Note: Don’t touch the mouse settings in Preferences or it will override the above change.

split()

The split function is deprecated, it might still work for now but will output a warning. The split function can be “converted” in two different ways.

If the split is defined by using a character or simple strings like ‘:’ or “\r\n” it can be converted to explode(). The advantage of explode() being that it is slightly faster then using a regex based function.

If the split is defined by using a regex we have to convert it to using the regex comaptible preg_split() function.

To find occurrences you can use the regex search on [^\._\w]split\( 

single character => split to explode (when  regex ’\|’ convert to character ‘|’)

split(':', $value)  =>  explode(':', $value)

split(self::MULTI_DELIMITER, $value);  =>  
explode(self::MULTI_DELIMITER, $value);

character class or full regex => split to preg_split

split('[[:space:]]+', trim($uname))  =>
preg_split('/[[:space:]]+/', trim($uname))

split("\r?\n", $headers);  =>  preg_split("/\r?\n/", $headers);

split('(, *)|,', $keywordsString);  =>  
preg_split('/(, *)|,/', $keywordsString);

magic_quotes

Magic Quotes is mostly deprecated as of 5.3 and should be disabled by default on any serious PHP installation. Remove all lines containing to avoid warnings:

get_magic_quotes_runtime

set_magic_quotes_runtime

eregi()

Change eregi to preg_match and change the existing regex expression. Add slashes to the begining and the end of the existing regex and add the i option at the end to make it case-insensitive. Example: /existing regex/i

Make sure any existing forward slashes / in the existing regex are escaped with a backslash \ (ie: ‘x/y’ becomes ‘/x\/y/i’)

There is many changes to do but here is some examples:

eregi('Windows 9', php_uname())

=>

preg_match('/Windows 9/i', php_uname())

$reg = '^' . str_replace(array('*', '?', '/'), array('.*', '.', '\\/'), $fragment) . '$';
 return eregi($reg, $value);

=>

$reg = '/^' . str_replace(array('*', '?', '/'), array('.*', '.', '\\/'), $fragment) . '$/i';
return preg_match($reg, $value);

eregi('^(http|ftp)://', substr($file, 0, 10))
=>
preg_match('/^(http|ftp):\/\//i', substr($file, 0, 10))

ereg()

Same principle as eregi(). Change to preg_match and add slashes at the begining and the end of the existing regex. Don’t add the i option, ereg is not case sensitive.

ereg('^libc-(.*)\.so$', basename(readlink('/lib/libc.so.6')), $matches)
=>
preg_match('/^libc-(.*)\.so$/', basename(readlink('/lib/libc.so.6')), $matches)

gd_info() “JPG Support”

Look for calls to gd_info(); The “JPG Support” array key was changed to JPEG Support in PHP 5.3.

$gd_options = gd_info();
if (!$gd_options['JPG Support'] ) {

to

if ((!isset($gd_options['JPG Support']) || $gd_options['JPG Support'] != true) &&
(!isset($gd_options['JPEG Support']) || $gd_options['JPEG Support'] != true)) {

__toString()

In PHP 5.3 the __toString() magic method does not accept any parameters. Old code such as the one below will trigger a fatal error.

Fatal error: Method __tostring() cannot take arguments

Try a regex search for function[\s]+__toString\([^\)]+\) to find problematic code.

Changing

public function __toString(array $arrAttributes = array(), $valueSeparator=',') {
    $arrData = $this->toArray($arrAttributes);
    return implode($valueSeparator, $arrData);
}

to

public function __toString() {
    if(func_num_args() == 2) {
        return $this->__invoke(func_get_arg(0), func_get_arg(1));
    } elseif(func_num_args() == 1) {
        return $this->__invoke(func_get_arg(0));
    } else {
        return $this->__invoke();
    }
}

/**
 * Convert object attributes to string
 *
 * @param array $arrAttributes array of required attributes
 * @param string $valueSeparator
 * @return string
 */
public function __invoke(array $arrAttributes = array(), $valueSeparator=',') {
    $arrData = $this->toArray($arrAttributes);
    return implode($valueSeparator, $arrData);
}

dl()

Do a regex search for [^_\.\w]dl\( which should only match one or two files in the PEAR folder.

