call_report_export.blade.php #

$stmt = App\Http\Controllers\CallDetailsController::insertVicidialReportLog($webserver_id,$PHP_AUTH_USER,$PHP_AUTH_USER_ID,$report_name,$query_date,$end_date,$shift,$file_download,$report_display_type);

解决方法 #

方案一：实例化控制器调用方法（快速临时解决） #

直接在Blade中创建控制器实例后调用方法：

$controller = new App\Http\Controllers\CallDetailsController();
$stmt = $controller->insertVicidialReportLog($webserver_id,$PHP_AUTH_USER,$PHP_AUTH_USER_ID,$report_name,$query_date,$end_date,$shift,$file_download,$report_display_type);

方案二：将方法改为静态方法（简单直接） #

修改CallDetailsController.php中的方法，添加static关键字：

public static function insertVicidialReportLog($webserver_id,$authUser,$userId,$reportName,$query_date,$end_date,$shift,$file_download,$report_display_type) { 
    // 原方法代码保持不变
}

修改后Blade中的调用代码无需改动。

方案三：迁移逻辑到服务类（符合Laravel MVC规范） #

视图层应仅负责展示，业务逻辑建议抽离到服务类：

1. 创建服务类app/Services/ReportLogService.php：

namespace App\Services;

use Illuminate\Support\Facades\DB;

class ReportLogService {
    public static function insertVicidialReportLog($webserver_id,$authUser,$userId,$reportName,$query_date,$end_date,$shift,$file_download,$report_display_type) { 
        $LOGip = $_SERVER["REMOTE_ADDR"]; 
        $LOGbrowser = $_SERVER["HTTP_USER_AGENT"]; 
        $LOGscript_name = $_SERVER["SCRIPT_NAME"]; 
        $LOGserver_name = $_SERVER["SERVER_NAME"]; 
        $LOGserver_port = $_SERVER["SERVER_PORT"]; 
        $LOGrequest_uri = $_SERVER["REQUEST_URI"]; 
        $LOGhttp_referer = $_SERVER["HTTP_REFERER"]; 

        $LOGbrowser=preg_replace("/\'|\"|\\\\/","",$LOGbrowser); 
        $LOGrequest_uri=preg_replace("/\'|\"|\\\\/","",$LOGrequest_uri); 
        $LOGhttp_referer=preg_replace("/\'|\"|\\\\/","",$LOGhttp_referer); 

        if (preg_match("/443/i",$LOGserver_port)) {$HTTPprotocol = 'https://';} else {$HTTPprotocol = 'http://';} 
        if (($LOGserver_port == '80') or ($LOGserver_port == '443') ) {$LOGserver_port='';} else {$LOGserver_port = ":$LOGserver_port";} 
        $LOGfull_url = "$HTTPprotocol$LOGserver_name$LOGserver_port$LOGrequest_uri"; 

        $LOGhostname = php_uname('n'); 
        if (strlen($LOGhostname)<1) {$LOGhostname='X';} 
        if (strlen($LOGserver_name)<1) {$LOGserver_name='X';} 

        $insertReportLog = DB::table('vicidial_report_log')->insertGetId([ 
            'event_date' => NOW(), 
            'user' => $authUser, 
            'ip_address' => $LOGip, 
            'report_name' => $reportName, 
            'browser' => $LOGbrowser, 
            'referer' => $LOGhttp_referer, 
            'notes' => "$LOGserver_name:$LOGserver_port $LOGscript_name |$query_date, $end_date, $shift, $file_download, $report_display_type|", 
            'url' => "$LOGfull_url", 
            'webserver' => "$webserver_id", 
        ]); 
        return $insertReportLog; 
    }
}

2. 在Blade中调用服务类方法：

use App\Services\ReportLogService;

$stmt = ReportLogService::insertVicidialReportLog($webserver_id,$PHP_AUTH_USER,$PHP_AUTH_USER_ID,$report_name,$query_date,$end_date,$shift,$file_download,$report_display_type);

方案四：控制器处理逻辑后传值到视图（最规范） #

在渲染视图的控制器方法中完成逻辑调用，将结果传递给视图：

public function exportReport() {
    // 自行获取所需参数$webserver_id、$PHP_AUTH_USER等
    $stmt = $this->insertVicidialReportLog($webserver_id,$PHP_AUTH_USER,$PHP_AUTH_USER_ID,$report_name,$query_date,$end_date,$shift,$file_download,$report_display_type);
    return view('reports.call_report_export', compact('stmt'));
}

此时Blade中直接使用$stmt变量即可，无需在视图内调用方法。
