Change the dynamic bootstrap direction (ltr to rtl or reverese)
We are creating a website that will work both Rtl and Ltr (En and Fa).
We want to use tweeter bootstrap (3. *).
Our mvc is made in php.
Is it possible to use bootstrap, which has a grid flow order: Rtl if the site language is fa, and use Ltr if the language is English?
By language , I mean this: www.example.com/en or www.example.com/fa
when it is / en we have to use bootstrap which is Ltr (left to right)
when it's / fa we have to use bootstrap which is Rtl (right to left)
I know there are some bootstrap themes I can use that are Rtl, but how can I use both rtl and ltr and dynamically change within them? (maybe after the site update page is directed to Rtl or Ltr!)?
You can change the CSS rules on the fly, there is a function attached here, it changes the core classes for Bootstrap 3, such as 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 that need to be changed, but I only need those.
All you have to do is call the function layout.setDirection('rtl')
or layout.setDirection('ltr')
and it will change the CSS rules.
Should work in 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;
}
}

Just change float:left;
to float:right;
in the grid when the tag html
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 a little hint for scripting in JavaScript until there is built-in support in functional versions of the Bootstrap framework. you can use pull and push functions on grid in Twetter Bootstrap. to change the order of the 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 test the language and add the appropriate push and pull classes to the grids.
