我如何从CodeIgniter中的选择选项获取文本而不是值

Question

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?

Answer 1

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.
