I tried to connect to the database, but the database is only saving the ID of the user.

{$con = mysql_connect("localhost","root", "");

mysql_select_db("cadastro",$con);

$nome = $_POST['nome'];
$email = $_POST['email'];
$senha = $_POST['senha'];
$tdc = $_POST['tdc'];
$sql = mysql_query("INSERT INTO tb_usuarios(nome_usuario, email_usuario, senha_usuario, tdc_usuario) VALUES ('$nome', '$email', '$senha', '$tdc')");
?>}

After registration you are giving these errors:

{Notice: Undefined index: nome in C:\xampp\htdocs\Controla\cadastrando.php on line 19

Notice: Undefined index: email in C:\xampp\htdocs\Controla\cadastrando.php on line 20

Notice: Undefined index: senha in C:\xampp\htdocs\Controla\cadastrando.php on line 21

Notice: Undefined index: tdc in C:\xampp\htdocs\Controla\cadastrando.php on line 22}

How to add a unique constraint on a column without deleting the table or column Ajax GET Autocomplete Problem

score 0 · Accepted Answer

The error is because you are redirecting the user (via the <a> tag, instead of sending the form data.

There are 3 ways to submit form data:

Button

<button type="submit">Cadastrar</button>
Input Submit

<input type="submit" value="Cadastrar" />
Ajax

link

To fix just replace:

<a href="cadastrando.php"><img src="imagens/Botão.png" style="margin-left: -2px; margin-top: -1em; cursor: pointer;"></a>

By:

<button type="submit">Cadastrar</button>

Or:

<button type="submit" style="background:url('imagem.png');height:75px;width:75px"></button>
