How to add a YouTube search box to any website

First thing to do is -- just go to YouTube website and view the source of webpage and
search for <form, though it is clumsy and real tough to find the right code exactly needed for search. you can see the code similar to the one shown below.

<form id="search-form" action="/results" method="get" name="searchForm">

<input id="search-term" name="search_query" type="text" onkeyup="goog.i18n.bidi.setDirAttribute(event,this)" value="" maxlength="128" />

<select class="search-type" name="search_type">

<option value="">Videos</option>

<option value="search_users" >Channels</option>

</select>

<input id="search-button" type="submit" value="Search" />

</form>

Just by removing the unnecessary code that is not at all required to us we can simplify the above code to

<form action="/results" method="get">
<input name="search_query" type="text" maxlength="128" />
<select name="search_type">
<option value="">Videos</option>
<option value="search_users">Channels</option>
</select>
<input type="submit" value="Search" />
</form>

Now just replace form attribute action="/results" to action="http://www.youtube.com/results"

<form action="http://www.youtube.com/results" method="get">

To open the results in a new tab or window add attribute target="_blank"

<form action="http://www.youtube.com/results" method="get" target="_blank" >

Complete code:

<form action="http://www.youtube.com/results" method="get" target="_blank" >
<input name="search_query" type="text" maxlength="128" />
<select name="search_type">
<option value="">Videos</option>
<option value="search_users">Channels</option>
</select>
<input type="submit" value="Search" />
</form>

Output:

Videos Channels

You can apply what ever styling you want and even make it more good looking(than youtube ;) )

Thank you.
