I need to display the post value in drupal - drupal

$query = $this->database->select('users_field_data', 'u');
$query->innerJoin(
'group_content_field_data',
'gc',
"gc.entity_id = u.uid"
);
$query->leftJoin(
'opigno_learning_path_achievements',
'a',
'a.uid = u.uid'
);
echo $status = \Drupal::request()->query->get('status');
$query->condition('u.status',$status);
I have tried with this line after selecting on the dropdown and then click on the submit button but it is not working.

As stated in the docs, \Drupal::request()->query with get the query parameters, to get the post parameters use \Drupal::request()->request.
ie. change.
\Drupal::request()->query->get('status');
to
\Drupal::request()->request->get('status');

Wordpress Pod Relationshop field

Is it possible to display a template for a related pod?
$mypod = pods('custompage', 'page-slug');
$related_pod = $mypod->field('top_feature');
Now I want to call something like
$related_pod->template('FeatureTemplate');
I can't seem to find a solid answer in this docs, is this possible?
What you are trying to do will not work. The problem is that $related_pod is not an object of the Pods class, and therefore you can not call the method template() on it.
It is possible to use the ID of the related item to build a second Pods object for the related post, which we can then call the method template() on. Normally we wouldn't do this because we don't need to and its not the most performant way of working.
Here is how you can do this. IMPORTANT: this assumes that "top_feature" is a single select field, as it is in OP's case. This will not work for a multi-select field.
```
$mypod = pods( 'custompage', 'page-slug' );
$relationship_field = $mypod->field( 'top_feature' );
if ( $relationship_field ) {
//get ID of related item
//Depending on content type you may need to use, 'id', instead of 'ID'
$related_item_id = pods_v( 'ID', $relationship_field );
$related_pod = pods( 'name_of_related_pod', $related_item_id, true );
if ( is_a( $related_pod, 'Pods' && $related_pod->id() === $id ) ) {
$related_pod->template( 'FeatureTemplate' );
}
}
```

wordpress plugin creation get_post_meta

I am building my first plugin, and I am using as a reference the following link.
http://www.sitepoint.com/create-a-voting-plugin-for-wordpress/
and I am trying to underestand the following part of the code:
function voteme_addvote()
{
$results = '';
global $wpdb;
$post_ID = $_POST['postid'];
$votemecount = get_post_meta($post_ID, '_votemecount', true) != '' ? get_post_meta($post_ID, '_votemecount', true) : '0';
$votemecountNew = $votemecount + 1;
update_post_meta($post_ID, '_votemecount', $votemecountNew);
$results.='<div class="votescore" >'.$votemecountNew.'</div>';
// Return the String
die($results);
}
I run the code and it works, but I just dont understand the following:
What is "get_post_meta" doing?
Does it create a custom meta field, the same as add_post_meta?, if it doesnt why there is not an add_post_meta?
I checked the DB, and it looks like it is creating a custom meta field... so in that order what is the difference between get_post_meta and add_post_meta?
Thanks very much for helping me understand this.
The first time your code runs, get_post_meta returns '' so $votemecount is set to 0. The following update_post_meta creates the new meta field as documented below. Values that start with _ are not displayed (are hidden meta fields).
The function, update_post_meta(), updates the value of an existing meta key (custom field) for the specified post.
This may be used in place of add_post_meta() function. The first thing this function will do is make sure that $meta_key already exists on $post_id. If it does not, add_post_meta($post_id, $meta_key, $meta_value) is called instead and its result is returned.

WP Settings API save to multiple options

In the Wordpress Settings API, creating a new options page usually starts out with
register_setting('sample_options', 'my_option');
add_settings_section('section', 'Sample Options', 'callback1', 'page');
add_settings_field('name', 'Label', 'callback2', 'page', 'section');
In this simplified example, the data gets saved in the option my_option making the value of name accessible through
$option = get_option('my_option');
$name = $option['name']; // Got it
But what if the value of the name field is there not to place a new value but to update an already existing option that's not my_option like for example this_other_option? I guess what I'm really looking for is is it possible for one field to save to multiple options (my_option and this_other_option) while using the Settings API?
I suppose you could use a callback in register_setting. It would look something like the following:
<?php
register_setting('sample_options', 'my_option', 'my_sanitize_callback');
function my_sanitize_callback($value, $option) {
$value = mysql_real_escape_string($value);
update_option('my_other_option', $value);
return $value;
}
?>
You may have to tweak that a bit. I haven't tested it.

