Question

I have the following function that is called when I click on a button to submit a form:

    function dadosFormularios(preenchimentoForm){
    //var path = document.location.pathname;
    //alert(path);
    alert(preenchimentoForm);
    //window.location.href = 'wp-content/themes/template/index.php'; 

    var qstringA = '';
    //dados dos campos
    var nome=document.getElementById("nome").value;
    qstringA = 'nome='+ nome;
    //alert(qstringA);

    if(preenchimentoForm==false){
        alert('Please correct the errors in the Form'); 
    }
    else{
        if(preenchimentoForm==true){
            window.location.href = 'index.php?'+qstringA;
        return false;
        }
    }
}

Since I’m using this way of processing the data, how can I alert my page index.php that the data sent by the function arrived on the index? I can’t use a if (isset($_POST['button']..) since I send the information by the function and not through the button of the form, right?

Answer 1

window.location.href = 'index.php?'+qstringA;
This line is just redirecting to index.php with a query string ?nome=nome_value.
For example. index.php?nome=nome_value

So, in your index.php You can simply get everything posted with $_GET.

Check it by doing a print_r($_GET); there.

In index.php, you can simply check

if(isset($_GET["nome"])){
    //Nome is set
    //Do something here
}

P.S. Although, without knowing the other circumstances or reasons behind usage of this function, it can be said that this function is just doing what a simple <form action=index.php> would have done.

P.P.S. Although you have mentioned jQuery in title and also tagged it, I am not sure this function is using any of the jQuery code. I think it is just a simple Javascript function.
