CakePHP找不到Controller

Question

我已经在CakePHP上创建了一个项目，但是当我从视图中发送表单数据时，它显示了Missing Controller。我也为此创建了控制器。这是守则。

Index.ctp           

<title>Student</title>
<center><h1>REGISTRATION FORM</h1></Center>
<?php 

echo $this->Form->create(null, ['url' => ['controller' => 'Controller', 'action' => 'save']])
?>
    <table class="table">
        <tr>
            <td>Fname<input type="text" name="fname" ></td>
        </tr>
                <tr>
            <td>Lname<input type="text" name="lname" ></td>
        </tr>
        <tr>
            <td>Email<input type="text" name="email" ></td>
        </tr>
        <tr>
            <td>Password<input type="text" name="password" ></td>
        </tr>
                <tr>
            <td>Gender<input type="text" name="gender" ></td>
        </tr>
        <tr>
            <td>About<input type="text" name="about" ></td>
        </tr>
            <td><input type="submit" class="btn btn-primary" value="Save"></td>
        </tr>
</table>
<center><h1>DISPLAY DATA</h1></Center>
<?php echo $this->Form->end();?>
<table>
    <thead>
        <tr>
            <th>First Name</th>
            <th>Last Name</th>

            <th>Password</th>

            <th>About</th>
            <th>Edit</th>
            <th>Delete</th>
        </tr>
    </thead>
    <tbody>
        <?php 
            foreach($data as $row)
            {
                ?>
                    <tr>
                        <td><?= $row->fname ?></td>
                        <td><?= $row->lname ?></td>
                        <td><?= $row->email ?></td>
                        <td><?= $row->password ?></td>
                        <td><?= $row->gender ?></td>
                        <td><?= $row->about ?></td>
                        <td><?= $this->Html->link('Edit',array('controller'=>'Stud','action'=>'edit'.'/'.$row->id))?>|
                        <?= $this->Html->link('Delete',array('controller'=>'Stud','action'=>'delete'.'/'.$row->id))?>

                    </tr>
                <?php

    Please help, My project is stuck because of this

Answer 1

echo $this->Form->create(null, ['url' => ['controller' => 'Controller', 'action' => 'save']])

将此更改为

echo $this->Form->create(null, ['url' => ['controller' => 'Stud', 'action' => 'save']])
