Is there a way to get the Podcast Name, Episode Title, and Date through a link inserted in a wordpress post?
I'm using ACF plugin where the user may insert a podcast link.
Like what happens when I paste a link in WhatsApp, and an information with appears containing even an image or a logo from the website pasted.
Thank you.
AMP.
Yes!
Option 1
You could hook into the save_post hook, get the url that has been supplied, grab the data from that url with either curl / file_get_contents / whatever and then save the data as post meta for that post.
On the frontend, you can grab the saved data from the post meta.
Option 2
You could also grab the data on the frontend. Either with php in wordpress, or on the client side with js (e.g. axios or fetch). You get the acf link and pass it to e.g. window.WP_VARS, for your clientside code to use it. I e.g. use this to pass generic vars to my clientside code:
wp_register_script('mainjs', get_template_directory_uri() . '/js/main.js', array(), REL_VERSION, true);
wp_localize_script('mainjs', 'WP_VARS', $generic_vars);
wp_enqueue_script('mainjs');
The advantage of this is that you don't have to store and grab this data from your database. Make sure that the fetch is non blocking, so do it on page ready.

I am writing a WordPress plugin that has an AJAX element to it - blocks of HTML are fetched by the front end from the plugin using AJAX.
I am having difficulty joining up the pieces here, and I suspect it is just a terminology issue. How would I implement a page completely provided by the plugin?
The content of the page will be HTML - the plugin can generate this in response to POST or GET parameters.
There needs to be a route to this page. The route does not have to be user-friendly or a REST style - just some kind of URI that gets to the plugin. Is there perhaps a way to register a custom page with an arbitrary name, without having to create it as a WP post?
I would like all this to be self-contained in the plugin, so should not involve the administrator having to create posts or pages, or have to add anything to the theme.
Ideally I would avoid any URLs that go into the wp-admin directory. End users don't belong in here.
I would strongly suggest referring to https://codex.wordpress.org/AJAX_in_Plugins#Ajax_on_the_Viewer-Facing_Side
You need to have a php script in your plugin directory that returns what you request, and you need to determine that url at run time for reference in your ajax. The above link gives an example for enqueuing and using wp_localize_script() to provide the url for your custom php script.
wp_enqueue_script( 'ajax-script',
plugins_url( '/js/my_query.js', __FILE__ ), array('jquery') );
// in JavaScript, object properties are accessed as
// ajax_object.ajax_url, ajax_object.we_value
wp_localize_script( 'ajax-script', 'ajax_object',
array( 'ajax_url' => plugins_url( '/php/myapi.php' ));
Your javascript file will be included on every page and will listen for events on the page which require a block of HTML, as you've described it.
Your file myapi.php then needs to take a request, probably using a query string, get the appropriate content from the wordpress api, and respond with said content, which your javascript will put into place.
To have access to the wordpress api as well though, you have two options:
Force wordpress to run starting with your file, by including wp-load.php. This is probably not the cleanest way.
Set up a custom page or slug to direct to your plugin.
I would advise the second option, and advise a slug, in which case you may find this post helpful: wp_rewrite in a WordPress Plugin
From Jason's comment, based on the link above:
The rewrite rules are mentioned a lot, but are really a distraction -
they just help to make URLs look more "friendly", which was not an
objective here. The key is: register a custom GET parameter; look for
that parameter early in the page rendering process; if you find the
parameter is set, then output/echo stuff and die(). There are a
number of hooks that can be used to look at the parameters, chosen
dependin on how much you want WP to set up and process first.
We have a wordpress website that does marketing display, but now we want to allow a customer to submit an email and selection to a separate website with a landing page that will handle the backend DB work and finish them in the other website.
Something like,
www.ourmarket.com/getdata (on Submit button click GETS to...)
www.ouradminsite/landingpage.aspx (which processes the data that the use will not see then...)
www.ouradminsite/login.aspx (where the user can now login)
I am not familiar with WP at all, but I was able to create a page with a form that has the textbox/combobox I need.
I thought it would be something simple, but somehow it seems not. I read about AJAX and doing something in functions.php and creating a custom .js file, but when working on the marketing site I find no way to add this type of function in.
