One comment per user email per post
i have this code to limit the comments per user.
<!-- #only one comment -->
<?php global $current_user,$post;
$args = array('user_id' => $current_user->ID,'post_id' => $post->ID);
$usercomment = get_comments($args);
if(count($usercomment) >= 1){
echo 'Thank you for your comment';
} else {
comment_form();
} ?>
My question is: how can edit this code to check for the author email rather than user id
Thank you. | Try this, the code below will generate every comment by the `$current_user->user_email` for the author_email, if the `$usercomment` return something, then there is a comment by the current user so echo "thank you", but if it's not return anything output the form.
global $current_user,$post;
$usercomment = get_comments(array('author_email' => $current_user->user_email, 'post_id' => $post->ID));
if($usercomment) {
echo "Thank You";

update_user_meta duplicates entry

$aka2 = get_user_meta($user->ID, 'last_visited_blogs', true);
$aka2[] = 'blog4';

like if it contain something:
[0] => 'blog1',
[1] => 'blog2',
[2] => 'blog3'
and after function it should look like
[0] => 'blog1',
[1] => 'blog2',
[2] => 'blog3',
[3] => 'blog4'
but, what it does is, it inserts two values on execution even when it's empty
[0] => 'blog4', [1] => 'blog4'
and on every next execution it inserts two values | You are overwriting the existing values instead you should check if existing values exist and concatenate the new values to existing values if it is exist as following

Why does the page/post ID keep growing when i refresh the post-new.php file?
I created a custom post type and for debugging reasons i display the Post ID on the Add New ... page. If i refresh the page without saving or even creating a new post,(so i just press f5 on the post-new.php) the post ID is growing one by one.
Why is this happening and is this the normal behaviour? | This is normal behaviour, as I understand it.
When you load the page `post-new.php`, you run this function:
$post = get_default_post_to_edit( $post_type, true );

if ( $create_in_db ) {
$post_id = wp_insert_post(...);
}

Insert custom fields to a custom post type
I am creating a small blog about my trekking and camping experience. Since different experiences - like campsites, treks and tour operators - have different metadata, I have created a custom post types (e.g. `campsite`), associated with custom field types (e.g. `price`, `water_supply`).

What do the numbers mean at the end of add_action('save_post')...?
I've seen on a few tutorials that there are numbers at the end of the call to save Custom Fields/Meta Boxes on the `save_post` hook. For example, in the WordPress Codex it gives the following example:
<?php add_action( 'save_post', 'my_save_post', 10, 2 ); ?>
What do the **10** and **2** mean at the end?

Multiple custom fields with the same name
Is it possible to have several custom fields with the same name?
For example, I have a custom field called "promotion" for a CPT called "event". Sometimes there are more than one promotion applied to the same event, each for a certain type of participant. So I'd like to have one "promotion" custom field with a value "X, A" and another "promotion" custom field with a value "Y, B".
I tried to create this then retrieve it with `get_post_meta()` and display the result with `print_r()`, but all I get is one of the values only ("X, A").
Here's the code:
$event_promotion = get_post_meta($post->ID, "Event Promotion", true); print_r($event_promotion);
Perhaps it's just not possible to proceed this way? | Yes, it's possible to have multiple fields with the same key.
When using `get_post_meta($post_id, $key, $single)`, make sure you set the `$single` parameter to `false` (or just leave it off since it defaults to `false`).
get_post_meta( $post->ID, 'Event Promotion', false )
or
get_post_meta( $post->ID, 'Event Promotion' )
This will return an array containing every value of the key (what you're expecting). If you set `$single` to `true` it will return the first value of the specified key as a string (what you're currently getting).

Difference Between Admin and Super Admin in Database
I was looking at the user table and noticed for a super admin ( have access to network admin panel ) and an admin to a network site have same `wp_capabilities` which is `a:1:{s:13:"administrator";b:1;}` and also the `wp_user_level` is `10` for both.
So, I was wondering **what is the database value that differentiate between a super admin and an admin?** I don't see any more usermeta that relates to network admin level.
What is the proper way to assign super admin capability to a admin via:
1. Database Edit.
2. Via Code. | Site admins are stored in a site option as an array of usernames.
For example, using SQL in MySQLWorkbench you can do a query such as this:
SELECT * FROM wp_sitemeta where meta_key='site_admins';
To get back a serialised PHP array. Modifying this value by adding your username and user ID will make you a site admin.
If you're just looking to see who is a site admin, you have these functions:
get_site_admins();
is_super_admin();
If on a single site rather than a multisite, any user with the delete_users capability will be regarded as a super admin. | stackexchange-wordpress | {

Can I use add_option for a plugin categories and how?

