Closed 7 years ago.
I've been working on a project that prints sql data into a table. Recently, I've come into a problem with the table. What this code should do is output a table of results from a MySQL query but all it's outputting is something like:
Item1 Item1
For some reason it leaves all the other fields blank. Here's my code:
$table = "<table class='TestTable'><tr class='tr'>";
while($row = mysql_fetch_assoc($result)){
$table .= "<th class='th'>";
$table .= $row['NameOfItem'];
$table .= "</th>";
}
$table .= "</tr><tr class='tr'>";
while ($row = mysql_fetch_assoc($result)){
$table .= "
<td class='td'>Minimum Bid: <b>";
$table .= $row['MinBid'];
$table .= "</b></td>";
}
$table .= "</tr><tr class='tr'>";
while ($row = mysql_fetch_assoc($result)){
$table .= "<td class='td'>Current Bid: <b>";
$table .= $row['CurrentBid'];
$table .= "</b></td>";
}
$table .= "</tr><tr class='tr'>";
while ($row = mysql_fetch_assoc($result)){
$table .= "<td class='td'>Sold By: <b>";
$table .= $row['SoldBy'];
$table .= "</b></td>";
}
$table .= "</tr><tr class='tr'>";
while ($row = mysql_fetch_assoc($result)){
$table .= "<td class='td'>Time Left: <b>";
$table .= printf('%d days, %d hours, %d minutes left', $diff->d, $diff->h, $diff->i);
$table .= "</b></td>";
}
$table .= "</tr></table>";
echo $table;
When I view source I get:
<table class='TestTable'>
<tr class='tr'>
<th class='th'>Item1</th>
<th class='th'>Item1</th>
</tr>
<tr class='tr'></tr>
<tr class='tr'></tr>
<tr class='tr'></tr>
<tr class='tr'></tr>
</table>

Answer 1

After while($row = mysql_fetch_assoc($result)) {...} you have reached the end of your result set. You have to rewind the result pointer to the beginning of the result set if you want to read it again. Do this by using
while($row = mysql_fetch_assoc($result)){ ... }
mysql_data_seek($result, 0); // Rewind result pointer
while($row = mysql_fetch_assoc($result)){ ... }
mysql_data_seek($result, 0); // Rewind result pointer
while($row = mysql_fetch_assoc($result)){ ... }

Answer 2

First get your results and safe them in an array:
while($r = mysql_fetch_assoc($result)){
$row[] = $r;
}
Then reuse the array as often as needed to build the table like this:
$table .= "</tr><tr class='tr'>";
foreach ($row as $r){
$table .= "
<td class='td'>Minimum Bid: <b>";
$table .= $r['MinBid'];
$table .= "</b></td>";
}
... and yes, mysql-functions are deprecated. When you move to PHP7 they'll be gone. Use PDO or mysqli instead.
