Question

我有以下情况：如果用户发布了消息，则其他用户可以批准该消息，但不能批准作者，该作者应该只能编辑或删除它。

以下if语句应该适用于该语句，但它不起作用。

<td>
  <?php $author = array(
    $message->user_id == $this->session->userdata('id')
  ); ?>
  <?php if($author): ?>
  <?php echo anchor('admin/messages/edit/'.$message->id.'', 'Edit', 'class="btn btn-primary"'); ?>
  <?php echo anchor('admin/messages/delete/'.$message->id.'', 'Delete', 'class="btn btn-danger"'); ?>
  <?php endif; ?>
  <?php if(!$author): ?>
  <?php echo anchor('admin/messages/approve/'.$message->id.'', 'Approve', 'class="btn btn-success"'); ?>
  <?php endif; ?>
</td>

下面的代码是我的CONTROLLER中的 approve METHOD，它应该在将数据传递给MODEL之前检查条件

public function approve($id)
{
    $this->db->select('*');
    $this->db->from('approval');
    $this->db->join('messages', 'messages.id = approval.sms_id');
    $query = $this->db->get();
    $first_approval = $query->row('first_approval');
    $second_approval = $query->row('second_approval');
    $third_approval = $query->row('third_approval');

    if ($first_approval == null) {
        $data  = array(
            'first_approval' =>  $this->session->userdata('user_id')
        );

        $approval_data  = array(
            'approvals' => 'one'
        );

        $this->Message_model->some_approve($id, $approval_data);

        $this->Message_model->approve($id, $data);
        //Activity array
        $data  = array(
            'resource_id' => '',
            'type'        => 'message',
            'action'      => 'approved',
            'user_id'     => $this->session->userdata('user_id'),
            'message'     => 'Message was approved'

        );
        //Insert Activity
        $this->Activity_model->add($data);

        //isset Message
        $this->session->set_flashdata('success', 'Your approval was send');

        //Redirect
        redirect('admin/messages');

    } elseif ($second_approval == null && $this->session->userdata('user_id') != $first_approval) {

        $data  = array(
            'second_approval' =>  $this->session->userdata('user_id')
        );

        $approval_data  = array(
            'approvals' => 'two'
        );

        $this->Message_model->some_approve($id, $approval_data);

        $this->Message_model->approve($id, $data);

        //Activity array
        $data  = array(
            'resource_id' => '',
            'type'        => 'message',
            'action'      => 'approved',
            'user_id'     => $this->session->userdata('user_id'),
            'message'     => 'Message was approved'
        );

        //Insert Activity
        $this->Activity_model->add($data);

        //isset Message
        $this->session->set_flashdata('success', 'Your approval was send');

        //Redirect
        redirect('admin/messages');

    } elseif ($third_approval == null && $this->session->userdata('user_id') != $second_approval && $this->session->userdata('user_id') != $first_approval) {
        $data  = array(
            'third_approval' =>  $this->session->userdata('user_id')
        );
        $approval_data  = array(
            'status'    => 'Approved',
            'approvals' => 'three'
        );

        $this->Message_model->approve($id, $data);
        $this->Message_model->some_approve($id, $approval_data);

        //Activity array
        $data  = array(
        'resource_id' => '',
        'type'        => 'message',
        'action'      => 'approved',
        'user_id'     => $this->session->userdata('user_id'),
        'message'     => 'Message was approved'

        );

        //Insert Activity
        $this->Activity_model->add($data);

        //isset Message
        $this->session->set_flashdata('success', 'Your approval was send and the message has passed');

        //Redirect
        redirect('admin/messages');

    } elseif ($third_approval == $this->session->userdata('user_id') || $this->session->userdata('user_id') == $second_approval || $this->session->userdata('user_id') == $first_approval) {
        //isset Message
        $this->session->set_flashdata('success', 'You already have send an approval');

        //Redirect
        redirect('admin/messages');

    } else {

        $approval_data  = array(
            'status'      => 'Approved',
            'approvals'   => 'three'
        );

        $this->Message_model->some_approve($id, $approval_data);

        //isset Message
        $this->session->set_flashdata('success', 'Your approval was send and the message has already been send');

        //Redirect
        redirect('admin/messages');
    }
}

以下方法正在运作

public function approve($id, $data) {
    $this->db->where('sms_id', $id);
    $this->db->update('approval',$data);
}

public function some_approve($id, $approval_data)
{
    $this->db->where('id', $id);
    $this->db->update('messages',$approval_data);
}

我的控制器和按钮上的if条件是我需要帮助的条件，因为它们没有显示任何错误，但是它们不能正常工作

Answer 1

首先，你的if条件是错误的：

它应该是这样的：

<?php if($message->user_id && $message->user_id == $this->session->userdata('id')): ?>

HTML Data

<?php else:?>

HTML Data

检查用户是否已提交批准
