HI i was just wondering certain things about developing a plugin for myself the right wordpress way. In terms of wordpress constants and renaming the wp-admin. how would be the best way to create a plugin that defines certain wordpress constants such as wp-debug, wp_cache, SITECOOKIEPATH, ADMIN_COOKIE_PATH. Ive seen plugins such as W# total cache that write onto the wp-config in order to define WP_CACHE constant. Ive also seen some security plugins that in turn change the template of the login page in order to change the wp-admin. Is it ok and secure for me to recreate the functionality of w3 total cache in order to add and change wp constants on the wp-config?

Guido on "Get widget instance with wp_options"
Hi again,
I have a widget with wp_options name: my_widget.
Within my widget file I can retrieve a value like this:
if ( !empty( $instance['title'] ) ) {
echo $args['before_title'] . apply_filters( 'widget_title', $instance['title'] ). $args['after_title'];
}But how do I retrieve this value outside the widget file?
I've read something about get_option, but don't understand how to get a single value from my my_widget option, such as: $instance['title']
Thanks in advance!!

Mariah_A_C on "wp_handle_upload () setting $overrides correctly"
Yes I have searched and yes I have found lots of answers, but I am not sure I have found the correct answer.
I have a form with an image upload. I am using wp_handler_upload() to upload the image to my uploads file. The code works fine as long as 'test_form' => false is in the $overrides array. So here is my question everything I have found online says to set this this way, but in the codex it says
$overrides
(array) (optional) An associative array to override default behaviors. When called while handling a form, 'action' must be set to match the 'action' parameter in the form or the upload will be rejected. When there is no form being handled, use 'test_form' => false to bypass this test, and set 'action' to something other than the default ("wp_handle_upload") to bypass security checks requiring the file in question to be a user-uploaded file.Default: false
The source file says
// All tests are on by default. Most can be turned off by `$overrides[{test_name}] = false;
$test_form = isset( $overrides['test_form'] ) ? $overrides['test_form'] : true;
$test_size = isset( $overrides['test_size'] ) ? $overrides['test_size'] : true;`// If you override this, you must provide $ext and $type!!
` $test_type = isset( $overrides['test_type'] ) ? $overrides['test_type'] : true;
$mimes = isset( $overrides['mimes'] ) ? $overrides['mimes'] : false;`// A correct form post will pass this test.
` if ( $test_form && ( ! isset( $_POST['action'] ) || ( $_POST['action'] != $action ) ) ) {
return call_user_func( $upload_error_handler, $file, __( 'Invalid form submission.' ) );
}`
So my questions are first how do I set action to my forms action parameter? I tried 'action'=>'' which didn't work.
Second is setting 'test_form' => false just an easy fix that is bypassing a security measure? or is it really supposed to be set that way? The only example in codex uses it and every example I have found online uses it, but it says a form should be able to pass the test. I am so confused.
Here is my current code:
if ( ! function_exists( 'wp_handle_upload' ) ) {
require_once( ABSPATH . 'wp-admin/includes/file.php' );
}
$uploadedfile = $_FILES['fileToUpload'];
$upload_overrides = array( 'test_form' => false, 'mimes' => array('jpg' => 'image/jpeg', 'png' => 'image/png') );
$movefile = wp_handle_upload( $uploadedfile, $upload_overrides );
if ( $movefile && !isset( $movefile['error'] ) ) {
echo "File is valid, and was successfully uploaded.\n";
//var_dump( $movefile);
$image=$movefile[url];
} else {
/**
* Error generated by _wp_handle_upload()
* @see _wp_handle_upload() in wp-admin/includes/file.php
*/
echo $movefile['error'];
}and the form
<form method="post" action="<?php echo htmlspecialchars('');?>" enctype="multipart/form-data">
<input type="file" name="fileToUpload" id="fileToUpload"><br>
<input type="submit" name="submit" value="Save">
</form>↧
andy.newby on "Getting stuff out of the main script-loader.php"
Hi,
I'm trying to optimize my site, and as such want to put some stuff into a core file, and other stuff get rid of. For example, the jquery-migrate one I want to get rid of.
In wp-includes/script-loader.php, we have stuff like:
// jQuery
$scripts->add( 'jquery', false, array( 'jquery-core', 'jquery-migrate' ), '1.11.3' );
$scripts->add( 'jquery-core', '/wp-includes/js/jquery/jquery.js', array(), '1.11.3' );
$scripts->add( 'jquery-migrate', "/wp-includes/js/jquery/jquery-migrate$suffix.js", array(), '1.2.1' );I want to get rid of those, and change it for the 2.2.2 version (without migrate). I this may cause issues with some plugins, but I'm willing to take that chance.
Then, we have stuff like:
$styles->add( 'thickbox', '/wp-includes/js/thickbox/thickbox.css', array( 'dashicons' ) );
I want to take that CSS out (as I know its not going to change), and plop that into my main CSS file. However, I don't seem to be able to do this in the themes functions.php script - any suggestions as to how it can be done?
Thanks!
Andy

