Hello Jérôme,
I import some data in an ezmatrix datatype. But if the ezmatrix is empty in the new import, the old value stay... I tried
$content->fields->dates_ouverture = " ";
but it creates an empty line in my ezmatrix field (and in my website it display some empty data...)
Do you know how to owerite the value of a ezmatrix field ???
Thank you

Hi Solène and sorry for the late reply...
This is due to how eZMatrix datatype handles strings input.
kernel/classes/datatypes/ezmatrix/ezmatrixtype.php
function fromString( $contentObjectAttribute, $string )
{
if ( $string != '' )
{
$matrix = $contentObjectAttribute->attribute( 'content' );
$matrixRowsList = eZStringUtils::explodeStr( $string, "&" );
$cells = array();
$matrix->Matrix['rows']['sequential'] = array();
$matrix->NumRows = 0;
foreach( $matrixRowsList as $key => $value )
{
$newCells = eZStringUtils::explodeStr( $value, '|' );
$matrixArray[] = $newCells;
$cells = array_merge( $cells, $newCells );
$newRow['columns'] = $newCells;
$newRow['identifier'] = 'row_' . ( $matrix->NumRows + 1 );
$newRow['name'] = 'Row_' . ( $matrix->NumRows + 1 );
$matrix->NumRows++;
$matrix->Matrix['rows']['sequential'][] = $newRow;
}
$matrix->Cells = $cells;
}
return true;
}
Unfortunately, this implementation forces you to always have a line :-(.
Maybe you should open an issue in eZPublish issue tracker and make a pull request ? ;-)
