Uploading multiple images in webservice using PHP

问题:

I am new to webservice using PHP for Android device. I need to work on multiple image upload concept. Please suggest. I have implemented single upload concept the code for single file upload is given below.

$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 same time. Can any one help me with it? Thanks in advance.

You have to pass array of files. As you mentioned in comment, you are sending file data in base64 format, try 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);
    }
  }

In android code, make sure to add [] in parameter name while making POST request. That parameter should be prop_images[] as per example I given above.

I'm not an Android developer, but I can post code from our Android developer.

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.

This will help you to check your web service

<form method="post" enctype="multipart/form-data" action="audioupload.php">
 <input type="file" name="file1" multiple>
 <input type="submit"  value="OK">
</form>

audio.php
 <?php  
   move_uploaded_file($_FILES["file1"]["tmp_name"],"audio/".$_FILES["file1"]["name"]);   
  $url = "audio/".$_FILES["file1"]["name"];
  ?>

likewise developer can call this service n times.
