eval() problem?

[4ebura6ka]

Hello,

I've a table "prices" (id, price1, price2, price3, price4, price5, price6). I select values from this table:

$query = "SELECT id, price1, price2, price3, price4, price5, price6 FROM prices";
$result = mysql_query($query);

The problem begins when I start output table values:

if ($result)
{
    $row = mysql_fetch_array($result);

echo "<table>";

    for ($i = 1; $i < 7; $i++)
    {
        str = "<tr><td>$i</td><td>&nbsp;stripslashes($row[\"price$i\"])</td></tr>";
        eval ("\$str = \"$str\";");
        echo $str;
    }

echo "</table>";
}

Error occurs in the line, where I form $str. Maybe somebody can help me.

escape out of the string before trying to access a php function:

$price_string = "price".$i;
$str = "<tr><td>$i</td><td>&nbsp;".stripslashes($row['$price_string'])."</td></tr>";

and also you need to define it as a variable, hence the added $ at the start, and i think it's safer to define the variable before trying to access it in an array.

Thank You very much, jpmoriarty.

It's working...
