You have your php script and in your view file you can use AJAX to pass value on click.

<script src="http://code.jquery.com/jquery-1.8.0.js"></script>
<script type="text/javascript">
    function text()
    {
        var textVal=$("#busqueda_de_producto").val();
        $.ajax(
        {
            type:"POST",
            url:"index.php",  //here goes your php script file where you want to pass value
            data: textVal,
            success:function(response)
            {
               //what to do in case of response
            }
        });

        return false;
    }
</script>

and for the text input are do something like

<input type='text' name='busqueda_de_producto' id='busqueda_de_producto' value='' onclick="javascript:text();"/>
