## Rewrite php script – Code Review Stack Exchange

I have written one script in PHP which is defined here:

I am improving the code quality and readability. For example splitting it into multiple functions, use PHP predefined variables, use PSR naming conventions etc.

``````class nextcrontime{
//Get Single argument passed
function calculate_next_cron(){
If(isset(\$_GET('time')) && !empty(\$_GET('time'))){
\$splitime = explode(":", \$_GET('time'));
// Loop Content from config.txt line by line and perform required actions
\$list = explode(" ", \$line);

if(\$list(0) != '*' && \$list(1)=='*'){
\$newtime = \$splitime(0).":".\$list(0);
if(strtotime(\$newtime) >=  strtotime(\$_GET('time'))){
echo \$newtime." ".'Today'." ".\$list(2);
}else{
\$time = date('Y-m-d H:i', strtotime(\$newtime) + 60*60);
if (date("Y-m-d") > \$time) {
echo date("H:i", strtotime(\$time))." ".'Today'." ".\$list(2);
}else{
echo date("H:i", strtotime(\$time))." ".'Tomorrow'." ".\$list(2);
}
}
}
}else{
echo "Please Pass Time in HH:MM format. Example > php-cgi -f Index.php time=16:10.";
return;
}
//Close File Handler
}}}

## plugin development – rewrite URL based on selected taxonomy for post page

I have a taxonomy called “group”, and their values like “red”, “blue”, “green” (these are generating dynamic” no any fixed group value.

during post publish I am selecting “Group” for each post. 1 group for each post.

I want to add a rewrite URL for the post if the taxonomy is “red” or “blue” or “green” then the URL of that post should come like

`"myweb.com/red/post-slug-name"` or `"myweb.com/green/post-slug-name"` or `"myweb.com/blue/post-slug-name"`

``````add_action( 'init', 'create_group_tax' );
function create_group_tax() {
register_taxonomy(
'group',
'post',
array( 'label' => 'Group',
'hierarchical' => true
)
);
}

``````

also, I want to make it regex rule “`'^red/((^/)*)/?'`” dynamic with selected taxonomy,this time just to make a test i added it as a static string.

what do you suggest to do this?

## functions – Hook to Rewrite Menu items titles on saving menu

Ok I have the following code in WordPress functions.php. To replace all menu title with “test”. This is working fine. But i want to have this functionality only when I save the menu on the menu admin page in the backend. I can’t seem to find the right hook to do that?

That way its called only once (and rewritten). Hope some one can point me in the right direction?

``````function update_menu_link(\$items){

foreach(\$items as \$item){

\$item->title = 'test';
}
return \$items;
}

## How to re-write this program for Python 3.7 where program will ask for the number of sides for your shape, then draw the shape?

I was trying to do an exercise where the program will ask for the number of sides for your shape, then draw the shape. I copied out the code exactly from the book, but it is outdated and was wondering how to make this work for Python 3.8?

``````import turtle
sides = int(input("Enter the number of sides for your shape: "))

angle = 360.0 / sides
length = 400.0 / sides

for side in range(sides):
turtle.forward(length)
turtle.right(angle)
turtle.done()
``````

