I have shown you how to create a simple PHP file that will help you to upload a file into a server a few weeks ago. But if you take a look at the post a few weeks ago, you will realise that the output that you are getting after a successful upload isn't very useful at all. Hence, I have made some minor changes to the PHP file so that you will be getting an output in xml format.
<html> <body> <form action="upload_file.php" method="post" enctype="multipart/form-data"> <label for="file">Filename:</label> <input type="file" name="file" id="file" /> <br /> <input type="submit" name="submit" value="Submit" /> </form> </body> </html>And a simple PHP file that will handle all the uploading...
<?php
//Header for xml file
header ("Content-Type:text/xml");
//Maximum filesize that can be uploaded through this file
$filesize = 1000;
//The folder that all the uploads will be place in
$folderName = "uploads/";
$output = "";
// detect slash/backslash nomenclature dirname
$path = dirname( __FILE__ );
$slash = '/'; strpos( $path, $slash ) ? '' : $slash = '\\';
define( 'BASE_DIR', $path . "/" );
$dirPath = BASE_DIR . $folderName; // folder path
//If the filesize of the file is smaller than the maximum filesize
if ($_FILES["file"]["size"] < $filesize)
{
//If there is an error
if ($_FILES["file"]["error"] > 0)
{
//Create a xml node with the name of 'error' and write the type of error into the node
$output = createDataXMLNode("error",$_FILES["file"]["error"]);
}else{
//Display more info about the uploaded file
//Create a xml node with the name of 'name' and write the file name into the node
$output = createDataXMLNode("name",$_FILES["file"]["name"]);
//Create a xml node with the name of 'type' and write the file type into the node
$output .= createDataXMLNode("type",$_FILES["file"]["type"]);
//Create a xml node with the name of 'size' and write the file size into the node
$output .= createDataXMLNode("size",($_FILES["file"]["size"] / 1024) . " Kb");
//We don't need the info of the temp file.
//echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";
//If the folder hasn't been created yet, create it now
if(!is_dir($dirPath))
mkdir($dirPath,0777);
//If the file already exist
if (file_exists($dirPath . $_FILES["file"]["name"]))
{
//Create a xml node with the name of 'error' and indicate that a similar file has exists into the node
$output = createDataXMLNode("error",$_FILES["file"]["name"]." file exist");
}else{
//Copy the uploaded file into the specified folder
move_uploaded_file($_FILES["file"]["tmp_name"],
$dirPath . $_FILES["file"]["name"]);
//Create a xml node with the name of 'path' and write the file path into the node
$output .= createDataXMLNode("path", removeFileName(). $folderName . $_FILES["file"]["name"]);
}
}
}else{
//Create a xml node with the name of 'error' and write 'Invalid file' into the node
$output = createDataXMLNode("error","Invalid file");
}
//Create a xml node with the name of 'file' and write all the values of $output into the node
echo createNormalXMLNode("file",$output);
//Function for creating a Generic XML node
function createNormalXMLNode($name,$value){
return "<" . $name . ">" . $value . "</" . $name . ">";
}
//Function for creating a normal XML node that contains some values that might have illegal characters
function createDataXMLNode($name,$value){
return "<" . $name . "><![CDATA[" . $value . "]]></" . $name . ">";
}
//Function to get the url of the current page
function curPageURL() {
$pageURL = 'http';
if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
$pageURL .= "://";
if ($_SERVER["SERVER_PORT"] != "80") {
$pageURL .= $_SERVER["HTTP_HOST"].":";
$pageURL .= $_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
} else {
$pageURL .= $_SERVER["HTTP_HOST"].$_SERVER["REQUEST_URI"];
}
return $pageURL;
}
//Function to get the url of the current page and remove the filename of this page
function removeFileName(){
$pageURL = curPageURL();
$pieces = explode("/", $pageURL);
$piecesLength = count($pieces);
$pageURL = "";
for ( $counter = 0; $counter < ($piecesLength - 1); $counter ++) {
$pageURL = $pageURL. $pieces[$counter]."/";
}
return $pageURL;
}
?>Note: after you have uploaded a file, you will realise that the output looks kinda strange. This is because I'm using a free web hosting services and it is adding some extra lines of codes to my output. But if you look at my source codes, you can easily find a neatly formatted xml in the output.
