I looked around here and by search engine, but unfortunately I couldn't find a solution for myself.
So, I now ask assistance with a function that I need to customize for the Contact Form 7 WordPress plugin. The function was from another question.
In a drop-down menu (select) I need two details (workshop name and date) in one option field. Both details come from the same post of a custom post type. The first detail is a post_title, the second is a custom-field from Meta-Box plugin.
The following function works in principle, but it only returns the one or the other detail. Probably the solution is within the foreach construct. But I don't know how it works.
I would be very grateful for support!
[UPDATE 2018-08-12]
After further research, I've found the solution at this post and changed the function accordingly.
The solution should look like this:
<select>
<option value="workshop name – date">workshop name – date</option>
...
</select>
This is the function:
add_filter( 'wpcf7_form_tag', 'dynamic_field_choose_workshop', 10, 2);
function dynamic_field_choose_workshop ( $tag, $unused ) {
if ( $tag['name'] != 'workshop' )
return $tag;
$args = array (
'post_type' => 'workshop',
'post_status' => 'publish',
'orderby' => 'name',
'order' => 'ASC',
'numberposts' => - 1,
);
$custom_posts = get_posts($args);
if ( ! $custom_posts )
return $tag;
foreach ( $custom_posts as $custom_post ) {
$ID = $custom_post->ID;
$tag['values'][] = $custom_post->post_title . ' - ' . rwmb_get_value('workshop_meta_boxes_date', '', $ID);
$tag['raw_values'][] = $custom_post->post_title . ' - ' . rwmb_get_value('workshop_meta_boxes_date', '', $ID);
$tag['labels'][] = $custom_post->post_title . ' - ' . rwmb_get_value('workshop_meta_boxes_date', '', $ID);
}
return $tag;
}
There is CF7 extension that will do this for you. Checkout the Smart Grid-Layout for CF7, it introduces a new tag called dynamic_dropdown. This is is what you want to use. The dynamic_dropdown creates a select field and allows you to populate the field options using either a taxonomy, titles of a post type, or a filter. You want to use the filter option to actually construct the options as per your requirement. The tag popup window is self explanatory, however if you get stuck post a comment below and I'll give you some more tips.
Using the following dynamic_dropdown tag,
[dynamic_select workshop-date-select class:select2 "source:filter"]
it creates a <select name="workshop-date-select"> dropdown field which will be converted into a select2 jquery field on the front end, and its values dynamically created using the following function placed in the functions.php file,
add_filter('cf7sg_dynamic_dropdown_custom_options', 'filter_options',10,3);
function filter_options($options, $field_name, $form_key){
/*first we verify if this is the right field from the right form
in case multiple forms with similar fieldd exiss.
the $form_key is a unique key exposed by the Smart Grid-layout plugin
instead of using form IDs to make forms and code more portable across servers.*/
if($form_key != 'my-form' && $field_name != 'workshop-date-select') return $options;
$options = array();
//load your options programmatically, as $value=>$name pairs.
$args = array (
'post_type' => 'workshop',
'post_status' => 'publish',
'orderby' => 'name',
'order' => 'ASC',
'numberposts' => - 1,
);
$workshops = get_posts( $args );
foreach($workshops as $workshop){
$val = $workshop->post_title . ' - ' . rwmb_get_value('workshop_meta_boxes_date', '', $workshop->ID);
$options[$val]=$val;
}
return $options;
}
this will create the desired dropdown select field in the front end.
NOTE of CAUTION: I would populate the option values as the workshop post ID rather than the same text as the option label. When the form is submitted the value of the post ID can be used to populate the notification email with the desired workshop title and date. This gives more flexibility to expand the reported information in the future.

I have an odd request, i'm not sure if this is even possible. But i'll try to work out the process below, and if anyone can help me work this out that would be amazing!
Ideally the process is as follows:
Admin goes to parent options page, within the options page there is a repeater field, called add new company. This will just be a field with a title.
Admin fills in field and presses save. This will generate a sub options page with that name, within the options field, there will be a set of fields like logo, a colour picker and some text fields (these could be a set of fields from within ACF if thats possible).
Also when this original Repeater Field is made/saved a set of pages is generated from a set of templates. Essentially using the name from the repeater field to be the main page title for the top level page and all the sub pages below are just dynamically generated. They don't need to have anything different about them, they just need to generate from a set of page templates. It needs to be able to associate with the newly generated company bits from the sub options field.
This will then essentially give the admin a new set of pages which will use the new options logo / colours etc. It would almost need to generate a new set of templates based off the master templates to dynamically make sure it picked up the correct information from the sub options page.
