如何在没有ID的情况下显示项目的描述

Question

我的代码是这样的：

$conn = new mysqli($dbhost,$dbuser,$dbpass,$db) or die("Connect Failed: %s\\n". $conn-\>error);

    $category=$_POST['category'];
    
    if($category==1)
    {
        $RetStockPHP="SELECT id, CONCAT(imei,', ',brand,', ',model) AS Eqname FROM tbl_equipment";
        if($res1=mysqli_query($conn,$RetStockPHP))
        {
            if(mysqli_num_rows($res1)>0)
            {
                while($row1=$res1->fetch_assoc())
                {
                                
                    $idPHP1=$row1['id'];
                    $EqnamePHP1=$row1['Eqname'];
                    echo "<option value='$idPHP1'>$EqnamePHP1</option>";
                    
                }
            }
        }
    }
    else
    {
        $RetStockPHP="select it.id as itemcode, concat(art.description,', ',it.description,', ',ut.description) as fitem , category from ref_item as it left join ref_article as art on it.article_id = art.id left join ref_unit as ut on it.unit = ut.id order by it.id;";
        if($res1=mysqli_query($conn,$RetStockPHP))
        {
            if(mysqli_num_rows($res1)>0)
            {
                while($row1=$res1->fetch_assoc())
                {
                    $ItemcodePHP1=$row1['itemcode'];
                    $fitemPHP1=$row1['fitem'];
                    echo "<option value='$ItemcodePHP1'>$fitemPHP1</option>";
            
                }
            }
        }
    }

耗材的结果如下：

2|圆珠笔，蓝色，2mm 笔尖，盒子

和设备的结果如下：

20220010201|IMEI-12345、ASUS、VIVOBOOK 14。 code>
