I am making front end admin for users to add/edit their posts. I already made post add form and it works, but edit form doesnt work.
functions.php
function add_new_post( $post_id )
{
if( $post_id == 'new' ) {
// Create a new post
$post = array(
'post_title' => $_POST["fields"]['field_52c810cb44c7a'],
'post_category' => array(4),
'post_status' => 'draft',
'post_type' => 'post'
);
// insert the post
$post_id = wp_insert_post( $post );
return $post_id;
}
else {
return $post_id;
}
}add_filter('acf/pre_save_post' , 'add_new_post' );
index.php
<div id="updateform-<?php the_ID(); ?>" class="collapse">
<?php
echo get_the_ID();
$args = array(
'post_id' => get_the_ID(), // post id to get field groups from and save data to
'field_groups' => array(31), // this will find the field groups for this post (post ID's of the acf post objects)
'form' => true, // set this to false to prevent the <form> tag from being created
'form_attributes' => array( // attributes will be added to the form element
'id' => 'post',
'class' => '',
'action' => get_permalink( get_the_ID() ),
'method' => 'post',
),
'return' => add_query_arg( 'updated', 'true', get_permalink() ), // return url
'html_before_fields' => '', // html inside form before fields
'html_after_fields' => '', // html inside form after fields
'submit_value' => 'Update', // value for submit field
'updated_message' => 'Post updated.', // default updated message. Can be false to show no message
);
acf_form( $args );
?>
</div>
For saving posts you should use save_post not pre_save_post.
Basically pre_save_post is used for new posts.
Use this below add_filter('save_post' , 'add_new_post');
I created plugins for that:
Forms actions
https://wordpress.org/plugins/forms-actions/
Add actions to yours ACF forms.
ACF Frontend display
https://wordpress.org/plugins/acf-frontend-display/
Display your ACF form on frontend
If by some chance you happen to be using Elementor Page Builder, you can do this by installing Advanced Widgets for Elementor. It comes with an ACF Form widget that you can just drag & drop anywhere into your site and configure your form through the UI (no coding required).

I've grabbed this code from the Advanced Custom Fields website to make an employee directory with a front-end ACF form. But I can't get it to produce a permalink that is the title employee name, which is the title of the post. It just produces a random number. Permalinks are set to Post Name Here is the code in my template file:
<?php while ( have_posts() ) : the_post(); ?>
<?php
acf_form(array(
'post_id' => 'new_post',
'post_title' => wp_strip_all_tags($_POST['acf']['field_624c65c9cc5da']), // Post Title ACF field key
'return' => '%post_url%',
'new_post' => array(
'post_type' => 'staff',
'post_status' => 'publish'
)
));
?>
<?php endwhile; ?>
And this is the code in my functions PHP file:
add_action('acf/save_post', 'my_save_post', 20);
function my_save_post($post_id){
// Get the data from a field
$new_title = get_field('staff_name', $post_id);
// Set the post data
$new_post = array(
'ID' => $post_id,
'post_title' => $new_title,
);
// Remove the hook to avoid infinite loop. Please make sure that it has
// the same priority (20)
remove_action('acf/save_post', 'my_save_post', 20);
// Update the post
wp_update_post( $new_post );
// Add the hook back
add_action('acf/save_post', 'my_save_post', 20);
}
This question makes me crazy for almost 2 weeks. I know I am not expert in Wordpress, so I am seeking for help here.
I have create a href that when user click it will go to new page.
Add Class2
This href post the Post id. Url display:
[http://localhost/dev6/create-class/?post=289][1]
create-class page:
At create-class page,I am using GET method to display post id from url
$post = $_GET['post'];
I have acf form in create-class page for create new post. In this form, there have dynamic select field but the select field not display any data.
<?php acf_form(array(
'post_id' => 'new_post',
'field_groups' => array(150),
'post_title' => false,
'post_content' => false,
'new_post' => array(
'post_type' => 'classes',
'post_status' => 'publish',
),
'return' => '%post_url%',
'submit_value' => 'Submit',
//'updated_message' => 'Course Submit!',
)); ?>
in my function.php I create function for dynamic select:
function acf_load_t_first_name2_field_choices($field) {
global $post;
//$post = $_GET['post'];
// reset choices
$field['choices'] = array();
// get the textarea value from options page without any formatting
$choices = get_field('t_first_name',$post->ID);
// loop through array and add to field 'choices'
if( is_array($choices) ) {
foreach( $choices as $choice ) {
$field['choices'][ $choice ] = $choice;
}
}
// return the field
return $field;
}
add_filter('acf/load_field/name=t_first_name2', 'acf_load_t_first_name2_field_choices');
Is there something wrong with my code?
