Hello,
I want to access an external database within a snippet (without having to worry about xPDO...) - just a straight and simple way.
I tried it using PHP directly, something like:
$link = mysql_connect("myhost", "myuser", "mypwd");
mysql_select_db("mydb");
$query = "Select whatever";
$result = mysql_query($query);
After that I can return the field names of the query like that:
$y=mysql_num_fields($result);
for ($x=0; $x<$y; $x++)
{
echo "<th>".mysql_field_name($result, $x).'</th>';
}
But then I need to extract the contents, and this is what does not work within modX (same script works without modX directly using PHP).
while ($line = mysql_fetch_object($result))
{
echo "<tr>";
foreach ($line as $col_value)
{
echo "<td>$col_value</td>";
}
echo "</tr>";
}
mysql_free_result($result);
mysql_close($link);
I know that the output should be in a return value, error handling is missing, silly variable names ...
But this would be the next step. I also tried mysql_fetch_row instead. It looks like it's iterating but as soon as I want to access any value of the row the snippet breaks and I get an empty page.
Any idea? Did someone do something similar?
Thomas
