faking a post

[Anon]

Hi,

I'm working on a submittion form for personal data. Part of the form are mobile numbers - when choosing a country the possible prefixes that're available in that country have to change - I do this by reloading the page using javascript (window.location.href) and then use HTTP_GET_VARS (page.php?country="BE" for example), the problem with this solution is that all information that the user already entered is lost. How can I, on reload, keep all the information entered already (name, age, ...). I don't want to create a long url with all the information in it and use HTTP_GET_VARS. Is possible to "fake" a POST or keep the current values after the reload.

Anyone an idea ?

Thanks,
Frederik.

Gidday Fredo,
I don't call it faking...
Scripts like this are my standard for form processing. Everything to do with the form is contained within the script (input, validation, update etc). I control the
the script processing with the $mode variable.

<<script page1.php>>

<form name="mainform" action="page1.php?mode=A" method=post onSubmit="return javascript_function(this);">

<br>Fullname:<input type=text size=20 name=fullname value="<? echo "$fullname" ?>">
...etc
</form>

You can pass a variable if you set:
<INPUT TYPE=hidden name=my_var value="test">

When you post the form $my_var would be set.

If you are using PHP4, I would consider looking into sessions. Using hidden fields to pass variables between forms is horrendous.. believe me, I've tried it 😉

Ron,

Thanks for the reaction, the problem I have is that I don't do a reload using the POST method but in the javascript,

<select size="1" name="NEC_COUNTRY" onChange="reloadPage(this)">
<option value="BE"<? if(isset($COUNTRY) && $COUNTRY=="BE")) { echo " Selected"; } ?>>België</option>
<option value="NL"<? if(isset($COUNTRY) && $COUNTRY=="NL")) { echo " Selected"; } ? >>Nederland</option>
</select>

function reloadPage()
{
var url = "/neck/neck.php?country=" + document.forms[0].NEC_COUNTRY.value;
window.location.href = url;
}

So I reload the page when country changes, because then the form itself has to change - and the information that stays the same and is already filled in has to stay.

Hope this makes sense. Thanks for the reaction, I'll try some things with it.

P.

Using PHP4 indeed. I'll try some sessions magic. Been reading on it this afternoon.

Thanks.

All,

I found a solution, and it's pretty "simple", I combined PHP4 sessions with this simple JavaScript :

function reloadPage() {
document.forms[0].submit();
}

This way I'm able to catch the POSTED values, keep them in the session and change the fields in the input form.

Sweet!
