在PHP中检查isset $ POST时如何使用$ _GET

如何解决在PHP中检查isset $ POST时如何使用$ _GET

我有一个带有change-password.PHP？id = 1＆key = 37759的网址

我正在尝试从url和usind的if语句中获取值，但遇到了麻烦。

VSC

但是如果我在它们外面回声，它会像这样：

    render() {
        console.log("sart_azmoon");


        return (
            <View style={{
                backgroundColor: color.khakestarikam,width: '100%',height: '100%',}} >


   

                    <View style={{

                        marginLeft: "4%",marginRight: "4%",marginTop: 5,marginBottom: 30,borderBottomrighTradius: responsiveWidth(3),borderBottomLefTradius: responsiveWidth(3),}}>

                        <View style={{
                            backgroundColor: '#757575',borderTopRighTradius: responsiveWidth(3),borderTopLefTradius: responsiveWidth(3)
                        }}>
                            <Text style={{
                                color: "white",fontFamily: font.font_black,fontSize: responsiveFontSize(2.5),textAlign: "center",marginLeft: responsiveHeight(2),justifyContent: 'center'
                            }}>
                                </Text>
                        </View>
                        <View style={{
                            backgroundColor: 'white',}}>
                            <FlatList
                                // showsHorizontalScrollIndicator={false}
                                showsverticalScrollIndicator={false}
                                contentContainerStyle={{
                                    flexGrow: 1,justifyContent: 'center',alignItems: 'center'
                                }}
                                style={{
                                    width: '100%',backgroundColor: '#fff',marginTop: 4,// backgroundColor: 'yellow',}}
                                // horizontal={true}
                                // keyExtractor={(data) => data.ExamId}
                                data={this.state.GroupList}
                                renderItem={({ item,index }) =>
                                    (

                                        <GroupList
                                            item={item}
                                        />

                                    )
                                }


                            />
                            <View style={{ height: responsiveHeight(5),}} />
                        </View>

                    </View>


                    <View style={{

                        flexDirection: "row",marginLeft: "4%",marginTop: 10,marginBottom: 0
                    }}>
                        <Text style={{
                            color: "#ff4646",textAlign: "left",justifyContent: 'center'
                        }}>
                            ⬤
                        </Text>

                        <Text style={{
                            color: "#757575",fontSize: responsiveFontSize(1.7),marginTop: responsiveHeight(0.5),}}>
                        </Text>
                    </View>

                    <View style={{

                        flexDirection: "row",marginRight: responsiveHeight(4),marginBottom: 80
                    }}>
                        <Text style={{
                            color: "#ff4646",}}>
                        </Text>
                    </View>


                </ScrollView>

            </View>
        );
    }
}

export default start_azmoon;

这也行不通：

if (isset($_POST['password'])) {
        $id = $_GET['id'];
        $key = $_GET['key'];
        echo $key; // this is empty
}

这是此页的完整代码 当用户要求重设密码时，将通过用户在其电子邮件中获得的链接设置change-password.PHP？id = 1＆key = 37759。然后将使用以下代码将他们带到此页面。

$id = $_GET['id'];
$key = $_GET['key'];
echo $key; // I get the value
if (isset($_POST['password'])) {
        
}

请告诉我我在做什么错。谢谢您的帮助！
