Add a new action button to page edit screen

[Ivan Gretsky]

Good day!

Sorry for not finding it if it is already out there in the forums. I did try, but probably do not even know the right words to put into a searchbar.

I need to put a button in the page edit screen of the admin for a specific template. When a user clicks on that, he should be led to creation of a new page, related to the one he is on.

Making it more of a real-life situation: it is a company page with a template "company" under "company-root".  I need to place a "Create new classified Item" button on the edit screen for every saved page with that template  When a user clicks on that he should be led to creation screen for a new page with "classified-item" template to be stored under "classified-root" template.

I guess this should be a module which hooks into some method... But I am in the beginning of my journey to PW module-making, so please give me some (preferably clear and simple) directions.

@Ivan,

Part of my stock toolkit when building sites is a "save action".

It is a simple way to run some action when the user saves; they select the save action, and click save, and the action runs. It usually hooks into SaveReady.

It could be anything from calculating/validating/correcting/filling in blank fields to things like deleting children, renaming assets (images, files) etc..

I usually use a special select field for this, but you could use a checkbox. If I needed to create the functionality you are describing right at this moment, i would make the save action a checkbox and then have next to it After save: Create new classified Item;

your module code would then simply create a new page under the specified parent and redirect the user to that edit page...

Yes, I understand what you are suggesting. Thank you!

But this solution seems to me a bit "clumsy". I think it would be more convinient for the client to have a tab like "Children" with a list or related classified items and a big green button "Add new classified item". When user pushes that button he should be send to a new page creation screen with "classified-item" template chosen under specified root page AND company page field set to the company page he came from.

Do you have an idea how this could be done?

maybe a part could be done by restricting children - parent relation via family settings? Template for parent that only allow a single Template for children. That way, when adding a child, it has the right Template and the right position. Only thing left is the population of your field.

Yes, but I do not know how to insert a tab with classified items and a button in the first place ))  Could you help on this too?

[LostKobrakai]

How about FieldsetTab and a PageTable?

Oh, no haven't done those things.

Maybe there are already modules out that do similar things where one can study the code?

[adrian]

Some examples from some of my modules - only because I quickly know where I have used these things 

I'll link to the hook, so obviously also view the called function as well.

New tab

https://github.com/adrianbj/ProcessRedirectIds/blob/master/ProcessRedirectIds.module#L104

$this->addHookAfter('ProcessPageEdit::buildForm', $this, 'addTab');

Add content to existing tab

https://github.com/adrianbj/BatchChildEditor/blob/master/BatchChildEditor.module#L100

$this->addHookAfter('ProcessPageEdit::buildFormChildren', $this, 'addChildTabContent');

Obviously with this, "buildFormChildren" could be replaced with buildFormSettings etc.

Hope that helps.

yes - this is a texbook page table scenario...
