Question

I want to know how to handle multiple inputs from a form with multiple atributes.
This code generates my fields:

<form method="POST" action="test5.php" id="1">
            <?
            if($_SESSION["peoplecount"] != 0){
            for ($i = 0; $i <= $_SESSION["peoplecount"]; $i++) {
             echo ' Name<input type="text" name="'.$i.'">  Adult<input type="radio" name="'.$i.'" value="adult" /> Minor<input type="radio" name="'.$i.'" value="minor" /> <br/>';
            }           }
            ?>
            <input class="button" type="submit" value="I/We Agree" style="width:200px;"/>
            </form>

once submitted — or test5.php as its mentioned in the “action” part,

foreach ($_POST as $key => $value) {
  print "{$key}: {$value}<br />";
}

and the output is

0: adult
1: adult
2: adult
3: adult

Notice it has 0, 1, 2… and then adult. It does not even mention the name of the person from the text input.
I can alter the form to:

        </blockquote>
        <form method="POST" action="test5.php" id="1">
        <?
        if($_SESSION["peoplecount"] != 0){
        for ($i = 0; $i <= $_SESSION["peoplecount"]; $i++) {
         echo ' Name<input type="text" name="usersname" id="usersname">  Adult<input type="radio" name="age" value="adult" id="age"/> Minor<input type="radio" name="age" value="minor" id="age"/> <br/>';
        }           }
        ?>
        <input class="button" type="submit" value="I/We Agree" style="width:200px;"/>
        </form>

Using the same test5.php, I get

usersname:
age: adult

The value of the age is not posted and the the foreach loop in test5.php ends, hence the line return, before it completly runs through one complete post.

I hope I did a good enough job explaining.
I want my output to be:

SomeName Adult

SomeOtherName Minor
….

Your problem is that you are creating two form inputs with name='$i', and the second one (the radio button) is overwriting the first. I would suggest instead that you use a string including $i to build the name attributes:

for ($i = 0; $i <= $_SESSION["peoplecount"]; $i++) {
    echo ' Name<input type="text" name="name-'.$i.'">  Adult<input type="radio" name="age-'.$i.'" value="adult" /> Minor<input type="radio" name="'.$i.'" value="minor" /> <br/>';
}

Now your $_POST array will look like:

name-0: somename age-0: Adult
name-1: othername age-1: Minor
...

An even better way to handle it is to use arrays as form name attributes with [] (Note I’ve switched to double-quotes here, to avoid all the extra concatenation and complicated quoting.)

for ($i = 0; $i <= $_SESSION["peoplecount"]; $i++) {
   echo " Name<input type='text' name='name[$i]'>  Adult<input type='radio' name='age[$i]' value='adult' /> Minor<input type='radio' name='age[$i]' value='minor' /> <br/>";
}

In this case, your $_POST looks like:

name: Array(
 0: somename,
 1: othername
),
age: Array (
 0: adult,
 1: minor
)

To access them, you can use a foreach loop like so:

foreach ($_POST['name'] as $key=>$name) {
  echo "Name: $name  Age: {$_POST['age'][$key]}";
}
