Child theme functions.php do I use php open and close tags?
I setup a child theme which works fine. It's importing the main style.css and has custom css styles along with custom header.php and footer.php files
When using functions.php in a child theme it's going to append the child themes functions.php to the main theme. Do I need to wrap my functions in opening and closing php tags or can I just add the following without php tags `add_image_size( 'related-thumbnail', 130, 130, true );` | Opening tags are required, closing tags are only needed if you have other code (HTML, CSS) after them in the same file. See PHP manual.
A closing tag with nothing after it may lead to problems with included files if they contain a BOM. That’s one of the reasons why all optional closing tags were removed for WordPress 3.4 in core files. Follow this style. It’s useful.
Here is an example from Automattic’s _s theme’s `functions.php`. | stackexchange-wordpress | {

How to remove Tags: text from the_tags?
The function `the_tags();` gives output as: `Tags: tag1, tag2`. But I want to get the tags only without the text `Tags:`. How can I use the function so that it does not out the text`? Thanks. | Use something like `<?php the_tags('', ', ', '<br />'); ?>`
From Wordpress codex for the_tags():
<?php the_tags( $before, $sep, $after ); ?>
> **Parameters**
>
> **$before** (string) Text to display before the actual tags are displayed. Defaults to Tags:
>
> **$sep** (string) Text or character to display between each tag link. The default is a comma (,) between each tag.
>
> **$after** (string) Text to display after the last tag. The default is to display nothing. | stackexchange-wordpress | {

How to display subcategory articles in the category view?
I have the wordpress category widget installed on my website that lists all categories/subcategories on my site and their hierachy:
Watch Accessories (1)
- Straps (1)
Watch Glossary (5)
Watch Guides (1)
- Maintenance (1)
Watch News (2)
- New Releases (2)
Watch Reviews (7)
- Christopher Ward (1)
- Hamilton (1)
- Seiko (2)
- Tissot (2)
- Vostok (1)
I am using the following permalink structure:
/%category%/%postname%/
When I click on the parent categories
>
>
>
it shows the category view and lists all articles in that category.
But when I click on a subcategory
>
>
>
it doesn't show the category view, it doesn't list all the articles in the subcategory. Instead it redirects to the first article in the sub category.
How can I get Wordpress to display all articles in a subcategory? | This is a matter of your template. To display the subcategories in a list view as well you would have to customize the template. I do not know what kind of template you use and how the file is named which displays the subcategories, but you could change it so that it displays the articles of the current category. Therefore you will have to take a look at the wp loop.
Another option would be to look for a theme that does so.
And there are plugins to display Articles on posts, but therefore you would have to implement the category pages manually. | stackexchange-wordpress | {

Fetching ten ten records from JSON API in word press

Youtube parameters within WordPress embed code?
Ok, so I want to embed youtube videos but also remove the annoying annotations. The following code works great from to embed the video
[embed width="599" height="360"]youtube.com/watch?v=mNf0v2WkV0U [/embed]

$('object').each(function(){
var $param = $(this).children(':first-child');
var newUrl = $param.attr('value') + '&iv_load_policy=3';
$param.attr('value', newUrl);
});

Thanks in advance. | Managed to do it,
<iframe frameBorder="0" probably_logged_in="0" width="599" height="360" src="youtube.com/embed/…; frameBorder="0">

Show recent posts from one category on a non-WP site
I'm trying to move back to WP for our blog, after struggling with a clunky CMS for a few years, but we'll be sticking with that CMS for the rest of the site. Is there a plugin (or code) that I can use to pull the recent posts in a particular category from my WP blog to the sidebar of my non-WP site? Assume full permissions on both the WP blog and the external site. | The easy way is to just use a PHP based reader and parse/output the results. Maybe your CMS already has one but if not and it's based on PHP you can use,
* MagpieRSS
* SimplePie
* Simplexml
Then you simple point it to your categories /feed, like --> `www.example.com/your_category/feed`
You can easily customize a feed to show whatever you want <
That way you can have a feed that only shows recent posts from one category using WP Query, you just have to point your reader to it.
Alternatives you can try via a plugin that allow for external HTTP requests:

