检查用户是否已提交批准

Question

I have the followin scenario: if a user has posted a message, other users are able to approve the message but not the author, which should only be able to edit or delete it.

The below if statement is supposed to work for that but it's not working.

<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>

The code below is the approve METHOD in my CONTROLLER which is supposed to check the condition before passing data to the MODEL

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');
    }
}

The METHODS below are working

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);
}

The if conditions in my controller and on the buttons are the ones which I need help on because the are not showing any error but they are not working as they should

Answer 1

Well first thing your if condition below is wrong:

It should be something like this:

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

HTML Data

<?php else:?>
