Upload multiple images to webservice using PHP

Question

I am new to webservice using PHP for an Android device. I need to work on the concept of uploading multiple images. Please suggest. I implemented a single upload concept, below is the code for downloading a single file.

$data = $_REQUEST;
if($data["prop_images"]){       
            $filename = md5(time()).'.jpg';
            $base=$data["prop_images"];
            $binary = base64_decode($base);         
            $pathtoupload = JPATH_ADMINISTRATOR . '/components/com_clinchproperties/galupload/';
            //header('Content-Type: bitmap; charset=utf-8');  // binary, utf-8 bytes
            $actual_image_name = time().".jpg";
            $image = $filename;
            $file = fopen($pathtoupload.$filename,  'wb');
            fwrite($file, $binary);
            fclose($file);
        }

I need code to upload n number of images at a time. Can anyone help me with this? Thanks in advance.

Answer 1

You need to transfer an array of files. As you noted in the comment, you are sending the file data in base64 format, try the following code for PHP.

Php

  $data = $_REQUEST;
  if($data["prop_images"]){ 
    foreach($data["prop_images"] as $img){ //array of images. So loop for every images
        $filename = md5(time()).'.jpg';
        $base=$img;
        $binary = base64_decode($base);         
        $pathtoupload = JPATH_ADMINISTRATOR . '/components/com_clinchproperties/galupload/';
        $actual_image_name = time().".jpg";
        $image = $filename;
        $file = fopen($pathtoupload.$filename,  'wb');
        fwrite($file, $binary);
        fclose($file);
    }
  }

Android [] POST. prop_images[] .

Android, Android.

Android

HttpClient httpClient = new DefaultHttpClient();

HttpPost postRequest = new HttpPost("http://webserver.com/path/to/webservice.php");

MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);

for (int i = 0; i < number_of_images; i++) {
    //convert your images to base64 and store in base64ImageData.
    reqEntity.addPart("prop_images[]", base64ImageData);   //adding parameter
}

//execute request.
