wp_get_attachment_image_src() with advanced custom fields returning empty
I am using the advanced custom fields plugin to upload images for an image gallery. I am attempting to retrieve the different sizes of images that are saved in the uploads folder and having problems.
$image = wp_get_attachment_image_src(get_sub_field('image'), 'full');
When I echo out the results of this I get nothing. I know that the images are being saved as different sizes because I can see them in the uploads folder and the get_sub_field('image') is returning the proper image src.
Is there anything else I need to do to get this to work? | What's in get_sub_field('image')? wp_get_attachment_image_src() parameter 1 should be the attachment id, not the attachment src, if that's what you have.
I use the following function to get an attachment ID from an image url as as far as I know WP doesn't have a method for this at present.
function get_attachment_id_from_src ($src) {
global $wpdb;
$reg = "/-[0-9]+x[0-9]+?.(jpg|jpeg|png|gif)$/i";
$src1 = preg_replace($reg,'',$src);
if($src1 != $src){
$ext = pathinfo($src, PATHINFO_EXTENSION);
$src = $src1 . '.' .$ext;
}
$query = "SELECT ID FROM {$wpdb->posts} WHERE guid='$src'";
$id = $wpdb->get_var($query);
return $id;

Permalinks without subdirectories

permalink_structure: /%postname%
This gives me URL like this on my pages:
1. #
2. #
3. #
But I want it to be:
1. #
2. #
3. #
How can I make this happen?
I still want to use the parent function in wordpress admin...
**The reasons why I want this are:**
* It looks so much better
* When I (or some one else) change URL of page1 I am not messing up the URL for page 2 and page3 (less 301 work)
* (Better SEO) | One solution would be to create all your pages as root pages and then use the Menu page in "Appearance -> Menus" to define the structure of the pages. This assumes that your theme supports Menus, which the default Wordpress themes TwentTen and TwentyEleven do.
**Update:**
Here's a couple of links that might help you do this without using the menus functionality (as I fully agree with your comment that it's a little annoying to use the menus functionality).

Updating seperate database when post attachment is changed
I have a seperate database with lists of users, brochures and brochure URL's, and timestamps of when a brochure was ordered, but I want my database to update everytime a brochure (PDF) attachment is updated in the admin back end of wordpress.
When a user requests a brochure they receive a reminder after a few days wiuth a link to the PDF they requested. I have most of it figured out I just need to know how this link can constantly link to the latest PDF of the brochure they requested.
Thanks :) | You can hook into `add_attachment` and/or `edit_attachment` actions and carry out an update on your separate database with the appropriate info. In both cases the attachment ID seems to be the only argument but you can easily `get_post` or `get_post_meta` if you need anything else.

Need help changing back the correct wordpress url

Changing WordPress sort order for returned child pages

Is there some CSS problem there? How can I detect/fix the problem?
Thank you. | Seems like the superfish menu plugin is not setting the CSS properties correctly when hovering over the menu item. You can fix this by updating the CSS in your styles.css file at line 155 from:
.nav2 li.sfHover ul, ul.nav2 li:hover ul {
background: none repeat scroll 0 0 #B3B3B3;
color: #FFFFFF;
text-decoration: none;
z-index: 1000;
}
to:
.nav2 li.sfHover ul, ul.nav2 li:hover ul {
background: none repeat scroll 0 0 #B3B3B3;
color: #FFFFFF;
text-decoration: none;
z-index: 1000;
visibility: visible!important;
display: block!important;
}

Getting the Posts' permalinks from XLMRPC
I'm new to WP and I must fetch pages/posts from a blog in another subdomain. I'm using ZF to do this. I've recently found out the `getPages` doesn't get me what I want (posts; duh!).

Can't seem to see images on my machine but can on the server
Hello I just started using wordpress (complete noob) but I need a bit of help. I have installed wordpress and on a linux/centos webserver and this works fine. However when I use another machine, open a web browser, type in the url, the site looks different from what it looks like on my server.

