Example 1: how to upload image in php and store in database and folder
// Get the name of images
$Get_image_name = $_FILES['image']['name'];
// image Path
$image_Path = "images/".basename($Get_image_name);
$sql = "INSERT INTO student_table (imagename, contact) VALUES ('$Get_image_name', 'USA')";
// Run SQL query
mysqli_query($conn, $sql);
if (move_uploaded_file($_FILES['image']['tmp_name'], $image_Path)) {
echo "Your Image uploaded successfully";
}else{
echo "Not Insert Image";
}
}
Example 2: php upload file
<?php
if(isset($_FILES['image'])){
$errors= array();
$file_name = $_FILES['image']['name'];
$file_size =$_FILES['image']['size'];
$file_tmp =$_FILES['image']['tmp_name'];
$file_type=$_FILES['image']['type'];
$file_ext=strtolower(end(explode('.',$_FILES['image']['name'])));
$extensions= array("jpeg","jpg","png");
if(in_array($file_ext,$extensions)=== false){
$errors[]="extension not allowed, please choose a JPEG or PNG file.";
}
if($file_size > 2097152){
$errors[]='File size must be excately 2 MB';
}
if(empty($errors)==true){
move_uploaded_file($file_tmp,"images/".$file_name);
echo "Success";
}else{
print_r($errors);
}
}
?>
Example 3: basic code for file upload in php
//This is the minimal code for an image upload for first time learners
//html portion
<!DOCTYPE html>
<html>
<head>
<title>ImageUpload</title>
</head>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data">
<label>Username</label>
<input type="text" name="username">
<br>
<label>UploadImage</label>
<input type="file" name='myfile'>
<br/>
<input type="submit" value="upload">
</form>
</body>
</html>
//php portion
<?php
$user=$_POST['username'];
$image=$_FILES['myfile'];
echo "Hello $user <br/>";
echo "File Name<b>::</b> ".$image['name'];
move_uploaded_file($image['tmp_name'],"photos/".$image['name']);
//here the "photos" folder is in same folder as the upload.php,
//otherwise complete url has to be mentioned
?>
Example 4: upload file to the server php database
<?php
if(isset($_POST['btn-upload']))
{
$file = rand(1000,100000)."-".$_FILES['file']['name'];
$file_loc = $_FILES['file']['tmp_name'];
$file_size = $_FILES['file']['size'];
$file_type = $_FILES['file']['type'];
$folder="uploads/";
move_uploaded_file($file_loc,$folder.$file);
$sql="INSERT INTO tbl_uploads(file,type,size) VALUES('$file','$file_type','$file_size')";
mysql_query($sql);
}
?>
Example 5: php upload from url
<?php
if(isset($_POST['get_image']))
{
$url=$_POST['img_url'];
$data = file_get_contents($url);
$new = 'images/new_image.jpg';
file_put_contents($new, $data);
echo "<img src='images/new_image.jpg'>";
}
?>
Example 6: file upload php
<?php
/*
echo "<pre>";
echo "FILES:<br>";
print_r ($_FILES );
echo "</pre>";
*/
