  1. I have the following general mySQL query: $query = sprintf( "SELECT a.A, a.B, ..., a.C, FROM a WHERE a.A = %s ORDER by a.A;", implode(" OR a.A = ", $_SESSION['values'])); for some records, B has a value, and for others, B is NULL. That is what I want. I extract the query with the following PHP: for ($i = 0; $i < $nrows; $i++){ $row = mysqli_fetch_assoc($result);//fetches data stored within each row extract($row); echo "<tr>"; foreach($row as $column => $field){ if($field == $...){ ... } elseif($field == $C){ echo"<td> <input type='text' name='C+[]' value='$C'> </td>"; } echo "</tr>" } In the resulting html table, records containing not null B fields are presented accurately, while records with null B fields incur a duplication of field C. This offset occurs at the beginning of the record, pushing the final field in the record outside the table boundaries. I think I've narrowed down the problem to the extract() function, as r_print readouts of every other variable in the script returns the accurate field names and values. But, running print_r on $row after extract() provides an identical printout to other variables in the script. What are some possible ways I can stop the duplication of field C from occurring? Happy to provide more information upon request.
  2. Sorry for the beginner question, here I'm trying to retrieve data from the database and display it in the table format. But only table headers are printed, and not the actual values. The count variable is echoing 2 saying that data is present and correctly retrieved. Can anyone help? <?php include 'connect.php'; error_reporting(E_ALL ^ E_DEPRECATED); error_reporting(E_ERROR | E_PARSE); $sql="SELECT * FROM `resources` as r INNER JOIN `project_resources` as pr ON r.res_id =pr.res_id WHERE project_id='$_POST[project_id]'"; $result=mysql_query($sql); $count=mysql_num_rows($result); if($result === FALSE) { die(mysql_error()); } echo "$count"; echo '<table> <tr> <th>Resource ID</th> <th>Resource Name</th> <th>Email</th> <th>Phone Number</th> <th>Reporting Manager</th> <th>Role</th> <th>Designation</th> </tr>'; while ($row = mysql_fetch_array($result)) { echo ' <tr> <td>'.$row['res_id'].'</td> <td>'.$row['res_name'].'</td> <td>'.$row['email'].'</td> <td>'.$row['phone_number'].'</td> <td>'.$row['reporting_manager'].'</td> <td>'.$row['role'].'</td> <td>'.$row['designation'].'</td> </tr>'; } echo ' </table>'; ?>
