php - 从数据库检索数据并分解并基于该选择复选框

Question

我正在从 MySQL 数据库检索数据并分解它，根据结果我想选择多个复选框，我粘贴我的 PHP 代码和所有复选框代码以及数据库，以便您可以看到必须根据以下情况选择哪个复选框结果。

<?php 
    $query25 = "SELECT * FROM es_availability_options WHERE es_id='4'"; 
    $result25 = @mysql_query($query25);
    echo mysql_error();
    $row25=@mysql_fetch_array($result25);
    $availability_options = $row25['availability_options'];
    $availability_options = explode(', ', $availability_options);

?>

<div class="row">

     <div class="col-md-4">

        <p style="font-size:16px;"><input name="availability_options[]" type="checkbox" value="Available by appointment"> Available by appointment</p>
        <p style="font-size:16px;"><input name="availability_options[]" type="checkbox" value="Pre bookings preferred but can be available at short notice"> Pre bookings preferred, but can be available at short notice</p>
        <p style="font-size:16px;"><input name="availability_options[]" type="checkbox" value="Flexible hours by appointment"> Flexible hours by appointment</p>
        <p style="font-size:16px;"><input name="availability_options[]" type="checkbox" value="Available for overseas travel"> Available for overseas travel</p>
    </div>

    <div class="col-md-4">
        <p style="font-size:16px;"><input name="availability_options[]" type="checkbox" value="Available 7 days"> Available 7 days</p>
        <p style="font-size:16px;"><input name="availability_options[]" type="checkbox" value="12 hours notice required"> 12 hours notice required</p>
        <p style="font-size:16px;"><input name="availability_options[]" type="checkbox" value="Available outside my city only"> Available outside my city only</p>
    </div>

    <div class="col-md-4">
        <p style="font-size:16px;"><input name="availability_options[]" type="checkbox" value="Available 24 hours"> Available 24 hours</p>
        <p style="font-size:16px;"><input name="availability_options[]" type="checkbox" value="24 hours notice required"> 24 hours notice required</p>
        <p style="font-size:16px;"><input name="availability_options[]" type="checkbox" value="Available on weekends only"> Available on weekends only</p>
    </div>

</div><!-- end row -->

我在数据库列“availability_options”中设置了“7 天可用，需要提前 12 小时通知，仅在我的城市之外可用”这些选项。

你几乎已经完成了。只需将 in_array() 与您的表单一起使用，如下所示 -

 <div class="row">

 <div class="col-md-4">

    <p style="font-size:16px;"><input name="availability_options[]" type="checkbox" value="Available by appointment"> Available by appointment</p>
    <p style="font-size:16px;"><input name="availability_options[]" type="checkbox" value="Pre bookings preferred but can be available at short notice"> Pre bookings preferred, but can be available at short notice</p>
    <p style="font-size:16px;"><input name="availability_options[]" type="checkbox" value="Flexible hours by appointment"> Flexible hours by appointment</p>
    <p style="font-size:16px;"><input name="availability_options[]" type="checkbox" value="Available for overseas travel"> Available for overseas travel</p>
</div>

<div class="col-md-4">
    <p style="font-size:16px;"><input name="availability_options[]" type="checkbox" value="Available 7 days" <?php if (in_array("Available 7 days", $availability_options)) {echo "checked"; }?>> Available 7 days</p>
    <p style="font-size:16px;"><input name="availability_options[]" type="checkbox" value="12 hours notice required" <?php if (in_array("12 hours notice required", $availability_options)) {echo "checked"; }?>> 12 hours notice required</p>
    <p style="font-size:16px;"><input name="availability_options[]" type="checkbox" value="Available outside my city only" <?php if (in_array("Available outside my city only", $availability_options)) {echo "checked"; }?>> Available outside my city only</p>
</div>

<div class="col-md-4">
    <p style="font-size:16px;"><input name="availability_options[]" type="checkbox" value="Available 24 hours"> Available 24 hours</p>
    <p style="font-size:16px;"><input name="availability_options[]" type="checkbox" value="24 hours notice required"> 24 hours notice required</p>
    <p style="font-size:16px;"><input name="availability_options[]" type="checkbox" value="Available on weekends only"> Available on weekends only</p>
</div>
