WordPress add field - wordpress

I would like to add a select field in admin/post-new.php.
This select field will be populated with JSON data (from a GET URL).
^ This point is solved. In your function.php:
function acf_load_colors_field_choices($field) {
$field['choices'] = [];
$choices = json_decode(file_get_contents('http://127.0.0.1/json/colors'), true);
if (is_array($choices)) {
foreach ($choices as $choice) {
$field['choices'][$choice] = $choice;
}
}
return $field;
}
add_filter('acf/load_field/name=colors', 'acf_load_colors_field_choices');
Once the page is ready to be published, I would like to catch POST data to send them to another URL.
How to catch those data?

In functions.php, to catch POST data:
function on_save_post_articles($post_id) {
var_dump($post_id);
var_dump($_POST);
exit;
}
add_action('save_post', 'on_save_post_articles');
Solved!

How to catch the specific page template in WordPress

Here is a screenshot:
I want to catch a specific page template and show meta box according the specific page template. I have tried to with it:
$pageTemplate = get_post_meta($post->ID, '_wp_page_template', true);
but is not working.
Add the following code to functions.php:
add_filter('template_include', 'var_template_include', 1000);
function var_template_include($t) {
$GLOBALS['current_theme_template'] = basename($t);
return $t;
}
function get_current_template() {
if (isset($GLOBALS['current_theme_template'])) {
return $GLOBALS['current_theme_template'];
} else {
return false;
}
}
You'll then be able to do the following:
$pageTemplate = get_current_template();

How to Save Multiple User Metadata in Database?

I am trying to create a registration form (here) with the help of a free plugin.
There are many elements in the registration form.
In the admin panel, meta keys can be assigned for each element in the plugin interface. So there is such an opportunity.
I'm trying to collect many of the elements on the same meta key by taking advantage of this possibility. In this direction, I gave the common meta key value to the elements I created. For example: info_about_register
So far everything is fine. However, if the form is posted, I can only get the last entry in the usermeta table. So the plugin is not serializing the same meta key data. An array does not occur.
There are many form elements. I want to pull these to the admin panel later. Therefore, I think that defining a separate line for each element will tire the system a lot. I contacted the plugin developers about this issue. However, no response for about 1.5 weeks.
I tried to solve this problem myself and found the codes where the action was taken. I made some changes to these. However, I was not successful. I would be very happy if you guide me.

Update:
Data can be stored as an array with a definition like below. Also, the key values ($all_meta_value[$req_key]) are equal to the id, name values automatically assigned to the HTML elements by the plugin.
Using this, different conditional states can be written.
The following code must be defined in the function.php file in the child theme:
add_action('erf_user_meta_updated','for_new_user_meta_uptated',10);
function for_new_user_meta_uptated($data){
//if the defined meta key (info_about_register) matches
if($m_key == 'info_about_register'){
$all_meta_value[$req_key] = $data;
}
}
add_action('erf_user_created', 'for_new_user_created',10);
function for_new_user_created($id){
//Save the values as a new user meta
add_user_meta($id, 'new_info_about_register', $get_meta_value);
//Remove saved single element user meta.
delete_user_meta($id, 'info_about_register');

Session data ends with wrong visitor? How is that possible?

We are facing a problem with a website.
A prospect noticed that a form was prefilled with data from another prospect.
We have 4 contactforms on one page and when a contact has entered a form than the data is saved in a session. When they return the forms are prefilled with that data from the session. But now we got a printscreen from a prospect with data from a previous prospect.
Here's the code for the session:
//This will start a session, then save the posted_data[something] to the session
add_action('init', 'myStartSession', 1);
add_action('wp_logout', 'myEndSession');
add_action('wp_login', 'myEndSession');
function myStartSession() {
if ( empty( $_SESSION ) ) {
session_start();
}
}
function myEndSession() {
session_destroy ();
}
function set_sessions($cf7){
/* Use WPCF7_Submission object's get_posted_data() method to get it. */
$submission = WPCF7_Submission::get_instance();
if ( $submission ) {
$posted_data = $submission->get_posted_data();
}
$_SESSION['formdata']['firstname'] = $posted_data['firstname'];
$_SESSION['formdata']['lastname'] = $posted_data['lastname'];
$_SESSION['formdata']['email2'] = $posted_data['email2'];
$_SESSION['formdata']['tel'] = $posted_data['tel'];
$_SESSION['formdata']['postcode'] = $posted_data['postcode'];
$_SESSION['formdata']['adres'] = $posted_data['adres'];
return false;
}
add_action( 'wpcf7_before_send_mail', 'set_sessions' );
function firstname(){
return $_SESSION['formdata']['firstname'];
}
add_shortcode('firstname', 'firstname');
function lastname(){
return $_SESSION['formdata']['lastname'];
}
add_shortcode('lastname', 'lastname');
function email2(){
return $_SESSION['formdata']['email2'];
}
add_shortcode('email2', 'email2');
function tel(){
return $_SESSION['formdata']['tel'];
}
add_shortcode('tel', 'tel');
function postcode(){
return $_SESSION['formdata']['postcode'];
}
add_shortcode('postcode', 'postcode');
function adres(){
return $_SESSION['formdata']['adres'];
}
add_shortcode('adres', 'adres');
Have you checked if you are caching the pages? This could lead to an issue like that.

