I was just checking because I thought there was a reason I avoided the
age[] type method once, like perhaps it only sent form values that had
been filled in and were not blank, but this is not the case and it does
send all values, so as I went to the extent of testing it, here's the
code in case anyone needs it ;-)
<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
$age = $_POST["age"];
if ( is_array($age) ) {
echo "There are " . count($age) . " elements in this
array.";
for ($counter=0;$counter<count($age);$counter++) {
echo "<p>Age $counter is $age[$counter]</p>";
}
} else {
echo "age is not an Array";
}
}
?>
<form action="<?php echo $_SERVER["PHP_SELF"]?>" method="post">
Age1<input type="text" name="age[]" value="10" /><br />
Age2<input type="text" name="age[]" value="20" /><br />
Age3<input type="text" name="age[]" value="30" /><br />
Age4<input type="text" name="age[]" value="40" /><br />
Age5<input type="text" name="age[]" value="50" /><br />
<input type="submit" />
</form>
