I get that error in php..And I have no idea why...
Here is how my connection is established:
<?php
$hostname_QASite = "localhost";
$database_QASite = "qasite";
$username_QASite = "root";
$password_QASite = "";
$QASite = mysql_pconnect($hostname_QASite, $username_QASite, $password_QASite) or trigger_error(mysql_error(),E_USER_ERROR);
?>
my query is the following:
mysql_select_db($database_QASite, $QASite) or die(mysql_error());
$query_get_all_topics = "SELECT topic_id, title FROM topic";
$get_all_topics = mysql_query($query_get_all_topics, $QASite) or die(mysql_error());
$row_get_all_topics = mysql_fetch_assoc($get_all_topics);
$totalRows_get_all_topics = mysql_num_rows($get_all_topics);
And then I iterate over the row_get_all_topics ...
What is wrong in the code ?
Edit:
I get that error, when I try to loop 2 times over different results in the database.

I'm having a bit of an issue with quires failing when I upload to the live environment while they are fully functional in the test environment, I'm at a loss at this point about where the error may be so I finally broke down and decided to ask those of stack overflow that may be much more skilled than myself if there's something I've missed. The quires look at serial number information from two different tables to pull system specs and any hard drive information associated with the parent serial

I want to generate HTML table into PDF.
But I'm having trouble for gridding the table. I want to generate table like this:
I have this table from database:
Which is should fill this column:
and I have a second table from database like this:
which is should fill the rest of the columns except keterangan column.
I tried this code :
<table class="tbl" border="1" style="margin: 0 auto;">
<tr style="height: 50px;">
<th rowspan="2" style="width: 50%">Nomor</th>
<th colspan="4">Pemberian entertaiment dan sejenisnya</th>
<th colspan="4">Relasi usaha yang diberikan entertainment dan sejenisnya</th>
<th rowspan="2">Keterangan</th>
</tr>
<tr>
<th>Tanggal</th>
<th>Alamat</th>
<th>Jenis</th>
<th>Jumlah</th>
<th>Nama</th>
<th>Posisi</th>
<th>Nama Perusahaan</th>
<th>Jenis Usaha</th>
</tr>
<tr>
<td>
<?PHP echo $row->nomor?>
</td>
<td>
<?PHP echo $row->tanggal?>
</td>
<td>
<?php echo $row->alamat?>
</td>
<td>
<?PHP echo $row->jenis?>
</td>
<td>
<?PHP echo $row->jumlah?>
</td>
<?php
foreach ($list->result() as $data){
?>
<tr>
<td>
<?PHP echo $data->nama?>
</td>
<td>
<?PHP echo $data->posisi?>
</td>
<td>
<?PHP echo $data->nama_perusahan?>
</td>
<td>
<?PHP echo $data->jenis_usaha?>
</td>
</tr>
<?php
}
?>
<td>
<?PHP echo $row->keterangan?>
</td>
</tr>
but this is the result :
Try this:
<table class="tbl" border="1" style="margin: 0 auto;">
<tr style="height: 50px;">
<th rowspan="2" style="width: 50%">Nomor</th>
<th colspan="4">Pemberian entertaiment dan sejenisnya</th>
<th colspan="4">Relasi usaha yang diberikan entertainment dan sejenisnya</th>
<th rowspan="2">Keterangan</th>
</tr>
<tr>
<th>Tanggal</th>
<th>Alamat</th>
<th>Jenis</th>
<th>Jumlah</th>
<th>Nama</th>
<th>Posisi</th>
<th>Nama Perusahaan</th>
<th>Jenis Usaha</th>
</tr>
<tr>
<td>
<?PHP echo $row->nomor?>
</td>
<td>
<?PHP echo $row->tanggal?>
</td>
<td>
<?php echo $row->alamat?>
</td>
<td>
<?PHP echo $row->jenis?>
</td>
<td>
<?PHP echo $row->jumlah?>
</td>
<?php
foreach ($list->result() as $data){
?>
<tr>
<td> </td>
<td> </td>
<td> </td>
<td> </td>
<td> </td>
<td>
<?PHP echo $data->nama?>
</td>
<td>
<?PHP echo $data->posisi?>

<?PHP echo $data->jenis_usaha?>
</td>

<?php
}
?>
<td>
<?PHP echo $row->keterangan?>
</td>
</tr>
Note the extra columns are added inside the loop to enable it to line up with you headers.
This is the code, and as written in the title, I'm trying to have each column with the same width:
<div class="table-responsive">
<table class="table table-striped table-hover">
<thead>
<tr>
<th>N°</th>
<th>Data</th>
<th>Compratore</th>
<th>Venditore</th>
<th>Merce</th>
<th>Quantita'</th>
<th>Prezzo</th>
<th>Pagamento</th>
<th>Azioni</th>
</tr>
</thead>
<tbody>
<?php
$result = query("SELECT numero_contratto, anno_contratto, data, C.denominazione as compratore, V.denominazione as venditore, merce, quantita, info_quantita, prezzo, info_prezzo, pagamento FROM Contratti, Societa V, Societa C WHERE compratore = C.id_societa and venditore = V.id_societa ORDER BY data DESC", $conn);
foreach($result as $r)
{
?>
<tr>
<td>
<?php echo $r['numero_contratto']."/".$r['anno_contratto']; ?>
</td>
<td>
<?php
$data = explode("-", $r['data']);
echo $data[2]."-".$data[1]."-".$data[0];
?>
</td>
<td>
<?php echo $r['compratore']; ?>
</td>
<td>
<?php echo $r['venditore']; ?>
</td>
<td>
<?php echo $r['merce']; ?>
</td>
<td>
<?php echo $r['quantita']." ".$r['info_quantita']; ?>
</td>
<td>
<?php echo $r['prezzo']." ".$r['info_prezzo']; ?>
</td>
<td>
<?php echo $r['pagamento']; ?>
</td>
<td>
<span class="glyphicon glyphicon-remove"></span>
</td>
</tr>
<?php
}
?>
</tbody>
</table>
</div>
And this is the output on my web page:
But if you see this Fiddle with static values putted into the table, the problem doesn't show!
http://jsfiddle.net/brVa9/1/
So the problem is inside the db schema or structure.
What I should do to have all the columns with the same width?
i am constructing a registration page for new members. after filling in the form, it will proceed to the confirm page. after confirmation, it will proceed to the reg_add.php to add the data from the form to the database.
reg_new.php --> reg_confirm.php --> reg_add.php
i am trying to edit the code in the confirm page (reg_confirm.php) to include the email availability check. it seems that it can automatically detect the duplicate email and after clicking the confirm button.
Duplicate entry 'shop#gmail.com' for key 'PRIMARY' will be shown.
yet, it is not success to have a pop up alert and stay in the confirm page. please help.

Your problem is how you are retrieving the number of rows from the database.
mysql_query() does not retrieve the number of rows. It retrieves a result set.
Instead of:
$numrows = mysql_query("SELECT membermail FROM member WHERE memberemail='$regemail'");
if ($numrows!=0)
{
echo "<script>alert('Email has been used by others!');window.location.href= 'reg_new.php';</script>";
}
Use:
$email = mysql_real_escape_string($_POST["email_reg"]);
$result = mysql_query("SELECT COUNT(memberemail) AS emailCount FROM member WHERE memberemail='{$email}'");
$row = mysql_fetch_row($result);
if($row[0]>0){
echo "<script>alert('Email has been used by others!');window.location.href= 'reg_new.php';</script>";
}
ALWAYS make sure you escape your data before using it in a database query.

You have to use while() loop for iterating all possible answers.
