dynamic form submitting - php

Question

I have in the form like
<form action="sub.php" method="post">
<input type="text" name="username[]"><br>
<input type="text" name="hometown[]"><br>
<input type="text" name="country[]"><br>
<input type="submit" value="submit">
</form>
sub.php
$username = $_POST["username"];
foreach($_POST['username'] AS $ID => $Value){
echo "Checkbox with value ".$sValue." was checked!<br>";
}
I could get only one one input field i.e., username
Can we get all 3inputs to sub.php

Answer 1

If I understand the question
<form action="sub.php" method="post">
<input type="text" name="user[1][name]"><br>
<input type="text" name="user[1][hometown]"><br>
<input type="text" name="user[1][country]"><br>
<input type="text" name="user[2][name]"><br>
<input type="text" name="user[2][hometown]"><br>
<input type="text" name="user[2][country]"><br>
<input type="submit" value="submit">
</form>
PHP
$users = $_POST["user"];
foreach($users AS $ID => $info){
echo "user $ID ({$info['name']}) lives in {$info['hometown']}<br>"; // dollar symbol added
}
echo "all usernames: ";
$all_ids = array_keys($users);
foreach($all_ids as $current_id) {
echo $users[$current_id]['name']." ";
}

I'm not sure what your question is but there are a few issues with your html. It should be the following:
<form action="sub.php" method="post">
<input type="text" name="username"><br>
<input type="text" name="hometown"><br>
<input type="text" name="country"><br>
<input type="submit" value="submit>
</form>
I removed the brackets from the fields because brackets normally imply that you want your php code to see it as an array of values but you have single text fields.
If you want to get all of the inputs from the form you should use:
foreach($_POST AS $ID => $Value){
echo "Textbox with value ". $Value ." was used!<br>";
}
I changed it to textbox because your form doesn't have any checkboxes

try this (not elegant but should show you where its going wrong..)
$username = $_POST["username"];
foreach($_POST['username'] AS $ID => $Value){
echo "Checkbox with value ".$Value." was checked!<br>";
}
$hometown = $_POST["hometown"];
foreach($_POST['hometown'] AS $ht_ID => $ht_Value){
echo "Checkbox with value ".$ht_Value." was checked!<br>";
}
$username = $_POST["country"];
foreach($_POST['country'] AS $c_ID => $c_Value){
echo "Checkbox with value ".$c_Value." was checked!<br>";
}

If you have equal # of username,hometown,country and in correct sequence, then you can use following way
foreach($_POST['username'] AS $ID => $Value){
echo "Username ".$Value." was checked!<br>";
echo "Hometown ".$_POST['hometown'][$ID]." was checked!<br>";
echo "Country ".$_POST['country'][$ID]." was checked!<br>";
}
