Can somebody explain me difeerence between
Request::is()
and
Request::patch()
??
I used request::is in my code to active navbar like this, but i saw that somebody use too request::patch
<div class="nav-collapse">
<ul class="nav">
<li class="{{ Request::is('/') ? 'active' : ''}}"><a href="/">#
</a</li>
#foreach($categories as $category)
<li class="{{ Request::is($category->name) ? 'active' : '' }}">
{{$category->name}}</li>
#endforeach
</ul>
</div>
In Side patch Request :
patch request says . only send the data which one you want to update
and it won't effecting or changing other data . so no need to send all
value again . just i want to update my first name so i need to send
only first name to update .
In Side Is Request :

I'm making an E-commerce website and in the products section (inside admin), I was trying to display only 10 products per page. I'm new to Spring and while writing the code, I encountered an error (given in title) when trying to add the next page button. However, the code works fine with the Previous button and all the page numbers. Here's my code for the pagnation section:
<nav class="mt-3" th:if="${count > perPage}">
<ul class="pagination">
<li class="page-item" th:if="${page > 0}">
<a th:href="#{${#httpServletRequest.requestURI}} + '?page=__${page-1}__'" class="page-link">Previous</a>
</li>
<li class="page-item" th:each="number: ${#numbers.sequence(0, pageCount-1)}" th:classappend="${page==number} ? 'active' : ''">
<a th:href="#{${#httpServletRequest.requestURI}} + '?page=__${number}__'" class="page-link" th:text="${number+1}"></a>
</li>
<li class="page-item" th:if="${page pageCount-1}">
<a th:href="#{${#httpServletRequest.requestURI}} + '?page=__${page+1}__'" class="page-link">Next</a>
</li>
</ul>
</nav>
The first 2 li's work fine and I get the list of pages and also the previous button. But on adding the Next button, I get the error mentioned above.
First of all, please always provide the actual error message. Otherwise we are just guessing.
My guess is that th:if expects a boolean expression and what you have doesn't look like boolean to me: th:if="${page pageCount-1}"
Change that to something like page == pageCount-1, but again depends on what you want to display there
i have a nav bar that i am using as a template.. see pic
if i am on any of the tabs then i want home to show. But if i am on the home page i don't want Home tab to show its redundant. i cant seem to figure out how to write the thymleaf code..
i have something like this the first line is what i am interested in fixing... can you please help with the controller part also i am sure i can do a model.addAttribute line in each method call and set the isActive to true except the home method i can set the isActive to false ... thank you
li th:text="${isActive} ? 'Home : "
<li th:text="${isActive} ? '<a th:href="#{/}">Home</a> : " </li>
<li><a th:href="#{/about}">About</a></li>
<li class="auctions">Auctions <i class="fas fa-caret-down"></i>
<ul>
<li>Current Auctions</li>
<li>Register</li>
</ul>
</li>
<li><a th:href="#{/contact}">Contact</a></li>
<li><a th:href="#{/locations}">Locations</a></li>
you can use this in controller:
model.addAttribute("isActive",true);
and use this in html code:
<li th:if="${isActive == null || !isActive}"><a th:href="#{/}">Home</a></li>

I'm using a Laravel 5.7 in an old web project last year 2019 but now I encountered a very weird bug.
This is a website that when you add a new game, it will show to the menu list and if it is featured it will show to the homepage content.
this is the table ['game_id', 'name', 'key', 'status', 'order', 'is_featured']
in the header view I put this code:
<ul class="nav-menu">
<li class="{{ ($page == "games" ? 'menu-active' : '') }} submenu dropdown"><a href="/games" >Games</a>
<ul class="dropdown-menu">
#foreach(GetPublishedGames() as $game)
<li class="nav-item">{{$game->name}}</li>
#endforeach
</ul>
</li>
...
calling this helper code GetPublishedGames()
function GetPublishedGames(){
$data = DB::table("game")->where("status", 1)->orderBy("order")->get();
return $data;
}
in the homepage controller I had this line
"feat_games" => Game::where("status", 1)->where("is_featured", 1)->orderBy("order")->limit(5)->get(),
that calls in the homepage view:
#if(count($feat_games))
#foreach($feat_games as $feat_game)
<div class="feat-game-item wow fadeInUp">
... some content ...
</div>
#endforeach
#endif
I have no idea why this happening, it works before in the local and development stage. I did tried to clear cache.
any idea?
I have faced a typical problem. The problem is which controller data object being executed in view page. Here the data object is $items. I have looked most of controller but can not find data object $items . Please help me to find it. Thank in advance. The portion of view page :
#foreach($items as $item)
<div class="partner-logo">
<div class="inner-div red-box">
<p>
<img src="{{ ($item->image) ? asset('file/images/' . $item->image) : "" }}" alt="" />
</p>
<h3>
<a
href="{{ isset($item->url) ?route('page.content.show', $item->url) : "#" }}"> {{ $item->title }}
</a>
</h3>
</div>
</div>
#endforeach
In Laravel, controllers usually pass their data to views in this format:
return view('nameOfView', [
'firstParam' => $firstParam,
'secondParam' => $secondParam,
'etc' => $etc
]);
So you can search in your controllers for the view name and then for the parameter name (in this case $items). If there are multiple controller functions with the $items param and the same view, add a test param to each and see which one your view renders. You can also check in routes/web.php for the current URL you are on, and find the correct controller function that way.
I get link something like this : http://local.dev/blog/articles/2/Category12
#foreach($categories as $category)
<li>{{$category->title}} ({{ $category->count }})</li>
#endforeach
What i want is to set active class on li for category that im on. Any suggestion? Maybe i need to compare id from url and this in foreach. But how?
You can get ID of a category from URI with request()->segment(3):
<li {{ request()->segment(3) == $category->id ? 'class="active"' : '' }}>
yeild() in the <li> section as css class with a name and active it from the view layout. Like
<li class="#yield('mymenu')">
<a href="/blog/articles/{{$category->id}}/{{$category->slug}}">{{$category>title}} ({{ $category->count }})
</a>
</li>
In the view file
#section('mymenu', 'active')
So when you'll click on the link it will generate a class which name mymenu and when it will load to a view file then it will be active.
