Hey everyone, A bit of a puzzle here, dont know if this is a JS problem or PHP or FF or .... just me. (My money is on the last one :p ) Here's what I am trying to do: In a form I have a listbox with the values 1-5, and under the listbox i have a <TD> with the id of "recips" (like so: <TD id='recips"> I have a onChange event linked to the list box and depending on what number the client picks it should dynamically put the number of text boxes there, here is the JS code: ///// ############### Start JS code ############ function change_no_of_recipients() { var nr=document.mainform.no_of_friends.options[document.mainform.no_of_friends.selectedIndex].value;

        if(nr>5){nr=5;} // max number of recipients
    var msg = "";

for (var x = 1; x <= nr; x++) { msg += '<table width="50%" border="0" cellspacing="2" cellpadding="2">' + '<tr>' +

    '<td nowrap="nowrap">'+ x +'. Recipient\'s name:</td>' +
    '<td><input type="text" name="rec_name[]" id="rec_name[]" /></td>' +
    '<td nowrap="nowrap">Recipient\'s email:</td>' +
    '<td><input type="text" name="rec_email[]" id="rec_email[]" /></td>' +

'</tr>' + '<tr>' + '</table>'; }

        document.getElementById('recips').innerHTML=msg;

} ///// ##################### End JS code ################ So far on the page everything is working, but when I click the submit button this is my PHP processing script: <?php print_r($_REQUEST); ?> It shows me everything that has been submitted but NOT any of the above dynamically made boxes values... but get this, it DOES show me all values... in IE7 _not_ in FF (am using 2.0.0.13) Anybody else face anything like this? Is this a bug in FF? Is $_REQUEST wrong to catch this? Dont know what the @#$@ to do... ANY help even a link to a site which can shed a little light would be appreciated. Thanks in advance. /Ryan

Hi Ryan, Since I'm relatively new to PHP I could be off on this, but I'd say yes, $_REQUEST is wrong. I would think you'd want to use $_POST to receive the incoming values from a form.

That would depend on the method that the form is using: GET or POST. I don't think that's the answer. Two things I would suggest: 1. Check that the Javascript is doing what you expect: you *are* using Firebug on Firefox, aren't you? Also the WebDeveloper toolbar plugin is useful - it has a View Generated Source tool which will show you what Firefox thinks your page actually looks like after the JS has run... 2. Check that the TD you are loading with content is actually inside the <FORM> tags - otherwise the inputs won't be included in the request/post variables...
