Checkbox values not saved correctly into a wordpress meta array

Question

I am trying to save the checkbox fields in an array into a user meta key. With the below code I am getting the error below:

Notice: Undefined offset: 1 in xyz path on line 54 value="">

Notice:Undefined offset: 2 in xyz path on line 54 value="">

Notice: Undefined offset: 3 in xyz path on line 54 value="">

Notice: Undefined offset: 4 in xyz path on line 54 value="">

Notice: Undefined offset: 5 in xyz path on line 54 value="">

Notice: Undefined offset: 6 in xyz path on line 54 value="">

$dps_is_store_closed = get_user_meta($user_id, '_dps_is_store_closed', true);
$daysweek2 = array(
'0' => 'Monday',
'1' => 'Tuesday',
'2' => 'Wednesday',
'3' => 'Thursday',
'4' => 'Friday',
'5' => 'Saturday',
'6' => 'Sunday',
);
<table border="0">
  <tr>
     <th>Closed for the Day</th>
  </tr>
 <tr>
   foreach($daysweek2 as $key => $value){
    <td>
      <input type="checkbox" id="dps_is_store_closed[<?php $key?>]" name="dps_is_store_closed[<?php $key?>]" <?php checked( $dps_is_store_closed[$key], 'on' ); ?> value="">    
    </td>
   }
</tr>

change <input type="checkbox" id="dps_is_store_closed[<?php $key?>]" name="dps_is_store_closed[<?php $key?>]" <?php checked( $dps_is_store_closed[$key], 'on' ); ?> value=""> to this <input type="checkbox" id="dps_is_store_closed[<?php echo $key;?>]" name="dps_is_store_closed[<?php echo $key;?>]" <?php checked( $value, 'on' ); ?> value=""> — Death-is-the-real-truth

I think it should be for example id="<?php echo $dps_is_store_closed[$key]; ?>" - change the name like that too — Antonios Tsimourtos

The above solution resolves the current error. The next problem i am facing is on saving the post value. The checkbox that are not checked is showing Notice: Undefined offset: 3 in /path on line 63 value="on"> — Himani

For example: Array ( [0] => on [1] => on [2] => on [4] => on [5] => on [6] => on ) [3] is not inserted — Himani

Is your input tag should be:

id="dps_is_store_closed[<?php echo $key;?>]"

instead:

id="dps_is_store_closed[<?php $key?>]"

And:

name="dps_is_store_closed[<?php echo $key;?>]"

instead:

name="dps_is_store_closed[<?php $key?>]"

The next problem i am facing is on saving the post value. The checkbox that are not checked is showing Notice: Undefined offset: 3 in /path on line 63 value="on"> For example: Array ( [0] => on [1] => on [2] => on [4] => on [5] => on [6] => on ) [3] -> '' is not inserted

Have you tried checked($dps_is_store_closed[$key], 1, false)?

After adding another value in hidden input resolved this issue For example: <input type="hidden" name="dps_is_vendor_closed[<?php echo $key?>]" value="off">