So I don't now what the problem
Just to let you know my wordpress url is localhost and my site url is also localhost if that may help. | "localhost" normally points to the webserver on the machine the request is made from.
You installed wordpress on your server to run under "localhost". So if you open a browser whilst on the server and go to "localhost" it will look for the site on the server and find it.
However, if you open a browser on your "dev machine" and go to "localhost" it will look for the site on your dev machine and it won't find it there as you installed it on the server.
Now, if you're connecting to the site using your server domain name (eg < then whilst that request will work, the links to the images and other posts will not work because Wordpress creates those links as " which your browser will look for on your local machine and not find there.
The best solution: Logon to the site from a browser on your server and change the URLs in the dashboard to your server's domain name and always use that domain name to connect to the site. | stackexchange-wordpress | {

Make jQuery library load before plugin files

Tumblr-like Post Types for WordPress

wp_nav_menu not appearing for a couple pages
_I solved the problem with the page, the correct answer is ptriek's comment below._
Well I'm having a bit of an odd problem here, wp_nav_menu works on all pages EXCEPT my category pages (probably my archive page too but there's no links on the website to the archive pages so that's alright).
Although there is archive.php in my theme files, this controls what is displayed on category, tag, archive, author, etc. pages.
I just don't understand why, since every page uses the same header.php to display wp_nav_menu, it won't show up for the category pages.

Remove unwanted part of permalink custom structure from CPT url?

disable defaault wordpress comments from a plugin
I am modifying the facebook comments plugin to my purposes. What I'd like to do is have it remove Wordpress native comments automatically if it is enabled- in fact what I'd really like it to do is use the Wordpress comments settings in the item itself and/or general settings to decide whether it should show or not.
Disqus works like this and its just how you would expect a comments replacement system to work by default- I think this plugin should work like that unless you tell it to do otherwise.
Does anyone have any ideas how disqus achieves this?
D | Most themes used `comments_template` to include their comment areas. It's completely full of filters, one of which is the include file (usually comments.php) that you can hijack to include a file from your plugin that contains all the stuff for facebook comments (or nothing if you just want to disable comments.
Example:
<?php
add_filter( 'comments_template', 'wpse35363_comments_template' );
function wpse35363_comments_template( $file )
{
return plugin_dir_url( __FILE__ ) . 'path/to/your/file.php';
}
As far as general settings and per post settings, those are stored in `wp_options` and `wp_postmeta` respectively. Take a look at how the default comments compat file looks and you should get an idea about how you can do this in your plugin. | stackexchange-wordpress | {

1. I can't find a command line tool that will reliably post. (I have shell access on the computer on which the wordpress site is running.)
2. I can't get the XML-RPC API to work. I get an error that I need to use the RPC via POST. I'm told that this is a result of dreamhost running an out-of-date PHP version, but I've tried to use the mods to wordpress and it hasn't been successful.
So is there an easy way (or even a hard way) to post to a wordpress blog?
Thanks. | Since you have shell access, you could use wp-cli:

How do I create a meta box for dates?
I am creating a custom events page and I want to know how to create a custom meta box to save event dates. I don't want it to be a regular meta box because I will be using this to make a custom search bar so I am guessing I have to save it to MySQL no?
I am lost, as to how I have to go about this. Any ideas?

How can I automatically attach posts to a map?
I'd like to display a Google map of places relating to posts (eg, places I've visited).
Is there a plugin or method available that will allow me to have a Google map on a page and when creating a post, I can put in an address or lat/long for the post, so that it automatically gets added to the map?
I'm thinking of something a bit like Drupal's Location module, which adds nodes with lat/longs to a main map. | You could use this plugin, although it may only be compatible to 3.2.1. And this plugin may help you out, although it seems a little complicated to implement a map for all the posts.
You could also use a custom field for lat/long on each post, and then create markers using wpdb calls, grabbing the post_meta data, and using the Google Maps API to place the markers, but it sounds as though you'd prefer an out-of-the-box solution.

