首先,让我描述一下我在这里面临的问题。
我想存储从 android
到 MySQL
的图像路径,并将图像存储到 PhotoUpload 目录中。
当提交按钮被点击时,所有的listItem
将被保存到MySQL
。
Activity A
public void uploadImageAndText(ArrayList<ImageAndText> listItems, final String id) {
JSONArray jsonArray = new JSONArray();
try {
for (ImageAndText i : listItems) {
JSONObject object = new JSONObject();
String type = i.getType();
String[] Type = type.split(":");
object.put("type", Type[1]);
Toast.makeText(getApplicationContext(), Type[1], Toast.LENGTH_LONG).show();
String amount = i.getAmount();
String[] Amount = amount.split(":");
object.put("amount", Amount[1]);
String description = i.getDescription();
String[] Description = description.split(":");
object.put("description", Description[1]);
Bitmap uploadImage = i.getImage();
String image = getStringImage(uploadImage);
object.put("image", image);
object.put("ts_id", id);
jsonArray.put(object);
}
} catch (JSONException e) {
e.printStackTrace();
}
AddStaff ru = new AddStaff(jsonArray);
ru.execute();
}
class AddStaff extends AsyncTask<String, Void, String> {
ProgressDialog loading;
JSONArray jsonArray;
AddStaff(JSONArray jsonArray) {
this.jsonArray = jsonArray;
}
@Override
protected void onPreExecute() {
super.onPreExecute();
loading = ProgressDialog.show(AddClaims.this, "Please Wait", null, true, true);
}
@Override
protected String doInBackground(String... params) {
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;
}
@Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
loading.dismiss();
Toast.makeText(getApplicationContext(), s, Toast.LENGTH_LONG).show();
}
}
public String getStringImage(Bitmap bmp) {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] imageBytes = baos.toByteArray();
String encodedImage = Base64.encodeToString(imageBytes, Base64.DEFAULT);
return encodedImage;
}
}
php
<?php
if( $_SERVER['REQUEST_METHOD']=='POST' ){
if( !empty( $_POST['listItems'] ) ){
$mysqli = new mysqli("127.0.0.1:3307", "root", "", "androiddb");
if( $mysqli->connect_errno ) echo "Failed to connect to MySQL";
$image = $_POST['image'];
$listItems = json_decode( $_POST['listItems'], true );
$sql="SELECT id FROM staff_benefit ORDER BY id ASC";
$id=0;
$res=$mysqli->query( $sql );
while( $rs=$res->fetch_object() ) $id=$rs->id;
$path="$id.png";
$actualpath="http://192.168.107.115:80/Android/CRUD/PhotoUpload/$path";
$sql="INSERT INTO `staff_benefit` ( `type`, `amount`, `description`, `image`, `ts_id` ) VALUES ( ?, ?, ?, ?, ? )";
$stmt=$mysqli->prepare( $sql );
$pathelements=array( realpath( $_SERVER['DOCUMENT_ROOT'] ), 'CRUD', 'PhotoUpload', '' );
$savepath = realpath( implode( DIRECTORY_SEPARATOR, $pathelements ) ) . "{$id}.png";
$bytes=file_put_contents( $savepath, base64_decode( $image ) );
if( !$bytes ){
echo 'Error saving image';
}
if ( $stmt && $bytes ) {
foreach( $listItems as $item ){
$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;
}
}
$mysqli->close();
}
}
?>
这是我所期待的
错误
Undefined index: image in C:...... Error saving images
This is line 10
$image = $_POST['image'];
我知道我收到此错误消息是因为我只发布了 listItem
而没有发布图像。 我的问题是如何分解 listItem 中的图像然后对其进行解码?
有人可以帮助我如何将数组列表(带有图像)存储到 MySQL 中吗?非常感谢
我关注这个tutorial ,但问题是他存储的是单个文件,而不是 arrayList!
最佳答案
由于您在此 $image = $_POST['image'];
中未定义,为什么不添加 image
在你的doInBackground
?
试试这个
@Override
protected String doInBackground(String... params) {
HashMap<String, String> data = new HashMap<String, String>();
data.put("listItems", jsonArray.toString());
data.put(Configs.KEY_IMAGE,imagess);
RequestHandler rh = new RequestHandler();
String result = rh.sendPostRequest(Configs.STAFF_BENEFIT, data);
return result;
}
关于php - php中 undefined index 图像,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/34735076/
