Answer 1

你可以这样做：

var_dump($_POST['Filling']);

或者只是这个：

<?php
if(!empty($_POST['Filling'])) {
    foreach($_POST['Filling'] as $check) {
            echo $check;     
    }
}
?>

告诉我它是否有效=）

Answer 2

事实上，您接受填写清单。在您的代码中，您执行此操作：

foreach($z as $item){
    $fillr=$item;
}

将其替换为：

$fillr = '';
foreach($z as $item){
    $fillr .= '- ' . $item . '<br/>';
}

它应该更好。

评论：

#so let's say $z is an array :

$z = [1,2,3,4];

#then you say, for each element of the array as you will call $item, I do something

foreach($z as $item){
    $fillr=$item; #here you say : for each element of $z (1,2,3,4), I put this value into $fillr.
}

#so let's do the loop together.
# First pass, $item == 1, so $fillr == 1.
# Second pass, $item == 2, so $fillr == 2.
# ...
# Last pass, $item == 4, so $fillr == 4.

# so then when you show $fillr it's the last item of the list (here 4).


# using PHP, .= means concatenate.
# for instance :
$a = "hello ";
$a .= "world";
echo $a;

> hello world


So basically, what I'm doing is :
Having an empty string I'll call $fillr.
For every element of the list,
  Append "the_element plus a <br/>" to $fillr

so then when you output $fillr it looks sexy.


Do you get it bud?
