从android中将多个图像保存到mysql php中，但只插入一个图像

Question

I have three list view in Activity A as below

When the submit button is clicked, the text and image path will be saved into MySQL and the image will be stored in PhotoUpload folder.

I'm able to stored 3 text into MySQL but the problem is only one path of the image is saved into MySQL . Between, the image suppose to save inside PhotoUpload but it just save outside the folder !

It totally frustrating !

Activity A

  public void uploadImageAndText(ArrayList<ImageAndText> listItems, final String id) { // Assume id holds value 2 (ts_id)
            JSONArray jsonArray = new JSONArray();

        }
    }
?>

Output

I check the image path and three of them are the same ! And only one image(2.png) saved, and it is outside the PhotoUpload, not inside :(

path problem ? java problem ? or php problem ???

Answer 1

First of all you are overwriting the image data in you doInBackground loop.

Second the PHP upload code is not in the loop

JAVA

You should have only one loop, when you build your JSON, put everything you need there

for (ImageAndText i : listItems) {
    JSONObject object = new JSONObject();

    String type = i.getType();
    String[] Type = type.split(":");
    String amount = i.getAmount();
    String[] Amount = amount.split(":");
    String description = i.getDescription();
    String[] Description = description.split(":");

    //Image
    String image = i.getImage().toString()
    Uri imageUri = Uri.parse(image);

    object.put("amount", Amount[1]);
    object.put("type", Type[1]);
    object.put("description", Description[1]);
    object.put("ts_id", id);
    object.put("image", image);
    object.put(Configs.KEY_IMAGE, getStringImage(imageUri));

    jsonArray.put(object);
}

Then put the JSON in your hashmap to send

@Override
protected String doInBackground(String... params) {
    try {
        HashMap<String, String> data = new HashMap<String, String>();
        data.put("listItems", jsonArray.toString());

        RequestHandler rh = new RequestHandler();
        String result = rh.sendPostRequest(Configs.STAFF_BENEFIT, data);
        return result;
    } catch (Exception e) {
        return "";
    }
}

PHP

The php would change, you won't need $image = $_POST['image'];

You will get the image data from the json $listItems = json_decode( $_POST['listItems'], true );

You would put the upload code in the loop , and insert only on successful upload

foreach( $listItems as $item ){ 
    $path=time()."$id.png";
    $actualpath="http://192.168.107.115:80/Android/CRUD/PhotoUpload/$path";
    $bytes=file_put_contents( $savepath, base64_decode( $item['image'] ) );
    if( !$bytes ){
        echo 'Error saving image';  
    }else{
        $stmt->bind_param('sssss', 
        $item['type'], 
        $item['amount'], 
        $item['description'], 
        $actualpath, 
        $item['ts_id'] );
        $res=$stmt->execute();
        if( !$res ) echo 'Query failed with code: '.$stmt->errno;
    }
} 

EDIT:

Full PHP script

<?php
    if( $_SERVER['REQUEST_METHOD']=='POST' ){
        if( !empty( $_POST['listItems'] ) ){
            $listItems = json_decode( $_POST['listItems'], true ); 
            $mysqli = new mysqli("127.0.0.1:3307", "root", "", "androiddb");
            if( $mysqli->connect_errno ) echo "Failed to connect to MySQL";
            $sql="INSERT INTO `staff_benefit` 
                 ( `type`, `amount`, `description`, `image`, `ts_id` ) 
                  VALUES ( ?, ?, ?, ?, ? )";
            if($stmt=$mysqli->prepare($sql )){
                $url="http://192.168.107.115:80/Android/CRUD/PhotoUpload/";
                foreach( $listItems as $item ){ 
                    $image_name = time().".png";
                    $save_path = 'PhotoUpload/'.$image_name;
                    $image_url = $url.$image_name;
                    $bytes=file_put_contents($save_path, base64_decode($item['image']));
                    if( !$bytes ){
                        echo 'Error saving image';  
                    }else{
                        $stmt->bind_param('sssss', 
                        $item['type'], 
                        $item['amount'], 
                        $item['description'], 
                        $image_url, 
                        $item['ts_id'] );
                        if( !$res=$stmt->execute()){ 
                            echo 'Query failed with code: '.$stmt->errno;
                        }
                    }
                } 
            }
            $mysqli->close();
        }
    }
