I am trying to upload a captured image from android device to remote server via PHP - ftp_put() function. The Android code is working, I just do not get it work from php side.
Explanation: On Android/Java side I encode bitmap to string and decode it in PHP ($binary). I want to upload this bitmap to remote server. Please see my PHP code:
<?php
if ($tag == 'upload') {
//Get data from client
$uid = $_POST['uid'];
$base = $_POST["image"];
$date = date('Y-m-d-H-m-s');
if (isset($base)) {
//function creates random numbers and stores in $suffix
$suffix = $db->createRandomID();
//Prepare image name
$image_name_ = "img_".$suffix."".$uid."_".date("Y-m-d-H-m-s").".jpg";
// base64 encoded utf-8 string
$binary = base64_decode($base);
// binary, utf-8 bytes
header("Content-Type: bitmap; charset=utf-8");
//Basic ftp information
$ftp_server = "xxx.xxx.com";
$ftp_user_name = "xxxxx";
$ftp_user_pass = "xxxxx";
$file = $binary;
$remote_file = "/public_html/uploads/".$image_name_;
// set up basic connection
$conn_id = ftp_connect($ftp_server);
// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
// upload a file
if (ftp_put($conn_id, $remote_file, $file, FTP_ASCII)) {
$response["success"] = "Upload";
echo json_encode($response);
} else {
$response["error"] = "failed";
}
// close the connection
ftp_close($conn_id);
}
?>
LogCat says: No such file or directory ... Line if (ftp_put($conn_id, $remote_file, $file, FTP_ASCII))

i need a list of all the files on an FTP server. I can get a list of files using php , but no idea how to get the file size. How do I get the file sizes? Thanks.
You can call
ftp_size
As in
int ftp_size ( resource $ftp_stream , string $remote_file )
To get the size of files over FTP.
For example:
$file = 'somefile.txt';
// set up basic connection
$conn_id = ftp_connect($ftp_server);
// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
// get the size of $file
$res = ftp_size($conn_id, $file);
if ($res != -1) {
echo "size of $file is $res bytes";
} else {
echo "couldn't get the size";
}
// close the connection
ftp_close($conn_id);
However only some FTP servers support this.

i have tried to upload the image into the server but i could not have the permission to access the folder so i have used the FTP connection. Through the android app i have encode the image and sent it to the server. In the server side, i just decode it and tried to upload it. But i could not able to upload it. Can you please help me on this.
<?php
// Get image string posted from Android App
$base=$_REQUEST['image'];
// Get file name posted from Android App
$filename = $_REQUEST['filename'];
// Decode Image
$binary=base64_decode($base);
header('Content-Type: bitmap; charset=utf-8');
$ftp_server = "";
$ftp_user_name = "";
$ftp_user_pass = "";
$destination_file = "/upload/images/".time().jpg";
$conn_id = ftp_connect($ftp_server);
ftp_pasv($conn_id, true);
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
if ((!$conn_id) || (!$login_result)) {
echo "FTP connection has failed!";
echo "Attempted to connect to $ftp_server for user $ftp_user_name";
exit;
} else {
echo "Connected to $ftp_server, for user $ftp_user_name,$conn_id";
}
$upload = ftp_put($conn_id, $destination_file, $binary, FTP_BINARY);
if (!$upload) {
echo "FTP upload has failed! $upload";
} else {
echo "Uploaded $source_file to $ftp_server as $destination_file";
}
ftp_close($conn_id);
?>
The third param of the function ftp_put expects a filename. You are passing the image binary as a string.
Change tis line:
$upload = ftp_put($conn_id, $destination_file, $binary, FTP_BINARY);
To:
$fileName = uniqid().'.jpg';
$filePath = '/tmp/'.$uniqid;
file_put_contents($filePath, $binary);
$upload = ftp_put($conn_id, $destination_file, $filePath, FTP_BINARY);
please add ftp_pasv($conn_id, true); after successful login. Then only this will work.
