PHP Integrating PHP with Databases Filtering Input for Queries Creating the Search Function

$total_items = get_catalog_count($section, $search);

My search won't work unless if I remove the second parameter, the $search variable. Then it works perfectly, but doesn't match up to teachers code and won't work with both $section and $search.

Any idea where I am going wrong?

You would have to at least post your code for get_catalog_count in order for someone to help.

KRIS NIKOLAISEN : I've posted my code below. There is a lot of code. I tried to post the most important stuff only.

Took me a while but I found the answer to my own question. In the if() statement, on the third line right below $sql, I didn't have an space before WHERE.

My code was "WHERE title LIKE ?" and it should have been " WHERE title LIKE ?".

I can't believe such a minor detail was driving me crazy. Was almost impossible to notice because there are no typos or spelling mistakes, just simply missed the empty space.

SQL was reading my code as "SELECT COUNT(media_id) FROM mediaWHERE title LIKE ?"

It's easier to pick up on this when the code is on one line, but our conditionals forced us to have it on a separate line.

CORRECT

if (!empty($search)) {
            $results = $handle->prepare(
            $sql
                . " WHERE title LIKE ?"
            );
            $results->bindValue(1, '%'.$search.'%', PDO::PARAM_STR);
        }

PS. I am still confused why we need to pass $search to get_catalog_count. It works both with and without????

$total_items = get_catalog_count($section, $search);
