Protect files and folders from being deleted

Just to make sure we’re on the same page, I’m going to give these instructions from the beginning (also to help future visitors).  To get to the true heart of the permissions, you have to click though a bunch of steps.  My only guess is that this is to scare away the faint of heart, lol.

  1. Right-click the folder you want to protect (I’m using c:\users\chris\pictures) and choose Properties.
  2. On the Security tab, click Advanced.  The ‘Advanced Security Settings for Pictures’ dialog options.
  3. Click the Change Permissions… button.
  4. Click the Add… button, and type “everyone” (no quotes) into the box, then click OK.  A ‘Permission Entry’ dialog appears.
  5. Scroll to the bottom.  Place a checkmark in the ‘Deny’ column for “Delete”.  Do not add any other checkmarks.

  6. Turn on (checkmark) the option at the bottom called ‘Apply these permissions to objects and/or containers within this container only’, then click OK.  You should be back at a screen that looks something like this.

  7. Turn on (checkmark) the option at the bottom called ‘Replace all child object permissions with inheritable permissions from this object’, then click OK.
  8. Windows will set the deny permission on every file and subfolder under this folder, unless you have set up one to not inherit permissions from its parent (you probably haven’t done that).
Note: Deny permissions take precedence over allow permissions, so no one will be able to delete any file until/unless this permission item is removed.  This will block other apps from being able to delete either (for example, the Photo Gallery or Media Center).

Magento CE 2.0.0 – Step 1: Readiness Check

PHP Settings Check
Your PHP Version is 5.6.15, but always_populate_raw_post_data = 0. $HTTP_RAW_POST_DATA is deprecated from PHP 5.6 onwards and will be removed in PHP 7.0. This will stop the installer from running. Please open your php.ini file and set always_populate_raw_post_data to -1. If you need more help please call your hosting provider.

There are two solutions to this error:

  1. In php.ini,  add always_populate_raw_post_data = -1
  2. or in .htaccess, add php_value always_populate_raw_post_data -1 under <IfModule mod_php5.c>

How to exclude Alaska and Hawaii from US Free Shipping in Magento?

You will want to use the Table Based Shipping module for this. Go into System > Configuration and change Current Configuration Scope: to Main Website (the drop-down in the upper left corner). Then in the Shipping Methods screen, export the file. Then you edit that with all the states (minus Hawaii) with a minimum amount and then reupload the file and you are good to go.

You may follow these simple instructions:

Disable update checking of WordPress

When you designing a website for client with WordPress, you may not want your client click the “Upgrade” button for any reasons (mostly, by curiosity). We all know that it may cause unusable of customized theme. Here’s how to disable it. Open functions.php of your theme and add following lines.

add_filter('pre_site_transient_update_core', create_function('$a', "return null;"));

Including latest jQuery Library to your WordPress Site

First off, the basic code. This would go into your header.php. I put it directly above the

<?php wp_head(); ?>

call. If you don’t have that in your theme, you have bigger issues, as it is vital. Check out the info on that. The code looks like this:

wp_register_script('jquery', '');

That’s it really. That’ll deregister WordPress’ jquery and start using Google’s.

Use Module Title as link in Joomla 2.5

  1. Open your module .xml file example – modules/mod_articles_news/mod_articles_news.xml
  2. Add the following line between the first set of <fieldset name=”basic”></fieldset> tags
    <field name="title_link" type="text" default="" label="Title link" description="" />
  3. Save your XML file.
  4.  Now go to templates/system/html/modules.php open it & find the xhtml function or find this line “xhtml (divs and font headder tags)” here you can find this functionfunction modChrome_xhtml($module, &$params, &$attribs)
    if (!empty ($module->content)) : ?>
    <div class="moduletable<?php echo htmlspecialchars($params->get('moduleclass_sfx')); ?>">
    <?php if ($module->showtitle != 0) : ?>
    <h3><?php echo $module->title; ?></h3>
    <?php endif; ?>
    <?php echo $module->content; ?>
    <?php endif;
    & replace with
    function modChrome_xhtml($module, &$params, &$attribs)
    if (!empty ($module->content)) : ?>
    <div class="moduletable<?php echo htmlspecialchars($params->get('moduleclass_sfx')); ?>">
    <?php if ($module->showtitle != 0) : ?>
    <?php $title_link = $params->get('title_link'); ?>
    <h3><?php if($title_link) { ?> <a href="<?php echo $params->get('title_link'); ?>"> <?php } ?><?php echo $module->title; ?><?php if($title_link) { ?></a><?php } ?></h3>
    <?php endif; ?>
    <?php echo $module->content; ?>
    <?php endif;
  5.  Now you have link area in your module basic parameter add your link 🙂
