我有以下两个php文件，我试图将所选选项中的值传递给基本php文件，并根据传递的文件显示信息。

如果我将网址：“fkm_display.php？app = $ app_selected”改为 url：“fkm_display.php”，当我点击提交时，我会收到enitre db信息，我不知道不想要。我只需要与所选应用程序相关的信息。
答案 0 :(得分：0)
我不确定，你的实际问题是什么。可能是您的jQgrid网址格式不正确。你需要这样改变，
url: "fkm_display.php?app="+app_selected,
由于你的app_selected是一个javascript变量而不是php变量。在您的服务器端，您需要获得这样的值，
$app = $_GET['app'];
但是你在php代码中使用的是$app = $_GET['app_selected'];。因为您在jQgrid代码中将app_selected的值设置为app变量。希望这会有所帮助。