Changing the username character limit from four to less characters
I want to create a user account on my multi-site installation of Wordpress with a username less than 4 characters. But since Wordpress has a limit of usernames at least being 4 characters, this error message is shown:

Stop editor from removing <p> tags and replacing them with nbsp
When I enter content in posts/pages' WYSIWYG editor, I do not get `<p>` when ending paragraphs, just ` `s. If I manually place `<p></p>` in the HTML mode, they are stripped as soon as I switch to 'visual' mode. This is repeated in several sites (I thought it was the theme but it isn't).
I have read dozens of topics and answers, but none solve my problem. I tried `add/remove wpautop` in my functions.php file but nothing helps.
I do not want to use a tinymce plugin. | I have done extended research and found the answer - I am now using a hook on 'tiny_mce_before_init'.
Based on other answers (special thanks to answer #2 @Chip Bennett), I have used the following code in my functions.php to secure the paragraph breaks (in the editor HTML mode they show as **& nbsp** but become paragraphs on the front-end):
function tinymce_config_59772( $init ) {
// Don't remove line breaks
$init['remove_linebreaks'] = false;
// Convert newline characters to BR tags
$init['convert_newlines_to_brs'] = true;
// Do not remove redundant BR tags
$init['remove_redundant_brs'] = false;
// Pass $init back to WordPress
return $init;

Using "/blog" as a site with Wordpress Multi-Site
I have Wordpress installed in the root directory, and plan to use the `domain.tld` as a portfolio and `domain.tld/blog` as personal blog site.
Since the `blog` keyword is reserved in Wordpress and can't be used for creating any child site, I tried changing the reserved words defined with `subdirectory_reserved_names` in `/wp-admin/network/site-new.php`. I was successful in creating /blog site. But the problem is, when I try to visit the `domain.tld/blog`, the error below is shown:
> This is somewhat embarrassing, isn’t it?
>
> It seems we can’t find what you’re looking for. Perhaps searching, or one of the links below, can help.
This only happens when I try to visit the child site's homepage, but the pages and posts are fine. For example, I can visit the `domain.tld/blog/about/` page, but can't do the same with `domain.tld/blog`
What is the problem here? And how can I solve it? | the main problem is that you should never alter core files ... the next time WordPress does an update it might overwrite the file you just changed.
you should not have needed to use a multisite for your scenario - you can have a portfolio and blog in the same setup using plugins or a great theme (even without using something called custom post types).
I'm not certain of a fix but have a look at this and contact @Ipstenu or @AndreaR on the Multisite forum for why you shouldn't do this

Does WordPress have an Browser Agent?
I want to block a directory to everyone but WordPress's internal upgrade feature (I am trying to get WordPress to do auto-updates of my premium plugin).

Anyone know what WP's internal User Agent is? | The WordPress user agent is set in the class `WP_Http` as
'WordPress/' . $wp_version . '; ' . get_bloginfo( 'url' )

function wpse_59788_user_agent()
{
// to remove this filter immediately uncomment the following line
// remove_filter( current_filter(), __FUNCTION__ );
return 'alfgjlkgjlkgjsldkjhrkjh';
}

add_filter( 'upgrader_pre_install', 'wpse_59788_register' );
function wpse_59788_register( $dummy )
{
add_filter( 'http_headers_useragent', 'wpse_59788_user_agent' );

How to disable tinyMCE button added by a plugin?

How to get all events from 'All in one Events calender' plugin in JSON format?
I am using `All in one Events Calendar` plugin to add the events. It works fine in CMS. I would like to display the events data in mobile version. for this i used `JSON-API` for obtaining web-services in json format.
To obtain all events , I dint find any plugin which will full-fill my requirement. so i started writing php code and uploaded the `getevents.php` to `www/.../services/getevents.php`
When i execute the file it is redirected to Calendar page in my cms. But i am expecting a json formatted output of all the events.
Please suggest a solution...
Thanks | I had to do the same thing. I used the JSON API plugin and had to create a new controller for JSON API that read the specific data out of the tables that All-in-One created.
Unfortunately there really were not the right calls in the calendar plugin to access all the data (or at least on the older version I used this for) so I had to write the whole controller to do it.
It took only a few hours to do and was pretty trivial once you look at the database structure, so this would be my recommended method to do this. | stackexchange-wordpress | {

