Drupal 8中如何将页面节点标题传递至Webform

Hey there, let's sort out this issue where you can't tell which specific job an applicant is applying for in your Drupal 8 Webform emails. I’ve tackled this exact scenario before, so here are a few reliable solutions to get it working:

1. Pass the Job Title via URL Query Parameter (Quickest Fix) #

This is the most straightforward approach, perfect if you just need to get the job title into your emails without extra complexity:

• Update the apply button link: Instead of linking directly to your Webform, add a query parameter that pulls the current job node's title using Drupal tokens. For example, set the button URL to:

  /webform/your-form-machine-name?job_title=[node:title]
  

  If your button is part of a Views block or custom template, make sure the token [node:title] is properly resolved to the current job page's title.
• Add a hidden field to your Webform: Create a new hidden field (machine name: job_title works well) in your Webform. Under the field's Default Value settings, select "URL query parameter" and enter job_title as the parameter name. This auto-fills the field with the job title from the URL—users won’t see it, but the data gets submitted with their form.
• Include the field in your email template: Edit your Webform’s email settings, and in the message body, add something like:

  *Applied Job Position:* [webform_submission:values:job_title]
  

  Now every submission email will show the exact job the user applied for.

2. Use Webform Context Entities (More Elegant for Node-Linked Forms) #

If your jobs are Drupal content nodes, you can link the Webform directly to the job node to pull data without extra fields:

• Enable Webform context: Edit your Webform, go to Settings > Form Settings, scroll to the "Context" section, check "Enable context", then add a Node context. Configure it to "Load from URL parameter" (set the parameter to node so it uses the job node's ID).
• Update the apply button link: Adjust the button URL to pass the job node's ID:

  /webform/your-form-machine-name?node=[node:nid]
  

• Call the node title directly in your email: No need for a hidden field—just add this to your email message body:

  *Applied Job Position:* [webform_submission:context:node:title]
  

  This pulls the title straight from the linked job node, keeping your form clean.

3. Custom Module Hook (For Complex Logic) #

If you need more control (like handling edge cases or additional data), use a custom Drupal hook to inject the job title into the submission:

• Create a small custom module, then add this code to your .module file:

  function your_custom_module_webform_submission_presave(\Drupal\webform\WebformSubmissionInterface $webform_submission) {
    // Grab the job title from the URL query parameter
    $request = \Drupal::request();
    $job_title = $request->query->get('job_title');
    
    // If we have a valid title, save it to the submission (use your field's machine name)
    if (!empty($job_title)) {
      $webform_submission->setElementData('job_title', $job_title);
    }
  }
  

• Make sure you have a job_title hidden field in your Webform, then reference it in your email template just like in method 1.

Pro Tip #

Always test each solution by clicking apply buttons on different job pages, submitting the form, and verifying the email includes the correct job title. It’s easy to miss a token or parameter name, so a quick test saves headaches later!
