Subject: Re: [PHP] passing variables from forms to the same page
repetatively
Date: Tue, 17 Jul 2001 11:23:11 +0100
I was doing something similar just yesterday. Ended up with a little
function to automatically write hidden <input>s for every variable that's
submitted, whether posted or thru the url. Goes like this...
// put this somewhere in your form
<?php print get_param_inputs(); ?>
// the function itself
function get_param_inputs() {
global $HTTP_GET_VARS, $HTTP_POST_VARS;
$ret_str = "";
$params = array_merge($HTTP_GET_VARS, $HTTP_POST_VARS);
foreach ($params as $k=>$v) {
if (is_array($v)) {
foreach($v as $kk=>$vv) {
$ret_str .= '<input type="hidden" name="'."$k[$kk]".'
value="'.$vv.'">';
}
}
else {
$ret_str .= '<input type="hidden" name="'.$k.'" value="'.$v.'">';
}
}
return $ret_str;
}
I also needed to append the variables to links on the same page (for page 1,
page 2, page 3... type thing) so did this:
<a href="<?php print $PHP_SELF.get_param_query() ?>">link</a>
function get_param_query() {
global $HTTP_GET_VARS, $HTTP_POST_VARS;
$ret_str = "";
$params = array_merge($HTTP_GET_VARS, $HTTP_POST_VARS);
$j = "?";
foreach ($params as $k=>$v) {
if (is_array($v)) {
foreach($v as $kk=>$vv) {
$ret_str .= $j.urlencode("$k[$kk]=$vv");
$j = "&";
}
}
else {
$ret_str .= $j.urlencode("$k=$v");
$j = "&";
}
}
return $ret_str;
}
Won't work if you're nesting arrays within arrays, but I'm not a recursive
type. Hope it helps,
Matt
