Post creation - Validate if title already exist before creating

    Hi everyone,

    I have a couple of Gravity Forms to populate some custom types (user generated content).

    For one of those custom type, users shouldn't be able to create a new "post" if one with the same title already exist. Instead, I would like to redirect them to the existing post.

    I'm a bit new with Wordpress so I'm not sure how I should do this.

    PS : I only need some hints, but if somebody is willing to help me with this and can spare an hour or two, I would be willing to pay.

    Edit : It's may be easier if I explain why I want to do this : Users (mostly adolescents) will type a job they would like to do. If it's not in the database, it will create a new post where they can discuss about it (comments) and/or do a "Facebook Like". If the job is already in the database (also going to use autocomplete), they will be redirected to the exising post to continue the discussion.

    So hints first.

    • You'll need to use the gform_pre_submission hook to compare the submitted post title to all of the post titles currently active on your site.
    • If the same post title does exist, redirecting the user directly to that post without explanation might be a little confusing. It might be more ideal to handle this similar to how Gravity Forms currently handles errors; it returns users to the form with the incorrect fields highlighted. In your case, I would recommend just adding a notification at the top of the form that let's the user know a job with that post title already exists and provide a link for them to go view it.

    This might be a difficult undertaking if you're new to WordPress/Gravity Forms. I do provide freelance support for WordPress and Gravity Forms so if you're interested, please feel free to get in touch: david@ounceoftalent.com.

    Hope this helps! :)
