Unable to post image and text to database. Receiving no errors - php

Question

Hey guys I am having issues with my php file which is supposed to allow a user to post a status along with a picture which is uploaded to a server and its path along with the username of the user is added to the db.
DB Colomns:
postID (A.I)
username
status
imagepostpath
timestamp (added automatically inserting a new entry)
extra info: I have changed the code from one of my already working ones, but when I attempt to test the PHP file with Postman my error is "[]".
I'm not too familiar with PHP so if you see that the mistake that I'm making is simple, please help me understand it :)
Here is my code:
<?php
//importing dbDetails file
require_once 'dbDetails.php';
//this is our upload folder
$upload_path = '000002/';
//Getting the server ip
$server_ip = gethostbyname(gethostname());
//creating the upload url
$upload_url = 'http://'.$server_ip.'/Users/Images/'.$upload_path;
//response array
$response = array();
if($_SERVER['REQUEST_METHOD']=='POST'){
//checking the required parameters from the request
if(isset($_POST['name']) and isset($_FILES['image']['name'])){
//connecting to the database
$con = mysqli_connect(HOST,USER,PASS,DB) or die('Unable to Connect...');
//getting name from the request
$name = $_POST['name'];
$status = $_POST['status'];
$timestamp = date('Y-m-d H:i:s');
//getting file info from the request
$fileinfo = pathinfo($_FILES['image']['name']);
//getting the file extension
$extension = $fileinfo['extension'];
//file url to store in the database
$file_url = $upload_url . getFileName() . '.' . $extension;
//file path to upload in the server
$file_path = $upload_path . getFileName() . '.'. $extension;
//trying to save the file in the directory
try{
//saving the file
move_uploaded_file($_FILES['image']['tmp_name'],$file_path);
$sql = "INSERT INTO `flare`.`tbl_user_feed` (`postID`, `username`, `status`, `imagepostpath`, `timestamp`) VALUES (NULL, '$name', '$status', '$file_url');";
//adding the path and name to database
if(mysqli_query($con,$sql)){
//filling response array with values
$response['error'] = false;
$response['name'] = $name;
$response['imagepostpath'] = $file_url;
}
//if some error occurred
}catch(Exception $e){
$response['error']=true;
$response['message']=$e->getMessage();
}
//displaying the response
echo json_encode($response);
//closing the connection
mysqli_close($con);
}else{
$response['error']=true;
$response['message']='Please choose a file';
}
}
/*
We are generating the file name
so this method will return a file name for the image to be upload
*/
function getFileName(){
$con = mysqli_connect(HOST,USER,PASS,DB) or die('Unable to Connect...');
$sql = "SELECT max(postID) as postID FROM tbl_user_feed";
$result = mysqli_fetch_array(mysqli_query($con,$sql));
mysqli_close($con);
if($result['postID']==null)
return 1;
else
return ++$result['postID'];
}
?>

Change these lines:
move_uploaded_file($_FILES['image']['tmp_name'],$file_path);
Your file path is always the same so old files are being overwritten by new...randomize it with md5()
$unix = time();
$file_path = $upload_path . getFileName() . md5($unix) . '.'. $extension;
then alter your query slightly
$sql = "INSERT INTO `flare`.`tbl_user_feed` (`postID`, `username`, `status`, `imagepostpath`, `timestamp`) VALUES (NULL, '$name', '$status', '$file_url', '$unix')";// remove the semicolon before last double quote and add value for 5th column
