Réponse JSON invalide de PHP?

Question

J'essaie d'analyser une réponse JSON à partir de mes fichiers PHP. Le premier AsyncTask renvoie des résultats valides, le second ne le fait pas. Je crois que le problème est dans mon "mysql_queries.php".

public class GeneralAssets extends ListFragment { 
View view; 
EditText cn, pn; 
ActionBar ab; 

private String url = "http://192.168.x.x/questions.php"; 
private String companyName, projectName;  

public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 

    view = inflater.inflate(R.layout.general_assets_questions, container, 
      false); 

    ab = getActivity().getActionBar(); 
    cn = (EditText)view.findViewById(R.id.company_input); 
    pn = (EditText)view.findViewById(R.id.project_input);  

    Button load = (Button) view 
      .findViewById(R.id.generalAssets_load_button_ID); 
    load.setOnClickListener(new View.OnClickListener() { 
     boolean large = getResources().getConfiguration() 
       .isLayoutSizeAtLeast(Configuration.SCREENLAYOUT_SIZE_LARGE); 

     @Override 
     public void onClick(View v) {    
      new LoadAllQuestions().execute(); 
     } 
    });   

    return view; 
} 

class LoadAllQuestions extends AsyncTask<String, String, String> { 

    private static final String TAG_SUCCESS = "success"; 
    private static final String TAG_QUESTIONS = "questions"; 
    private static final String TAG_NAME = "display_name"; 
    private static final String TAG_FIELD = "field_type"; 

    private ProgressDialog pDialog;  

    JSONParser jParser = new JSONParser(); 
    JSONArray questions = null; 

    ArrayList<HashMap<String, String>> questionsList = new ArrayList<HashMap<String,String>>(); 

    protected void onPreExecute() { 
     super.onPreExecute(); 
     pDialog = new ProgressDialog(getActivity()); 
     pDialog.setMessage("Loading questions. Please wait..."); 
     pDialog.setIndeterminate(false); 
     pDialog.setCancelable(false); 
     pDialog.show(); 
    } 

    protected String doInBackground(String... args) { 


     // getting JSON string from URL 
     companyName = cn.getText().toString(); 
     projectName = pn.getText().toString(); 
     String componentName = (String) ab.getSelectedTab().getText(); 

     List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(
       3); 
     nameValuePairs 
       .add(new BasicNameValuePair("company", companyName)); 
     nameValuePairs 
       .add(new BasicNameValuePair("project", projectName)); 
     nameValuePairs 
     .add(new BasicNameValuePair("component", componentName));   

     JSONObject json = jParser.makeHttpRequest(url, "POST", 
       nameValuePairs); 

     // Check your log cat for JSON reponse 
     Log.d("All Questions: ", json.toString()); 

     try { 
      // Checking for SUCCESS TAG 
      int success = json.getInt(TAG_SUCCESS); 

      if (success == 1) { 
       // products found: getting Array of Questions 
       questions = json.getJSONArray(TAG_QUESTIONS); 

       // looping through All Questions 
       for (int i = 0; i < questions.length(); i++) { 

        JSONObject c = questions.getJSONObject(i); 

        // Storing each json item in variable 
        String name = c.getString(TAG_NAME); 
        String field = c.getString(TAG_FIELD); 

        // creating new HashMap 
        HashMap<String, String> map = new HashMap<String, String>(); 

        // adding each child node to HashMap key => value 
        map.put(TAG_NAME, name); 
        map.put(TAG_FIELD, field); 

        // adding HashList to ArrayList 
        questionsList.add(map); 
       } 
      } else { 
       // no products found 
       // Launch Add New product Activity 
       Log.v("ERROR", "No JSON for you!"); 
      } 
     } catch (JSONException e) { 
      e.printStackTrace(); 
     } 
     return null; 
    } 

    protected void onPostExecute(String file_url) { 
     // dismiss the dialog after getting all products 
     pDialog.dismiss(); 

     // updating UI from Background Thread 
     getActivity().runOnUiThread(new Runnable() { 
      public void run() { 

       //Updating parsed JSON data into ListView      
       ListAdapter adapter = new SimpleAdapter(getActivity(), 
         questionsList, 
         R.id.genA_layout, 
         new String[] { TAG_FIELD, TAG_NAME }, 
         new int[] { R.id.answer, R.id.name }); 
       // updating listview 
       setListAdapter(adapter); 
      } 
     }); 
    } 
} 

} 

Le « SearchPosts » classe renvoie les éléments suivants dans les Log.v « résultats » String Quelle est la réponse JSON Je cherche.

