Question

我正在购物车中担任产品推荐员，这类似于您去杂货店和冲动糖果时的冲动。

如下所示。当我单击下拉菜单时，它没有包含我要查找的数据。

我正在使用以下代码，我认为它将输入此数据：


                     <?php foreach($Fluoros['Fluoro'] as $Fluoro) {
                     echo $Fluoro['Fluoro'], '<br>';
                     }
                    ?>

                    <select title="Add Fluoro To Your Cart" id="<?php echo $Fluoro['Description']; ?>" class="selectpicker white-drop crimp-part" data-width="auto">

                       <select title="Select Fluoro" id="<?php echo $Fluoros['Product']; ?>" class="selectpicker white-drop crimp-part" data-width="auto">
                       <?php foreach($Fluoros['Product'] as $Fluoro){
                        echo '<option ' . 'value = ' . $Fluoro['Fluoro'] . ' </option>';
                        } 

                        ?>
                        </select> ```

The data is being pulled in my "Cart " class. The Select statement below works and brings the correct results

 ```php 
public function fluoroCart() {
    $getFluoroProducts = $this->_db->query("SELECT i.Part_Number, i.Description
                           FROM Inventory i
                                             INNER JOIN Product_Details pd on pd.Part_Number = i.Part_Number
                                             WHERE pd.Category_ID = 15");

     $fluoroProducts = $this->_db->results();

      foreach($fluoroProducts as $Fluoro){

    $Flouros [] = array( 'Fluoro'=>$Fluoro->Part_Number, 'Description'=>$Fluoro->Description);

      }

    }```

在HTML中，选择选项值需要用引号引起来。另外，除了指示值之外，您还需要在开始和结束选项标签之间放置一些文本，以使其实际显示在菜单中。

<select>
<option value="some value">Some Value Text</option>
</select>

您需要像这样修改PHP

echo '<option value = "' . $Fluoro['Fluoro'] . '">'.$Fluoro['Fluoro'].' </option>';

数据未从For循环中显示
