Php regex date validation

Question

I\'m trying to validate a date input by the use of regex.

if(!preg_match(\"/^[0-9]{4}\\/[0-9]{2}\\/[0-9]{2}$/\", $_POST[\'variant\'][\'sales_start\'])) { 
           


        

Answer 1

You're separating the date with dashes and the regex is looking for slashes?

Try

if ( !preg_match( "/^[0-9]{4}-[0-9]{2}-[0-9]{2}$/", $_POST['variant']['sales_start'] ) )
{ 
    echo "invalid";
}
