    <p>I am writing a switch statement in php which will determine what a mysql query will be based on posted data. The amount data that is posted varies based on the database, which creates the form. Is there any way that I can have the possible cases pull from the database because the same code is executed for all of them with some case specific modifications. The reason I don't just use one possibility instead of the switch is because there are other non database related cases that can feed into the switch. </p> <p>This may clear things up</p> <p>I have 2 pages people.php and edit.php. people.php dynamically creates a table of members in a building based on the building Id which is sent via get. From this table a user can select what they would like to change about the records from a drop down menu and then the script posts everything to edit.php. If a user wishes to change someone's building then the switch case catches thais and creates a form to ask which building they will be changed to. This then posts back to edit.php. Do I have to hard code each building into the switch or can I make it dynamically create cases based on the available buildings from mysql?</p> <p><code>echo"&lt;td&gt;&lt;select name='action'&gt; &lt;option value='save' selected='yes'&gt;Save Changes&lt;/option&gt; &lt;option value='delete'&gt;Delete Record&lt;/option&gt; &lt;option value='more'&gt;Add Additional Phone Numbers and or Email Addresses&lt;/option&gt; &lt;option value='building'&gt;Change This person's Building&lt;/option&gt; &lt;/select&gt;&lt;/td&gt;"</code></p> <p>this is created in every row of the table of people which will determine what the form will do with the data in edit.php</p> <pre><code>switch ($_POST['action']) { case 'save': update($_POST); header("Location: people.php?bid=".$_POST['bid']); break; case 'delete': //Havent written delete person code yet break; case 'more': //havent written add more phone number or emails yet break; case 'building': echo "Move ".$_POST['fname']." ".$_POST['mname']." ".$_POST['lname']." to which building? &lt;br/&gt;&lt;form action='edit.php' method='POST'&gt;&lt;select name='action'&gt;" compile_permissions($_SESSION['uid']); foreach($_SESSION['buildings'] as $value) { $query="select name from schools where bid='$value'"; $result=mysql_query($query); $row=mysql_fetch_array($result); echo "&lt;option value='$value'&gt; Move to ".$row['name']."&lt;/option&gt;"; } echo "&lt;/select&gt;&lt;br/&gt;&lt;input type='submit' value='Go'&gt;&lt;/form&gt;" break; default: header("Location:index.php"); break; } </code></pre> <p>I Need to pass the pid and the bid to edit.php with this form so I can use a query to update their building how can I go about doing this?</p>

    3. COOne thing is certain: PHP doesn't really support the kind of meta-programming necessary to "dynamically create `switch` cases". But that's not really necessary either, you'll probably just need to use a loop to go through your cases pulled from the database instead.

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.
