问题
How do i do so it show all messages insted of only one, and other problem is that when the user have read there message and this part of the code right below are not showing. The full code can you find at the bottom of the page.
THIS CODE PART ARE NOT SHOWING AFTER A USER HAVE READ THERE NEW MESSAGE, BUT I WILL NOT SHOW:
$newpm = '<div id="notificationTitle">Message</div>
<div id="notificationsBody" class="notifications">You have no new messages</div>';
THE FULL CODE:
$newpm_sql = mysql_query("SELECT * FROM `pm`
WHERE `to` = '". $_SESSION['id'] ."'
ORDER BY `id` DESC") or die(mysql_error());
if (mysql_num_rows($newpm_sql) == 0) {
$newpm = '<div id="notificationTitle">Message</div>
<div id="notificationsBody" class="notifications">You have no new messages</div>';
} else {
while ( $row = mysql_fetch_array( $newpm_sql )) {
$from_sql = mysql_query("SELECT * FROM `members`
WHERE `id` = '". $newpm_sql['from'] ."'")
or die(mysql_error());
$from = mysql_fetch_array($from_sql);
if ($row['status'] == 0) {
$newpm = '<div id="notificationTitle">Message</div>
<div id="notificationsBody" notifications">
<b><a href="page.php?name=profile&id='. $row['from'] .'">'. $row['subject'] .'</a></b><br> '. $row['text'] .'
'</div>';
}
}
}
回答1:
I see the error I missed last time.
This statement
$newpm = '<div id="notificationTitle">Message</div>
<div id="notificationsBody" class="notifications">You have no new messages</div>';
is being run inside a while loop and therefore you should be concatenating these multiple iterations onto $newpm using .= and not just an =
while ( $row = mysql_fetch_array( $newpm_sql )) {
$from_sql = mysql_query("SELECT * FROM `members`
WHERE `id` = '". $newpm_sql['from'] ."'")
or die(mysql_error());
$from = mysql_fetch_array($from_sql);
if ($row['status'] == 0) {
//$newpm = '<div id="notificationTitle">Message</div>
newpm .= '<div id="notificationTitle">Message</div>
<div id="notificationsBody" notifications">
<b>
<a href="page.php?name=profile&id='. $row['from'] .'">'. $row['subject'] .'</a>
</b>
<br> '.
$row['text'] .'
'</div>';
}
}
回答2:
First run this:
SELECT * FROM `pm` WHERE `to` = '<your SESSION ID>'
ORDER BY `id` DESC
and see if that returns something.
You can also do:
var_dump(mysql_num_rows($newpm_sql));die;
after running this mysql_query in first line and see if it returns something you expect.
And also, you can switch to PDO - you will not regret it, as you're now using old php functions.
