abdus Posted August 17, 2017 Share Posted August 17, 2017 I'm trying to add a new option to InputfieldTextarea. Depending on that option, I want to change how the input is rendered. I also want to change this option depending on different templates and repeaters, meaning it can have different values for different fieldgroups. I hooked into three methods: $this->addHookBefore('InputfieldTextarea::render', $this, 'hookInputRender'); $this->addHookAfter('InputfieldTextarea::getConfigInputfields', $this, 'hookInputSettings'); $this->addHookAfter('InputfieldTextarea::getConfigAllowContext', $this, 'hookInputContext'); In hookInputSettings, I build the additional option protected function hookInputSettings(HookEvent $e) { /** @var InputfieldTextarea $field */ $wrapper = $e->return; $field = $e->object; /** @var InputfieldSelect $font */ $font = $this->modules->get('InputfieldSelect'); $font->label = $this->_('Font'); $font->name = 'fontFamily'; $font->addOptions(self::fontOptions); $font->attr('value', $field->fontFamily); $wrapper->add($font); $e->return = $wrapper; } It shows up in field settings with no problem When I pick an option and save, it even shows up in the database. However, I cannot get the properties of that field in that fieldgroup context. Most other inputfields can get their inputfield settings because are inside a class that extends Inputfield, so $this->myOption works. If I hook into FieldtypeTextarea::getConfigInputfields, it works too, because getConfigInputfields method is called with $this as its argument, inside hooks it's possible to access fieldgroup specific settings. But for Inputfield, it's not given any arguments, so hooking Inputfield::getConfigInputfields, you won't be able to get any information about the context. // /wire/core/Field.php public function ___getConfigInputfields() { // ... if(!$fieldgroupContext || count($allowContext)) { // ... try { $fieldtypeInputfields = $this->type->getConfigInputfields($this); // ... } // ... } $inputfields = $this->wire(new InputfieldWrapper()); // ... if($inputfield) { if($fieldgroupContext) { $allowContext = array('visibility', 'collapsed', 'columnWidth', 'required', 'requiredIf', 'showIf'); $allowContext = array_merge($allowContext, $inputfield->getConfigAllowContext($this)); } // ... $inputfieldInputfields = $inputfield->getConfigInputfields(); // ... } // ... } So, as a solution I gave it $this as a parameter // $inputfieldInputfields = $inputfield->getConfigInputfields(); $inputfieldInputfields = $inputfield->getConfigInputfields($this); Now everything works without any hacks. It works in field settings, templates, repeaters just fine. protected function hookInputSettings(HookEvent $e) { // ... $field = $e->arguments(0); // ... $font->attr('value', $field->fontFamily); // WORKS! // ... } I wanted to write this post because it drove me mad last night. I guess the next step is to make a pull request. Link to comment Share on other sites More sharing options...
