Hi all,

I'm trying to display 2 extra input tags if the user selects two options from a six option drop down in a form, so it would look like so:

If option A,B selected = true,

then echo 2 extra inputs,

else

if options C,D,E,F selected = false

then do not display inputs.

By the way I'm a beginner php programmer (need experience) so I coded my form with the php in the spots where need, DW does no display syntax error so I'm guessing is correct but when I preview in browser inputs show when they are not supposed to. Can someone please advice and if possible explain my problem,my code for the form is below:

 

Thanks in acvance

Your code makes little sense. At one place you set $do to the string 'Casa', you later then attempt to check to see if $do is true (the comparison operator is == in php, not =).

 

Anyway, what your trying to do would be best done client side using Javascript, not server side using PHP.

Thanks guys for the help, I used javascript for this and it works like a charm, I know this is the php section but I think it will helpful for other ppl. so here is what I used:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<meta http-equiv="Content-type" content="text/html; charset=utf-8" />
<title>Show/Hide</title>
<script type="text/javascript">
// <![CDATA[
function display(obj,id1,id2,id3,id4,id5) {
txt = obj.options[obj.selectedIndex].value;
document.getElementById(id1).style.display = 'none';
document.getElementById(id2).style.display = 'none';
document.getElementById(id3).style.display = 'none';
document.getElementById(id4).style.display = 'none';
document.getElementById(id5).style.display = 'none';
if ( txt.match(id1) ) {
document.getElementById(id1).style.display = 'block';
}
if ( txt.match(id2) ) {
document.getElementById(id2).style.display = 'block';
}
if ( txt.match(id3) ) {
document.getElementById(id3).style.display = 'block';
}
if ( txt.match(id4) ) {
document.getElementById(id4).style.display = 'block';
}
if ( txt.match(id5) ) {
document.getElementById(id5).style.display = 'block';
}
}
// ]]>
</script>
<script>
// This adds 'placeholder' to the items listed in the jQuery .support object.
jQuery(function() {
jQuery.support.placeholder = false;
test = document.createElement('input');
if('placeholder' in test) jQuery.support.placeholder = true;
});
// This adds placeholder support to browsers that wouldn't otherwise support it.
$(function() {
if(!$.support.placeholder) {
var active = document.activeElement;
$(':text').focus(function () {
if ($(this).attr('placeholder') != '' && $(this).val() == $(this).attr('placeholder')) {
$(this).val('').removeClass('hasPlaceholder');
}
}).blur(function () {
if ($(this).attr('placeholder') != '' && ($(this).val() == '' || $(this).val() == $(this).attr('placeholder'))) {
$(this).val($(this).attr('placeholder')).addClass('hasPlaceholder');
}
});
$(':text').blur();
$(active).focus();
$('form:eq(0)').submit(function () {
$(':text.hasPlaceholder').val('');
});
}
});
