如何使用笨

Question

請任何人建議如何顯示下拉列表中的數據顯示在下拉列表中的數據庫表列表？ 選項屬性中將使用哪些代碼？

我的控制器

public function tableReports() 
{ 
    $data['tables']=$this->DbReports->selectTable('snehal_pharma'); 
    $this->load->view('reports/rpt.php'); 

} 

型號代碼

function selectTable($db) 
    { 
     $query=$this->db->list_tables(); 
     print_r($query); 
     return $query; 
    } 

查看

<div class="span12"> 
           Table List : 
           <select name="tbl" style="width: 150px;"> 
            <?php foreach($tables->result() as $tbl){ ?> 
            <option><?php echo $tbl;?></option> 
            <?php } ?> 
           </select> 
          </div>

Answer 1

可以訪問像這樣的陣列的鍵：

foreach ($array as $key => $value)

首先檢查var_dump($tables->result())，如何是你的值打印。然後將您的代碼更改爲如下所示。在foreach循環和選擇啓用

<?php foreach($tables->result() as $key => $value){ ?> 

<option value="<?php echo $key;?>"><?php echo $value;?></option> 

<?php } ?> 

Answer 2

使用這些屬性

<?php foreach($tabls as $tbl){ ?> 
    <option><?php echo $tbl;?></option> 
<?php } ?>
