Page Refresh Image Upload Help

php, image, ajax, xmlhttprequest

[confused noob]

Hello all!

what is wrong with my code?

<?php>
echo ($HTTP_POST_FILES['thefile']['name']);
$file_realname = trim($HTTP_POST_FILES['thefile']['name']);
$uploaddir = "/images/";

if (move_uploaded_file($HTTP_POST_FILES['thefile']['tmp_name'], $uploaddir . $file_realname)) {
} else {
print "<strong>$file_realname</strong> did not upload!";
}
?>

The code above is called from a ASP page but I seem to lose the file in translation. What am I doing wrong. Why won't the code upload the image from an ASP form?

Also, is it possible to follow this path: ASP(FORM) -> JS(XMLHTTPREQUEST) -> PHP(UPLOAD FUNCTION)

I am attempting to refresh part of the page.

Thanks for you help.

Welcome to WebmasterWorld!

Try the following, first, and see what it gives you. Put this at the top of this script:

echo '<pre>'; print_r($_FILES); echo '</pre>';
exit;

This is what it gave me:

Array
(
[thefile] => Array
(
[name] => SN151380.JPG
[type] =>
[tmp_name] =>
[error] => 2
[size] => 0
)

)

You are getting an error 2 which means "The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form."

You must upload a smaller file or increase the max_file_size in the form.

Ok, as of right now, this is what I have set for the max_file_size = 150000. The file I am uploading is only 940kb.

<input type=hidden name=MAX_FILE_SIZE value=150000>

I am changing the attributes and testing...brb

This is the js function within the asp page that calls the php page.

function updateImg(action, uID, param1)
{
xmlHttp=GetXmlHttpObject()
if (xmlHttp==null)
{
alert ("Browser does not support HTTP Request")
return
}
var filename = document.form1.whatsit.value;//Image Name

alert (filename);
var url="test.php"
url=url+"?action="+action
url=url+"&username="+uID
url=url+"&param1="+param1
//url=url+"&param2="+param2
url=url+"&sid="+Math.random()
xmlHttp.onreadystatechange=stateChanged
xmlHttp.open("GET",url,true)
xmlHttp.send(null)

}

when I run this script, with the code you gave me, it get the following:

Array
(
)

Is this not possible? To go from Embedded JS in ASP to PHP.

[eelixduppy]

It is certainly possible to achieve this asynchronous upload. You will probably have better help in the Javascript/AJAX [webmasterworld.com] forum, though, as the javascript may get a little more complicated.

[confused noob]

I will try that...thanks for you help...I am 85% there..
