Create several checkbox with the same name can be considered wrong? Since the value is what defines the dado of checkbox. Or should I really have names different?

<tr>
  <td>Status</td>
  <td colspan="3">
    <input type="checkbox" name="chk_stat[]" value="single" id="chk_stat">single

    <input type="checkbox" name="chk_stat[]" value="married" id="chk_stat">Married

    <input type="checkbox" name="chk_stat[]" value="divorcee" id="chk_stat">Divorcee

    <input type="checkbox" name="chk_stat[]" value="student" id="chk_stat">Student
  </td>
</tr>

  • Wrong is to put the same id on all elements.

  • This way no, what is wrong is the repetition of Ids, Ids should be unique (Why it is considered wrong/bad to repeat an HTML ID?). The form of the Names is OK, they will be treated with a vector when received in the back-end.

  • Assuming the name was only name="chk_stat" would no longer be correct?

  • Then will always return the last marked. It would be incorrect to checkbox.

That is correct.

Avoid just repeating the ID as they should be unique.

in PHP you can recover them with foreach

foreach($_POST['chk_stat'] as key){
   //tratamento para cada combo selecionado
}

With the same name only makes sense even use as array (adding [] at the name, as you are doing). Unlike radio, usually each checkbox has a name unique, but there is no problem in using this way.

The incorrect is to use the same name without the brackets, because the back-end will receive only the last checkbox marked.

The only possible problem, perhaps, is that if you mark only the last one, for example, the array received in the back-end will always start from the index [0], that is to say:

Array ( [0] => student )