blank white page in admin, white space hunting?
Upon logging into the dashboard, I am presented with a blank white page, tho the front end of the site works fine. I am pretty sure its due to a white space oposed to a plugin issue, but not sure where the white space could be hiding, I have checked wp-config and functions to no avail, any way to sniff them out?
Thanks! | What your seeing is probably a PHP fatal error, however your server will be configured to log them to the error log rather than present it on the frontend.
To find out what the error is, check your error log, or alternatively, if you don't have access to the error log or enabling the error log is not an option, you could enable printing the errors to the frontend. This will give you a blank page but now there will be a PHP error message. You will not want to do this in a production environment, and you won't want to enable this for very long if you're forced into that situation.
One way of doing this is by enabling WP_DEBUG in wp-config.php. How you would enable error logging to the screen is a subject for another question | stackexchange-wordpress | {

WordPress.org how to force expire Cached Banner-772x250 from my Plugin page
I created and added a banner to my plugin page < but there was a spelling mistake so I deleted & committed a new verison.
After I added the new image back in the SVN - it's still showing the old one. So I know that the CDN has cached the image for a very long time. I checked via anonymouse.org just now and the correct banner is showing.
**EDIT** It's been three days so far since I uploaded the image and for me I'm still seeing the same broken banner. I guess the CDN is serving out the old cached image to my IP :(
So my questions ...
* is there a way for _developers_ to expire the old image? or force it from the cache?
* does anyone know how long these banner images are cached for?
and ...
* Let me know if you are not seeing this image as I've got an update ready but not going to change /trunk until the correct banner is showing for everyone.

function my_approve_comment_callback($new_status, $old_status, $comment) {

How can I stop WordPress from catching URL's for static pages that I save on my server
I posted a question about whether it's possible to add a Page in WordPress without headers and footers.
Here's that question: Add a Page without header and menus?
So how can I create a static page with none of the WordPress stuff that appears on all the other pages of my WordPress site, and add html at that url?
How would I do that? | Richard
To be honest I think you are asking `How can I stop WordPress from responding to URL's for static pages that I save in other directories on my server`
Basically its in 2 files
* your VHOST (which maps mydomain.com to www/some_folder/ )
* your .htaccess file which manages redirects
So you can do 2 things ...
1\. get a new VHOST for subdomain so something-mydomain.com maps to another a folder on your server - or -
2\. update your .htaccess file to include redirect urls
your .htaccess file will pick up any requests for urls BEFORE WordPress gets involved.
so you can have `mydomain.com` and WordPress will manage all requests and then create a rule that says `mydomain.com/this_page.html` is in `www/some_folder/this_page.html`
here is an example of code for a redirect to a static page that you can add to your .htaccess file:
#static page redirects here
redirectMatch 301 ^/this_page(.*)$ /this_folder/this_page.htm' | stackexchange-wordpress | {

How to check for images before echo
I have the following code in attempt to check for an image before an echo. The reason for doing so is if there is no image it won't echo anything and there won't be a missing image link put in a post that has no image. However this code does not work and when no image exists a missing image icon is added. Is there another way to solve this.
<?php $image = wp_get_attachment_image_src(get_field('post_image1'), 'thumbnail'); ?>
<img src="<?php if($image !=false) echo $image[0]; ?>" alt="<?php get_the_title(get_field('post_image1')) ?>" />

Custom Fields on User Dashboard?
I was thinking about either getting a plugin or shortcode to create custom field that shows on user and allows admin to change them and edit the information, not users.
For example, if we have wp site where 5 members are registered under admin and there are tasks that admin wants to show in their profile page. so there has to be non editable text area. so that member can view the task if they are logged in. It could show either on dashboard page or any other specific non editable widget.
Is it possible? any pointers for this particular task? links? | I just found this plugin which allows you to create custom options <
You can then place the php code to display the value of the option inside your dashboard for members who are logged in but not administrators. You can display the value as text wrapped in a div tag and style as you need.
Using the plugin I have linked to you can create two options one called 'members' another called 'guests', now that you have control of these variable values through your dashboard as the administrator the code below should display these messages accordingly to your members if they are logged in or not logged in.
An example php function may look like this
<?php
if ( is_user_logged_in() ) {
echo get_custom('members');
} else {
echo get_custom('guests');

