Upload image con rename da input

[mario19xx]

Ciao ho questo script:

<?php
function getExtension($str)
{
 $i = strrpos($str,".");
 if (!$i) { return ""; }
 
 $l = strlen($str) - $i;
 $ext = substr($str,$i+1,$l);
 return $ext;
}
    if (isset($_POST['lol']))
    {
$image =$_FILES["imagefile"]["name"];
$tempext = getExtension($image);
$name = ciao;
$extfile= $name.".".$tempext;
$uploadedfile = $_FILES['imagefile']['tmp_name'];
 
if ($extfile)
{
$filename = stripslashes($extfile);
$extension = getExtension($filename);
$extension = strtolower($extension);
if (($extension != "jpg") && ($extension != "jpeg")
&& ($extension != "png") && ($extension != "gif"))
{
$errors=1;
}
else
{
$size=filesize($_FILES['imagefile']['tmp_name']);
 
if($extension=="jpg" || $extension=="jpeg" )
{
$uploadedfile = $_FILES['imagefile']['tmp_name'];
$src = imagecreatefromjpeg($uploadedfile);
}
else if($extension=="png")
{
$uploadedfile = $_FILES['imagefile']['tmp_name'];
$src = imagecreatefrompng($uploadedfile);
}
else
{
$src = imagecreatefromgif($uploadedfile);
}
 
list($width,$height)=getimagesize($uploadedfile);
 
$newwidth=150;
$newheight=($height/$width)*$newwidth;
$tmp=imagecreatetruecolor($newwidth,$newheight);
imagecopyresampled($tmp,$src,0,0,0,0, $newwidth, $newheight, $width, $height);
 
$filename = "images/". $extfile;
 
$etest1=imagejpeg($tmp,$filename,100);
 
imagedestroy($src);
imagedestroy($tmp);
}
}
}
?>

Form

<form method="POST" enctype="multipart/form-data">
<input type="text" name="nome">


<input type="file" name="imagefile">


<input name="lol" type="submit" value="Sumbit">
</form> 

Allora voglio fare in modo che "input lol" il valore a "$name = ciao;" con $_POST non va.

Grazie!