I know that I can do it easly with new table, but I am trying to use WP built in stuffs as much as possible. | Create the ads as custom post types and register one or more custom taxonomies for these post types. You can set up the other meta data as post meta (also known as custom fields).

single-mySlug.php works: archive-mySlug.php does not. Custom Post Type
I am registering a custom post type (listing) with a plugin and it has two taxonomies. It all seems to work as expected.
I can display individual posts from the CPT using `single-listing.php` but I can't display a full page using `archive-listing.php`. I just tried `taxonomy-organisation.php` which is the CPT taxonomy and this works too.
I am using a child theme and just used a copy of the parent archive/siingle/taxonomy pages
This is a copy of WP 2012 theme file which I named `archive-listing.php`:
<
This is my CPT plugin:
<
This URL uses the archive.php file in the parent theme:
< | Your setup would mean that archive-listing.php would be used at:
<
However, your URL:
<
Is not a post archive, it's a taxonomy archive, specifically an organisation archive, and so `archive-listing.php` will never be used for it, since archive-listing is not a taxonomy archive template but a post archive template.
Other than doing an include in `taxonomy-organisation.php` there is no way to make it call `archive-listing.php`, except for messing around with hooks and filters, which I strongly recommend against as it would be a waste of time and effort ( why not just include ).

Why do I get email notifications about comments that Wordpress has already determined are spam?
I have a wordpress.org blog that I host on my own site. I have the Akismet plugin installed, and in general I keep both up-to-date (e.g. at the moment, Akismet is at version 2.5.7, and Wordpress at 3.5.1).
From time-to-time (maybe every week or so), I get a notification email from Wordpress that a (generally spam) comment needs moderating. When I log in to moderate it, Wordpress informs me that it has already been marked as spam (although I haven't marked it so, but I assume Wordpress means that Akismet has determined that). In this case, why do I get the notification email in the first place? Is Akismet failing to connect to the Akismet service, notifying me, and retrying later? If so, is it possible to turn off the initial notification email in this case? It's irritating to log in to moderate something only to discover Wordpress already knows the answer! | Disclaimer: I wrote parts of the Akismet WordPress plugin, though not the parts in question here.
> Is Akismet failing to connect to the Akismet service, notifying me, and retrying later?
Yes, this is exactly what happens. If Akismet doesn't get a valid response from the servers, it reschedules the check for 20 minutes in the future. In the meantime the post is considered held for moderation, since its actual status (ham or spam) is yet undetermined.
> If so, is it possible to turn off the initial notification email in this case?
I regret that I don't know of any good way to do this for _only_ this circumstance. But I have never had so much spam making it as far as Akismet that this happens more than once or twice a week, so I've never been bothered to make the attempt. | stackexchange-wordpress | {

How to change the name of the "edit my profile" link in the WordPress admin backend
I am really confused at this point. I can not figure it out how to rename `Edit My Profile` link in the admin backend.
How can that be done? | You could use the `wp_before_admin_bar_render` hook. You can play with code samples on the Codex page by putting them in your theme's `functions.php`.
First off you can try examining the object by outputting its contents with `print_r()`, and you'll see all the familiar items. I would probably use `remove_menu` helper and then add a new one with the modified link title, just to keep things clean.

function my_tweaked_admin_bar() {

'id' => 'edit-profile',
'title' => 'Edit Zee Profile',
'href' => admin_url('profile.php'),
'parent'=>'user-actions'

