Hi,
I'm trying to send login datato php script, when click on submit button. I want to send data as Post for php script, via JSON.
This is my code on java file (piece of the form):
final TextBox mioUsername = new TextBox();
final PasswordTextBox miaPassword = new PasswordTextBox();
Button accedi = new Button();
//BUTTON SUBMIT
accedi.addClickHandler(new ClickHandler() {
publicvoid onClick(ClickEvent event) {
RequestBuilder request = new RequestBuilder(RequestBuilder.POST,URL.encode("checklogin.php"));
String name = mioUsername.getText();
String pssw = miaPassword.getText();
JSONObject jsonValue = new JSONObject();
jsonValue.put("myusername", new JSONString(name));
jsonValue.put("mypassword", new JSONString(pssw));
request.setHeader("Content-Type", "application/json");
try {
request.sendRequest(jsonValue.toString(),new RequestCallback() {
@Override
public void onResponseReceived(Request request, Response response) {
}
@Override
public void onError(Request request, Throwable exception) {
//displayError("Couldn't retrieve JSON");
}
});
} catch (com.google.gwt.http.client.RequestException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} });
and this is my php script:
<?php
$host="localhost"; // Host name
$username="usersuper"; // Mysql username
$password="passw"; // Mysql password
$db_name="Pippo"; // Database name
$tbl_name="Users"; // Table name
// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
// username and password sent from form
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];
$sql="SELECT * FROM $tbl_name WHERE Nome='$myusername' and Cognome='$mypassword'";
$result=mysql_query($sql);
// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
echo $count;
// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1){
// Register $myusername, $mypassword and redirect to file "login_success.php"
session_register("myusername");
session_register("mypassword");
header("location:login_success.php");
}
else {
echo "Wrong Username or Password";
}
?>
I don't know how must implement onResponseReceived method, to ensure that everything runs.
I need help.
Thanks
