Comment créer un calculateur de prix WooCommerce pour produits personnalises

Start with a simple WooCommerce product that represents the custom item being configured. In the demo, the product is named Custom Logo T-Shirt Demo and uses a $24 base price.

The calculator can then collect the product options, calculate the configured price, and pass a readable summary into the WooCommerce workflow.

Keep the main product choices in the same step so the shopper can see the effect of each selection immediately. In the form style settings, apply the Clean cards theme preset, then add a native two-column row: Dynamic Image on the left and product options on the right.

The Dynamic Image item uses its main image field for the default product preview. The variation images are managed later from that same item, in its Image layers table.

This works especially well for custom products because the buyer does not have to move between steps just to compare colors, logos, and pricing.

Create one option group for colors and one Icon Picker for logos. The demo colors are red, yellow, blue, and green. The logo choices are palm, teddy bear, skull, and sun.

Use radio-style behavior for each group so the shopper chooses exactly one color and exactly one logo. This prevents impossible combinations and makes the image logic easier to maintain.

Open the Dynamic Image item from the visual builder. Keep the default red palm T-shirt in the main Image field, then scroll to the Image layers table inside the same item editor.

This table is where the extra variation images are managed. Each row is one image that can appear above the base image when its visibility conditions are true.

For the T-shirt demo, red_palm.png is the base image. The remaining 15 combinations are added as layer rows, such as Blue sun, Green skull, or Yellow teddy.

After clicking the eye icon on a layer row, the plugin opens the layer visibility condition builder. This is the screen that controls when that specific image appears.

For blue_sun.png, leave the operator set to All conditions must be filled. Then add two rows: the Blue color Image item must be selected, and the logo Icon Picker must be equal to Sun.

The logo price is not used to decide which image appears. The Dynamic Image layer checks the selected Icon Picker label, so clear labels such as Palm, Teddy, Skull, and Sun matter.

After the visual choices, add size and quantity controls in a native two-column row. In the demo, M is included, L adds $2, XL adds $4, and quantity uses the $24 product price.

This keeps the total transparent: visual choices can add logo upcharges, size can add production cost, and quantity controls how many units are ordered.

Embed the calculator on a dedicated page or inside the WooCommerce product content. The shortcode below is the demo embed used for this guide.

If the form must write the selected options into WooCommerce order details, open the form settings and enable the WooCommerce summary options you need before publishing.

Test the frontend as a shopper: switch color and logo combinations, check the image, change size, update quantity, and confirm the summary matches the configured product.
