在Yii2中另一个foreach内部的foreach

Question

我尝试下一个：

syntax error, unexpected 'foreach' (T_FOREACH)

现在我需要添加一个新参数，但是有很多对象，我需要在foreach中使用foreach：

public class WebViewActivity extends Activity {

    private WebView webView;
    private ProgressDialog progress;
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.webview);
        WebView myWebView = (WebView) findViewById(R.id.webView1);
        myWebView.setWebViewClient(new MyWebViewClient());
        myWebView.loadUrl("https://www.example.com");
    }

    private class MyWebViewClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            if (Uri.parse(url).getHost().equals("https://www.example.com")) {
                // This is my web site, so do not override; let my WebView load the page
                return false;
            }
            // Otherwise, the link is not for a page on my site, so launch another Activity that handles URLs
            Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
            startActivity(intent);
            return true;
        }
    }
}

但打印

@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.checklist);
    db = new DatabaseHandlerChecklist(this);
    initList();

                        Toast.makeText(ChecklistActivity.this, "Insert text first !", 2000).show();
                    } else {

如何在foreach中使用gallery的所有元素？

Answer 1

将所有HeaderItem项放入变量中，然后在$post->gallery->galleryMedia变量中使用它。

$json
