Fast Log In on every page

Create the script

Code:

$(function() {
    if (_userdata["session_logged_in"] == "0") {
        /* PERSONNALISATION DES TEXTES */
        var txt_username = "Username",
            txt_password = "Password",
            txt_login = "Log In",
            txt_remember = "Log in automatically",
            txt_guest = "Have you not registered yet ?",
            txt_create = "Register",
            txt_lost = "Have you forgotten your password ?",
            txt_recover = "Retrieve it";
        /* END OF PERSONALISATION - Do not modify the code below */
 
        $('body').prepend('<div id="quickloginform_overlay" style="display:none;z-index:2147483647"></div><div id="quickloginform" style="display:none;z-index:2147483647"><form id="fa-login-form" class="login-form" name="form_login" method="post" action="/login"><input type="text" maxlength="40" name="username" placeholder="' + txt_username + '" required=""><input type="password" maxlength="32" name="password" placeholder="' + txt_password + '" required=""><button name="login">' + txt_login + '</button><label><p>' + txt_remember + ' <input type="checkbox" style="vertical-align: middle;" name="autologin"></p></label><p style="float:left; text-align:left;">' + txt_guest + '<br><a href="/register">' + txt_create + '</a></p><p style="float:right; text-align:right;">' + txt_lost + '<br><a href="/profile?mode=sendpassword">' + txt_recover + '</a></p><div style="clear:both;"></div><input name="redirect" value="' + window.location.pathname + '" type="hidden"></form></div>');
 
        $('a[href*="/login"]').click(function() {
            $('#quickloginform, #quickloginform_overlay').fadeIn();
            $('#quickloginform input[name="username"]').focus();
            return false;
        });
 
        $(document).click(function(e) {
            if ($(e.target).closest('#quickloginform form').length === 0) {
                $('#quickloginform, #quickloginform_overlay').fadeOut();
            }
        });
        $(document).keyup(function(e) {
            if (e.keyCode == 27) {
                $('#quickloginform, #quickloginform_overlay').fadeOut();
            }
        });
    }
});

Personalise the script

Code:

var txt_username = "Username",
            txt_password = "Password",
            txt_login = "Log In",
            txt_remember = "Log in automatically",
            txt_guest = "Have you not registered yet ?",
            txt_create = "Register",
            txt_lost = "Have you forgotten your password ?",
            txt_recover = "Retrieve it";

Add the CSS

Code:

#quickloginform_overlay {
  background-color:#333;
  height:100%;
  left:0;
  opacity:0.7;
  position:fixed;
  top:0;
  width:100%;
}
#quickloginform {
