Hello. First of all, English is not my main language so I'm sorry if I make some mistakes in my text... Anyway, my problem is that I really have no clue how to do this task I was given: I need to create a form where I can write names and then save them and do this for unlimited times. After I have added names, I need to sort them alphabetically from A-Z. I have done it like this so far, just the sorting is missing. This job has two files, index.php and persons.php. index.php:
<?php
include "persons.php";
?>
<!DOCTYPE html>
<!-- -->
<html>
<head>
<meta charset="UTF-8">
<title><Task</title>
</head>
<body>
<form action="">
First name: <input type="text" name="first_name">
Last name: <input type="text" name="last_name"><br>
<input type="submit" name="do" value="Add"><br>
Alphabetical order by Last name:<input type="radio" name="alphabetical" value="ln_first" checked><br>
Alphabetical order by First name:<input type="radio" name="alphabetical" value="fn_first"><br>
<input type="submit" name="do" value="Sort">
</form>
<?php
if (isset($_GET["first_name"]) && isset($_GET["last_name"]) && $_GET["first_name"] != "" && $_GET["last_name"] != "" || $_GET["do"] == "Sort")
{
$persons = new persons($_GET["first_name"], $_GET["last_name"]);
$str = "";
switch ($_GET["do"])
{
case "Add":
$persons->Add($_GET["first_name"], $_GET["last_name"]);
break;
case "Sort":
$str = $persons->Sort();
break;
default:
$str = "Something went wrong.";
}
print($str);
}
else
print("Give a real name.");
?>
</body>
</html>
persons.php:
<?php
session_start();
/**
*/
class persons
{
private $persons;
public function __construct()
{
if (isset ($_SESSION["persons"]))
$this->persons = $_SESSION["persons"];
else
$this->persons = array();
}
public function __destruct()
{
$_SESSION["persons"] = $this->persons;
}
/**
*
* @param type $first_name
* @param type $last_name
* @return string
*/
public function Add($first_name, $last_name)
{
$this->persons[$first_name] = $last_name;
return "Added.";
}
/**
*
* @return string
*/
public function Sort()
{
$str = "<table>\n";
foreach ($this->persons as $first_name => $last_name)
{
$str .= "<tr><td>$first_name</td><td>$last_name</td></tr>\n";
}
$str .= "</table>\n";
return $str;
}
}
So I just need to add the sorting somewhere in the code, but I just don't know where. This task was given in my school and it is the first course of php coding. I am a newbie in this thing...
