My scenario, user is posting data and image via android device on to server. I would like the script that handles upload to wait with the response until image is uploaded 100%.
Actually it's not clear to me, since I'm still a beginner, if this script does that already.
When posting item via android, I receive the response pretty fast and image is between 1 and 2MB.
This is the script I'm using now:
<?php
/************************************************
Required PHP Files
************************************************/
require_once("../models/funcs.php");
require_once("../models/db-settings.php");
/************************************************
Functionality
************************************************/
$image_path = "../images/items/";
$image_name = $_FILES['uploaded_file']['name'];
$user_id = $_POST['user_id'];
$query = ...
$result = $my_db->query($query);
$image_path = $image_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $image_path) && !$my_db->error) {
echo 200;
} else{
echo 400;
echo $my_db->error;
echo "There was an error uploading the file, please try again!";
echo "filename: " . basename( $_FILES['uploaded_file']['name']);
echo "target_path: " .$target_path1;
}
?>
This is how PHP has always worked. Your script is run only once upload is finished.
Only recently it's possible to monitor file upload progress.

I already searched lots of stuff, some of them are from stackoverflow. But none of them helped me. What I want to do is reduce the image file size, and after reducing the image will now be uploaded. Here's my current code:
<?php
include 'cloud_functions.php';
// GET THE USER'S ID
$userid = _clean($con, $_POST['userid']);
if(!is_dir("uploads/user/".$userid."/")){
mkdir("uploads/user/".$userid."/", 0755);
}
$temp = explode(".", _clean($con,$_FILES["file"]["name"]));
$targetPath = "uploads/user/".$userid."/";
// RENAME THE IMAGE USING ROUND();
$newFN = round(microtime(true)) . '.' . end($temp);
$targetPath = $targetPath . $newFN;
// GET THE FILE EXTENSION
$type = pathinfo(_clean($con, $_POST['filename']), PATHINFO_EXTENSION);
$all_types = array('jpg', 'png', 'jpeg');
$type = strtolower($type);
if(in_array($type, $all_types)){
if(move_uploaded_file($_FILES['file']['tmp_name'], $targetPath)){
// image uploaded w/o compressing size
echo "1/".$newFN;
}else{
echo $targetPath;
echo "There was an error uploading the file, please try again!";
}
}else{
echo "Please upload a valid image.";
}
?>
In that way I can upload image successfully without compressing its size. Please tell me how to do compress image size before upload. Thanks.
You need to compress image on client side. All the code you posted here is of server side. This code will run after uploading the image to the server.
There are lot of client side libraries for this purpose.
This link will further help. You can choose use any library of your choice.

I think better way - compress image on server after uploading, that to decrease using user memory. It's special important for slow smartphones.
I use this script to upload files via POST from my android app to my server. 95% of the time it works ok, but sometimes the upload folder of my clients is empty. The file is sent definitely, because I get the name and phone numbers (without a file selected the app will not pass any data), but the uploaded file is not written to disk on the server. I am not an expert in php, maybe I have missed something:
My upload php script:
$file_path = "uploads/{$_POST['name']}/";
if (!file_exists("uploads/{$_POST['name']}")) {
mkdir("uploads/{$_POST['name']}", 0777, true);
} else {
echo 'folder already exists!';
}
$newfile = $_POST['name'] . "_" . date('m-d_H-i-s') . '.zip';
$filename = $file_path . $newfile;
if(!file_exists($filename)) {
if(move_uploaded_file($_FILES['zipFile']['tmp_name'], $filename)) {
echo "success";
}
} else {
echo 'file already exists';
}
I need to know code how to rename file before it gets uploaded to my server in php script.Ill post the php code of mine.
I need it because I am uploading an image from phone and I don't want it to be overwritten.
Can I achieve that?
<?php
$file_path = "uploads/";
$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
echo "success";
} else{
echo "fail";
}
?>
For renaming file in Android, you can do :
String file_path = <file path off your existing file you want to rename>
File from = new File(file_path,"from.txt");
File to = new File(file_path,"to.txt");
from.renameTo(to);
This code will work for both file stored in internal or external storage. Just for writing to external storage remember you need to have android.permission.WRITE_EXTERNAL_STORAGE to be added to your Android manifest.
write your code like below.
