PHP Insert img to database - php

Question

I want to insert some data to database by query in PHP. I have something like this.
$zp='INSERT INTO `user`(`name`, `password`, `avatar`) VALUES ("'.$_POST['login'].'","'.$_POST['password'].'")';
And i want to put in the third value
<img src="$file_name.$file_type"/>
But I have no idea how to write this in PHP query

You need to create an upload functionality, and to save only the path where you're images are stored.
Create a table in your database, with few column names: filepath, mime, size.
A little example: index.php:
if(isset($_FILES['file']['name'])){
$name = $_FILES['file']['name'];
$mime = $_FILES['file']['type'];
$size = $_FILES['file']['size'];
$tmp = $_FILES['file']['tmp_name'];
$path = 'uploads/' . $name; //maybe you should create the uploads/ folder before running the script
if(move_uploaded_file($tmp, $path)){
$db = new PDO('mysql:host=localhost;dbname=your_db_name','your_db_user','your_db_pass');
$stmt = $db->prepare('INSERT INTO your_table_name_here SET filepath=?,mime=?,size=?');
$stmt->execute([$path,$mime,$size]);
echo 'File uploaded successfully!';
}
}
?>
<form action="index.php" method="post" enctype="multipart/form-data">
<input type="file" name="file">
<input type="submit" name="submit" value="Upload">
</form>
Then you can grab all the saved paths, and add them as src attrbuite for your images.
//index.php
$stmt = $db->prepare('SELECT filepath FROM your_table_name_here');
$stmt->execute();
while($row = $stmt->fetch()){?>
<img src="<?php echo $row['filepath']; ?>" alt="image">
<?php }
But notice this is just a super simple script, for your learning purposes, and this code must not be used in production mode, as is not safe.
