I have an online tutorial build into a web page. It has button next step. If you are on page index.php?abc=123 for instance the code is smart enough to make it index.php?abc=123&step=x
The problem is how to remove step=x from the old url string so that steps don't pile up. index.php?abc=123&step=1&step=2 I'm trying ereg but could use a nudge with the wild card aspect of searching and replacing.
The code below builds the get string.
$stepnum = $_GET["step"];
$laststep=$stepnum-1; $nextstep=$stepnum+1;
$args = $_SERVER["REQUEST_URI"]; if ($_SERVER["argc"]>0) $args.="&"; else $args.="?";
if ($stepnum>1) { echo "<br><a href='$args"; echo "step=1'>step 1</a><br>"; }
if ($laststep>0) { echo "<br><a href='$args"; echo "step=$laststep'>backup 1 step</a><br>"; }
echo "<br><a href='$args"; echo "step=$nextstep'>next step</a><br>";
thx
