New Post form wont write to DB - php

Question

I got this form for adding new posts and i can't get it to write to DB. I debugged it as much as i can and when i try to add i don't get any errors but also i don't see the post stored in my DB. Am i missing something? Code:
-This is the form
<form method = "post" action = "vpost.php" enctype="multipart/form-data">
<label>
<h5>Наслов</h5>
<input type="text" name="title" placeholder="Enter title" value = "<?php if(isset($_POST['title'])) { echo $post_title; } ?>">
</label>
<label>
<h5>Адреса</h5>
<input type="text" name="address" placeholder="Enter address" value = "<?php if(isset($_POST['address'])) { echo $post_address; } ?>">
</label>
<hr>
<label>

-This is the validation and writing to base file
<?php

require("GUMP-master/gump.class.php");

$_POST = $gump->sanitize($_POST);
$gump->validation_rules(array(

$post_author = $_SESSION['firstname'];
}
$post_date = date('Y-m-d');
$image = $_FILES['image']['name'];
$ext = $_FILES['image']['type'];
$validExt = array ("image/gif", "image/jpeg", "image/pjpeg", "image/png", "image/jpg");
if (empty($image)) {
echo "<script>alert('Attach an image');</script>";
}
else if ($_FILES['image']['size'] <= 0 || $_FILES['image']['size'] > 1024000 )
{
echo "<script>alert('Image size is not proper');</script>";
}
else if (!in_array($ext, $validExt)){
echo "<script>alert('Not a valid image');</script>";
}
else {
$folder = 'postpics/';
$imgext = strtolower(pathinfo($image, PATHINFO_EXTENSION) );
$picture = rand(1000 , 1000000) .'.'.$imgext;
if(move_uploaded_file($_FILES['image']['tmp_name'], $folder.$picture)) {
$query = "INSERT INTO posts (title,address,price,type,year_built,parking,sqmeter,heat,date,image) VALUES ('$post_title' , '$post_address' , '$post_price' , '$post_type' , '$post_yearbt' , '$post_parking', '$post_sqmeter','$post_heat','$post_date','$picture')";
$result = mysqli_query($conn , $query) or die(mysqli_error($conn));
if (mysqli_affected_rows($conn) > 0) {
echo "<script> alert('Posted!');
window.location.href='index.php';</script>";
}
else {
"<script> alert('Error while posting..try again');</script>";
}
}
}
}
}
?>
First i thought that i might be missing a field in my DB but i rechecked and i created the table again. If needed i will post a picture of my posts table and the columns.

Your issue I suspect is you are checking if your image file has been uploaded with $_POST['image']. This isn't how PHP handles file uploads - they are stored in $_FILES instead so your isset($_POST['image'] == false.
This should work:
<?php
include('includes/general.php');
if (isset($_POST['title']) && isset($_POST['address']) && isset($_POST['price']) &&
isset($_POST['type']) && isset($_POST['year_built']) && isset($_POST['parking']) &&
isset($_POST['sqmeter']) && isset($_POST['heat']) && isset($_POST['image']) && count($_FILES) > 0)
{
//Properly sanitise and validate your inputs and do what else you need to do
}
Tip: if you ever find a PHP file just isn't doing what it should be, a conditional statement you're using to validate data is a very likely culprit. Try debugging by putting die('OK up to here'); within your if blocks to pinpoint whether code is being executed.
For example, in your code if you had debugged with:
<?php
include('includes/general.php');
if (isset($_POST['title']) && isset($_POST['address']) && isset($_POST['price']) &&
isset($_POST['type']) && isset($_POST['year_built']) && isset($_POST['parking']) &&
isset($_POST['sqmeter']) && isset($_POST['heat']) && isset($_POST['image'])) {
die('OK up to here');
//Your code
}
Then the OK up to here message wouldn't have been displayed in your output and you would know there was a problem with the conditional statement.
