$offset not working for pagination codeigniter

I am trying to implement Pagination into my searchresults page. I've asked this question yesterday with no succes Records not limited on searchpage using codeigniter pagination and the problem I have now is a bit different. Situation My pagination links are working and i see the url change like this: http://example.com/home/searchresults/2 (for the second page of pagination) etc. But all the searchresults are shown. When I edit the limit to 1 I get more links, so that's working properly. Question What could be this stupid problem? I think it has to do with my Total_rows My controller: function

自己手动实现远程执行功能

旧时模样 提交于 2019-12-02 09:10:31
在阅读《深入理解Java虚拟机》第二版,一书中。第九章看到的demo。 这个小东西实现的功能,就是让服务器可以在运行时期动态的执行代码,打印日志等, 而不需要修改服务器代码,重启服务器。一开始以为是比较高深的东西,但是实际上,确实不算很难。 书中提供了 5 个类用于动态执行代码。使用了一个 JSP 文件来作为触发执行操作的入口,并且获取程序的执行结果。需要说明的是这5个类以及这个 jsp 文件都是需要放在项目的代码中的。 jsp 文件中的内容就是代用那5个类的代码,去加载临时文件,执行其中的代码,然后将执行的结果显示到页面上 具体执行步骤就是 本地编写好临时代码并且编译成 class 文件 将编译好的 class 文件上传到服务器上的指定位置 访问 jsp 页面,执行代码并且返回代码的执行结果 这个服务器上的指定位置是在 jsp 文件中指定的,这个 jsp 文件就是一个触发加显示的作用,实际上你用一个接口去实现也是可以的。然后这个我觉得是不适合放在生产环境中的,比较有风险。 放上代码: package com . java . test . load ; public class ByteUtils { public static int bytes2Int ( byte [ ] b , int start , int len ) { int sum = 0 ; int end =

Assembly offset calculation rule

天大地大妈咪最大 提交于 2019-12-02 08:42:10
So... the rule of offset calculation states in my course book that: offset = [bp] + [bx] + [di|si] + CONST (any part is optional, but atleast one is required) But reading on the internet i found the rule as : offset = [bp|bx] + [di|si] + CONST Which one is it? And why? (In my opinion the first should be also valid since bx could contain an arbitrary value like (1..F), but i tend to belive I am wrong and there must be a BX or BP) The "internet rule" is correct. You can have 1 base register ( bp or bx ) and 1 index register ( si or di ). You can't have bp + bx or si + di at the same time. See

Pandas: how to merge two dataframes on offset dates?

前提是你 提交于 2019-12-02 08:08:46
问题 I'd like to merge two dataframes, df1 & df2, based on whether rows of df2 fall within a 3-6 month date range after rows of df1. For example: df1 (for each company I have quarterly data): company DATADATE 0 012345 2005-06-30 1 012345 2005-09-30 2 012345 2005-12-31 3 012345 2006-03-31 4 123456 2005-01-31 5 123456 2005-03-31 6 123456 2005-06-30 7 123456 2005-09-30 df2 (for each company I have event dates that can happen on any day): company EventDate 0 012345 2005-07-28 <-- won't get merged b/c

'End(xlDown)' acting weird

不羁岁月 提交于 2019-12-02 07:00:22
I suspect that the .end(xlDown) is acting a bit weird. Dim rfound As Range Set rfound = Columns("B:B").Find(What:=Me.ComboBox1.Value, _ LookAt:=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlNext) If ComboBox1.Value <> "" And WorksheetFunction.CountIf(Range("B:B"), _ ComboBox1.Value) > 0 And rfound.Offset(0, 1).Value <> "" Then rfound.Offset(0, 1).End(xlDown).Offset(1, 0).Value = TextBox1.Value Upon CommandButton1_click , the code will search in the column B for any matched criteria and then OffSet to the right cell provided my conditions are all met. However, it prompt me a message Run

