人々から提供されたコードを変更すると、Androidで非常にうまく動作するという問題に直面しています。しかし..それは何の応答もデータベースも与えません..行は関数の後も同じままです..私がした間違いは何ですか? ありがとう!
Android コードは次の場所にあります。
public class MainActivity extends Activity {
private ProgressDialog pDialog;
Uri currImageURI;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button gallery_btn = (Button)findViewById(R.id.gallerybtn);
gallery_btn.setOnClickListener(new OnClickListener(){
public void onClick(View view){
//to open up a gallery browser
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture.."),1);
}
});
Button upload_btn = (Button)findViewById(R.id.uploadbtn);
upload_btn.setOnClickListener(new OnClickListener(){
public void onClick(View view){
new HttpUploader().execute(getRealPathFromURI(currImageURI));
}
});
}
// To handle when an image is selected from the browser
public void onActivityResult(int requestCode, int resultCode, Intent data){
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
// currImageURI is the global variable I’m using to hold the content:
currImageURI = data.getData();
EditText tv_path = (EditText) findViewById(R.id.path);
tv_path.setText(getRealPathFromURI(currImageURI));
}
}
}
//Convert the image URI to the direct file system path of the image file
public String getRealPathFromURI( Uri contentUri) {
String [] proj={MediaStore.Images.Media.DATA};
android.database.Cursor cursor = managedQuery(contentUri,
proj, // Which columns to return
null, // WHERE clause; which rows to return (all rows)
null, // WHERE clause selection arguments (none)

Logcat はこれだけを示します: log_tag ** ", "良い接続
PHP ファイルは次の場所にあります。
<?php
include "db_connection.php";
if (isset($base)) {
$base = $_REQUEST["image"];
$filepath = $_REQUEST["path"];
$id = $_REQUEST["id"];
$image_name = "/image/".$filepath;
// base64 encoded utf-8 string
$binary = base64_decode($base);
// binary, utf-8 bytes
header("Content-Type: bitmap; charset=utf-8");
$file = fopen($image_name, "wb");
fwrite($file, $binary);
fclose($file);
$result = mysql_query("UPDATE restaurants SET image = '$image_name' WHERE ID = '$id'");
if(mysql_affected_rows > 0){
echo json_encode("success!");
}else{
echo json_encode("failed!");
}
} else {
echo json_encode("missing required attribute!");
}
?>
