Introduction

Fetch dynamic forms with real-time submissions and data collection.

🎯 What does this module do?

The Forms module lets you retrieve forms - contact forms, surveys, registrations, feedback forms - and collect user submissions with validation, file uploads, and automated notifications.

Think of it as your form builder - you create forms in OneEntry admin panel, display them in your app, and collect responses automatically.

📖 Simple Explanation

Imagine you need to collect information from users:

• 📞 Contact Form - name, email, message, phone
• 📋 Survey - multiple choice questions, ratings
• 👤 Registration Form - user details, preferences
• 💼 Job Application - resume upload, cover letter
• 📝 Feedback Form - ratings, comments, suggestions
• 🎟️ Event Registration - attendee info, ticket selection

Instead of building forms from scratch:

• ✅ Create forms in OneEntry admin panel (drag & drop fields)
• ✅ Fetch form structure dynamically
• ✅ Submit data to OneEntry (automatic storage)
• ✅ Validate fields (required, email format, file types)
• ✅ Get notifications when forms are submitted
• ✅ View responses in admin dashboard

Real-world example:

Without Forms Module (manual):
- Build form HTML/validation manually ❌
- Set up backend to store submissions ❌
- Create database tables ❌
- Build admin panel to view responses ❌
- Write email notification code ❌

With Forms Module (automated):
- Create form in admin panel ✅
- Fetch form structure via API ✅
- Submit data → Auto-stored ✅
- View responses in dashboard ✅
- Auto email notifications ✅

✨ Key Concepts

What is a Form?

A form is a structured way to collect information from users:

• Fields - Input elements (text, email, checkboxes, file upload)
• Validation - Rules (required, format, min/max length)
• Submissions - User responses stored in database
• Structure - Form layout defined in OneEntry
• Dynamic - Fetch form structure from API, render in your app

Form Lifecycle

1. Create form in OneEntry admin

2. Define fields (name, email, message, etc.)
   ↓
3. Set validation rules
   ↓
4. Fetch form structure via SDK
   ↓
5. Render form in your app
   ↓
6. User fills form
   ↓
7. Submit data to OneEntry
   ↓
8. Validation happens
   ↓
9. Data stored in database
   ↓
10. Notifications sent (email, webhook)

Form Field Types

Common field types you can use:

Field Type	Description	Example Use

📋 What You Need to Know

Form Structure

Every form has these key fields:

{
  id: 123,
  marker: "contact_form",   // Unique identifier
  localizeInfos: {
    title: "Contact Us",    // Form title
    description: "Get in touch" // Form description
  },
  fields: [   // Form fields
    {
      marker: "name",
      type: "text",
      localizeInfos: { title: "Name" },
      isRequired: true,
      validation: { minLength: 2, maxLength: 50 }
    },
  ],
  statusId: 1,                 // 1 = active, 0 = draft
  isActive: true,              // Is form enabled
  successMessage: "Thank you!" // Message after submission
}

Field Validation

Each field can have validation rules:

{
  "marker": "email",
  "type": "email",
  "isRequired": true, // Must be filled
  "validation": {
    "format": "email",  // Must be valid email
    "minLength": 5,     // Min 5 characters
    "maxLength": 100,   // Max 100 characters
    "pattern": "^[a-z0-9]+@[a-z]+\\.[a-z]{2,}$"  // Custom regex
  }
}

Common validation rules:

• isRequired - Field must be filled
• minLength - Minimum text length
• maxLength - Maximum text length
• format - Email, phone, URL format
• pattern - Custom regex pattern
• min / max - Number range
• fileTypes - Allowed file extensions
• maxFileSize - Maximum file size

📊 Quick Reference Table - Methods

Method	What It Does	When to Use
getAllForms()	Get all forms (paginated)	List all available forms
getFormByMarker()	Get form by marker	Fetch specific form in code

Note: To create/edit forms, use OneEntry admin panel. The SDK is for fetching forms and submitting data.

❓ Common Questions (FAQ)

How do I create or edit forms?

Forms are created in OneEntry admin panel:

1. Log in to OneEntry admin
2. Go to Forms section
3. Create new form or edit existing
4. Add fields (drag & drop)
5. Configure validation rules
6. Activate the form

The SDK is for fetching forms and submitting data, not creating forms.

---

How do I validate form data before submitting?

Use browser validation + manual checks:

---

Can I upload files with forms?

Yes! Use FileUploading module and add file to your field:

Learn more: FormsData Module

---

Can I send custom notifications when form is submitted?

Yes, configure in OneEntry admin panel:

• Email notifications to admin/user
• Webhook notifications to your server
• Integration with Events module

---

How do I handle form submission errors?

Always use try/catch

---

Can forms have conditional fields (show/hide based on other fields)?

Not directly in SDK, but you can implement in your UI

---

💡 Important Notes

Forms are Created in Admin Panel

Remember: The SDK is for fetching forms and submitting data, not creating forms.

To create/edit forms: Use OneEntry admin panel or Admin API.

---

Always Validate Data

✅ Client-side validation is not enough:

• Validate on client (better UX)
• Validate on server (OneEntry does this automatically)

---

Handle File Uploads Carefully

✅ Best practices for file uploads:

• Validate file type before upload
• Check file size limits
• Show upload progress
• Handle upload errors

---

🎓 Best Practices

✅ Do's:

• Use markers to reference forms (not IDs)
• Validate data on client and server
• Show loading states during submission
• Provide clear error messages
• Disable submit button after successful submission
• Clear form after successful submission
• Handle file upload errors gracefully
• Use try/catch for error handling

❌ Don'ts:

• Hardcode form IDs in code
• Submit forms without validation
• Ignore error handling
• Allow duplicate submissions
• Upload files without size/type validation
• Show technical errors to users
• Forget to provide user feedback
• Skip loading states
