How to I get values of a page by a field tag?

[rjgamer]

Hi,

how do I get the values of a page tagged by specific field tag?

Something like $page->getByTag('custom'), if I had tagged multiple fields by a tag called "custom".

Thanks,

You would ask with $pages->get(„yourfieldname=requiredvalue“),

or with $pages->find()

If you not allready have setup your tags field, you may look at the pagereference fieldtype, or the options fieldtype. 

Your selector to find pages with the requested flag may include specified templates, parent or others, to be more precise. 

And if you not allready know the differences between get and find, look it up in the docs, as this is fundamental knowledge in PW.

Try:

// Get names of fields on the page that are tagged with "custom"
$custom_field_names = $page->fields->find('tags=custom')->explode('name');

// Do something with the values of those fields
foreach($custom_field_names as $custom_field_name) {
    echo $page->$custom_field_name;
}

Thanks!

I already found $page->fields in the docs, but didn't reconise that I could use ->find('tags=custom').

Sorry, I think you misunderstood my question.

I asked for a solution to find field values of a page, based on a specific field tag and not pages.

Thank you Robin S,

I find myself continually (eventually) finding the answers I am looking for with your name attached. Many thanks!

Had gone round and round using the wrong method for the job I wanted.
In my case, was just trying to clean up fields added by a module generated page I was playing with.

Deleting api generated page, templates and fieldgroups was very easy but kept on bumping up against deleting the fields.
Finally realised I could just set a tag on them, but kept using the (very wrong) getTags() method instead of the delightfully easy find('tags=...).

Knew I was doing something wrong and when I eventually found your advice was acting as expected in minutes. 
 

public function ___uninstall() {
	
		parent::___uninstall();	
		$page = $this->pages->get('name='.self::PAGE_NAME);
		
		if ($page->id) {
		    $page->delete();			
		}
		
		$addedTemplate = $this->templates->get(MODULE_NAME);
		if ($addedTemplate) {
		    $this->templates->delete($addedTemplate);
		}	
		
		$addedFieldgroup = $this->fieldgroups->get(MODULE_NAME.'-fieldgroup');
		if ($addedFieldgroup) {		
		    $this->fieldgroups->delete($addedFieldgroup);
        		
        }
		
		$addedFields = $this->wire->fields->find('tags='.MODULE_NAME.'');

		foreach($addedFields as $addedField) {
		
		    $field = $this->wire->fields->get($addedField);
            $this->wire->fields->delete($field);
		
		}

In this part, each $addedField is already a Field object so you could simplify it to:

$addedFields = $this->wire->fields->find('tags='.MODULE_NAME.'');
foreach($addedFields as $addedField) {
	$this->wire->fields->delete($addedField);
}
