File Upload keeping track
This code is suppose to keep track of how many files have been uploaded increasing at each file. The image name is also suppose to match the # file it is. If the image were the 46th one being uploaded it would be named image46.jpg the name(image) and the extension(.jpg) are gathered else where. but right now i'm getting an error message "Unknown extension!
Fatal error: Cannot redeclare getextension() (previously declared in /hsphere/local/home/crazychr/bluewalrus.net/test/files.php:23) in /hsphere/local/home/crazychr/bluewalrus.net/test/files.php on line 23"
It is going threw the code once but failing. The unknown extenstion is not true its a jpg. This is a mashing of different things I've tried to pick up. I'm new to php as a few of you have noticed i'm sure. Thanks for your time and any ideas you have.
PHP Code:<?php
for($m = 0; $m < count($_FILES['image']); $m++) {
$image = $_FILES['image'][$m];
$counterfile = "number.txt";
$fp = fopen($counterfile,"r");
$hits = fgets($fp,100);
fclose($fp);
$hits++;
$fp = fopen($counterfile,"w");
fputs($fp, $hits);
fclose($fp);
//define a maxim size for the uploaded images in Kb
define ("MAX_SIZE","9000000");
//This function reads the extension of the file. It is used to determine if the file is an image by checking the extension.
function getExtension($str) {
$i = strrpos($str,".");
if (!$i) { return ""; }
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
}
//This variable is used as a flag. The value is initialized with 0 (meaning no error found)
//and it will be changed to 1 if an errro occures.
//If the error occures the file will not be uploaded.
$errors=0;
//checks if the form has been submitted
if(isset($_POST['Submit']))
{
//reads the name of the file the user submitted for uploading
$image=$_FILES['image']['name'];
//if it is not empty
if ($image)
{
//get the original name of the file from the clients machine
$filename = stripslashes($_FILES['image']['name']);
//get the extension of the file in a lower case format
$extension = getExtension($filename);
$extension = strtolower($extension);
//if it is not a known extension, we will suppose it is an error and will not upload the file,
//otherwise we will do more tests
if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif"))
{
//print error message
echo '<h1>Unknown extension!</h1>';
$errors=1;
}
else
{
//get the size of the image in bytes
//$_FILES['image']['tmp_name'] is the temporary filename of the file
//in which the uploaded file was stored on the server
$size=filesize($_FILES['image']['tmp_name']);
//compare the size with the maxim size we defined and print error if bigger
if ($size > MAX_SIZE*1024)
{
echo '<h1>You have exceeded the size limit!</h1>';
$errors=1;
}
//we will give an unique name, for example the time in unix time format
$image_name=$image;
//the new name will be containing the full path where will be stored (images folder)
$newname="/".$image_name . $hits;
//we verify if the image has been uploaded, and print error instead
$copied = copy($_FILES['image']['tmp_name'], $newname);
if (!$copied)
{
echo '<h1>Copy unsuccessfull!</h1>';
$errors=1;
}}}}
//If no errors registred, print the success message
if(isset($_POST['Submit']) && !$errors)
{
echo "<h1>File Uploaded Successfully! Upload Another?</h1>";
}
}