My fall back is to have the WP page just have a link to a generic landing page where they enter data, but it would be visually jarring to the customer unless I duplicate the WP site for one page.
Is there an easy way to just tell WP to redirect to an external page with a GET?
UPDATE--------------
I like to think I'm making progress. I found a link that may have given me a good start. I added a function to the functions.php file located in my WP theme. It starts like this:
add_action("gform_post_submission_4", "set_post_content", 10, 2);
function set_post_content($entry, $form){
//Gravity Forms has validated the data
//Our Custom Form Submitted via PHP will go here
// Lets get the IDs of the relevant fields and prepare an email message
$message = print_r($entry, true);
// In case any of our lines are larger than 70 characters, we should use wordwrap()
$message = wordwrap($message, 70);
// Send
mail('myuser#mycompany.com', 'Getting the Gravity Form Field IDs', $message);
**wp_redirect("http://my.hearbuilder.com/hellomoto.aspx",301);**
}
From there I tried to edit the function to do that wp_redirect, just a simple one to start. This is added under the mail statement:
wp_redirect("http://my.hearbuilder.com/hellomoto.aspx",301);
From this link, when I fill out the form I can get the email, but the new page did not display. I added the exit; line and still got the same result, the page seems like it hangs.
The end result is that I need to have the new website landing page display (after it processes the data from the Wordpress form.
What am I still missing?
yes use wp_redirect()
if($_POST):
$textbox=$_POST['textboxname'];
$url= 'url'.'?custom=hello&textbox='.$textbox.'&anothervalue='.$anothervalue;
wp_redirect($url);
exit;
endif;
you can easily add the variables to the string as needed. The easiest way to control the url properly is to post the information to the same page , catch the post and redirect (place before get_header call or any output has started)
The other way is php Curl which is more difficult esp when dealing with .asp pages, but if you have access to the other server it makes figuring it out easier!
the RSS feed of annuncistar.it isn't valid because the "&" char is not allowed in RSS feeds.
In order to solve that issue I've added a WordPress filter in my functions.php file.
function mp_permalink($permalink) {
$url = str_replace("&", "&", $permalink);
return $url;
}
add_filter('the_permalink_rss', 'mp_permalink');
Unfortunately this function doesn't work. What could the reason be?
Your feed URL seems to have Google Analytics tracking variables (utm_source, etc.) appended to it. Normally, a WordPress feed URL looks as simple as (to take mine as an example):
http://gothick.org.uk/feed
However, with Analytics tracking variables, it looks something like this:
http://gothick.org.uk/?utm_source=source&utm_medium=medium&utm_term=term&utm_content=content&utm_campaign=campaign
So, I'm guessing that you have a plugin installed that is altering your feed URL to add these variables. Unfortunately, when it's being embedded in your RSS feed as the feed source, the ampersands in the URL aren't being escaped -- I'd guess this is a bug in the plugin.
I'd guess your filter isn't being run after the plugin changes the original feed. Whether that's because it's being run earlier in the filter chain or because the analytics plugin is targeting the feed URL at a different level, I'm not sure.
Either way, the solution will be to disable the analytics plugin, or at least the bit that alters the feed URL, or update it to a version that escapes the URL properly for use in the RSS feed XML.
I wonder if I could ask a Wordpress / RSS question I could't find an answer for around here,
Trying to syndicate posts via RSS in Wordpress using the FeedWordpress plugin as an RSS aggregator, each post in the original blog includes five custom fields that are important for its Theme functionality (the original and syndicating / receiving blog using the same theme).
The original RSS2 feed doesn't include these custom fields apart from one, being enclosure, that is defined in the default rss feed template (function in WP rss_enclosure).
This is written in the original feed such as:
<enclosure url="http://www.samplevideourl.flv" length="18554755" type="video/x-flv" />
Tried to add the rest of the custom fields modifying the rss2-feed.php template so they show at the end of each segment in the current RSS2 feed, now they are included as for example:
...
<ratings_average>0</ratings_average>
<views>5</views>
</item>
However, if I update the syndicated posts, or delete the posts and fetch the modified feed again with feedwordpress, none of these show in the syndicated posts.
