    <?php   # init mysql connection   mysql_connect("localhost", "root", "") or die(mysql_error()) ;   mysql_select_db("selfie") or die(mysql_error()) ;    # prepare select query   $selectsql = 'select * `image_upload`  inner join user_table on image_upload.user_id=user_table.user_id flag="0" order timestamp desc';  # execute select query   if( !( $selectres = mysql_query( $selectsql ) ) ){     echo 'retrieval of data database failed - #'.mysql_errno().': '.mysql_error();    }else{     ?> <table border="2">    <thead id="head">     <tr>       <th id="head">user name</th>       <th>category</th>       <th>description</th>       <th>image</th>       <th>location</th>       <th>status</th>     </tr>   </thead>   <tbody>     <?php      if (isset($_get['submit'])) {                          $mobile = $_get['dmobile'];                          $query = mysql_query("update image_upload set   flag='$mobile' " );                     }                      if (isset($_get['submit'])) {                    header("location: imagemanagement.php");                    }         if( mysql_num_rows( $selectres )==0 ){         echo '<tr><td colspan="4">no rows returned</td></tr>';       }else{         while( $row = mysql_fetch_assoc( $selectres ) ){           echo "<tr>              <td>{$row['user_name']}</td>              <td>{$row['category']}</td>              <td>{$row['description']}</td>              <td ><img src='uploads/".$row['image']."'width=300px height=200px></td>              <td>{$row['location']}</td>              <td><form class=\"form\" method=\"get\"><label></label><br/>              <input class=\"input\" type=\"text\" name=\"dmobile\" value=\"    {$row['flag']}\" />            <br>            <input class=\"submit\" type=\"submit\" name=\"submit\" value=\"update\" />           </form></td>           </tr>\n";             }       }     ?>   </tbody> </table>     <?php

in here when changes , click on submit button of 1 row each , every rows updated. how can give unique value each , every submit button.

comment answer, since op said works.

op: "it's work. thank much.... :) – lanka"

add form:

<input type=\"hidden\" name=\"the_id\" value=\"{$row['id']}\" />

then add: 

$theid = $_post['the_id'];

then, 

$query = mysql_query("update image_upload set flag='$mobile'   id = '$theid' " );

you may need play around bit, in hidden input is.

this based on having "id" column of course.

n.b.:

  • you should validate user input (even if it's hidden field)

use mysqli prepared statements, or pdo prepared statements, they're safer.

as stands, using deprecated mysql library, leaves open sql injection.
