Help with PHP While function - php

Question

Why is this not working?
<?php
$select = "select * from messages where user='$u'";
$query = mysqli_query($connect,$select) or die(mysqli_error($connect));
$row = mysqli_num_rows($query);
$result = mysqli_fetch_assoc($query);
$title = mysqli_real_escape_string($connect,trim($result['title']));
$message = mysqli_real_escape_string($connect,trim($result['message']));
while(($result = mysqli_fetch_assoc($query))){
echo $title;
echo '<br/>';
echo '<br/>';
echo $message;
}
?>
where as this works -
<?php
echo $title;
?>
SORRY TO SAY, BUT NONE OF THE ANSWERS WORK. ANY OTHER IDEAS?

Answer 1

If your mysqli query is returning zero rows then you will never see anything printed in your while loop. If $title and $message are not set (because you would want reference them by $result['title'] & $result['message'] if that are the field names in the database) then you will only see two <br /> tags in your pages source code.

Answer 2

If the while loop conditional is not true then the contents of the while loop will never execute.
So if there is nothing to fetch from the query, then you won't see any output.

Answer 3

Does you code display anything, or skip the output entirely?
If it skips entirely, then your query has returned 0 rows.
If it outputs the <br /> s, then you need to check your variables. I could be wrong, not knowing te entire code, but generally in this case you would have something like
echo $result['title'] instead of echo $title

Answer 4

If $title and $message come from your mysql query then you have to access them through the $result array returned by mysqli_fetch_assoc.
echo $result['title'];
echo $result['message'];

Answer 5

Also if your using mysqli you'd be doing something like this:
$mysqli = new mysqli("localhost", "user", "password", "db");
if ($result = $mysqli->query($query)) {
while ($row = $result->fetch_assoc()) {
print $row['title'];
}
$result->close();
}

Answer 6

Try this:
<?php
$result = mysql_query($query);
while($row = mysqli_fetch_assoc($result)){
echo $title.'<br/><br/>'.$message;
}
?>

Answer 7

Does this work;
<?php
$select = "select * from messages where user='$u'";
$query = mysqli_query($connect,$select) or die(mysqli_error($connect));
$row = mysqli_num_rows($query);
while(($result = mysqli_fetch_assoc($query))){
echo $result['title'];
echo '<br/>';
echo '<br/>';
echo $result['message'];
}
?>
Basically I've made sure that it's not picking the first result from the query & then relying on there being more results to loop through in order to print the same message repeatedly.
