I have the following code in Ajax:
<script>
$('#enviar').click(function() {
let dados
let filtros = document.getElementsByName('filtro[]');
let filtrosvalidos = [];
filtros.forEach(function(elemento, index){
if(elemento.checked){
filtrosvalidos.push(elemento.value)
}
})
let pesquisa = document.getElementById('pesquisa').value
let pesquisa2 = document.getElementById('pesquisa2').options[document.getElementById('pesquisa2').selectedIndex].value
let horaatual = document.getElementById('horaatual').value
$.ajax({
type : "POST",
url : "pesquisar.php",
crossDomain: true,
contentType: "application/json; charset=utf-8",
//dataType: 'json',
data:{
filtro: JSON.stringify(filtrosvalidos),
pesquisa: JSON.stringify(pesquisa),
pesquisa2: JSON.stringify(pesquisa2),
horaatual: JSON.stringify(horaatual),
},
success : function(responseData, textStatus, jqXHR) {
// dados = JSON.parse(responseData)
// processarDados(dados)
console.log(responseData);
}
});
});
And in php, the following code:
<?php
echo 'ok';
echo json_decode($_POST['filtro']);
?>
However, nothing leaves the console when I return php echo to ajax. Does anyone know why?
print_r(json_decode($_POST['filtro']));– Augusto Vasques
That’s not the problem, because json_decode returns a string, so echo would work the same way. But still, I test print_r and it returns me saying that the index 'filter' is undefined. If I put echo ($POST) it returns me an empty array, so I said on the question that I suspect that ajax is not sending the data to PHP.
