我本周刚刚开始使用CakePHP(实习所需),而且我开始使用PHP并不是很好。 无论如何,我需要以下帮助:
如果记录只有空字段,怎么才能显示?
根据上面的图片,我只希望显示带有空标题/日期的行,同时隐藏另一行。
在另一个页面上,我希望显示相同的记录,但这一次,只显示具有完全填充字段的记录,同时隐藏具有空字段的记录。
编辑:
查看:
<?php foreach ($users as $user): ?>
<tr>
<td><?= $this->Number->format($user->id) ?></td>
<td><?= h($user->username) ?></td>
<td><?= h($user->name) ?></td>
<td><?= h($user->phone) ?></td>
<td><?= h($user->email) ?></td>
<td><?= h($user->role) ?></td>
<td><?= $this->Number->format($user->status) ?></td>
<td class="actions">
<?= $this->Html->link(__('View'), ['action' => 'view', $user->id]) ?>
<?= $this->Html->link(__('Edit'), ['action' => 'edit', $user->id]) ?>
<?= $this->Form->postLink(__('Delete'), ['action' => 'delete', $user->id], ['confirm' => __('Are you sure you want to delete # {0}?', $user->id)]) ?>
</td>
</tr>
<?php endforeach; ?>
型号:
public function initialize(array $config)
{
parent::initialize($config);
$this->table('users');
$this->displayField('name');
$this->primaryKey('id');
}
public function validationDefault(Validator $validator)
{
$validator
->integer('id')
->allowEmpty('id', 'create');
$validator
->notEmpty('username', 'A username is required');
$validator
->notEmpty('password', 'A password is required');
$validator
->allowEmpty('name');
$validator
->allowEmpty('phone');
$validator
->email('email')
->allowEmpty('email');
$validator
->add('role', 'inList', [
'rule' => ['inList', ['admin', 'editor', 'sales_user', 'field_user']],
'message' => 'Please select a role']);
$validator
->add('status', 'inList', [
'rule' => ['inList', ['1', '2', '3']],
'message' => 'Please select a status']);
return $validator;
}
控制器:
public function index()
{
$users = $this->paginate($this->Users);
$this->set(compact('users'));
$this->set('_serialize', ['users']);
}
这是我第一次发帖提问,如果我需要提供任何进一步的细节等,请告诉我。 谢谢。

此代码选择名称字段为空的用户。
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
presenter.onCukRulesClicked();
final LinearLayout checkboxesContainer = (LinearLayout) findViewById(R.id.checkboxes_container);
final LinearLayout rootView = (LinearLayout) findViewById(R.id.linearLayout2345);
final LinearLayout leftContainer = (LinearLayout) findViewById(R.id.left_container);
if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE)
if (isChecked) {
leftContainer.removeView(checkboxesContainer);
leftContainer.invalidate();
rootView.addView(checkboxesContainer);
} else {
rootView.removeView(checkboxesContainer);
rootView.invalidate();
leftContainer.addView(checkboxesContainer);
}
}
