How do I create an add-on that allows a user to click a link and call php code?

[AndyB]

I would like to create an add-on that allows an admin to change the date of a post. Under each post there will be a link the admin can click. A form will be displayed and when submitted the database is updated. I already have a stand alone php script to do this, but I would like to learn how to create a proper add-on.

Jake told me the initial steps.

1) You need to create a route so you have a location to request with the link.
2) You need a controller for that route to actually execute php code when that link is clicked.
3) Then add the link to the template.

So lets start with step #1, how do I create a route?

I think you need extends ControllerPublic_Post so you can do that.

You define that route in the ACP. And you won't be extending any controller if you are defining a route.

Wouldn't it be easier to use an add-on released by @Waindigo:

Hi Jeremy,

I would like to learn how to create an add-on. I looked at the add-on "Edit Post Date by Waindigo", but it's very complicated and I have no idea what does what. So I hope to be able to create this add-on with help from others.

So how do I define a route? Also will the XML file for the add-on define the route as well?

 

[AndyB]

I assume to create a route this screen in the Admin CP is used.



Route Prefix: tools
Route Type: Public
Route Class: I have no idea what goes here
Use class to build link: Only when data is provided
Add-on: Change Date

As I said before. Create new route isn't nessasery, Why You don't extends XenForo_ControllerPublic_Post then you can using actionChangeDate. If you create new route you need create new ControllerPublic... Not good for your aim

So I hope to be able to create this add-on with help from others.

Hi Nobita.Kun,

Thank you for your assistance. I have no idea what "extends XenForo_ControllerPublic_Post" means.

What I would like to do is have a link located below the post. When the user clicks the link it will show them a few input fields and a submit button.

• Display link you should using Template_Hook for display
• Display form overlay in class link you must use: class="OverlayTrigger"
• Want to change datetime of post you need post_id so extends XenForo_ControllerPublic_Post is better for that. You can find post_id by $postId = $this->_input->filterSingle('post_id', XenForo_Input::UINT); then to do something
• When You extends that so link should be for using: {xen:link 'posts/whatever', $post}

I'll start with the last bullet. Lets say I change whatever to "changedate". So when the user hovers over the link would it display something like:

http://www.mysite.com/forums/posts/123456/changedate

? Are your forum using XenForo Software? Look like Its other software

 

[AndyB]

• Display link you should using Template_Hook for display

Could I use Template Modification instead?

 

[AndyB]

? Are your forum using XenForo Software? Look like Its other software

Yes I'm using XenForo software 1.2.0.

 

[truonglv]

Could I use Template Modification instead?

No. I said Template_Hook. You can use hook_name: post_public_controls

Yes I'm using XenForo software 1.2.0.

Ha? Are you create new Event Listener: load_class_controller

 

[AndyB]

At this point all I have created is the Add-on.

No. You need create new Event Listener here: {boardUrl}/admin.php?code-event-listeners/

 

[AndyB]

No. You need create new Event Listener here: {boardUrl}/admin.php?code-event-listeners/

Okay I'll do that in a second.

But first if I assume correctly, I need to create an index.php file here:

library/Andy/ChangeDate/index.php

<?php

class Andy_ChangeDate_index
{
   public static function templateHook($hookName, &$contents, array $hookParams, XenForo_Template_Abstract $template)
   {   
     if ($hookName == 'post_private_controls')
     {
       $contents = $contents . 'test';
     }
   }
}

 

[AndyB]

Code Event Listener.

 

[Jeremy]

No. Wrong class and your PHP is invalid.

 

[Chris D]

No. I said Template_Hook. You can use hook_name: post_public_controls

Ha? Are you create new Event Listener: load_class_controller

Why are you insisting he uses a template hook when they are deprecated?

 

[AndyB]

Hi Chris,

Would it be better to use Template Modifications?
