but this, getting categoryid , categoryname array.. how selected textbox value..

i want using php , not javascript / jquery... bit new php... can me / give me suggestion how it...

thanks in advance.

wrap each 1 in own form:

<td>     <form method="post" action="somepage.php">         <input type="text" name="categoryid" value="<?php echo $value['categoryid']?>">         <input type="text" name="categoryname" value="<?php echo $value['categoryname']?>">         <input type="submit" name="create" value="create">     </form> </td> 

since content being posted in case these 2 values, that's entire scope of single form post. each 1 logically/semantically own form. (there's no rule says page can have 1 form. unless you're ever using asp.net webforms, lie.)

note removed id attributes. multiple elements can't have same id, that's invalid html , behavior result becomes undefined.
