I want to show my wordpress post into jquery mobile application... But so far i didnt got the success. I am using jquery.post() function but my response comes empty....
Request to the desired url goes well , status comes 200 ok but response coming is always blank :( Although the same post function & url is working fine in other php pages....
below is my code
function get_Time(cityCode,date){
jQuery.post(
"http://test.local/time/",
{ city: cityCode, date:date},
function (data){jQuery('#print_time').html(data);}
);
}
function _get_Time(response)
{
alert("response:"+response);
var time = new Array();
time = response.split('|')
jQuery("#print_time").html(time[0]);
}
Please give me some solution for showing my wordpress post (only text + links) content into my jquery mobile applicaton....
I am not sure about what you are going to do. It seems to me, like you want to retrieve a certain WordPress post content + additional information via Ajax, I think the easiest way to do it is the following:
Write a custom server-side PHP-Script (which possibly takes a WordPress Slug or ID)
Create a connection to the database in this script, get the post contents you want to have and return these as text or JSON to your JQuery mobile and use it
It might work in a way like this (not tested):
include ‘path-to-wp-directory/wp-blog-header.php’;
$post_id=0;
if(isset($_REQUEST['post_id'])) {
$post_id=intval($_REQUEST['post_id']);
}
global $wpdb;
$post_content = $wpdb->get_var("SELECT post_content FROM $wpdb->posts WHERE post_id=".$post_id." AND post_status='publish'";
echo $post_content;
This is only possible if you have access to the server, of course. If you want to get Post Content from an external WordPress Blog, then you should consider using the RSS Feed.
The following article shows how to load WordPress functions in an external PHP Script, which also might be useful: http://www.bloggingtips.com/2009/01/25/use-wordpress-functions-externally/

Using the Avada theme's form builder functionality, I’m attempting to use the “Send to URL” option to POST the form and then run an api call in a plugin I’ve written.
I was thinking I could set the “Send to URL” value to /wp-admin/admin-post.php and add a hidden field to the form named “action” with a value of “make_api_call” to get it to run the code in my plugin set up like so:
add_action('admin_post_make_api_call', 'make_api_call');
function make_api_call()
{
//todo: make the api call
wp_redirect(‘another-page’);
}
However, this does not work and returns this from the server: {"status":"error","info":"url_failed"}
What I want to do is to POST the form to admin-post.php, have my plugin run code when it POSTs, and then redirect to another page.
I've checked the documentation for the AVADA theme and it only says that you can specify a url to post to but doesn't give any additional details.
So I eventually got something to work, and I'm not knowledgeable or experienced enough with WordPress development to know if it is the "right" way, but it works well.
I realized that using the "Send to Url" option on the Avada form, it was POSTing the form to the admin-ajax.php file. There's plenty of documentation on that and I was able to partially make that work but I was not able to make it fit my use case b/c even though there is a way to configure the Avada form to redirect to a different URL on success I couldn't append parameters to that URL based on the return value from admin-ajax.php.
For future reference, here's what I was able to make work but not fit my use case by having the Avada form submission set to Send to Url. (I'm recreating this and some of it's from memory since I went with a different solution, so it may not be 100% runnable.)
The way admin-ajax works is all requests to admin-ajax.php are eventually handled by a WordPress action (filter?) like so:
add_action( 'wp_ajax_my_action', 'my_function' );
In the above, my_action is what you've set as the form's action by creating a hidden input element on your html form named action and setting it's value to "my_action". The my_function argument is the name of the function you want to run when the action happens.
add_action( 'wp_ajax_my_action', 'my_function' );
function my_function(){
//do stuff
}
Watching the request in Chrome's dev tools, I could see the action the form was setting was fusion_form_submit_form_to_url.
So ended up with this:
add_action( 'wp_ajax_fusion_form_submit_form_to_url', 'my_function' );
function my_function(){
//do stuff
}
You can see that the url you enter in the Form Submission URL field gets passed to admin-ajax as fusionAction. Whether the Avada theme does something additional with that - I don't know but you could use it to control the logic that gets executed in my_function. I suspect there's an action in the Avada form that works similar to the wp_ajax_ WordPress action but by the time I got this far I realized this wasn't going to work so I pivoted to the actual solution, below.
All of that worked okay but you can't redirect out of a call to admin-ajax.php unless you do it on the client side and I didn't want to dive into that.
What I was able to make work was configuring the Avada form to do a traditional HTTP POST. I added a hidden input element on the Avada form with a name of formName and the value set to the name of the form I wanted to handle.
In my plugin code, I hooked into the WordPress init action as in the code sample below, and then customized the logic to be executed based on which formName was sent in.
add_action('init', 'callback_function');
function callback_function()
{
if (isset($_POST['formName'])) {
$form = $_POST['formName']; //from the hidden input element "formName"
//there is a call to wp_redirect in each case
switch ($form) {
case 'form1':
process_form_1();
break;
case 'form2':
process_form_1();
break;
default:
# code...
break;
}
//without this "exit" you will get errors similar to "headers already sent"
exit;
}
}
This allowed me to run the code I needed to run based on what form was submitted, and redirect to the correct place afterward.
I'm developing a plugin that creates 2 pages: one listing page and one details page.
I don't use custom types. I have created a table into the database where I save the company details and also a slug for the details page.
It's working properly but I have a problem with the URLs. They are not pretty.
On the listing page I use this code to create the link:
<?php echo stripslashes($value->company_name); ?>
The generated link looks like this:
https://www.website.com/company/details/?companyname=new-company-name
I use the query because I need it on the details page, where I use this code:
$company_slug = $_GET['companyname'];
$company_details = $wpdb->get_row("SELECT * FROM $table_company WHERE company_slug = '$company_slug'");
This is how I retrieve the company details from sql and it also works just fine.
I have created manually in Wordpress the details page.
The problem is that I want the details URL to look pretty, like this:
https://www.website.com/company/details/new-company-name/
Generating it like this it's easy but when I click, I get a 404, since the query from URL is missing.
I was thinking it's easy to create directly the pretty URL and on the details page to parse the URL and get the company slug. It didn't work. I get a 404 maybe because the page doesn't physically exist.
So, I've done some research about URL rewrite and I have found some examples but none worked.
I have found tried this code also:
add_filter('query_vars', function($vars) {
$vars[] = "companyname";
return $vars;
});
function custom_rewrite_rule() {
add_rewrite_rule('^companyname/?([^/]*)/?','company/details/?companyname=$matches[1]','top');
}
add_action('init', 'custom_rewrite_rule', 10, 0);
I've read that I shouldn't use matches if I use a custom URL instead of index.php, so I have also tried without matches:
add_rewrite_rule('^companyname/?([^/]*)/?','company/details/?companyname=$1','top');
No results. If course, after every change I have saved again the permalinks.
This should be an easy task but somehow it doesn't work.
https://developer.wordpress.org/reference/functions/add_rewrite_rule/
Does anyone of you know how can I make this work?
Thank you.

