Initially files are updated into a temp directory which you can configure in your "/etc/php.ini", then it got relocated to a target destination by php script.
Below is an example of php script (http://www.tutorialspoint.com/php/php_file_uploading.htm)that allows "jpeg, jpg, png" file upload.
<?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'])));
$expensions= array("jpeg","jpg","png");
if(in_array($file_ext,$expensions)=== 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);
}
}
?>
<html>
<body>
<form action="" method="POST" enctype="multipart/form-data">
<input type="file" name="image" />
<input type="submit"/>
<ul>
<li>Sent file: <?php echo $_FILES['image']['name']; ?>
<li>File size: <?php echo $_FILES['image']['size']; ?>
<li>File type: <?php echo $_FILES['image']['type'] ?>
</ul>
</form>
</body>
</html>
For a successfuly upload, it produces the following results:
Success Sent file: games.jpg File size: 33562 File type: image/jpeg
You need to create a "images" directory where upload_img.php resides. In my case is "/var/www/html"
# ls /var/www/html/ images index.htm upload_img.php
Assume your HTTP server is 192.169.0.2, you can use the following curl command to test:
# curl --form image=@test1.jpg http://192.168.0.2/upload_img.php Success<html> <body> <form action="" method="POST" enctype="multipart/form-data"> <input type="file" name="image" /> <input type="submit"/> <ul> <li>Sent file: test1.jpg <li>File size: 22 <li>File type: image/jpeg </ul> </form> </body> </html> # ll /var/www/html/images/ total 22 -rw-r--r--. 1 apache apache 22 Oct 29 15:21 test1.jpg
You can use "--form username=" etc for other form parameters.
