change bootstrap grid direction dynamically ( ltr to rtl or reverese)

We are making a site which will work both Rtl and Ltr ( En and Fa ).

We want to use tweeter bootstrap (3.*) .

Our mvc is made upon php .

Is it possible to use bootstrap which it's grid flow order is Rtl if the site language is fa , and use Ltr when the language is English ?

By language , I mean this : www.example.com/en or www.example.com/fa

when it is /en , we must use bootstrap which is Ltr (Left to right )

when it is /fa , we must use bootstrap which is Rtl (Right to left)

I know there are some bootstrap themes that I can use which are Rtl , but how can I use both rtl and ltr and changed within them dynamically ? ( maybe after a page refresh site direction goes Rtl or Ltr !!) ?

You can modify CSS rules "on the fly", attached here is a function, it modifies the major classes for Bootstrap 3 like col-(xs|sm|md|lg)-(1-12), col-(xs|sm|md|lg)-push-(1-12), col-(xs|sm|md|lg)-pull-(1-12), col-(xs|sm|md|lg)-offset-(1-12), there are many more classes to be modified but i needed only those.

All you need to do is call the function layout.setDirection('rtl') or layout.setDirection('ltr') and it will change the CSS Rules.

Should work on all browsers (IE>=9).

        var layout = {};
        layout.setDirection = function (direction) {
            layout.rtl = (direction === 'rtl');
            document.getElementsByTagName("html")[0].style.direction = direction;
            var styleSheets = document.styleSheets;
            var modifyRule = function (rule) {
                if (rule.style.getPropertyValue(layout.rtl ? 'left' : 'right') && rule.selectorText.match(/\.col-(xs|sm|md|lg)-push-\d\d*/)) {
                    rule.style.setProperty((layout.rtl ? 'right' : 'left'), rule.style.getPropertyValue((layout.rtl ? 'left' : 'right')));
                    rule.style.removeProperty((layout.rtl ? 'left' : 'right'));
                }
                if (rule.style.getPropertyValue(layout.rtl ? 'right' : 'left') && rule.selectorText.match(/\.col-(xs|sm|md|lg)-pull-\d\d*/)) {
                    rule.style.setProperty((layout.rtl ? 'left' : 'right'), rule.style.getPropertyValue((layout.rtl ? 'right' : 'left')));
                    rule.style.removeProperty((layout.rtl ? 'right' : 'left'));
                }
                if (rule.style.getPropertyValue(layout.rtl ? 'margin-left' : 'margin-right') && rule.selectorText.match(/\.col-(xs|sm|md|lg)-offset-\d\d*/)) {
                    rule.style.setProperty((layout.rtl ? 'margin-right' : 'margin-left'), rule.style.getPropertyValue((layout.rtl ? 'margin-left' : 'margin-right')));
                    rule.style.removeProperty((layout.rtl ? 'margin-left' : 'margin-right'));
                }
                if (rule.style.getPropertyValue('float') && rule.selectorText.match(/\.col-(xs|sm|md|lg)-\d\d*/)) {
                    rule.style.setProperty('float', (layout.rtl ? 'right' : 'left'));
                }
            };
            try {
                for (var i = 0; i < styleSheets.length; i++) {
                    var rules = styleSheets[i].cssRules || styleSheets[i].rules;
                    if (rules) {
                        for (var j = 0; j < rules.length; j++) {
                            if (rules[j].type === 4) {
                                var mediaRules = rules[j].cssRules || rules[j].rules
                                for (var y = 0; y < mediaRules.length; y++) {
                                    modifyRule(mediaRules[y]);
                                }
                            }
                            if (rules[j].type === 1) {
                                modifyRule(rules[j]);
                            }

                        }
                    }
                }
            } catch (e) {
                // Firefox might throw a SecurityError exception but it will work
                if (e.name !== 'SecurityError') {
                    throw e;
                }
            }
        }

Simply change float:left; to float:right; in grid system when html tag has dir='rtl'.

Here is the css:

html[dir="rtl"] .row > .col-xs-1, html[dir="rtl"] .row > .col-xs-2, html[dir="rtl"] .row > .col-xs-3, html[dir="rtl"] .row > .col-xs-4, html[dir="rtl"] .row > .col-xs-5, html[dir="rtl"] .row > .col-xs-6, html[dir="rtl"] .row > .col-xs-7, html[dir="rtl"] .row > .col-xs-8, html[dir="rtl"] .row > .col-xs-9, html[dir="rtl"] .row > .col-xs-10, html[dir="rtl"] .row > .col-xs-11, html[dir="rtl"] .row > .col-xs-12 {
  float: right;
}
@media (min-width: 768px) {
  html[dir="rtl"] .row > .col-sm-1, html[dir="rtl"] .row > .col-sm-2, html[dir="rtl"] .row > .col-sm-3, html[dir="rtl"] .row > .col-sm-4, html[dir="rtl"] .row > .col-sm-5, html[dir="rtl"] .row > .col-sm-6, html[dir="rtl"] .row > .col-sm-7, html[dir="rtl"] .row > .col-sm-8, html[dir="rtl"] .row > .col-sm-9, html[dir="rtl"] .row > .col-sm-10, html[dir="rtl"] .row > .col-sm-11, html[dir="rtl"] .row > .col-sm-12 {
    float: right;
  }
}
@media (min-width: 992px) {
  html[dir="rtl"] .row > .col-md-1, html[dir="rtl"] .row > .col-md-2, html[dir="rtl"] .row > .col-md-3, html[dir="rtl"] .row > .col-md-4, html[dir="rtl"] .row > .col-md-5, html[dir="rtl"] .row > .col-md-6, html[dir="rtl"] .row > .col-md-7, html[dir="rtl"] .row > .col-md-8, html[dir="rtl"] .row > .col-md-9, html[dir="rtl"] .row > .col-md-10, html[dir="rtl"] .row > .col-md-11, html[dir="rtl"] .row > .col-md-12 {
    float: right;
  }
}
@media (min-width: 1170px) {
  html[dir="rtl"] .row > .col-lg-1, html[dir="rtl"] .row > .col-lg-2, html[dir="rtl"] .row > .col-lg-3, html[dir="rtl"] .row > .col-lg-4, html[dir="rtl"] .row > .col-lg-5, html[dir="rtl"] .row > .col-lg-6, html[dir="rtl"] .row > .col-lg-7, html[dir="rtl"] .row > .col-lg-8, html[dir="rtl"] .row > .col-lg-9, html[dir="rtl"] .row > .col-lg-10, html[dir="rtl"] .row > .col-lg-11, html[dir="rtl"] .row > .col-lg-12 {
    float: right;
  }
}

I'll give you some hint for scripting this in JavaScript until the native support in feature versions of Bootstrap framework. you can use pull and push features in grid system in Tweeter Bootstrap. for changing the order of grids. here's an example:

<div class="row">
  <div class="col-md-9 col-md-push-3">.col-md-9 .col-md-push-3</div>
  <div class="col-md-3 col-md-pull-9">.col-md-3 .col-md-pull-9</div>
</div>

You can create a script to check the language and add appropriate push and pull classes to the grids.

Have you tried just flipping all float:left; to float:right on the major grid entities and serving that as a Rtl specialized CSS file / override?
