  I have written a plugin which can store a table of technical specifications for each post (product) in an own database table. For the search function of the site I want to add a custom parameter to the array passed to WP_Query(). I have no clue where to register this custom parameter so that it is handled by the plugin as soon as WP_Query() executes the search.Is there a hook that I can use in the plugin to restrict the posts found by WP_Query() to a certain set matching the specs given? Or do I

  images attachments fatal-error
  When users upload very large photos and memory is tight, it seems like WordPress runs out of memory – fails to resize the uploaded photos and does not create the necessary metadata (_wp_attachment_metadata entry in wp_postmeta is not created).The worst part is that the user is never notified. At most I get an “HTTP error” message.Is is possible to somehow add an error message that will warn the user and remove the inconsistent file/database entries? How come this is not standard WP behavior?
