validation show if not showing

Hi, Few quick questioins:
1. my validations on the attached page are stopping the form working fine if not correctly filled, but the "show if" error doesnt trigger and show - why so? its set to correct page and supposedly triggering on ANY failure?

2. Secondly - I notice on my test page that when the validation stops the form submitting and reloads the page it knocks out all the entered data - thats gonna be frustrating for users - is there a (simple :) ) way of having it hold on to that data and showing the SHOW IF validation?

3. On some pages (esp application8.php i get the following message appear sometines (tho it doesnt seem to affect function) - how do i rid of it?

Deprecated: mysql_pconnect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in /home/hp3-linc2-nfs2-y/307/134307/user/htdocs/Connections/fhcdbase.php on line 9

4. Lastly - I have some radio check boxes for yes/no (1,0) answers - i presume if they check YES, that'll put a 1 in the YES database field but nothing in the NO database field - how would i set up a validation that says _allow if EITHER YES checked OR NO checked but not both required)

1) You have 5 different server validations server behaviors applied on the page. You should only have one and add 5 different validation rows.

The final code should look like:

<?php 

if ($_SERVER["REQUEST_METHOD"] == "POST")  {

  $WAFV_Redirect = "";

  $_SESSION['WAVT_application1_334_Errors'] = "";

  if ($WAFV_Redirect == "")  {

    $WAFV_Redirect = $_SERVER["PHP_SELF"];

  }

  $WAFV_Errors = "";

  $WAFV_Errors .= WAValidateRQ(((isset($_POST["DD"]))?$_POST["DD"]:"") . "",false,1);

  $WAFV_Errors .= WAValidateRQ(((isset($_POST["MM"]))?$_POST["MM"]:"") . "",false,2);

  $WAFV_Errors .= WAValidateRQ(((isset($_POST["YYYY"]))?$_POST["YYYY"]:"") . "",false,3);

  $WAFV_Errors .= WAValidateNM(((isset($_POST["age"]))?$_POST["age"]:"") . "",0,100,0,",.",true,4);

  $WAFV_Errors .= WAValidateRQ(((isset($_POST["sex"]))?$_POST["sex"]:"") . "",false,5);



  if ($WAFV_Errors != "")  {

    PostResult($WAFV_Redirect,$WAFV_Errors,"application1_334");

  }

}

?>

2) Set the values of the form elements from the Bindings panel where it says "Validated Fields". That will repopulate them with the previously set value.

3) Update your php.ini file and turn off 'deprecated' messages.

4) It isn't necessary to add validation to radio buttons. Just set one or the other to checked by default and then by their nature one or the other will have to be selected at all times. (The only way you can uncheck a radio button is by checking another)
