Proposal Calculator: Resolving Display and Data Retrieval Issues

As a seasoned programmer and technical writer, I've encountered numerous challenges while working with proposal calculators. One common problem arises when template selection fails to display values and categories. In this article, I'll delve into the causes and solutions for this issue, providing insights and technical guidance to enhance the functionality of proposal calculators.

Understanding the Problem

The primary issue with the proposal calculator stems from the code responsible for fetching and displaying data. When a template is selected, the code that retrieves data from the database is not executed correctly. Additionally, the code responsible for displaying data does not consider the selected template, resulting in the display of only a single category and product.

Identifying the Root Cause

After meticulous analysis, the root cause of the problem was identified as the flawed logic for fetching and displaying data. The code for fetching data from the database was not triggered when a template was selected, and the code for displaying data failed to incorporate the selected template's details.

Technical Solution

To resolve this issue, the code that retrieves and displays data needed to be modified. The code for fetching data from the database was modified to execute upon template selection. The code for displaying data was also updated to consider the selected template and display the appropriate values and categories.

Step-by-Step Implementation

The following steps provide a detailed overview of the code modifications:

1. Data Retrieval Modification: The code responsible for fetching data from the database was modified to execute when a template was selected. This ensured that the correct data was retrieved based on the chosen template.
2. Data Display Modification: The code responsible for displaying data was modified to consider the selected template. This ensured that the correct values and categories were displayed according to the selected template.
3. Totals Update: The code was modified to update the totals in the table when the data was changed. This ensured that the totals reflected the changes made to the data.

Code Implementation Example

The following code snippet exemplifies how the modified code would appear:

$(document).on("change", "#template-dropdown", function() {
    var selectedTemplate = $(this).val();
    if (selectedTemplate !== '') {
        fetchTemplateData(selectedTemplate);
    }
});

function fetchTemplateData(templateName) {
    $.ajax({
        type: "POST",
        url: "get_template_data.php",
        data: { template_name: templateName },
        success: function(response) {
            console.log(response);
            var templateData = JSON.parse(response);
            $('#proposal-table tbody').empty();
            templateData.forEach(function(data) {
                var newRow = '<tr>' +
                    '<td>' +
                    '<select name="product_category" class="border border-gray-400 px-4 py-2 text-left w-full">' +
                    '<option value="' + data.product_category + '" selected>' + data.product_category + '</option>' +
                    '</select>' +
                    '</td>' +
                    '<td>' +
                    '<select class="form-select border border-gray-400 px-4 py-2 text-left w-full">' +
                    '<option value="' + data.product_name + '" selected>' + data.product_name + '</option>' +
                    '</select>' +
                    '</td>' +
                    '<td class="px-1 py-2 text-center"><input type="text" class="quantity-input rounded w-16 text-center" value="' + data.product_quantity + '"></td>' +

                    '<td class="px-1 py-2 text-center"><input type="text" class="total-price-with-tax-input rounded w-24 text-center bg-gray-200" readonly></td>' +
                    '<td class="px-1 py-2 text-center"><input type="text" class="discount-input rounded w-24 text-center" value="' + data.product_discount + '"></td>' +

                    '<td class="px-1 py-2 text-center"><input type="text" class="rounded w-20 text-center special-price-input bg-gray-200" readonly></td>' +
                    '<td class="px-1 py-2 text-center"><input type="text" class="rounded w-20 text-center product-power-input bg-gray-200" readonly></td>' +
                    '<td class="px-4 py-2 text-center">' +
                    '<button class="bg-red-500 hover:bg-red-700 text-white font-bold rounded delete-row-btn py-1 px-3 rounded">-</button>' +
                    '</td>' +
                    '</tr>';
                $('#proposal-table tbody').append(newRow);
            });
            fetchCategories($('select[name="product_category"]'));
            fetchProducts($('select.form-select'));
        }
    });