I am assuming that the details page you created has the slug company/details. Here's what you need to do to make it work-
1. Add the custom rewrite rules in functions.php file:
function theme_custom_rewrites() {
add_rewrite_tag("%companyname%", "([a-z0-9\-_]+)");
add_rewrite_rule('^company/details/([a-z0-9\-_]+)/?$', 'index.php?pagename=company/details&companyname=$matches[1]', 'top');
}
add_action('init', 'theme_custom_rewrites');
It registers a new rewrite tag/query var named companyname to be used later and registers a custom rewrite rule for the specific URL structure you want (/company/details/company_name).
2. Get the company name on the template file and use it: After you have added the above code and saved the permalinks, you can get the companyname just by using the get_query_var() function.
$companyname = get_query_var( 'companyname' );
Hope it helps. Thanks.
Thank you very much for your fast reply. It worked.
Of course, I had to change the link on the listing page to:
<?php echo stripslashes($value->company_name); ?>
I have removed the query from the link and it looks like this now:
https://www.website.com/company/details/new-company-name/
What I don't understand, is how does WP know which is the query, since I removed it from the link.
I can see the same data if I access
https://www.website.com/company/details/?companyname=new-company-name
or
https://www.website.com/company/details/new-company-name/
But, basically, this part (?companyname=) doesn't exist anymore in the link, since I changed it.
I have no query now in my plugin, but somehow everything works properly. :)
I did not declare it somewhere. It's completely gone and it works.
How does this code know that the query exists and it's retrieving the slug from the database?
$companyname = get_query_var( 'companyname' );
I only have this code now:
<?php echo stripslashes($value->company_name); ?>
So, no query in URL.
Thank you for your time.

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!
I'm trying to have custom variables in my URL for Wordpress site. I have read up as much as I could find on the subject and so far have the following in my functions page:
function add_query_vars($aVars) {
$aVars[] = "mrdrct";
return $aVars;
}
// hook add_query_vars function into query_vars
add_filter('query_vars', 'add_query_vars');
And the following on my header page:
if(isset($wp_query->query_vars['mrdrct'])) {
$mVar = $wp_query->query_vars['mrdrct'];
echo "variable is $mVar <br />";
}
Just to test out if things are being passed correctly and they are. However, when I use a link with the url variable in it - say www.mydomain.com/?mrdrct=myVarable - I am not directed to my homepage of my Wordpress site which is set to a static page with a template on it - I am instead directed to a page with my latest posts on it. I cannot figure out why this is happening - any ideas? Hopefully I've explained this well enough.
Thanks.
When WP sees a query string (? after the URL) it will attempt to display matching posts using it's rewrite rules. If no posts match it will show a 404 error - I would guess you do not have a 404.php file, so WP is showing the default which is index.php (see the Wordpress Template Hierarchy for more details on that).
I'm not 100% sure what you want to achieve, but I'd suggest that you need to look at changing the query when $wp_query->query_vars['mrdrct'] is set. See the WP Codex for query_posts() for a good place to start, if you are not already familier with it.
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.
