Is there any option to access a function inside function.php through a url?
Like joomla has this.
Any idea?
Use ajax functionality of wordpress:
HERE
You can use nopriv actions for that.
wp-admin/admin-ajax.php is the url for the ajax page of wordpress.
Or either you can make a template page which gives only content and create a shortcode
and add to a specific page.
functions.php is part of the core of your theme and is automatically included.
to access your function, simply use it in your theme file, as such:
<?php myfunc(); ?>

I have a custom page template built in a child theme and I need to call out a custom header.
I have template-home.php page template calling out
<?php get_header('home'); ?>
for the header.
I have a saved wp-header-home.php with a little custom button that I need to get.
The page template is unsuccessful at calling out the custom header-home, rather it's calling out the default wp-header.php. I can see when I add my changes into that file, they're reflected.
So, what's going on? Why does my
<?php get_header('home'); ?>
not work to get the wp-header-home.php? What am I doing wrong?

Create the file with header-home.php
In wordpress how can we use functions like is_user_logged_in(), we can use this function in any page like header.php , sidebar.php
In wordpress page we are making a form which will be submitted using ajax. Suppose we are gatering form's data on a page 'submitform.php' whose url is www.mysite.com/submitform.php which is totally a custom page.
Now how will I be able to know using is_user_logged_in(); function whether user is logged in or not. because submitform.php is a simple page outside wordpress.
At the top of your custom PHP file, use the following to load WordPress core functionality. This assumes your file is in the root of the installation:
define('WP_USE_THEMES', false);
require('wp-blog-header.php');
I am trying to write a plugin for wordpress. I have a problem i can't solve.
Inside plugin i habe added a shortcode that show a form.
function showForm() {
echo '<form method="post" action="www.example.com/myDestinationPage">';
[...]
}
add_shortcode( 'ShowFormSC' , 'showForm' );
After that, in a page, i added the shortcode and it works perfectly. ;-)
Now the problem: how can i read POST data in myDestinationPage (another wordpress page)?
In Php would be very simple ... but in wordpress I do not know how to do.
Second problem: myDestinationPage must be a real wordpress page with another shortcode inside, or can be defined as a "virtual" page inside my plugin?
Thank you for your help!
Best Regards,

www.example.com/myDestinationPage needs to be edited to recieve the post data, just as in any other php script, wordpress or not. If 'myDestinationPage' resolves to dynamic wordpress content, then you are in muddy waters.
Let's say, myDestinationPage is a wordpress Post. That "page" doesn't exist as a file, it comes directly from the database.
You could write a shortcode which handles this though:
add_shortcode('post_parser', 'postParser');
. . .
function postParser() {
filter_input(INPUT_POST, 'my_post_value');
//do something
}
Then, you just add the '[post_parser]' shortcode to the myDestinatioPage Post. (You mentioned it's a wordpress page, but page & post are both WP_Post objects.)
Another option is to put your post processing code in the post.php (or whichever template myDestinationPage is).
1st answer: you can directly use $_POST in wordpress like in php.
2nd answer: Yes you can. If you want to use pages in your plugin, use plugins_url() to generate the path for form action.

I have written a security function.
I want to call this function in all pages which are created by wordpress back end only.
(Does not want want to called by all php files).
Is there any hook available?
you can use in a php file (like header.php or functions.php) like this
if(is_page())
{
// code to execute on all pages
}
You can tie it to the 'wp_head' hook.

I need to access the footer inside a wordpress theme via a url. Ideally it would just render the footer data and nothing else, alternative suggestions welcomed though.
To add some context, the data will be fetched through the url and a script will read the markup. This data will then be cached and available through Magento where it is needed to be displayed..
Is there a url path that will display it or should I make a new page that can be called via the base-url+the-page-name???
There's nothing built in to do that. You could use the AJAX API in your theme or a plugin and accomplish it.
You hook into an action that gets sent as a URL or POST data parameter and then make a request to yoursite.com/path/to/wordpress/wp-admin/admin-ajax.php.
<?php
add_action('wp_ajax_so20495429_display_footer', 'so20495429_display_footer');
add_action('wp_ajax_nopriv_so20495429_display_footer', 'so20495429_display_footer');
function so20495429_display_footer()
{
get_footer('ajax');
}
This will work for all users, logged in or not, despite the wp-admin URL. Here is code above wrapped up in a plugin.
what you can do is make a wordpress custom page template.
If you dont know how heres a little tutorial : http://www.expand2web.com/blog/custom-page-template-wordpress/
Now you want the custom page template to only load the footer (add the html, head and body opening tags yourself)
if you create a new page with your page template seletced it will only output the footer.
Hope you can get it to work

What about $footer_url=get_template_directory_uri().'/footer.php'; ?
