顯示與查詢結果序號

Question

我想從我的數據庫獲取數據，當我展示它，我想顯示的序列號（就像列表），例如：

**Serial Number**  Name   Country 
    1.    John    USA 
    2.    Srijon   UK 

我曾嘗試一些與PHP循環，但我無法讓它工作。你能請你幫忙嗎？請注意，通過序列號我並不是指從數據庫中檢索到的值。

感謝提前:)

這裏是我的模型

//Function To Create All Batch List 
    function batch_list($perPage,$uri) { 
    $this->db->select('*'); 
    $this->db->from('batch'); 
     $this->db->join('teacher', 'batch.batchinstructor = teacher.teacherid'); 
    $this->db->order_by('batchid','DESC'); 
    $getData = $this->db->get('', $perPage, $uri); 
    if($getData->num_rows() > 0) 
    return $getData->result_array(); 
    else 
    return null; 
    } 
//End of Function To Create All Batch List 

這裏是我的控制器

function index(){ 
$this->load->library('pagination'); 
$config['base_url'] = base_url().'batchlist/index'; 
$config['total_rows'] = $this->db->get('batch')->num_rows(); 
$config['per_page'] = 20; 
$config['num_links'] = 20; 
$config['full_tag_open'] = '<div class="pagination" align="center">'; 
$config['full_tag_close'] = '</div>'; 

$this->pagination->initialize($config); 
$this->load->model('mod_batchlist'); 
$data['records']= $this->mod_batchlist->batch_list($config['per_page'] 
         ,$this->uri->segment(3)); 
    $data['main_content']='view_batchlist'; 
$this->load->view('includes/template',$data); 

} 

，這裏是我查看

<?php if(count($records) > 0) { ?> 
<table id="table1" class="gtable sortable"> 
<thead> 
<tr> 
    <th>Batch Name</th> 
    <th>Class</th> 
    <th>Batch Instructor</th> 
    <th>Edit/Delete</th> 
</tr> 
</thead> 

<tbody> 
    <?php foreach ($records as $row){ ?> 
<tr> 
    <td><a href="<?php echo base_url(); ?>batch/<?php echo $row['batchid']; ?>"><?php echo $row['batchname'];?>  </a></td> 
    <td><?php echo $row['class'];?></td> 
    <td><?php echo $row['teachername'];?></td> 
    <td> <a href="<?php echo base_url(); ?>updatebatch/get/<?php echo $row['batchid']; ?>" title="Edit"><img src="<?php echo base_url(); ?>               support/images/icons/edit.png" alt="Edit" /></a> 
    <a href="#" title="Delete"><img src="<?php echo base_url(); ?>support/images/icons/cross.png" alt="Delete" /></a> 
    </td> 
</tr> 
      <?php } ?> 

</tbody> 
</table> 
    <?php } ?> 
    <div class="tablefooter clearfix"> 
<div class="pagination"> 
<?php echo $this->pagination->create_links(); ?> 
</div> 

</div>

<?php if(count($records) > 0) { ?> 
<table id="table1" class="gtable sortable"> 
<thead> 
<tr> 
      <th>Serial</th> 
    <th>Batch Name</th> 
    <th>Class</th> 
    <th>Batch Instructor</th> 
    <th>Edit/Delete</th> 
</tr> 
</thead> 

<tbody> 
    <?php $i = $this->uri->segment(3); foreach ($records as $row){ $i++; ?> 
<tr> 
      <td><?php echo $i; ?>.</td> 
    <td><a href="<?php echo base_url(); ?>batch/<?php echo $row['batchid']; ?>"><?php echo $row['batchname'];?>  </a></td> 
    <td><?php echo $row['class'];?></td> 
    <td><?php echo $row['teachername'];?></td> 
    <td> <a href="<?php echo base_url(); ?>updatebatch/get/<?php echo $row['batchid']; ?>" title="Edit"><img src="<?php echo base_url(); ?>               support/images/icons/edit.png" alt="Edit" /></a> 
    <a href="#" title="Delete"><img src="<?php echo base_url(); ?>support/images/icons/cross.png" alt="Delete" /></a> 
    </td> 
</tr> 
      <?php } ?> 

</tbody>

    <?php } ?> 
    <div class="tablefooter clearfix"> 
<div class="pagination"> 
<?php echo $this->pagination->create_links(); ?> 
</div> 

</div> 

Answer 2

在我的情況下，第四個和第五個參數分別是每個頁面的頁碼和行數 ie：example.com/category/page/1/10 每頁有10個行的第一個頁面。

所以在這種情況下，僅僅是環

$i = $this->uri->segment(4)? (
    $this->uri->segment(4) + $this->uri->segment(5)? $this->uri->segment(5):0 
    ) 
    :0; 

前和使用內循環只是增加我的價值。

foreach ($result_obj as $key => $value) 
{ 
$i++; 
... 
} 

Answer 3

嘗試this..work像this..1,2,3,4,5

$i = 0 
while($condition) 
{ 
    echo '<td>'.$i++.'</td>'; 
}
