php - How to hide values in hidden fields?

Question

I have a simple form in which I have 3 hidden fields, through which I am passing values to another page.

But I don't want anyone to see it through view page source or Fire Bug. I am working with PHP.

<form action=" " method="post" name="push">
    <input type="hidden" name="publisherid" value="createcoolapps"/>
    <input type="hidden" name="username"value="buzzmo"/>
    <input type="hidden" name="pass" value="Javea0615"/>
    <select name="appid">
        <option value="QRScanner">app1</option>
        <option value="app2">app2</option>
        <option value="app3">app3 </option>
        <option value="app4">app4</option>
    </select > 
    <input type="hidden" name="topics" value=" "/>
    Notification Message:<br />
    <textarea style="width:10; height:10;" name="pushmessage"></textarea><br/>
    <input type="submit" value="Push"/>
</form>

You can't hide anything in HTML. If it's in the code, anyone can see it. If you need to pass values between pages and keep them hidden, then you need to use Sessions.