Plugin: How should I handle deleting comments?
I am writing a plugin that creates an api for a custom post type.
Users can comments on the custom post types and the comments are added using WP core comment methods.
My question arises when trying to deal with what to do when deleting a comment. I understand what methods to use, but my question is more about the general procedure.
When you make a comment it can be a reply to another comment. If the parent commenter decides to delete their comment, what should be done with replies? Should they be deleted as well?
Should their parent pointer just move one up the tree?
You could also replace the deleted comment content with a message like, 'Comment deleted'. Like a placeholder. Then the replies could keep the same parent pointer, but they would lose the context of the original parent comment's content.
Am I overthinking this? | Do not delete the comment. One comment could have multiple children, and moving the replies up would create a false impression in any case.
The real question here is **why** someone wants to delete a comment and how you could react:
* The content is obsolete or wrong: Add a note, mark it as outdated.
* The commenter disclosed something _secret_ : Replace the comment content with a note.
* The commenter doesn't want to be seen on the site anymore: replace the commenter name with _anonymous_.
In any case, I would require a reason for deletion request, and create a separate comment review queue. Use comment meta fields for that. | stackexchange-wordpress | {

Correct syntax for retrieving custom field in CPT
I don't understand when to use $post->ID or $post->post->ID with CPTs. I have :
$event = get_post( $event_id );
$event_pre_register = get_post_meta($event->post->ID, "Event Pre-register deadline", true);
Or is it : get_post_meta($event->ID ... ? | If you have the CPT's ID in the `$event_id` variable you plug into the `get_post()` call - why would you not simply just (re)use that for the first parameter of `get_post_meta()` ?
That aside, `get_post()` returns a post object (instance of WP_Post), which you choose to assign to `$event`. Hence `$event` now has a public property `$ID`, which can be accessed by `$event->ID`. | stackexchange-wordpress | {

get_user_meta() doesn't include user email?
I simply wonder why `<?php var_dump(get_user_meta(4)); ?>` doesn't contain an email address of the user. Instead I have to use
`get_userdata(4)->user_email;` to query the email of the user.
Why is that or did I miss something? `get_user_meta()` seems to provide all other aspects and informations of a user, however just not the email-address.
Matt | `get_user_meta` retrieves a single meta field or all fields of the `user_meta` data for the given user.
This means that all the values that are stored in `user_meta` table can be got using `get_user_meta`. Email is not stored as meta data so you cant get email using `get_user_meta`.
Email is stored with username and password in `user` table as user data. | stackexchange-wordpress | {

Why do some pages on my site use the previous theme?
I have developed a WordPress website using a Child Theme, I started with Twenty Ten as the base, then I created a new and improved version with Twenty Eleven as the base and some new features, now I have done it again with Twenty Twelve as the Parent theme.

Retrieve a specific post's featured image and show on a different page
What I'm simply trying to do is grab the featured image thumbnail image from a specified post/page and display that image on any other page somewhere.
So for instance, if it's a single post, use the thumbnail from post 9. If it's this page, use the thumbnail from 82, and so on.
It doesn't seem as simple as this:
$thumbnail_id = get_the_post_thumbnail(82);
Because I've tried that and it doesn't work in all scenarios.
Is there a universal way to do this? | Looks like this might be the reason why it wasn't working the way I needed.

How to i18n slugs for templates?

Is it safe to assume that a nonce may be validated more than once?

Is it safe to code with this in mind?

To be more accurate, the lifetime is controlled by filter

2, if the lifetime value makes you doubt if it is "an implementation side-effect", you may want to `add_filter('nonce_life',create_function('$v', 'return 60*5;'));` to shorten the lifetime to 5 minutes in my example.

I've tried adding Margin and Padding values in the CSS but nothing happens, I think because the padding and the margin space take the white color instead of the pink...
Can someone explain me?
thanks a lot | Well, first, it's a pure CSS question.
Second, `padding` is what you want to use.
Just change `padding: 0;` to whatever you like.
I just used FireBug to hack a padding of 1em into your code, and it worked like a charm.
**// Edit**
However, it is not just `.entry-content` but also **`.entry-summary`** that you want to affect.
.format-link .entry-content,
.format-link .entry-summary {
padding: 1em; // for example
font-style: italic;
background: #d7b5b5; //sfondo rosa
}
**// Edit** \- again
It seems, you have to work on your `style.css`.
For singular posts, you already defined a different padding:
.singular .format-link .entry-content {
padding: 1.625em 0 0;
}

See the Codex page for further parameters that you might need.

