<h1>PHP Dynamic Qr code - v2.3.0</h1>

<small> Documentation - v2.3.0 / Last Update: 13/01/2025</small>

|
||
<h2> About PHP Dynamic Qr code</h2>
|
||
<p><b>PHP Dynamic Qr code </b> is a script that allows the generation and saving of dynamic and static QR codes. It has clean, responsive and user-friendly design. It is Based on <a href="https://adminlte.io/" target="_blank">AdminLte </a> the <i>"Best open source admin dashboard & control panel theme. Built on top of Bootstrap" </i> and <a href="https://github.com/chetans9/core-php-admin-panel" target="_blank">Core PHP Admin Panel,</a> a simple Admin Pannel written in core PHP that contains an implementation of general features you might need in your website admin panel like: record management (CRUD), secure authentication, pagination, filters.<br><br>
|
||
N.B. A <strong>careful reading</strong> of this documentation is recommended to fully understand how the script works.
|
||
</p>
|
||
|
||
<h2> What is a dynamic qr code</h2>
|
||
<p><strong>A Dynamic QR code has a modifiable destination URL.</strong><br> A Short URL is placed into the QR code which then transparently re-directs the user to the intended destination. The destination of a dynamic QR code can be changed at any time and as often as you want – even if your marketing material has already been printed. This will save reprinting costs, effort and enable you to respond to any changes in the campaign as quickly as possible.</p>
|
||
|
||
<h2> What is a static qr code</h2>
|
||
<p><strong>A Static QR code has a fixed destination URL.</strong><br> The information encoded in <b>static QR codes are fixed</b>. The destination/data is stored directly in the QR Code graphic (hence QR codes are also getting larger and form a more complex pattern if there is more data to store). Therefore, the stored destination/data cannot be changed. Any typo in an already printed QR code cannot be changed, as with any other printed material. <strong>Through this script you can create 13 different types of static qr code.</strong></p>

||

||
<div id="setup">
|
||
<h2> Setup</h2>
|
||
<p>You can choose between local installation (recommended for development) and docker installation (recommended for general use)</p>
|
||
<p><u>Local setup:</u></p>

<div id="upgrade">
|

<h2> Upgrade</h2>
|
||
<p>To upgrade the program from version 1.0 to version 2.x and maintain backward compatibility with the QR codes you have already created, files and users, you can follow these steps:</p>
|
||
<ol><strong>
|
||
<li>Clone the project from github</li>
|
||
<li>Edit config/environment.php with your database credential</li>
|
||
<li>Launch upgrade/upgrade.php file in your browser </li>
|
||
<p>The script makes the necessary changes in the database that adapt to the new source code.</p>
|
||
<li>Finish</li>
|
||
</ol>
|
||
</div>
|
||
|
||
<div id="multi-account">
|
||
<h2> Multi account</h2>
|
||
<p>Starting from version 2.x, the functionality that supports the creation and management of QR codes with the support of multiple accounts has been added</p>
|
||
<ol><strong>
|
||
<li>Superadmin accounts can manage all users, all qrcodes created</li>
|
||
<li>Admin accounts can only manage QR codes created by them and "universal" ones, i.e. not associated with any specific account</li>

<h2> Script Structure</h2>
|
||
<ol>
|
||
<li>General</li>
|
||
<p>
|
||
All pages include the <b>config.php</b> file which in turn includes the <b>helpers.php</b> file and the <b>MysqliDb class</b> and the <b>auth_validation.php</b> file which takes care of verifying on each page that the user is logged in (read authentication types).
|
||
</p>
|
||
|
||
<p>As for the HTML structure, all pages start by including the <b>head.php</b> page which contains the entire head tag, the <b>navbar.php</b> page, the <b>sidebar.php</b> page.
|
||
There is a header with the page title and then the different main content for each page. Finally, each page includes the <b>footer.php</b> file with the required js scripts; some pages have <b>additional js scripts</b> needed
|
||
|
||
As specified at the beginning, the frontend part of this script is done with <b>AdminLTE</b> (Bootstrap). We therefore recommend reading the official documentation to fully understand the HTML structure.
|
||
</p>
|
||
|
||
|
||
<li>Qr code and Admin users</li>
|
||
|
||
<p>
|
||
<b>The dashboard page has a separate structure</b>, while the dynamic qr codes, static qr codes and users sections have a <b>very similar structure</b> to each other:
|
||
</p>
|
||
<ol>
|
||
<li><strong>dynamic_qrcodes.php</strong>, <strong>static_qrcodes.php</strong>, <strong>users.php</strong> allow you to view the relevant data</li>
|
||
<li><strong>dynamic_qrcode.php</strong>, <strong>static_qrcode.php</strong>, <strong>user.php</strong> allow you to add, modify and delete the relevant data</li>
|
||
</ol>
|
||
|
||
</ol>
|
||
</div>
|
||
|
||
<p><strong>This script is designed as OOP as possible. Therefore, all QR code handling operations are performed using classes and methods. There are 3 classes for 3 the three sections (dynamic qrcodes, static qrcodes, users) and dynamic qrcodes, static qrcodes share a single Qrcode class which contains some methods used by both classes</strong></p>
|
||
|
||
<div id="dynamic-qrcode">
|
||
<h2> Dynamic Qr code</h2><br>
|
||
<p>The physical creation of a dynamic qr code is managed by a free external provider https://api.qrserver.com/</p>
|
||
</div>
|
||
|
||
<div id="static-qrcode">
|
||
<h2> Static Qr code</h2><br>
|
||
<p>The physical creation of a static qr code is managed by a free external provider https://api.qrserver.com/ and previously is managed differently depending on the type</p>
|
||
</div>
|
||
|
||
<div id="dashboard">
|
||
<h2>Dashboard</h2>
|
||
<p>The dashboard is the main page of the script. In this section there is a counter of the total number of qr code in the database, and in particular also the number of dynamic and static ones. There is also a counter regarding the number of <strong>scans of the dynamic qr code</strong>.<br>
|
||
The script offers 2 examples of dynamic charts created with chart.js
|
||
The first shows a weekly report of the number of qr codes created (dynamic and static), the second graph offers an overview of the number of scans of dynamic qr codes.
|
||
</div>
|
||
|
||
<div id="read">
|
||
<h2>What happens when i scan a dynamic qr code?</h2>
|
||
<p>When a dynamic QR code is scanned, the read.php page opens by default which increases the scan counter and takes care of carrying out the appropriate redirect.
|
||
|
||
You can change the name of this page by remembering to change the constant defined in config.php
|
||
|
||
You can also customize the redirect page and increase the timer

||
<div id="extra">
|
||
<h2>EXTRA</h2>
|
||
<p>My script is in constant development and I hope to expand it from time to time with more and more useful features, so stay tuned for the updates.<br> With the first version, in the classes that realize the 2 types of qr code, an additional method not mentioned in the above documentation called <strong>addLogo()</strong> is included.
|
||
|
||
To add this functionality you need to delete the comment characters inside the class and add the input fields to the forms for the user to upload the logo.
|
||
|
||
However, this feature is not recommended as it can cause different QR code scanning errors depending on the scanner applications.
