Image uploading doesn't work - php

Question

So guys.. I want to upload an image to a certain folder name "uploads" and insert the name of that image on database, the problem is that he isn't uploading the image..
So i have this basic HTML code:
<form action="newimage.php" method="POST">
<div class="row">
<div class="col-md-6 col-sm-6 col-xs-12">
<div class="form-group">
<input type="file" name="pic" id="pic">
</div>
<button type="submit" class="btn btn-success">Submit</button>
</div>
</div>
</form>
And this is my PHP page
<?php
$mysqli = new mysqli("localhost", "root", "", "homepage");
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
$name = "somethinghere";
#do upload
$target_dir = "uploads";
$temp = explode(".", $_FILES["pic"]["name"]);
$newfilename = $target_dir . '/Foto-' . $name . '.' . end($temp);
if (move_uploaded_file($_FILES['pic']['tmp_name'], $newfilename) ) {
$productimage = 'Foto-' . $name . '.' . end($temp);
}
else
{
$productimage = '';
}
$sql = "INSERT INTO galeria_front (image_name) VALUES ('$productimage')";
if ($mysqli->query($sql) === TRUE) {
header("Location: galery.php");
} else {
echo "Error: " . $sql . "<br>" . $mysqli->error;
}
$mysqli->close();
?>
As you can see i have a conection which works, and tried to insert the productimage into the database table but for some reason , it's entering the else{} and making my productimage empty on the database which means the above upload isn't working.
P.S(Pardon me for any bad english)

Answer 1

try adding these
<form action="newimage.php" method="POST" enctype="multipart/form-data">
</form
Alter your script into this
<?php
$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
if(isset($_POST["submit"])) {
$check = getimagesize($_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.";
}
}
?>

Answer 2

you are missing enctype="multipart/form-data"
<form action="/process.php" method="post" enctype="multipart/form-data"></form>
