Archive page `dataLayer` structure
Easy access to your archive data with a standard event name and subject.
The search key in this object allows you to get the search term and total results to detect invalid searches. Very useful for Matomo Tag Manager, and nice hack for Google Tag Manager.
As each event handles wpcf7_form_details , here is an example of the object values when the form is submitted with invalid fields.
"wpcf7_form_detail": { "contactFormId": 145, "pluginVersion": "6.0.3", "contactFormLocale": "en_US", "unitTag": "wpcf7-xxxxxx", "containerPostId": 0, "status": "validation_failed", "inputs": [ { "name": "your-message", "value": "" }, { "name": "your-name", "value": "" }, // All other inputs ], "formData": {}, "apiResponse": { "contact_form_id": 145, "status": "validation_failed", "message": "One or more fields contain an error. Please check and try again.", "invalid_fields": [ { "field": "your-name", "message": "Please complete this field..", "idref": "last_name", "error_id": "wpcf7-f145-o1-ve-your-name" }, { "field": "your-first-name", "message": "Please complete this field.", "idref": "first_name", "error_id": "wpcf7-f145-o1-ve-your-first-name" }, // All other invalid fields ], "posted_data_hash": "", "into": "#wpcf7-f145-o1" } }

Gettingstarted.
To start using the dataLayer plugin, you need to install it from the marketplace or manually. Then activate the plugin in the WordPress administration. You don’t need to configure anything special for standard use. Once the plugin is activated, you will need to understand the different structures of the generated dataLayer object.
In your favorite Tag Manager:
01To trigger a tag at a specific moment, you will need to create a trigger based on the value of the event key of the desired page.
02To read values from the dataLayer object and report them to your audience analysis tools, you will need to create custom variables of the “data layer” type and enter the full path.
Example of configuring a variable: for a following datalayer object:
{ "event": "view_single_post", "page": { "type": "post", "id": 1, "url": "https://example.com/blog/super-article-path", "path": "/blog/super-article-path", "title": "Super article title | Example", "post_type": { "name": "post", "label": "Posts", "label_singular": "Post", "label_plural": "Posts", "description": "The super post type description" } } }
To collect the post type label, you will need to enter the value page.post_type.label in your custom variable. This variable should be triggered with a custom trigger based on the custom event view_single_post .
Job done !