How to add "time" data this?

we can display in sidebar like MOST POPULAR POSTS OF THE **DAY** , **MONTH** or **HOURS** (if possible)
here is my sidebar code
<?php query_posts('meta_key=post_views_count&orderby=meta_value_num&posts_per_page=4&order=DESC'); if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<?php echo getPostViews(get_the_ID()); ?>
<a class="tab_caption" href="<?php the_permalink(); ?>" title="<?php echo $post_title; ?>"><?php echo get_the_title($post->ID);?></a>
<?php endwhile; ?>
<?php endif; ?>
<?php wp_reset_query(); ?> | Well, the code you are using to count views does store the count data as a `custom_field` value. If I want the functionality you mentioned in question, I'd rather use a custom plugin to create a separate table in database to store view count and respective dates.

Changing wp-content to other name? Multisite set up
Is there an easy way to change the words `wp-content` that show in the source code to `xyz-content` without breaking my site?
I want to do it for branding purposes.
I tried:
1. Url rewriting but the original `wp-content` still shows in the source code.
2. Doing a site download, find and replace and then re-upload but it takes over 24 hours with my server.
3. The plugin Real-Time Find and Replace changes the words from `wp-content` to `xyz-content` quickly, but the css etc does not load.
Is there another way to do this? | You can move the wp-content directory to a different location, which essentially renames it.
First, in your wp-config.php file, add this:
`define( 'WP_CONTENT_DIR', $_SERVER['DOCUMENT_ROOT'] . '/folder/path/to/new/dir' );`
And second, also in wp-config.php, add this:
`define( 'WP_CONTENT_URL', '

Where to put snarfer.php?
I followed these instructions: <
My understanding of those instructions was that the file snarfer.php needed to be in the folder 'themes', so it appears in the same list as the following folders and file:
twentyeleven (folder) twentyeleven-child (folder) twentyten (folder) index.php
…but when I put it there, and went to create a Page, the new template didn't appear as an option in the list Default Template / Showcase Template / Sidebar Template.
So I tried putting snarfer.php in the folder 'twentyeleven-child' -- which is the active theme.
And the new template now appears in the Template list when I create a Page.

When I create some text in a test page and apply the template I created using the instructions at that link, the text I create doesn't show up when I go 'view page'.

* Make sure the image is of either `.png` or `.jpg` type.
* The `.gif` images are not allowed.
* It may take upto 15 minitues to appear on your plugin page.

WordPress multi-site: How do I create the home page, the root URL?
I have a WordPress installation running since ages ago at mydomain.com. It's mostly administered by someone else, so I haven't really had to understand the inner workings of WordPress—I can create and edit content, but I don't mess around in the code.
Today I created a new site using the multi-site features, located at mydomain.com/project/. Everything went well—the site was created, I could set up the theme etc, but when I try to create the home page (i.e. simply mydomain.com/project), I can't get the URL right. No matter how I try, I'm not allowed to create a page with an empty slug, so all pages I create get something like mydomain.com/project/some-slug instead.
How do I create a page with the URL mydomain.com/project in this site? | You can set your homepage in Wordpress by creating your page (the slug doesn't matter) and then going into `Settings` > `Reading` and selecting the page in `Front page displays` > `Front Page` setting. | stackexchange-wordpress | {

Images inside post title
Is there a way to insert images into a post title? It would also need to display the alt text in the `<title>` tag, permalinks, etc.
The reason I need to do this is I have a client who want their logo used in page titles instead of plain text. Therefore, the image could be anywhere in the title, so I can't just append/prepend the image.
The only solution I can think of would be to do a find and replace using javascript, but this doesn't seem like a great solution... | A search and replace solution does sound viable. I wouldn’t do it via JavaScript, though.
add_filter('the_title', 'wpse60174_logo_in_title', 10, 2);