Extending arrays in parent theme without completely overriding the files
I am new to all child-theming things and trying to override an array value which is declared in one of the php files. I also don't want to override the whole php file, because it has many other functions in that file that I don't want to duplicate.
How can I do this?
The `maintemplate-somefile.php` :
...
$Icons = array(
....
);
... | I don't know exactly how your themes-- parent and child-- are constructed but the child theme's `functions.php` loads before the parent's. So, if this template is included via `functions.php` changes you attempt to make in the child `functions.php` to that `$Icons` array will be overwritten as soon as the parent `function.php` loads. Since you say this has "many other functions", it seems likely that this file is somehow included from `functions.php`.
In fact, if `maintemplate-somefile.php` is included by any file that `$Icons` array will be overwritten, as per the code you posted there is no attempt to merge that array with pre-existing values.
If this is a page template, and you provide a replace template, the parent template will not load at all.
Your parent theme might have provided a hook that you could use, or there may be some other way to achieve the end you want, but given that you posted effectively no code it is hard to say much more. | stackexchange-wordpress | {

Getting all the users who have author privilege
Can anyone tell me how to get all the users who have author privileges by querying the DB in WordPress and order them by number of posts written by them.
I use the following query to get all the users from DB:
$authors = $wpdb->get_results(
"SELECT ID, user_nicename from $wpdb->users ORDER BY display_name"
); | Unless you want to retrieve custom data from the database, you will hardly ever need to make use of the `WPDB` class (or its global object, respectively). Though it is obviously possible to do things that way as well.
Just for the sake of completeness, _if_ you had a reason to not use a more abstract function, you'd have to employ `JOIN` in the select syntax as user roles live in the _usermeta_ table.
But it'd be much simpler to make use of the `get_users` function:
$args = array(
'role' => 'author',
'orderby' => 'display_name'
);
$authors = get_users( $args );
**[EDIT]** As for the question in the comments (ordering by the number of posts):

Comments not displaying after changing theme

Action hook 'save_post' triggered when deleting posts
I developed a custom plugin which rewrite some content of my posts, but when i move a post to trash, the action hook 'save_post' is triggered and the post is not deleted.

Converting timestamps to local time with date_l18n()
I've got a WordPress cron job that sends an email periodically and saves the timestamp when it was sent as an option, and I'd like to display a date on a settings page. Something like, "The last email was sent on 'x'". I'm on the west coast of the US, so our time is currently seven hours off of UTC.
My expected output from date_i18n(), passing it the timestamp, would be a locally formatted date with a seven hour adjustment from UTC. However, it returns the time in UTC. Even trying to get the current time doesn't return what I would think would be the expected output.
For example: `echo date_i18n('F d, Y H:i');` outputs April 05, 2013 11:36 as expected, but `echo date_i18n('F d, Y H:i',time());` outputs April 05, 2013 18:36.
Is this intentional? How can I return a locally formatted date from a preexisting time stamp? Thanks for any help. | I know I'm three months late, but the function you want here is WordPress' `get_date_from_gmt()`.
The function accepts a GMT/UTC date in `Y-m-d H:i:s` format as the first parameter, and your desired date format as the second parameter. It'll convert your date to the local timezone as set on the Settings screen.

updating meta_key from the frontend
I am wanting to update the meta_key in the database to reorder postmeta from the frontend. I'm using jQuery UI drag and drop to move items into an order, I can update the values but the meta_key is not so easy. My meta_key and values are like this:

* add_task_0_complete => value
* add_task_1_assigned => value
* add_task_1_complete => value
* add_task_2_assigned => value
* add_task_2_complete => value
* add_task_3_assigned => value

Any help or guidance would be appreciated. | I don't have time for a detailed reply but some ideas:
1) Use arrays in the front end. Make your input ID's like `add_task_assigned[]` and `add_task_complete[]` \- these appear as arrays in the back end. It's not great practice, but it works.
2) Use an array in the backend. Store the meta as
`array( [0] => array( 'assigned' => true, 'completed' => true ), [1] => array( 'assigned' => true, 'completed' => false ) )`

Structure for projects and clients
I have a client who has requested a WP based portfolio where they will present their projects and clients, filtered by categories and tags. They also wish to filter all projects done for a particular client. I decided to use regular posts for the projects, but I'm unsure as to what would be a good setup for clients.
My idea is to have a custom post type named clients, in which the user can create clients that are then made available in a custom field select list in each post. This would make for a robust structure but it seems a bit unnecessarily to have to use a custom post type simply to achieve this. Any ideas on a more effective approach? | It sounds like you need both clients and projects to have "post-like" capabilities, meaning that using a taxonomy for clients wouldn't make much sense.

