If you have no previous web experience and have no idea what an FTP Manager is, then this option is not for you.

1. Access your host through the FTP manager

2. Access the plugins directory of your WordPress install /(WordPress directory)/wp-content/plugins/
   If WordPress is installed on the root folder the directory is /wp-content/plugins/

3. Find (or create if not present) the directory titled woocommerce-tm-extra-product-options and upload it and all files within to the directory from the previous step.
4. From your WordPress dashboard, choose Plugins > Installed Plugins
5. Locate the newly added plugin and click on the Activate link to enable its features.

The basic usage of the plugin assigns option fields to a specific product.

Step 1

Add or edit a WooCommerce product.

Step 2

Make sure your product type is either Simple, Variable, Composite, Bookable or Subscription product.

Step 3

Locate the subsection Extra Product Options in the product data panel and click it. You should now be presented with the plugin interface. If you haven't created extra options before for that product you will see the Builder mode.

Builder mode

In this mode you are presented with a Form Builder that you will use to create your options. Click the Add section button to create a section where the options must be placed in. Click the Add element button (cross button) located on the section to select the option field type.

For better understanding of the Form Builder see the section Form Fields Builder.

This method uses the Form Builder to create options that can be set to all of the products, products that belong to specific categories, tags, user roles or specific products.

Step 1

From the WordPress dashboard choose Products > Global Forms.

Step 2

Click the Add Global Form button at the top of the screen.

Step 3

Add title and description for your reference only, so that you can distinguish the different forms.

Step 4

Select the Product Categories that you want your form to be applied on. Choose no categories to apply the form to all products (even to products that don't belong to any category). Clicking the Disable categories checkbox will make the plugin disregard selected categories. You can assign specific products to the form by selecting them on the Products meta box.

Step 5

Add your fields on the Form Fields Builder.

Clicking the settings tab while on the product panel you can override some global settings.

Include additional Global forms

This list contains all of the global forms and checking one will include it on the global. The forms you choose will be displayed alongside with the forms that the product already has. This setting will also override the next one.

Exclude from Global Forms

This will exclude any global forms assigned to this product except those defined in the previous setting.

Override global display

This overrides the global display setting for the display of the fields on the front-end for the current product only. The default value is Use global setting which uses whatever you have chosen on the global settings (see below). Always show will always show the fields assigned to the current product and Show only with an action hook will only show the fields for the current product by using action hooks (see below).

Override Final total box

This will override the global totals box display for this product. The default value is Use global setting which uses whatever you have chosen on the global settings (see below).

Override enabled roles for this product

This will override which roles can see the options for this product.

Override disabled roles for this product

This will override which roles cannot see the options for this product. This setting has priority over the enabled roles one.

Global Forms are applied to all products, products belonging to a specific category or categories or specific products. To gain access to the Global Forms interface from the WordPress dashboard choose Products > Global Forms.

Any existing Global Forms created are displayed in the familiar WordPress table view.

To add a new global form form click the Add Global Form button. This will bring you to the add screen.

Title and Description

These are for your reference only and are not currently being used anywhere in the front-end.

Priority

This is used to determine in which order multiple forms that apply to a specific product are being displayed in the front-end.

Product Categories

They are used to limit the display of your current global product option form on the products that belong to the selected categories. Selecting no categories means that the form will be applied to ALL products.

You can also use logical operators like &&, ||, <, >, <=. >=, !=, ==. The result of those operators is either 1 or 0.

There are four special functions: if, min, max and lookuptable.

If function

The if function has the following format:

if(condition, true, false)

The condition can be condition which can contain global variables or the variables for the current element. The true and false are what the function should output depending on the condition.

min and max functions

The min and max functions has the following format:

min(value1, value2, ...)

max(value1, value2, ...)

The values can contain global variables or the variables for the current element.

lookuptable

This function is used to calculate the value for a lookup table and you can see how you case use it below.

concat function

The concat function has the following format:

concat(value1, value2, ...)

The values can contain global variables or the variables for the current element. If you need to enter a raw string add it in quotes.