I don't believe this will work in your create-class template:
$post = $_GET['post'];
You will need to set something like this up in your functions.php file:
function custom_query_vars_filter($vars) {
$vars[] .= 'post';
return $vars;
}
add_filter( 'query_vars', 'custom_query_vars_filter' );
Then, in your create-class template you can get the variable from the URL like this:
$post = get_query_var('post');
See if that gets you going in the right direction.
I use wordpress standard with the plugins "Advanced custom fields" and "custom_post_type ui". I created a post_type called deals and added some custom fields with it.
What I need to do now, is filter the results when accessing the rest api like this:
http://localhost:8000/wp-json/wp/v2/deals
Actually I only need the acf part of it. I dont care about the rest.
[{"id":29,"date":"2019-04-12T12:34:14","date_gmt":"2019-04-
12T12:34:14","guid":{"rendered":"http:\/\/localhost:8000\/?
post_type=deals&p=29"},"modified":"2019-04-
12T12:34:14","modified_gmt":"2019-04-12T12:34:14",
"slug":"test-title","status":"publish","type":"deals",
"link":"http:\/\/localhost:8000\/deal s\/test- title\/","template":"",
"meta":[],"tax-deals":[],"acf":{"title":"Title for Deals
Post","description":"","image":false,"date_start":"01.01.1970",
"date_end":"01.01.1970","category":"Kleidung"},"_links":{"self":
[{"href":"http:\/\/localhost:8000\/wp-json\/wp\/v2\/deals\/29"}],
"collection":[{"href":"http:\/\/localhost:8000\/wp-
json\/wp\/v2\/deals"}],"about":[{"href":"http:\/\/localhost:8000\/wp-
json\/wp\/v2\/types\/deals"}],"wp:attachment":
[{"href":"http:\/\/localhost:8000\/wp-json\/wp\/v2\/media?
parent=29"}],"wp:term":[{"taxonomy":"tax_deals","embeddable":true,
"href":"http:\/\/localhost:8000\/wp-json\/wp\/v2\/tax-deals?
post=29"}],"curies":
[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}},
I have already tried using
http://localhost:8000/wp-json/wp/v2/deals?search=id
to get the id or something, but response is empty.
Also this didnt work:
http://localhost:8000/wp-json/wp/v2/deals?id=28
Again empty response.
To summarize: I need to filter my custom post type on my custom fields by the "acf" attribute shown in my response json. How does it work?
EDIT: I already installed "WP REST Filter" but still dont know how to do it.
I suggest you to create a new API where you can customize the output. Take advantage of wordpress function register_rest_route() using this you can create an API from CPT and ACF in one ajax url. And you do not need to install anything.
Check how I get my instructor CPT and mycheckbox ACF.
// your ajaxurl will be: http://localhost/yoursite/wp-json/custom/v2/instructor/
add_action( 'rest_api_init', function () {
register_rest_route( 'custom/v2', '/instructor', array(
'methods' => 'GET',
'callback' => 'instructor_json_query',
));
});
// the callback function
function instructor_json_query(){
// args to get the instructor
$args = array(
'post_type' => 'instructor',
'posts_per_page' => -1,
'post_status' => 'publish',
'meta_query' => array(
array(
'key' => 'mycheckbox', // your acf key
'compare' => '=',
'value' => '1' // your acf value
)
)
);
$posts = get_posts($args);
// check if $post is empty
if ( empty( $posts ) ) {
return null;
}
// Store data inside $ins_data
$ins_data = array();
$i = 0;
foreach ( $posts as $post ) {
$ins_data[] = array( // you can ad anything here and as many as you want
'id' => $posts[$i]->ID,
'slug' => $posts[$i]->post_name,
'name' => $posts[$i]->post_title,
'imgurl' => get_the_post_thumbnail_url( $posts[$i]->ID, 'medium' ),
);
$i++;
}
// Returned Data
return $ins_data;
}
Then, you can use the link: http://localhost/yoursite/wp-json/custom/v2/instructor/ in your ajax url.
I am adding load more comments button in comments section. i want load function wp_list_comments using Ajax, function are loading but wp_list_comment not display in wordpress 4.3.16 version. How to solve this problem???