Replace

return @dl('php_'.$ext.$suffix) || @dl($ext.$suffix);

with

// return @dl('php_'.$ext.$suffix) || @dl($ext.$suffix);
// dl() is deprecated in php 5.3
return false;

PEAR

Some changes inside the PEAR folders to fix potential issues when it tries to install PEAR packages. However, in general I don’t think the PEAR that shipped with older Magento versions is quite ready for php 5.3. Most likely Magento Connect will not work as expected anymore once the website is moved to a server using php 5.3. This should not be a big problem since you can install your Magento extensions manually.

To fix the problem I added a fonts folder within my Mantis installation root, added the ARIAL.TTF font file inside that folder and then added a $g_system_font_folder variable to the mantis configuration file config_inc.php to point to the fonts folder.

Step by step guide

Open the Windows Fonts folder in your Control Panel

Double-click on Arial to open the contents

Select Arial Regular and right-click > Copy (or Ctrl+C)

Add a folder named fonts in the Mantis folder

Paste the Arial file into the fonts folder and rename arial.ttf file to upper case ARIAL.TTF

Add $g_system_font_folder = __DIR__ . '/fonts'; to config_inc.php

Last step is to upload config_inc.php and the fonts folder to your web hosting.

Magento Notice: Undefined index: 0  in .../htdocs/app/code/core/Mage/Core/Model/Mysql4/Config.php on line 92

Turns out this was due to a faulty import of the database. Apparently there are a few tables where using an id of 0 in the auto_increment column has a particular meaning and is intended. When restoring the MySQL dump through Navicat it replaced id values of 0 in auto_increment columns with new auto-incremented ids instead of 0 which broke Magento.

To fix this I simply dropped the whole database and reimported the dump using the official MySQL command line client (mysql -u username -p db_name < scrip.sql) and everything worked fine.

Seems that adding

-J-Dnetbeans.subversion.commit.deepStatusRefresh=false

To he netbeans configuration file will disable the automatic scan during the commit preparation phase. If for whatever reason  you end up changing a file outside Netbeans (external text editor, adding new pictures…) you cam simply go to the “Files” tab and right-click your projet and hit “Refresh Folder” to let it scan everything.

See http://wiki.netbeans.org/FaqNetbeansConf for information on how to change the netbeans configuration file.

By extracting the code from the cache management controller I was able to build a custom script that can be called via command line on the server and that will allow you to do a full cache refresh without any kind of time limit or connection timeout issues. The only requirement is shell access to your website files by SSH, Telnet or a terminal of some sort.

Put this file inside /app/ right next to the Mage.php file. To use it, you can simply navigate to the /app folder with your SSH client (or terminal if you run the website on your local PC) do php -f clearcache.php or for fastcgi adepts php-cgi -f clearcache.php

Call the file clearcache.php and you can comment out the parts you don’t need if you only want to refresh one kind of resource (ie: comment out the stock status try/catch block if you don’t want to refresh product stocks).

Theres an easy way to add your own theme folder and use it to customize the look of your admin control panel. All files that aren’t included in your theme will fall back to the default Magento theme, thus avoiding any problems with missing templates and making it a lot easier to change only a few files.

Add a new adminhtml theme

Start by adding a new folder inside the app/design/adminhtml/default folder. To start out, the folder should also contain one sub-folders called template.

So, for example, you add a folder called mytheme, and inside it you add another folder called template.

Overriding Magento configuration

All you have to do is add a new config.xml file inside app/code/local/MyCompany/Adminhtml/etc. Add the following code inside the file:

Note: if you created this file by following one of my earlier guides you don’t have to create it again and you would simply add the <stores> section at the appropriate location inside the existing file.

