使用HTML表单将Smarty变量传递给php文件。

Question

I have this form inside a Smarty template file :

<form method="post" action="manswer.php">
        <table border="0" cellpadding="5" cellspacing="0" >
            <tr>
                <td style = "vertical-align:top;">Answer:</td>
                <td><textarea rows="8" cols="50" name='answer_text' ></textarea></td>
            <tr>
                <td><br/></td>
                <td><input  id = 'answerbutton' type='submit'  value='Cevapla!' /></td>
            </tr>
            </tr>
        </table>
</form>

I also have {$q_id} variable inside that template file. How can I pass this variable to manswer.php with that HTML form? Thanks.

Answer 1

使用隐藏字段。

<input type="hidden" value="{$q_id}" name="something" />

Answer 2

Using a hidden input field.

<input type="hidden" value="<?php echo $q_id;?>" name="something" />

Then to retrieve it using CodeIgniter

...
$something = $this->input->post('something');
