mysql - HTML Form button in PHP While loop -

-

i have while loop in php selects data database

i want have complete button each row returned which, when pressed run sql query change value of status column of particular row

my while loop is:

$stmt = $pdo_conn->prepare("select * messages status = :status , (assigned_to = :assigned_to1 or assigned_to = :assigned_to2) "); $stmt->execute(array(':status' => '', ':assigned_to1' => $user_result["sequence"], ':assigned_to2' => '')); $records = $stmt->fetchall(pdo::fetch_assoc); $i=0; if(count($records) > 0) {     echo '<tr>     <td colspan="7">you have '.count($records).' messages</td>     </tr>';     foreach($records $messages) {         $i++;         echo '<tr>         <td>'.adminnamelookup($messages["assigned_to"]).'</td>         <td>'.$messages["caller_company"].'</td>         <td>'.$messages["caller_telephone"].'</td>         <td>'.$messages["caller_email"].'</td>         <td>'.$messages["caller_message"].'</td>         <td><input type="submit" name="completemessages['.$i.']" value="" /></td>         </tr>';     } }

but i'm not sure on how handle php on submit?

before sending data need create html form tag. , have pass values using input tag values.

format tag should below code.

 <form action="" method="">  <input  type="" value="">  <input type="submit" name="completemessages['.$i.']" value="" />  </form>