How can I make the "Preview Post" button save and preview in the same window?
When you choose "Preview", which is actually a link,
<a class="preview button" href="?p=52&preview=true"

setTimeout(function(){
jQuery('.preview.button').unbind().removeAttr('target');

Simplify the admin end
I'm thinking about using WordPress as a content management system for a school. The frontend of WordPress itself would never be seen by the students, but the admin interface would be used by teachers to post bulletins and other messages and news items. Wordpress would then provide an RSS feed to integrate with the schools existing systems.
My question is how can the WordPress backend be simplified for use by people with very little technical knowledge. All the is really needed for most users is the ability to view previous posts, and write posts.
Can this be easily achieved using some themes or plugins? Or am I better off using another system for this, if so what?
Thanks. | First, once you assign users to the role of Author or Editor they will see quite a few fewer menu items (Settings and Appearance goes away) - see Roles and Capabilities. Try creating a second account for yourself and seeing if that helps.

I've done something very similar on other systems and it works fine if you take care to return the correct headers.

What is a good resource to find out about making custom walkers?

Email notification via WP_Mail on published custom post type

Alter the image used for a user who has not uploaded a custom image yet

!screenshot of images in comment section

Without installing plugins, is there a native WordPress setting which would let me upload a default image to use for this? | Here's a function you can put in your theme's functions.php file to force your own default avatar. Update the $myavatar line to point to your image path/name:
// Adds a new default avatar to the list in WordPress admin
add_filter( 'avatar_defaults', 'mytheme_addgravatar' );
function mytheme_addgravatar( $avatar_defaults ) {
$myavatar = get_bloginfo('stylesheet_directory') . '/images/my-avatar.gif';
$avatar_defaults[$myavatar] = 'New Default Gravatar';
return $avatar_defaults;
}
Once you've added this function, your new avatar will appear in the list in the WP control panel in the "Settings > Discussion" area. Select it and save. Now if visitors don't have their own Gravatar your new avatar will appear instead.
(If you're just looking for how to get your own Gravatar, which will show up on most WordPress blogs/sites in the comments section, go to < and sign up for a free account.)

MySQL query performed 4 times inside loop
I have enabled custom php in my pages through the use of the `exec-php` plugin so I can run more complex pages than the standard WordPress page. I have had no problems with this plugin so far.
I have recently moved a page I was using independently from WordPress to inside the WordPress system. Now instead of running a `INSERT` mysql query once like it should, it runs it 4 times leaving me with 3 redundant rows in my database.

Basically, you cannot guarantee that your code will only run once per page load, since several different things in the system may be processing your content, and thus executing your code, multiple times.
Instead of using Exec-PHP to store the code in the post content, create a Page Template which contains your code, then attach it to the Page in question.

$wpdb->flush(); breaks the loop

* I am using the `exec-php` plugin and consequently this page is entirely php
* I am also having another possibly related problem as detailed here | In the code you posted in your other question, your call to flush() is using the wrong variable: $wpdp->flush();.

Facebook profile pic used as avatar

If, however, you've referring to **CONTENT** changes then that's a different thing all together. eg If you edit a post on your dev site and want that post change to be applied to your live site, or if you've added and activated a plugin on your devsite. If this is what you want, I am sure there are solutions, but I would recommend you look at your workflow to see if this is necessary. | stackexchange-wordpress | {

How to query with get_posts() for posts with any tag
I need to do a simple post query that will get any post that has at least one tag. This is my current code that gets the posts with tag ID 27 or 36, but I need to modify it to get all posts with at least one tag.
$args = array(
'numberposts' => 5,
'tag__in' => array(27,36)
);
$myposts = get_posts( $args ); | You could try this.
$all_tags = get_tags();
$tag_id = array();
foreach( $all_tags as $tag ) {
$tag_id[] = $tag->term_id;
}
$args = array(
'numberposts' => 5,
'tag__in' => $tag_id
);
$myposts = get_posts( $args ); | stackexchange-wordpress | {