## python 3.x – How to rewrite this program in a more easier way?

``````def alphabetlist():
print("alphabet1 = (a,b,c,d,e,f)")
print("alphabet2 = (g,h,i,j,k,l)")
print("alphabet3 = (m,n,o,p,q,r)")
print("alphabet4 = (s,t,u,v,w,x)")
print("alphabet5 = (y,z)")
print("Guess a word.")
print("Now i will try to figure out the word you guessed.")
totalletters=int(input("total number of letters in your guessed words are: "))
def chooselist(x):
if x == 1:
print(alphabet1)
elif x == 2:
print(alphabet2)
elif x == 3:
print(alphabet3)
elif x == 4:
print(alphabet4)
elif x == 5:
print(alphabet5)
list=( )
def listtranspose(w):
if w == 1:
i=int(input());list.append(alphabet1(i-1))
elif w == 2:
i=int(input());list.append(alphabet2(i-1))
elif w == 3:
i=int(input());list.append(alphabet3(i-1))
elif w == 4:
i=int(input());list.append(alphabet4(i-1))
elif w == 5:
i=int(input());list.append(alphabet5(i-1))
alphabetlist()
alphabet1 = ("a","b","c","d","e","f")
alphabet2 = ("g","h","i","j","k","l")
alphabet3 = ("m","n","o","p","q","r")
alphabet4 = ("s","t","u","v","w","x")
alphabet5 = ("y","z")
step_1=( );h=0
while totalletters>h:
print("your letter is from which list 1,2,3,4,5")
x = int(input())
step_1.append(x);h+=1
print("***n  1    2    3    4    5    6   ")
g=0
while totalletters>g:
chooselist(step_1(g));g+=1
print("*******");e=0
while totalletters>e:
print("choose from these lists again now 1,2,3,4,5,6")
listtranspose(step_1(e));e+=1
print("the word you guessed is: ",end=" ")
for i in range(0,len(list),1):
print(list(i),end="")
``````

This program is a word guessing game. The user thinks of a word and this program guesses it. through a series of list I want to know if there are other ways to write this, more easily actually I get all the functions used but not the next part

## apache 2.2 – Rewrite userdir for users that changed the username

This seems simple, but I wasn’t able to do it.

I have a user that changed his username from `givenname` to `name`, and now I need to rewrite, changing the URL on the clients, to avoid 404 errors on ~givenname.

I thought I could do something like this:

``````RewriteBase /~givenname/
RewriteRule ^givenname\$ name\$ (R)
``````

But I was unable to do this.

I’m aware that `mod_userdir` looks for specific user info on Unix files (`/etc/passwd`) or whatever is specified on `/etc/nsswitch.conf`, but there’s a way to trick it and redirect to the new username?

Thanks.

PS: I’m running a little old Apache 2.2.16 server.

## permalinks – Default Post post type and custom post type rewrite slugs

So, currently, my blog page is at /blog/ and I also have 2 custom post types. What I’m trying to get is to have all the posts/archives of the Post post type show under /blog/, and for one of the custom post type to use “/” as a rewrite slug. That way, I could get mysite.com/service-foo, mysite.com/bar-service, which are the custom post types, and if I go to post archive for December of 2020, it would show under /blog/2020/12/.

I’ve tried that, as I said, by setting `/blog/%postname%/` under my wp admin permalink settings, and using `'rewrite' => array( 'slug' => '/', 'with_front' => false ),` with register_post_type for my custom post type. That works for blog posts, but my custom post type posts show 404, with proper url though.

## integration – How to rewrite this normal derivative in a sphere as a radial derivative?

I’ve come across the following line of working in a set of notes on the mean value theorem for harmonic functions:
$$int_{partial B_r(x)} frac{partial u}{partial nu}, dS = r^{n-1} int_{partial B_1(0)} frac{partial u}{partial r}(x+ry) , dS(y)$$
What I don’t understand is how the two derivatives are converted into one another. The $$r^{n-1}$$ seems to come from the Jacobian determinant $$(=r^n)$$ and the factor of $$frac{1}{r}$$ which appears in the normal vector to the ball of radius $$r$$. I think this should leave you with an integrand of $$nabla u cdot (x+ry)$$ but I’m not sure how this is equivalent to the integrand in the expression above. Any help is greatly appreciated.

## Nginx proxy_pass rewrite URL and Headers

Solved, the problem is regex only match `path` or

``````/httpbin.org/anything
``````

not parameter or query string

``````?test=data@cookieValue
``````

to solve the problem I change the URL to

``````http://localhost/app/cookieValue/httpbin.org/anything?test=data
``````

and here the config

``````location ~ ^/app/((^/)+)/(.*){
resolver 8.8.8.8;
proxy_pass https://\$2\$is_args\$args;
