weird warning message for mysql query

Recommended Posts

here's my query:

 

//select the category the url belongs to

$sql = "SELECT * from ". table_stores ." where domain=". $domain;

 

$category_id = $db->get_results($sql);

 

However, when I type in a domain name on web page, this query gives me this warning message:

 

Warning: Unknown table 'circuitcity' in where clause in /public_html/libs/db.php on line 233

 

the code block in db.php is:

 

if ( $str = @mysql_error($this->dbh) )

{

$is_insert = true;

$this->register_error($str);

$this->show_errors ? trigger_error($str,E_USER_WARNING) : null; //This line is 233

return false;

}

 

circuitcity is actually not even a table in mysql database. Domain is a column in the table of stores.

 

Can someone help me figure out where is wrong?

 

thanks!

yes, table_stores is a constant. Now it works, but I have problem fetching values

<?php

$category_id = $db->get_results($sql);

//check if category id exists for the particular domain

$categoryid = $category_id['category_id']; // category_id is a column in the database table _stores

if (!$categoryid){

  $categoryid = 0;

  }

echo $categoryid;

 

?>

 

This code gives me $categoryid = 0 even though there are records in the table.

 

Am I missing something?

 

thanks again!

Very unsatisfactory post. You need to be very clear with your questions if you expect members on this forum to respond to you.

 

Issues with your post:

 

1) You don't show what the current query ($sql value) is.

2) We don't see where or how you're actually running the query (unless get_results() does it, but how are we supposed to know that?).

3) We don't know what get_results() does exactly. We don't know if you're using a database abstraction layer, a home grown function or what.

4) We don't know if get_results() really returns an array, resource object, or an object, or something else.

 

It's up to you to help yourself by putting debug echo's in strategic places in your code to see where things are going wrong.
