【问题描述】：
我是 cakePHP 新手，所以我可能遗漏了一些明显的东西。
我有一个正在工作并保存到数据库的添加表单，但突然停止了。我认为我没有添加任何重要的东西，主要是样式化的东西......不幸的是，我的最后一次备份是在我完成添加功能之前，所以我没有办法回到它工作的时候。如果有人可以看看我哪里出错了，我将不胜感激！
我的任务模型：
App::uses('AuthComponent', 'Controller/Component');
class Task extends AppModel {
public $belongsTo = 'User';
public $validate = array(
'task_name' => array(
'custom' => array(
'rule' => array('custom', '/^[a-z0-9 ]*$/i'),
'required' => true,
'message' => 'This field accepts letters and numbers only.'
),
'maxLength' => array(
'rule' => array('maxLength', 50),
'message' => 'Task name cannot exceed 50 characters'
)
),
'frequency' => array(
'alphaNumeric' => array(
'rule' => 'alphaNumeric',
'allowEmpty' => true
)
),
'day' => array(
'alphaNumeric' => array(
'rule' => 'alphaNumeric',
'allowEmpty' => true
)
),
'user_id' => array(
'numeric' => array(
'rule' => 'numeric'
)
),
'month_type' => array(
'alphaNumeric' => array(
'rule' => 'alphaNumeric',
'required' => false
)
),
'month_number' => array(
'alphaNumeric' => array(
'rule' => 'alphaNumeric',
'required' => false
)
),
'month_day' => array(
'alphaNumeric' => array(
'rule' => 'alphaNumeric',
'allowEmpty' => true
)
),
'day_number' => array(
'alphaNumeric' => array(
'rule' => 'alphaNumeric',
'required' => false
)
)
);
}
我的 TasksController 文件中的添加函数：
public function add() {
if ($this->request->is('post')) {
$this->Task->create();
if ($this->Task->save($this->request->data)) {
$this->Session->setFlash(__('Task saved!'));
$this->redirect(array('action' => 'index'));
}
else {
$this->Session->setFlash(__('The task could not be saved'));
}
}
}
还有我的 tasks/add.ctp 文件中的表单：
<?php
echo $this->Form->create('Task',array('class' => 'taskForm'));
$userId = $this->Session->read('Auth.User.id');?>
<fieldset>
<legend class="welcomeText"><?php echo __('Add a Task'); ?></legend>
<?php
echo $this->Form->hidden('user_id', array('value' => $userId));
echo $this->Form->input('task_name', array('label' => 'Task Name', 'maxLength' => 50));
//set frequency
echo "<p>How often should this task be done?</p>";
$options = array('unset' => 'Decide Later','daily' => 'Daily','weekly' => 'Weekly','monthly' => 'Monthly');
$attributes = array('value' => 'unset','separator' => '<br/>','class' => 'frequencyRadio','legend' => false);
echo $this->Form->radio('frequency', $options, $attributes);
//optional answers
//if "weekly" is selected
echo "<div id=\"weeklyRadio\" >";
echo "<p>Set a day of the week for this task?</p>";
$options = array('unset' => 'Decide later','monday' => 'Monday','tuesday' => 'Tuesday','wednesday' => 'Wednesday',
'thursday' => 'Thursday','friday' => 'Friday','saturday' => 'Saturday','sunday' => 'Sunday');
$attributes = array('value' => 'unset','separator' => '<br/>','class' => 'weeklyRadio','legend' => false);
echo $this->Form->radio('day',$options,$attributes);
echo "</div>";
//if "monthly" is selected
?>
<div id="monthlyRadio">
<p>Schedule this task?</p>
<input type="radio" name="data[Task][month_type]" id="TaskMonthTypeUnset"
value="unset" class="monthlyRadio" required="required" checked="checked" />
<label for="TaskMonthTypeUnset">Decide later</label><br/>
<input type="radio" name="data[Task][month_type]" id="TaskMonthTypeNumber"
value="number" class="monthlyRadio" required="required" />
<label for="TaskMonthTypeNumber">
<?php
echo "On the ";
$options = array(1 => '1st',2 => '2nd',3 => '3rd',4 => '4th',5 => '5th',6 => '6th',7 => '7th',8 => '8th',9 => '9th',
10 => '10th',11 => '11th',12 => '12th',13 => '13th',14 => '14th',15 => '15th', 16 => '16th',
17 => '17th',18 => '18th',19 => '19th',20 => '20th',21 => '21st',22 => '22nd',23 => '23rd',
24 => '24th',25 => '25th',26 => '26th',27 => '27th',28 => '28th',29 => '29th',30 => '30th',31 => '31st');
echo $this->Form->select('month_number',$options,array('value' => null));
echo " of the month";
?>
</label><br/>
<input type="radio" name="data[Task][month_type]" id="TaskMonthTypeDay" value="day" class="monthlyRadio" required="required" />
<label for="TaskMonthTypeDay">
<?php
echo "On the ";
$options = array(1 => '1st',2 => '2nd',3 => '3rd',4 => '4th',5 => '5th',6 => 'last');
echo $this->Form->select('day_number',$options,array('value' => null));
echo " ";
$options = array('monday' => 'Monday','tuesday' => 'Tuesday','wednesday' => 'Wednesday',
'thursday' => 'Thursday','friday' => 'Friday','saturday' => 'Saturday','sunday' => 'Sunday');
echo $this->Form->select('month_day',$options,array('value' => null));
echo " of the month";
?>
</label>
</div>
<?php
echo $this->Form->submit('Add Task', array('class' => 'formSubmit', 'title' => 'Create Task') );
?>
</fieldset>
<?php echo $this->Form->end(); ?>
还有一个显示和隐藏可选单选按钮的 javascript 文件，但我认为这与它停止保存到数据库的原因没有任何关系。
当我单击表单上的“添加任务”按钮时，它根本不执行任何操作（不保存到数据库，也不像以前那样重定向到 index.ctp 视图）。不知道我在这里错过了什么！
更新
解决了问题！我在表单中指定默认值为 null 的位置，它传递了一个空字符串。数据模型需要 'month_number' 和 'day_number' 的数值，所以它没有处理。
我通过在选择列表中添加 0 => '' 并指定 0 作为默认值来修复它，现在它可以正常工作了。
感谢您的帮助！
