Add image to post using a hook? « Gravity Support Forums

Hi,

I understand that it's not possible to add (a thumbnail of) an image to a post directly. Can it be done using a hook? The currently proposed solution by tweaking the theme feels a little hackish ;-)

Thanks!

Bart

You can always use the built in gallery functionality to display the post image. You can use something like the Cleaner Gallery plugin to add more advanced options to the gallery ouput if you need.

There was a similar solution in the following thread that you might find helpful.

Hi Kevin,

thanks for your reply! I saw that solution and yes it would work, but I don't really like that solution. For one, you wouldn't see the images when editing the posts and things would get rather awkward that way.

If only I could fetch the new post's ID after the data has been saved, then I could probably write some code to retrieve the thumbnail ID from the gallery and add the proper HTML to the posts's body.

Any ideas on that?

Thanks!

Bart

Bart,
Yes, you can add the image to the post content using the post_submission hook.
Try the following:

add_filter("gform_post_submission", "set_post_content", 10, 2);
function set_post_content($entry, $form){

     //Replace 1 with your actual form id
    if($form["id"] != 1)
       return

    //getting post
    $post = get_post($entry["post_id"]);

    //changing post content.
    //NOTE: Replace 8 (in $entry[8]) with your actual image field id. You can find the id by inspecting the page markup
    $post->post_content = "This is my image <br/> <img src='" . $entry[8] . "'>";

    //updating post
    wp_update_post($post);
}

I'm looking to add the Post ID to the Post Title after somebody submits a new entry (via Post Fields). It's for a job board I'm creating, so the post title would be '###: Job Title' and the slug would be URL.com/###-job-title/.

Using Alex's code above, it seems as though you could modify line #16 to add the Post ID to the newly created post. Anyone have any idea how that would be written?

Would it be something like this?

$post->post_title = $entry["post_id"] .": ". $entry[8] ;

Do you have to use the Post ID? Could you use the Entry ID associated with the form submission? Doing so would allow you to to implement this without requiring custom code. You could use the Post Title Template functionality to append the entry_id to the end of the post title content.

I did try that, Carl. If fact, out of 'embeded post id', 'post id', and 'entry id', entry was the only one that worked (by inserting the number).

I could use entry id, but I really want to have the post id, since it is what is used when using short URLs (via WP Stat's Get ShortURL button). I also wanted to use the post id because it would be easier for the people maintaining the website to search by the post ID when editing content for that specific post.

Hi Eric, here is a quick snippet that will add the post id to the post title when the form is submitted. It works pretty much exactly like you thought it would. :)

http://pastie.org/1218925

add_action("gform_post_submission_14", "update_gform_post_title");

Replace the "14" with the ID of your form.

$post->post_title = $post_id . ': ' . $entry[1];

Replace the "1" in "$entry[1]" with the id of your post title field.

Hope that helps. :)

PS - This would go in your functions.php file.

I just tried the script from Alex Cancado useing the using the post_submission hook, it is powerfull.
I made a page put in a form with post a article function, then I put up the script from Alex, made a new post useing the form and then all the content on that page was away.... only the text ”This is my image” was there.
I am sure I made a mistake somehow but how... I did not want to post into the page, but make a new post of course. Without the script my form works fine and make a post in the right category.
I just want to find a way to put a file or a link to that uploaded file or?

@lindebjerg Please explain what you are trying to do, i'm not quite clear what you are trying to customize or what you are trying to accomplish.

Thanks Carl, I am almost there thanks to your answer on another post of mine.
I have a intern or private site, where the users must be able to make a post with a thumb, works perfect setting it in the up right corner of the post and used as thumbnail or image picture in my theme (Genesis/Child from StudioPress).

My last problem, I would like be able to upload more than one file and make a link out of the uploads to put into the body.

You should be able to add links, etc. to your conte template just like you would add images. However, as I mentioned in your other post, conditional statements are not possible with the content template. So it's best to only output fields that are required in the content template.
