I have WordPress plugin that displays a recipe for food. I want to customize ingredients before displaying it. So I'm using the plugin hook to do this. I have create my separate plugin (functions.php) to customize the data before displaying. When I run the page I get ingredients Array() in my customize_recipe_field($arg) function and change ingredient using the ingredient name:
$arg[$key]['ingredient'] = $data['ingredient']."-Demo";` simply add "-Demo"
After that I print the $arg and I get the changes that are done by my plugin function, but when it displays on web page no changes are done. It still shows the old data.
Here is customize function:
function customize_recipe_field($arg) {
foreach ($arg as $key=>$data){
$arg[$key]['ingredient'] = $data['ingredient']."-Demo";
}
return $arg;
}
add_action('recipe_field_ingredients', 'customize_recipe_field');

currently my theme on WordPress is Neve , and my posts all over the blog shows the following meta info :
https://i.stack.imgur.com/ynu71.jpg
where :
1- post title
2- post author
3- post date
4- post category
i want to replace these post meta with similar to this:
https://i.stack.imgur.com/Xywa9.jpg
for this purpose i have created a child theme and then installed snippet plugin to add php code easily and deactivate it once it is not working . unfortunately i could not find the code that can do the required modifications on that post meta :
https://i.stack.imgur.com/uwCrS.jpg
can any one provide a full php code to modify all these changes in one time after pasting into snippet ? or if there is another way i can do it ?
You'll have to create a child theme (already done) where you can override the current blog post template, instead of using a snippet plugin. To do this, copy the blog post template file from your theme and add it to your child theme.
WordPress will now read your child theme template instead of your theme's template, and you can easily modify the DOM from there, and shape the layout/text however way you want. (You can use the theme editor built-in in WordPress to modify the new child theme file. No plugin required.)
This is the proper way to modify a post page without plugins, and you can easily grab thing such as a post date, author, etc. via WordPress' built-in function. Example of how to get the author name of a WordPress post in PHP.
As for, 'latest edition' date, I will lend you a snippet I wrote for a client as WordPress. This will return the date at which a post has been modified as long as it is different from the publishing date (tweaks are common right after publication so it's a tad pointless to show a "last edited date" as the same as the publication date).
function current_post_last_edited_date_formatted() {
if(get_the_modified_date() !== get_the_date()) {
return '<p class="last-edited"> Last edited <span class="data">'.current_post_last_edited_date().'</span></p>';
} else {
return '';
};
}
The function you see called in the condition are WordPress core functions. =)
I have a custom WordPress plugin that handles authentication.
There's a function logTheUserIn() inside plugin-name/src/Classes/Auth.php.
I need this function to be run when a user hits a custom WordPress template page (page-authPortal.php), which has this code at the top:
include_once('wp-includes/pluggable.php');
include_once("wp-content/plugins/ad-auth-bridge/src/Classes/Auth.php");
print "test";
I created a WordPress page titled "authPortal" and it shows the 'test' text, so I know the custom page is being loaded and rendered. Now I just need to fire off logTheUserIn().
I have tried adding shortcodes and actions inside Auth.php:
class Auth {
public function InitHooks() {
add_shortcode ('authNow', 'logTheUserIn');
add_action ('authAction', 'logTheUserIn');
I've then tried to use the actual shortcode [authNow] inside the WordPress editor, I have also tried do_shortcode and do_action.
What am I missing here?
Thank you!
There is no need to include or require the plugin fields. They are initially loaded by WordPress.
First, in your template, make sure your plugin is active and the function/class is reachable:
if ( function_exists( 'logTheUserIn') ) {
logTheUserIn();
}
Then fire the function right within your template.
In your case, you might need to check if class_exists, then initialize the class
In my plugin i have created a custom template that prints a requested sidebar. and for running the code of this template i assigned a custom page to it (by calling update_metadata) .
Is it a good idea for getting content of a specific sidebar into Ajax call ?
Now my problem is that WORDPRESS shows it in the dashboard and front page , and after searching i have not found any easy to understand solution for Hiding a page completely so only can be accessed by its id .
Can any one tell me how to do that ?
you are going about this the wrong way. You can create a function that can create anything that can be created on a wordpress page.
