There are multiple resources online which deal with this issue, a quick search comes up with exactly what you are looking for, please research and dont ask other people to do all the work.

Post an example of what you have if it isnt working and we can assist you.
AJAX is not a programming language, scripting language or any other sort of language.
It is acheived by using JavaScript http functions.
So, AJAX = JavaScript.

See if this helps. To use this script, you need to create a folder named uploads where the uploaded files would be stored.
PHP Syntax (Toggle Plain Text) 
  1. <?php
  2. $maxsize=28480; // Set the maximum upload size in bytes
  3. if (!$_POST['submit']) {
  4.     //print_r($_FILES);
  5. 	$error=" ";
  6. 	// This will cause the rest of the process to be skipped
  7. 	//and the upload form displays
  8. }
  9. if (!is_uploaded_file($_FILES['upload_file']['tmp_name']) AND
  10. !isset($error)) {
  11.     $error = "<b>You must upload a file!</b><br /><br />";
  12. 	unlink($_FILES['upload_file']['tmp_name']);
  13. }
  14. if ($_FILES['upload_file']['size'] > $maxsize AND !isset($error)) {
  15.     $error = "<b>Error, file must be less than $maxsize bytes.</b><br /><br />";
  16. 	unlink($_FILES['upload_file']['tmp_name']);
  17. }
  18. if($_FILES['upload_file']['type'] != "image/gif" AND
  19. $_FILES['upload_file']['type'] != "image/pjpeg" AND
  20. $_FILES['upload_file']['type'] !="image/jpeg" AND !isset($error)) {
  21.     $error = "<b>You may only upload .gif or .jpeg files.<b><br /><br />";
  22. 	unlink($_FILES['upload_file']['tmp_name']);
  23. }
  24. if (!isset($error)) {
  25.     move_uploaded_file($_FILES['upload_file']['tmp_name'],
  26. 	                   "uploads/".$_FILES['upload_file']['name']);
  27. 	print "Thank you for your upload.";
  28. 	exit;
  29. }
  30. else
  31. {
  32.     echo ("$error");
  33. }
  34. ?>
  35.  
  36. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
  37. <html xmlns="http://www.w3.org/1999/xhtml">
  38. <head>
  39. <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
  40. <title>PHP File Upload Script</title>
  41. </head>
  42.  
  43. <body>
  44. <form action="<?php echo(htmlspecialchars($_SERVER['PHP_SELF']))?>" method="post"
  45. enctype="multipart/form-data">
  46.     Choose a file to upload:<br />
  47. 	<input type="file" name="upload_file" size="50" />
  48. 	<br />
  49. 	<input type="submit" name="submit" value="Submit" />
  50. 	<input type="reset" name="Reset" value="Reset" />
  51. </form>
  52. </body>
  53. </html>

This bit of code moves the uploaded file from a temporary directory into the uploads directory:
PHP Syntax (Toggle Plain Text) 
  1. move_uploaded_file($_FILES['upload_file']['tmp_name'],
  2. 	                   "uploads/".$_FILES['upload_file']['name']);

The MIME types included here are: .gif, .pjpeg and .jpeg but you may like to add more file formats.
This first line of the code defines the maximum file size:
PHP Syntax (Toggle Plain Text) 
  1. $maxsize=28480; // Set the maximum upload size in bytes
You can edit the size to suit your needs.

Sorry to rain on your parade, but you should never go by $_FILES['upload_file']['type'] as a security check since this is just a line in the header and can easily be reproduced manually. The browser doesn't even have to provide this info to php so sometimes you won't even be given this info. I could very easily send a php file with the header of "image/gif" or if this is a mail script I could send a virus or what ever I wanted to. You should always parse $_FILES['upload_file']['name'] and check the extension that way. This is how I would go about verifying the extension of the filename.
php Syntax (Toggle Plain Text) 
  1. <?php
  2. function returnFileName($file)
  3. {
  4. 	$dot = strrpos($file, '.');
  5. 	if($dot === false)//file has no dot
  6. 	{
  7. 		return false;
  8. 	}
  9.  
  10. 	$fileinfo = array();
  11. 	$fileinfo['base'] = substr($file, 0, $dot);
  12. 	$fileinfo['ext'] = strtolower(substr($file, $dot + 1));
  13. 	return $fileinfo;
  14. } 
  15.  
  16. $allowedext = array("jpg", "gif");
  17. $filearray = returnFileName(basename($_FILES['upload_file']['name']));
  18.  
  19. if($filearray == false || !isset($filearray['ext']) || !in_array($filearray['ext'], $allowedext))
  20. {
  21. 	$error .= "invalid file type";
  22. }
  23. ?>

And the opportunity to bring into the open and alert countless others of a security misconception that apparently often goes unnoticed.