I'm not sure if this is possible, I have seen it work elsewhere on another job I have worked on (not exactly the same as the above but similar), but I can't work out the process to make it work sadly, as I have a horrid feeling that there is some complex bits within the database going on to do the duplication dynamically.
My other option is to run everything as a WordPress Multisite but I was trying to avoid that if possible on this occasion, but I may have to use Multisite to achieve the above.
If anyone can help me work this out that would be amazing!
Thanks in advance for any help :)
You should be able to plug into the save_post action and create new subpages from there.
add_action( 'save_post', 'create_sub_pages' ); //Plug into save_post action
//Function create sub_pages
function create_sub_pages($post_ID) {
//Repeater field name
$repeater_field_array = get_field('repeater_field_name');
//Loops through all of the items in the repeater field
foreach($repeater_field_array as $key => $value) {
//Check to see if there is already a sub page with that post name
$child_pages = get_pages(array( 'child_of' => $post_ID ));
$child_page_exists = false;
foreach($child_pages as $pages) {
if ($pages->post_title === $key) {
$child_page_exists = true;
}
}
//If not, set up the creation of the new post
if ($child_page_exists === false) {
$new_page_title = esc_html__( $key );
$new_page_content = '';
$new_page = array(
'post_type' => 'page',
'post_date' => esc_attr( date('Y-m-d H:i:s', time()) ),
'post_date_gmt' => esc_attr( date('Y-m-d H:i:s', time()) ),
'post_title' => esc_attr( $new_page_title ),
'post_name' => sanitize_title( $new_page_title ), //This could from the sub_field in the repeater
'post_content' => $new_page_content,
'post_status' => 'publish',
'post_parent' => $post_ID,
'menu_order' => $new_page_order
);
$new_page_id = wp_insert_post( $new_page );
update_post_meta( $new_page_id, '_wp_page_template', $value );
}
}
}
Again, this is just a spitball since there was not much code to review, but it could help you get going in the right direction.
I am trying to dynamically populate two dropdown fields in a Gravity Forms form. The first field dynamically populates with the terms available in a custom post type. I want the second dynamically populated field to contain the list of all post titles within the custom post type AND have those titles filtered by the term selected in the previous dropdown. Is it possible to get the value of a dropdown within Gravity Forms and pass that value as a parameter in $args to use the get_posts($args) function?
I started using the following tutorial as a guide. https://docs.gravityforms.com/dynamically-populating-drop-down-fields/
add_filter( 'gform_pre_render_3', 'populate_procedures' );
add_filter( 'gform_pre_validation_3', 'populate_procedures' );
add_filter( 'gform_pre_submission_filter_3', 'populate_procedures' );
add_filter( 'gform_admin_pre_render_3', 'populate_procedures' );
function populate_procedures( $form ) {
// Procedure Category Dropdown
foreach ( $form['fields'] as &$field ) {
The first field. The following code populates a dropdown field containing a list of all of the terms within a custom post type (procedure):
if ( $field->type != 'select' || strpos( $field->cssClass, 'populate_procedure_categories' ) === false ) {
continue;
}
$terms = get_terms( array(
'taxonomy' => 'procedure_category',
'orderby' => 'name',
'order' => 'ASC',
) );
// you can add additional parameters here to alter the posts that are retrieved
// more info: http://codex.wordpress.org/Template_Tags/get_posts
//$posts = get_posts( 'post_type=procedure&numberposts=-1&post_status=publish' );
$choices = array();
foreach ( $terms as $term ) {
$choices[] = array( 'text' => $term->name, 'value' => $term->name );
}
// update 'Select a Post' to whatever you'd like the instructive option to be
$field->placeholder = 'Select Procedure Category';
$field->choices = $choices;
The second field. The following code dynamically populates the field with all of the the post titles of the custom post type (procedure). I want to filter these results based upon the value selected above.
if ( $field->type != 'select' || strpos( $field->cssClass, 'populate_procedures' ) === false ) {
continue;
}
$args = array(
'post_status' => 'publish',
'post_type' => 'procedure',
'procedure_category' => 'cardiovascular',
);
$posts = get_posts( $args );
$choices = array();
foreach ( $posts as $post ) {
$choices[] = array( 'text' => $post->post_title, 'value' => $post->post_title );
}
// update 'Select a Post' to whatever you'd like the instructive option to be
$field->placeholder = 'Select Procedure';
$field->choices = $choices;
}
return $form;
}
The second dynamically populated field successfully pulls in the filtered list of post titles based on the $args if I explicitly listed the term (in the example above I used 'cardiovascular'). What I am wondering is if there is a way to grab the value of the previous field and use that to filter the results of the second field (without having to reload the page). Any ideas? Does Gravity Forms have a functionality like this built in?
