list_writings(poetry); or more accurately std_layout("Recent Writings",
list_writings(poetry)); I've also tried that using various methods of
quoting for the list_writings(poetry) and also doing strange things like
making anonymous functions and defining the function as a variable and
what-not.

list_writings(poetry) simply spits out the output. 'echo
list_writings(poetry)' was not designed as the proper way to use the
command. Here is the current code for the function (in its half-complete but
working state with mysql_connect() and mysql_select_db replaced with generic
variables for public consumption), and also the std_layout function
following:
function list_writings($table) {
$db_link = mysql_connect($host, $user, $pw)
or die("DB connect failure");
mysql_select_db ($db_name) ;
$query = "SELECT wid, title, description FROM $table ORDER BY wid DESC LIMIT
15";
$result = mysql_query($query, $db_link);
while ($row = mysql_fetch_row ($result))
{
print "<a
href=\"/poetry.php?wid=$row[0]\">$row[1]</a><br>";
};
};
function std_layout($ltitle, $ltext) {
echo "
<table width=\"100%\" align=\"top\">
<tr>
<td valign=\"top\">
<table style=\"border-top: 1px solid #000000; border-right: 1px solid
#000000\" width=\"175\">
<tr>
<td bgcolor=#B0C4DE valign=\"top\">
$ltitle
</td>
</tr>
<tr>
<td>
$ltext
</td>
</tr>
</table>
</td>
<td valign=\"top\">" ;
} ;
Basically, I want std_layout to be able to take either straight text as an
argument or the output of a function (even if it's through a mid-point such
as a variable). That failing I'm going to have to admit a design flaw to
myself and re-work the code...