blueclochard on "WP 4.4: remove json-api and X-Pingback from HTTP Headers"
Starting with 4.4 WordPress adds a new HTTP Header. It looks like this:
Link: "<http://www.example.com/wp-json/>; rel="https://api.w.org/""
Does anyone know how to remove it? I know the REST API can be disabled, but I still would like to remove the HTTP Header as well.
Also starting with 4.4 old methods to remove the X-Pingback HTTP Header no longer work. This is the header I am talking about:
X-Pingback: "http://www.example.com/xmlrpc.php"
I would be very happy if anyone could tell me how to remove both of these headers.

Hi guys,
I'm trying to make a filter to remove a Woocommerce Checkout Add On, so it doesn't show for logged in users. It's a field that requires customers to buy a membership before checking out - but obviously they don't have to, when they return to buy more and already have an account and a membership.
I've tried this, but it's not working.
add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );
function custom_override_checkout_fields( $fields ) {
if( is_user_logged_in() ){
unset($fields['wc_checkout_add_ons_2_field']);
$fields['wc_checkout_add_ons_2_field'] = array();
}
return $fields;
}
Could someone please help point me in the right direction?

Hi all, as I'm working on plugins and exploring the WP core, I find that I often need to connect to MySQL to check something. I wrote a tool that searches for the wp-config.php file from any WP directory and returns the connection string.
$ pwd
/var/www/wordpress/public_html/wp-content/themes
$ wpdb
mysql -u"AzureDiamond" -p"hunter2" -h"localhost" some_db
$It can optionally connect directly or produce a mysqldump string complete with suggested time-based filename:
$ wpdb -c
Welcome to the MySQL monitor. Commands end with ; or \g.
mysql> SELECT COUNT(*) FROM wp_posts;
+----------+
| COUNT(*) |
+----------+
| 351 |
+----------+
1 row in set (0.01 sec)
mysql> EXIT;
$ wpdb -d
mysqldump -u"AzureDiamond" -p"hunter2" -h"localhost" some_db --skip-opt > some_db_2016-02-10_1602.sql
$You can get the tool from my Github repo:

TrisectDevelopment on "Login to WP from PHP"
I'm working with custom pages in WP and I have beeb making a few pages.
In the database I have created a new table for profiles.
I have made a custom PHP page where you can create a new profile. At the same time it creates a new WP user.
I have also made a custom PHP page where you can login to the system (new table).
Here in this file I want to also let the user login to WP, but here I have failed so far.
Heres the code I have tried:
$creds = array(
'user_login' => 'username',
'user_password' => 'password',
'rememember' => true
);
$user = wp_signon( $creds, true )When I then go to /wp-admin page is okay, but I have an forum page that only WP users can se and this page I'm not allowed to visit.
If I login to WP with the same credential the normal way (wp-login) I can see the forum fine.
So my question is simply:
How do I login to a WP site in PHP code?
After login I want to go the the main page of the site.

waubau on "Get all post types, taxonomies and terms"
Hi,
For a plugin I need to get all the registered custom post types, its taxonomies and their terms.
As I currently see the solution I need two nested loops:
Get all the post types using get_post_types(). Then loop foreach post_type with get_object_taxonomies() to get all associated taxonomies and then loop foreach taxonomy with get_terms().
As a result I will get 3 nested arrays of post_types -> taxonomies ->terms.
The solution looks feasible but a bit complicated. Is there any way just to get some kind of post_type object with all these taxonomy and terms data in one go?
