html forms resubmitting

norpel

hi,
I have a html page with several forms on it. As the user moves through, filling out fields the form submits and recalls the page, passing through some GET variables.

is there any way to make the page call itself (with the variables that had been previously passed to it), also adding on some new ones.

eg form1 submits fields var1 & var2

mypage.php?var1=1&var2=1

then some other form (form2) submits (adding a field var3)

mypage?var1=1&var2=1&var3=dog

currently I need to add hidden fields var1=$GET['var1'], var2=$GET['var2'] in form 2 while submitting to getenv('SCRIPT_NAME') to get this to work

is there an easier way?

or even is there a way to read all the passed variables (however many there might be, or whatever they might be) into an array?

thanks,
norpel

You don't need to "read all the passed variables into an array". PHP does that already. That's what the $_GET array is.

If you want to create hidden form variables for all of the submitted data, you could do something like this:

foreach ($_GET as $name => $value) {
    echo '<input type="hidden" name="'.
    htmlentities($name).'" "value="'.
    htmlentities($value).'">';
}

Be aware that there are often limits on how much data you can pass with GET. That limit varies depending on web server, web browser, and whatever proxies might be in between. Use POST if you need to send a lot of data.

You may want to use sessions instead. See the [man]session_start[/man] manual page for an example.

perfect... thank-you

I thought it should be easy, but couldn't figure out how.

for anyone else who's going to use the code above the " before value should be left out...

so the code is....

 foreach ($_GET as $name => $value) {
         echo '<input type="hidden" name="'.
         htmlentities($name).'" value="'.
         htmlentities($value).'">';                      

}

it took me a few goes to figure out what was wrong & why my variables weren't getting passed