Is there a way to include these custom fields so they are recognized by feedwordpress?
Basically need to syndicate the same format of the post as the original including all its custom fields.
Many Thanks
Carlos
There is a thread that covers this: https://wordpress.stackexchange.com/questions/3801/add-custom-fields-to-custom-post-type-rss
I've condensed the answers there to reflect the later improvements (thanks MikeSchinkel, prettyboymp and Acts7).
Add this to your theme's functions.php:
/* IN ORDER TO VALIDATE you must add namespace */
add_action('rss2_ns', 'my_rss2_ns');
function my_rss2_ns(){
echo 'xmlns:mycustomfields="'. get_bloginfo('wpurl').'"'."\n";
}
add_action('rss2_item', 'yoursite_rss2_item');
function yoursite_rss2_item() {
if (get_post_type()=='my_custom_post_type') {
$fields = array( 'field1', 'field2', 'field3' );
$post_id = get_the_ID();
foreach($fields as $field)
if ($value = get_post_meta($post_id,$field,true))
echo "<mycustomfields:{$field}>{$value}</mycustomfields:{$field}>\n";
}
}
This will add all custom field names and values to the site's main feed.
Note, for custom fields with more than one value, a modification is necessary as the above will only work for single value fields, not arrays.
So,
On your Master site (where you are syndicating FROM) you add the above function.
On the Slave site (where you are syndicating TO), assuming you have FeedWordPress installed, go to "SYNDICATION" ->
Click on the name of the RSS feed
Go to Custom Feed Settings and plug in the pieces
I need to add an image to each page in WordPress.
I don't wish to insert it using the WYSIWYG editor, I just need the url as a custom field, which I later use in the template.
I tried using the CFI plugin (Custom Field Images), and I hacked my way into getting it to work with the rest of my plugins, but then I moved the site to the production server and CFI just didn't work for some reason.
I can't seem to find any other plugin that just lets you pick an image from the library and add it as a custom field.
I've downgraded to the point where I'm willing to manually enter all the URLs into each and every page. but before I do, I thought I'd check here.
Can anyone tell me what's the easiest, best way to add images as custom fields in WordPress (2.7.1 if it matters)?
In our WordPress template, each post generally only has one image 'attached', which is displayed outside the posts' (textual) content.
I simply upload the file using the edit posts' media uploader, never insert it into the post like JoshJordan above, then retrieve the image using a bit of code in the right place in my template file.
This would also work if you're using more than one image in your post, eg. in your post content. As long as you keep the image used as the 'main' post image as the first image (remember you can re-order images in your posts' image library by dragging them up and down), you're easily able to call it anywhere in your template file by using something like this:
<?php
$img_size = 'thumbnail'; // use thumbnail, medium, large, original
$img_id = $wpdb->get_var("SELECT ID FROM $wpdb->posts where post_parent= $post->ID and (post_mime_type = 'image/jpeg' OR post_mime_type = 'image/gif') and post_type = 'attachment'");
$img_array = wp_get_attachment_image_src($img_id,$img_size,false);
echo '<img src="'.$img_array[0].'"' title="'.get_the_title().'" />';
?>
No need for copying and pasting image urls.
The template I have uses a manually-entered custom field for the splash image of each post. When I'm done writing my article, I upload an image, copy its URL from the upload tool, never insert it into my post, and then paste that URL into the "Image" custom field. Simple as pie and takes only seconds. Insignificant compared to the amount of time it takes me to write an article.
You can use the custom key value fields on posts as well. let's say you always give your images the key 'thumb'. you can then use this code to output them in your post as a thumbnail:
<?php
$values = get_post_custom_values("thumb");
echo “<img src=\”$values[0]\” class=\”thumb\”></a>”; ?>
Consider using Flutter it's a bit tricky to figure out at first, and has many really useful featured, including EIP (edit in place), and image handling.
After installing the plugin create a new "Write Panel", you'll figure it out from there. The plugin provides you with a rather intuitive GUI, which includes an image uploader. The template tags are very easy to use, I believe it's something like
<?php echo get_image('name_of_field'); ?>
I just had to build a site for a client that needed the same feature, I ended up using Flutter.
