Create a database called image_upload and create a table called images with fields:
- id - int(11)
- image - varchar(100)
- image_text - text
Create a file called index.php and page the following code in it (the complete code):
index.php:
<?php
// Create database connection
$db = mysqli_connect("localhost", "root", "", "image_upload");
// Initialize message variable
$msg = "";
// If upload button is clicked ...
if (isset($_POST['upload'])) {
// Get image name
$image = $_FILES['image']['name'];
// Get text
$image_text = mysqli_real_escape_string($db, $_POST['image_text']);
// image file directory
$target = "images/".basename($image);
$sql = "INSERT INTO images (image, image_text) VALUES ('$image', '$image_text')";
// execute query
mysqli_query($db, $sql);
if (move_uploaded_file($_FILES['image']['tmp_name'], $target)) {
$msg = "Image uploaded successfully";
}else{
$msg = "Failed to upload image";
}
}
$result = mysqli_query($db, "SELECT * FROM images");
?>

<form method="POST" action="index.php" enctype="multipart/form-data">

</div>
<div>
<button type="submit" name="upload">POST</button>
</div>
</form>
</div>
</body>
</html>
And that's all.
Be sure to include the enctype in your form tag. Like this:
<form method="POST" action="index.php" enctype="multipart/form-data">
Without the attribute enctype="multipart/form-data", the image won't be uploaded. enctype is the encoding type that specifies how the form-data should be encoded when submitting the form. Without it file uploads won't work.
