Default Media Query Sizes for Twitter Bootstrap

0

As someone who uses Twitter Bootstrap for front-end responsive development, I constantly have to look up bootstrap media query breakpoints. Some instances as an example are, when I need to use JavaScript for dynamic content manipulation such as events fired on window widths, or even adding some extra CSS classes to format content.

This keeps taking me to the bootstrap scaffolding guide to look for these values. So I thought I will document them in one place for easy reference.

You can find the different Bootstrap Breakpoints by version below.

Bootstrap 4 Media Query Breakpoints

Default mobile first breakpoints

// Extra small devices (portrait phones, less than 576px)
// No media query since this is the default in Bootstrap

// Anything below 576px - xs

// Small devices (landscape phones, 576px and up) - sm
@media (min-width: 576px) { ... }

// Medium devices (tablets, 768px and up) - md
@media (min-width: 768px) { ... }

// Large devices (desktops, 992px and up) - lg
@media (min-width: 992px) { ... }

// Extra large devices (large desktops, 1200px and up) - xl
@media (min-width: 1200px) { ... }

Mobile first SASS mixins

@include media-breakpoint-up(xs) { ... }
@include media-breakpoint-up(sm) { ... }
@include media-breakpoint-up(md) { ... }
@include media-breakpoint-up(lg) { ... }
@include media-breakpoint-up(xl) { ... }

Large display breakpoints

// Extra small devices (portrait phones, less than 576px)
@media (max-width: 575px) { ... }

// Small devices (landscape phones, less than 768px)
@media (max-width: 767px) { ... }

// Medium devices (tablets, less than 992px)
@media (max-width: 991px) { ... }

// Large devices (desktops, less than 1200px)
@media (max-width: 1199px) { ... }

// Extra large devices (large desktops)
// No media query since the extra-large breakpoint has no upper bound on its width

Large display SASS mixins

@include media-breakpoint-down(xs) { ... }
@include media-breakpoint-down(sm) { ... }
@include media-breakpoint-down(md) { ... }
@include media-breakpoint-down(lg) { ... }

WordPress AMP Automattic Plugin Enable for Custom Post Types(CPT)

0

wordpress_automatic_amp_earlIf you are on the band wagon to enable AMP on your WordPress website and are using the AMP Plugin by Automattic, you may realize that it does not work for custom post types right out of the gate. For this you need to make a small tweak by adding some modification to your theme or plugin code.

In the example below lets assume that your CPT is registered as ‘resources’ which we use as the first parameter of the function add_post_type_support() and you can change it to what ever your actual CPT is, duplicate that line with the new CPT names if you have multiple CPT’s. ‘cpt_enable_amp’ is passed to add_action() is just a function name and you can name it what ever you want as long as the function name below it is the same name and there is no other function named the same.


//If on a custom theme code would go in functions.php of the theme
add_action( 'init', 'te_cpt_enable_amp', 20 );

function te_cpt_enable_amp() {
    if ( ! defined( 'AMP_QUERY_VAR' ) ) {
        return; // do not add support if AMP plugin is not detected
    }
    add_post_type_support( 'resources', AMP_QUERY_VAR );
    add_post_type_support( 'news', AMP_QUERY_VAR ); // if you have another CPT called news
}

Once you are done with this, simply go to your front page URL for the post and add /amp or /?amp=1 the end of your URL. If you already have other parameters you may need to add &amp=1 and append it to the rest of the query string.

Domain Directing and Virtual Host Setup for WAMP Server

0

wamp_guy_leftearlAs with most developers who install WAMP you are probably working with localhost as your development domain name and directories for your projects.

For demonstration purposes lets say you are developing a WordPress or Joomla based site for Google where the domain is http://www.google.com

So you would typically create this directory structure where all your project files would reside, assuming Wamp is installed in the C Drive.

c:\wamp\www\google

 

Now you would be accessing this domain with the URL

http://localhost/google

 

And during your development life cycle all your links in the database and configuration will point to

http://localhost/google

 

This is not ideal when it comes time to migrate the site to the actual domain as now you will have to do some configuration and database maintenance to correct the links to point to the correct domain name.

So lets do it the right way.

Look in your Wamp installation directory and find the file named

httpd.conf

 

Scroll right to the bottom and you will see a couple of lines that look like

#IncludeOptional "c:/wamp/vhosts/*"
Include "c:/wamp/alias/*"

Uncomment the top line so it looks like making adjustments to reflect your Wamp installation path.

IncludeOptional "c:/wamp/vhosts/*"
Include "c:/wamp/alias/*"

Now find your Windows hosts. file which is generally located in

C:\Windows\System32\drivers\etc

You can try to directly open the file below in the text editor to save time trying to find it.

C:\Windows\System32\drivers\etc\hosts.

Once it is open the content will look something like this

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.
#	127.0.0.1       localhost
#	::1             localhost

Create a new line at the bottom with the line below without the hash(#) at the beging and save the file.

127.0.0.1 google.com

Now when ever you try to go to google.com your browser will look for the domain on your computer or localhost automatically, so if you need to access the actual domain just add the hash(#) in front and save or delete the line and save.

