如何根据条件加载视图页面

Question

我有两个单选按钮和一个复选框。如果单选按钮被选中，我想加载一个视图页面（Receipt_view）如果单选按钮和复选框都被选中，我想加载另一个视图页面（Receipt_View1） ...我的问题是，如果同时选中单选按钮和复选框，我将输出作为 2 个视图页面（即两个视图页面都加载了 Receipt_view 和 Receipt_view 1 ），但我希望 Receipt_view1 在两个视图页面都加载时加载单选按钮和复选框被选中.. 控制器代码：

    if ($this->input->post('all'))
        {
        $this->db->where('date >=', $newDate);
        $this->db->where('date <=', $newDate2);
        $this->db->select('*');
        $this->db->from('purchasebill');
        $this->db->order_by("date", "asc");
        $this->db->join('parmaster','parmaster.Pcode = purchasebill.partyname','left outer');
  $query = $this->db->get()->result_array();
        $data['query'] = $query;
        $this->load->view('Receipt_View', $data);

}

    if($this->input->post('all'))
    {
        if($this->input->post('item')){

        if ($this->input->post('all'))
        {
            if($this->input->post('item')){
            $this->db->where('billdate >=', $newDate);
        $this->db->where('billdate <=', $newDate2);
        $this->db->select('vno,Prdtname,Qty,bundle');
        $this->db->from('purchaseitem');
            $this->db->order_by("vno", "asc");
            //$this->db->join('purchasebill', 'purchasebill.no = purchaseitem.billno','left outer');
            //$this->db->join('parmaster','parmaster.pcode = purchasebill.partyname');
            $this->db->join('itemmaster','itemmaster.itcode = purchaseitem.Product_Code','left outer');
            $query = $this->db->get('')->result_array();
            $data['query'] = $query;
            $this->db->where('date >=', $newDate);
            $this->db->where('date <=', $newDate2);
            $this->db->select();
            $this->db->from('purchasebill');
            $this->db->order_by('voucherno');
            $this->db->group_by('voucherno');
            $this->db->join('parmaster','parmaster.Pcode = purchasebill.partyname','left outer');
            $query = $this->db->get('')->result_array();
            $data['query1'] = $query;
            $this->load->view('Receipt_View1',$data);

    }}
if($this->input->post('selected'))
    {

        if($name = $this->input->post('businessType'))
        {
            $this->db->where('date >=', $newDate);
        $this->db->where('date <=', $newDate2);
        $this->db->where('PName',$name);
        $this->db->select('*');
        $this->db->from('purchasebill');
        $this->db->order_by("date", "asc");
        //$this->db->join('salesbill', 'salesbill.no = salesitem.billno','left outer');
        $this->db->join('parmaster','parmaster.Pcode = purchasebill.partyname','left outer');
        $query = $this->db->get('')->result_array();
  $data['query'] = $query;
  $this->load->view('Receipt_View', $data);

      }
}

HTML页面：

<input type="radio" class='rd'name="all" value="op1" checked="">All
<input type="radio" name="selected" class='rd' value="op2"> Selected
<input type="checkbox" name="item" >Item description

All and selected 是单选按钮名称，item 是复选框名称..帮我解决这个问题..

Answer 1

你还没有告诉我们当它们都没有被检查时会发生什么，所以我在这里没有提到这种情况，但你可以这样做：

if ($this->input->post('all')) {
    //do something with purchasebill, no need to repeat the code
    //check if the checkbox is checked:
    if($this->input->post('item')) {
       // do something with purchaseitem
       $this->load->view('Receipt_View1',$data);
    } else {
       $this->load->view('Receipt_View',$data);
    }
}

Answer 2

在 'else' 块中编写函数，你不要在 if 条件下使用 'else'..

Answer 3

通过elseif和&&操作符我们可以根据条件加载

    if ($this->input->post('all'))
        {
        $this->db->where('date >=', $newDate);
        $this->db->where('date <=', $newDate2);
        $this->db->select('*');
        $this->db->from('purchasebill');
        $this->db->order_by("date", "asc");
        $this->db->join('parmaster','parmaster.Pcode = purchasebill.partyname','left outer');
  $query = $this->db->get()->result_array();
        $data['query'] = $query;
        $this->load->view('Receipt_View', $data);

}

    else if(($this->input->post('all')) &&($this->input->post('item')))
    {




        $this->db->select('vno,Prdtname,Qty,bundle');
        $this->db->from('purchaseitem');
            $this->db->order_by("vno", "asc");
            $this->db->join('itemmaster','itemmaster.itcode = purchaseitem.Product_Code','left outer');
            $query = $this->db->get('')->result_array();
            $data['query'] = $query;
            $this->load->view('Receipt_View1',$data);

    }}
else if($this->input->post('selected'))
    {

        if($name = $this->input->post('businessType'))
        {
            $this->db->where('date >=', $newDate);
        $this->db->where('date <=', $newDate2);
        $this->db->where('PName',$name);
        $this->db->select('*');
        $this->db->from('purchasebill');
        $this->db->order_by("date", "asc");
        //$this->db->join('salesbill', 'salesbill.no = salesitem.billno','left outer');
        $this->db->join('parmaster','parmaster.Pcode = purchasebill.partyname','left outer');
        $query = $this->db->get('')->result_array();
  $data['query'] = $query;
  $this->load->view('Receipt_View', $data);

      }
}
