Question

I am trying to do something like htis

foreach ($_POST as $key => $value)
    {
    $newNode->field_$key['und'][0]['value'] = $value;
    }

php complains of Parse error: syntax error, unexpected T_VARIABLE

I tried

foreach ($_POST as $key => $value)
    {
    $newNode->field_{$key}['und'][0]['value'] = $value;
    }

But then key is output as an array. Not sure why.

Any tips?

Answer 1

The correct notation would be

$newNode->{"field_".$key}

that should work. But as @Furicane says, arrays are vastly better for this.