But if you really must you can create a page outside of the database, etc:
add_action('init', 'add_rewrite_rule');
function add_rewrite_rule(){
// add_rewrite_rule(REGEX url, location, priority (i.e. top is before other rewrite rules)
// I created a custom post type for this plugin called market -- replace post_type with whatever you want
//basically tell wordress to add a query var if sidebar is added to url.
add_rewrite_rule('^sidebar?','index.php?is_sidebar_page=1&post_type=market','top');
}
// register a query var
add_action('query_vars','market_set_query_var');
function market_set_query_var($vars) {
array_push($vars, 'is_sidebar_page');
return $vars;
}
// associate a template with your quer_var
add_filter('template_include', 'market_include_template', 1000, 1);
function market_include_template($template){
if(get_query_var('is_sidebar_page')){
$new_template = (theme or plugin path).'/pages/yourpage.php'; // change this path to your file
if(file_exists($new_template))
$template = $new_template;
}
return $template;
}
This will not be a page that will be in the admin section or in any query that relates to pages but someone could of course navigate to this page. But as i said above you would be better to create a function to create your sidebar. If you want a seperate file to handle the "view" you use require_once 'filename'; a file and keep your functions area free of html.
If you are creating functions in a wordpress plugin dont forget many functions may not be available until later in the load process. Use add_action() if you run into any undefined functions
edit:
you are loading wordpress before you get to the template so you have all the functions. (google wp load for more info) + get_header() / get_footer() will also load a few things like css, etc. I had a small typo in the code above, fixed that but basically what you are doing is telling wordpress if someone lands on www.example.com/sidebar to apply a query_var (rewrite rule). Wordpress will look up its saved vars (final function) and return the template assoc. The 2nd function just registers the var.
You also have wp_functions in any file you create and include in a plugin, etc hence why you can create a file that does exactly the same as this page.
is it possible to make a custom page for buddypress with its url like this: http://domain.com/custom_page ? I found some answers by searching google but it does not create a custom page. i have a code here that i found in one of the blogs.
define('BP_FUN_SLUG','fun');
function bp_show_fun_page() {
global $bp, $current_blog;
if ( $bp->current_component == BP_FUN_SLUG && $bp->current_action == '' ) {
// The first variable here must match the name of your template file below
bp_core_load_template( 'fun', true );
}
}
add_action( 'wp', 'bp_show_fun_page', 2 );
but this code does not work... Is anyone there knows how to do this? thanks
Yes, it is possible to create a new page in Buddypress.
In Buddypress you have to create a new plugin or create a function in the theme functions file.
For creating first you have to add a new page link in navigation menu using bp_core_new_nav_item() function (You have created sub menu for that use bp_core_new_subnav_item() function).
Above two functions pass the screen function name as a parameter this name use when you click the custom page link call to this screen function. Create new function in your functions.php file same as screen function name. In this function call to your custom template file using bp_core_load_template() function.
Then finish, add more logic to create a new function and call it in the template file.
Another approach is to add a plugin that allows php in posts. For example http://wordpress.org/extend/plugins/allow-php-in-posts-and-pages/
Then create a page and add this to it:
[php] locate_template( array( 'some-template-folder/something.php' ), true ); [/php]
In case someone is wondering how to integrate custom pages into user profile (so that it looks like activity stream, groups etc.).
One thing i did recently was define a plugin (functions.php would work as well), register a custom slug with bp_core_new_nav_item or bp_core_nav_subnav_item and loaded member/single/plugins.php template in the handlers for those slugs. There are a bunch of actions on that page that you can hook into like bp_template_title and bp_template_content.
This can give you a whole lot of control.
Here's a link to the source of plugins.php: http://phpxref.ftwr.co.uk/buddypress/nav.html?readme.txt.source.html
I want my WordPress blog to have a page called music. On that page I will query the DB for posts with the category music and then change around the look and feel of the posts. So I can't just put a link to /categories/music/ because I want to do custom work on the posts.
Should I put this code in a separate php file and link to it? I think I may lose access to all the nice WordPress API calls if I do that.
I was thinking about using a filter, but I am not sure which one to use. I was thinking something like the following except the_title has not been grabbed yet so I cannot check the title.
function show_music(){
if( is_page() && the_title('','',false) == 'music' ){
echo "got here";
}
}
add_filter('pre_get_posts', 'show_portfolio');
How would you go about this?
You need to put the below code in the file, and then put the file in the Theme folder. Then you can create a page using Wordpress pages and select a page template with the name you put in this comment:
/*
Template Name: Something Goes Here
*/
You need to create custom page within your theme. If you dont have idea how to create custme page or template page in WordPress theme then view my easy tutorial How to create template page in WordPress