{
// Add a <span> around the company name
return preg_replace('~\bCompany\s+Name\b~i', '<span class="company">$0</span>', $title);
}
With the extra span in place it is just a matter of applying some custom styles to it. You can provide different styles depending on where the title is shown. You may even decide to not replace the company name with a logo image in some place. It’s a flexible setup with clean HTML.
/* A demo CSS rule */

wp_query() get_col error

Original answer that didn't solve the issue but might be interesting for others some day.
Here's an alternate way that avoids having to directly query the DB. You'd replace all of your code up to and including the `$res = ...` line:

$search_query = mysql_escape_string($_POST['value']);
// args for get_posts
$my_post_args = array( 's' => $search_query, 'fields' => 'ids' );
// get array of post IDs (see "fields" argument above)
$my_post_ids = get_posts( $my_post_args );
// now WP_Query args
$res_args = array( 'post__in=' . $my_post_ids );
// make sure that the args parameter matches (it doesn't in your code snippet)

Is it possible to host a WordPress site entirely on Cloudfront?
I love the Cloudfront approach described here: <
I wonder if this is possible to do with caching plugins that create static html files? | It depends what you mean, **entirely on Cloudfront**.
Cloudfront is a CDN only. It can't run any server side scripting environments (PHP or MySQL), it therefore isn't possible to host a wordpress site entirely with Cloudfront.
You could alternatively use Cloudfront to host your images to improve speed. The closest way to host a wordpress site _entirely_ on Cloudfront is to use ‘ **Origin Pull** ’.

New Template -- copy existing template and change code?

> Correct process for a new Page Template?
I created a page template following these instructions: <
I'm having difficulty figuring out how to apply margins, fonts, and font sizes to the new page template.
So I'm thinking perhaps there's another way to do it: if I can make the new template so it displays Pages exactly the same as my active template (twentyeleven-child), I can then remove things and change things -- I might find it easier this way to locate the things to remove and change rather than figure out how to build the Page Template from scratch.
Is this a sensible approach?
If it is, would I copy all the text in content.php to my new page template file, and then edit things both in the new page template file and in style.css ? | For custom templates, I tend to use the default `page.php`, make any changes to the HTML (if need be), and enqueue an overriding stylesheet before `get_header()`:

Using WPDB to output raw XML fails because of wp-blog-header.php
I'm coding a plugin. One particular file of this plugin is supposed to pull data from the plugin's custom DB table, and output it with minimal processing as raw XML.
The problem is, to get the WPDB class to work when the file was opened directly, I had to add a require to wp-blog-header.php. This worked great BUT it turns out that including the file outputs the tags < html>, < head>, and < body>, which kinda screws up certain parts of the XML.
Is there any way I can [A] Suppress the tag-spitting behavior of wp-blog-header.php? [B] Get WPDB working in some other way?
Or should I just not use WPDB for DB access in this file in the plugin?

how to create several url aliases for a page
on the root page of a WordPress site we have a custom page template, that also handles some forms and dynamically changes part of the content.
Something like this:
<form action="" method="post">
...
<input type="hidden" name="action" id="action" value="do_this" />
</form>
and then in the page template we check for $_POST['action']=="do_this". Works perfectly.
Now we would like that when these forms are posted to have the url change (action="/do_this").
For that to work, we need /do_this to deliver the root page, but the url to not change.
we have tried this in .htaccess
RewriteRule ^do_this(.*)$ index.php?p=12 [L]
but it changes the browser url.
It must have something with WordPress, since if we use another file
RewriteRule ^do_this(.*)$ test.html [L]
it works: the url is not changed and the test.html is being delivered.

I have a WordPress theme built with Masonry script , I added a new template file for list gallery, is working ok in FF and IE but in Google Chrome gallery images (inside containers) are overlapped.
Seems like the content is loading faster than images but they don't adjust afterwards. | I can't find any reference about it but it seems Google Chrome (v 21.0.1180.60) do need specified image sizes, in image tag or passing this in css (either class or local):
style="display:block;width:333px;height:333px"
Or:
container.img { display:block;width:333px;height:333px }
Maybe this issue has something to do with this question, but I'm not sure.
They say images need width and height info in image tag, but some themes/plugins around aren't even informing `alt` tag. | stackexchange-wordpress | {