Automatically Generated Menu pages
I am a designer for a website, which I had a developer build in wordperss for me.
Each time a new page is created, it is automatically added to my menu bar. Is this something the developer has built into the code, or is it something I can turn off? | There are two major things you need check for to resolve this. If your site is using the WordPress menus, then under Appearance | Menus is a checkbox that if ticked will automatically add all new top-level pages to the menu. Unticking that box will stop the behavior.
If you check that area and no menus are defined, then the theme is using wp_list_pages() to generate a menu. If the menu bar appears at the top of the content, then check the theme's header.php file for the function. If your menu is on a sidebar, check for the function in sidebar.php.

Get page IDs from nav items

What am I doing wrong? | Menu items are stored in the `posts` table with a `post_type` of `nav_menu_item`. So, what you are returning is the ID of the menu item itself, not what it points to.
The page/post ID that the menu item refers to is stored in the `postmeta` table, with a `post_id` that matches the menu item `ID` and `meta_key` = `_menu_item_object_id`. The easiest way to get the `meta_value` (ie the page being pointed to by the menu item) is to use something like this:

Link or button to open the media manager from frontend

Javascript 2 elements dependent onclick .toggle

});
});
jQuery(document).ready(function(){
jQuery('#create-account').live('click', function(event) {

});
});

Get author ID with attachment ID

In order to do that, I assumed the easiest way would be to compare the ID of the current, logged-in user with the ID of the user who created the attachment. But there doesn't seems to be a way that I can find to get the ID of the author of a post outside of the loop using only the attachment ID.
I'm stumped, how should I do this? | Back in the day I wrote a function to check for that (you can put it in **functions.php** and call it from your page):

if(isset($res) && count($res) > 0) {
return $res[0];
} else {
return false;
}
}

$current_user_id = get_current_user_id();
$post_data = get_post($your_att_id, ARRAY_A);

Access for adding subpages but not for pages
For every website project, i make the wordpress admin custom for the client. Right now, i want that the client only has access to add subpages.
I have a main navigation on the website. I want that the main navigation is fixed, so the client can not add pages to the navigation. But the client can add subpages to the current pages in the fixed main navigation.
I googled it, but i can't find a solution. I know i can show menu items on a specific id. So i can make the main navigation fixed.
Example:
<?php wp_list_pages('include=7,13,26,35&title_li=<h2>' . __('Pages') . '</h2>' ); ?>
But, does it show the subpages id's thats below the page id? And is there not a cleaner way? Because with this solutation the client has still access to create pages. I only hide the created pages on the front website.
Hope someone can help me.
Many thanks, | `wp_list_pages` simply lists pages. It isn't a menu and doesn't use the navigation menu APIs. For what you want you'd need to do several queries to find the subpages of those page IDs, so in your case 4 queries, and you'd need to do 4 wp_list_pages calls, and a manual query to get the top level pages. This will not be fast, and is wasteful, kludgey, and a bad idea.
So instead you should be using `wp_nav_menu`. Use a standard nav menu, if your client modifies this then charge them to put it back ( serves them right, they were warned, but it is their site, and they paid for it, so why shouldn't they be able to? ).
With a standard nav menu you can add non-page items, rearrange items, and submenu items don't have to follow the page structure. | stackexchange-wordpress | {

Show the title of the latest post by author

Rename "Add Media" Button To "Add Images"

