I am trying to validate a birthdate (provided in 3 separate inputs: day [nac_fecha_d], month [nac_fecha_m] and year [nac_fecha_a]), first to see if it's a valid date and then to see if the person is 18 or older. The problem is everytime I add this block of code to my custom validation, my form gets into event loops with no error message displayed. As hard as I look at this I can't find what's causing it. I'm no PHP expert, so any input will be appreciated.

 
  $trimmed_d = trim ($form->data{'nac_fecha_d']));
  $trimmed_m = trim ($form->data{'nac_fecha_m']));
  $trimmed_a = trim ($form->data{'nac_fecha_a']));  

  if ( checkdate($trimmed_m,$trimmed_d,$trimmed_a) )

  {
    //// Calcular edad ///////////////////////////  
    $a_dif = date("Y") - $trimmed_a;
    $m_dif = date("m") - $trimmed_m;
    $d_dif = date("d") - $trimmed_d;

    if (($d_dif < 0) || ($m_dif < 0))
	
    { $a_dif--; }

    if ( $a_dif < 18 )
	
    {
      $form->validation_errors['nac_fecha_a'] = 'Lo sentimos. Tienes que ser mayor de edad para inscribirte. Si escribiste una fecha de nacimiento equivocada, corrígela por favor.';
      $error_count++;
    }
  }

  else
  
  {
    $form->validation_errors['nac_fecha_a'] = 'La fecha es incorrecta. Debes escribir día, mes y año. Ej.: 05-09-1988';
    $error_count++;
  }

P.S. Though I guess it's not relevant, I'm using V4 with Joomla 1.6

Hi dmontpe,

Please try this:

<?php
$error_count = 0;
$d = trim ($form->data['nac_fecha_d']);
$m = trim ($form->data['nac_fecha_m']);
$a = trim ($form->data['nac_fecha_a']);
if ( checkdate($m, $d ,$a) ) { 
  $timestamp_18 = mktime(0, 0, 0, $d, $m, $a + 18);
  if ( $timestamp_18 > mktime() ) {
    $form->validation_errors['nac_fecha_a'] = 'Lo sentimos. Tienes que ser mayor de edad para inscribirte. Si escribiste una fecha de nacimiento equivocada, corrígela por favor.';
    $error_count++;
  }
} else {
  $form->validation_errors['nac_fecha_a'] = 'La fecha es incorrecta. Debes escribir día, mes y año. Ej.: 05-09-1988';
  $error_count++;
}
if ( $error_count ) {
  return false;
}
?>

Thanks, Greyhead. I tried the code and it didn't work either. Just in case, I hadn't added the first and last line(s) (concerning error_count) because the code was just part of a larger whole. I'm really confused because I already have this:

function is_digits($element) { return !preg_match ("/[^0-9]/", $element); }

if ( (is_digits($form->data['nac_fecha_d'])) && (is_digits($form->data['nac_fecha_m'])) && (is_digits($form->data['nac_fecha_a'])) && (strlen($form->data['nac_fecha_a']) == 4) ) { }

else {
  $form->validation_errors['nac_fecha_a'] = 'La fecha es incorrecta. Debes escribir día, mes y año. Ej.: 05-09-1988';
  $error_count++;
}

and it works just fine. But then I even replaced it with this isolated part of your code:

$d = trim ($form->data{'nac_fecha_d']);
$m = trim ($form->data{'nac_fecha_m']);
$a = trim ($form->data{'nac_fecha_a']); 
if ( checkdate($m, $d ,$a) ) { }
else {
  $form->validation_errors['nac_fecha_a'] = 'La fecha es incorrecta. Debes escribir día, mes y año. Ej.: 05-09-1988';
  $error_count++;
}

And it fails the same way: whether the input is valid or not, the form gets reloaded with no error message. (Notice it's the same error message that is defined) I just don't get what's failing.

Could this be a bug?

Hi David,

I built a test form and fixed a few typos ( four bad {s and a $d ) and the code now appears to work OK.

I've updated my previous post with the corrected version.

Thank you so much, Bob. It does work now. I'm sorry I gave up going over the code just too soon.
