How to Properly Insert Dates from a jQuery Datepicker into a MySQL Database?

PHP mysql insert date format

When using a jQuery datepicker with a format of 'MM/DD/YYYY' to insert dates into a MySQL database, you may encounter errors with the inserted date being stored as '0000-00-00 00:00:00'. This issue arises because the 'MM/DD/YYYY' format is not recognized as a valid date literal by MySQL.

According to the MySQL documentation on Date and Time Literals, MySQL recognizes DATE values in the following formats:

• 'YYYY-MM-DD' or 'YY-MM-DD' (with or without delimiters like '/', '-', or '.')
• 'YYYYMMDD' or 'YYMMDD' (without delimiters)
• Numbers in YYYYMMDD or YYMMDD format, if they make sense as dates

To resolve this issue, you can explore the following options:

1. Use PHP's DateTime object to convert the date:

Create a DateTime object from the jQuery datepicker string:

$date = \DateTime::createFromFormat('m/d/Y', $_POST['date']);

Then, format the date into a supported format:

$date_string = $dt->format('Y-m-d');

2. Use MySQL's STR_TO_DATE() function:

Convert the jQuery datepicker string to a MySQL-compatible format using the STR_TO_DATE() function:

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

3. Manually manipulate the string:

Split the jQuery datepicker string into parts for month, day, and year, then create a MySQL-compatible string:

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

4. Configure the jQuery datepicker:

Configure the datepicker to output dates in a supported format using the dateFormat or altField altFormat options:

$( "selector" ).datepicker({
    dateFormat: "yyyy-mm-dd"
});

or

$( "selector" ).datepicker({
    altField: "#actualDate"
    altFormat: "yyyy-mm-dd"
});

Caution:

It's important to protect against SQL injection by using prepared statements. Additionally, consider using the DATE data type in MySQL for storing dates, as it is designed specifically for this purpose.
