Question

I have a controller action that uses a sql query:

    $tag = $this->params['tag'];

    $this->set('projects', $this->Project->query('SELECT * FROM projects INNER JOIN projects_tags ON projects.id = projects_tags.project_id INNER JOIN tags on projects_tags.tag_id = tags.id WHERE tags.tag LIKE $tag'));

As you can see at the end I want to use a where clause with the $tag variable but I’m not sure how the syntax would go. As I’m getting the error

Unknown column '$tag' in 'where clause'

Can someone steer me in the right direction?

Modify your query as:

$this->set('projects',
$this->Project->query("SELECT * FROM projects
                       INNER JOIN projects_tags
                       ON projects.id = projects_tags.project_id
                       INNER JOIN tags ON projects_tags.tag_id = tags.id
                       WHERE tags.tag LIKE '" . $tag . "'") //problem was here
                     );

and it will work.
