php if statement not sure how to do 2 if's - php

Question

I'm trying to do a condition within an if statement.
I have a current if statement which determines odd and even for css styling.
Within this I want to add another if statement for the reference number. (outlined as Ref in the code).
I'm not sure how to go about this but I want to add something along the lines of
if ref == 1 then echo ref, I've tried putting an if within an if and I just keep getting syntax errors. Can someone point me in the right direction please?
include "db_connect.php";
$result1 = mysql_query("SELECT * FROM updates ORDER BY id DESC limit 5");
$result2 = mysql_num_rows($result1);
$x = $result2;
while ($row1 = mysql_fetch_array($result1)) {
if (++$x % 2) {
echo "<blockquote class='example-right'>" . $row1['update'] .
"<div class='ref'>Ref: " . $row1['ref'] .
"</div><div class='date-right'> from " . $row1['date'] .
" to " . $row1['todate'] .
"</div> </blockquote> <p>" . $row1['username'] .
"</p> </td>";
echo "</p>";
} else {
echo "<blockquote class='example-obtuse'>" . $row1['update'] .
"<div class='ref'>Ref: " . $row1['ref'] .
"</div><div class='date-right'> from " . $row1['date'] .
" to " . $row1['todate'] .
"</div> </blockquote> <p>" . $row1['username'] .
"</p> </td>";
}
}
the bit I tried to do with 2nd if statement:
include "db_connect.php";
$result1 = mysql_query("SELECT * FROM updates1 ORDER BY id DESC limit 5");
$result2 = mysql_num_rows($result1);
$x = $result2;
while ($row1 = mysql_fetch_array($result1)) {
if (++$x % 2) {
$sch = $row1['schuedled'];
else if ($sch == '1') {
echo "<blockquote class='example-right'>" . $row1['update'] .
"<div class='ref'>Ref: " .$row1['ref'] .
"</div><div class='date-right'> from " . $row1['date'] .
" to " . $row1['todate'] .
"</div> </blockquote> <p>" . $row1['username'] .
"</p> </td>";
else {
echo "<blockquote class='example-right'>" . $row1['update'] .
"</div><div class='date-right'> from " . $row1['date'] .
" to " . $row1['todate'] .
"</div> </blockquote> <p>" . $row1['username'] .
"</p> </td>";
}
}
echo "</p>";
} else {
echo "<blockquote class='example-obtuse'>" . $row1['update'] .
"<div class='assyst-ref'>Ref: " . $row1['ref'] .
"</div><div class='date-right'> from " . $row1['date'] .
" to " . $row1['todate'] .
"</div> </blockquote> <p>" . $row1['username'] .
"</p> </td>";
}
}

Answer 1

Try something like this:
while($row1 = mysql_fetch_array($result1)){
$html = '';
if (++$x % 2 ){
$html .= "<blockquote class='example-right'>";
} else {
$html .= "<blockquote class='example-obtuse'>";
}
$html .= $row1['update'];
if($row1['schuedled'] == '1'){
$html .= "<div class='ref'>Ref: " .$row1['ref'] . "</div>";
}
$html .= "more html";
$html .= "more html";
$html .= "more html";
$html .= "</blockquote>";
echo $html;
}
