Question

I’m trying to retrieve rows from a mysql table based on variables input by the user. Basically if use wants to search for “bob dilan” $fname and $lname would search and display all rows where this takes place, my connection to the user is fine as my $mysql_num_fields is working perfectly. Currently nothing works inside of my mysql_fetch_rows while loop, not even the echos, but there are no errors. I have even tried using the like operator instead of = to no avail.

PHP

$sql = "SELECT * FROM  ".$tbl_name." 
WHERE fname='".$fname."' 
and lname='".$lname."' 
and city='".$city."'
and phone='".$pohne."'
and interest_inet='".$internet."'
and interest_tv='".$television."'
and interest_voice='".$voice."'
and submission_ip='".$ip."'
and inquiry_handled='".$handled."'";
$result = mysql_query($sql);

echo "<table border='1'>";
echo "<tr>";
$i = 0;

while ($i < mysql_num_fields($result))
{
    $meta = mysql_fetch_field($result, $i);   
    echo "<th>".$meta->name."</th>";
    $i++;
}

while ($row = mysql_fetch_row($result))
{
    echo '<tr>';

foreach($row as $item)
{
    echo "<td>".$item."</td>";
}

echo '</tr>';
echo $row;
}

echo "</table>";

Answer 1

You’re already iterating through the resultset once, which causes the pointer to advance to the end of it.

Complete all of your work in a single loop, or fetch the entire resultset into an array, and iterate it twice.

Other than that, you shouldn’t use mysql_* functions in new code. They are no longer maintained and are officially deprecated. See the red box? Learn about prepared statements instead, and use PDO or MySQLi – this article will help you decide which. If you choose PDO, here is a good tutorial.
