I do not know if it is possible, but I would like to create a link (or simulate one) where I need to pass data to the page of that link, but I would not like to pass this data by get but by post , otherwise (I know that for an advanced user it will be possible to see this data, but there would be no problem).

Below the link I'm creating:

<a href="pagina_a_ser_chamada" data-usuario="1" data-cliente="3" class="openLink">
    Abrir dados do cliente 3
</a>

<a href="pagina_a_ser_chamada" data-usuario="1" data-cliente="4" class="openLink">
    Abrir dados do cliente 4
</a>

<a href="pagina_a_ser_chamada" data-usuario="1" data-cliente="5" class="openLink">
    Abrir dados do cliente 5
</a>

I tried to do something with jQuery, but I could not pass the data usuario and cliente and not I want to have to pass pagina_a_ser_chamada?usuario=1&cliente=3

$(document).ready(function() {
    $('.openLink').click(function(event) {
        event.preventDefault();
        window.open($(this).attr('href'), '_blank');
    });
});

jquery link

This question is very interesting, I recommend making the solution using a form, which can be hidden from the user.

It does not come to mind how to open a new tab using a POST without the use of a form.

Edit: Using the target="_blank" attribute makes it possible to open the page in a new window / tab, but I mistakenly understood that it was mandatory, but it is not.

Form to use:

<form action="#" method="post" style="display:none" id="transport">
    <input type="hidden" name="usuario" />
    <input type="hidden" name="cliente" />
</form>

In the form I put two inputs based on the custom attributes of the link, but if you want you can create the inputs as needed, either in HTML or via JavaScript.

Link to be clicked:

<a href="pagina_a_ser_chamada" data-usuario="1" data-cliente="3" class="openLink">
    Clique aqui
</a>

Javascript:

function extractData(link) {
    var obj = {},
        attributes = link.attributes,
        count = attributes.length;

    for(var i = 0; i < count; ++i) {
        var prefixLocation = attributes[i].name.search('data-');

        if(prefixLocation != -1) {
            obj[attributes[i].name.substr(prefixLocation + 5)] = attributes[i].value;
        }
    }

    return obj;
}

$(document).ready(function() {
    $('.openLink').click(function(event) {
        event.preventDefault();

        $form = $('#transport');

        // Extrai os dados dos atributos customizados do link tirando o prefixo "data-"
        var data = extractData(this); 

        // Preenche os dados no form
        for(var attr in data) {
            $form.find('input[name="' + attr + '"]').val(data[attr]);
        }

        // Atualiza o action do form com o href do link
        $form.attr('action', this.href);

        // Submete o form
        $form.submit();
    });
});

The example can be seen in this JSFiddle , but it does not work in this environment because of security and cross-domain rules, it is just a place to see the form filling in HTML.

To see the result, I recommend testing in a more real-world environment.

Only POST can be sent via forms, server-side or gambiarra xD

<form action="pagina_a_ser_chamada" method="post">
    <input type="hidden"  name="usuario" value="1" />
    <input type="hidden"  name="cliente" value="3" />
    <input type="submit" class="openLink" value="Clique aqui" />
</form>

If you are using PHP try session variables

$_SESSION['usuario'] = 1;
$_SESSION['cliente'] = 3;

These variables can be seen anywhere in your code, and the user of your site will not be able to see ...

=)

You can use url segments

$_SERVER['REQUEST_URI_PATH'] = parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH);
$segments = explode('/', $_SERVER['REQUEST_URI_PATH']);

The variable $segments contains for example localhost / site / page

array 
  0 => string 'localhost' 
  1 => string 'site' 
  2 => string 'pagina'

With this method the links would be as follows

<a href="pagina_a_ser_chamada/1/4" class="openLink">
    Abrir dados do cliente 4
</a>
