Using foreach to display results - php

Question

I'm trying to write some sort of forum homepage, based off work someone else did. Here's what I've got so far:
Forums
<?php
$crumbs = explode(",", $user['data']['depts']);
foreach ($crumbs as &$value) {
$data = $db->query("SELECT * FROM tbl_depts WHERE id = '" . $value . "'");
$crumb = $data->fetch_assoc();
$data = $db->query("SELECT * FROM tbl_forums WHERE deptid = '" . $value . "'");
$forumcount = $data->num_rows;
$forum = $data->fetch_assoc();
?>
<div class="h3top"><?php echo $crumb['name']; ?></div>
<div class="info2alt">
<?php
while (($row = $data->fetch_array()) !== FALSE) {
$forum[] = $row;
}
foreach ($forum as $row) {
if ($forumcount >= 1) {
if ($forum['lastpost'] == "") {
$forum['lastpost'] = "--";
}
?>
<div class="info4">
<table width="100%" border="0" cellspacing="1" cellpadding="4">
<tr>
<td width="55%" align="left" valign="middle" class="zebraodd"><?php echo $row['name']; ?></td>
<td width="10%">Threads: <?php echo $forum['threadcount']; ?><br />Posts: <?php echo $forum['postcount']; ?></td>
<td width="35%">Last Post: <?php echo $forum['lastpost']; ?></td>
</tr>
</table>
</div>
<?php
}
?>
<?php if ($forumcount >= 1) { ?>
<div class="info3bottom"></div>
<?php
}
}
?>
</div>
<?php
}
?>
This is the current data in the table:
Now, when I try to use this code, I get this:, such that the first one is shown so many times, however, the next one does not appear.
How do I fix this?

Answer 1

you want to use $value['threadcount'] etc. $forum is the array containing all the rows. i wonder that you get some output at all …
fetch_assoc() will only fetch a single row from the resultset. you'd have to use a loop to fill an array:
while(($row = $data->fetch_assoc()) !== FALSE) {
$forum[] = $row;
}
you can then iterate over your $forum array with a foreach loop:
foreach($forum as $row) {
echo htmlspecialchars($row['threadcount']);
// etc.
}
trying to fix this mess …
<?php
$crumbs = explode(",", $user['data']['depts']);
foreach ($crumbs as $crumb) { ?>
<div class="h3top"><?php echo htmlspecialchars($crumb['name']);?></div>
<?
}
$result = $db->query("SELECT * FROM tbl_forums WHERE deptid = " . (int)$id . "");
$forumcount = $result->num_rows;
while(($row = $data->fetch_assoc()) !== FALSE) {
if ($row['lastpost'] == "") { $row['lastpost'] = "--";}
?>
<div class="info2alt">
<div class="info4">
<table width="100%" border="0" cellspacing="1" cellpadding="4">
<tr>
<td width="55%" align="left" valign="middle" class="zebraodd"><?php echo htmlspecialchars($forum['name']); ?></td>
<td width="10%">Threads: <?php echo htmlspecialchars($forum['threadcount']); ?><br />Posts: <?php echo htmlspecialchars($forum['postcount']); ?></td>
<td width="35%">Last Post: <?php echo htmlspecialchars($forum['lastpost']); ?></td>
</tr>
</table>
</div>
<div class="info3bottom"></div>
<?php
}
?>