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <MyCompany_Adminhtml>
            <version>0.1.1</version>
        </MyCompany_Adminhtml>
    </modules>
    <stores>
        <admin>
            <!-- override default admin design package and theme -->
            <design>
                <package>
                    <name>default</name>
                </package>
                <theme>
                    <default>mytheme</default>
                </theme>
            </design>
        </admin>
    </stores>
</config>

You will also have to tell Magento about this new module in an XML file placed inside /app/etc/modules. This file could be called MyCompany.xml and inside you would copy/paste:

Note: if you created this file by following one of my earlier guides you don’t have to create it again.

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <MyCompany_Adminhtml>
	    <active>true</active>
            <codePool>local</codePool>
            <depends>
                <Mage_Adminhtml />
            </depends>
        </MyCompany_Adminhtml>
    </modules>
</config>

Changing template files

Now to change the default Magento templates you basically copy the .phtml files from the app/design/adminhtml/default/default/template folder into your own template folder and change the contents of the .phtml file to suit your needs.

For example, if you want to change the login box and remove the Magento copyright message:

Copy app/design/adminhtml/default/default/template/login.phml into the app/design/adminhtml/default/mytheme/template folder and then change the <p class=”legal”></p> to put your own legal note.

Create a new package under app/code/local , for this example lets make a “MyCompany” package. If you already have an existing package for your magento mods you can use that one but you will have to change all references to MyCompany in the following code.

Create folder app/code/local/MyCompany

Create a new module called “Adminhtml” containing a “Block” folder and a “etc” folder.

Create folder app/code/local/MyCompany/Adminhtml

Create folder app/code/local/MyCompany/Adminhtml/Block

Create folder app/code/local/MyCompany/Adminhtml/etc

Add a “Notification” folder inside the Block folder.

Create folder app/code/local/MyCompany/Adminhtml/Block/Notification

Create Toolbar.php inside the MyCompany/Block/Notification folder.

<?php
/**
 * Block all notifications
 */
class MyCompany_Adminhtml_Block_Notification_Toolbar extends Mage_Adminhtml_Block_Template
{
    public function isShow()
    {
	return false;
    }

    public function isMessageWindowAvailable()
    {
        return false;
    }
}

Create Window.php inside the MyCompany/Adminhtml/Block/Notification folder.

<?php
/**
 * Prevent popup window
 */
class MyCompany_Adminhtml_Block_Notification_Window extends Mage_Adminhtml_Block_Notification_Window
{
    public function canShow()
    {
        return false;
    }
}

Create config.xml file inside the MyCompany/Adminhtml/etc folder

<?xml version="1.0" encoding="UTF-8"?>

<config>

    <modules>
        <MyCompany_Adminhtml>
            <version>0.1.0</version>
        </MyCompany_Adminhtml>
    </modules>

    <global>

        <blocks>
          <adminhtml>
              <rewrite>
             	  <notification_window>MyCompany_Adminhtml_Block_Notification_Window</notification_window>
		  <notification_toolbar>MyCompany_Adminhtml_Block_Notification_Toolbar</notification_toolbar>
              </rewrite>
          </adminhtml>
        </blocks>

    </global>

</config>

Last but not least, you have to create a new Modules XML file to load your module. Create MyCompany.xml inside the app/etc/modules folder.

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <MyCompany_Adminhtml>
	    <active>true</active>
            <codePool>local</codePool>
            <depends>
                <Mage_Adminhtml />
            </depends>
        </MyCompany_Adminhtml>
    </modules>
</config>

1. Click File->New…->Other…

2. Click on the Java folder and select Existing project using Ant buildfile….

3. Click next

4. A message should popup asking you if you want to enable Ant, click OK

5. Close the new project wizard, you don’t have to actually create a project.

Go to Window->Show View->Other…, the Ant view should now be in the list.

Enjoy
