TYPO3-TCA-日期时间格式

Question

Typo3 6.2, working on my personal extension. I'm using a flexform with this TCA :

'eventdate' => array(
    'exclude' => 1,
    'label' => 'Date of event :',
    'config' => array(
        'type' => 'input',
        'size' => 30,
        'eval'     => 'datetime',
        'checkbox' => '0',
        'default'  => time(),
    ),
),

... and my SQL field is a DATETIME, sample from my ext_tables.sql :

CREATE TABLE xxxxxxx
(
    eventdate DATETIME NOT NULL,
);

Problem : when saving, the generated field format by Typo3 is hh:mm:ss dd:mm:yyyy but in my SQL table the datetime format is yyyy-mm-dd hh:mm:ss , then it makes an error when user try to save in the backend :

1: These fields are not properly updated in database: (eventdate) Probably value mismatch with fieldtype.

How to resolve this issue ?

Answer 1

I think int DATA TYPE is the best way to store DATE in tstamp format in DB.

You need to define eventdate DATA TYPE like below

CREATE TABLE xxxxxxx
(
    eventdate int(11) unsigned DEFAULT '0' NOT NULL,
);

Answer 2

The TCA configuration of the original question misses the dbType property which instructs TYPO3 during saving data in DataHandler to use a different time format (the default format is unix timestamp which is normalized to UTC).

See https://docs.typo3.org/typo3cms/TCAReference/7.6/Reference/Columns/Input/#dbtype for details (the documentation is for TYPO3 7.6 but worked since TYPO3 6.0 as well).

ext_tables.sql

CREATE TABLE tx_myextension_xxxxxxx (
   eventdate DATETIME default NULL
)

TCA field configuration

'eventdate' => array(
    'exclude' => 1,
    'label' => 'Date of event:',
    'config' => array(
        'type' => 'input',
        'size' => 30,
        'eval'     => 'datetime',
        'dbType'   => 'datetime',
        'default'  => date('Y-m-d H:i:s'),
    ),
),

• removed checkbox which is superfluous for type input
• adjusted default value to date('Ymd H:i:s')
• added dbType property

Side note for TYPO3 v8

See https://docs.typo3.org/typo3cms/TCAReference/8.7/ColumnsConfig/Type/Input.html#rendertype-inputdatetime which shows the new render type for datetime values that can be used in TYPO3 v8.