wordpress contact form 7 unique id

i am currently using contact form 7 for wordpress. i would like a unique id for every form filled in and sent.
i have had a look around the internet but cant find anything, although i did find the following:
http://contactform7.com/special-mail-tags/
would there be any easy way to make my own function to do something similar to the above tags? i would need it to be a function to go into my themes function file, so that plugin updates wont affect it.
Cheers Dan
[_serial_number] field is an auto-incremented form submission ID. You just have to have Flamingo plugin installed as well. See http://contactform7.com/special-mail-tags/
(It's the same link as in the question, I guess the field wasn't there when the question was asked).
To generate ID for the Contactform7 you need to hook the 'wpcf7_posted_data'.
However, to generate incremental ID you need to save the forms in database so you can retrieve which ID should be next on next Form submit. For this you will need CFDB plugin (https://cfdbplugin.com/).
If you dont want to put the code inside theme functions.php file, you can use this plugin instead: https://wordpress.org/plugins/add-actions-and-filters/
Example code:
function pk_generate_ID($formName, $fieldName) {
//Retrieve highest ID from all records for given form stored by CFDB, increment by 1 and return.
require_once(ABSPATH . 'wp-content/plugins/contact-form-7-to-database-extension/CFDBFormIterator.php');
$start = '001';
$exp = new CFDBFormIterator();
$atts = array();
$atts['show'] = $fieldName;
$atts['filter'] = "$fieldName>=$start&&$fieldName<999999999999"; //is_numeric() is not permitted by default for CFDB filter
$atts['limit'] = '1';
$atts['orderby'] = "$fieldName DESC";
$atts['unbuffered'] = 'true';
$exp->export($formName, $atts);
$found = $start;
while ($row = $exp->nextRow()) {
$row2 = $row[$fieldName];
$row2 += 1;
$found = max($found,$row2);
}
return $found;
}
function pk_modify_data( $posted_data){
$formName = 'Form1'; // change this to your form's name
$fieldName = 'ID-1'; // change this to your field ID name
//Get title of the form from private property.
$cf_sub = (array) WPCF7_Submission::get_instance();
$cf = (array) $cf_sub["\0WPCF7_Submission\0contact_form"];
$title = (string) $cf["\0WPCF7_ContactForm\0title"];
if ( $posted_data && $title == $formName) ) { //formName match
$posted_data[$fieldName] = pk_generate_ID($formName, $fieldName);
}
return $posted_data;
}
add_filter('wpcf7_posted_data', 'pk_modify_data');

Setting location data programmatically

I'm stuck on a problem that I've researched for several days with no luck and the answers here are usually spot on.
I have custom module code that adds a node from form supplied data:
$edit = array();
$edit['uid'] = $user->id;
$edit['name'] = $user->name;
$edit['status'] = 1;
$edit['taxonomy'] = array($term_id);
$edit['title'] = $Title;
$edit['body'] = $body;
etc...
and then saved with:
node_invoke_nodeapi($edit, $nType);
node_validate($edit);
if ($errors = form_get_errors()) {
print_r($errors);
}
$node = node_submit($edit);
node_save($node);
This all works perfectly. But I'm trying to add location data to each node based on a supplied (sanitized) zip field.
I have gmap and location modules installed and working. When I add the zip directly using the drupal content editor it all works. Even the views gmap. So i know versions and mods are all correct.
I've used this:
$location = array(
'country' => 'US',
'postal_code' => $zip,
);
$locationID = location_save($location);
and this:
$location['country'] = "US";
$location['postal_code'] = $zip;
$locationID = location_save($location);
with and without the country element.
And then in the node data init section (above) this:
$edit->locations[0]['lid'] = $locationID;
or
if($locationID) $edit['field_location'][0]['lid'] = $locationID;
or
if($locationID) $edit['location'][0]['lid'] = $locationID;
But none of this works. The submit will go through ok actually but no location data is saved. And no errors thrown.
Any help with this would be greatly appreciated.
I did get this to work, (in case anyone is having the same issue and stumbles upon this), by creating the node first and then adding the location data to the node with:
$locations = array();
$locations[0]['postal_code'] = $zip;
$criteria = array();
$criteria['nid'] = $node->nid;
$criteria['vid'] = $node->vid;
$criteria['genid'] = 'NAME OF NODE TYPE HERE';
location_save_locations( $locations, $criteria );
I guess location_save_locations is the correct way of doing it, not location_save.
Following your approach, as exposed by the wider location_save_locations() at line 4, you can update a location with location_save($locations[$key], TRUE, $criteria).
A few notes:
location_save return the lid of the saved location, or FALSE if the location is considered "empty."
Clean your cache or query the database ( mysql> SELECT * FROM location ORDER BY lid DESC limit 6 ) for a fresh view of the new entity location (ie: node_load data may be cached).
Alternatively, if you are handling an entity with a location field, you may try something cleaner like:
// Updated the location.
$node->field_location['und'][0] = $location;
// Save the node.
node_save ($node);
