php - Ajax error when retrieving data from JSON -

-

I am trying to send data to my PHP file which includes values ​​in DB (this part is fine) And then send back JSON. Encoded data in a javascript file, so that I can display them, but this is not working. I do not know what's actually wrong. I'm looking at many work examples and mines are not working

$ AZ ({type: "post", datatype: "jason", url: "requete.php", data: data, breakthrough: function (data) {if (data. Success == true) {warning (data. ;}}, Error: function (error thrown) {warning ('error');}});

The data is correctly sent to PHP and inserted in DB but the following JSN will not be displayed: 

  if (isset ($ _ POST) ['Action']) & Amp; $ _POST ['action'] == 'add_attribution') {$ nom = $ _POST ['name']; $ Date = $ _POST ['date']; $ Montant = (int) $ _ POST ['montant']; $ Type = utf8_decode ($ _ POST ['type']); Enter $ Sql ​​= "BO_DEPENCE (Montant, date, place, description, carte) value ('$ montent', '$ date', '', '$ name', '$ type')"; $ Result = mysql_query ($ sql); $ Data = array ('success' = & gt; true, 'message' = & gt; 'success message: hooray!'); Echo json_encode ($ data);

With this code, the console returns the "object" with the data sent to the console PHP / MySql (??)

) Warning (obj);

It turns out that it displays the first values ​​sent to my php script (to include in DB), and not that I'm JSON encoded ... why?

Try to use 

  if ($ .trim ( Data.success) == 1)

Sometimes I have encountered the only situation that I have solved

I have a form that has a property named car A class with many properties. The Properties is being displayed on the current car on the basis of some user actions that are being displayed. So I have to know whether the property has been allocated or set to zero. I'm aware of INotifyPropertyChanged , but in my case I'm not sure that since this change I have changed my car properties car do not want to monitor the property. Any idea how to accomplish this? In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