$filename = $_FILES['upload_file']['name'];
$newname = 'alteredtext'.$filename; // you can also generate random number and concat on start.
$tmp_path = $_FILES['upload_file']['tmp_name'];
if(move_uploaded_file($mp_path, $newname)) {
echo "success";
} else{
echo "fail";
}
You don't need to use the name passed in the $_FILES array when moving the file. You can create any name you want (assuming the path is valid) and pass it as the second argument of move_uploaded_file. If you want a semi-random name, you could generate a random number and then hash it or something to create the filename.
If you want to check first, if the file exists, then rename it to have a numeric suffix, you could do this:
<?php
$base_path = "uploads/";
$file_path = $base_path . basename( $_FILES['uploaded_file']['name']);
if(file_exists($file_path)) {
$ctr = 0;
do { // increment an index to append to the filepath
$ctr++;
$file_path = $base_path . basename( $_FILES['uploaded_file']['name']) . "_$ctr";
} while(file_exists($file_path));
}
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
echo "success";
} else{
echo "fail";
}
?>
The above snippet will keep incrementing until it finds a filename that doesn't exist. Of course, you'd want to add some bounds and error checking, while the above snippet demonstrates the concept, it isn't entirely production ready.
I am a newbie to programming, and this is my first exposure to PHP. I am building a mobile web app where users can upload pictures to the site while at the social event.
I used the PHP script from W3schools (don't hate me please, but it works for my limited knowledge).
Because it is a mobile app I need to add extra functionality but cannot figure out how with the multitude of scripts and my lack of knowledge.
Before the image is uploaded in the script, I would like first do the following.
1) Reduce the dimension to 500px wide and 'auto' the height to retain picture ratio.
2) Compress the file so it is more appropriately filesized for resolution on mobile devices (it will never be printed) and to speed up the upload over cell network.
3) Ensure that the display is correct by way of EXIF data. Right now, iOS, Android and Windows all display portrait and landscape images differently,...I need consistency
Here is my code,...I have remarked where I think it should go but I am not entirely sure.
This code comes up in a pop-up div tag over the page that displays the images.
<?php
$target_dir = "uploads/";
$target_dir = $target_dir . basename( $_FILES["uploadFile"]["name"]);
$target_dir1 = $target_dir . basename( $_FILES["uploadFile"]["tmp_name"]);
$fileTmpLoc = $_FILES["uploadFile"]["tmp_name"];
$uploadOk=1;
// Check if Upload is done without file.
if (!$fileTmpLoc) { // if file not chosen
echo '<script language="javascript">';
echo 'alert("Please browse for a file before clicking the upload button")';
echo '</script>';
echo '<script language="javascript">';
echo 'window.history.back()';
echo '</script>';
}
// Check if file already exists
if (file_exists($target_dir . $_FILES["uploadFile"]["name"])) {
echo "Sorry, file already exists.";
$uploadOk = 0;
}
// Check file size
if ($uploadFile_size > 500000) {
echo "Sorry, your file is too large.";
$uploadOk = 0;
}
//Check no php files
if ($uploadFile_type == "text/php") {
echo "Sorry, no PHP files allowed.";
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk==0) {
echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
//Reduce file to 500px wide
//Compress file
//Rotate file with EXIF data to properly display.
if (move_uploaded_file($_FILES["uploadFile"]["tmp_name"], $target_dir1)) {
echo header( 'Location: gallery.php' ) ;
} else {
echo "Sorry, there was an error uploading your file.";
}
}
?>
Thanks for any help and as mentioned this is my first exposure to PHP.
