I am trying to insert data into a MySql database with the query below.
MySql
$sqlQuery = "insert into abc set a='$var1', b=STR_TO_DATE('$b', '%d/%m/%Y')"
I get this error
Incorrect datetime value: '' for function str_to_date()
str_to_date()
How can I default both a and b to NULL when the variable values are missing.
a
b
NULL
Set default value of these columns in your database as NULL so when these values is missing then NULL with automatically saved as default.
Don't Give mysql to change date format. Do it by your PHP code.
$a = !empty($_POST['var1']) ? $_POST['var1'] : null; $b = !empty($_POST['var2']) ? date('d/m/Y', strtotime($_POST['var2'])) : null; $sqlQuery = "Insert into abc(a,b) values('$a','$b')";
