If I understand what you mean, you would like them to go back to the last
page they were on before they came to this page where they might have
clicked a few icons and updated the page?
In my applications where I need to do this, I carry around a variable called
$returnto. Then all of my urls contain '&returnto=' . myGetURI($returnto).
On the page with the clickable icons, just use '&returnto=' . $returnto on
the icons in order to not add the current page into the history.
Then you can have a back button with href=$returnto.
The code below adds the current page to the $returnto variable, preserving
other querystring variable.
function myGetURI($returnto) {
global $QUERY_STRING;
global $SCRIPT_NAME;
if ($returnto=='close') {
$function_ret='close';
} else {
$QS=$QUERY_STRING.'';
$tempURI=$SCRIPT_NAME.($QS!=''?'?'.$QS:'');
if ((strpos($QS,"returnto")==0) && ($returnto!='')) {
$tempURI=hrefargs($tempURI,'returnto',$returnto);
}
$function_ret=rawurlencode($tempURI);
}
return $function_ret;
}
function hrefargs($href,$arg,$val) {
$function_ret =
$href.((strpos($href,'?')>0)?'&':'?').$arg.'='.rawurlencode($val);
return $function_ret;
}
