Laravel E-com delivery charges by calculate between kilometer

may I know is it possible the shipping fees is calculated by kilometer within a distance from my coordinate location?
For example, i already set a coordinate location that would be my physical store, and my shipping area only can deliver within 20 kilometer from my location.
How am i suppose to let customer can only choose the shipping area within 20 km from my location, and set a shipping fees on it?
Please help. Much appreciated and thank you all.

If you only need rough numbers and don't care if it's 20 or 23 km then you can use post codes.
If you want to you can "fine tune" each post code with street, and if needed with house number.
$UserPostCode = 12345;
$UserStreet = "3-street";
$Postcodes = [
"11111" => [
"A-street" => 12,
"B-street" => 10,
"C-street" => 15,
"Default" => 11
],
"12345" => [
"1-street" => 5,
"2-street" => 6,
"3-street" => 7,
"Default" => 5
]
];
if(isset($PostCodes[$UserPostCode])){
// post code is within your range
if(isset($PostCodes[$UserPostCode][$UserStreet])){
// you have a price set for this street
echo $PostCodes[$UserPostCode][$UserStreet]; //7
}else{
// This is a new street in the postcode unknown to you, give default price
echo $PostCodes[$UserPostCode]["Default"];
}
}else{
// customer lives out of range
echo "Sorry can't deliver to you";
}
As I wrote above you can fine tune the streets to house number 1-50 and 50 and higher if you like with the same logic as above.

Delivery charge for if postcode starts with ?? Javascript or PHP

I have a list of postcodes in the UK with a region id next to it. Now for delivering products it costs more depending on the region a user lives in.
For example, if a user lives in Birmingham and has a postcode that starts with B, he will get free delivery because that postcode region doesn't have any charge.
Likewise, if a user has a postcode starting with IM , they have to pay more delivery as that postcode region is more.
Sample postcode list:
Postcode | Region
AL | A
BA | A
BB | A
BD | A
B | B
BH | B
LN | D
LS | D
IV1 | E
IV23 | F
From the example above if a user wants to get a delivery and their postcode starts with BA then I want to apply the delivery charge rate of region A.
I'm actually a bit confused as to how I can programmatically do this. At first I thought I would simply do something similar to:
$postcodes = [
'AL'=>'A',
'BA'=>'A',
//And so on ....
];
//get the first 2 letters
$user_input = substr( $user_postcode, 0, 2 );
if(array_key_exists($user_input,$postcodes)){
//Get the region code
$region = $postcodes[$user_input];
// Charge the user with the delivery rate specific to that user, then carry on
}
But problem is that some similar postcodes can be in different regions, so for example, IV1 is region E and IV23 is region F like seen above.
That means I have to match a users post code on either, the 1 , 2 ,3 or 4 characters. That probably doesn't make sense. To elaborate more see below:
//From Birmingham and is in region B
$user1_input = 'B';
//From Bradford and is in region A
$user1_input = 'BD';
//From Inverness and is in region E
$user1_input = 'IV1';
So if the user input is from Birmingham and user input starts with B , how can i tell that apart from a postcode that also starts with B but then has other letters in it which makes it a different postcode.
I'm trying my best to explain, hopefully, this does make sense. If not please ask for more info.
Can anyone please help me with the logic to how I could achieve this? Either in Javascript or PHP , because i can convert the logic afterwards.

If you have what looks like a valid UK postcode, then remove the spaces and just search the array till you find a match:
$lookup = [
'' => 'X', // in case no match is found
'AL'=>'A',
'BA'=>'A',
//And so on ....
];
function get_delivery_for($postcode)
{
global $lookup;
for ($x=5; $x>0 && !$result; $x--) {
$result=$lookup[substr($postcode, 0, $x)];
}
return ($result);
}
Note that the code above is intended for illustration, I would recommend using something more elaborate to avoid it throwing warnings....
$result=isset($lookup[substr($postcode, 0, $x)])
? $lookup[substr($postcode, 0, $x)]
: false;

One option would be to order your postcode/region array by the descending length of the postcode key. This way, the longer (more specific) keys are checked first. Taking your list above, it would become something like this...
$postcodes = array(
"IV23" => "F",
"IV1" => "E",
"LS" => "D",
"LN" => "D",
"BH" => "B",
"BD" => "A",
"BB" => "A",
"BA" => "A",
"AL" => "A",
"B" => "B",
);
After you have that, it's as simple as looping through the array, checking for a match against the provided postcode (starting from the left), and stopping when you find a match.
foreach($postcodes as $code => $region)
{
if($code == substr($user_postcode, 0, strlen($code)))
{
$shippingRegion = $region;
break;
}
}
echo $shippingRegion;

