Re: [PHP] passing variables from forms to the same page repetatively
This function that matt sent to automatically write hidden inputs is
awesome. it works great. I am only using the first function.
It's a great solution.
thanks

I was doing something similar just yesterday. Ended up with a little
function to automatically write hidden inputs 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

be able to use variables created by the first form in the html part of
the last form. What is the best way to do this?
So far, I can only use variables on the next page (form) that is
written out. After that those variables have no value. Is there some
way to submit all variables present and assigned with the submission of
each form? If I make the forms a seperate include file, instead of
having them in-line, how does this change the ways variables are passed

If I understand what you are saying: those variables don't exist until
you SUBMIT the form. You can demonstrate this by looping through and
displaying your POST or GET vars at the beginning of the form and see
what happens when you first open the page, and when it calls itself.
And re-reading, I think what you may want is hidden fields. You want part
one to call part 2, and retain values from part 1, etc? Echo the values
into hidden fields in each step of the process.
INPUT TYPE=hidden NAME=whatever VALUE=?php echo $whatever ?

Re: [PHP] passing variables from forms to the same page repetatively
Yeah, I had thought about using hidden inputs, but hidden inputs are not really hidden. They still exist on the HTML page, and although not visible in the browser, are visible in the code. This may not be cool if you have sensitive information that is passed, also if you have a lot of variables to pass, thats just a lot of hidden inputs to pass. Is there no other way to accomplish this? No built in function? I guess it makes sense that there is not, b/c the form submits the form and only the form variables.

Re: [PHP] passing variables from forms to the same page repetatively
There are a thousand ways to pass data... some are just more kludgy than others =) In addition to using hidden fields You could put the data into a Database You could Write it to a file You could put it in a cookie You could use sessions etc, etc, ad nauseam Two things to point out, however. The first is that using Hidden fields is not really frowned down upon (at least not by anyone I know) and will probably lead to the least convoluted code. The second is that anything passed in a form (unless you are using SSL or something) is already insecure. If you have truly sensitive information you need to be looking into encryption, if not then why sweat the hidden fields?

Re: [PHP] passing variables from forms to the same page repetatively
What about registering some session variables? Sessions use cookies and/or URLs to propagate info across multiple pages. Not really secure, though, but they are easy to use.
