Do you wish to add a picture to the database? Most software companies transfer the uploaded information to a listing and save their path to the database.
Earlier, we noticed code for storing uploaded photographs to the database utilizing MySQL BLOB fields. BLOB(Binary Massive Knowledge Object) is likely one of the MySql knowledge varieties. It may have the file binary knowledge. MySQL helps 4 forms of BLOB datatype as follows.
View demo
- TINYBLOB
- BLOB
- MEDIUMBLOB
- LONGBLOB
For this instance, we created one of many above BLOB fields in a MySQL database to see the way to add a picture. Added to that, this code will fetch and BLOB knowledge from the database and show the picture to the browser.
Database script
Earlier than operating this instance, create the required database construction in your server.
CREATE TABLE photographs ( id INT(11) AUTO_INCREMENT PRIMARY KEY, picture LONGBLOB NOT NULL );
HTML type with a picture add possibility
This can be a standard file add type with a file enter. This discipline restricts the file kind to decide on solely the pictures utilizing the settle for attribute.
On submitting this manner, the add.php receives the posted file binary knowledge on the server aspect.

This PHP script will get the chosen file knowledge with the $_FILES array. This array accommodates the bottom title, non permanent supply path, kind, and extra particulars.
With these particulars, it performs the file add to the database. The steps are as follows,
- Validate file array will not be empty.
- Retrieve the picture file content material utilizing file_get_contents($_FILES[“image”][“tmp_name”]).
- Put together the insert and bind the picture binary knowledge to the question parameters.
- Execute insert and get the database report id.
<?php
// MySQL database connection settings
$servername = "localhost";
$username = "root";
$password = "admin123";
$dbname = "phppot_image_upload";
// Make connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Examine connection and throw error if not out there
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
// Examine if a picture file was uploaded
if (isset($_FILES["image"]) && $_FILES["image"]["error"] == 0) {
$picture = $_FILES['image']['tmp_name'];
$imgContent = file_get_contents($picture);
// Insert picture knowledge into database as BLOB
$sql = "INSERT INTO photographs(picture) VALUES(?)";
$assertion = $conn->put together($sql);
$statement->bind_param('s', $imgContent);
$current_id = $statement->execute() or die("<b>Error:</b> Drawback on Picture Insert<br/>" . mysqli_connect_error());
if ($current_id) {
echo "Picture uploaded efficiently.";
} else {
echo "Picture add failed, please attempt once more.";
}
} else {
echo "Please choose a picture file to add.";
}
// Shut the database connection
$conn->shut();
Fetch picture BLOB from the database and show to UI
This PHP code prepares a SELECT question to fetch the picture BLOB. Utilizing the picture binary from the BLOB, it creates the info URL. It applies PHP base64 encoding on the picture binary content material.
This knowledge URL is about as a supply of an HTML picture ingredient under. This script reveals the just lately inserted picture on the display. We are able to additionally present a picture gallery of all of the BLOB photographs from the database.
<?php
// Retrieve the uploaded picture from the database
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "phppot_image_upload";
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$consequence = $conn->question("SELECT picture FROM photographs ORDER BY id DESC LIMIT 1");
if ($consequence && $result->num_rows > 0) {
$row = $result->fetch_assoc();
$imageData = $row['image'];
echo '<img src="knowledge:picture/jpeg;base64,' . base64_encode($imageData) . '" alt="Uploaded Picture" type="max-width: 500px;">';
} else {
echo 'No picture uploaded but.';
}
$conn->shut();
?>
