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,
Simone
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 am trying to make a plugin that will display custom page when a parameter is present in the URL. For example, let's say that the URL of a post is localhost/wp/2018/03/22/postname/, it displays post normally as expected. What I want to achieve, is when I specify URL as localhost/wp/2018/03/22/postname/?param=1, I want to display page that I will generate with the plugin. I made a function that works when the parameter is present and it echoes some example content, however, it merges with what WordPress normally displays. So when I put the parameter into URL I get a regular page with post and my content somewhere in the middle. I want to display only the page that i generate from scratch, from <html> to </html> with my plugin. How can I do that?
There is a filter in WordPress called template_include this filter is executed before any output is displayed on the WordPress generated page.
You can override the current template via this filter as soon as you find the parameter and value in the URL. E.g. below is a filter I was using in a project to override archive & single template for a certain CPT:
function em_templates($template) {
if(get_query_var('post_type') == 'xyz' ) {
return FMM__DIR__ . '/templates/archive-xyz.php';
}
return $template;
}
add_filter('template_include', 'em_templates', 1, 1);
You can adopt this logic for parameter and use this WordPress filter to take over the template process and display yours own.
so we are making a wordpress site that automatically adds a link to a comment every time a comment is created. The theme we are using is html5 blank. I have written several lines of code into its function.php. however it is not working right now, here is what i wrote:
function bo_wrap_comment_text($content) {
$content = get_comment_text();
$texta = urlencode(get_comment_text());
$textb = "http://www.google.com/search?btnI&q=" + $texta;
return ''.$content.'';
}
add_filter('wp_insert_comment','bo_wrap_comment_text',1000);
a separate code(this one works) is tested here: http://phpfiddle.org and the code is:
<?php
$texta='i hate apple';
$textb=urlencode($texta);
$textc= "http://www.google.com/search?btnI&q=".$textb;
echo ''.$texta.'';
?>
the wordpress site is here. It is simply a static front page. the title you see there is the title of comment area. everything related with blog posts has been hidden using css. we have manually added links to several comments as prototyping. what we want is replace manual work with wordpress functions. I would really appreciate any help.
You need this hook instead to edit comment data:

How can I place a default text (hashtag) in the Custom Message?
The textarea is (located in line 643) under jetpack/modules/publicize/ui.php
I tried to put the text in front of $title in various ways, like:
<?php echo "#myhashtag $title"; ?>
or
<?php echo '#myhashtag '.$title; ?>
but it just echoes the text, not the $title.
Any ideas will be greatly appreciated.
You can use the approach of this Wordpress plugin i made (Publicize With Hashtags), which does exactly that. It basically use and action trigger bound to the 'save_post' native event.
If you want to develop your own one you can have a look at my Source Code on the project's GitHub page or in this installation & usage guide I wrote about it.
You can add a filter, like so, to your theme's functions.php or a site-specific plugin:
add_filter( 'wpas_default_prefix', 'add_default_publicize_hashtag_prefix', 10, 4 );
function add_default_publicize_hashtag_prefix() {
$default_tags = '#yourhastaghere ';
return $default_tags;
}
This will add your default hashtag before your title without you needing to hack the WordPress core.
jetpack/modules/publicize/ui.php itself states in its comments:
/**
* Only user facing pieces of Publicize are found here.
*/
You added your hashtag in the textarea which allows admins to enter a custom message (click edit and it will slide down with your hashtag).
As #Yazmin mentioned, the best way to permanently edit the message is using a filter. The filters available are wpas_default_prefix, wpas_default_message, and wpas_default_suffix.
Personally, I had no success using these filters and I'm interested in a working solution to this issue myself.
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 $footer_url=get_template_directory_uri().'/footer.php'; ?
I'm trying to make a custom Taxonomy Term page in Drupal 7. I've created a page--taxonomy.tpl.php file in my templates folder. The file only prints out a message. I now try to force the template file by adding
function template_preprocess_page($variables) {
if (arg(0) == 'taxonomy') {
$variables['template_file'] = 'page--taxonomy-tpl';
}
}
in my template.php, but it won't work. Can you help me? And if I get the custom page working, how do I fetch the nodes with this term (in page--taxonomy.tpl.php)? Thanks in advance.
Try using this in your template.php:
function template_preprocess_page(&$variables) {
if (arg(0) == 'taxonomy') {
$variables['theme_hook_suggestions'][] = 'page__taxonomy';
}
}
You need to pass $variables by reference, so add a & before it
template_file has changed to theme_hook_suggestions in Drupal 7
You don't need the -tpl in the template suggestion unless you want it to be a part of the filename like "page--taxonomy-tpl.tpl.php" which I don't think is what you want.
For more information, check out template_preprocess_page(), theme_get_suggestions() and Working with template suggestions
Not sure if this would meet your requirements, but one of default D7 views - Taxonomy term - emulates Drupal core's handling of taxonomy/term pages. You could just enable it (it would automatically replace Drupal's core taxonomy URLs), and then do whatever you want with it, keeping original page structure, all blocks etc, using Views' page templates (see "Theming information" in "Advanced") and all other bells and whistles...
Since you are using Drupal 7, you could also create a file name "taxnomy-term.tpl.php" and edit according to your needs.
See taxonomy-term.tpl.php
Full control over the taxonomy term page can be obtained using hook_menu_alter() . See https://drupal.stackexchange.com/questions/48420/theming-and-overriding-taxonomy-term-vocabulary-page/111194#111194
