我如何从CodeIgniter中的选择选项获取文本而不是值

问题描述：

I have a form in which there is a select field with many options. These options have numeric values and a text between option tags. What I want to do is to get the text instead of values when I post the form via submit button.

View that generates the select field:

echo form_dropdown('pos', $pos_options, '100', 'id="pos_select" class="form_input"');

the select part generated:

<select name="pos" id="pos_select" class="form_input">
    <option value="0">about_history_title</option>
    <option vlaue="1">about_history</option>
</select>

When the form is submited, the appropriate model is called via the controller(text.php):

text.php -> insert_text()

$this->admin_text_model->insert_text();

admin_text_model.php

public function insert_text()
{
    $data = array(
        'tx_page' => $this->input->post('page'),
        'tx_pos' => $this->input->post('pos'),
        'tx_body' => $this->input->post('add_text')
    );

    return $this->db->insert('text', $data);
}

Is there a way that I can get the text inside option tags in $this->input->post('pos')?

Perhaps something like:

'tx_pos' => $this->input->post('pos')->text?

我有一个表单，其中有一个包含许多选项的select字段。这些选项具有数值和选项标记之间的文本。我想要做的是在通过提交按钮发布表单时获取文本而不是值。 p>

生成选择字段的视图： p>

  echo form_dropdown（'pos'，$ pos_options，'100'，'id =“pos_select”class =“form_input”'）;  
  code>  pre> 
 
 生成的选择部分： p> 
 
 
 ＆lt; select name =“pos”id =“pos_select”class  =“form_input”＆gt; 
＆lt; option value =“0”＆gt; about_history_title＆lt; / option＆gt; 
＆lt; option vlaue =“1”＆gt; about_history＆lt; / option＆gt; 
＆lt; / select＆gt; 
  代码>  pre> 
 
 当表单被提交时，通过控制器调用相应的模型（text.php）： p> 
 
 
 text.php  - ＆gt;  insert_text（） P> 
 
 
  $这 - ＆GT; admin_text_model-＆GT; insert_text（）; 
 代码>  PRE> 
 
  admin_text_model.php   p> 
 
 
  public function insert_text（）
 {
 $ data = array（
'tx_page'=＆gt; $ this-＆gt; input-＆gt; post（'page  '），
'tx_pos'=＆gt; $ this-＆gt; input-＆gt; post（'pos'），
'tx_body'=＆gt; $ this-＆gt; input-＆gt; post（'add_text'）  
）; 
 
返回$ this-＆gt; db-＆gt; insert（'text'，$ data）; 
} 
  code>  pre> 
 
 是否有 我可以在$ this-＆gt; input-＆gt; post（'pos'）中的选项标签内获取文字的方式？ p> 
 
 
也许类似于： p> 
 \  n 
 'tx_pos'=＆gt;  $ this-＆gt; input-＆gt; post（'pos'） - ＆gt; text？
  code>  pre> 
  div>

答

Try this don't assign the value to option tag:

<select name="pos" id="pos_select" class="form_input">
    <option>about_history_title</option>
    <option>about_history</option>
</select>

It will return text of option.

答

No, text inside <option> tags is never submitted. That is just how HTML works.

You must set the values, that you need to retrieve, in the value attribute. That is what they are for.

答

You could make the select yourself and not using the CI helper. This way you have full control on what and where to output it:

<select name="pos" id="pos_select" class="form_input">
  <?php foreach($pos_options as $option):?>
    <option value="<?php echo htmlentities($option);?>"><?php echo $option;?></option>
  <?php endforeach;?>
</select>

Or, you could make an ugly hack in javascript:

$('#pos_select option').each(function(){
   $(this).attr('value', $(this).text()); 
});

Which sets the value of every option equal to its text content: http://jsfiddle.net/ursQY/
