[Submit Button] field when clicked runs a custom code

Recommended Posts

Hello everyone,

I'm looking for a way to add a submit button ('Generate PDF') for a set of templates, which generates a PDF when clicked. So, a submit-button field to which I can attach attach a piece of code. I don't want to run it every time I save, because that will be too much time-consuming.

I found https://processwire.com/talk/topic/8457-add-a-new-action-button-to-page-edit-screen/?hl=%2Badmin+%2Bbutton , but I can't seem to get it working. It should be placed inside the admin.php file right?

Or is making a module the best way to do this...

Best,

Charlie

*** EDIT ***

I'm currently in the middle of making the [GENERATE PDF]  button module. I found the Page::editable hook which works great. Somehow it also parses immediately the parent, and because I only want to parse the current page, I remove the parent like this:

$page = $event->object;
$page->parent = ""; // remove parent!

Is this good/okay/bad practice?

Then I'm trying to add a button to the template like the following:

$field = $this->modules->get('InputfieldButton');
$field->attr('name', 'generate_pdf');
$field->attr('class', $field->class);
$field->attr('value', '[GENERATE PDF]');
return $event->return->append($field);

But this throws me an error on the appending (Error: Call to a member function append() on boolean (line 60)...

The follow up question would be: how can I add an event to when this button has been clicked, and use the current available information of that page :-)

      Hey all, hope you're feeling well these days!
      Short question: Under "Setup > Templates" it's possible to sort the templates by last modified. Is this possible for fields view to?
      Long explanation:
      Currently I am in the process of programming a reusable template and often have to copy several fields & templates from different PW installations into my "master version".
      Therefore it would be good to see already in the field list when the last modification has taken place.
      Stay healthy & don't forget to wash you hands - many greets!

      Here's a small new module that adds a "Manage tags" button to the template list, just like the field list already has.
      Easily add, remove and change tags for your templates.

      This module is inspired by and similar to the Template Stubs module. The author of that module has not been active in the PW community for several years now and parts of the code for that module didn't make sense to me, so I decided to create my own module. Auto Template Stubs has only been tested with PhpStorm because that is the IDE that I use.
      Auto Template Stubs
      Automatically creates stub files for templates when fields or fieldgroups are saved.
      Stub files are useful if you are using an IDE (e.g. PhpStorm) that provides code assistance - the stub files let the IDE know what fields exist in each template and what data type each field returns. Depending on your IDE's features you get benefits such as code completion for field names as you type, type inference, inspection, documentation, etc.
      Installation
      Install the Auto Template Stubs module.
      Configuration
      You can change the class name prefix setting in the module config if you like. It's good to use a class name prefix because it reduces the chance that the class name will clash with an existing class name.
      The directory path used to store the stub files is configurable.
      There is a checkbox to manually trigger the regeneration of all stub files if needed.
      Usage
      Add a line near the top of each of your template files to tell your IDE what stub class name to associate with the $page variable within the template file. For example, with the default class name prefix you would add the following line at the top of the home.php template file:
      /** @var tpl_home $page */ Now enjoy code completion, etc, in your IDE.

      Adding data types for non-core Fieldtype modules
      The module includes the data types returned by all the core Fieldtype modules. If you want to add data types returned by one or more non-core Fieldtype modules then you can hook the AutoTemplateStubs::getReturnTypes() method. For example, in /site/ready.php:
      // Add data types for some non-core Fieldtype modules $wire->addHookAfter('AutoTemplateStubs::getReturnTypes', function(HookEvent $event) { $extra_types = [ 'FieldtypeDecimal' => 'string', 'FieldtypeLeafletMapMarker' => 'LeafletMapMarker', 'FieldtypeRepeaterMatrix' => 'RepeaterMatrixPageArray', 'FieldtypeTable' => 'TableRows', ]; $event->return = $event->return + $extra_types; }); Credits
      Inspired by and much credit to the Template Stubs module by mindplay.dk.

      Hi, 
      I'm using this kind of setup (https://processwire.com/blog/posts/language-access-control-and-more-special-permissions/#language-page-edit-permissions) in order to control the page edit permissions. Now I'm wondering if it's possible to hide the "none-ediable" language-tabs instead of striking them through.

      Many greets...

      Another little admin helper module...
      Template Field Widths
      Adds a "Field widths" field to Edit Template that allows you to quickly set the widths of inputfields in the template.

      Why?
      When setting up a new template or trying out different field layouts I find it a bit slow and tedious to have to open each field individually in a modal just to set the width. This module speeds up the process.
      Installation
      Install the Template Field Widths module.
      Config options
      You can set the default presentation of the "Field widths" field to collapsed or open. Field widths entered into the Template Field Widths inputfield are only applied if the Edit Template form is submitted with the Template Field Widths inputfield in an opened state. "Collapsed" is the recommended setting if you think you might also use core inputs for setting field widths in a template context. You can choose Name or Label as the primary identifier shown for the field. The unchosen alternative will become the title attribute shown on hover. You can choose to show the original field width next to the template context field width.
