PHP - Bbcode Parser Problem

I was wonder how I could make some BBcode for my messaging system I made for a website. I made some simple ones like just by replace [ red ] with font color etc. I want to know how to do something like this:

[ url = http://google . ca] Google [ / url ] without the spaces.

Ok, so i'm working on my forum software in PHP to both get some knowledge out of this and accomplish something in the run. While adding a BBCode parser, I ran into some trouble.

This is what happened:

As you can see, a <br /> tag shows up after EVERY line...
Here is my BBCode parser:

Hi there,

This isn't really a bbcode parser problem, but it kind of is. And I am awful at explaining things, as you have noticed.

The problem is that I'd like to allow input for the main page of a site. But the part has this structu
Code: [Select]
<div class='mainheader'>TITLE</div>
<div class='content'> The content of the webpage blabla</div>
I'd like this whole page to be changeable, so also the title and the content. But how can I ensure that people use the content div after the mainheader div?
I would like it if it were possible that they only needed to 'select' the header, how can I do this?

Thanks in advance!

hello dear Freaks 

 

i am currently  musing bout the portover of a python bs4 parser to php -  working with the simplehtmldom-parser / pr the DOM-selectors... (see below).

The project: for a list of meta-data of wordpress-plugins: - approx 50 plugins are of interest! but the challenge is: i want to fetch meta-data of all the existing plugins. What i subsequently want to filter out after the fetch is - those plugins that have the newest timestamp - that are updated (most) recently. It is all aobut acutality...

https://wordpress.org/plugins/participants-database ....and so on and so forth.  

https://wordpress.org/plugins/wp-job-manager
https://wordpress.org/plugins/ninja-forms
https://wordpress.org/plugins/participants-database ....and so on and so forth.
 

we have the following set of meta-data for each wordpress-plugin:

Version: 1.9.5.12 
installations: 10,000+    
WordPress Version: 5.0 or higher 
Tested up to: 5.4 PHP  
Version: 5.6 or higher    
Tags 3 Tags:databasemembersign-up formvolunteer
Last updated: 19 hours ago

 

the project consits of two parts:   the looping-part: (which seems to be pretty straightforward). the parser-part: where i have some issues - see below. I'm trying to loop through an array of URLs and scrape the data below from a list of wordpress-plugins. See my loop below-

as a base i think it is good starting point to work from the following target-url: 

 plugins wordpress.org/plugins/browse/popular with 99 pages of content: cf ...
 wordpress.org/plugins/browse/popular/page/1 
wordpress.org/plugins/browse/popular/page/2
wordpress.org/plugins/browse/popular/page/99

 

the Output of text_nodes:

['Version: 1.9.5.12', 'Active installations: 10,000+', 'Tested up to: 5.6 ']  

but if we want to fetch the data of all the wordpress-plugins and subesquently sort them to show the -let us say - latest 50 updated plugins. This would be a interesting task:

 

first of all we need to fetch the urls

then we fetch the information and have to sort out the newest- the newest timestamp. Ie the plugin that updated most recently

List the 50 newest items - that are the 50 plugins that are updated recently ..

 

we have the following set
 

see here the Soup_ 

 soup = BeautifulSoup(r.content, 'html.parser')
        target = [item.get_text(strip=True, separator=" ") for item in soup.find(
            "h3", class_="screen-reader-text").find_next("ul").findAll("li")[:8]]
        head = [soup.find("h1", class_="plugin-title").text]
        new = [x for x in target if x.startswith(
            ("V", "Las", "Ac", "W", "T", "P"))]
        return head + new


with ThreadPoolExecutor(max_workers=50) as executor1:
    futures1 = [executor1.submit(parser, url) for url in allin]

for future in futures1:
    print(future.result())

 

see the formal output

Well - i guess that we c an do this with the simple DOM Parser - here the seclector reference.

look forward to any hint and help.
