How to Correctly Insert Dates from jQuery Datepicker into MySQL Using PHP?

Inserting Date Formats into MySQL Using PHP

When working with the MySQL database, it's essential to format date values correctly during insertion. A common issue is inserting dates in the incorrect format, leading to database errors.

Problem:

You're using the jQuery datepicker, which returns dates in 'MM/DD/YYYY' format. However, MySQL expects dates in specific formats, such as 'YYYY-MM-DD', 'YY-MM-DD', or 'YYYYMMDD'. Inserting dates in the incorrect format will result in '0000-00-00 00 00 00' being inserted.

Solution:

There are several ways to resolve this issue:

• Use the Datepicker's altField and altFormat options: Configure the datepicker to provide dates in a supported format by setting the altField and altFormat options. For example:

<input type="hidden">

• Convert the string using MySQL's STR_TO_DATE() function: Convert the date string received from jQuery into a valid MySQL format using the STR_TO_DATE() function:

INSERT INTO user_date VALUES ('', '$name', STR_TO_DATE('$date', '%m/%d/%Y'))

• Use PHP's DateTime class: Convert the string into a PHP DateTime object and then obtain a suitable formatted string or UNIX timestamp:

$dt = \DateTime::createFromFormat('m/d/Y', $_POST['date']);
$date = $dt->format('Y-m-d'); // Formatted string
$timestamp = $dt->getTimestamp(); // UNIX timestamp

• Manually manipulate the string: Manually split the date string into its components and assemble it in the correct format:

$parts = explode('/', $_POST['date']);
$date = "$parts[2]-$parts[0]-$parts[1]";

Caution:

1. Avoid SQL injection: Ensure you are using prepared statements to prevent SQL injection vulnerabilities.
2. Use the DATE type instead of DATETIME or TIMESTAMP: The DATE type is recommended for storing pure date values without time components.

Additional Notes:

• The mysql_* functions are deprecated in PHP 5.5.0 and should be replaced with the mysqli or PDO_MySQL extensions.
• The STR_TO_DATE() function requires the date_format system variable to be set to the appropriate format for parsing the date string.
