Combined two Search Forms - not functioning

[chrisj]

Thanks for all the previous help. The web script that I’m modifying has a Search Form that successfully appears when a particular type of page displays:

<?php if (preg_match('#/?sub__(\d)+\b#',$_SERVER['REQUEST_URI'],$matches)) {
echo "<form action='#' method='POST' id='sub_id'>
<input name='search_sub'>
<input type='submit' value='search' />
<input type='hidden' value='{$matches[1]}'> </form>";
} ?>

I wanted to enhance the Form’s appearance and tested this HTML Search Form (which slides the text enter field across the page upon selecting the magnify glass icon) seperately successfully:

<div id="sb-search" class="sb-search " >
    <form>
        <input class="sb-search-input " onkeyup="buttonUp();" placeholder="Enter your search term..." onblur="monkey();" type="search" value="" name="search" id="search">
        <input class="sb-search-submit" type="submit"  value="">
        <span class="sb-icon-search"><i class="fa fa-search"></i></span>
    </form>
</div>

the HTML Search Form has this corresponding js:

function buttonUp(){
         var valux = $('.sb-search-input').val();
            valux = $.trim(valux).length;
            if(valux !== 0){
                $('.sb-search-submit').css('z-index','99');
            } else{
                $('.sb-search-input').val('');
                $('.sb-search-submit').css('z-index','-999');
            }
    }

    $(document).ready(function(){
        var submitIcon = $('.sb-icon-search');
        var submitInput = $('.sb-search-input');
        var searchBox = $('.sb-search');
        var isOpen = false;

        $(document).mouseup(function(){
            if(isOpen == true){
            submitInput.val('');
            $('.sb-search-submit').css('z-index','-999');
            submitIcon.click();
            }
        });

        submitIcon.mouseup(function(){
            return false;
        });

        searchBox.mouseup(function(){
            return false;
        });

        submitIcon.click(function(){
            if(isOpen == false){
                searchBox.addClass('sb-search-open');
                isOpen = true;
            } else {
                searchBox.removeClass('sb-search-open');
                isOpen = false;
            }
    });
});

I’ve combined the two Search form codes successfully like so:

<?php
if (preg_match('#/?sub__(\d)+\b#',$_SERVER['REQUEST_URI'],$matches)) {
echo "<form action='#' method='POST' id='sub_id'>
<input class='sb-search-input ' onkeyup='buttonUp();' placeholder='Enter your search term...' onblur='monkey();' type='search' value='' name='search_sub' id='search'>
<!--<input name='search_sub'>-->
<input class='sb-search-submit' type='submit' value=''>
<span class='sb-icon-search'><i class='fa fa-search'></i></span>
<!--<input type='submit' value='search' />-->
<input type='hidden' value='{$matches[1]}'>
</form>";
}
?>

however, now the search Form does not slide the text enter field across the page, it is just already ‘open’ when the page displays.

I’m looking for help with getting the text enter field to slide across the page upon selecting the magnify glass icon again, instead of it being ‘open’ (when the page displays).

If that makes sense I look forward to any assistance.
