Add multiple languages to ecshop

Requirement: the foreground uses English (en_us) by default. You can select Chinese (zh_cn), and the English page is still in English. Idea: Add lang to the accessed url],

Requirement: the foreground uses English (en_us) by default. You can select Chinese (zh_cn), and the English page is still in English. Idea: add the lang = zh_cn variable to the accessed url to use Chinese characters. If there is no lang variable, use the default language scheme: When the url does not have the lang variable, if the logged-on user sets $ _ SESSION ['lang '],

Requirements:
By default, the foreground uses English (en_us). You can select Chinese (zh_cn), and the English page is still in English.

Ideas:
Add the lang = zh_cn variable to the accessed url to use Chinese characters. If there is no lang variable, use the default language.

Solution:
When the url does not have the lang variable, if the logged-on user sets $ _ SESSION ['lang '], use $ _ SESSION ['lang'] as the default language, if $ _ COOKIE ['lang '] is set for a user who has not logged on, $ _ COOKIE ['lang'] is used as the default language; otherwise, 'en _ us' is used as the default language.

Implementation:
0. Input lang = zh_cn or lang = en_us into the url to load the Language Pack.
Open mongodes/init. php and add the following code after code $ _ CFG = load_config:

$ _ CFG ['lang '] = 'en _ us'; // The foreground uses English by default $ langList = array ('zh _ cn', 'en _ us '); // The language that can be used if (! Empty ($ _ REQUEST ['lang ']) & in_array ($ _ REQUEST ['lang'], $ langList )) {$ _ CFG ['lang '] = $ _ REQUEST ['lang']; // language parameter passed through URL}

Then
If (DEBUG_MODE & 1) = 1)
Previously added:

// If you customize the default language, reload the language if (empty ($ _ REQUEST ['lang ']) |! In_array ($ _ REQUEST ['lang '], $ langList) {if (! Empty ($ _ SESSION ['lang ']) & in_array ($ _ SESSION ['lang'], $ langList) & $ _ SESSION ['lang ']! = $ _ CFG ['lang ']) {$ _ CFG ['lang'] = $ _ SESSION ['lang ']; require (ROOT_PATH. 'AGES /'. $ _ CFG ['lang ']. '/common. php '); $ smarty-> assign ('lang', $ _ lang);} else if (! Empty ($ _ COOKIE ['lang ']) & in_array ($ _ COOKIE ['lang'], $ langList) & $ _ COOKIE ['lang ']! = $ _ CFG ['lang ']) {$ _ CFG ['lang'] = $ _ COOKIE ['lang ']; require (ROOT_PATH. 'AGES /'. $ _ CFG ['lang ']. '/common. php '); $ smarty-> assign ('lang', $ _ lang );}}

1. Implement the function of adding a language identifier after the url

/*** Add the language ID to the url */function url_lang ($ url) {if (! Empty ($ _ GET ['lang ']) & $ url [0]! = '#'&&! Preg_match ("/[&?] Lang = (.*?) /", $ Url) {$ anchor = strstr ($ url, '#'); // The anchor must be placed after the request variable if ($ anchor) {$ url = str_replace ($ anchor, '', $ url ); // remove the anchor} // The request variable already exists in the url, and add "& lang = $ _ GET ['lang ']". Otherwise, add "? Lang = $ _ GET ['lang '] "$ url. = (strpos ($ url ,'? ')! = False? '&':'? '). 'Lang ='. $ _ GET ['lang ']; $ url. = $ anchor; // Add an anchor} return $ url ;}

2. Modify the build_uri () function
// Add the following before return $ uri:
$ Uri = url_lang ($ uri );

3. Add the variable in the template, such as {$ var}, to {$ var | url} so that the program can automatically identify whether lang = zh_cn | en_us needs to be added.
Add a case before default: Of the cls_template: get_val () function. The Code is as follows:

case 'url' :    $p = 'url_lang(' . $p . ', 1)';    break;

4. Add the on-site link in the template to identify whether lang = zh_cn | en_us needs to be added (The on-site link does not need to be added)
4.1 Change {$ xxx} to {$ xxx | url} using a single variable as the url in the template}
4.2 If the template uses multiple variables as URLs without other strings, change the first variable to {$ xxx | url}
4.3 In the template, the variable mixed string is used as the url and added at the end of the url as needed
{If $ smarty. get. lang} & lang = {$ smarty. get. lang} {/if} or {if $ smarty. get. lang }? Lang = {$ smarty. get. lang} {/if}

5. Modify the jump url in the foreground program

------------

Solution 2: If you only need one page setting language and other pages change at the same time, we can use cookies to accommodate a large number of days.
1. Set Language
Add lang = xxx & set_lang = 1 to the url of the language to be set.

2. Use different languages

/* Load the system parameter */$ _ CFG = load_config (); // simon: select the language $ _ CFG ['lang '] = 'en _ us '; // The front-end uses English by default. // the Hong Kong, Macao, and Taiwan browsers use traditional Chinese if (preg_match ("/(zh \-tw) by default. | (zh \-hk) | (zh \-mo) | (zh \-hant)/I ", $ _ SERVER ['HTTP _ ACCEPT_LANGUAGE ']) {$ _ CFG ['lang '] = 'zh _ tw ';} // elseif (preg_match ("/(zh \-cn) | (zh \-sg) | (zh \-hans) /I ", $ _ SERVER ['HTTP _ ACCEPT_LANGUAGE ']) {$ _ CFG ['lang'] = 'zh _ cn';} if (! Empty ($ _ REQUEST ['lang ']) |! Empty ($ _ COOKIE ['lang ']) {$ lang = empty ($ _ REQUEST ['lang'])? $ _ COOKIE ['lang ']: $ _ REQUEST ['lang']; if (in_array ($ lang, array ('zh _ cn', 'zh _ tw ', 'en _ use') {$ _ CFG ['lang '] = $ lang; // language parameter passed through URL}/* load language file */require (ROOT_PATH. 'AGES /'. $ _ CFG ['lang ']. '/common. php '); // if (! Empty ($ _ GET ['set _ lang ']) {setcookie ('lang', $ _ CFG ['lang '], time () + 30*24*3600 );}
