If DateTime Object Is Null

Question

I am returning some search results after form submit. All is working fine, until I get to a field that is SMALLDATETIME and allows NULL. At least one of the returned rows ha

Answer 1

Try this,

<td class='col45'>".date_format(new DateTime( $search_results_option->HardwareAssetLastUpdateTime ),"d/m/Y H:i")."</td>
<td class='col46'>".$search_results_option->HardwareAssetLastUpdatedByName."</td>
<td class='col47'>".date_format(new DateTime( $search_results_option->HardwareAssetLastDiscoveryScanDate ),"d/m/Y H:i")."</td></tr>";

date_format() need the date to be in DateTime format when supplied, you are passing a string.

The other thing may be that $search_results_option is empty

For NULL values:

( $search_results_option->HardwareAssetLastDiscoveryScanDate != null ? date_format(new DateTime( $search_results_option->HardwareAssetLastDiscoveryScanDate ),"d/m/Y H:i") : '' )

This will check for a null value, if it is not null it will display the formatted datetime, els eit will display nothing

Answer 2

<td>".(
   is_null($search_results_option->HardwareAssetLastDiscoveryScanDate) ? '' : 
       date_format($search_results_option->HardwareAssetLastDiscoveryScanDate,
        "d/m/Y H:i")
    )
 ."</td>";
