Can't read cookies through PHP or Javascript when on an iPad

Question

I am currently having a few issues when trying to read cookies using PHP or Javascript. I have tried using:

if(!$_COOKIE['popup_closed']
&& !isset($_COOKIE['username'])
&& !isset($_COOKIE['password'])
)

And I have tried:

if(
$.cookie('popup_closed') == null
&& $.cookie('username') == null
&& $.cookie('password') == null) {
doStuff();
}

(Using the jquery.cookie plugin)

And neither of them work on iPad. It works on all browsers fine, I have tried Googling the issue but there dosen't seem to be much information on reading cookies on an iPad.

Thanks for any help you guys can give!

This is really a workaround, but you could use the local storage if it's available - atleast I've used it in iPad/iPhone successfully.

For example with this kind of solution.

function saveData(name, value) {
    if (typeof(localStorage) != 'undefined') {
        localStorage.setItem(name, value);
    } else {
        createCookie(name, value, 7);
    }
}

function loadData(name) {
    var temp_value = '';

    if (typeof(localStorage) != 'undefined') {
        temp_value = localStorage.getItem(name);
    } else {
        temp_value = readCookie(name);
    }

    return temp_value;
}

function eraseData(name) {
    if (typeof(localStorage) != 'undefined') {
        localStorage.removeItem(name);
    } else {
         eraseCookie(name);
    }

}

function createCookie(name,value,days) {
    var expires = "";

    if (days) {
        var date = new Date();
        date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
        expires = "; expires=" + date.toGMTString();
    }
    else {
        expires = "";
    }
    document.cookie = name+"="+value+expires+"; path=/";
}

function readCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for(var i=0;i < ca.length;i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') {
            c = c.substring(1,c.length);
        } 
        if (c.indexOf(nameEQ) === 0) {
            return c.substring(nameEQ.length, c.length);
        }
    }
    return null;
}

function eraseCookie(name) {
    createCookie(name,"",-1);
}
