUES
('$userId','$moodBefore', '$automaticThought', '$distortions', '$challengeThought', '$alternativeThought', '$moodAfter', '$posted')";

  $resultinsert = $conn -> query($insert);
              if(!$resultinsert){
                  echo $conn->error;
        }
 ?>

RETROFIT API CODE:

public interface Api {

    @FormUrlEncoded
    @POST("insert.php")
    Call<ResponseBody> insertLog(
            @Field("userId") int userId,
            @Field("moodBefore") int moodBefore,
            @Field("automaticThought") String automaticThought,
            @Field("distortions") int distortions,
            @Field("challengeThought") String challengeThought,
            @Field("alternativeThought") String alternativeThought,
            @Field("moodAfter") int moodAfter,
            @Field("posted") String date
    );

JAVA CODE:

String posted = new SimpleDateFormat("ddMMyyyy").format(new Date());

case R.id.nextBtnMoodPage:
                if (hasSelected) {

                    Call<ResponseBody> call = RetrofitClient
                            .getInstance()
                            .getApi()
                            .insertLog(userId, moodBefore, automaticThoughtString, distortions, challengeThoughtString, alternativeThoughtString, moodAfter, posted);

                    call.enqueue(new Callback<ResponseBody>() {.....and so on

I would like the date to insert succesfully and not show 0000-00-00 If I could also make the date show as DD-MM-YYYY that would be even better.

Answer 1

This worked in the Java code, all other parts of the code stay the same

private Date currentDate() {
    final Calendar cal = Calendar.getInstance();
    cal.add(Calendar.DATE, 0);
    return cal.getTime();
}

DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd");
String posted = dateFormat.format(currentDate());
