Web表单字段数据未传递给PHP

Question

I'm learning, trying to create a simple web form, validate the form data, and pass the data to a php file.

After all of the field values are validated, they are not being passed to the php file.

<form action="/xxxxx.php" method="post" name="registration" onsubmit="return formValidation();">

I've change the form name to anything else...

<form action="/xxxxx.php" method="post" name="anythingelse" onsubmit="return formValidation();">

...the form works (without validation) and the field values are being passed to the php file. I'm receiving the completed form, so I know without validation the web form is working correctly.

So it would appear as though there is something wrong with the validation, IE the function(s) are returning false even after all functions have passed validation and presumably returned true.

Or something else is wrong. I don't understand what's wrong? I'd appreciate any help.

Here's the code.

    <script type="text/javascript">
        function formValidation() {
            var uname = document.registration.username;
            var uadd = document.registration.city;
            var ucountry = document.registration.country;
            var uzip = document.registration.zip;
            var uemail = document.registration.email;
            var uphone = document.registration.phone;
            {
                if (allLetter(uname)) {
                    if (alphanumeric(uadd)) {
                        if (countryselect(ucountry)) {
                            if (allnumeric(uzip)) {
                                if (ValidateEmail(uemail)) {
                                    if (validatePhone(uphone)) {
                                    }
                                }
                            }
                        }
                    }
                }
            }
            return false;

        }

        function validatePhone(uphone) {
            var letters = /^[0-9a-zA-Z-]+$/;
            if (uphone.value.match(letters)) {
                return true;

Answer 1

Your main if statements are contained within random opening and closing braces.

Try removing those random braces, adding return true; inside of your last nested if statement, and containing the return false; within an elseif after the closing braces of the if statements

EDIT:

if (allLetter(uname)) {
    if (alphanumeric(uadd)) {
       if (countryselect(ucountry)) {
        if (allnumeric(uzip)) {
            if (ValidateEmail(uemail)) {
                if (validatePhone(uphone)) {
                    return true;
                }
                else {
                    return false;
                }
            }
            else {
                return false;
            }
        }
        else {
            return false;
        }
    }
    else {
        return false;
    }
}
else {
    return false;
}
}
else {
return false;
}

There are much, much better ways of doing this, but without changing what you've already got too much, try the above.