Below are the predefined product variables you can use.

{quantity}

Product quantity

{product_price}

Original product price

{dynamic_product_price}

The Dynamic product price is the calculated price for the product from the dynamic element when using the Action mode Set native product Price.

Below are the predefined variables for the current element.

{this.value}

The value of this element converted to a float

{this.text} or {this.rawvalue}

The raw value of this element

{this.value.length} or {this.text.length}

The value length of this element

{this.count}

The number of options the user has selected

{this.count.quantity}

The total quantity of this element

{this.quantity}

The quantity of this element

To target other elements you will need to know the element id or you can just click on the buttons that represent the element.

You will find a selector to choose between the Price of the element, the Value of element, the Quantity of element and the Selected options of element

The format that you enter to target other elements is:

{field.ID.TYPE}

where ID is the element id and TYPE one of the following:

price {field.ID.price}

The price of the targeted element

value {field.ID.value}

The value of the targeted element converted to a float

text {field.ID.text} or rawvalue {field.ID.rawvalue}

The raw value of the targeted element

value.length {field.ID.value.length} or text.length {field.ID.text.length}

The text length of the targeted element

count {field.ID.count}

The number of options the user has selected on the targeted element

count.quantity {field.ID.count.quantity} or quantity {field.ID.quantity}

The total quantity of the targeted element

Below are the special variables you can use.

{options_total}

This is what you would expect to get as an option total when using price types like the percent of price + options. So, that would be the + options part. This total basically includes all options that are not percent of price + options, fixed price + options and don't use a math formula with any of the special variables.

{product_price_plus_options_total}

This is the sum of {options_total} plugin the original product price.

{cumulative_total}

The {cumulative_total} is the total of all other selected options that don't use the {cumulative_total} or {product_price_plus_cumulative_total} variable. However, when multiple addons employ the mathematical variable {cumulative_total} or {product_price_plus_cumulative_total} then each one includes the cost of the preceding ones, but not the subsequent ones.

{product_price_plus_cumulative_total}

This is the sum of {cumulative_total} plugin the original product price.

You can create constants by going to the plugin settings->Math Formula Constants

Click the Add Constant button to create a new constant. Enter the name of the constant in the CONSTANT NAME field and the value of the constant to the CONSTANT VALUE field.

To access a constant in the formula use the following format:

{CONSTANT_NAME}

In general the result of the math formula will not be converted to any currency. Instead the formula results will be the same on any currency used.

However, if you want a number to be converted to converted to the current currency you can enter it in curly braces.

For example the following code will replace {10} with the current currency for 10

{10}/{quantity}

To gain access to the Lookup table interface from the WordPress dashboard choose Extra Product Options > Lookup tables.

Any existing Lookup tables created are displayed in the familiar WordPress table view.

To add a new table click the Add Lookup table button. This will bring you to the add screen.

Click the Import CSV button to import a csv file.

After selecting a valid csv file you should be seeing the importable table.

Clicking the Import CSV button again will override the current table.

The CSV file has some specifications in order to work with the plugin.

• The top left cell is reserved for the table name and should contain at least one character that is not a number. Table names are case-sensitive.
• After the table name the rest of the first row is for the values of the X axis.
• The first column after the table name is for the Y axis values.
• You can add more lookup tables on a single csv file. You can add the next table following the same formatting rules after the table is finished.

Here is CSV with one table:

Here is CSV with two tables:

Lookup tables can be used directly as a price type on the supported elements or as a function for the math formula price type.

Using as a price type

You will need to create one element where you will apply the price of the lookup table. Depending on how you want to use the lookup table you will need two more fields, one more or none.

Using two fields for X and Y axis

After you create the two fields you want to use for the X and Y axis find and write down their unique ids. Those can be found when you edit the element on the top right conrner.

Edit the element you want to apply the pricing for the lookup table and set its price type to "Lookup table".

You should now see three more fields below the price types: "Lookup table", "Element ID for x" and "Element ID for y".

Lookup table

This is a list of all the lookup tables you have imported. The number next to the table name inside the parenthesis is the table index in case you have multiple tables with the same name.

