I have a code that works when uploading an image to a webserver folder. However, I need to uplaod many images. How can I edit this code for say 6 images?
<?php
//define a maxim size for the uploaded images in Kb
define ("MAX_SIZE","100");
//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 '<h2>Unknown extension!</h2>';
$errors=1;
}
else
{
//get the size of the image in bytes
//$_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*91024)
{
echo '<h2>You have exceeded the size limit!</h2>';
$errors=1;
}
//we will give an unique name, for example the time in unix time format
$image_name=time().'.'.$extension;
//the new name will be containing the full path where will be stored (images folder)
$newname="images/".$image_name;
//we verify if the image has been uploaded, and print error instead
$copied = copy($_FILES['image']['tmp_name'], $newname);
if (!$copied)
{
echo '<h2>Copy unsuccessfull!</h2>';
$errors=1;
}}}}
//If no errors registred, print the success message
if(isset($_POST['Submit']) && !$errors)
{
$sellerid = $_SESSION['Seller_id'];
$con = mysql_connect("localhost","XXX","XXX");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("XXXXXX", $con);
$sql="UPDATE property
SET Prop_image_address='$newname'
WHERE Prop_owner_id='$sellerid'";
if (!mysql_query($sql,$con))
{
die('Error: ' . mysql_error());
}
echo "<h2>Your Photo Uploaded Successfully!</h2>";
mysql_close($con);
}
?>
