页面刷新后，保持下拉列表中的值处于选中状态

Question

I'm trying to select value, but when I refresh the page it resets the values.

<div class="clearfix mb-20">

    <div class="col s6 m6 l6">
    <label class="form-label"><?= __('Gender') ?></label>
    <select class="input" name="filter_gender">
    <option value="both" <?= $Schedule->get("filter_gender") == "both" ? "selected" : "" ?>><?= __("Both") ?></option>
    <option value="male" <?= $Schedule->get("filter_gender") == "male" ? "selected" : "" ?>><?= __("Male") ?></option>
    <option value="female" <?= $Schedule->get("filter_gender") == "female" ? "selected" : "" ?>><?= __("Female") ?></option>
    </select>
</div>

Any way to get this fixed?

filter_gender: $form.find(":input[name='filter_gender']").val(),

How do I add gender here?

        $Schedule->set("user_id", $AuthUser->get("id"))
             ->set("account_id", $Account->get("id"))
             ->set("target", $target)
             ->set("speed", \Input::post("speed"))
             ->set("is_active", (bool)\Input::post("is_active"))
             ->set("daily_pause", $daily_pause)
             ->set("end_date", $end_date);

Solution 1: When you select something in your form (select option), you change the url and add the parameters. So using 'onChange' event on your form or form element you can change the url and add the param.

Example: http://www.example.com?my_select_option=any_value

Solution 2: Using cookies, set some cookies with a key 'my_specific_form_filters' and values an object with your selected form elements.

Example: {my_select_option: “any_value”}

Solution 3: Same logic as cookies applies for local storage where you can save data based on key value.

Solution 4: Save in PHP session based also on key value and retrieve when needed.
