$image_text = mysqli_real_escape_string($db, $_POST['image_text']);
// image file directory
$target = "images/".basename($image);
$sql = "INSERT INTO images (image, image_text) VALUES ('$image', '$image_text')";

Example 2: how to place the path of an uploaded image in a database on an html file input
<?php
include("config.php");
if(isset($_POST['but_upload'])){
$name = $_FILES['file']['name'];
$target_dir = "upload/";
$target_file = $target_dir . basename($_FILES["file"]["name"]);
// Select file type
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
// Valid file extensions
$extensions_arr = array("jpg","jpeg","png","gif");
// Check extension
if( in_array($imageFileType,$extensions_arr) ){
// Convert to base64
$image_base64 = base64_encode(file_get_contents($_FILES['file']['tmp_name']) );
$image = 'data:image/'.$imageFileType.';base64,'.$image_base64;
// Insert record
$query = "insert into images(image) values('".$image."')";
mysqli_query($con,$query);
// Upload file
move_uploaded_file($_FILES['file']['tmp_name'],$target_dir.$name);
}
}
?>
