I'm setting up an auction website using PHP and MySQL. There in the
section where logged in members can put up new auction in a form, I
want to run a form validation where I used if else statements to check
the fileds filled. In the form page there are two radio buttons -
fixed and auction - (only one can be chosen) and depend upon which one
is chosen some text should be inserted in the text fields. For that
I'm using a validation where this nested if else is not working
properly. It checks until some if statements then won't check the rest
of the if statements. The codes below I have reduced to relevant
parts.
names of
radio buttons: groupname - 'rdoAuctionType', with 'fixed',
'auction'
text fields:
when 'fixed' button is selected, text field 'txtFixedPrice'
must be filled
when 'auction' button is selected, text fields
'txtStartPrice' and 'txtIncrement' must be filled
---------------------------------------------------------------------------*------------------------------------------------------------
Here is the code:
auction_formvalidation.php
if(isset($_POST['btnConfirm'])) {
.............
.............
$auctiontype = $_POST['rdoAuctionType'];
$fixedprice = $_POST['txtFixedPrice'];
$startprice = $_POST['txtStartPrice'];
$bidincrement = $_POST['txtIncrement'];
$duration = $_POST['txtDuration'];
...........
if {
.....
}
else if {
......
}
else if(trim($auctiontype) != '') {
if(trim($auctiontype) == 'fixed') {
if(trim($fixedprice) == '') {
$errmsg .= '<li>Please enter the fixed price.</li>';
}
else if(!isNumber($fixedprice)){
$errmsg .= '<li>Fixed price should only contain numbers.</
li>';
}
}
else if(trim($auctiontype) == 'auction'){
if(trim($startprice) == '') {
$errmsg .= '<li>Please enter the start price.</li>';
}
else if(!isNumber($startprice)) {
$errmsg .= '<li>Start price should only contain numbers.</
li>';
}
else if(trim($bidincrement) == '') {
$errmsg .= '<li>Please enter your bid increment.</li>';
}
else if(!isNumber($bidincrement)) {
$errmsg .= '<li>Bid increment should only contain numbers.</
li>';
}
}
}
else if(trim($duration) == '') { <----------------- it doent check
from here ownwards
$errmsg .= '<li>Please enter the duration for the auction.</li>';
}
else if {
.......
}
}
Code of form page:
add_auction.php
<html>

<form name="formRegister" action="add_auction.php" method="post">

I have posted this in some other group, but until now didn't get any
reply. So I thought to put it here too. Am I in the right place? :s
Could somebody help me? I would be thankful :)
