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.

Search is not working

• make sure there is nothing in the 'File Name Patterns' box
• mark text can cauyse some issues so go to options->editor->marked occurances, then off/on
• reboot netbeans
• make sure you have the correct scope selected

Regex search

These are some examples of searches in netbeans using a Regex pattern

So i want to change some <input> tags.

<input .....>
to
<input ..... />

 The following will search for all <input strings that do not terminate in />

Search String:
<input(.*)([^\/])>

Replacement String:
<input$1$2 />

However this does not take into account of whether there is a space at the end so I need to do another search for:

<input(.*)({space}){2}\/>  - needs finishing

Notes

• ^ is a 'not' character when within []

  [^\/]

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

This is a standard menu layout that ustilises the Joomlashine framework for its fluid structure but could easily be adapted to bootstrap.

Demo

This will not look right because the columns are not fluid due to theri being no JSN Framework installed, but it will give you an idea.

The Example Menu

If you have any allergy requirements ask to speak to the chef.

All our meals are cooked to order so during busy times there may be a wait, this is because everything is as fresh as possible and has been sourced locally where possible.

After upgrading your Joomla install you get the one of following or similiar error:

• Error displaying the error page: Unknown column 'a.client_id' in 'where clause': Unknown column 'a.client_id' in 'where clause'

• 1054 Unknown column 'client_id' in 'field list'

Cause

This is cause by the finalising scripts being run for some reason. I think the joomla team know about this and is probably fixed by now.

Solution

I ran the Joomla upgrade and then the error 1054 occurs

• I kept the windows open and did not click on anything
  http://www.example.com/administrator/index.php?option=com_joomlaupdate&view=update&layout=finaliseconfirm
• I opened a new window in which i loaded the page
  http://www.example.com/administrator/index.php?option=com_installer&task=database.fix
• This found issues and fixed them - it said the 'fields_groups' table was missing, perhaps add this in before running the upgrade.
• I went back to the other window and refreshed the page and it loaded to the 'login and cleanup page'
  http://www.example.com/administrator/index.php?option=com_joomlaupdate&view=update&layout=finaliseconfirm
  i logged in

Menu Items are missing

• after research i came across thess threads which said this script had not run script for some reason. it is for 3.7.0 but i used it for 3.8.0 as the code looks what is needed.

  • https://github.com/joomla/joomla-cms/issues/15719
  • The Script: https://github.com/joomla/joomla-cms/blob/staging/administrator/components/com_admin/sql/updates/mysql/3.7.0-2017-01-17.sql
• Re-Run 'fix database' just in-case

Done
