Ajax response from php

[gmc1103]

Hi

 

I'm having problem (no response is received in my html page) with ajax

 

This is the php with echo

echo json_encode(array('status' => 'success', 'message' => 'Nova formação gravada'));

And this is my ajax

<script type="text/javascript">
            $.ajax({
                url: 'nova_formacaoBD.php',
                data: {
                   format: 'json'
                },
                error: function() {
                   $("#ajaxDivErro").html('Esta formação já está registada na base de dados');
                },
                dataType: 'json',
                success: function(data) {
                   $('#ajaxDivOk').html('Informação: Esta formação foi registada na base de dados');  
                },
                type: 'GET'
             });
        </script>

So after inserting the data into my database i would like to receive the response to a div.

 

 

Whats wrong?

 

Thanks

What does your browsers console say? Is the request making it to the script?

Assuming that you are actually getting the json response back from the server, you're not doing anything with it in your ajax success block.  You could do something like this with the returned message.

success: function(data) {
   $('#ajaxDivOk').html('Informação: Esta formação foi registada na base de dados');
   if(data.status == "success"){ // That is the json returned success in your array with message
      $('#ajaxDivOk').append(data.message);
   }
}

In console i don't get anything but i receive the json response in the browser in json format

If you don't see anything in the console, you may need to switch to the network activity tab. It depends what console you are using. How do you know that you are receiving the json response?

Hi

 

This is the response in console

 

{"status":"success","message":"Nova forma\u00e7\u00e3o gravada"}

 

So i receive the the json array

 

The problem is i don't stay in my page form (/superNewFormacao.php) and i get the response from my insert php file (nova_formacaoBD.php)

 

This is my php

<?php

header('Content-Type: application/json');
error_reporting(E_ALL | E_NOTICE);
ini_set('display_errors', '1');

$mysqli = new mysqli('localhost', 'xxxxxx', 'xxxxxxx');
if (mysqli_connect_errno()) {
    trigger_error('Database connection failed: ' . mysqli_connect_error(), E_USER_ERROR);
}

$uploaddir = $_SERVER['DOCUMENT_ROOT'] . '/uploads';
$uploadfile = $uploaddir . '/' . basename($_FILES['fileToUpload']['name']);
$escola = $_POST['escola'];
$form = $_POST['form'];
$data = $_POST['data'];
$horas = $_POST['horas'];
$local = $_POST['local'];
$dest = $_POST['dest'];
$datas = $_POST['datas'];
$visto = 0;


if (move_uploaded_file($_FILES['fileToUpload']['tmp_name'], $uploadfile)) {
    
    $target_path = "/uploads/" . basename($_FILES['fileToUpload']['name']);
    $sql = "INSERT INTO `ebspma_paad_ebspma`.`formacoes`(idescola, nome, inicio, horas, local, destinatarios, dataLimite, visto, path) VALUES(?, ?, ?, ?, ? ,?, ?, ?, ? )";
    $stmt = $mysqli->prepare($sql);
    if ($stmt === false) {
        trigger_error('Wrong SQL: ' . $sql . ' Error: ' . $mysqli->error, E_USER_ERROR);
    }
    $stmt->bind_param('issssssis', $escola, $form, $data, $horas, $local, $dest, $datas, $visto, $target_path);
    if (!$stmt->execute()) {
        echo json_encode(array('status' => 'error', 'message' => 'Opppss...A formação não foi gravada'));
    }
} else {
    echo json_encode(array('status' => 'error', 'message' => 'Opppss...A formação não foi gravada'));
}
$stmt->close();
echo json_encode(array('status' => 'success', 'message' => 'Nova formação gravada'));

And this is my form

  <form action="nova_formacaoBD.php" method="post" id="formacao" name="formacao" enctype="multipart/form-data">
                        <div class="form-group">
                            <label for="exampleInputFile">Escola: </label>
                            <select class="form-control" id="escola" name="escola" onchange="verificaEscola()">
                                <?php echo $escolaOptions; ?>
                            </select>   
                        </div>
                        <div class="form-group">

It sounds like you need to use preventDefault in your javascript to keep the HTML form from submitting.
