I have scripts for importing categories and products from XML to Opencart.
This script was written for Opencart 2.1.0.2 and now I want to use this script for version 1.5.6.1.
After run this script It wrote me error - "Failed loading XML:"
And thats all.
Is something different in code for older version of Opencart?
Thanks.
Here is example of script for importing categories:
<?php
// Version
define('VERSION', '1.5.6.1');
// Configuration
if (is_file('config.php')) {
require_once('config.php');
}
// Install
if (!defined('DIR_APPLICATION')) {
header('Location: install/index.php');
exit;
}
// Startup
require_once(DIR_SYSTEM . 'startup.php');
// Registry
$registry = new Registry();
// Loader
$loader = new Loader($registry);
$registry->set('load', $loader);
// Config
$config = new Config();
$registry->set('config', $config);

$db = new DB(DB_DRIVER, DB_HOSTNAME, DB_USERNAME, DB_PASSWORD, DB_DATABASE, DB_PORT);
$registry->set('db', $db);

I have a program for converting full width characters to half width. It works fine, except for the number zero. Full-width zero is not converting to half-width zero.
Perl
use strict;
use warnings;
use warnings qw(FATAL utf8);
use utf8;
use feature qw(unicode_strings);
use open qw(:std :utf8);
unless ( #ARGV == 2 ) {
print "Usage: script.pl input_file output_file\n";
exit;
}
my %fwhw = (
'０' => '0', '１' => '1', '２' => '2', '３' => '3', '４' => '4',
'５' => '5', '６' => '6', '７' => '7', '８' => '8', '９' => '9',
'Ａ' => 'A', 'Ｂ' => 'B', 'Ｃ' => 'C', 'Ｄ' => 'D', 'Ｅ' => 'E',
'Ｆ' => 'F', 'Ｇ' => 'G', 'Ｈ' => 'H', 'Ｉ' => 'I', 'Ｊ' => 'J',
'Ｋ' => 'K', 'Ｌ' => 'L', 'Ｍ' => 'M', 'Ｎ' => 'N', 'Ｏ' => 'O',
'Ｐ' => 'P', 'Ｑ' => 'Q', 'Ｒ' => 'R', 'Ｓ' => 'S', 'Ｔ' => 'T',
'Ｕ' => 'U', 'Ｖ' => 'V', 'Ｗ' => 'W', 'Ｘ' => 'X', 'Ｙ' => 'Y',
'Ｚ' => 'Z', 'ａ' => 'a', 'ｂ' => 'b', 'ｃ' => 'c', 'ｄ' => 'd',

'ｙ' => 'y', 'ｚ' => 'z', '－' => '-', '、' => ', ', ' ' => ' ',
'／' => '/',);
sub slurp {
my $file = shift;
open my $fh_read, '<', $file or die "Could not open file: $!";
return do {local $/; <$fh_read>};
}
sub convert {
my $sub_string = shift;
$sub_string =~ s/(.)/$fwhw{$1}?$fwhw{$1}:$1/seg;
return $sub_string;
}
my $string = slurp($ARGV[0]);
$string =~ s/<target>\s*<g id="\d+">\K(.*?)(?=<\/g>\s*<\/target>)/convert($1)/seg;
open my $fh_write, ">", $ARGV[1] or die "Could not open file: $!";
print $fh_write $string;
close $fh_write;
Here is what I have tried
I have made sure that the number 0 (zero) and the letter O (oh) are indeed different by checking their code points. Full width 0 is \x{ff10}. Full width letter O is \x{ff2f}. I checked this using this code:
use Encode;
sub codepoint_hex {
sprintf "%04x", ord Encode::decode("UTF-8", shift);
}
my $codepoint = codepoint_hex('０');
print $codepoint, "\n";
I have checked that the hash is indeed loading all of the keys and values correctly.
What I haven't tried yet:
I haven't tried to duplicate this oddity on Linux yet. I am using ActiveState Perl 5.24 on Windows 10.
If anyone has any suggestions or sees my mistake, I would be very grateful for the guidance.
Since $fwhw{'０'} returns 0, and since 0 is false, the replacement doesn't occur. Replace
$sub_string =~ s/(.)/$fwhw{$1}?$fwhw{$1}:$1/seg;
with
$sub_string =~ s/(.)/exists($fwhw{$1})?$fwhw{$1}:$1/seg;
If that still doesn't work, use sprintf "%vX", $str to see what you really have.
By the way,
sub convert {
my $sub_string = shift;
$sub_string =~ s/(.)/exists($fwhw{$1})?$fwhw{$1}:$1/seg;
return $sub_string;
}
would be much faster if replaced with
sub convert {
state $chars = join '', keys(%fwhw);
state $re = qr/([\Q$chars\E])/;
return $_[0] =~ s/$re/$fwhw{$1}/gr;
}
Faster yet,
sub convert {
state $s = join '', keys(%fwhw);
state $r = join '', values(%fwhw);
state $tr = eval("sub { $_[0] =~ tr/\Q$s\E/\Q$r\E/r }");
return $tr->($_[0]);
}
You don't need such a huge dictionary with lots of supporting functions like that. Just a simple sed is enough
halfwidth='!"#$%&'\''()*+,-.\/0123456789:;<=>?#ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz{|}~｟｠¢£¬¯¦¥₩ '
fullwidth='！＂＃＄％＆＇（）＊＋，－．／０１２３４５６７８９：；＜＝＞？＠ＡＢＣＤＥＦＧＨＩＪＫＬＭＮＯＰＱＲＳＴＵＶＷＸＹＺ［＼］＾＿｀ａｂｃｄｅｆｇｈｉｊｋｌｍｎｏｐｑｒｓｔｕｖｗｘｙｚ｛｜｝～｟｠￠￡￢￣￤￥￦ '
sed -ie "y/$fullwidth/$halfwidth/" your_file
If you want to do that in perl it's pretty simple too
perl -Mutf8 -i -C -pe 'BEGIN{ use open qw/:std :utf8/; } tr#！＂＃＄％＆＇（）＊＋，－．／０１２３４５６７８９：；＜＝＞？＠ＡＢＣＤＥＦＧＨＩＪＫＬＭＮＯＰＱＲＳＴＵＶＷＸＹＺ［＼］＾＿｀ａｂｃｄｅｆｇｈｉｊｋｌｍｎｏｐｑｒｓｔｕｖｗｘｙｚ｛｜｝～｟｠￠￡￢￣￤￥￦ #!"\#$%&'\''()*+,-.\/0123456789:;<=>?#ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz{|}~｟｠¢£¬¯¦¥₩ # your_file'
I am having a problem trying to assing a single value to a list within a list
example:
create a list with 11 lists of 11 strings
board=[['.'](10+1)](10+1)
board
[['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.']]
assign value 'O' to the first string of the first list
board[0][0]='O'
I am getting to following output
board
[['O', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['O', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['O', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['O', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['O', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['O', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['O', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['O', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['O', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['O', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['O', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.']]
Instead I was expected to have this other output that i am not getting:
[['O', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.'], ['.', '.', '.', '.', '.', '.', '.', '.', '.', '.', '.']]
That's it. I expected to get string 'O' only for the first element of the first listv in board!
I don't understand why i am getting value 'O' to the first value in every single list when I only selected the first one.
Thank you for any comment to all!
In your code, this line:
>>> board = [['.']*(10+1)]*(10+1)
appears to create a 2D grid with independent rows of cells however it doesn't quite do that, and this is a common issue experienced with creating n-dimensional lists in Python.
What this code does is create one row and then the board is a list where each item in the list references the same row.
You can see that by using id():
>>> id(board[0])
4497981128
>>> id(board[1])
4497981128
>>> id(board[2])
4497981128
>>> id(board[0]) == id(board[1]) == id(board[2])
True
All three memory addresses are the same, so changing an element at index i in one, changes it in all of them.
What you want to do is generate each row separately:
>>> board = [['.']*(10+1) for _ in range(10+1)]
(The _ is a convention for a needed but unused variable.)
This way each row is a separate object in memory:
>>> id(board[0]) == id(board[1]) == id(board[2])
False
>>> id(board[0])
4497941384
>>> id(board[1])
4497989256
>>> id(board[2])
4497919688
You can try this:
board = [["." for i in range(11)] for b in range(11)]
board[0][0] = "O"
That will give you the single "O" at the 0th index of the first list.

