Hello there.
I have a problem i don´t seem to understand why it wont work out the way i intend it to.
The only thing i can think of is that the headers or the upload data don´t get transfered correctly.
I will show you 3 files that involves the problem:
First my javascript that uses the Prototype Framwork.
Code:
function AjaxUpload(MyUrl, MyDiv, TargetDiv)
{
var TargetDiv;
var MyDiv;
var MyUrl;
new Ajax.Request(MyUrl, {
method: 'post',
contentType: 'multipart/form-data',
encoding: 'UTF-8',
parameters: $(TargetDiv).serialize(true),
onCreate: function(transport)
{
var MyStatusText = $('MyStatusDiv');
MyStatusText.addClassName('standardBox');
new Ajax.Updater(MyStatusText, 'ajax_loader.php');
},
onSuccess: function(transport)
{
// var MyResponseText = $(MyDiv);
// dölj div före utfällning och lägg på class
// $('ajax_container').hide();
$(MyDiv).addClassName('standardBox');
// skicka in data i div
$(MyDiv).update(transport.responseText);
// fäll ut div, pulsera och visa data
// Effect.toggle('ajax_container', 'blind');
$(MyDiv).show();
Effect.Pulsate(MyDiv);
},
onComplete: function(transport)
{
var MyStatusText = $('MyStatusDiv');
MyStatusText.update('');
MyStatusText.removeClassName('standardBox');
}
});
}
And the upload form:
PHP Code:
<form id="ajaxUploadForm" action="#" method="post">
<!-- MAX_FILE_SIZE must precede the file input field -->
<input type="hidden" name="MAX_FILE_SIZE" value="<?PHP echo(1024*1024*100); ?>" />
Fil att ladda upp:<br />
<input name="userfile" type="file" size="30" maxlength="" />
<br /><br />
<input type="hidden" name="token" value="test_<?PHP echo(md5(microtime())); ?>" />
<input type="submit" name="SUBMIT" value="Ladda upp" onclick="AjaxUpload('ajax_upload.php', 'ajax_container', 'ajaxUploadForm'); return false"/>
</form>
And the php code that should provide the logic for upload.
This file is called by the JavaScript function mentioned.
PHP Code:
<?PHP
/* Debug styff */
print_r($_FILES);
echo('<br /><br />');
echo('Debug token: ' . $_POST['token']);
echo('<br /><br />');
/* Debug styff */
$error = $_FILES["userfile"]["error"];
// where to upload
$uploaddir = '/home/virtual/myhost/public_html/uploads/';
// make a random file prefix
$file_prefix = 'id_' . substr(md5(microtime() . mt_rand(1, 1000000)), 0, 16) . '_';
$uploadfile = $uploaddir . basename($file_prefix . $_FILES['userfile']['name']);
$upload_file_name = basename($file_prefix . $_FILES['userfile']['name']);
// Do the upload
if(move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile))
{
/* Is the Mime type valid ? */
$file_content_type = $_FILES['userfile']['type'];
$permited_mimes[] = 'image/jpeg';
$permited_mimes[] = 'image/gif';
$permited_mimes[] = 'image/png';
if(in_array($file_content_type, $permited_mimes)){
} else {
unlink('uploads/' . $upload_file_name);
$upload_file_name = '';
echo('filetype type not valid!');
exit;
}
} else {
echo('An Upload error accured!');
exit;
}
echo('File:' . $upload_file_name . ' Has been uploaded.<br />');
echo('Error code: ' . $error);
?>
I guess the problem is in the $_FILES array not reaching the upload logic code.
Do you gurus have any tips ? :$
If there is odd words somewhere, it´s because im swedish ;)
