Good afternoon
I'm having difficulty retrieving the data in the database via checkbox.
<div class="container">
<div class="row">
<form action="resultado.php" multiple method="post">
<h3>Bairros</h3>
<p><input type="checkbox" name="bairro[]" value="Bairro de Fátima"/>Bairro de Fátima</p>
<p><input type="checkbox" name="bairro[]" value="Benfica"/>Benfica</p>
<p><input type="checkbox" name="bairro[]" value="Caju"/>Caju</p>
<p><input type="checkbox" name="bairro[]" value="Catumbi"/>Catumbi</p>
<p><input type="checkbox" name="bairro[]" value="Centro"/>Centro</p>
<input type="hidden" name="acao" value="Enviar"/>
<input type="submit" value="Enviar"/>
</form>

</div>
