<p>So, I have a checkbox that allows the user to select the columns they want to view. So, if the user wants for example to select only 2 columns (say, TicketID and Category) it will only show the data of the ID and the category of the ticket. Here's what I have so far:</p> <p>form:</p> <pre><code> <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post"> <ul> <li><input type="checkbox" name="filter[]" value="TicketID" >Ticket ID</li> <li><input type="checkbox" name="filter[]" value="Category" />Category</li> <li><input type="checkbox" name="filter[]" value="Priority" />Priority</li> <li><input type="checkbox" name="filter[]" value="Status" />Status</li> <li><input type="checkbox" name="filter[]" value="InitialDescription" />Initial Description</li> <li><input type="checkbox" name="filter[]" value="SubmittedDate" />Submitted Date</li> <li><input type="checkbox" name="filter[]" value="Description" />Status Description</li> <input type="submit" value="Refresh Filters"> </ul> </form> </td> <td> <?php viewTicketTable($_SESSION['userID'],$_POST['filter']); ?> </code></pre> <p>viewticketTable function:</p> <pre><code>function viewTicketTable($userID,$columns) { /* Accepts $userID which will identify the tickets related with the user and $columns which will filter only the columns that are required and outputs the table with the columns passed through. */ /* $columns_array = explode(',', $columns); foreach($array as $array){ echo $array; } */ foreach($columns as $filter) { $filter = $filter . ',' ; } $filter = substr($filter, 0, -1); $query = mysql_query(" SELECT $filter FROM Ticket LEFT JOIN TicketHistory ON Ticket.TicketID = TicketHistory.TicketID WHERE CustomerID = $userID; "); /* Creation of the table */ echo ' <table border="1"> <thead> <tr>'; foreach($columns as $tableHeader) { $tableHeader = '<th scope="col">' . $tableHeader . '</th>' ; echo $tableHeader; } echo ' </tr> </thead> <tbody> '; /*Looping through the script to print out all the information.*/ while ($row = mysql_fetch_array($query) or die(mysql_error())) { echo ' <tr>'; foreach($columns as $field) { echo '<td>' . $row[$field] . '</td>'; } echo '</tr> '; } echo ' </tbody> </table>'; </code></pre> <p>}</p> <p>The problem resides in the while loop. row[$field] is only populating the last column instead of populating all of them. Any help?</p>

1. COBefore anything else; you need to do something to harden your query against SQL injection. Right now anyone with enough chops to use a browser to inspect and edit your page could change one of the filter input values to something malicious.

Querying!

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
