我可以隐藏ID的值并显示其字段吗?

I really need help. I have plsvote.php which the student will choose a candidates and here's the code

plsvote.php

<input name="<?php echo $rowasa['pos_name'] ?>" style="margin-left:-19px;" type="radio" value="<?php echo $rows['candid'] . "-" ."&nbsp". $rows['lastname'] .",". "&nbsp". $rows['firstname'] ?>"> 

Here's my explanation of why should I put the value like candid it's because this is the one who will handle the count+1 because it's unique if I will not include the candid it will not count the vote

Here's my preview.php codes:

<h2 class="fs-title"><?php echo $exrxrxrx ?></h2>
<input type="hidden"  style = "text-color:white;" value="<?php echo explode("#", $_POST[$exrxrxrx])[0] ?>" name="votes[]" /><?php echo explode("#", $_POST[$exrxrxrx])[0] ?><br>

This is where the value that I put in the pslvote.php

Is there a way that in the preview.php it will not display the candid and disply only the name?
