freelance84 Posted November 21, 2011 Share Posted November 21, 2011 a Username javascript variable Do you mean a javascript variable which you have names Username? Either write a hidden field to you page with js so is submitted on form submission or/ use ajax Link to comment https://forums.phpfreaks.com/topic/251541-pass-a-username-javascript-variable-to-next-page-as-hidden/#findComment-1289956 Share on other sites More sharing options...
sungpeng Posted November 21, 2011 Author Share Posted November 21, 2011 yes it is inside Username and must be called out by "id=username" Link to comment https://forums.phpfreaks.com/topic/251541-pass-a-username-javascript-variable-to-next-page-as-hidden/#findComment-1289960 Share on other sites More sharing options...
Adam Posted November 21, 2011 Share Posted November 21, 2011 The data sent in a POST method form *is* hidden from sight. It's not difficult to retrieve of course, but then again no client-side data is. If your system is vulnerable when somebody changes the value, then you need to rethink your server side security, not the client-side.

Adam Posted November 21, 2011 Share Posted November 21, 2011 Whoops, misread your post. When code this <input id="Username" type="hidden" name="date2" /> Data fail to pass over You're not actually passing any data across..?

freelance84 Posted November 21, 2011 Share Posted November 21, 2011 This really doesn't sound like a php question. Are you saying the variable is being created by some js function on the page after the client has loaded said html page, after which you wish to place said variable into "<input id="Username" type="hidden" name="date2" />" ? document.getElementById('Username').value= Username; Link to comment https://forums.phpfreaks.com/topic/251541-pass-a-username-javascript-variable-to-next-page-as-hidden/#findComment-1289990 Share on other sites More sharing options...

freelance84 Posted November 21, 2011 Share Posted November 21, 2011 Sorry mate, really not sure i know what your trying to get at... From the OP: <input id="Username" type="hidden" name="date2" /> The hidden form element above is being assigned a value from a JavaScript variable which your server is receiving when the user submits the form. You are now asking for another way to submit the data from the client to the server which is safe from tampering... Without seeing your whole process start to end this is a pretty hard question to answer, however if you can see no other way of your server receiving the data (ie the only way is from the client) then i would guess your answer is no.

freelance84 Posted November 21, 2011 Share Posted November 21, 2011 If you want to send the js variable 'Username' to php without submitting your form (which it sounds like you do) then you need to use AJAX. Try searching the basics of AJAX if you don't know about AJAX.

freelance84 Posted November 21, 2011 Share Posted November 21, 2011 I'm not going to write it for you mate... have a bash your self and post a specific problem if you hit one. Otherwise post it as a job in the freelance section. Or, if you have already hit a specific problem then be more specific in your question.
