    <p>I have the following code. I am trying to handle two form posts with in the same page. What the code is doing is whenever a user clicks "next14days" button, it display the data for the next 14 days and If the user clicks "prev14days" it should display the data of the previouse 14 days. This for me is not working. </p> <p>for example lets say current date is 2011/01/03 and I hit next14days the current date should be 2011/01/17. This works but when I hit prev14days which should take me back to 2011/01/03, it is going to 2010/12/20 which looks like (2011/01/03 - 14).</p> <p>the page refreshes every time a user hits one of the buttons and anything inside the IF clause is not accessible either way.</p> <pre><code>&lt;?php if(($prevFlag == '' || $nextFlag == '')) { $currentDay = date('Y/m/d'); $SQL4 = "Exec EmployeeVac '" . $currentDay . "'"; $result4 = mssql_query($SQL4,$link1) or die('An error occured: ' . mssql_get_last_message()); } if (isset($_POST['next14submit'])) { $nextFlag = 'yes'; if($prevFlag == 'yes') { $next14 = date('Y/m/d', strtotime($prev14 . "+14 days")); $currentDay = $next14; $SQL4 = "Exec EmployeeVac '" . $currentDay . "'"; $result4 = mssql_query($SQL4,$link1) or die('An error occured: ' . mssql_get_last_message()); } else { $next14 = date('Y/m/d', strtotime($currentDay . "+14 days")); $currentDay = $next14; $SQL4 = "Exec EmployeeVac '" . $currentDay . "'"; $result4 = mssql_query($SQL4,$link1) or die('An error occured: ' . mssql_get_last_message()); } } if (isset($_POST['prev14submit'])) { $prevFlag = 'yes'; echo $nextFlag; if($nextFlag == 'yes') { $prev14 = date('Y/m/d', strtotime($next14 . "-14 days")); $currentDay = $prev14; $SQL4 = "Exec EmployeeVac '" . $currentDay . "'"; $result4 = mssql_query($SQL4,$link1) or die('An error occured: ' . mssql_get_last_message()); } else { $prev14 = date('Y/m/d', strtotime($currentDay . "-14 days")); $currentDay = $prev14; $SQL4 = "Exec EmployeeVac '" . $currentDay . "'"; $result4 = mssql_query($SQL4,$link1) or die('An error occured: ' . mssql_get_last_message()); } } ?&gt; </code></pre>

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.