Can I get the ID of an inserted / linked image?
I am using this code to get the url of first inserted image in a post. Is there any way I can get the ID of that image.
global $post, $posts;
$first_img = '';
ob_start();
ob_end_clean();
$output = preg_match_all('/<img.+src=\'"[\'"].*>/i', $post->post_content, $matches);
$first_image = $matches [1] [0]; | No, an image placed inside a post/page content don't reference in your database other than inside your content only.
That's why an image attached is better: you have full control over your images since they are in your server and referenced in your database. An attachment is a child post, once you attach an file to a post/page you can use get_children for retrieve file description, title etc. | stackexchange-wordpress | {

How should I structure my post types?
For the site I am making, I have a few post types: News, Events, Projects, Placements. Each one of these post types will need its own archive page, accessible through the navigation. I am able to create these post types using the Types plugin, but my question is how do I create a archive page for them? I can't figure out what the URL will be. `/projects` for the post type with slug `projects` gives me nothing.
I think I understand how the templates for custom post types work (`archive-{post-slug}.php`), but I don't know how to make these pages accessible. | When a post type is registered, you need to at least set `has_archive` to true. This will use the post type name as the slug for archive. You can also specify a string representing the slug for `has_archive`:
'has_archive' => 'projects'
This should be accessible under Type's advanced settings, according to their documentation. | stackexchange-wordpress | {

Calling a div and content in php?
Is there a code that i can place in the header that will call a certain div and the content i place inside it for every custom post type i have, Somthething like this.
<?php if (is_post_type('pretty-little-liars') ) {echo '<div id="headerimg"><img src=" } ?>
I know that the code above doesn't work, but is there a way that i can call something like that for each post type i have, i will be placing this code in the header.
Also if anyone does have the solution could you please tell me where do i add a second line to the code that repeats the first line but with a different post type name? | I think that will only work in the loop, but what you can do outside of the loop is use
<?php
if (get_post_type() == 'pretty-little-liars') {

Contact Management Plugin suggestions, or tutorials/resources recommendations
I will soon be building a site for a local Non-Profit Art Community, and they would like a to have a powerful **contact/member management system** that can do these key things:
1. Store User Contact info (Address, Phone, Email, Website, regdate, etc.)
2. Synchronize with a newsletter mailing service, their preference is Emma. (Alternatively, the desired plugin could handle the newsletters internally)
3. Tag users with multiple tags, example would be Artist, Volunteer, Member.
4. Track membership and expiry, as well as payment history for Members.
5. Hopefully use the built-in Wordpress User area of the admin.
My question is, can anyone recommend a plugin that can get me all the way, or part of the way there? | Buddypress will probably help you too. I guess you'll want your community members to interact?
Also just search the wordpress.org plugins repository, for "membership" or "members" plugins to compare with.

How to rate a post from Admin Side / Manually?
I am working on a Mini Job Site.

Best rated people will be on top. so visitor'll get better choice.
visitor are not allowed to rate posts
like this
!please have a look
how to do this ?
{1} Meta-box uses {2} Custom Field
help me please | Here's something I'd use if I want to do that without using plugins
Create a custom field as `rating` and provide the value while doing post. Suppose I gave a rating of 6, Now wordpress save it into the database as.
* `meta_key` => rating
* `meta_value` => 6
Now to show the rating on post I'll use this code into `single.php` or `index.php` but make sure to put it within `Wordpress loop` \-
<?php
//grab the rating value
$rating = get_post_meta($post->ID, 'rating', true);
//prints star image
for ($i=1; $i<=$rating; $i++){
echo '<img src="LINK-TO-STAR-ICON"/>';
}
//prints unstar image
for ($i=$rating; $i<10; $i++){
echo '<img src="LINK-TO-UNSTAR-ICON"/>';
}
?>

Display "a generated one [avatar] based on their e-mail address"
I was looking at the discussion settings in WordPress and near the "Default Avatar" option I saw that it said the following:
> For users without a custom avatar of their own, you can either display a generic logo or a **generated one based on their e-mail address.**
(I bolded the second part.) I'm just curious as to how these avatars are "generated" based on email addresses. | The way gravatar works is that it creates an MD5 of the email address and passes that to gravatar.com. If an avatar exists for that hashed email address, then it gets returned.
If not, then it generates a random one based on the data in the hash. Essentially, it's arbitrary. There's code in there that basically says "if character 3 is A, use this color" and so forth. This means that the same email generates the same avatar every time, but still makes it randomish.

