Table not Echoing out if another Table has a Zero value - php

Question

The HTML table below with mysql_query($sqlStr3) (the one with the word "Joined" in its row) does not echo if the result associated with mysql_query($sqlStr1) has a value of zero. This happens even if mysql_query($sqlStr3) returns a result.
In other words, if a given loginid has an entry in the MySQL table "login", but not one in the MySQL table "submission", then the table associated with mysql_query($sqlStr3) does not echo.
I don't understand why the MySQL "submission" table would have any effect on mysql_query($sqlStr3), since the $sqlStr3 only deals with another MySQL table, called "login", as seen below.
Any ideas why this is happening?
Thanks in advance,
John W.

Answer 1

If I understand the problem correctly, you need to echo out $dt3->format('F j, Y') instead of $dt->format('F j, Y') in one of the last lines of the code you have.

Answer 2

while ($row3 = mysql_fetch_array($result3)) {
$dt3 = new DateTime($row3["created"], $tzFrom3);
$dt3->setTimezone($tzTo3);
echo '<tr>';
echo '<td class="sitename5">Joined: '.$dt->format('F j, Y').'</td>';
echo '</tr>';
}
echo "</table>";
Are you looking to call $dt3->format('F j, Y') in the echo here, instead of $->format('F j, Y')? I don't see any other use for $dt3.
