IP address only saves sometimes

Copy linkTweet thisAlerts:
Oct 24.2005

I have a form where I need to know a persons ip address, and it also displays for them.

for the function i have (in the body):
var ipad = ‘<!–#echo var=”REMOTE_ADDR”–>’
function ipval() {
document.emailform.ip.value=ipad;
}

and then in the form I have:
<input name=”ip” type=text readonly=”true”>

and when I get the form submissions, only about half the time do I get the IP address. is this incorrect or what’s the deal, anyone know?

@MstrBobOct 24.2005 — Why rely on Javscript? Not everyone has javascript enabled. Why not echo it directly?

[code=html]
<input name="ip" type="text" value="<!--#echo var="REMOTE_ADDR"-->" readonly="true">
[/code]

for real? can I use it as is, or do I have to change the " 's to ' 's ?

@UltimaterOct 24.2005 — Even that method is flawed because the user can use a bookmarklet.
<i>
</i>javascript:void(function(){var e=document.getElementsByName("ip")[0];e.value="99.99.99.99";}())


You'd best go server side so the user can't mess with you. PHP is a good choice.

The server side include
value="&lt;!--#echo var="REMOTE_ADDR"--&gt;" works as expected, no need to change all the double quotes into single. It works because each instance of
&lt;!--#echo var="REMOTE_ADDR"--&gt; on the server is replaced with the user's IP address and by the time it reaches the client, for example, it would read:
value="24.55.33.24"

So there is no issue of having double quotes nested-within double quotes in the HTML.

I understand I think...

Is that clip right there what I need? what is that syntax?


edit: also I can't use php because Im using yahoo's cheapest hosting, that doesn't allow php. what's the best javascript or html version?

@UltimaterOct 24.2005 — Can't expect security without some money. Get yourself a domain, you won't regret it. Otherwise, you can use the code MstrBob gave you. The Bookmarklet I gave you is something that any user can type in their address bar to mess with your site.

For example, this bookmarklet will turn my Name "Ultimater" into bold italic text (of this post):
<i>
</i>javascript:void(function(){var e=document.getElementById("postmenu_452913");e.getElementsByTagName("a")[0].innerHTML="&lt;Strong&gt;&lt;i&gt;Ultimater&lt;/i&gt;&lt;/strong&gt;"}())

Oh. look at that, I'm an Administrator now, baby! ?

Success!
