通过使用 WordPress + GravityForms 并优化 iPad 显示器的 css，我创建了一个“网络应用程序”供销售人员在他们的 iPad 上使用。使用插件“Gravity Forms PDF Extended”，我能够将捕获的数据输出到我们的服务合同 PDF 之一（我在 Photoshop 中打开 PDF 并使背景透明并将其保存为 gif），但我似乎无法使用 if/elseif/else 语句。我必须将所有 0 值设置为 0，并用一条线穿过它们以使它们显示出来，否则选择了 0 的产品不包含在数组中。
这是我正在填写的图片。红点是变量需要根据基本包更改的地方。请查看我的代码并告诉我为什么它不起作用。这是在没有打印* *_sensor_quantity_adjusted 变量的情况下可以正常工作的完整代码。当我执行 if ($base_package = "Security & Life Safety" {$base_package = "TESTING";} 之类的操作时，它将成功地将基本包的名称更改为 TESTING。但是，如果我做一些像 if ($ base_package = "Security & Life Safety" {$door_sensor_quantity = "TESTING";} 它会抛出一个错误说：
警告：DOMDocument::loadHTML() [domdocument.loadhtml]: htmlParseEntityRef：实体中没有名称，行：/home/username/public_html/newsite/wp-content/plugins/gravity-forms-pdf-extended/render_to_pdf 中的 110。 php on line 70 Unable to stream pdf: headers already sent
当我尝试修改任何产品数量时，关于为什么会发生这种情况的任何想法？
此外，当我取消注释 print_r 时，总计也没有通过，但这是一个完全独立的问题。
