Duplicated placeholder output

Issue:

  • Zend Framework placeholder (headTitle, headMeta, headLink, headScript, headStyle, inlineScript) creates twice or multiple title/meta/link/script tags in HTML.
  • Duplicated title/meta/link/script tags generated from Zend Framework placeholder.
  • e.g.:

    source:

    <?php echo $this->headScript()->appendFile("/scripts/global.js") ?>
<?php echo $this->headScript()->appendFile("/scripts/main.js") ?>

    output:

    <script src="/scripts/global.js" type="text/javascript"></script>
<script src="/scripts/global.js" type="text/javascript"></script>
<script src="/scripts/main.js" type="text/javascript"></script>

Reason:

  • Echo will output all elements in a placeholder.

Solution:

  • Echo only once for each placeholder.
  • e.g.: 
    <?php $this->headLink()->appendStylesheet('/styles/global.css') ?>
<?php $this->headLink()->appendStylesheet('/styles/main.css') ?>
<?php echo $this->headLink() ?>

<?php $this->headScript()->appendFile("/scripts/global.js") ?>
<?php $this->headScript()->appendFile("/scripts/main.js") ?>
<?php echo $this->headScript() ?>

Double/Multiple execute of bootstrap

Issue:

  • bootstrap is being executed twice.
  • specified action is being called twice.
  • counter increased twice per hit.

Reason:

  • Web browser loads a file which is not exist, either through src or href attribute with invalid or empty value (e.g. favicon.ico, global.css, & etc.), web server treats it as “Page not found” error (404).
  • Default configuration for Zend application, the default application (index.php) will handle error 404, an error message “Invalid controller specified” will be displayed, indirectly causing code in bootstrap.php also being executed.

Solution:

  • Create a favicon.ico in DocumentRoot. and
  • Prevent loading any file which is not exist. or
  • Modify web server configuration (httpd.conf or .htaccess),
    rewrite rule to exclude paths for specified file type.

    RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} (.*).(woff|ttf|svg|js|ico|gif|jpg|png|css|htc|xml|txt|swf)$
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]

It is not safe to rely on the system’s timezone settings

Issue:

  • Warning: date() [function.date]: It is not safe to rely on the system’s timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected ‘UTC’ for ‘8.0/no DST’ instead in ___.php on line ___
  • Warning: strtotime() [function.strtotime]: It is not safe to rely on the system’s timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected ‘UTC’ for ‘8.0/no DST’ instead in ___.php on line ___
  • ERROR: date.timezone not set in php.ini.

Reason:

  • Timezone must be defined for PHP.

Solution:

  • set timezone within your php code 
    date_default_timezone_set("___");

    or

    set timezone in your application php.ini

    date.timezone = "___"

Hello, Google Chrome World! Log for my first Google Chrome extension test.

Google Chrome now has extensions, and GG now want to have create some Google Chrome extensions ^^

By referring to the Getting Started tutorial and samples on Google Code Labs, I’ve created my first Google Chrome “Hello, World!” extension. It was much easier than expected.

Steps:

  1. Create a folder called mygc_ext01.
  2. Create a text file called manifest.json inside mygc_ext01 folder, contains code: 
    {
  "name": "My First Extension",
  "version": "1.0",
  "description": "The first extension that I made.",
  "browser_action": {
    "default_icon": "icon.png"
  },
  "permissions": [
    "http://api.flickr.com/"
  ]
}
  3. Prepare an PNG icon called icon.png put into the same folder.
    I’ve tested it with .ico file in my Windows 7, it works.
    If we use a .ico icon, we should also change the value for default_icon to our .ico filename (e.g. filename.ico).
  4. Now load the extension into Google Chrome.
    Click on Tools Google Chrome Tools menu and choose Extensions.
    Enable Developer Mode.
    Click Load unpacked extension…
    Browse for the mygc_ext01 folder, and press OK.
    My icon successfully displayed as an extension button on Google Chrome Google Chrome Extension.
  5. Edit manifest.json, add popup parameter below default_icon 
    ...
  "browser_action": {
    "default_icon": "icon.png",
    "popup": "mypage.html"
  },
...
  6. Create a new file called “mypage.html” put into the same folder.
    Display something in the html page body.
  7. On Google Chrome Extensions Developer Mode, press the Reload link behind My First Extension. And now if I click on my extension button, mypage.html will be displayed in a popup.

I’m planning to create some Google Chrome extension, but for now still need to sort my bunch of idea.

Below is an working example mygc_ext01 where mypage.html contains code to retrieve and display some picture from flickr.
