Modifying dates using custom methods

Some WordPress fields require dates to be entered in a specific format, you can easily change the format of a date using ImportWP’s custom methods, which allows you to create a function/method in your themes function file or via a plugin, which will process the data before before it is imported.

Add the following code snippet to your website:

function iwpe01_format_date($input = '', $output_format = 'd/m/Y', $input_format = 'date')

    switch ($input_format) {
        case 'date':
            $time = strtotime($input);
        case 'timestamp':
            $time = $input;

    if (intval($time) == 0) {
        return '';

    return date($output_format, $time);

Then when editing your importer on the “Template Fields” step, you can use the custom method, each argument withing “” can be replaced with data from your importer e.g. csv: {0} or xml: {/date}

Example returning the default date format:

Example changing the returned date format:

[iwpe01_format_date("2021-06-04T18:59:59.999Z", "d-m-Y")]

Example converting a timestamp into a date format:

[iwpe01_format_date("1622833199", "d-m-Y", "timestamp")]
