Question

我在表单中输入了一个jquery datepicker。它正确显示当前日期作为初始值。我希望此日期选择器显示在提交表单后重新加载页面时选择的日期。但是现在，我只知道如何在value属性中回显当前日期。

这是AppointmentDateSelector.php中的datepicker表单：

<form method="POST">
    <div style='margin:0 auto; text-align:center;'>
        <label>Appointment Date: </label>
        <input type="text" id="datepicker" name="date" value=<?php echo date('m/d/Y');?> />
        <input type="hidden" name="action" value="list_appointments"/>
        <input type="hidden" name="date" value="Value of datepicker goes here?"/>
        <input type="submit" value="Refresh List" name="Update" />
        <br />
    </div>
</form>

和包含它的Scheduling.php页面。

您需要检查日期是否已提交，在这种情况下，请将其用作值：

<input type="text" id="datepicker" name="date" value="<?php echo (isset($_POST['date']) ? $_POST['date'] : date('m/d/Y')); ?>" />

datepicker在表单重新加载后显示选定的值
