【问题描述】：
我有这个代码：
<?php include('konek.php');
$entid=$_POST['entId'];
$entSender=$_POST['entSender'];
$entTitle=$_POST['entTitle'];
$entDate=$_POST['entDate'];
$entSAGrade=$_POST['entSAGrade'];
$entReason=$_POST['entReason'];
$entProblem=$_POST['entProblem'];
$entTime=$_POST['entTime'];
if($row_num != 0)
{
$ins=mysql_query("INSERT into tblentry(entId,entSender,entTitle,entTime,entSAGrade,entReason,entProblem) VALUES('$entId','$entSender','$entTitle',CURTIME(),'$entSAGrade','$entReason','$entProblem')");
echo "Added"; }
else
{ echo "Added."; }
?>
我的问题是，当我在我的 android 模拟器中输入数据时，它没有添加。我的代码有什么问题？
这是我在 android 中的代码：
public class AddEntry extends Activity {
Button buttonSave;
EditText ent1, ent2, ent3, ent4, ent5, ent6 ;
HttpPost httppost;
HttpResponse response;
HttpClient httpclient;
List<NameValuePair> nameValuePairs;
ProgressDialog dialog = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.addentry);
buttonSave = (Button)findViewById(R.id.Save);
ent1 = (EditText)findViewById(R.id.entSender);
ent2 = (EditText)findViewById(R.id.entDate);
ent3 = (EditText)findViewById(R.id.entTitle);
ent4 = (EditText)findViewById(R.id.entSAGrade);
ent5 = (EditText)findViewById(R.id.entReason);
ent6 = (EditText)findViewById(R.id.entProblem);
buttonSave.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
dialog = ProgressDialog.show(AddEntry.this, "",
"Adding entry. . .", true);
new Thread(new Runnable() {
public void run() {
insertEntry();
}
}).start();
}
});
}
void insertEntry(){
try{
httpclient=new DefaultHttpClient();
httppost= new HttpPost("http://10.0.2.2/smcfi/insertentry.php"); // make sure the url is correct.
//add your data
nameValuePairs = new ArrayList<NameValuePair>(6);
// Always use the same variable name for posting i.e the android side variable name and php side variable name should be similar,
nameValuePairs.add(new BasicNameValuePair("enSender",ent1.getText().toString().trim())); // $Edittext_value = $_POST['Edittext_value'];
nameValuePairs.add(new BasicNameValuePair("entDate",ent2.getText().toString().trim()));
nameValuePairs.add(new BasicNameValuePair("entTitle",ent3.getText().toString().trim()));
nameValuePairs.add(new BasicNameValuePair("entSAGrade",ent4.getText().toString().trim()));
nameValuePairs.add(new BasicNameValuePair("entReason",ent5.getText().toString().trim()));
nameValuePairs.add(new BasicNameValuePair("entProblem",ent6.getText().toString().trim()));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
//Execute HTTP Post Request
response=httpclient.execute(httppost);
// edited by James from coderzheaven.. <span id="IL_AD10" class="IL_AD">from here</span>....
ResponseHandler<String> responseHandler = new BasicResponseHandler();
final String response = httpclient.execute(httppost, responseHandler);
System.out.println("Response : " + response);
runOnUiThread(new Runnable() {
public void run() {
// tv.setText("Response from PHP : " + response);
dialog.dismiss();
}
});
if(response.equalsIgnoreCase("Added")){
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(AddEntry.this,"Successfully Added.", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(AddEntry.this, Entry.class);
AddEntry.this.startActivity(intent);
AddEntry.this.finish();
}
});
}else{
showAlert();
}
}catch(Exception e){
dialog.dismiss();
System.out.println("Exception : " + e.getMessage());
}
}
public void showAlert(){
AddEntry.this.runOnUiThread(new Runnable() {
public void run() {
AlertDialog.Builder builder = new AlertDialog.Builder(AddEntry.this);
builder.setTitle("Error");
builder.setMessage("Not Added.")
.setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
});
AlertDialog alert = builder.create();
alert.show();
}
});
}
@Override
public void onBackPressed() {
Intent intent = new Intent(AddEntry.this, MainAct.class);
AddEntry.this.startActivity(intent);
AddEntry.this.finish();
}
}
我不知道是什么错误。但它没有添加。我输入的数据没有添加到我的数据库中。

您的查询中有语法错误。应该是：
$ins=mysql_query("INSERT into tblentry(entId,entSender,entTitle,entTime,entSAGrade,entReason,entProblem) VALUES('$entId','$entSender','$entTitle',CURTIME(),'$entSAGrade','$entReason','$entProblem')");另外，不推荐使用 mysql_*，请改用 mysqli :)。此外，在您的查询之后，您可以添加or die (mysql_error());，即使上面的错误应该归类为语法错误。