How to pre-select a selct box in Ninja Forms from a query string

I am trying to pre select a value within a select field in my contact from on the contact page from another page by passing a query string ?request=call-back. I am using Ninja Forms and the values that I have in my select field are: email-us, call-back
I have tried the following:
add_filter( 'ninja_forms_render_default_value', 'my_ninja_forms_pre_populate', 10, 3 );
function my_ninja_forms_pre_populate( $default_value, $field_type, $field_settings ){
if( 'request' == $field_settings[ 'key' ] ){
$default_value = $_GET['request'];
}
return $default_value;
}
I would like the select field to have call-back already selected.
I didnt need to use the filter that I was attempting. I changed the key value under administration within the ninja form builder and I made sure that none of the values were pre selected.
This drove me mad... but finally I've got a solution:
// register custom get parameter (to use it with get_query_var() for safety reasons)
function add_get_val() {
global $wp;
$wp->add_query_var('request');
}
add_action('init', 'add_get_val');
add_filter('ninja_forms_localize_field_listselect', function ($field) {
if (get_query_var('request')) {
$request = get_query_var('request');
$optionExists = FALSE;
// check if field exists
foreach ($field['settings']['options'] as $option) {
if ($option['value'] === $request) {
$optionExists = TRUE;
break;
}
}
if ($optionExists) {
foreach ($field['settings']['options'] as $key => $option) {
// deselect all fields
$field['settings']['options'][$key]['selected'] = 0;
// select parameter
if ($option['value'] === $request) {
$field['settings']['options'][$key]['selected'] = 1;
}
}
}
}
return $field;
});

Silverstripe 3.2: How to make a custom action button in the CMS to create a new Dataobject and populate it from another one

I'm searching for a way to create a custom action button which allows me to make a new DataObject with pre-filled content from another DataObject. As a simple example: When I have an email and click the "answer"-button in my email-client, I get a new window with pre-filled content from the email before. I need exactly this functionality for my button. This button should appear next to each DataObject in the GridField.
So I know how to make a button and add it to my GridField (--> https://docs.silverstripe.org/en/3.2/developer_guides/forms/how_tos/create_a_gridfield_actionprovider/) and I know how to go to a new DataObject:
Controller::curr()->redirect($gridField->Link('item/new'));
I also found out that there is a duplicate function for DataObjects:
public function duplicate($doWrite = true) {
$className = $this->class;
$clone = new $className( $this->toMap(), false, $this->model );
$clone->ID = 0;
$clone->invokeWithExtensions('onBeforeDuplicate', $this, $doWrite);
if($doWrite) {
$clone->write();
$this->duplicateManyManyRelations($this, $clone);
}
$clone->invokeWithExtensions('onAfterDuplicate', $this, $doWrite);
return $clone;
}
Perhaps it's easier than I think but at the moment I just don't get how to rewrite this to get what I need. Can somebody give me a hint?
That's for sure not the cleanest solution but I think it should do the trick.
At first let's create the custom gridfield action. Here we will save all accessible records in a session and add a query string to the url so that we'll know which object we want to "clone"
public function getColumnContent($gridField, $record, $columnName) {
if(!$record->canEdit()) return;
$field = GridField_FormAction::create(
$gridField,
'clone'.$record->ID,
'Clone',
'clone',
array('RecordID' => $record->ID)
);
$values = Session::get('ClonedData');
$data = $record->data()->toMap();
if($arr = $values) {
$arr[$record->ID] = $data;
} else {
$arr = array(
$record->ID => $data
);
}
Session::set('ClonedData', $arr);
return $field->Field();
}
public function getActions($gridField) {
return array('clone');
}
public function handleAction(GridField $gridField, $actionName, $arguments, $data) {
if($actionName == 'clone') {
$id = $arguments['RecordID'];
Controller::curr()->redirect($gridField->Link("item/new/?cloneID=$id"));
}
}
after adding this new component to our gridfield,
$gridField->getConfig()->addComponent(new GridFieldCustomAction());
we'll need to bring the data into the new form. To do so, add this code directly above "return $fields" on your getCMSFields function so it will be executed every time we'll open this kind of object.
$values = Session::get('ClonedData');
if($values) {
Session::clear('ClonedData');
$json = json_encode($values);
$fields->push(LiteralField::create('ClonedData', "<div id='cloned-data' style='display:none;'>$json</div>"));
}
At the end we need to bring the content back into the fields. We'll do that with a little bit of javascript so at first you need to create a new script.js file and include it in the ss backend (or just use an existing one).
(function($) {
$('#cloned-data').entwine({
onmatch: function() {
var data = JSON.parse($(this).text()),
id = getParameterByName('cloneID');
if(id && data) {
var obj = data[id];
if(obj) {
$.each(obj, function(i, val) {
$('[name=' + i + ']').val(val);
});
}
}
}
});
// http://stackoverflow.com/questions/901115/how-can-i-get-query-string-values-in-javascript#answer-901144
function getParameterByName(name) {
name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
results = regex.exec(location.search);
return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
})(jQuery);
And that's it ... quite tricky. Hope it will solve your problem.
