Taking user input from form to populate an array

[morrism35]

I know in java this was almost trivial to do.

1. Use a for loop for how many values you want to populate the array with.

2. Enter your user data and assign it to the array.

 

This does not seem so easy in php. This is kind of what i've been working on but it just endlessly keeps asking

me for the user endput even though i'm able to output the values, but I want this to be an area that i can sort etc.

 

 

for($count=0; $count<=3; ++$count){

if($_POST['submit']){

$Signs=$_POST['sign'];

 

?>

 

 

<form action='AlphabetizeSigns.php' method='POST'

enctype='multipart/form-data'>

Type in a zodiac sign<input type='text' name='sign'>

 

 

<input type='submit' name='submit' value='submit'>

Not really sure what your doing but this will put the form data into an array. If you are wanting to save the array and keep adding to it you would need to put the data in a session.

<?php
if($_POST){
$signs[]=$_POST['sign'];
echo "<pre>";
print_r($signs);
echo "</pre>";
}
?>
<form method='post'>
Type in a zodiac sign<input type='text' name='sign'>
<input type='submit' name='submit' value='submit'>
</form>

What I'm trying to do is have the user input 12 names in any order and sort those names in alphabetical order. Php just seems like

it doesn't populate an array like other languages like java or c++.

Here ya go. This is not accounting for 12 names. You would just need to count the elements in the array before adding a new one.

 

<?php
session_start();
if ($_POST)
    {   
    $_SESSION['signs'][] = $_POST['sign'];
    }
if (isset($_SESSION['signs']))
    {
    echo "Number of Elements: " . count($_SESSION['signs']);
    sort($_SESSION['signs']);
    echo "<pre>";
    print_r($_SESSION['signs']);
    echo "</pre>";
    }
?>
<form method='post'>
Type in a zodiac sign<input type='text' name='sign'>
<input type='submit' name='submit' value='submit'>
</form>

Thanks you didn't have to do that. I appreciate it but really trying to learn and understand this. i'm going to look up what autoglobal $_session means.
