PHP Image upload not working, no data inserted into MySQL - php

Question

I'm just creating a simple image upload to MySQL
<form method="post" action="quanly.php" class="form-group justify-content-center" enctype="multipart/form-data">
<div class="custom-file mb-3">
<input type="file" class="custom-file-input" id="image" name="image">
<label class="custom-file-label" for="customFile">Choose file</label>
</div>
<div class="col text-center">
<button type="submit" name="submit" id="add_btn" class="btn btn-primary mb-2"> <i class="fas fa-plus"></i>Submit</button>
</div>
</form>
And my php code:
$image = addslashes(file_get_contents($_FILES['image']['name']));
$query = "INSERT INTO tasks (image) VALUES ('$image')";
mysqli_query($db, $query); //db is the mysql connection
The image in MySQl is LONGBLOB.
THE PROBLEM: when I try to submit an image, no data was in the database

Answer 1

Remove file_get_contents from image tags.
$image = addslashes($_FILES['image']['name']);
$query = "INSERT INTO tasks (image) VALUES ('$image')";
mysqli_query($db, $query); //db is the mysql connection

Answer 2

<?php
$target_dir = "quanly/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($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;
}
}
?>
$target_dir = "quanly/" - specifies the directory where the file is going to be placed.
$target_file specifies the path of the file to be uploaded
$uploadOk=1 is not used yet (will be used later)
$imageFileType holds the file extension of the file (in lower case)
Next, check if the image file is an actual image or a fake image
Try this..
