Php is uploading images but not inserting in database - php

Question

I'm developing a back end for my blog but the code to upload images isn't working as expected.
When i submit it uploads the image and moves it to the designated folder but in the database there is no record inserted. Here is the php for uploading
<?php
session_start();
include('Connections/conn.php');
if (!isset($_SESSION['userid'])) {
header("location:index.php");
}
$suc=" ";
$writer=$_SESSION['my_username'];
if(isset($_POST['submit']))
{
error_reporting(E_ALL ^ E_NOTICE);
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
// Check if file already exists
if (file_exists($target_file)) {
echo "Sorry, file already exists.";
$uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
echo "Sorry, your file is too large.";
$uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
$title=$_POST['title'];
$intro=$_POST['intro'];
$body=$_POST['body'];
$keywords=$_POST['keywords'];
$date=$_POST['date'];
$fileToUpload=$_POST['fileToUpload'];
$sql2="Insert into articles(title,intro,body,keywords,date,writer,fileToUpload)VALUES('$title','$intro','$body','$keywords','$date','$writer','$target_file')"or die(mysqli_error());
$result2 = mysqli_query($db_conn, $sql2);
$suc=" <div class='alert alert-success'>
<span><b>Success</b>: New article posted successfully!</span>
</div>";
}
?>
And here is the form
<form method="POST" action"<?php echo $_SERVER['PHP_SELF']; ?>" enctype="multipart/form-data">
<div class="form-group">
<label>Title</label>
<input type="text" id="title" name="title" class="form-control" required/>
</div>
<div class="form-group">
<label>Intro</label>
<textarea id="intro" name="intro" class="form-control" required></textarea>
</div>
<div class="form-group">
<label>Enter keyword tags</label><br/>
<div>
<input type="text" id="keywords" name="keywords" class="tagsinput" required/>
</div>
</div>
<div class="form-group">
<label>Date</label><br/>
<div>
<div class="input-group">
<span class="input-group-addon"><span class="fa fa-calendar"></span></span>
<input type="text" id="date" name="date" class="form-control datepicker" placeholder="Select Date" required>
</div>
<span class="help-block">Click on input field to select date</span>
</div>
<div class="form-group">
<div>
<label>Picture</label>
<input type="file" multiple class="file" data-preview-file-type="any" name="fileToUpload" id="fileToUpload"/>
</div>
</div>
<div>
<div class="block">
<p>Type the content below, note that you can extend the height of the editor by dragging the bottom border.</p>
<textarea class="summernote" id="body" name="body" placeholder="Enter the body text" required>
</textarea>
</div>
</div>
</div>
<div class="form-group">
<div class="col-md-6">
<button class="btn btn-danger btn-block" type="reset">Reset</button>
</div>
<div class="col-md-6">
<button class="btn btn-info btn-block" type="submit" name="submit" value="submit">Publish Article</button>
</div>
</div>
</form>

Answer 1

Replace
$fileToUpload=$_POST['fileToUpload'];
with
$fileToUpload=$_FILES['fileToUpload']['name'];

Answer 2

Try this
$sql2="INSERT INTO articles(title,intro,body,keywords,date,writer,fileToUpload)VALUES('$title','$intro','$body','$keywords','$date','$writer','$target_file')");
if (!mysqli_query($db_conn, sql2))
{
echo("Error description: " . mysqli_error($db_conn));
}
else{
echo "Inserted";
}
and my opinion is add the insert code after move_uploaded_file get success
