How to upload & Save Files with Desired name
You can grab the demo source code from here: http://abhinavsingh.com/blog/2008/05/gmail-type-attachment-how-to-make-one/
It is ready to use, or you can modify to suit your application needs. Hope it helps :)
You can try this,
$info = pathinfo($_FILES['userFile']['name']);
$ext = $info['extension']; // get the extension of the file
$newname = "newname.".$ext;
$target = 'images/'.$newname;
move_uploaded_file( $_FILES['userFile']['tmp_name'], $target);
This would work very well -- You can use HTML5 to allow only image files to be uploaded. This is the code for uploader.htm --
<html>
<head>
<script>
function validateForm(){
var image = document.getElementById("image").value;
var name = document.getElementById("name").value;
if (image =='')
{
return false;
}
if(name =='')
{
return false;
}
else
{
return true;
}
return false;
}
</script>
</head>
<body>
<form method="post" action="upload.php" enctype="multipart/form-data">
<input type="text" name="ext" size="30"/>
<input type="text" name="name" id="name" size="30"/>
<input type="file" accept="image/*" name="image" id="image" />
<input type="submit" value='Save' onclick="return validateForm()"/>
</form>
</body>
</html>
Now the code for upload.php --
<?php
$name = $_POST['name'];
$ext = $_POST['ext'];
if (isset($_FILES['image']['name']))
{
$saveto = "$name.$ext";
move_uploaded_file($_FILES['image']['tmp_name'], $saveto);
$typeok = TRUE;
switch($_FILES['image']['type'])
{
case "image/gif": $src = imagecreatefromgif($saveto); break;
case "image/jpeg": // Both regular and progressive jpegs
case "image/pjpeg": $src = imagecreatefromjpeg($saveto); break;
case "image/png": $src = imagecreatefrompng($saveto); break;
default: $typeok = FALSE; break;
}
if ($typeok)
{
list($w, $h) = getimagesize($saveto);
$max = 100;
$tw = $w;
$th = $h;
if ($w > $h && $max < $w)
{
$th = $max / $w * $h;
$tw = $max;
}
elseif ($h > $w && $max < $h)
{
$tw = $max / $h * $w;
$th = $max;
}
elseif ($max < $w)
{
$tw = $th = $max;
}
$tmp = imagecreatetruecolor($tw, $th);
imagecopyresampled($tmp, $src, 0, 0, 0, 0, $tw, $th, $w, $h);
imageconvolution($tmp, array( // Sharpen image
array(−1, −1, −1),
array(−1, 16, −1),
array(−1, −1, −1)
), 8, 0);
imagejpeg($tmp, $saveto);
imagedestroy($tmp);
imagedestroy($src);
}
}
?>
