checkdate() if statement help please

[dadamssg]

im trying to check if a birthday exists and then to see if the birthday makes them older than 13...ive never used checkdate() before so yeah. i'm getting this error on the very first line

 

Parse error: syntax error, unexpected '{', expecting ')' on line 40

 

if(checkdate({$_POST['bmonth']}, {$_POST['bday']},{$_POST['byear']}))
    ///check to see if bday is valid and older than 13
{ 
   if(strtotime({$_POST['bmonth']}, {$_POST['bday']},{$_POST['byear']}) > 12299040000)
       	{
    $messages[]= "You must be at least 13 years of age to register.";
    }
}
else
///date is not valid
    {
$messages[]= "This date doesn't exist.";
}

<?php
if(checkdate($_POST['bmonth'], $_POST['bday'],$_POST['byear']))
    ///check to see if bday is valid and older than 13
{ 
   if(strtotime($_POST['bmonth'], $_POST['bday'],$_POST['byear']) > 12299040000)
        {
    $messages= "You must be at least 13 years of age to register.";
    }
}
else
///date is not valid
    {
$messages= "This date doesn't exist.";
}
?>

Improper use of "}" and "{"...

You need to make these values integers; as of current they are strings because they came from $_POST. Use the below example for each $_POST:

 <?php
$bmonth=intval($_POST['bmonth']);
?>

[dadamssg]

same result...i don't think i have the checkdate part set up right,

 

 

//make date values integars 

  $bmonth = intval($_POST['bmonth']);
  $bday = intval($_POST['bday']);
  $byear = intval($_POST['byear']);
  
  
if(checkdate($bmonth, $bday, $byear))
    ///check to see if bday is valid and older than 13
{ 
   if(strtotime($bmonth, $bday, $byear) > 12299040000)
       	{
    $messages[]= "You must be at least 13 years of age to register.";
    }
}
else
///date is not valid
    {
$messages[]= "This date does not exist.";
}

[premiso]

if(strtotime("{$byear}-{$bmonth}-{$bday}") > 12299040000)

 

Or

 

if(mktime(0,0,0,$bmonth, $bday, $byear) > 12299040000)

 

Both should work, if not the second one should definately work. But why are you checking against a hard coded time code? That should be dynamic as well.

i tried this but same result...because 12299040000 is thirteen years old in seconds.

 

//make date values integars 

  $bmonth = intval($_POST['bmonth']);
  $bday = intval($_POST['bday']);
  $byear = intval($_POST['byear']);
  
$today = gmmktime(0,0,0,date('n'),date('j'),date('Y')); 
  $userbday = gmmktime(0,0,0,$bmonth,$bday,$byear);
  
  $difference = $today - $userbday;
  
if(checkdate($bmonth, $bday, $byear))
    ///check to see if bday is valid and older than 13
{ 
   if($difference > 12299040000)
       	{
    $messages[]= "You must be at least 13 years of age to register.";
    }
}
else
///date is not valid
    {
$messages[]= "This date does not exist.";
}
