大神看下这个导航菜单在smarty里怎么循环出来呢？
这是我取了其中一部分代码：
{foreach from=$nav_list name=nav_list item=nav}
| {$nav.title} |
| 机关简介 |
{if !$smarty.foreach.nav_list.last}
{/if}
{/foreach}
回复讨论(解决方案)
哪位给看下呢？谢谢了
{foreach from=$nav_list name=nav_list item=$nav}
难不成现在都没人用smarty了吗？
你现在遇到什么问题了？
你现在遇到什么问题了？
不会循环了，这是一列两行，我要循环 出图片那种效果。 你可以用你原来的程序多循环几次不就行了，
/** +---------------------------------------------------------- * 获取导航菜单 * $parent_id 默认获取一级导航 * $current_module 当前页面模型名称 * $current_id 当前页面分类ID +---------------------------------------------------------- */ function get_nav1($parent_id = 0, $current_module = '', $current_id = '', $type = 'middle') { $sql = "SELECT * FROM " . $this->table('nav') .

Lambda expression breaks out of loop
Feb 20, 2024 am 08:47 AM
Lambda expression breaks out of the loop, specific code examples are needed. In programming, the loop structure is an important syntax that is often used. However, in certain circumstances, we may want to break out of the entire loop when a certain condition is met within the loop body, rather than just terminating the current loop iteration. At this time, the characteristics of lambda expressions can help us achieve the goal of jumping out of the loop. Lambda expression is a way to declare an anonymous function, which can define simple function logic internally. It is different from an ordinary function declaration,
A comparative study of loops and recursion in Go language
Jun 01, 2023 am 09:23 AM
Note: This article compares loops and recursion from the perspective of Go language. When writing programs, you often encounter situations where a series of data or operations need to be processed repeatedly. To achieve this we need to use loops or recursion. Loops and recursions are both commonly used processing methods, but in practical applications, they each have advantages and disadvantages, so the actual situation needs to be considered when choosing which method to use. This article will conduct a comparative study of loops and recursion in the Go language. 1. Loops A loop is a mechanism that repeatedly executes a certain piece of code. There are three main types of Go language
What are the alternatives to recursive calls in Java functions?
May 05, 2024 am 10:42 AM
Replacement of recursive calls in Java functions with iteration In Java, recursion is a powerful tool used to solve various problems. However, in some cases, using iteration may be a better option because it is more efficient and less prone to stack overflows. Here are the advantages of iteration: More efficient since it does not require the creation of a new stack frame for each recursive call. Stack overflows are less likely to occur because stack space usage is limited. Iterative methods as an alternative to recursive calls: There are several methods in Java to convert recursive functions into iterative functions. 1. Use the stack Using the stack is the easiest way to convert a recursive function into an iterative function. The stack is a last-in-first-out (LIFO) data structure, similar to a function call stack. publicintfa
PHP returns all the values in the array to form an array
Mar 21, 2024 am 09:06 AM
This article will explain in detail how PHP returns all the values of an array to form an array. The editor thinks it is quite practical, so I share it with you as a reference. I hope you can gain something after reading this article. Using the array_values() function The array_values() function returns an array of all the values in an array. It does not preserve the keys of the original array. $array=["foo"=>"bar","baz"=>"qux"];$values=array_values($array);//$values will be ["bar","qux"]Using a loop can Use a loop to manually get all the values of the array and add them to a new
Java Iterator vs. Iterable: A step into writing elegant code
Feb 19, 2024 pm 02:54 PM
Iterator interface The Iterator interface is an interface used to traverse collections. It provides several methods, including hasNext(), next() and remove(). The hasNext() method returns a Boolean value indicating whether there is a next element in the collection. The next() method returns the next element in the collection and removes it from the collection. The remove() method removes the current element from the collection. The following code example demonstrates how to use the Iterator interface to iterate over a collection: Listnames=Arrays.asList("John","Mary","Bob");Iterator
Using vectorization to replace loops in python
Apr 14, 2023 pm 07:07 PM
All programming languages are inseparable from loops. So, by default, we start executing a loop whenever there is a repeating operation. But when we are dealing with large number of iterations (millions/billions of rows), using loops is a crime. You might be stuck for a few hours, only to realize later that it doesn't work. This is where implementing vectorization in python becomes very critical. What is vectorization? Vectorization is a technique for implementing (NumPy) array operations on data sets. Behind the scenes, it applies the operation to all elements of the array or series at once (unlike a "for" loop that operates one row at a time). Next we use some use cases to demonstrate what vectorization is. Find the sum of numbers##Use the loop importtimestart

How to use PHP and Smarty to achieve front-end and back-end separation development
Jun 25, 2023 pm 01:46 PM
In modern web development, the separation of front-end and back-end has become a very popular trend, which allows developers to better organize projects and improve the efficiency of project development. PHP and Smarty are two very commonly used technologies, which can be used to achieve front-end and back-end separation development. This article will introduce how to use PHP and Smarty to achieve front-end and back-end separation development. What is front-end and back-end separation development? In traditional web development, the front-end is mainly responsible for the presentation of the page and the logic of interaction with the back-end. The backend is mainly responsible for the business
