PHP使用id属性获取表单数据

Question

I'm making a form with checkboxes and radiobuttons I use the value as price, which I calculate with a script so I get the total price of the selected checkboxes and radiobuttons.

<script>
function calcscore() {
    score = 0;
    $(".calc:checked").each(function () {
        score += Number($(this).val());
    });
    $("#price").text(score.toFixed(2));
    $("#sum").val(score)
}
$().ready(function () {
    $(".calc").change(function () {
        calcscore()
    });
});
</script>

<input type="radio" id="1" value="40" class= "calc" name = "780143050"> Gezichtsbehandeling (incl.)<br>
<input type="radio" id="2" value="40" class = "calc" name = "780143050"> Massage<br>
<input type="radio" id="3" value="75" class = "calc" name = "780143050"> beide 
<span id="output"></span><input type="hidden" name="sum" id="sum" value="0">
                <p>Totaal extra's : €  <span id="price">0</span>

I have the following PHP

test.php

<?php
   echo("keuze : " . $_POST['780143050'] . "<br />
");
?>

I in my php script the value and the ID. How can I echo the ID of the selected radiobutton?

Answer 1

There are 2 ways to do this:

1. change the value of value to the value of the id
2. add the value of the id to the value

html:

<input type="radio" id="2" value="40|2" class = "calc" name = "780143050"> Massage<br>

js:

<script>
function calcscore() {
    score = 0;
    $(".calc:checked").each(function () {
        score += Number($(this).val().split('|')[0]);
    });
    $("#price").text(score.toFixed(2));
    $("#sum").val(score)
}
$().ready(function () {
    $(".calc").change(function () {
        calcscore()
    });
});

php

<?php
   echo("keuze : " . split('|',$_POST['780143050'])[1] . "<br />
");
?>
