I have reduced the code in both files to try and figure out what is going on.
In my first file loginuser.php, I am running the following lines:
<?php
session_start();
$_SESSION['user_id'] = "test";
// more code follows; nothing else that involved user id or session
To double check that $_SESSION variable is indeed set, I ran the following modified approach:
<?php
session_start();
$_SESSION['user_id'] = "test";
$response['success'] = false;
$response['message'] = $_SESSION['user_id'];
echo json_encode($response);
exit;
When $response['success'] is false, the message is printed. So at this point I know that the $_SESSION variable was indeed set and I am getting a body response.
In my second file addrelease.php, I then run the following lines to check if I am seeing the session variable even before I do anything else:
<?php
session_start();
$response['message'] = $_SESSION['user_id'];
// more code would follow but again i will force message to pop and exit
$response['success'] = false;
echo json_encode($response);
exit;
The app will toast "Error, no response" if there is no body provided in the response (I am using retrofit) and this is exactly what happens. Given this, I know that addrelease.php does not even echo the response.
To confirm my suspicion that something is going on with the $_SESSION variable, I replaced $_SESSION['user_id'] in addrelease.php with "test2" and now I am getting a body with the message that I forced.
Most posts that I am finding seem to resolve their issue by ensuring the session_start() is the very first thing that is called and doubling checking the session_save_path. I have looked at both of these and can't find any issues.
Hoping someone can help me, thanks in advance!
P.S. this is all new to me so please excuse if I am making a very basic mistake somewhere.
How exactly are you calling your addrelease.php script? Sounds like whatever is making that background(?) request, is probably not sending the session id.
Here is how i understand it to happen
NewReleaseActivity.java
Call<ReleaseModel> releaseModelCall = apiInterface.addRelease(
owner.trim(),
binding.textInputEditTrackName.getText().toString().trim(),
binding.textInputEditArtist.getText().toString().trim(),
label.trim(),
binding.textInputEditISRC.getText().toString().trim(),
binding.textInputEditUPC.getText().toString().trim(),
releaseDate,
TextUtils.join(",", buttonStates),
percentage
);
ApiInterface.java
@FormUrlEncoded
@POST("addrelease.php")
Call<ReleaseModel> addRelease(@Field("owner") String owner,
@Field("track_name") String trackName,
@Field("artist") String artist,
@Field("label") String label,
@Field("isrc") String isrc,
@Field("upc") String upc,
@Field("release_date") LocalDate date,
@Field("button_states") String buttonStates,
@Field("release_progress") float releaseProgress);
Additional Context
My goal is to get the session variable to bind with owner in my prepared statement:
$sql = "INSERT INTO releases (owner, track_name, artist,
label, isrc, upc,
release_date, button_states, progress) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)";
$stmt->bind_param("ssssssssd",
/*$_POST["owner"]*/ $_SESSION['user_id'],
$_POST["track_name"],
$_POST["artist"],
$_POST["label"],
$_POST["isrc"],
$_POST["upc"],
$_POST["release_date"],
$_POST["button_states"],
$_POST["release_progress"]
);
