如何在codeigniter 3.0.1中上传多个文件.stackoverflow中有类似的问题和解决方案,但不幸的是,它们没有帮助解决我面临的问题.

这是出现You did not select a file to upload在我当前代码中的错误消息

如何通过$val->id在Laravel URL参数.我使用以下代码.它的返回错误

如何使用 brozot / Laravel-FCM 在推送通知上添加图像？

我正确发送通知，但我想知道如何发送带有通知的图像？

我尝试了这段代码但不起作用

        $pushData = ['body' => $message, 'title'=>$title,'image'=>'image-url'];




    $pushJsonData = json_encode($pushData);
    if(count($tokens)>0)
    {


        $optionBuilder = new OptionsBuilder();
        $optionBuilder->setTimeToLive(60*20);

        $notificationBuilder = new PayloadNotificationBuilder($title);
        $notificationBuilder->setClickAction('NOTIFICATION');
        $notificationBuilder->setBody($message)->setSound('default');
        $notificationBuilder->setTag(strtotime("now"));


        $dataBuilder = new PayloadDataBuilder();
        $dataBuilder->addData(['a_data' => $pushJsonData]);

        $option = $optionBuilder->build();
        $notification = $notificationBuilder->build();
        $data = $dataBuilder->build();


        $downstreamResponse = FCM::sendTo($tokens, $option, $notification, $data);

        $downstreamResponse->numberSuccess();
        $downstreamResponse->numberFailure();
        $downstreamResponse->numberModification();

        //return Array - you must remove all this tokens in your database
        $downstreamResponse->tokensToDelete();

        //return Array (key : oldToken, value : new token - you must …

当我拉或推到 bitbucket 存储库时，我的 git 有问题。我总是收到这个错误：

致命：无法访问“ https://myrepo@bitbucket.org/****/** ”：无法连接到 bitbucket.org 端口 443：连接超时

我尝试了所有解决方案，但无法解决。

这是我的代码部分:

for( $i = $aKeys['iStart']; $i < $aKeys['iEnd']; $i++ )
{
        $aData = $this->aProducts[$aProducts[$i]];

        $content .= '"'.$aData['sName'].'"';

        if ($i < $aKeys['iEnd'])  
        {
           $content .= ', '; 
        } 
        $i2++;
} 

完整的代码给我这个结果:

["word1", "word2", "word3", ] 

这是一个简单的数组,我将使用它,但这不起作用,因为在word3之后有一个逗号.如何写这个if语句得到如下结果:["word1", "word2", "word3"]？
