我正在嘗試創建一個我是誰的測驗，其中用戶顯示圖像，並且他們選擇他們認爲圖像在Codeigniter框架內的人，並且我收到了幾個錯誤。代碼如下：Codeigniter - 測驗實施問題
的視圖（guessview.php）：
<div>
<img src="<?php echo $image ?>" width=400>
</div> <!-- div/img -->
<div>
<?php
if (!isset($iscorrect)) {
?>
<p>Who is this?
<form class="form">
<input type=hidden name=id value="<?php echo $id ?>">
<div class="radio">
<label>
<input type="radio" name="name" value="<?php echo $name1 ?>">
<?php echo $name1 ?>
</label>
</div>
<div class="radio">
<label>
<input type="radio" name="name" value="<?php echo $name2 ?>">
<?php echo $name2 ?>
</label>
</div>
<div>
<input type=submit value="Guess!">
</div>
</form>
<?php
}
else {
if ($iscorrect === true) {
// they guess correctly
?>
<h2 class="bg-success">
Correct! It's <?php echo $name ?>!
</h2>
<?php
}
else {
// they guessed wrongly
?>
<h2 class="bg-warning">
Wrong! It's not <?php echo $name ?>!
</h2>
<?php
}
?>
<a href="guess"><button class="btn btn-primary btn-sm">Next<button></a>
<?php
}
?>
</div>
</div>
模型：
<?php
class People extends CI_Model {
private $imageurls
= array(
"http://cdn2.thr.com/sites/default/files/imagecache/675x380/2014/06/harrison_ford_enders_game.jpg",

"http://www.lovebscott.com/wp-content/uploads/2015/03/featured4.jpg"
);
private $names
= array("Harrison Ford","Morgan Freeman","Salman Khan","Halle Berry","Jeremy Corbyn",
"Anne Hathaway","Meera Syal","Kanye West"
);
function __construct()
{
parent::__construct();
}
function getwho()
{
$max = count($this->names);
$whopos = rand(0,$max - 1); // randomly-chosen number
// use this randomly-chosen number to select a person
$image = $this->imageurls[$whopos];
$name = $this->names[$whopos];
// now get a wrong name
// can you work out what this is doing?
$wrong = $whopos;
while ($wrong == $whopos) {
$wrong = rand(0,$max - 1);
}
// now get a wrong name
$wrongname = $this->names[$wrong];
// now decide which name comes first and second
$choice = rand(0,1);
if ($choice == 0) {
$name1 = $name;
$name2 = $wrongname;
}
else {
$name1 = $wrongname;
$name2 = $name;
}
// return $whopos as part of the result - this will make checking later easier
return array('id' => $whopos,'image' => $image,'name1' => $name1,'name2' => $name2);
}
function getPerson($id)
{
return array('id' => $id,'image' => $this->imageurls[$id]);
}
function isCorrectAnswer($id,$name)
{
$answer = $this->names[$id];
if ($answer == $name) {
return true;
}
else {
return false;
}
}
}
控制器：
<?php
class Guesser extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->model('people');
}
function guess()
{
$guess = $this->input->get('name',false);
$personid = $this->input->get('id',false);
if ($guess === false) {
// no guess provided, so create a guess and display it
$newguess = $this->people->getwho();
$this->load->view('guessview',$newguess);
}
else {
$res = $this->people->isCorrectAnswer($personid,$guess);
$person = $this->people->getPerson($personid);
$this->load->view('guessview',
array('image' => $person['image'],
'iscorrect' => $res,'name' => $guess));
}
}
}
是即時接收的誤差如下：

我編輯的陣列中圖像在模型和控制器之間傳輸。
我的假設是，它在運行之前與codeigniter的配置有關。如果有人遇到過這些錯誤，我將不勝感激。
謝謝。
