I am trying to upload an image to my server but can't seem to get it to work. I am using android and volley to get the image and then sending it to the php to upload.
I am using wamp as well.
Says "successfully uploaded" but is not in the directory?
PHP CODE:
<?php
if($_SERVER['REQUEST_METHOD']=='POST'){
$image = $_POST['image'];
$username = $_POST['username'];
require_once('dbConnect.php');
$sql ="SELECT profilepictureID FROM tbl_userprofilepictures ORDER BY profilepictureID ASC";
$res = mysqli_query($con,$sql);
$profilepictureID = 0;
while($row = mysqli_fetch_array($res)){
$profilepictureID = $row['profilepictureID'];
}
$path = "000001/$profilepictureID.JPG";
$actualpath = "http://*wamp server ip*/Users/Images/$path";
$sql = "INSERT INTO tbl_userprofilepictures(username,profilepicturepath) VALUES ('$username','$actualpath')";
if(mysqli_query($con,$sql)){
file_put_contents($path,base64_decode($image));
echo "Successfully Uploaded";
}
mysqli_close($con);
} else{
echo "Error";
}
?>

any help from your side will be appreciated
For uploading an image, you need to use
$_FILES['image']
instead of
$_POST['image']
Actually My problem is when I am registering user profile on localhost is working fine and image is storing in folder but after published is not storing image in folder.
my php code
$target_dir = "../upload/";
$target_file = $target_dir . basename($_FILES["photo"]["name"]);
$uploadOk = 1;
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
} else {
move_uploaded_file($_FILES["photo"]["tmp_name"], $target_file);
}
$name = $_POST["name"];
$email = $_POST["email"];
$sql = "SELECT email FROM register where email='$email'";
$qur = $connection->query($sql);
if(mysqli_num_rows($qur)==0)
{
$password = md5($_POST["password"]);
$birth = $_POST["birth"];
$sql = "INSERT INTO register(name, email,password,photo,birth)
VALUES ('$name','$email','$password','$target_file','$birth')";
$success = $connection->query($sql);
if (!$success) {
die("Couldn't enter data: ".$connection->error);
}else{
echo "Thank You For registration";
}
}else{echo "Email-id already exist";
}
most of the time server need dont allow to upload data.
you need to give permission to your upload folder and it will work
You can check your error: $_FILES['photo']['error']
You can get more detail from here :- http://php.net/manual/en/features.file-upload.errors.php
i try to upload image to phpmyadmin server but in every time i get same error first error : Notice: Undefined index: image_path in /storage/ssd2/750/2564750/public_html/hi.php on line 12
Your Image Has Been Uploaded.
image is uploaded to server but its size =0 "zero"
php code
<?php
include 'DatabaseConfig.php';
// Create connection
$conn = new mysqli($HostName, $HostUser, $HostPass, $DatabaseName);
if($_SERVER['REQUEST_METHOD'] == 'POST')
{
$DefaultId = 0;
$ImageData = $_POST['image_path'];
$ImageName = $_POST['image_name'];
$GetOldIdSQL ="SELECT id FROM UploadImageToServer ORDER BY id ASC";
$Query = mysqli_query($conn,$GetOldIdSQL);
while($row = mysqli_fetch_array($Query)){
$DefaultId = $row['id'];
}
$ImagePath = "images/$DefaultId.png";
$ServerURL = "https://xxxxx.000webhostapp.com/$ImagePath";
$InsertSQL = "insert into UploadImageToServer (image_path,image_name) values ('$ServerURL','$ImageName')";
if(mysqli_query($conn, $InsertSQL)){
file_put_contents($ImagePath,base64_decode($ImageData));
echo "Your Image Has Been Uploaded.";
}
mysqli_close($conn);
}else{
echo "Not Uploaded";
}
?>
my database (id, image_path,image_name) both path and name datatype is text
i use postman to test my test like the following

I have a problem, because the picture isnt sent to my database. I used different PHP file which doesnt decode picture again and everything works fine, all results appear in my database, but when I try to connect to that file it doesnt work. This is the php that doesnt work properly:
<?php