Using this method, you would need to use multiple pages and add the second Drop Down field to the second page on the form. Then, when the user submits the first page, you can access the value of the first Drop Down from the $_POST. Gravity Forms has a helper method for doing this called rgpost(). Here's what your $args might look like:
$args = array(
'post_status' => 'publish',
'post_type' => 'procedure',
'procedure_category' => rgpost( 'input_FIELDID' ),
);
Replace FIELDID with the field ID of your first Drop Down.
With that said, if you want to accomplish this without having to touch any code, try Gravity Forms Populate Anything.

I am using Event Espresso with WordPress.
May u help me out in further query modification?
Hope you will :)
I want to use meta_query to list events on page.
Somewhat like below code.
$atts = array(
'title' => NULL,
'limit' => 10,
'css_class' => NULL,
'show_expired' => FALSE,
'month' => NULL,
'category_slug' => NULL,
'order_by' => 'start_date',
//'order_by' => 'end_date',
'sort' => 'DESC',
'meta_query' => array(
array(
'key' => 'start_date',
'value' => '2017-01-08 08:00:00',
'type' => 'DATETIME',
'compare' => '>=',
),
)
);
I want to implement search functionality for Event Espresso and i have those fields:
State - Dropdown (How to list all state? May be Venue)
Category - Dropdown
Start Date - Datepicker
End Date - Datepicker
Keyword - input
On submit those values will be submitted and based on those , i will get filtered events that are related with those values.
So how to implement this?
Please help.
Thanks in Advance
A slightly delayed response to this...
First, this depends on the version of EE you're using. They support both EE3 and EE4. I use EE4, so any reference to code I make is specific to version 4.
In order to create an events archive with a filtering functionality, you'd need to use the EE events archive. EE uses custom database tables and a lot of different post types to achieve what you see, so creating a simple archive with these filters won't work very well. Very little is stored in the _posts and _postmeta tables and you need to get post meta from related post types and tables that aren't laid out like WP_Query likes. They have a shortcode for the events list, which is laid out here and has a lot of the filters you're looking for, but no search functionality.
Their support forum has a lot of snippets and such created by their staff and there's a (long) related post about formatting the events archive page here. You'll also need to go through this documentation to see about their custom methods and hooks.
You could copy over and modify the archive templates they describe in a child theme to add search functionality to the top of the page. This would allow you to directly override the archive. You'll need to make use of some fancy filters, which are covered pretty clearly over on WPMU Dev.
The pieces of information you're looking for for filtering are here, minus keyword:
<?php
if( have_posts() ){
while ( have_posts() ){ the_post(); // enter the WordPress loop
$id = get_the_ID(); // get the ID of the current post in the loop, post ID = EVT_ID
$terms = get_the_terms( $id, 'espresso_event_categories' ); // get the event categories for the current post
if ( $terms && ! is_wp_error( $terms ) ) {
$cats = array();
foreach ( $terms as $term ) {
// do something
}
}
$event = EEM_Event::instance()->get_one_by_ID( $id ); // get the event OBJECT using EE's existing method
$venue = $event->venue(); // get the venue object for the current event
$state = $venue instanceof EE_Venue ? $venue->state_abbrev(); // get the event venue's state, but you can use state_name() to get the full name
// using the event to get the first and last date for the entire event. Sub $datetime for $event to do it per datetime
$start_date = $event->start_date('j M Y');
$end_date = $event->end_date('j M Y');
$start_time = $event->start_time(get_option('time_format'));
$end_time = $event->end_time(get_option('time_format'));
?>
<!-- Do some awesome layout stuff here -->
<?php
}
}
espresso_pagination();
?>
This will give you the meta for each post within the loop as variables, but you may want to pull them into pre_get_posts. You can just as easily create an array of $events and then filter it using the variables.
I'm not sure what your exact needs are regarding keyword. Do you mean tags? Title keywords? Description search? You'll need to narrow down exactly what you need this to do in order to write a function for it.
I'm developing a social network with Buddypress, I created a RSS plugin to pull the RSS feed from the specified websites.
Everything is working, except when the RSS is posted to the activity stream. When I create the activity content to print a link, I set the link target to "_new" to open it in a new page.
