[SOLVED] Birthdate form validation

[Uzm]

Hey!

 

Yesterday i've met a little problem with form validation for birthdate entries that my users enter on my registration page, so i'm asking for a little assistance from you guys.

 

I have three forms on my registration page: select-menu named "birth_date_year", select-menu "birth_date_month" and "birth_date_day".

 

What i want to decline submissions that HAVE selected a value from "birth_date_year", but NOT "birth_date_month" and/or "birth_date_day", or in other way.

 

I've tried with operators, but it seems not to work. Anyone could help me with this? Thanks!

I'm not great with php, but my instinct would be to go with staggered if statements, i.e:

 

if (condition){

  if (condition){

      if (condition){

        code;

      }

  }

}

So basically you want to make sure they have supplied a complete birthday? If you are using selects, then I will assume your first option looks something like this.

[tt]<option value="none">Please Select Day/Month/Year</option>

 

<?php

if ($birth_date_year == 'none' || $birth_date_month == 'none' || $birth_date_day == 'none'){
   echo "ERROR, you didn't fill out a complete birthday";
} else {
   //they supplied all 3 fields, continue
}

?>

pocobueno1388: Thanks for a nice solution, but that wasn't really what i was searching for.

 

I'll try to explain a little closer. Loads of users that registrate themselves on that page, only choose their birthdate month and day, but not YEAR. So, what i want to do is to check, IF year, month OR day has been choosed - but not not the complete birthdate-forms (year/month/day) - for instance if user chooses only his year of birthdate, but doesn't choose day or month of birthdate - user will receive an error.

 

Also, i want to give a apportunity to users not to select their birthdate. So that's really the problem itself.

I am still unclear here.

 

Birthday is optional as a whole, but if they verify the b-day it has to contain specific pieces of the b-day string?? is this pretty close?

All right. Let say, that we have 3 SELECT-menus. First is named "1", second "2", and third "3".

User has to choose values from ALL select-menus. But instead of choosing ALL of them, user only chooses SELECT-menu "1", and doesn't choose anything from second and third menu.

I want to deny those kinds of submits. If user chooses something from first menu, then he/she HAS to choose a value from second and third menu aswell.

<?php

if ($birth_date_year != 'none' || $birth_date_month != 'none' || $birth_date_day != 'none'){
// at least one item has been selected, so lets see if they all have been selected

  if ($birth_date_year == 'none' || $birth_date_month == 'none' || $birth_date_day == 'none'){
   //at least one is empty so give an error
     echo "ERROR, you didn't fill out a complete birthday";
  } else {
     //they supplied all 3 fields, continue
  }

}

?>

 

Is this kinda what your looking for?? If at least one is selected, then make sure all of em are selected, otherwise none have been selected, so skip it.

 

Hope it helps
