Saving several checkbox inputs as an array?

Question

Ive got whole bunch of checkbox inputs which all have same name attribute. I want to save their values (1 if checked, also 0 if not because order matters, I need to output them in right order) as an array which is not going as expected.

<input type="checkbox" name="feature[]" id="feature-a"/>
<input type="checkbox" name="feature[]" id="feature-b"/>
<input type="checkbox" name="feature[]" id="feature-c"/>
<input type="checkbox" name="feature[]" id="feature-d"/>

etc

foreach( $_POST['feature'] as $feature ) {

    if( isset( $feature ) && '' !== $feature ) {
        $feature = 1; 
    }
    else {
        $feature = '';
    } 

    $features = array();
    array_push($features, $feature);
}
update_term_meta( $term_id, 'features', $features );

//This always outputs a:1 {i:0;i:1;} for some reason! No matter what I check

What am I missing?

I tried to add feature[] as name attribute
I tried to assing '' or "" to $feature

Nothing is working. Is there a mistake in my loop I can't see?

1) You need to apply `feature[]` as a `name` attribute. 2) As you were not applying any values to your checkboxes then when you select checkboxes it'll pass an array of `selected` checkboxes with a value of `Yes` and you'll not receive those values which aren't `checked` — Narendrasingh Sisodia, Dec 16 '15 at 05:38

So, there's no way to save checkboxes as an array with certain order? I mean situations where unchecked boxes also matter. Also, I ALWAYS get the same output as in code's comment, no matter what boxes I check, even if 10 checkboxes - still the same. — Solo, Dec 16 '15 at 05:46
Please check my [previous comment](http://stackoverflow.com/questions/34304601/saving-several-checkbox-inputs-as-an-array?noredirect=1#comment56351344_34304601) for you first question. And for second one you need to post the values that you were getting within your `$_POST` method `checked` and `unchecked` — Narendrasingh Sisodia, Dec 16 '15 at 05:48

foreach( $_POST['feature'] as $feature ) {

if( isset( $feature ) && $feature !=='' ) {
    $feature = 1; 
}
else {
    $feature = 0;
} 

$features = array();
array_push($features, $feature);

} update_term_meta( $term_id, 'features', $features );