Why is this page using the homepage template and not the one it should?
* * *
One of my clients has installed a theme where when a visitor enters their username and email to register as a new user they get shown a link to download a custom report file.
This was working fine on my clients test installation, but now they've converted the site to a live site the download link doesn't show and instead the page uses the homepage template...
I'm stumped as to why it's happening so any advice would be great.
Here's the test page
Here's the live page
Here's a jsFiddle of the PHP code | The difference between the two is that the test site has pretty permalinks enabled and the live site doesn't. If you look at the URL, the issue becomes apparent, this is not a valid URL/query string:
If you change the second `?` to an ampersand, the page renders correctly.
Either enable pretty permalinks on the live site, or modify your code with `add_query_arg` to correctly append the additional query argument:
<input type="hidden" name="redirect_to" value="<?php echo add_query_arg( 'register', 'true' ); ?>" /> | stackexchange-wordpress | {

IF Custom field value equals ZERO

<div><?php echo do_shortcode('[shortcodes]'.$mp_buy_button.'[/shortcodes]'); ?></div>

However it is interperting as a value of anything, thus displaying the div, but I need it to check for the number 0. How can I fix this? | You are using get_post_meta incorrectly, so it is returning FALSE every time. As PHP equates '0' and FALSE, your div will always be displayed.
The correct syntax for get_post_meta is:

// display error message here but the page redirects anyway...
} else {
update_post_meta( $post_id, '_custom-meta-items', $related_items );

}
how do I display an error here instead of saving the custom post meta? | Short of doing some jQuery validation, I think the only option is `wp_die()`.

Customized landingpages for categories
When I click on a category now, it looks like..
> Category Archives: MyCategory
>

> second post

You could create for each category an individual PHP file:

* or `category-{CATEGORY SLUG}.php`.

Here's a short example using the ID:
$category = get_the_category();
$cat_ID = $category[0]->cat_ID;
switch ($cat_ID) {

...

WordPress and the server conspire to lie about the location of files, at least when pretty permalinks are on. If they are off you will notice that most requests go through `index.php` and pages are loaded via various `$_GET` parameters but are not loaded directly.

Wp admin - Set default value to 999 in comments
When you are at the comments menu in wp-admin you only see 20 comments at the time, so if you want to delete alla comments you can **ONLY** mark the 20 comments you see on current page. It dosent mark comments that are on the next page.
Found a solution but dont know where to look for it
In WP-admin -> Screen layout there you can see that its only set to 20 comments a page. I know that i could just access the screen layout and set it to maximum (999 comments a page).
Now the question is can I set that value (999) to default for every user i create ? Or just basicly for the whole network?
**Follow question:** : If its possible, then whats the best way to do it ?
**NOTE** : Im using latest WordPress version with Multisite network. | You can use
add_filter('edit_comments_per_page', 'return_999');
function return_999(){
return 999;
}
since the user options are filtered in the `WP_List_Table::get_items_per_page()` class method :
/**
* Get number of items to display on a single page
*
* @since 3.1.0
* @access protected
*
* @return int
*/
function get_items_per_page( $option, $default = 20 ) {
$per_page = (int) get_user_option( $option );
if ( empty( $per_page ) || $per_page < 1 )
$per_page = $default;
return (int) apply_filters( $option, $per_page );

So you could do the same for `edit_post_per_page` and `edit_page_per_page`.
Or if you have other custom post types: `edit_{CPT}_per_page`. | stackexchange-wordpress | {

Wrong date returned by get_the_time
I have this line of code :
$registration_date = get_the_time('F j, Y').' at '.get_the_time('g:i a');
I just ran this on my BlueHost hosted website and it returned : January 29, 2013 at 12:54 pm
However, on the same site I can see in the dashboard that post publication dates are correct. | get_the_time() function returns the time of the current post within loop.
If you want to display today's date then use date function of core php. | stackexchange-wordpress | {

Remove wrong dashes from get_the_title()
I have a particular CPT post that has a dash (-) in its title. I copy this title in a variable `$var` using `get_the_title()` then I create a custom field somewhere else with a value equal to `$var` : `add_post_meta($my_post_id, 'some_name', $var);`
Problem: in the custom field, the dash became a HTML entity with a "&", "#" and a 4-digit number number.
Why, and how to fix the problem? | `get_the_title()` is treated with `wptexturize()` by default. That changes the dash.
To fix it remove the filter and reapply it if it was really set:
$wptexturize = remove_filter( 'the_title', 'wptexturize' );
$title = get_the_title();
if ( $wptexturize )
add_filter( 'the_title', 'wptexturize' ); | stackexchange-wordpress | {