How do you keep your live and and testing server?
I have a live site and a testing server (XAMPP) that I built the site on originally before publishing it. Obviously, there are a number of things you need to do to migrate a site from one place to another. I was hoping to tap into collective experience to find out the best way of doing this, keeping fuss to a minimum.
The obvious answer (to me, at least) is to keep a folder of files to merge into the XAMPP files for when it's built on the testing site and a folder of the same files but with production server info to apply when the site is uploaded.
This is a bit messy and leads to mistakes. Is there a program out there that I've never come across or better way of doing this?
(I've been auto-warned about the subjectivity of this question, I do hope it passes the community test!) | there are quite a few threads on here about this topic ... just look at these examples:

Where do hackers usually run their hacking script?

Now my question is where do they usually run this? Do they run it inside the hacked server or their own PCs? | They run it on your server, just like any other script runs (including WordPress).
In the log you provided, it looks like the hacker knew your password. Perhaps you are using the same password on other sites, and he somehow gained access to one of them?

Any plugins that upload, resize, and display images?
Here is an ideal workflow for my situation:
1. Upload a folder full of images
2. Resize images according to a specified size
3. Have the ability to organize these images into folders (collection1, collection2, etc)
4. Display the images within these folders in a non-flash gallery (collection1 on page 1, collection2 on page 2, etc)
Is there any plugin that will help this process from start to finish, or set of plugins that play nicely together?
It's important that these galleries work on non-flash-supported devices, as mobile and tablet traffic will be significant.
Paid is fine for a good quality plugin. | i've been using nextgen gallery and i believe it fits your needs:
_1\. Upload a folder full of images_ : **yes**
_2\. Resize images according to a specified size_ : **yes** , on the gallery option you can set the standard size.
_3\. Have the ability to organize these images into folders (collection1, collection2, etc)_ : **yes** , they're called albums and galleries. Albums contain Galleries, and each Gallery can a set of images.
_4\. Display the images within these folders in a non-flash gallery (collection1 on page 1, collection2 on page 2, etc)_ : **yes** use the shortcode `[nggallery id="x"]`

Make wordpress comments work with include templatepath
How can I make the wordpress comments work with:
include(TEMPLATEPATH."/comments.php");
instead of:
comments_template( '', true );
Ay ideas? Ty | Short answer: you _can't_.
Longer answer:
You can _include_ `comments.php` as a _template-part_ file inside another template, via:
get_template_part( 'comments.php' )
...but that won't actually make comments _work_ , because the `comments_template()` template tag does far more than merely include the `comments.php` template-part file. In order to make comments actually _work_ when using `get_template_part()` as opposed to `comments_template()`, you'd need to duplicate all of the functions performed by `comments_template()`. And if you need to duplicate all of that code in order to make comments _work_ , you might as well just use the function itself. | stackexchange-wordpress | {

How to create directory using username within theme

echo "success";
} else {
echo "error";
}
}else{
echo"size_error";
}
?>

Does code run faster in functions.php than in different theme templates?
For example I have this code which gets the post title:
function baracuda_sinlge_post_title(){ // Single Post Title
$post_title = single_post_title('','0');
return $post_title;
}
Where do you think it would run faster, in functions.php or direcly in the template I need it to be like this:
$post_title = single_post_title('','0'); | It doesn't matter. I know you think it matters, but it doesn't. The reason it doesn't matter has nothing to do with which one is actually faster. The speed of your website will NEVER be influenced by the placement of this function. Theoretically, sure, but in practice you'll never see it. The only two places to spend time are the front end bandwidth and back end DB calls. That's it. The front end will be too heavy, have too many http requests, errors, and a plethora of other front end issues. And the database is typically the biggest bottleneck on a website.
If you're not spending time in these two areas, you're wasting time. | stackexchange-wordpress | {