Here's the code:
function wprss_add_to_activity_feed($item, $inserted_ID) {
$permalink = $item->get_permalink();
$title = $item->get_title();
$admin = get_user_by('login', 'admin');
# Generates the link
$activity_action = sprintf( __( '%s published a new RSS link: %s - ', 'buddypress'), bp_core_get_userlink( $admin->ID ), '' . attribute_escape( wprss_limit_rss_title_chars($title) ) . '');
/* Record this in activity streams */
bp_activity_add( array(
'user_id' => $admin->ID,
'item_id' => $inserted_ID,
'action' => $activity_action,
'component' => 'rss',
'primary_link' => $permalink,
'type' => 'activity_update',
'hide_sitewide' => false
));
}
It should come up with something like that:
Test
But it prints like that:
Test
Why is this happening?
The 'target' attribute is probably getting stripped by BuddyPress's implementation of the kses filters. You can whitelist the attribute as follows:
function se16329156_whitelist_target_in_activity_action( $allowedtags ) {
$allowedtags['a']['target'] = array();
return $allowedtags;
}
add_filter( 'bp_activity_allowed_tags', 'se16329156_whitelist_target_in_activity_action' );
This probably won't retroactively fix the issue for existing activity items - it's likely that they had the offending attribute stripped before being stored in the database. But it should help for future items.
In Wordpress it's possible to create own WP Querys for the loop. An example is this:
$my_query = new WP_Query(array('post_parent' => 3, 'post_type' => 'page'));
Another example is this:
$my_query = new WP_Query(array('cat' => 1, 'post_type' => 'post'));
I want a loop that presents pages AND posts from the same loop.
Now to my question. Is it possible to combine these two objects into one? If it is, how? I'm NOT interested in creating two different loops.
In case you don't want to do it with SQL, this is how I did my search page.
Basic problem: When doing a meta_query, wordpress thinks I want the condition to be joined with "AND" instead of "OR".
So Wordpress looks for a page with title/content = "myContent" AND the aioseop_keyword "myContent". This (in my case) lead to zero results, despite there was a page with matching SEO keyword.
To get around this, I make two queries. Sounds simple, BUT: the Loop didn't want to recognize the posts, despite there are posts in the $post object. I found this solution after taking a look on the have_posts() function : it refers to other variables than just the $post object.
$term = get_search_query(); // same as $_GET['s']
# the normal search:
$wordpress_keyword_search =& new WP_Query(array(
's' => $term,
'showposts' => -1
));
# now push already found post IDs to an array, so we can exclude them from the meta search.
foreach ($wordpress_keyword_search->posts as $post_)
$exclusion[] = $post_->ID;
# now do the meta query search
$aioseop_keyword_search =& new WP_Query(array(
'post__not_in' => $exclusion,
'post_type' => 'any',
'showposts' => -1,
'meta_query' => array(
array(
'key' => '_aioseop_keywords',
'value' => $term,
'compare' => 'LIKE',
)
)
));
# merge the two array posts.
# post_count and found_posts must be added together also.
# otherwise have_posts() returns false.
# see: http://core.trac.wordpress.org/browser/tags/3.6.1/wp-includes/query.php#L2886
$wordpress_keyword_search->posts = array_merge($wordpress_keyword_search->posts, $aioseop_keyword_search->posts );
$wordpress_keyword_search->found_posts = $wordpress_keyword_search->found_posts + $aioseop_keyword_search->found_posts;
$wordpress_keyword_search->post_count = $wordpress_keyword_search->post_count + $aioseop_keyword_search->post_count;
Then use this in a simple loop:
if ($wordpress_keyword_search->have_posts()) {
while($wordpress_keyword_search->have_posts()) {
$wordpress_keyword_search->the_post();
# now you simply can:
the_title();
the_content();
}
} else {
echo '<p>Sorry, no posts found</p>';
}
what you want would translate to a WHERE ... OR ... condition or a UNION in SQL, eg.
SELECT * FROM posts WHERE (post_parent = 3 AND post_type = 'page')
OR (cat = 1 AND post_type = 'post')
or
SELECT * FROM posts WHERE post_parent = 3 AND post_type = 'page'
UNION
SELECT * FROM posts WHERE cat = 1 AND post_type = 'post'
from looking at the source and the way WP constructs SQL from WP_Query(), i don't think this is possible: there is no OR'ing nor UNION of query vars.
the only thing that comes to my mind is writing a plugin that implements the posts_where filter (applied to the WHERE clause of the query that returns the post array). you could call this plugin with your different WP Querys, and the plugin would get their WHERE parts and could OR them together.