Element ID for x

This is where you will paste the id of the element you want to use for the X axis.

Element ID for y

This is where you will paste the id of the element you want to use for the Y axis.

Using one field only for the X axis

After you create the field you want to use for the X axis find and write down its unique id. This can be found when you edit the element on the top right conrner.

Edit the element you want to apply the pricing for the lookup table and set its price type to "Lookup table".

You should now see three more fields below the price types: "Lookup table", "Element ID for x" and "Element ID for y".

Lookup table

This is a list of all the lookup tables you have imported. The number next to the table name inside the parenthesis is the table index in case you have multiple tables with the same name.

Element ID for x

This is where you will paste the id of the element you want to use for the X axis.

Element ID for y

Leave this setting blank.

Using no fields

Edit the element you want to apply the pricing for the lookup table and set its price type to "Lookup table".

You should now see three more fields below the price types: "Lookup table", "Element ID for x" and "Element ID for y".

Lookup table

This is a list of all the lookup tables you have imported. The number next to the table name inside the parenthesis is the table index in case you have multiple tables with the same name.

Element ID for x

Here you can add any math formula variables like {quantity} or {product_price}. You can also target fields like {field.ID.TYPE} where ID is the element id and TYPE is text, value, value.length, count or count.quantity just like in the math formula.

Element ID for y

Leave this setting blank if you want to use one the X axis or fill it in the same as the previous setting.

Using on the math formula

The function of the math formula to use the lookup table is lookuptable.

lookuptable(field, lookupTable)

field

This is used to target the field for the X axis or the fields for X and Y axis.

You can use any variables that you can use in the formula eg {field.ID.TYPE}.

If you want to set both X and Y axis you must use the array format eg [{field.ID1.text}, {field.ID2.text}].

lookupTable

This is to select the lookup table you want to use.

You should enter the table name in quotes eg 'Table 1'

If the table is not unique you should use the array format and indicate the index of the table eg ['Table 1', 0] where 0 in this case is the table index. Indexes always start with the 0 as the first one. If you have 3 tables with the same name the first one has index 0, the second 1 and the third 2.

A random example:

lookuptable([{field.62e7147c6016e3.03696600.text}, {field.62e714816016f8.90822228.text}], ["table 1", 0])

This example uses the text of the element with ID 62e7147c6016e3.03696600 for the X axis, the text of the element with ID 62e714816016f8.90822228 for the Y axis and for the table it use the first one name table 1.

To correctly do this make sure to place the following code, preferably before the header is rendered.

function tm_epo_js_loader(){
	do_action( 'woocommerce_tm_epo_enqueue_scripts');
}
add_action( 'wp_enqueue_scripts', 'tm_epo_js_loader' );

2. Displaying the fields.

Now it is time to display your fields. Find out where on your code you want to display them and use one of the provided action hooks. For example:

if (isset($post) && is_object($post) && ($post instanceof WP_Post )){
	do_action("woocommerce_tm_epo",$product_id);
}

To get started, you will need WPML and add-on Plugins i.e. the core WPML Multilingual CMS which is always required and the String translations add-on.

Guide for installing & activating WPML is available on the WPML getting started guide.

1. Go to the "Global Forms" list interface.

Here you can see the translations of all the global forms. Right to the form's name. If a translation is not present you will see a cross (+) link to add the translation to the corresponding language else you will see the edit (pencil) icon indicating that a translation is already created.

2. Click the cross (+) link of the language you want to add.

3. Go to the form editor to edit the strings.

Please note that in this interface not all builder elements are activated. Only translatable strings are enabled.

1. Make sure the product in the original language has a builder you want to translate.

Translated products use the form builder of the original created product.

2. Translate the product first.

You can use the WooCommerce Multilingual to do the translation but for the next step you must set the "Product Translation Interface" to "Go to the native WooCommerce product editing screen".

3. Go to the form editor to edit the strings.

After you have translated the product edit it again and the builder will be available. Please note that in this interface not all builder elements are activated. Only translatable strings are enabled.
