I'm starting my PHP studies and I have to do a registration form, however, it's very bad to do data validation via PHP, so I'm using jQuery for this.
However, I need to call the PHP function inside jQuery to just get data that has already been validated. How can I do this?
Request via AJAX with jQuery.
We are accessing a file http://exemplo.com/funcoes.php , assuming it is in the same directory, it is possible to access links. A very simple example, this is the HTML file:
<script>
$( "form" ).submit(function( event ) {
event.preventDefault();
$.ajax({
url : 'funcoes.php',//url para acessar o arquivo
data: {id : 10},//parametros para a funcao
type : 'post',//PROTOCOLO DE ENVIO PODE SER GET/POST
dataType : 'json',//TIPO DO RETORNO JSON/TEXTO
success : function(data){//DATA É O VALOR RETORNADO
alert(data.valor);//VALOR INDICE DO ARRAY/JSON
},
});
});
</script>
and the file funcoes.php
<?php
//funcao retornando um json
function teste(){
echo json_encode(array('valor' => $_POST['id']));
}
//executando a funcao
teste();
?>
