我有以下代码,我用于Android应用程序:
package com.authorwjf.e_notifications;
import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
public class Main extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Bitmap bm = Bitmap.createScaledBitmap(BitmapFactory.decodeResource(getResources(), R.drawable.avatar),
getResources().getDimensionPixelSize(android.R.dimen.notification_large_icon_width),
getResources().getDimensionPixelSize(android.R.dimen.notification_large_icon_height),
true);
Intent intent = new Intent(this, Main.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 01, intent, Intent.FLAG_ACTIVITY_CLEAR_TASK);
Notification.Builder builder = new Notification.Builder(getApplicationContext());
builder.setContentTitle("This is the title");
builder.setContentText("This is the text");
builder.setSubText("Some sub text");
builder.setNumber(101);
builder.setContentIntent(pendingIntent);
builder.setTicker("Fancy Notification");
builder.setSmallIcon(R.drawable.ic_launcher);
builder.setLargeIcon(bm);
builder.setAutoCancel(true);
builder.setPriority(0); …我试图在表格单元格中进行一个简单的输入按钮居中对齐.
我的标记是:
<table width="500" border="1">
<tr>
<td width="390">XXXXXXXXX</td>
<td width="110" rowspan="2" valign="middle"><input type="button" value="submit"></td>
</tr>
<tr>
<td>YYYYYYYY</td>
</tr>
</table>
<br /><br />
<div style="width:500px;">
<div style="float:left;width:390px;">
<div>XXXXXXX</div>
<div>YYYYYYY</div>
</div>
<div style="vertical-align:middle;width:110px;float:right;">
<div><input type="button" value="submit"></div>
</div>
</div>可以在这里查看:
我已经做了一个表格版本,显示了我想要实现的布局.请注意,由"XXXXX"或"YYYYYY"表示的文本具有可变长度.
我正在通过切换到PDO来更新我的应用程序.我有以下代码:
$stmt = $db->prepare("select * from `product` where productid in (:productidLst)");
$stmt->bindParam(":productidLst",$productidLst, PDO::PARAM_INT);
$stmt->execute();
在上面的代码之后,var $ productidLst是1,2我想使用相当于此的PDO:
while($rs=mysql_fetch_assoc($res)){
$rs['qty']=$_SESSION['basket'][$rs['productid']];
$rs['total'] += $rs['qty']*$rs['price'];
$total += $rs['total'];
$a[] = $rs;
}
我已经尝试了很多组合,但没有成功,所以任何帮助这将是赞赏(在第二个代码块$ res是sql).其次我已将参数$ productidLst设置为INT这是正确的还是应该是字符串？
-------------------- UPDATE 1 ---------------------------- ------------------------
我试过以下代码:
$stmt = $db->prepare("select * from `product` where productid in (:productidLst)");
foreach ($stmt->execute(array(':productidLst' => $productidLst)) as $row)
{
$total += $row['total'];
}
返回:为foreach()错误提供的参数无效
我正在使用Laravel 5,我正在尝试将类别变量输出到视图,但目前我收到一个未定义的变量错误.
这是代码.
首先在config/app.php中:
'App\Providers\AppServiceProvider',
在app/Providers/AppServiceProvider.php中:
public function boot()
{
View::composer('partials.menu', function($view)
{
$view->with('categories', Category::all());
});
}
在partials/menu.blade.php中:
<ul>
<li>Home</li>
@foreach($categories as $category)
<li><a href="/store/category/{!! $category->id !!}">{!! $category->name !!}</a></li>
@endforeach
<li>Basket</li>
<li>Checkout</li>
<li>Contact Us</li>
</ul>
并在store/products.php中:
@include('partials.menu')
我得到的确切错误是:未定义的变量:类别任何帮助解决这个将不胜感激.
谢谢
我有以下 htaccess 文件：
RewriteCond %{HTTPS} on
RewriteCond %{REQUEST_URI} !ssl
....// lots of rewrite rules
RewriteCond %{SERVER_PORT} ^443$
RewriteCond $1 !^ssl
RewriteRule (.*) http://www.mydomain.com/$1 [R,L]
RewriteCond %{SERVER_PORT} ^80$
RewriteCond $1 ^ssl
RewriteRule (.*) https://www.mydomain.com/$1 [R,L]
基本上，当我加载安全页面时，我会加载很多不安全的图像和 js，我该如何修改我的 htacccess 以安全加载此内容。
请注意，图像和 js 的文件夹是
/js
/images
并且安全内容是从 /ssl 提供的
谢谢
