Question

请指导我在PHP变量的下拉列表中获取所选选项

 Private Sub b_03_Click()    '   Save
    With Sheets("Data").ListObjects(1)
    .ShowTotals = False
    If c_01.ListCount = 0 Then .DataBodyRange.ClearContents
    If c_01.ListCount > 0 Then .DataBodyRange.Resize(c_01.ListCount).Value = c_01.List
    .ShowTotals = True
End With

Hide
End Sub

我需要在<div class="form-group"> <label class="control-label" for="input-order-type"><?php echo $entry_order_type; ?></label> <select name="filter_order_type" id="input-order-type" class="form-control"> <option value=""></option> <option value="<?php echo $filter_order_type; ?>">FB Orders</option> <option value="<?php echo $filter_order_type; ?>">Direct Orders</option> <option value="<?php echo $filter_order_type; ?>">Khathija's Orders</option> <option value="<?php echo $filter_order_type; ?>">Ameer's Orders</option> <option value="<?php echo $filter_order_type; ?>">Saheed's Orders</option> <option value="<?php echo $filter_order_type; ?>">Nada's Orders</option> <option value="<?php echo $filter_order_type; ?>">Henath's Orders</option> <option value="<?php echo $filter_order_type; ?>">Noha's Orders</option> </select> <?php echo $filter_order_type; ?> </div>

中指定所选值

Answer 1

在PHP中完成此操作的唯一方法是按用户提交表单，然后使用$_POST或$_GET变量读取提交的值。这个答案解释如下：https://stackoverflow.com/a/17139538/4264695

您必须使用<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <map class="list-group" name="map"> <area id="section-1" class="list-group-item" shape="rect" coords="0,0,200,200" /> <area id="section-2" class="list-group-item" shape="rect" coords="242,194,393,288" /> <area id="section-2" class="list-group-item" shape="rect" coords="397,24,530,109" /> </map> <img alt="Picture1" src="https://placehold.it/680x466" height="466" width="680" usemap="#map" data-cms="{'contentId':95875}" /> <div class="dropdowntest-content section-1"> <p>Hello world 1</p> </div> <div class="dropdowntest-content section-2"> <p>Hello world 2</p> </div> <div class="dropdowntest-content section-3"> <p>Hello world 3</p> </div>值检查默认值，如下所示。例如，

php

您必须为所有<option value="your_default_value" <?php if(isset($filter_order_type)){ if($filter_order_type == 'your_default_value'){ echo 'selected'; } } ?> >FB Orders</option>设置如下所示，并与您的option值进行比较，并使用默认值进行检查。

我使用表单提交用户选择的内容。当用户提交表单时，将发布所选值并将其带入变量$entry_order_type。我想这就是你所期待的。希望能帮助到你。：）

<?php
$entry_order_type ="Select order type from the list and press the submit button";
if(isset($_POST['filter_order_type'])){
   $entry_order_type = $_POST['filter_order_type'];  // Storing Selected Value In Variable
}
?>
<form action="#" method="post">
<div class="form-group">
    <label class="control-label" for="input-order-type"><?php echo $entry_order_type; ?></label>

    <select name="filter_order_type" id="input-order-type" class="form-control">

      <option value=""></option>

      <option value="FB Orders" <?php if($entry_order_type=="FB Orders"){echo "selected";} ?> >FB Orders</option>
      <option value="Direct Orders" <?php if($entry_order_type=="Direct Orders"){echo "selected";} ?> >Direct Orders</option>
      <option value="Khathija's Orders" <?php if($entry_order_type=="Khathija's Orders"){echo "selected";} ?> >Khathija's Orders</option>
      <option value="Ameer's Orders" <?php if($entry_order_type=="Ameer's Orders"){echo "selected";} ?> >Ameer's Orders</option>
      <option value="Saheed's Orders" <?php if($entry_order_type=="Saheed's Orders"){echo "selected";} ?> >Saheed's Orders</option>
      <option value= "Nada's Orders" <?php if($entry_order_type=="Nada's Orders"){echo "selected";} ?> >Nada's Orders</option>
      <option value="Henath's Orders" <?php if($entry_order_type=="Henath's Orders"){echo "selected";} ?> >Henath's Orders</option>
      <option value="Noha's Orders" <?php if($entry_order_type=="Noha's Orders"){echo "selected";} ?> >Noha's Orders</option>
    </select>
    <input type="submit" name="submit" value="Get Selected Values" />

</div>
</form>