Javascript regex with varying input

I want to filter out the following information out of a long piece of text. Which I copy
and paste in a textfield and then want to process into a table as a result. with
Name
Address
Status
Example snippet:(Kind of randomized the names and addresses etc)

My strategy for the moment is using the following:
Filter all the lines with at least two words in capitals at the beginning of the line. AND a 4 digit postal code.
Then discard all the other lines as I only need the lines with the names and adresses
Then I strip out all the information needed for that line
Strip the name / address / status
I use the following code:
//Regular expressions
//Filter all lines which start with at least two UPPERCASE words following a space
pattern = /^(([A-Z'.* ]{2,} ){2,}[A-Z]{1,})(?=.*BSN)/;
postcode = /\d{4}/;
searchSober= /(N - Sober)+/;
searchNotSober= /(NN - Not sober)+/;
adres = inputText.split('\n');
for (var i = 0; i < adres.length; i++) {
// If in one line And a postcode and which starts with at least
// two UPPERCASE words following a space
temp = adres[i]
if ( pattern.test(temp) && postcode.test(temp)) {
//Remove BSN in order to be able to use digits to sort out the postal code
temp = temp.replace( /BSN.*/g, "");
// Example: DUMMY FOO V Stationstreet 2 8000 New York F N - Sober
//Selection of the name, always take first part of the array
// DUMMY FOO
var name = temp.match(/^([-A-Z'*.]{2,} ){1,}[-A-Z.]{2,}/)[0];
//remove the name from the string
temp = temp.replace(/^([-A-Z'*.]{2,} ){1,}[-A-Z.]{2,}/, "");
// V Stationstreet 2 8000 New York F N - Sober
//filter out gender
//Using jquery trim for whitespace trimming
// V
var gender = $.trim(temp.match(/^( [A-Z'*.]{1} )/)[0]);
//remove gender
temp = temp.replace(/^( [A-Z'*.]{1} )/, "");
// Stationstreet 2 8000 New York F N - Sober
//looking for status
var status = "unknown";
if ( searchNotsober.test(temp) ) {
status = "Not soberr";
}
else if ( searchSober.test(temp) ) {
status = "Sober";
}
else {
status = "unknown";
}
//Selection of the address /^.*[0-9]{4}.[\w-]{2,40}/
//Stationstreet 2 8000 New York
var address = $.trim(temp.match(/^.*[0-9]{4}.[\w-]{2,40}/gm));
//assemble into person object.
var person={name: name + "", address: address + "", gender: gender +"", status:status + "", location:[] , marker:[]};
result.push(person);
}
}
The problem I have now is that:
Sometimes the names are not written in CAPITALS
Sometimes the postal code is not added so my code just stops working.
Sometimes they put a * in front of the name
A broader question is what strategy can you take to tackle these type of messy input problems?
Should I make cases for every mistake I see in these snippets I get? I feel like
I don't really know exactly what I will get out of this piece of code every time I run
it with different input.

Here is a general way of handling it:
Find all lines that are most likely matches. Match on "Sober" or whatever makes it unlikely to miss a match, even if it gives you false positives.
Filter out false positives, this you have to update and tweak as you go. Make sure you only filter out what isn't relevant at all.
Strict filtering of input, what doesn't match gets logged/reported for manual handling, what does match now conforms to a known strict pattern
Normalize and extract data should now be much easier since you have limited possible input at this stage

javascript regex to get characters between the ":"'s from "Retail Sales of Electricity : Colorado : Commercial : Annual"

Ideally, I'd like to skip the spaces on either side.
I've gotten as far as (: \S*), which obviously isn't really what I want.
getting the text between as groups would be great.

var str = "Retail Sales of Electricity : Colorado : Commercial : Annual";
str.match(/\b[^:]+\b/g);

You can try with:
var input = "Retail Sales of Electricity : Colorado : Commercial : Annual";
var output = input.split(':').map(function(s){ return s.trim(); });

Your help would be greatly appreciated.
Thank You,

use:
var Jsonstring = {title: "Movie", actors: [ 'actor1','actor2']};
var movie = $.parseJSON(Jsonstring);
alert(movie.title); //will alert Movie
alert(movie.actors[0]) // will alert actor1
this function will convert your json string to javascript object.

You can parse it with RegExp:
var str = obj.query.pages[564947].revisions[0]['*'],
matches = str.match(/\|\s+(starring)\s+=\s+(.+)\n/),
result = matches[1] + ': ' + matches[2].replace(/<br\s+\/>/ig, ', ').replace(/[\[\]]/ig, '');
There will be starring: Will Smith, Bridget Moynahan, Bruce Greenwood, James Cromwell, Chi McBride, Alan Tudyk in the result variable.
