I'm working with the WordPress Traveler theme. In the Tour option, there is a slider used for Max People. Max People will be used for another purpose and should work with a precision of 0.1 instead of integers. To achieve this, I made changes in the files: wp-content\plugins\traveler-code\st-option-tree\includes\ot-functions-option-types.php and wp-content\plugins\st-option-tree\includes\ot-functions-option-types.php. I modified the ot_type_numeric_slider function: function ot_type_numeric_slider($args = array()) { extract($args); // phpcs:ignore // Check for description. $has_desc = !empty($field_desc); // Min, max, step options. $_options = explode(',', $field_min_max_step); $min = isset($_options[0]) ? floatval($_options[0]) : 0; $max = isset($_options[1]) ? floatval($_options[1]) : 100; $step = isset($_options[2]) ? floatval($_options[2]) : 0.1; // Format setting outer wrapper. echo '<div class="format-setting type-numeric-slider ' . ($has_desc ? 'has-desc' : 'no-desc') . '">'; // Description. echo $has_desc ? '<div class="description">' . wp_kses_post(htmlspecialchars_decode($field_desc)) . '</div>' : ''; // Format setting inner wrapper. echo '<div class="format-setting-inner">'; echo '<div class="ot-numeric-slider-wrap">'; echo '<input type="hidden" name="' . esc_attr($field_name) . '" id="' . esc_attr($field_id) . '" class="ot-numeric-slider-hidden-input" value="' . esc_attr($field_value) . '" data-min="' . esc_attr($min) . '" data-max="' . esc_attr($max) . '" data-step="' . esc_attr($step) . '">'; echo '<input type="text" class="ot-numeric-slider-helper-input widefat option-tree-ui-input ' . esc_attr($field_class) . '" value="' . esc_attr($field_value) . '" readonly>'; echo '<div id="ot_numeric_slider_' . esc_attr($field_id) . '" class="ot-numeric-slider"></div>'; echo '</div>'; echo '</div>'; echo '</div>'; } So I changed below part: $_options = explode(',', $field_min_max_step); $min = isset($_options[0]) ? $_options[0] : 0; $max = isset($_options[1]) ? $_options[1] : 100; $step = isset($_options[2]) ? $_options[2] : 1; To: $_options = explode(',', $field_min_max_step); $min = isset($_options[0]) ? floatval($_options[0]) : 0; $max = isset($_options[1]) ? floatval($_options[1]) : 100; $step = isset($_options[2]) ? floatval($_options[2]) : 0.1; After implementing these changes, the slider still operates with integers. I don't see anything else related to the slider in this file, and the support mentioned that the changes should be made only in this file. What could have gone wrong?
