Question

I am working with MySQL in conjunction with ExpressionEngine 2.2.1. This version of ExpressionEngine automatically comes with a Query Module, which I am using to filter and display entry results from a module called Freeform. I am using Freeform version 3.1.1. All of these elements are working well together and displaying the desired results on my local setup. However when I push my code to production, I am receiving this error:

Fatal error: Call to a member function num_rows() on a non-object in /var/www/vhosts/xxxxxxxxx.com/systemxxx/expressionengine/modules/query/mod.query.php on line 183

Here is this section of the code beginning on line 183 of mod.query.php (I did not code this php, nor have I ever coded php, this was already included with the site that I am working on.):

183          if ($query->num_rows() == 0)
184          {
185          return $this->return_data = $this->EE->TMPL->no_results();
186          }

Here is how I am using the Query Module in my HTML Template:

{exp:query sql="SELECT first_name, last_name, email, city FROM exp_freeform_entries WHERE city = 'New York'"}
    <tr>
        <td>{first_name}</td>
        <td>{last_name}</td>
        <td>{email}</td>
        <td>{city}</td>
    </tr>
{/exp:query}

Does anyone know why this error is occurring? Why would it be occurring on production but not locally?

Any help would be greatly appreciated!

Answer 1

Check to make sure the database in Production has the same structure as your Local environment.

Perform the following steps from phpMyAdmin or your favorite MySQL GUI client:

1. Select your ExpressionEngine database
2. Execute the following SQL Statements:
3. DESCRIBE exp_freeform_fields;
4. SELECT name FROM exp_freeform_fields;

Compare the results from your Local MySQL Database to your Production MySQL Database.
