CodeIgniter: Passing Arguments from View to Controller?

EDIT: With the code below now, I am unsure on how to print out the bookmarks and the tags correctly I'm completely new to CI and I have recently hit a road block. I'm very unsure how I would go about passing a function argument from the view file to the controller so I could use it on a function? I have a foreach loop on the view going through the all the items passed by function get

CodeIgniter:将视图中的参数传递给控制器​​?

编辑:现在下面的代码,我不确定如何正确打印书签和标签 我对CI很陌生,最近我遇到了一个障碍。 我很不确定如何将视图文件中的函数参数传递给控制器​​,以便我可以在函数上使用它? 我通过函数get_latest_bookmarks传递的所有项目在视图上有一个foreach循环。 该函数返回一个ID为每个项目,我想与另一个函数称为get_bookmark_tags这将从另一个表中获取书签的标签。 我已经提供了我在下面所做的代码。 模型: <?php

Designing a multiple level user permission system

I am working on a site that has a database schema like a tree. From top to bottom I have: One Company can have many Locations that can have many Fleets that can have many Vehicles The user permission system has to be flexible in that someone can gain or have restricted access at any level of the tree. For example, a person that manages location x will by default have full access to al

设计一个多级用户权限系统

我正在一个拥有像树一样的数据库模式的网站上工作。 从上到下我有: 一家公司可以有很多 可以有很多位置 可以有很多的舰队 汽车 用户权限系统必须灵活,因为某人可以在树的任何级别获得或限制访问。 例如,一个管理位置x的人默认可以完全访问位置x以下的所有车队和位置x以下的所有车辆。 但我也应该能够限制用户访问位置x下的任何节点。 为这种权限系统开发模式的正确方法是什么? 存储用户有权访问的每个节点是

Why this two objects are equal (==)?

In PHP I have two objects, they are different because of the $_frets variable (x is a string "x"), but PHP says ($o1 == $o2) == TRUE. Why? Dump of $o1 : guitarChord Object ( [_guitarChord:guitarChord:private] => [_chord:guitarChord:private] => chord Object() [_baseFret:guitarChord:private] => 0 [_frets:guitarChord:private] => Array (

为什么这两个对象是相等的(==)?

在PHP中,我有两个对象,它们因$ _frets变量而异(x是一个字符串“x”),但PHP说 ($o1 == $o2) == TRUE. 为什么? $o1转储: guitarChord Object ( [_guitarChord:guitarChord:private] => [_chord:guitarChord:private] => chord Object() [_baseFret:guitarChord:private] => 0 [_frets:guitarChord:private] => Array ( [0] => x [1] => 0

PHP image uploads. how do I protect against images containning code?

From what I understand, - images (jpeg, gif etc.) might contain valid php/python/perl etc. code. So - anyone can create file that will be valid jpeg at the same time can be executed by PHP interpreter. (here is description: link) So - I was wondering - is there a way to strip malicious code from images? would recoding images with GD or imagemagic work? Thanks! Actual images will not cont

PHP图像上传。 如何防止包含代码的图像?

根据我的理解, - 图像(jpeg,gif等)可能包含有效的php / python / perl等代码。 所以 - 任何人都可以创建一个有效的jpeg文件,同时可以由PHP解释器执行。 (这里是描述:链接) 所以 - 我想知道 - 是否有办法从图像中去除恶意代码? 会记录与GD或imagemagic工作的图像? 谢谢! 实际图像不包含代码。 但是没有任何东西阻止某人试图获取上传的“图片”文件,然后试着让它执行。 应该设置你的解释器(Perl,PHP等),

Why does the PHP version run faster than MySQL

I have two very large tables to merge and so I have been trying to optomize the update for speed. I noticed that doing the update partially in PHP speeded it up significantly so I assumed this means I'm not be doing the MySQL properly. I have simplified the problem to try and narrow it down ... GRID_TABLE POSTCODE_TABLE idNo, lat, lng, nearestPostcode

为什么PHP版本比MySQL运行得更快?

我有两个非常大的表进行合并,所以我一直在尝试对速度更新进行optomize。 我注意到在PHP中部分更新加快了速度,所以我认为这意味着我没有正确地做MySQL。 我简化了这个问题,试图缩小它的范围。 GRID_TABLE POSTCODE_TABLE idNo, lat, lng, nearestPostcode postcode, lat, lng ________________________________ _____________________ 1 57.1 -2.3 -

Killing a node process after .exec() in php on mac OS

Connect PHP and Flex Player

I'm using Flex Player component on a localhost. The FLV video files are stored in bin-debug/Video Source. The PHP code for the video is: $id = $_GET["id"]; $media = getDirectoryList("bin-debug/Video Source"); if($media[$id] != null){ $video = $media[$id]; $fileName = "bin-debug/Video Source/".$video; $pieces = explode(".", $video); $video = $pieces[

我在本地主机上使用Flex Player组件。 FLV视频文件存储在bin-debug / Video Source中。 该视频的PHP代码是: $id = $_GET["id"]; $media = getDirectoryList("bin-debug/Video Source"); if($media[$id] != null){ $video = $media[$id]; $fileName = "bin-debug/Video Source/".$video; $pieces = explode(".", $video); $video = $pieces[0]; } 播放器是通过JavaScript在HT

How do I implement basic "Long Polling"?

I can find lots of information on how Long Polling works (For example, this, and this), but no simple examples of how to implement this in code. All I can find is cometd, which relies on the Dojo JS framework, and a fairly complex server system.. Basically, how would I use Apache to serve the requests, and how would I write a simple script (say, in PHP) which would "long-poll" the s

我如何实现基本的“长轮询”?

我可以找到关于长轮询如何工作的很多信息(例如,这个和这个),但没有关于如何在代码中实现的简单示例。 我只能找到cometd,它依赖于Dojo JS框架和一个相当复杂的服务器系统。 基本上,我将如何使用Apache来服务请求,以及如何编写一个简单的脚本(比如说用PHP)来“长期轮询”服务器以获取新消息? 这个例子不必是可扩展的,安全的或完整的,它只需要工作! 这比我最初想象的要简单。基本上你有一个什么都不做的页面,直

PHP interpreter Opcache

My information: PHP is a programming language which uses an interpreter. The interpreter is a compiled software between the source code and the machine. It reads and analyses the source code at runtime and starts its own Subroutines based on the source code. Its not compiling or translating the code into something new which could be saved because its a kind of executing the code. The Op

PHP解释器Opcache

我的信息: PHP是一种使用解释器的编程语言。 解释器是源代码和机器之间的编译软件。 它在运行时读取并分析源代码,并根据源代码启动其自己的子例程。 它不会将代码编译或转换为可以保存的新代码,因为它是一种执行代码的代码。 Zend的Opcache能够存储预编译的字节码并再次使用它。 (我知道它通常如何工作。) http://www.sitepoint.com/understanding-opcache/ 我的问题: Opcache在解释器未编译时从哪里获得