hook for dashboard show_user_profile
I'm looking a way to avoid regular users go to profile and dashboard page. Have this little code to work with profile page:
function lockdown_profile()
{
global $current_user;
return !current_user_can( 'manage_options' ) ? wp_redirect("/profile") : true;
}
add_action('show_user_profile', "lockdown_profile");
And works, but i need to do the same for dashboard page, any ideas? | `show_user_profile` is the wrong hook to use. You should redirect before anything gets sent to the browser (eg. before headers are sent).
Fortunately there are actions that happen much earlier: `load-{$pagename}` is the one you want. So you can hook into `load-index.php` and `load-profile.php` to throw people back to the front end.
<?php
add_action( 'load-profile.php', 'wpse35742_maybe_redirect' );
add_action( 'load-index.php', 'wpse35742_maybe_redirect' );
function wpse35742_maybe_redirect()
{
if( current_user_can( 'manage_options' ) ) return;
wp_redirect( home_url( '/profile' ), 302 );
exit();
}
All that said, you would be better off adding a new role that has even more limited capabilities than the typical subscribers: don't let them view the dashboard or their profiles (the `read` capability). | stackexchange-wordpress | {

Theming media inserts
When I Insert media into my post or page it's rendered as a normal link.
Would it be possible to somehow theme links that point to e.g. PDF or other file types? | I think the easiest way would be doing this with jQuery:

Get previously visited page ID
I would like to get the ID (or permalink) of the page the visitor visited just before visiting the current page - in other words the ID of the last page in the browser history.
Can this be done? Any idea how to do it? | Break this down into two parts:
First, we create a variable that stores that last-visited page URL, like this:
$prev_url = isset($_SERVER['HTTP_REFERER']) ? $_SERVER['HTTP_REFERER'] : '';
Then, you could either use substr and strpos to trim down everything between _?=_ and the _/_ after the ID number. like this:
$prev_url = '
$id_block = substr($prev_url, strpos($prev_url, "?p=")+1);
$id = substr($id_block, 0, strpos($id_block, "/"));
.. Or, you could use jQuery/Javascript to achieve the same.
I haven't tested this but it should work - let me know how it does! Good luck ;) | stackexchange-wordpress | {

When to use Wordpress loop or Foreach loop?
Under what circumstances would you, (should you?) use a foreach loop, instead of the wordpress loop.
I have no real coding need, but I'm curious. What's good practice here?
Should I:
$args=array(
'post_parent' => $pos_id,
);
$sublabels=get_posts($args);
foreach($sublabels as $sublabel) { // blabla something to do foreach}
Or:
query_posts(array(
'post_parent' => $pos_id,
'cat' => 'label',
));
while (have_posts()) : the_post() ?> // and then the blabla something for each
And why? | Your examples are showing two different thing The first one is looping over categories and the second is looping over posts, so the answer in this case is simple and depends on what you need to loop over (posts or categories).
No if you meant when should you use **`query_posts()`** vs. **`get_posts()`** vs. **`WP_Query`** then take a look at this **`awesome answer`** . | stackexchange-wordpress | {

Best function/method to access wp-config?
I have a developer who is accessing the wp-config file directly to get database information. I would think that WP has a better way to do this. What do you think community? | I am not aware of a Wordpress function to do this. But have a look at this search and replace tool:
<
This achieves what you want by reading in the wp-config file and scanning through it. Have a look at the function "icit_srdb_define_find" on line 374. | stackexchange-wordpress | {

How does Wordpress insert Paragraphs in posts

How can I show more than 15 themes at a time in the admin menu?
I have a lot of themes in my test wordpress site. I get a little frustrated that I can't show more than 15 at a time.
Picture.png
In pages and posts you can click "screen options" to choose the number, but it looks like "Themes" has no such option.
Picture-1.jpg
Is there another way to increase the number? | It's hardcoded into the `WP_Themes_List_Table` class that's responsible on Line 50.
$per_page = 15;
So in short, you can't without modifying a core file.
