To do what you're suggesting, you'd have to put each line of HTML in
separate ECHO statements (see below). The problem with this approach is
that the table will eventually contain very complex code in each cell. I'd
have to do extensive escaping to make sure the code is correctly
interpreted.
I used a shortcut syntax that allows you to embed several lines of HTML in
an IF statement without having to escape everything. The short PHP
statement after the embedded lines tells PHP that the embedded code is
embedded as if it was ECHOed line by line. This works most of the time.
Just not in this instance.
To use your suggestion, the code would have to look like this...
<?php
if ($row_RS_PageContent['PageType'] != "2") {
echo '<tr>';
echo '<td width=\"200\" height=\"0\" bgcolor=\"99CCCC\"> </td>';
echo '<td width=\"20\" height=\"0\"> </td>';
echo '<td height=\"0\" align=\"left\" valign=\"top\"> </td>';
etc.
}
?>
Note all of the escaping required to simply define the table. You'd have
tons more to do when images, links, JavaScript calls, etc. are placed in
the table.
