- How can I upload files asynchronously? 33 answers
I am using pre made code (http://www.jqueryrain.com/?ckQjAttu) to make a photo uploader and cropper. Obviously there code all works fine but all I want to add is: when the user selects a photo the form is automatically submitted. heres the current java script I am using to attempt this.
<form action="my_upload.php" enctype="multipart/form-data" method="post"
class="upload" name="upload">
<input name="image" size="30" type="file" id="file">
<input name="upload" type="submit" value="Edit Photo" id="upload">
</form>
</div>
<script type="text/javascript">
$('form.upload').on('change', function() {
document.upload.submit();
});
</script>
This does submit the form and takes the user to 'my_upload.php' and normally when the photo is uploaded it appears on the page. However when it is uploaded like this nothing appears at all!!
here is there php script ('my_upload.php') which have slightly edited for storing the photo and design of the page:
<?php
require 'core.php';
require 'connect.php';
