[SOLVED] extract error


Clinton

Recommended Posts

I'm getting an extract error that generally shows up when there are no rows to be fetched. However, I use this same exact query (cut and paste) elsewhere but it just produces an error here. What am I doing wrong?

 

<?php
$query1 = mysql_query("SELECT * FROM head WHERE did = '$id' AND rname = '$rname'");
$row1 = mysql_fetch_assoc($query1);
extract($row1);
?>

<center>
<b><?php echo $fname; ?> <?php echo $mname; ?> <?php echo $lname; ?></b><br />
</center>

///The Above Code Works Fine///

<?php
$query1 = mysql_query("SELECT * FROM structure WHERE did = '$id' AND rname = '$rname'");
$row1 = mysql_fetch_assoc($query1); 
extract($row1); /// I'm Getting My Error Here ///
?>

 

 

EDIT

 

Error just FYI:

Warning: extract() [function.extract]: First argument should be an array

Not checking your query returns results.

 

<?php
  if ($query1 = mysql_query("SELECT * FROM head WHERE did = '$id' AND rname = '$rname'")) {
    if (mysql_num_rows($result1)) {
      $row1 = mysql_fetch_assoc($result1);
      extract($row1);
?>
<center>
<b><?php echo $fname; ?> <?php echo $mname; ?> <?php echo $lname; ?></b><br />
</center>
<?php
    }
  }
?>

 

Edit: Your also passing $query1 instead of $result1 to mysql_fetch_assoc.

Ok, yes, I may be doing that wrong but that's not the answer (I will fix that though). :-)

 

If I remove the first query then the second query works just fine. They don't like each other for some reason and I'm not sure why. Even if they're renamed so they're not identical.

As to the interaction, your unconditional use of extract() is probably overwriting variables that the second query is using. extract() should only be used with one of the PREFIX options so that the variables it creates are unique to that query and don't have a chance of overwriting any existing program variables.
