我已经阅读了很多关于将图像上传到服务器的帖子，但我仍然有问题。图像成功存储在我的文件夹路径中，但是当我在phpmyadmin中打开我的数据库表时，图像并没有存储在那里。
我的问题是，在图像成功存储在目标文件夹中后，如何修改代码以将图像路径另外保存到MySql数据库中？请帮忙。
对于completition，我正在显示当前代码以将图像上传到服务器：
upload.java：
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1 && resultCode == RESULT_OK) {
//Bitmap photo = (Bitmap) data.getData().getPath();
Uri selectedImageUri = data.getData();
imagepath = getPath(selectedImageUri);
Bitmap bitmap=BitmapFactory.decodeFile(imagepath);
imageview.setImageBitmap(bitmap);
messageText.setText("Uploading file path:" +imagepath);
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
public int uploadFile(String sourceFileUri) {
String fileName = sourceFileUri;
HttpURLConnection conn = null;
DataOutputStream dos = null;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 512 * 512;
File sourceFile = new File(sourceFileUri);
if (!sourceFile.isFile()) {
pDialog.dismiss();
Log.e("uploadFile", "Source File not exist :"+imagepath);
runOnUiThread(new Runnable() {
public void run() {
messageText.setText("Source File not exist :"+ imagepath);
}
});
return 0;
}
else
{
try {
// open a URL connection to the Servlet
FileInputStream fileInputStream = new FileInputStream(sourceFile);
URL url = new URL(upLoadServerUri);
// Open a HTTP connection to the URL
conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true); // Allow Inputs
conn.setDoOutput(true); // Allow Outputs
conn.setUseCaches(false); // Don't use a Cached Copy
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("ENCTYPE", "multipart/form-data");
conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
conn.setRequestProperty("uploaded_file", fileName);
dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\""
+ fileName + "\"" + lineEnd);
dos.writeBytes(lineEnd);
// create a buffer of maximum size
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
// read file and write it into form...
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0) {
dos.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
// send multipart form data necesssary after file data...
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
// Responses from the server (code and message)
serverResponseCode = conn.getResponseCode();
String serverResponseMessage = conn.getResponseMessage();
Log.i("uploadFile", "HTTP Response is : "
+ serverResponseMessage + ": " + serverResponseCode);
if(serverResponseCode == 200){
runOnUiThread(new Runnable() {
public void run() {
String msg = "File Upload Completed.\n\n See uploaded file here : \n\n"
+" D:/food/adminweb/foto_berbagi_masakan/";
messageText.setText(msg);
Toast.makeText(Berbagi_Resep.this, "File Upload Complete.", Toast.LENGTH_SHORT).show();
}
});
}
//close the streams //
fileInputStream.close();
dos.flush();
dos.close();
} catch (MalformedURLException ex) {
pDialog.dismiss();
ex.printStackTrace();
runOnUiThread(new Runnable() {
public void run() {
messageText.setText("MalformedURLException Exception : check script url.");
Toast.makeText(Berbagi_Resep.this, "MalformedURLException", Toast.LENGTH_SHORT).show();
}
});
Log.e("Upload file to server", "error: " + ex.getMessage(), ex);
} catch (Exception e) {
pDialog.dismiss();
e.printStackTrace();
runOnUiThread(new Runnable() {
public void run() {
messageText.setText("Got Exception : see logcat ");
Toast.makeText(Berbagi_Resep.this, "Got Exception : see logcat ", Toast.LENGTH_SHORT).show();
}
});
Log.e("Upload file to server Exception", "Exception : " + e.getMessage(), e);
}
pDialog.dismiss();
return serverResponseCode;
} // End else block
}
这适用于uploadToServer.php：
<?php
include '../config/koneksi.php';
$file_path = "adminweb/foto_berbagi_resep/";
$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
$link = mysql_connect($host,$database);
mysql_query($link, "INSERT INTO 'gambar_upload' (gambar) VALUES('".$file_path."')"); /*or trigger_error($link->error."[ $sql]");*/
mysql_close($link);
}
else{
echo "fail";
}
?>
答案 0 :(得分：0)
$link = mysql_connect($host,$database);
mysql_query($link, "INSERT INTO 'gambar_upload' (gambar) VALUES('".$file_path."')");
mysql_close($link);
它应该是这样的：
$link = mysqli_connect("myhost","myuser","mypassw","mybd");
$filepath = mysqli_real_escape_string($link, $file_path);
$query = "INSERT INTO 'gambar_upload' (gambar) VALUES('".$filepath."')";
mysqli_query($link, $query);
mysqli_close($link);
另一个例子可以在这里找到：http://php.net/manual/de/mysqli.real-escape-string.php
