I tried what you were saying. I might not be doing it right, but its just overwritting the ones that are already upload.
PHP Code:
<?php
$upload_dir = "images/";
$size_bytes = 524880; // = 5 megabytes(MB)
$limit_file_type = "yes";
$allowed_file_type = array('image/gif',
'image/pjpeg',
'image/jpeg',
'image/png',
'image/jpg');
//check if the directory exist or not.
if (!is_dir("$upload_dir")) {
die ("The directory <b>($upload_dir)</b> doesn't exist");
}
//check if the directory is writable.
if (!is_writeable("$upload_dir")){
die ("The directory <b>($upload_dir)</b> is NOT writable, Please Chmod (777)");
}
//Check first if a file has been selected
//is_uploaded_file('filename') returns true if
//a file was uploaded via HTTP POST. Returns false otherwise.
if (is_uploaded_file($_FILES['filetoupload']['tmp_name']))
{//begin of is_uploaded_file
//Get the Size of the File
$size = $_FILES['filetoupload']['size'];
//Make sure that $size is less than 1MB (1000000 bytes)
if ($size > $size_bytes)
{
echo "File Too Large. File must be <b>$size_bytes</b> bytes.";
exit();
}
//check file type
if (($limit_file_type == "yes") && (!in_array($_FILES['filetoupload']['type'],$allowed_file_type)))
{
echo"wrong file type";
exit();
}
// $filename will hold the value of the file name submetted from the form.
$filename = $_FILES['filetoupload']['name'];
// Check if file is Already EXISTS.
define('DIRECTORY', './images/');
function getImageName($szImage)
{
$iIndex = 2;
if(!file_exists(DIRECTORY . $szImage))
{
return $szImage;
}
$aParts = explode('.', $szImage);
if(count($aParts) <= 1)
{
return $szImage;
}
$szExt = end($aParts);
$iCount = count($aParts);
$aParts[$iCount - 1] = $iIndex;
$aParts[$iCount] = $szExt;
do { $aParts[count($aParts) - 2] = $iIndex++; }
while(file_exists(DIRECTORY . implode('.', $aParts)));
return implode('.', $aParts);
}
//Move the File to the Directory of your choice
//move_uploaded_file('filename','destination') Moves afile to a new location.
if (move_uploaded_file($_FILES['filetoupload']['tmp_name'],$upload_dir.$filename)) {
//tell the user that the file has been uploaded and make him alink too;).
echo "File (<a href=$upload_dir$filename>$filename</a>) uploaded!";
exit();
}
else
{
//Print error
echo "There was a problem moving your file";
exit();
}
}//end of is_uploaded_file
?>
