Answer 1

If you submit multiple fields with the same name, then PHP will only put the last one into $_POST / $_GET.
The exception is when you end the name with [] in which case it will generate an array instead.
However, checkboxes are only successful controls when checked, so simply adding [] to the names will cause the association between each set of date to be lost.
Instead of submitting all the data about each jobwork (you aren't trying to change it, otherwise you wouldn't be using hidden inputs!), put all the data you need into the checkbox input. Look up the rest of the data on the server.
<td><input type='checkbox' name="jobwork[]" value="<?= htmlspecialchars($row->id); ?>"/></td>
I've used $row->id as an example. I don't know how your data is structured on the server.
You will then be able to do:
foreach ($_POST['jobwork'] as $jobwork_id) {
$row = look_up_jobwork_by_id($jobwork_id);
}
… only the checked checkboxes values will appear in that array.

You have issue in the first checkbox code.
Name is given as value, both names should be same for the checkbox,
and get the request as an array
<?php foreach ($item as $key=>$value){
$decoded = json_decode($value['jobWorkJsonString']); ?>
<?php foreach($decoded as $row){ ?>
<tr class="odd gradeX">
<td><input type='checkbox' name="jobwork" value="<?php echo $row->jobwork; ?>" /></td>
<td style="padding-left:0px;"><?php echo $row->jobwork; ?><input type="hidden" name="jobwork_name" value="<?php echo $row->jobwork; ?>"></td>
<td style="padding-left:0px;"><?php echo $row->description; ?><input type="hidden" name="jobwork_description" value="<?php echo $row->description; ?>"></td>
<td style="padding-left:0px;"><?php echo $row->jobPrice; ?><input type="hidden" name="price" value="<?php echo $row->jobPrice; ?>"></td>
<?php } ?>
</tr>
<?php } ?>
get the value of job_work as an array, you will get the selected job_work
