How to add a carousel as background in bootstrap4? - php

I am building a simple website with bootstrap4 and I am trying to set a carousel as the background. Is there any simple way to do it without keyframes?

You can use bootstrap default carousel with some tweaks, namely the z-index and position attributes.
Image 1, 2 and 3 must be replaced by your own images, without them it will not work very well and the size adapted to your needs, you can also add indicators for the image and arrows cycle through images.

Uncaught error while generating qrcode with "endroid/qr-code" library

I am creating a qr-code generator program with PHP, and I am using a library called qr-code. I have gotten to the point where I have successfully gotten the string the user wishes to convert into a qrcode, at the point to generate the qrcode I get the following error :
Uncaught Error: Call to a member function getContentType() on null in index.php:13 Stack trace: #0 {main} thrown in index.php on line 13
I have been at this for a while now, and I am stuck. There is really now in-depth documentation for the library in question, Please help me out. Here is my code :
<?php
require __DIR__ . '/vendor/autoload.php';
use Endroid\QrCode\QrCode;
// Get url from form
if (isset($_GET['submit'])) {
$url = strval($_GET['url']);
echo gettype($url);
$qrcode = new QrCode("$url");
echo "</br>";
header('Contert-Type: application/' . $qrCode->getContentType());
$createCode = $qrCode->writeString();
}
?>

Here is a link to the library
You are trying to use $qrCode which does not exist, look at your code carefully:
$qrcode = new QrCode("$url");
echo "</br>";
header('Contert-Type: application/' . $qrCode->getContentType());
$createCode = $qrCode->writeString();
First you use $qrcode then you use $qrCode (which does not exist).
Change the first line to:
$qrCode = new QrCode("$url");

The issue is the 10px padding-bottom.
In file n7.css , line 31, you'll see the following:
#content {
background-color: #ffffff;
padding-bottom: 10px;
}
Change by:
#content {
background-color: #ffffff;
padding-bottom: 0px;
}
Let me know how it goes.
The reason of problem here;
#content {
background-color: #ffffff;
padding-bottom: 10px;
}
But I see, "you are not very familiar with css" so this code is in a file of your server (http://i2.silvergames.com/css/n7.css). Please go there, find the code above and change:
#content {
background-color: #ffffff;
padding-bottom: 0px;
}
That's all.

Displaying content based on user session PHP

* I've solved this. Thanks for the help /*
I am attempting to show some images to different users depending on their user_id / username.
I am trying to do so by using userSession.
I tried by using this code:
<?php
if ($_SESSION['user_id'] == 'Charlie') {
// do admin
<li class="span4 gallery-item" data-id="id-1">
<img class="fancybox" src="img/photoshop2_small.jpg" data-big="img/photoshop2.jpg" /> </li>
}
?>
I also tried "userSession" and "user_email". None worked.
It cannot even load my website when I type in the code above. When I remove it, it loads perfectly.
Here's my home.php class which is the one that loads when a user is logged in. It's the same for everything atm but I am trying to display just certain images to the users depending on who they are. They have no special rank or anything.
<?php
session_start();
include_once 'dbconnect.php';
if(!isset($_SESSION['userSession']))
{
header("Location: index2.php");
}
$query = $MySQLi_CON->query("SELECT * FROM users WHERE user_id=".$_SESSION['userSession']);
$userRow=$query->fetch_array();
$MySQLi_CON->close();
?>

You never changed the session data in your example code. You should do something like:
$_SESSION['user_id'] = $userRow['user_id']
to set the concerning session var.
try this code instead of yours:
<?php
if ($_SESSION['user_id'] == 'Charlie') { ?>
// do admin
<li class="span4 gallery-item" data-id="id-1">
<img class="fancybox" src="img/photoshop2_small.jpg" data-big="img/photoshop2.jpg" /> </li>
<?php } ?>
EDIT if user ID is unique and not depended on letters casing you can do
if (strtolower($_SESSION['user_id']) === 'charlie')

Creating a row that spans the width of the screen using bootstrap

I am trying to create a layout similar to this one where the different sections span the entire width of the screen. I was looking at the html/css for the layout and couldn't figure out why my view was not doing the same. (I am relatively new to creating pages).
I am using php to make creating the pages easier so I have a few files.
.jumbotron{
background: gray;
height: 50%;
margin-top: 10px;
}
.jumbotron p, h1 {
text-align: center;
}
.nav {
text-align: center;
padding: 0;
margin: 0;
background-color: red;
height: 10%;
}
.nav li {
display: inline-block;
margin-right: 5%;
margin-left: 5%;
}
.container #about {
background: blue;
height: 50%;
}
.container #me {
background: blue;
height: 50%;

The rows don't extend to the edge of the screen. The views are also not aligned. I know it is a lot to look at, but I could not find any resource online with an example, or a simple template for me to take a look at.
In Bootstrap you can put the 12 column grid in a .container or a .container-fluid. The first is used if you want to grid to span a maximum of 1170 pixels, the latter if you want it to span the entire screen. Both have a horizontal padding of 15 pixels on each side to keep its content have some distance from the edge of the screen. For text this is a good thing to have, however as you note it's nice if a background color or image does span the entire width.
If you take a look at the theme you linked (see http://ironsummitmedia.github.io/startbootstrap-freelancer/) you might notice that the .container and .container-fluid classes they use also don't span the entire width of the screen. They surround them with other elements, e.g. <section class="success" id="about">, on which they put a background color.
See this example where i've put a <section> with a .pink or .green background color around the containers:
.pink {
background-color: #f99;
}
.green {
background-color: #9f9;
}
section {
padding-bottom: 20px;
}
<link href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css" rel="stylesheet" />
<section class="pink">
<div class="container-fluid">
<div class="row">
<div class="col-xs-12"><h3>.container-fluid</h3></div>
</div>
<div class="row">
<div class="col-xs-6">Column one</div>
<div class="col-xs-6">Column one</div>
</div>
</div>
</section>
<section class="green">
<div class="container">
<div class="row">
<div class="col-xs-12"><h3>.container</h3></div>
</div>
<div class="row">
<div class="col-xs-6">Column one</div>
<div class="col-xs-6">Column one</div>
</div>
</div>
</section>
P.S. in your example the <a> tags aren't closed with a </a> tag, plus the .container after the .jumbotron isn't closed.
The problem with extending rows is simple, add the following rule:
body {
margin: 0;
}

How can I align the span's exactly, so that it looks like a perfect gallery like structure.
I don't want to use any plugin here or jQuery.
Use a row instead of row-fluid..
<div class="container">
<div class="row">
<div class="span3">
<a href="#" class="thumbnail">
<img src="https://www.gstatic.com/webp/gallery/4.sm.jpg" alt="sample" style="border:solid 2px red;">
</a>
</div>
...
</div>
</div>

Did you try to add a new <div class="row-fluid"> ... </div> every four images ?
