This code is incredibly useful for going through an array and applying changes to the individual values without having to create a specific loop to perfom this action. In this example all apostrophes are escaped.

// Walk through the array and escape all apostophes (anonymous function)
array_walk($merged_config, function(&$value, &$key) {
    $value = str_replace("'", "\\'", $value);
});

this also works, without the &$key

// Walk through the array and escape all apostophes (anonymous function)
array_walk($merged_config, function(&$value) {
    $value = str_replace("'", "\\'", $value);
});

keep the '&' it is important. This creates a reference to the object in memory.

When testing the translation system on QWcrm I needed to try different locales (languages) to see if the software actually worked how it should. The following are ways to change the HTTP_ACCEPT_LANGUAGE header that the browser sends to the webhost with its request.

FireFox

This will also fix the issue where Firefox was sending en-US instead of en-GB

Option 1 - Change the browser system settings

• Goto (Tools menu --> Settings --> Content --> Languages)
• Add English/United Kingdom [en-gb]
• (optional) remove the other version of english. I do not know if this would cause issues so i have left them

Option 2 - re install

You can also just install Firefox with the correct locale.

Option 3 - Plugins

Using a plugin will allow you to easily change the settings on a temporary basis.

Chrome

Option 1 - Change the browser system settings

• In the address bar type chrome://settings/ or click the 3 balls button-->settings
• Open advanced section at the bottom
• Goto languages
• Install 'English (United Kingdom)' language
• with 'English (United Kingdom)':
  • move to the top so it is first in the order of preference
  • set 'Display Google Chrome in this language'
  • set it as the language for spell checking
• (optional) remove the other version of english. I do not know if this would cause issues so i have left them

This is useful when you want to control the errors outputted tot he screen or is a class or some other code is not behaving as expected, such as the ADOdb error class.

The following code will preserve the current error reporting level so once your code has finished running the system's error reporting will be returned to its normal state.

// Get current PHP error reporting level
$reporting_level = error_reporting();

// Disable PHP error reporting (works globally)
error_reporting(0);

// Add you code here

// Re-Enable PHP error reporting
error_reporting($reporting_level);

What is Composer?

This needs to be cleared up for us newbies. and to start with you will come across the following statements which are both true.

• Composer is not a package manager
• Composer is a dependency manager

Composer is not a package manager because you are not downloading complete software packages but dependencies/libraries for your own software package.

Composer is a cross-platform software package that can is used to manage libraries for your PHP software project allowing you to install, update and remove libraries/dependencies from a single point reducing the need to manually update all of the dependecies individually which reduces time and makes it easier to keep things upto date. composer calls on its own library to get the latest updates of the various depencies. A vendor of software can make their software available from this library for others to use.

It is composer of the program mentioned above to manage your dependecies and also a small library to control autoloading of classes and other things.

Composer is useful because some packages use mulitple dependancies to get them to work and composer allows you to always get the latest version of all of the packages, or specify package numbers for your project. This process also correctly sets up all the required includes up as needed. This can reduce the time needed to update all of the packages.

The Wonderful World of Composer - YouTube - This is brilliant video that will explain Composer completely.

How does it Work?

• Installing Windows Composer  does the following
  • Installs Composer
  • Puts the Composer binary into path
  • autodetects your php.exe and allows you to choose which if you have more than one.
• Files
  • Composer installs all of the libraries usually to a folder called /vendor/ and is controlled by a single JSON text file which is parsed by the particular version of Composer you are using.
  • Each package that is downloaded is registered with the Composer framework.
  • There is sha-1 string for both the whole 'Composer vendor library' and for the inidividual dependencies which are stored in the composer.lock file. this allows the tracking of the various assets to see if they have been updated or just to compare against packages withing the Packagist repository.
  • composer.json - Is the control files used for the composer packages used within your project. This file allows multiple packages to be downloaded and combined
  • The standard folder to use is /vendor/
  • All dependecies will be installed into the vendor folder. they all have a unique name so collisions will not be an issue.
• Commands
  • Run the command  composer install in the folder where you want you dependencies to be installed and if the composer.json file is present it will use it for instruction.
  • I can install motranslator by navigating to where i want it and typing composer require phpmyadmin/motranslator as you can see this has the require command in the string.
  • This gets the latest stable version of the called software, in the case motranslator - composer require phpmyadmin/motranslator
  • composer require phpmyadmin/motranslator from the Windows commandline will add this dependency to your Composer library, or build a new library if there is not one already there.
• You only need to include the autoload.php once in your software project and composer will load all dependancies. This is all you need in your PHP project to get Composer.