My code are is:
// maybe it isn't the best way to declare global $post variable, but it is simple and works perfectly!
add_action('wp_ajax_cloadmore', 'misha_comments_loadmore_handler');
add_action('wp_ajax_nopriv_cloadmore', 'misha_comments_loadmore_handler');
function misha_comments_loadmore_handler(){
global $post;
$post = get_post( $_POST['post_id'] );
setup_postdata( $post );
// actually we must copy the params from wp_list_comments() used in our theme
wp_list_comments( array(
'page' => $_POST['cpage'], // current comment page
'per_page' => get_option('comments_per_page'),
'style' => '<div>', // comments won't wrapped in this tag and it is awesome!
'short_ping' => true,
) );
die; // don't forget this thing if you don't want "0" to be displayed
}
Try this code.
add_action('wp_ajax_cloadmore', 'misha_comments_loadmore_handler');
add_action('wp_ajax_nopriv_cloadmore', 'misha_comments_loadmore_handler');
function misha_comments_loadmore_handler(){
$comments = get_comments(array(
'post_id' => $_POST['post_id'],
'status' => 'approve'
));
wp_list_comments(array(
'page' => $_POST['cpage'], // current comment page
'per_page' => get_option('comments_per_page'),
'style' => '<div>', // comments won't wrapped in this tag and it is awesome!
'short_ping' => true,
), $comments);
die; // don't forget this thing if you don't want "0" to be displayed
}
I have a form that collects data about a user's product and then creates a page in WordPress with
$my_post = array(
'post_content' => "My page content",
'post_title' => $product_title,
'post_name' => $product_title,
'post_type' => 'page', // must be 'page' to accept the 'page_template' below
'page_template' => "listing.php",
'post_status' => "publish"
);
$ID = wp_insert_post( $my_post );
$permalink = get_permalink($ID);
echo "<br />ID for new page is $ID, Permalink for new page is $permalink";
The form data is put into meta variables for the page ID and the listing.php template file pulls it out of there and builds the HTML to display the product page. This all works fine and I can see that the page meta variable, _wp_page_template, gets set correctly to the template file I specified, listing.php:
Now I want to create a second page from the same form data, this one displaying different parts of the data in a different way. So I've added a second block of code, starting at $my_cert below, that creates this second page and specifies a different template, certificate.php, that knows how to build the second version of the data.
$my_post = array(
'post_content' => "My page content",
'post_title' => $product_title,
'post_name' => $product_title,
'post_type' => 'page', // must be 'page' to accept the 'page_template' below
'page_template' => "listing.php",
'post_status' => "publish"
);
$ID = wp_insert_post( $my_post );
$permalink = get_permalink($ID);
echo "<br />ID for new page is $ID, Permalink for new page is $permalink";
$my_cert = array(
'post_content' => "My certificate", // post_content is required
'post_title' => "My certificate", // post_title is required
'post_name' => "My certificate",
'post_type' => 'page', // must be 'page' to accept the 'page_template' below
'page_template' => "certificate.php",
'post_status' => "publish"
);
$CERT_ID = wp_insert_post( $my_cert );
$cert_permalink = get_permalink($CERT_ID);
echo "<br />ID for new certificate is $CERT_ID, Permalink for new certificate is $cert_permalink";
But when I look in the meta data for the second page created, the template is set to "default" instead of certificate.php:
I know I've set up certificate.php correctly as a template (set /* Template Name: certificate */ at the top) because the Page Edit Template dropdown includes certificate:
So does anyone see why I can't create this second page with the template set to certificate.php?
Thanks
Are you sure your page template src for: certificate.php is: certificate.php? And not: templates/certificate.php or something like that. Look in your theme folder and be 100% of the page template path. Check your spelling or for typos in the page template path or name. It must be an exact match.
If you still have problems I would look into and debug the source code of: wp_insert_post()
if ( ! empty( $postarr['page_template'] ) && 'page' == $data['post_type'] ) {
$post->page_template = $postarr['page_template'];
$page_templates = wp_get_theme()->get_page_templates( $post );
if ( 'default' != $postarr['page_template'] && ! isset( $page_templates[ $postarr['page_template'] ] ) ) {
if ( $wp_error ) {
return new WP_Error('invalid_page_template', __('The page template is invalid.'));
}
update_post_meta( $post_ID, '_wp_page_template', 'default' );
} else {
update_post_meta( $post_ID, '_wp_page_template', $postarr['page_template'] );
}
}
So its probably this part that fails:
if ( 'default' != $postarr['page_template'] && ! isset( $page_templates[ $postarr['page_template'] ] ) )
Try to modify: wp-includes/post.php and go to the definition of: function wp_insert_post() on row: 2872. And add a new row on row: 3312 for debugging purposes.
echo '<pre>';
print_r( $page_templates );
echo '</pre>';
die();
Make sure your certificate.php is among those in that array. Remember to delete the debug code before continuing. This should give you some answers.
