I have a code that enables user to write thier own forum post with title and content, so I modified the code for user to be able to upload thumbnails as well but it's not working, can anyone help with this

Show me the codes you're using.

Hi, here's a Lua script to upload the thumbnail and generate the post in a single form!
Be sure to set the Script as visible only to "Admin & user".

The script first uploads the thumbnail and if the upload is successful the post is created with the thumbnail link added.

Code: Select all

html_form = [=[
<form method="post" enctype="multipart/form-data">
%s <!-- Error message goes here -->
Title:<br>
<input type="text" name="post_title" value="%s" required><br>
Content:<br>
<textarea name="post_content" required>%s</textarea><br>
Thumbnail:<br>
<input type="file" name="post_thumbnail" required><br>
<input type="submit" value="Create post">
</form>
]=]

if (req.method == "POST") then
    error_message = nil

    local upload_param = {
        folderid = 71055, --> Change to the thumbnails folder
        file = req.files.post_thumbnail.full_path
    }
    local upload_ok, upload, info, upload_error = api.file_create(upload_param)
    if (upload_ok) then
        local post_param = {
            forumid = 24031, --> Change to the posts forum
            title = req.post.post_title,
            content = req.post.post_content,
            thumb = upload[0].cdn_link
        }
        local post_ok, post, info, post_error = api.post_create(post_param)
        if (post_ok) then
            url.redirect("/post?id=" .. post[0].id) --> Modify to where you would like to take the user after they generate the post
        else
            error_message = string.format("Post creation error: %s - %s: %s", post, info, post_error)
        end

    else
        error_message = string.format("Thumbnail upload error: %s - %s: %s", upload, info, upload_error)
    end

    if (error_message) then
        html_error = [=[<div class="error-message">%s</div>]=]
        error_message = string.format(html_error, error_message)
    end
end

print(string.format(html_form, error_message or "", req.post.post_title or "", req.post.post_content or ""))

Thank you so much in adavnce I would try all of these,
But for those that asked this is the line of code I used to update the thumbnail, please correct me if I am wrong. What could be wrong

Code: Select all

<div class="menu"><b>Book cover:</b><br/><input type="file" name="thumb" id="thumb"></div>

Then I used %thumbnail% or %thumb% tag to call out the thumbnail at the page where I am displaying the forum list posts

[Hariph]

This is the full code here

Hello! The Post Creator function expects the value of the thumb parameter to be a string, as it is not capable of uploading files.
That's why in the Lua code I provided, the thumbnail is first being uploaded using the File Uploader function and only then will the cdn_link return be used as the value for the thumb parameter of the Post Creator.

Ooh that's why it wasn't working, well I tried the lua cold you provided, it actually worked but its working for only one forum category but I wanted it to work for all forum categories and not just one alone, I want the user to be able to select the category they want to post to, or better still the url can catch the category where the user is coming from and update thier post on that category

What url structure are you using on your forum?
