BACK button/link?

paulpage

Ok, this is probably a simple thing to do but since I'm self-taught on PHP I haven;t got a clue where to begin.

What I want is a code snippet that I can place on my pages that'll generate a back button or link so that the user can return to the previous page they were on.

Hi,

There is a javascript around which can do it through ..history, -2. Do a little search in the web on this,

Also you could work with <a href="<echo $_SERVER[HTTP_REFERER] ;?>"

Yes, the javascript is as follows:

echo "<script language='javascript'>";
echo "document.write('<a href='Javascript: history.go(-1)'>Back</a>')";
echo "</script>";

That was writen off the top of my head, so it might not work withought a few minor changes.

Hmm, well I've tried the HTTP_REFERER to no avail (and a variation getenv), both bring up no values when I put them into the script.

As for the javascript, it's got a bug somewhere (missing ')' according to IE 5.5 and I don't know javascript to fix it. Any other suggestions?

It's not missing a ). The only thing I can think of is there is a space between java and script. If that doesn't work, then just all javascript, and pull it out of your php.