Hi,
I'm trying to create some code that will load this maze layout from a .txt file and put it into a 2d array. Currently it just puts the maze layout straight into the 2d array without having it stored in a .txt file.
Does anyone know how I will do this?
Step 1: Create a text file which looks like:
XXXXXXXXXXXXXXXXXXXX
X###################
X##### ###########
X##### ###########
X##### ###########
X### ##########
X### # ## ##########
X# # ## ##### ++#
X# ++#
X##### ### # ## ++#
X##### #########
X###################
Step 2: write the code for reading the maze text file
char initialMaze[SIZEY+1][SIZEX+1];
int row = 0;
ifstream fstrm("filename.txt");
while(fstrm.getline(initialMaze[row], SIZEX+1)) {
++row;
}
If the text representing the maze is in a text file called maze.txt,
Then the following code might be sufficient,
char initialMaze[SIZEY+1][ SIZEX+1];
string temp;
int i=0;
ifstream var("maze.txt");
if (myfile.is_open())
{
while(getline(var,temp) )
{
strcpy(initialMaze[i],temp.c_str());
i++;
}
myfile.close();
}
maze.txt:
XXXXXXXXXXXXXXXXXXXX
X###################
X##### ###########
X##### ###########
X##### ###########
X### ##########
X### # ## ##########
X# # ## ##### ++#
X# ++#
X##### ### # ## ++#
X##### #########
X###################
maze.cpp:
#include <fstream>
#include <string>
#include <vector>
#include <cstdlib>
int main() {
std::ifstream fin("maze.txt");
if (!fin) return EXIT_FAILURE;
std::vector<std::string> maze;
std::string line;
while (std::getline(fin, line)) {
maze.push_back(line);
}
}
This gets the data into maze, where you can access any cell using maze[row][column]. The maze can be practically any size, and rows don't even have to all be the same length. (Just be sure when you access an element that the row and column are inside the maze:
if (0 <= row && row < maze.size() && 0 <= column && column < maze[row].size()) {
maze[row][column] ...
}

I have the following code and want to see if the string 'userFirstName' contains any of the characters in the char array. If the string does I want it to ask the user to reenter their first name and then check the new name for invalid characters and so on.
char invalidCharacter[] = { '!', '#', '#', '$', '%', '^', '&', '*', '(', ')', '~', '`',
';', ':', '+', '=', '-', '_', '*', '/', '.', '<', '>', '?', ',', '[', ']', '{', '}',
'0', '1', '2', '3', '4', '5', '6', '7', '8', '9' };
cout << "Please enter your first name: " << endl;
cin >> userFirstName;`
Use string::find_first_of to do it.
Assuming that userFirstName is a string:
size_t pos = userFirstName.find_first_of(invalidChars, 0, sizeof(invalidChars));
if (pos != string::npos) {
// username contains an invalid character at index pos
}
