Question

我在下面的代码中创建了一个php表单。即使没有从shoe_sizes或color_value中选择任何内容，我也无法弄清楚如何使输出文件具有PartColor：行。

目前它将所有大小的行添加到输出文件中，即使没有数据但是在没有选择时没有添加PartColor：行。

            foreach ($data['Saleslead']['style_numbers'] as $key => $value) {
                $comma_delmited_list .=   "---- Start Product ----\n"; 
                $comma_delmited_list .=   "\n";

                $color_value = $data['Saleslead']['colors'][$key];
                $shoe_sizes = $data['Saleslead']['shoe_sizes'][$key];
                $part_number = $style_number_complete_list[$data['Saleslead']['style_number_id'][$key]]['name'];
                $color_range = $style_number_complete_list[$data['Saleslead']['style_number_id'][$key]]['color_range'];
                $comma_delmited_list .=   "PartNumber: ".$part_number."\n";  
                $comma_delmited_list .=   "PartColorRange: ".$color_range."\n";  

                if($shoe_sizes != "" || $color_value != ""){
                    $texttoshow = "";
                    if($shoe_sizes != "" && $color_value != ""){
                        $texttoshow = $shoe_sizes;
                    }else if ($shoe_sizes != "" && $color_value == ""){
                        $texttoshow = $shoe_sizes;
                    }else if ($shoe_sizes == "" && $color_value != ""){
                        $texttoshow = $color_value;
                    }
                    $comma_delmited_list .=   "PartColor: ".$texttoshow."\n";  
                }

                $comma_delmited_list .=   "cur_UnitPriceUserEntered: ".$data['Saleslead']['unit_price'][$key]."\n";  
                $comma_delmited_list .=   "OrderInstructions: ".$data['Saleslead']['order_instruction'][$key]."\n";  
                $comma_delmited_list .=   "Size01_Req: ".$data['Saleslead']['small'][$key]."\n";  
                $comma_delmited_list .=   "Size02_Req: ".$data['Saleslead']['medium'][$key]."\n";  
                $comma_delmited_list .=   "Size03_Req: ".$data['Saleslead']['large'][$key]."\n";  
                $comma_delmited_list .=   "Size04_Req: ".$data['Saleslead']['xlarge'][$key]."\n";  
                $comma_delmited_list .=   "Size05_Req: ".$data['Saleslead']['2xlarge'][$key]."\n";  
                $comma_delmited_list .=   "Size06_Req: ".(isset($data['Saleslead']['other'][$key])?$data['Saleslead']['other'][$key]:"")."\n";  
                $comma_delmited_list .=   "\n";
                $comma_delmited_list .=   "---- End Product ----\n"; 
                $comma_delmited_list .=   "\n";

以下是提交表单后的文字内容。

PartNumber：00021

PartColorRange：Darks

cur_UnitPriceUserEntered：21

OrderInstructions：

Size01_Req：21

Size02_Req：

Size03_Req：

Size04_Req：

Size05_Req：

Size06_Req：

我需要PartColor：在PartColorRange下面：

感谢您的帮助！

                } else {
                    $comma_delmited_list .= "PartColor: \n";    
                }

这是因为如果PartColor:或$shoe_sizes不是空的，您只会添加$color_value字符串。如果您希望else显示，则可以在检查它们是否为空之后添加PartColor:块。

if($shoe_sizes != "" || $color_value != "") {
    // your code
} else {
     $comma_delmited_list .= "PartColor: \n";
}

输出
