First of all, I need to get the zip code down the street, that is, I do not have the zip code. and I have the address, I need to find the zip code by the address. So please do not relate this question with Search Street by Zip Code
Problem
I have PHP code that searches for streets by zip, however I need otherwise, I need to search zip through the street, city and state. Is this possible?
Important Information for Problem Solving
The WebService ViaCEP
It offers CEP and IBGE webservice for free, among the functions it also has to search the ZIP code on the street, however I can not adapt the functions in the code, the error or does not work, nothing appears.
In addition to leaving the street search code by zip, I'll also leave the função linked to how it works to search the street for the zip.
Search Street by Zip Code
Exemplo: viacep.com.br/ws/UF/Cidade/Rua/json/
Current Code
<html>
<head>
<title>ViaCEP Webservice</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<!-- Adicionando Javascript -->
<script type="text/javascript" >
function limpa_formulário_cep() {
//Limpa valores do formulário de cep.
document.getElementById('rua').value=("");
document.getElementById('bairro').value=("");
document.getElementById('cidade').value=("");
document.getElementById('uf').value=("");
document.getElementById('ibge').value=("");
}
function meu_callback(conteudo) {
if (!("erro" in conteudo)) {
//Atualiza os campos com os valores.
document.getElementById('rua').value=(conteudo.logradouro);
document.getElementById('bairro').value=(conteudo.bairro);
document.getElementById('cidade').value=(conteudo.localidade);
document.getElementById('uf').value=(conteudo.uf);
document.getElementById('ibge').value=(conteudo.ibge);
} //end if.
else {
//CEP não Encontrado.
limpa_formulário_cep();
alert("CEP não encontrado.");
}
}
function pesquisacep(valor) {
//Nova variável "cep" somente com dígitos.
var cep = valor.replace(/\D/g, '');
//Verifica se campo cep possui valor informado.
if (cep != "") {
//Expressão regular para validar o CEP.
var validacep = /^[0-9]{8}$/;
//Valida o formato do CEP.
if(validacep.test(cep)) {
//Preenche os campos com "..." enquanto consulta webservice.
document.getElementById('rua').value="...";
document.getElementById('bairro').value="...";
document.getElementById('cidade').value="...";
document.getElementById('uf').value="...";
document.getElementById('ibge').value="...";
//Cria um elemento javascript.
var script = document.createElement('script');
//Sincroniza com o callback.
script.src = '//viacep.com.br/ws/'+ cep + '/json/?callback=meu_callback';
//Insere script no documento e carrega o conteúdo.
document.body.appendChild(script);
} //end if.
else {
//cep é inválido.
limpa_formulário_cep();
alert("Formato de CEP inválido.");
}
} //end if.
else {
//cep sem valor, limpa formulário.
limpa_formulário_cep();
}
};
</script>
</head>
<body>
<!-- Inicio do formulario -->
<form method="get" action=".">
<label>Cep:
