Postcode Lookup

Address Finder

Installation

This integration works by adding our Address Validation tools using JetFormbuilder's form editor. Below are the instructions to add Postcode Lookup or Address Finder.

Create Address Inputs

Add address input fields to your form. A basic address form to capture a correct UK address should have the following fields:

• Address line one (required)
• Address line two
• Address line three
• Post town (required)
• Postcode (required)

You can optionally include additional fields, which are documented in the PAF documentation page.

Add Address Finder

Install and Initialise Plugin

Add a HTML block and include two script tags at the bottom of your form to load the plugin and then to initialise it.

<script 
src="https://cdn.jsdelivr.net/npm/@ideal-postcodes/address-finder-bundled@2/dist/address-finder.js"></script>

<script>
  IdealPostcodes.AddressFinder.setup({
    apiKey: "ak_test",
    outputFields: {
      line_1: 'input[name="line_1"]',
      line_2: 'input[name="line_2"]',
      line_3: 'input[name="line_3"]',
      post_town: 'input[name="post_town"]',
      postcode: 'input[name="postcode"]',
    },
    onLoaded: function () {
      // This prevents the Address Finder from being in obscured by the default
      // JetFormbuilder styles
      this.view.container.parentElement.parentElement.style.overflow = 'visible';
    }
  });
</script>

caution

Take special care to:

1. Insert your API Key in the apiKey field
2. Match the names of your target fields to the JetFormbuilder Form field name. If your Address Line One has the Form field name line_1, ensure that line_1 reads 'input[name="line_1"]'
3. Ensure inputField points to the same field as line_1 to have the Address Finder appear there

If you wish to add an additional field, include the parameter name from our documentation. For instance, adding a county field with name county will look like:

outputFields: {
  line_1: 'input[name="line_1"]',
  line_2: 'input[name="line_2"]',
  line_3: 'input[name="line_3"]',
  post_town: 'input[name="post_town"]',
  county: 'input[name="county"]',
  postcode: 'input[name="postcode"]'
}

Add Postcode Lookup

Layout

Add address input fields to your form. Ensure you have an input field at the top, which will be the field to search for the postcode. This should be followed by a HTML block. Copy the following to the HTML block:

<div id="idpc"></div>

Your layout should be in the following order:

• Postcode search
• HTML block
• Address line one (required)
• Address line two
• Address line three
• Post town (required)
• Postcode (required)

Initialise Postcode Lookup

At the bottom of your form, add another HTML block, ensuring the following scripts are included:

<script 
  src="https://cdn.jsdelivr.net/npm/@ideal-postcodes/postcode-lookup-bundled@2.3/dist/postcode-lookup.js">
</script>

<script>
  IdealPostcodes.PostcodeLookup.setup({
    context: '#idpc',
    input: '#idpc_input',
    apiKey: "ak_test",
    selectClass: 'jet-form-builder__field select-field',
    outputFields: {
      line_1: 'input[name="line_1"]',
      line_2: 'input[name="line_2"]',
      line_3: 'input[name="line_3"]',
      post_town: 'input[name="city"]',
      postcode: 'input[name="postcode"]'
    }
  });
</script>

caution

Take special care to:

1. Insert your API Key in the apiKey field
2. Match the names of your target fields to the JetFormbuilder Form field name. If your Address Line One has the Form field name line_1, ensure that line_1 reads 'input[name="line_1"]'
3. Ensure button, input and selectContainer matches the ids of the lookup button, lookup field and address dropdown container in the fields created in Step 2
4. Ensure the context string matches the id of the last <div>. E.g. if <div id="idpc"></div>, the line of code should read context: "#idpc"

If you wish to add an additional field, include the parameter name from our documentation. For instance, adding a county field with name county will look like:

outputFields: {
  line_1: 'input[name="line_1"]',
  line_2: 'input[name="line_2"]',
  line_3: 'input[name="line_3"]',
  post_town: 'input[name="post_town"]',
  county: 'input[name="county"]',
  postcode: 'input[name="postcode"]'
}
