如何在PHP的编辑页面中检查单选按钮？

Question

In php form I get the data from radio button to database. It works well. But in edit page how do I get the checked value from database?

 <td align="left" valign="middle"><input name="signi" type="radio" id="signi" value="S"/> YES
  <input name="signi" type="radio" id="signi" value="N" /> No</td></td>

Answer 1

Do like this in your edit page:

Take database value in variable:

Example:

<?php $signi= $row['signi']; ?> 

And :

<td align="left" valign="middle">
<input name="signi" type="radio" id="signi" value="S" <?php echo ($signi== 'Yes') ?  "checked" : "" ;  ?>/> YES
<input name="signi" type="radio" id="signi" value="N" <?php echo ($signi== 'No') ?  "checked" : "" ;  ?>/> No</td></td>
