Date Not Saving in Mysql from Php Registration Form

Question

I am having trouble saving the date of birth in Mysql Db from Php registration form, what am I doing wrong?

1. Check.php

   $month = $_POST[\'month\'];

Answer 1

You should

• fetch the correct POST-vars!!!!
• use the dot sign for string concaternation
• do a correct quotation
• take care of cases in varnames ($day is not $Day)
• dont put the unfiltered $_GET or $_POST vars into a query string
• dont use mysql_ functions, they are deprecated

this query should do what you want without errors:

$month = $_POST['Birthday_Month']; 
$day = $_POST['Birthday_day']; 
$year = $_POST['Birthday_Year']; 

$date = $year . "-" . $month . "-" . $day;

$query = "INSERT INTO users (FirstName,LastName,Phone,DOB) VALUES ( '" . $FirstName . "','". $LastName . "','" . $Phone . "','" . $date . "')";

mysql_query($query) or die(mysql_error());

EDIT : I saw that you try to fetch the wrong POST-vars! You fetched $_POST['day'] but you need to fetch $_POST['Birthday_day'] which is the name of your select-field