{ 
    "questions": [ 
     { 
      "display_name": "Store #", 
      "field_type": "Text Field", 
      "option_value": "" 
     }, 
     { 
      "display_name": "Address", 
      "field_type": "Text Field", 
      "option_value": "" 
     }, 
     { 
      "display_name": "Type of Business", 
      "field_type": "Drop Down Menu", 
      "option_value": "Education\r\nHealth\r\nComputers\r\nFood\r\nRetail\r\nOther" 
     }, 
     { 
      "display_name": "Is this business good?", 
      "field_type": "Radio", 
      "option_value": "Yes\r\nNo" 
     }, 
     { 
      "display_name": "Are they nice people?", 
      "field_type": "Check Box", 
      "option_value": "Yes\r\nNo" 
     } 
    ], 
    "success": 1 
} 

Les "LoadAllQuestions" retourne la classe et s'écrase alors ce

Voici mes PHP fichiers

questions.php

<?php 

require 'connect.php'; 
require 'mysql_queries.php'; 

if ($query_run = mysql_query($questions_query)) { 
if (mysql_num_rows($query_run) == NULL) {

    $response ['questions'] = array();  
    while ($row = mysql_fetch_assoc($query_run)) {

     $info ['field_type'] = $row['field_type'];

$response["message"] = "No data found";

} 

?> 

mysql_queries

<?php 
require_once 'connect.php'; 

$company_name = $_POST['company']; 
$project_name = $_POST['project']; 
$component_name = $_POST['component']; 

$questions_query = "SELECT CFM.display_name, CFM.field_type, CFM.option_value 
       FROM company_mast 
       LEFT JOIN component_mast 
       ON company_mast.id = component_mast.company_id 
       LEFT JOIN CustomField_mast CFM 
       ON CFM.Company_ID = Component_mast.Company_ID 
       AND CFM.Component_ID = component_Mast.Component_ID 
       WHERE component_mast.component_name = '".$component_name."' 
       AND (component_mast.project_id = '".$project_name."' 
       OR company_mast.company_name = '".$company_name."')";     
?> 

Alors, pourquoi le premier AsyncTask retour une réponse valide et le 2e se présentent null? Ma supposition éclairée est que le POST sort de la portée au moment où la classe "LoadAllQuestions" essaie d'analyser la réponse JSON, mais je suis nouveau à cela et je ne sais pas comment le réparer.

Modifier
J'ai ajusté le code à partir des suggestions. Je reçois la bonne réponse JSON mais je reçois maintenant dans mon logcat.

Answer 1

changement

jParser.makeHttpRequest(url, "GET", 
      params); 

à

jParser.makeHttpRequest(url, "POST", 
      params); 

puis AVANT cette ligne, après l'initialisation de votre ArrayList, ajoutez ces valeurs au tableau, je suppose les mêmes leurs valeurs souhaitées SearchPost utilise ..

 String companyName = cn.getText().toString(); 
     String projectName = pn.getText().toString(); 
     String componentName = (String) ab.getSelectedTab().getText(); 

     List<NameValuePair> params = new ArrayList<NameValuePair>(); 
     params.add(new BasicNameValuePair("company", companyName)); 
     params.add(new BasicNameValuePair("project", projectName)); 
     params.add(new BasicNameValuePair("component", componentName)); 

EDIT: Initialisez la questionList par la suite.

questionList = ArrayList<HashMap<String, String>>(); 

EDIT 2:

changement

R.id.genA_layout 

à

R.layout.genA_layout 

MISE À JOUR

Vous devez créer un fichier de mise en page xml séparé en définissant le comportement de chaque ligne de vue de liste avec deux TextView avec des identifiants R.id.answer, R.id.name. Une simple maquette peut ressembler à ceci: (s'il vous plaît tester, j'ai codé cela directement à partir de la boîte de réponse).

MyListViewRow.xml

<LinearLayout 
    android:layout_height="wrap_content" 
    android:layout_width="match_parent" 
    android:orientation="vertical"> <!-- You can make orientation horizontal also --> 

    <TextView 
     android:id="@+id/answer" 
     android:layout_height="wrap_content" 
     android:layout_width="wrap_content"/> 

    <TextView 
     android:id="@+id/answer" 
     android:layout_height="wrap_content" 
     android:layout_width="wrap_content"/> 
</LinearLayout> 

Ensuite, changer R.id.genA_layout à R.layout.MyListViewRow

Answer 2

Vous utilisez une requête GET dans votre application Android, mais vous essayez d'obtenir des données POST dans votre code PHP. Je suppose que vous devez changer ceci:

jParser.makeHttpRequest(url, "GET", 
      params); 

à ceci:

jParser.makeHttpRequest(url, "POST", 
      params); 

Answer 3

Le second AsyncTask n'ajoute aucun paramètre à la demande entreprise à savoir, le projet et l'ajout component.In Vous ne vérifiez pas la existence des params dans la requête et comme mentionné dans la réponse @koesie vous devez changer le type de requête à POST au lieu de GET. Parce que vous envoyez une requête GET, les paramètres doivent être disponibles dans $ _GET, mais le code php vérifie les données $ _POST.

espoir que cela aiderait

Mise à jour Vous devez initialiser QuestionsListe

questionList = ArrayList<HashMap<String, String>>(); 

MISE À JOUR

ListAdapter adapter = new SimpleAdapter(getActivity(), 
         questionsList, 
         R.layout.genA_layout, 
         new String[] { TAG_FIELD, TAG_NAME }, 
         new int[] { R.id.answer, R.id.name }); 
       // updating listview 
       setListAdapter(adapter);