header('Content-type : bitmap; charset=utf-8');
if(isset($_POST["encoded_string"])){
$username = $_POST["username"];
$description = $_POST["description"];
$encoded_string = $_POST["encoded_string"];
$decoded_string = base64_decode($encoded_string);
$path = 'place on server where I want pictures to be sent' ;
$file = fopen($path, 'wb');
$is_written = fwrite($file, $decoded_string);
fclose($file);
if($is_written > 0){
$con = mysqli_connect("localhost", "xx", "xx", "xx");
$query = "INSERT INTO meals(username, description, image) values('$username', '$description' , '$path');";
$result = mysqli_query($con, $query);
if($result){
echo "success";
}else{
echo "failed";
}
mysqli_close($con);
}
}
?>
And that one send details properly but not in the way I would like to:
<?php
$con = mysqli_connect("localhost", "xx", "xx", "xx");
$username = $_POST["username"];
$description = $_POST["description"];
$encoded_string = $_POST["encoded_string"];
$statement = mysqli_prepare($con, "INSERT INTO images (username, description, image)
VALUES (?, ?, ?)");
mysqli_stmt_bind_param($statement, "sss", $username, $description, $encoded_string);
mysqli_stmt_execute($statement);
$response = array();
$response["success"] = true;
echo json_encode($response);
?>
Is it casued beacause I have to change FTP settings?
the second code passes all data to database but image is in base64 format so there are plenty characters and it runs slowly. What I want to do is to be able to use the first code, but it doesn't decodes base64 to actual image I am sending and it shows no result in database nor folder in server.
Try this:
$encoded_string = $_POST["encoded_string"];
$path="uploads"."/".rand()."_".time().".jpeg"; //uploads is folder, file name is composed of random number+underscore+time.jpeg
$upload_url="http://xxx.xx.xx.xx/".$path;
if(file_put_contents($path,base64_decode($encoded_string))){
//file uploaded, insert $upload_url into database(Type varchar)
}else{
//echo "file could not uploaded";
}
I am trying to upload image from android app using Google Volley to the server but for some reason the SQL command to insert the URL to database and upload doesn't work. The rest of the commands as well as the code in android seems to be working. But the response is incorrect. Check the else statement below highlighted by comment, that statement is executed for some reason whatever I do.
<?php
if($_SERVER['REQUEST_METHOD']=='POST'){
$image = $_POST['image'];
$name = $_POST['name'];
...
$conn = mysqli_connect(HOST,USER,PASS,DB) or die('unable to connect to db');
$sql ="SELECT id FROM volleyupload ORDER BY id ASC";
$res = mysqli_query($conn,$sql);
$id = 0;
while($row = mysqli_fetch_array($res)){
$id = $row['id'];
}
$path = "uploads/$id.png";
$actualpath = "http://myurl.co/prak/$path";
$sql = "INSERT INTO volleyupload (photo,name) VALUES ('$actualpath','$name')";
if(mysqli_query($conn,$sql)){
file_put_contents($path,base64_decode($image));
echo "Successfully Uploaded";
} else{
echo "ERROR in insertion to DB!"; //THIS ERROR COMES UP
}
mysqli_close($conn);
}else{
echo "Error";
}
?>
The tutorial I am following for volley image upload is here: https://www.simplifiedcoding.net/android-volley-tutorial-to-upload-image-to-server/
Please let me know what's the problem and if there is an issue with the question do let me know that as well.
Fact that else branch is always entered means that mysqli_query($conn,$sql) function result is FALSE.
This is most likely caused by problem with your SQL statement. Fortunately there is a way to find out where exactly the problem origins - you can use mysqli_error($conn) to find out where the issue is exactly.
Possibly by adjusting your code to something like this:
if(mysqli_query($conn,$sql)){
file_put_contents($path,base64_decode($image));
echo "Successfully Uploaded";
} else{
echo "ERROR in insertion to DB:" . mysqli_error($conn); //THIS ERROR COMES UP
}