Next go to the follow directory

C:\wamp\vhosts

and open the file httpd-vhosts.conf for editing

For the sake of simplicity add this Apache directive towards the bottom of the file and save it, you can add extended parameters to the VirtualHost directive if you wish.

<VirtualHost *:80>
ServerName google.com
DocumentRoot "c:/wamp/www/google/"
</VirtualHost>

That’s it now restart Apache and enjoy development on your project with less hassle at the end.

wp_insert_post Consuming Large Amounts of Memory

0

wordpress_earl-150If you are using “wp_insert_post” to insert large amounts of posts from external scripts or even code within WordPress and notice “wp_insert_post memory consumption” is very high, “increasing PHP memory” may not be the solution you are looking for.

The reason for this is simply the fact that Wordpres Caches its queries and you need to prevent this from happening for the duration of execution of your code.

To accomplish this make the following two changes.

Add this line to your wp-config.php file

define( 'SAVEQUERIES', false );

This prevents WordPress from caching all the SQL Query’s and run-time results for the session.

Next add the following line in your script file, the location can be before the “wp_insert_post loop” or after you have defined WordPress.

wp_suspend_cache_addition(true);

This will prevent the result of each wp_insert_post from getting into the “Worpdress Object Cache” which is generally what consumes the memory.

Now you can insert millions of posts into WordPress without ever having to worry about memory issues.

[box type=”info”] For a internal scripts make sure you turn back wp_suspend_cache_addition(true); on once your inserts have been completed.[/box]

 

 

SOLVED Fatal error: Call to undefined function get_option()

0

wordpress_error_earl-150If you suddenly start to get the error “Fatal error: Call to undefined function get_option() in” “/wp-admin/admin.php” or “Fatal error: Call to undefined function wp() in” “/wp-blog-header.php on line %%” when trying to access the admin of your WordPress website chances are your WordPress installation has got corrupt.

Geneally it could be a few files that need replacing but its a good idea to replace the entire WordPress Core installation.

At this point you will need to identify the WordPress version installed and then download the same version from https://wordpress.org/download/release-archive/ then just overwrite the existing installation files with the contents of the file you download.

To find the version of WordPress installed you can generally go to the front page of your site(which should be working) and view the source. Then search and find the line that looks like
<meta name="generator" content="WordPress 4.0.4" />

In this example the version is 4.0.4

Export or Backup All MySQL Databases From The Command Line

0

Exporting or Backing up all MySQL Databases is a very common task you will need to accomplish at some point in your development experience.

MySQL provides a very handy Command Line tool called mysqldump (pronounced MySQL Dump) which does exactly that.

Some general reasons would be:
Performing periodic MySQL Database Backups.
Moving MySQL databases from one server to another.
Innodb or other DB engine maintenance.

Backing up all MySQL Databases into one .SQL

Running this command is both the same for Linux as well as Windows and we assume that you are on the same server(locahost), if you are connecting to another server you can specify the server hostname or IP by also specifying the “-h hostname” parameter.

mysqldump -u username -p --databases > databases.sql

While it is not generally recommended, some people also like specifying the password in the command line.

mysqldump -u username -p password --databases > databases.sql
Linux Specific Commands

If you would also like to gzip compress the file in one go then you can run the following command on linux.

mysqldump -u username -p password --databases | gzip > databases.sql.gz

Linux: ZIP Multiple Directories Into Individual Files

0

earllinux-150If you have been trying to ZIP multiple directories into individual files, this simple command will do just that for you.

ZIP Without Sub directories

for dirname in */; do zip "${dirname%/}.zip" "$dirname"; done

ZIP With Sub directories

Specifying the -r parameter to the zip program it will also include any sub directories of the individual directories that you are creating the individual zip files for.


for dirname in */; do zip -r "${dirname%/}.zip" "$dirname"; done

WHMCS SQL Helper Functions

0

Wondering how to access your WHMCS database while developing templates, custom pages or addon modules? well dont look any further. WHMCS  offers a full array of SQL Helper Functions to SELECT, INSERT and UPDATE information right form within WHMCS itself.

Do I have to create a database connection?

WHMCS maintains a connection to the database throughout each user interaction which enables you to leverage and utilize this same connection using the  provided SQL Helper Functions.

Lets dive in and take a look at what is available

FULL QUERIES

full_query(your query here)

While the functions below allow the ability to Query, Insert and Update the database, they are quite limited if you want to create complex queries. For this reason WHMCS offers the full_query() function where you have the ability to provide any SQL query to be executed.

It is important to note that there is no sanitation or sanity checking of the data. You will need to sanitize the data before hand when using this function to avoid possible SQL Injections or other errors.

This function is generally overlooked and missed which is why I have added it as the first function on the list.

SELECT QUERIES

select_query($table,$fields,$where,$sort,$sortorder,$limits,$join)

 

A select query is run as follows, with anything after the $where variable being optional. The $table should be the table name, $fields a comma separated list of fields to select, the $where var should be an array of criteria, $sort can be a field name to order by, $sortorder either ASC or DESC, $limits a range to select eg “0,1” “10,20” etc… and finally $join can be used for performing an inner join with another table.

INSERT QUERIES