There is a free utility called SimpleImage.php, available at http://www.white-hat-web-design.co.uk/articles/php-image-resizing.php that will handle resizing and compression and might be a good starting point. There are great examples on their page on how to use it, below is an example of how I use it to resize uploaded images to a certain width:
require_once("SimpleImage.php");
function createThumbnail($cat_code) {
// Check for full size product image
$fname = $this->getImageFilename($cat_code);
if($fname === "") {
echo "<b>createThumbnail: No image file found for " . $cat_code . "!</b><br>";
return false;
}
$thumb = "images/t/" . $cat_code . ".100.jpg";
if($fname !== "") {
$image = new SimpleImage();
$image->load($fname);
$image->resizeToWidth(100);
$image->save($thumb);
}
return true;
}
function process_upload($file, $cat_code, $format, $price=NULL) {
$imageFileExtensions = array('jpg', 'gif', 'png');
$target_path = "uploads/";
$target_path1 = $target_path . basename($file['name']);
$path_info1 = pathinfo($target_path1);
$ext = $path_info1['extension'];
if(move_uploaded_file($file['tmp_name'], $target_path1)) {
if(rename($target_path1, $main_path1)) {
echo "File ". $file['name'] . " verified and uploaded.<br>";
//Create thumbnail if this is an image file
if(in_array($ext, $imageFileExtensions))
$createThumbnail($cat_code);
} else {
echo "<b>ERROR renaming " . $file['name'] . "</b><br>";
}
}
else
echo "<b>move_uploaded_file(" . $file['tmp_name'] . ", $target_path1) failed</b><br>\n";
}
To do a rotate just add another function to the SimpleImage class that uses imagerotate(), for example the following:
function rotate($angle, $bgd_color, $ignore_transparent=0) {
imagerotate($this->image, $angle, $bgd_color, $ignore_transparent);
}
The php.net page for imagerotate has more details on the function parameters.
To work with EXIF data, I use another free utility called PelJpeg.php, available at http://lsolesen.github.io/pel/. There are many examples on how to use this if you google PelJpeg.php. It can get kind of complicated, because as you mention, every platform handles images and meta data a little differently, so you have to do a lot of testing to see what things are handled the same on various platforms, what things are different, and how to bridge across those gaps.
Okay so I am running into issues inserting a file into my database as a blob. I am able to upload the file to a folder on my database but I now want to insert the file into my database as a blob. I know this isnt generally ok to do but I WANT TO DO IT. Anyways I was wondering if anyone had any PHP code to insert a file into a blob table? I've tried using this to no avail maybe I am just not writing the SQL statement right?
<?php
$target = "./";
$target = $target . basename( $_FILES['uploadedfile']['name']);
$file=($_FILES['uploadedfile']['name']);
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
echo "The file ". basename( $_FILES['uploadedfile']['name']).
" has been uploaded";
}else{
echo "There was an error uploading the file, please try again!";
}
mysql_connect("localhost","root","");
mysql_select_db("ivrsupport");
$sql=mysql_query("insert into CUSTOMER (AUDIO_FILE)values
('$file') where PHONE_NUMBER = ('15555215554')");
$r=mysql_query($sql);
if(!$r){
echo "Error in query: ".mysql_error();
}
mysql_close();
?>
I would avoid storing files in the database. That's what FileSystems are for and are much better at doing so. There are millions of posts out there in the blogosphere explaining why not to. Even for a small application I wouldn't do it. It just feels dirty. A blob in the database holds no metadata about the file itself where as a FS can be queried in many ways to gleem information like file size, modification times, permissions etc... My $0.02
You need to read the file into a variable and then insert it.. giving it the filename only wont do.
$fp = fopen($basename, 'r');
$content = fread($fp, filesize($basename));
fclose($fp);
$sql=mysql_query("insert into CUSTOMER (AUDIO_FILE)values
('$content') where PHONE_NUMBER = ('15555215554')");
$file simply contains the name of the file not it's contents.
Try the following:
<?php
$target = "./";
$target = $target . basename( $_FILES['uploadedfile']['name']);
$file=($_FILES['uploadedfile']['name']);
$fileContents = file_get_contents($file);
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
echo "The file ". basename( $_FILES['uploadedfile']['name']).
" has been uploaded";
}else{
echo "There was an error uploading the file, please try again!";
}
mysql_connect("localhost","root","");
mysql_select_db("ivrsupport");
$sql=mysql_query("insert into CUSTOMER (AUDIO_FILE)values
('$fileContents') where PHONE_NUMBER = ('15555215554')");
$r=mysql_query($sql);
if(!$r){
echo "Error in query: ".mysql_error();
}
mysql_close();