高分一号/二号/六号定标系数

前言 最近忙里抽闲,把焦糖计划的预更新做了一点进度,主要是把最常用的三颗星的定标系数写入静态JSON文本(文末),便于用户控制参数。 IDL中JSON读取 从JSON_PARSE的源码可以看到,IDL中其实可以创建一个IDLffJSON对象,但是帮助文档只字未提,对象的函数方法都不知道,只能老老实实用现成的JSON_PARSE函数,而且这个函数还很友好,支持直接从文件读取JSON信息,还可以返回多种形式。 一点自己的想法 其实对于高分辨率遥感来说,最主要应用的是精细化监测,而定标更多应用于定量反演,太准确的辐射值标定对很多高分用户来说其实跟大气纠正差不多都是鸡肋的。但是对于MODIS,FY这些宽视域,低分辨率的影像来说,就需要将定标工作做好,才能更好地服务近于定量遥感。 高分一号二号六号历年的定标系数 { "GF1" : { "WFV1" : { "2013" : { "gain" : [ 5.8510 , 7.1530 , 8.3680 , 7.4740 ] , "offset" : [ 0.0039 , 0.0047 , 0.0047 , 0.0274 ] } , "2014" : { "gain" : [ 0.2004 , 0.1648 , 0.1243 , 0.1563 ] , "offset" : [ 0.0 , 0.0 , 0.0 , 0.0 ] } , "2015"

Broker Configs Property Default Description broker.id 每个broker都可以用一个唯一的非负整数id进行标识;这个id可以作为broker的“名字”,并且它的存在使得broker无须混淆consumers就可以迁移到不同的host/port上。你可以选择任意你喜欢的数字作为id,只要id是唯一的即可。 log.dirs /tmp/kafka-logs kafka存放数据的路径。这个路径并不是唯一的,可以是多个,路径之间只需要使用逗号分隔即可;每当创建新partition时,都会选择在包含最少partitions的路径下进行。 port 6667 server接受客户端连接的端口 zookeeper.connect null ZooKeeper连接字符串的格式为:hostname:port,此处hostname和port分别是ZooKeeper集群中某个节点的host和port;为了当某个host宕掉之后你能通过其他ZooKeeper节点进行连接,你可以按照一下方式制定多个hosts: hostname1:port1, hostname2:port2, hostname3:port3. ZooKeeper 允许你增加一个“chroot”路径,将集群中所有kafka数据存放在特定的路径下

What is the maximum value for row and column Range offset in VBA/Excel?

白昼怎懂夜的黑 提交于 2019-12-02 05:27:03
I am using microsft excel 2003. I am getting "Application-defined or object-defined error" while executing the following If statement. If Range("MyData").CurrentRegion.Offset(i, 0).Resize(1, 1).Value = Range("MyData").CurrentRegion.Offset(i + 1, 0).Resize(1, 1).Value Then The value of i is 58981 when I get this error. Is there any limit on row offset ? Thanks in Advance. ---Sam excel 2003 worksheets can have a maximum of 65,536 rows (by 256 columns) . i guess your region plus the big offset go over this limit. Do the resize before the offset, that way you won't offset a large region so that it

String源码分析

泄露秘密 提交于 2019-12-02 05:23:28
Class About String In Package Of Java Lang 这篇笔记主要用于分析Java中String系列的源代码。以下是String系列的的类层次结构图。这篇博文主要目的在于分析String系列源码思想、以及String系列类型之间的关系,以及性能等。 第一序 String类型源码解析 String类型是一个final类型,是不允许继承一改变的。 1.持有成员变量 一直疑惑String字符串类型为什么那么类似于字符数组char[ ],分析源码后将会发现,本质就是字符数组。String类型持有私有访问权限的字符数组。 源码:private final char value []; 都发现String中的字符串是连续不可变的,也正说明该value[ ]数组是final类型。同事Java程序中将类似于“abc”这样的字符串编译为String类型的实例对象,至于这个实现细节有待于进一步学习! 同时String类型实现了Serializable序列化标记接口,所以拥有序列化ID。 源码:private static final long serialVersionUID = -6849794470754667710L; String类型持有一个整形,作为hash值。 源码: private int hash ; 2.实例构造器 a.无参构造器 public
