AdminLte active current menu using JAVASCRIPT

AdminLte is the most popular and open source admin theme. many developers used AdminLte for developing admin panel. Many Developers use PHP if condition for active the current sidebar menu. It’s hard to manage with if condition when we have many sidebar menus.

I think we should use JAVASCRIPT for active the current menu for the sidebar. it’s too easy and simple js snippets.


    var url = window.location;
    // Will only work if string in href matches with location
    $('ul.nav a[href="'+ url +'"]').parent().addClass('active');

    // Will also work for relative and absolute hrefs
    $('ul.nav a').filter(function() {
        return this.href == url;

Just add above code into your javascript file. then checked the “active” class is add onto your current menu.

How to remove html tags from string using PHP

How to remove HTML tags from string programmatically. let’s see the two easy way to remove HTML tags from the string using “strip_tags” and “preg_replace”. So let’s see how to remove HTML code from the string using “strip_tags”.

$string = strip_tags(“Hello <b>world!</b>);

We used the ‘strip_tags’ function for removing the HTML tags from the string. so it’s very easy to remove HTML using “strip_tags”. But the “strip_tags” add space after removing the tags from the string like.

$string = strip_tags(“Hello<b>world!</b>);

The output of the above statement is “Hello world!” instead of “Helloworld!”. so let’s see the another trick for removing only HTML tags without adding the space.

$string = preg_replace(#<[^>]+>#’, ‘ ‘, ‘Hello<b>world!</b>’);

The output of the above function is “Helloworld!” instead of “Hello world!”.