I need to use php to upload to an ftp server 4 files. I have the following example code, that I am working from. How could this code be changed to upload multiple files that were already on the server (not uploaded at the time of the ftp transfer).
Lets say I have 4 files in a subfolder relative to the php file that does the upload, lets call the subfolder “/fileshere/” with the following 4 files in it:
file1.zip
file2.zip
file3.zip
file4.zip
I need the script to upload each of the files, then give a done message.
Below is the starting code I am using and trying to adapt. Any help would be much appreciated:
$ftp_server = "ftp.yourserver.com";
$ftp_user_name = "ftpuser";
$ftp_user_pass = "ftppassword";
$remote_dir = "/target/folder/on/ftp/server";
// set up basic connection
$conn_id = ftp_connect($ftp_server);
// login with username and password
$login_result = #ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
//default values
$file_url = "";
if($login_result) {
//set passive mode enabled
ftp_pasv($conn_id, true);
//check if directory exists and if not then create it
if(!#ftp_chdir($conn_id, $remote_dir)) {
//create diectory
ftp_mkdir($conn_id, $remote_dir);
//change directory
ftp_chdir($conn_id, $remote_dir);
}
$file = $_FILES["file"]["tmp_name"];
$remote_file = $_FILES["file"]["name"];
$ret = ftp_nb_put($conn_id, $remote_file, $file, FTP_BINARY, FTP_AUTORESUME);
while(FTP_MOREDATA == $ret) {
$ret = ftp_nb_continue($conn_id);
}
if($ret == FTP_FINISHED) {
echo "File '" . $remote_file . "' uploaded successfully.";
} else {
echo "Failed uploading file '" . $remote_file . "'.";
}
} else {
echo "Cannot connect to FTP server at " . $ftp_server;
}
Try this code
<?php
// connect and login data
$web = 'www.website.com';
$user = 'admin';
$pass = 'password';
// file location
$server_file = '/public_html/example.txt';
$local_file = 'example.txt';
//connect
$conn_id = ftp_connect($web);
$login_result = ftp_login($conn_id,$user,$pass);
//uploading
if (ftp_put($conn_id, $server_file, $local_file, FTP_BINARY))
{echo "Success";}
else {echo "Failed";}
?>
if you want to upload multiple files just put your files names into array then put whole code into for loop .
$fp = 'test.png';
$server_file = "dir/testing.png";
//-- Connection Settings
$ftp_server = 'ftp.net';; // Address of FTP server.
$ftp_user_name ='user'; // Username
$ftp_user_pass = 'password'; // Password
// set up basic connection
$conn_id = ftp_connect($ftp_server,21);
// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
$mode = ftp_pasv($conn_id, TRUE);
$download=ftp_get($conn_id, $fp, $server_file, FTP_BINARY);
// try to download $server_file and save to $local_file
if ( $download) {
echo "Successfully $fp\n";
} else {
echo "There was a problem\n";
}
ftp_close($conn_id);
When I run this it says it is successfully, but will not write or download the file.
If I echo file_get_contents($fp); then it will display the image deconstructed into text [in the Web browser]
In need to download images and video...
Try adding
header('Content-Type: image/png');
How can I save an image over FTP? Here's my code:
$conn_id = ftp_connect('***');
$login_result = ftp_login($conn_id, '***','***');
if( $login_result) echo 'connected';
$save = "FTP://temp/". $FileName;
imagepng($this->Picture, $save);
/*if (ftp_put($conn_id,$save,$save, FTP_ASCII))
echo "successfully uploaded \n";
else
echo "There was a problem while uploading \n";
*/
You could do:
ob_start();
imagepng($this->Picture);
$image = ob_get_clean();
$stream = stream_context_create(array('ftp' => array('overwrite' => true)));
file_put_contents("ftp://user:pass#host/folder/".$FileName, $image, 0, $stream);
Hope this helps you