  require vendor/autoload.php

When using mPDF to generate a PDF from a template it renders one or more tables and the fonts within them smaller than what they are in the template.

Cause

Look at the code below:

<!-- Invoice details -->
<td valign="top" align="right" width="200">
    <table border="0" cellpadding="3" cellspacing="0" style="border-collapse: collapse;">
        <tr>
            <td valign="top" width="90%" align="right"></td>
            <td align="top" class="olotd5" width="200">
                <table width="180" border="1" cellpadding="0" cellspacing="0" style="border-collapse: collapse;">
                    <tr>
                        <td>
                            <b>{t}Invoice ID{/t} - </b>{$invoice_details.invoice_id}<br>
                            <b>{t}Status{/t} - </b>{$workorder_details.status}<br>
                            <b>{t}Date{/t} - </b>{$invoice_details.date|date_format:$date_format} <br>
                            <b>{t}Due Date{/t} - </b>{$invoice_details.due_date|date_format:$date_format}<br>
                            <b>{t}Work Order{/t} - </b>{$invoice_details.workorder_id}<br>
                            <b>{t}Technician{/t} - </b>{$employee_details.display_name}<br>                                        
                            <b>{t}Credit Terms{/t} - </b>{$customer_details.credit_terms}<br>                                       
                        </td>
                    </tr>
                </table>
            </td>
        </tr>
    </table>
</td>

 and you can see this line.

<td valign="top" width="90%" align="right"></td>

mPDF cannot handle this empty cells with sizing statements.

Solution

I removed this line and then the template was rendered correctly.

These are some notes I made while integrating dhtmlxCombo into QWcrm.

• in the package the code you want is ../codebase/
• this codebase is prefilled with the dhxcombo_material skin
• you don't need ../codebase/dhtmlxcombo_deprecated.js
• you dont need ../codebase/fonts/ ? - doesnt seem to be called for what i use
• fontawesome, dunno what this is for, again, something else
• to add a new skin goto ../skins/ and into the folder of the skin you want. copy these files to ../codebase/ - the css will be overwritten
• for QWcrm I use skyblue
• only these JS and CSS are needed
  

  <script src="/{$theme_js_dir}dhtmlxcombo/dhtmlxcombo.js"></script>
  <link rel="stylesheet" href="/{$theme_js_dir}dhtmlxcombo/fonts/font_roboto/roboto.css"/>
  <link rel="stylesheet" href="/{$theme_js_dir}dhtmlxcombo/dhtmlxcombo.css">

• roboto.css is for foreign characters, it might be used - cant be sure. i have not needed it yet
• If existing select object was defined as parent - dhtmlxCombo will take all data from it (list of options, sizes, tabindex, name)

Example code I used in QWcrm

// This Call Transforms the Select Element by ID to a real Combo Box
var combo = dhtmlXComboFromSelect('description['+ iteration+']');

// This Call Transforms the Select Element by ID to a real Combo Box
 var combo = dhtmlXComboFromSelect('rate['+ iteration+']');

• The code above auto resizes the combobox
• var combo = can be removed unless you want to add options

var combo = dhtmlXComboFromSelect('rate['+ iteration+']');
combo.setSize(90);             // This sets the width of the combo box and drop down options width
//combo.setOptionWidth(200);    // this sets the width of the options drop down ONLY
