在php中获取未发布输入的值

Question

very common to us to get the value of the post input type with data. but now i want to get if the checbox is check or unchecked. here is my code:

while (!$listof_artist->EOF) {
    $id = $listof_artist->fields['id'];
    $arr_id[] = $id;

    echo "<tr><td><input type='checkbox' value='".$id."' name='chkid[]' id='chkid[]' /></td>";
}

if(isset($_POST['submit'])){
    foreach($_POST['chkid'] as $checkbox){
        //code for add
    }

here is my algorithm: if submit is post then

for each checbox is check
    //add

foreach checbox not check
        //code for not check

Please help. thank you

Similar to what the other answers have already pointed out, here is a way to do it:

while (!$listof_artist->EOF) {
    $id = $listof_artist->fields['id'];
    $arr_id[] = $id;

    echo "<tr><td><input type='checkbox' value='$id' name='$id' id='$id' /></td>";
}

if(isset($_POST['submit'])){
    foreach($arr_id as $checkbox){
        if (isset($_POST[$checkbox])) {
            // Checkbox is checked
            echo 'Artist id ' . $checkbox . ' is checked <br/>';
        }
        else {
            // Checkbox is NOT checked
            echo 'Artist id ' . $checkbox . ' is NOT checked <br/>';
        }
}
