Files to Functions

[Guest]

Is there a way to upload a file in a form and send $_FILES['file']['name'] to a function for editing? Can someone please help. Thank You

To upload the file use this one

[code]
<?php
<form enctype="multipart/form-data" action="_URL_" method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="30000">
Send this file: <input name="userfile" type="file">
<input type="submit" value="Send File">
</form>
?>

[/code]

Once you upload the file you can pass the file name to any function ($_FILES['file']['usefile'])

I tried to pass the file to the function and the function has no data if i upload an image name image1 and type file
i send it to the function by $_FILES['image1'] and there is also no data inside the function lets say i wanted to get the size and the name in the function how would i send the file and how would i recive the file would i use $image or what on the function definition?

See!

You can't checka filename like $_FILES['image1']

you must use $_FILES['file']['name'].this will give the  flename just upload!

If you can post your code here it will be useful to help you!

I do this
[code]function getFileExtension($str) {
    $i = strrpos($str,".");
    if (!$i) { return ""; }
    $l = strlen($str) - $i;
    $ext = substr($str,$i+1,$l);
    return $ext;
}

$ext = getFileExtension($_FILES['image1']['name']);
[/code]

$ext is blank i cant figue out why the functions are in different files included of course

Best way imo:

[code]<?php

function getFileExtension($str)
{
if(strpos($str,".") === FALSE) return "":
$parts = explode(".",$str);
return $parts[count($parts) - 1];
}

?>[/code]

Orio.

[code]
getimagesize($_FILES['image1']['tmp_name'])

Warning: getimagesize(/tmp/phpSULyxK) [function.getimagesize]: failed to open stream: No such file or directory in imagefunctions.php on line 81

Warning: copy(/tmp/phpSULyxK) [function.copy]: failed to open stream: No such file or directory in
[/code]

I dont get whats going on if its not in functions all this works correctly. Is there somthing im missing am i doing it wrong?

Are you sure that image1 file is there on the location from where you are trying to get the size of it.
