Scenario for a man's birthday. Multi-level menu in PHP and MySQL Dance at the command of the leader


Can be used with the parameter " ?search_string=search_query". Otherwise it will try to get it from the URL.

%total%

Displays the total number of news items in the feed. Can be used for the %system numpages()% macro.

%per_page%

Displays the value of the per_page parameter. Can be used for the %system numpages()% macro.

%list-class-first%

if the element is the first, outputs "first"

%list-class-last%

if the element is the last, outputs "last"

%list-class-odd%

if the element is even, prints "odd"

%list-class-even%

if the element is odd, prints "even"

%list-position%

inserts a serial number in the list

search_empty_result

Used if no pages were found as a result of the search. In this case, this block is output instead of the search_block block.

%last_search_string%

Displays the previous search query, if there was one.

search_block_line_quant

Outputs a separator that is inserted between search results.

Examples of use Title

%search search_do()% — Displays search results for the site.

Parameters: search search_do()

template

The name of the template by which site search results should be displayed. Ignored in the XSLT template engine.

Search_string

Search phrase. If the value is not specified, it is taken from the request sent through the search form.

Search_types

List of hierarchical type identifiers for search (specified separated by a space). If the value is not specified, the search is carried out across all types.

Search_branches

List of sections in which the search will be carried out (indicated by a space). If the value is not specified, the search is carried out across all sections. The parameter can accept both page ids and their URLs.

Per_page

Number of results per page. If the parameter is not specified, the value specified in the settings of the "Search" module will be taken.

Description

Displays search results if they are submitted via a form rendered using the %search insert_form()% macro (the search query will be present in the URL after the form data is submitted).

By default, the system page with the address is used to display search results /search/search_do/. You can create a regular content page and insert a macro into it %search search_do(...)% and in the search form displayed via %search insert_form()% change the action attribute of the form tag to the address of this content page.

In the search results, the searched words will be highlighted with a tag.

In this article I will show how you can create a multi-level menu in PHP and MySQL. Of course, you can come up with many options for creating it, but judging by the number of your questions on this topic, you need an example. And I will give it in this article. I would like to note right away that this article makes sense only for those who know PHP and know how to work with MySQL. Everyone else needs to go through this first, or read some books on PHP and MySQL.

First, let's create a table in the database with the following fields:

  • id - unique identifier.
  • title - anchor link in the menu.
  • link - the address to which the menu item will lead.
  • parent_id - parent ID. If there is no parent item, then it will be NULL (or you can also put 0).

We've sorted out the table, now it's time for the PHP code. The complete PHP code is below:



Menu




This code is completely working, however, you should understand that no one writes this way (in particular, output via echo HTML tags). And your task is to take the algorithm from this code, but not the code itself. And then connect this algorithm to your engine. I tried to carefully comment on the code for displaying a multi-level menu in PHP and MySQL, but, of course, it is not the most transparent and requires quite a bit of basic knowledge. If you still don’t know PHP and MySQL well, then I strongly recommend going through this one first.

I"m going to show you how to create simple search using PHP and MySQL. You"ll learn:

  • How to use GET and POST methods
  • Connect to database
  • Communicate with database
  • Find matching database entries with word given or phrase
  • Display results
Preparation

You should have Apache, MySQL and PHP installed and running of course (you can use for different platforms or WAMP for windows, MAMP for mac) or a web server/hosting that supports PHP and MySQL databases.

Let's create database, table and fill it with some entries we can use for search:

  • Go to phpMyAdmin, if you have server on your computer you can access it at http://localhost/phpmyadmin/
  • Create database, I called mine tutorial_search
  • Create table I used 3 fields, I called mine articles.
  • Configuration for 1st field. Name: id, type: INT, check AUTO_INCREMENT, index: primary

INT means it"s integer
AUTO_INCREMENT means that new entries will have other(higher) number than previous
Index: primary means that it"s unique key used to identify row

  • 2nd field: Name: title, type: VARCHAR, length: 225

VARCHAR means it string of text, maximum 225 characters(it is required to specify maximum length), use it for titles, names, addresses
length means it can"t be longer than 225 characters(you can set it to lower number if you want)

  • 3rd field: Name: text, type: TEXT

TEXT means it"s long string, it"s not necessary to specify length, use it for long text.

  • Fill the table with some random articles(you can find them on news websites, for example: CNN, BBC, etc.). Click insert on the top menu and copy text to a specific fields. Leave "id" field empty. Insert at least three.

It should look something like this:

  • Create a folder in your server directory and two files: index.php and search.php (actually we can do all this just with one file, but let"s use two, it will be easier)
  • Fill them with default html markup, doctype, head, etc.

Search

  • Create a form with search field and submit button in index.php, you can use GET or POST method, set action to search.php. I used "query" as name for text field

GET - means your information will be stored in url (http://localhost/tutorial_search/search.php?query=yourQuery)
POST - means your information won"t be displayed it is used for passwords, private information, much more secure than GET

Ok, let's get started with php.

  • Open search.php
  • Start php()
  • Connect to a database(read comments in following code)
