You will be granted numerous options to customize the ordering pages, including the division into one or two pages and choose the page layout.
If integrated with Lagom WHMCS Client Theme, your order pages will boost with some extra, eye pleasing, options.

Do not hesitate, just take a closer look at the screenshots and their descriptions to get clear directives and tips.

Extracted files in your WHMCS directory should look like this:

The file is located in 'modules/addons/LagomOrderForm/license_RENAME.php'. Rename it from 'license_RENAME.php' to 'license.php'.

Enter your license key between quotation marks as presented on the following screen. You can find your license key in our client area → 'My Products'.

This folder is available at 'your_whmcs/modules/addons/LagomOrderForm/'.

Open the 'htaccess' file, you will find it in the main root directory.

   RewriteBase /
   
   #one-step-order
   RewriteRule ^order/(.*)$ order.php?m=OneStepOrder&gid=$1 [L]

Otherwise, create the below rule above the WHMCS rules:

  RewriteBase /
 
  #one-step-order
  RewriteRule ^order/(.*)$ order.php?m=OneStepOrder&gid=$1 [L]

If you are using an nginix server, it is advised to add the below lines into its configuration file. Otherwise, the module might not work properly.

 location /order {
   rewrite ^/order/(.*)$ /order.php?m=OneStepOrder&gid=$1 break;
 }

Remember to adjust the above example to your WHMCS location.

Log in to your WHMCS admin area and proceed to 'System Settings' → 'Addon Modules'.
Afterward, find 'Lagom One Step Order Form' and press the 'Activate' button.

To do so, click on the 'Configure' button, tick checkboxes to assign desired admin roles.

• One Step
• Two Steps
• Step by Step* (available soon)
  

For detailed description with visualization in the client area look below.

Note that at the beginning of the ordering process your client will be able to switch between different product packages within a specific product group.

Client area view:

Note: It is not possible to switch between products if this order form type is selected.

Client area 'Step 1' view:

There are two possibilities to choose from:

• Sidebar
• Bottom
  

Underneath you will find details of every possible choice with its visualization in the client area.

• Package Slider - decide whether you would like to use a slider to view the content of a product group that contains more than three packages in the case of the 'Sidebar' order layout,
  and more than four packages in the case of the 'Bottom' order layout.

• Simplified Summary - if enabled, the "Order Summary" box displays only 'Totals' and 'Total Due Today' values.
  It will not display any details about added products, domains or addons.

• Display Price Suffix - if enabled, the currency suffix is shown next to the price.
  However, it is important to previously configure the currency and its suffix details in your WHMCS admin area settings, based on their video tutorial

• Show Domain Spotlights - allows you to display "Spotlight TLDs" which have been previously configured in WHMCS settings.

• Display Navigation Tabs - option is enabled, the additional navigation tabs are shown below the main header title.

1. Upload a new icon in the "Icon Library" section

Important: It is possible to use the Lagom One Step Order Form For WHMCS module without the Lagom WHMCS Client Theme. The module remains fully usable and all available features are supported when the standard WHMCS "Twenty-One" theme is used.
The only limitation concerns the number of supported styles and their color schemes. For "Twenty-One" theme, the "Modern" style with "blue" color scheme is used by default and there are no extra options to choose from.

Take a look below to see how such ordering pages may look like.

Here you can see an example of a "One Step" order form view with the 'Package Slider' option turned on, 'Sidebar' order form layout and 'Default' package type.

In this option, the first steps is dedicated to selecting product packages:

If you want to change the WHMCS module language, go to the following folder:

  /modules/addons/LagomOrderForm/langs

Copy english.php file and rename the newly copied directory with your desired language, for example italian.php. Then, open your personalized file now and replace particular sentences.

The language file english.php is uncoded and can be freely modified. However, it is advised not to change this file itself, it is recommended to use overrides.

• Open the overrides within the ~/lang/ directory.
• Next, create or copy the language file you are going to change. If you want to, for example, create an override for the English language, you will have to create the following directory:

 ~/lang/overrides/english.php.

• Open the just created file to edit its content.
• At the top of the file you must point the used code, for example: <?php for PHP code.
• Change the file content according to your needs. You may enter only single variables to be overridden or change all the lines in the language file.

For example:

~/lang/english.php:

$_LANG['order_new_product'] = 'You’re almost there! Complete your order';

~/lang/overrides/english.php:

 $_LANG['order_new_product'] = 'Complete the order';

Linking to WHMCS with additional URLs is supported by the module, yet only the two below formats are allowed, make sure you do not use any other format:

&promocode:

2. promocode/testcode

&billingcycle:

1. ?billingcycle=annually
2. billingcycle/annually

&addons:
