Date is not saving to database - php

Question

I'm creating an appointment plugin, in that for already members and new members are there. in already member area the date entry is not entring into db. but when displaying the variale contains the date. i'm have been checking this from morning but didn't get what is the error. my code is:
$source = mysql_real_escape_string(trim($_POST['apdatetime']));
$datetime = explode(',', $source);
$dates = $datetime[0];
$app_time = $datetime[1];
if($app_time < 12){
$app_session = 'am';
}
else{
$app_session ='pm';
}
$splitdatet = explode('/', $dates);
$yyear = $splitdatet[2];
$mmonth = $splitdatet[1];
$ddate = $splitdatet[0];
$app_date = $yyear . "-" . $mmonth . "-" . $ddate;
if ($_POST['isnewpatient'] == "false") {
//$cSql = "select * from " . WP_contact . " where appointments_c_patientid='" . trim($_POST['ptntid']) . "' ";
$cSql = "select * from " . WP_eemail_TABLE_SUB . " where eemail_patient_id='" . trim($_POST['ptntid']) . "' ";
$data = $wpdb->get_results($cSql);
if (empty($data )) {
$err = 1;
echo "<div id='message' class='aerror'>No such patient ID exists....</div>";
} else {
#$mobile = htmlspecialchars(stripslashes($data[0]->eemail_mobile_sub));
#$email = htmlspecialchars(stripslashes($data[0]->eemail_email_sub));
#$name = htmlspecialchars(stripslashes($data[0]->eemail_name_sub));
$sqlss = "insert into " . WP_Appointments .
" (`appointments_patient_id`,`appointments_date`,`appointments_time`,`appointments_session`,`appointments_reg_date`) VALUES ('" .
mysql_real_escape_string(trim($_POST['ptntid'])) . "','" .
$app_date . "','" .
$app_time . "','" .
$app_session . "',CURRENT_TIMESTAMP() )";
$dd=$wpdb->get_results($sqlss);
var_dump($dd);
echo 'Date:'.$app_date;
// return $suc;
echo "<div id='message' class='asuccess' >Request has been sent for appointment</div>";
}
}
The output of the var_dump is array[0] and $app_date is Date:2014-10-22
The db entry is
appointments_id :393
appointments_patient_id : 9999999999
appointments_date : 0000-00-00
appointments_time : 9:00
appointments_session : am
appointments_reg_date : 2014-09-25 14:21:35
could anyone please point out the mistake in the code if any??

You should convert your string into date object like this:
$app_date = date('Y-m-d',strtotime($app_date));
