Question

I have created a while loop

while($row = mysql_fetch_Array($result)) { 
  echo '<tr class="record"> <td></td><td>'
     . $row['company'] .'</td><td>'
     . $row['project'].'</td><td>'
     . $row['assignee']. '</td><td>'
     . $row['current_milestone'] . '</td><td>'
     . $date=date("d-m-Y", strtotime($row['start_date'])).'</td><td>' ..'</td><td>'
     . $row['next_milestone'] . '</td><td>'
     .   $date=date("d-m-Y", strtotime($row['next_date']))
     .'</td></tr>' ; 
}

This displays correctly but my question is:

How can the user select an individual row so he/she can edit it. I was hoping that the user can select which row they wanted and they would be taken to another screen where they can make the changes. I can figure out how to do the part where I can update the data. But it is the selecting the row and collecting correct data I dont understand how to do.

Answer 1

Embed an <a href='update.php?id=> somewhere in there which carries the record id to the update script as a parameter in the query string:

while($row = mysql_fetch_Array($result)) { 
  echo '<tr class="record"> <td></td><td>'
     // Insert a link with an id parameter.
     // Use whatever column value uniquely identifies your row
     . '<a href="update.php?id=' . $row['id'] . '"> Edit this! </a>' 
     // etc... 
     // etc...
     // etc...
     .'</td></tr>' ; 
}

And retrieve it on the update script via:

// Assuming an integer id was passed...
// if it is some other string value, escape and quote it accordingly.
$id = intval($_GET['id']);

And you will want to check that the user making the edit has permission to edit that record. In other words, verify that the record is owned by the user is logged in, since anyone could technically visit the URL with any id, whether or not it belongs to them. As in:

UPDATE yourtable SET col1 = 'whatever', col2 = 'whatever' WHERE id = $id AND user_id = 'logged_in_user'
