Wordpress favorite system without plugin learning method

Good afternoon devs, I developed a favorite system using Wordpress and php, it works as follows, clicking on the add favorites icon I send an ajax request to php with the favorite id and the user id logged in. php processes this by saving in user_meta the information with number of favorite users and in the logged user an array with the ids of the favorites. Anyway, the question is, the system is working, but whenever I develop something I keep wondering if there is a way to improve the code, if there is a way to do it in a better way, I will leave my code here.
All this for learning ok?
HTML
<div class="stats -favorites">
<a class="icon -click <?php echo is_favorite(get_current_user_id(), $user_ID) ? 'fa' : 'far' ?> fa-heart" data-js="favorite" data-favorite="<?php echo $user_ID; ?>" data-user="<?php echo get_current_user_id(); ?>"></a>
<span class="label" data-js="favorite_label">
<?php echo get_favorites_num( $user_ID ); ?>
</span>
<span class="value">favoritos</span>
</div>
JS
function setFavorite(userid, favoriteid) {
var favorite_field = $('[data-js="favorite"]');
var favorite_label = $('[data-js="favorite_label"]');
$.ajax({
url : appmeninas_ajax_params.ajaxurl,
data : {
'action' : 'setfavorite',
'userid' : userid,
'favoriteid' : favoriteid,
},
dataType : 'json',
type : 'POST',
cache : false,
beforeSend : function( xhr ) {
favorite_field.removeClass('far fa fa-heart').addClass('fas fa-circle-notch fa-spin');
},
success : function( data ) {
var icon = (data.is_favorite) ? 'fa fa-heart' : 'far fa-heart';
favorite_field.removeClass('fas fa-circle-notch fa-spin');
favorite_field.addClass(icon);
favorite_label.html('');
favorite_label.append(data.favorites_num);
}
});
};
$('[data-js=favorite]').click(function() {
var favoriteid = $(this).data('favorite');
var userid = $(this).data('user');
setFavorite(userid, favoriteid);
});
PHP
function setfavorite() {
$userid = $_POST['userid'];
$favoriteid = $_POST['favoriteid'];
// user require favorite
$favorites_list = get_field( 'favorites_list', 'user_' .$userid );
$favorites_num = get_field( 'favorites', 'user_' .$favoriteid );
if ( !$favorites_list ) {
$favorites_list = [];
}
// profile favorite
if ( in_array( $favoriteid, $favorites_list ) ) {
$favorites_num--;
$tmp = array_search( $userid, $favorites_list );
array_splice( $favorites_list, $tmp, 1 );
$is_favorite = false;
} else {
$favorites_num++;
$favorites_list[] = $favoriteid;
$is_favorite = true;
}
// set favorite counter
update_user_meta( $favoriteid, 'favorites', $favorites_num );
// set favorite list
update_user_meta( $userid, 'favorites_list', $favorites_list );
echo json_encode( array(
'favorites_num' => $favorites_num,
'favorites_list' => $favorites_list,
'is_favorite' => $is_favorite,
) );
die();
}
function is_favorite($userid, $favoriteid) {
$favorites_list = get_field( 'favorites_list', 'user_' .$userid );
return in_array( $favoriteid, $favorites_list );
}
function get_favorites_num( $userid ) {
if ( get_field( 'favorites', 'user_' .$userid ) ) {
return get_field( 'favorites', 'user_' .$userid );
} else {
return '0';
}
}
add_action('wp_ajax_setfavorite', 'setfavorite');
add_action('wp_ajax_nopriv_setfavorite', 'setfavorite');

i maybe will implement a same function in the next 2 months. i allready started researching plugins but as your question states, it does not seems to be very hard.
I try to come back then but first i need a frontend profile page where i can list the favorites.
The first impression looks good so far but first i would give attention to the $_POST array and sanitize and maybe validate the values because sometimes not only your ajax will call.
if ( isset($_POST['userid']) && isset($_POST['favoriteid']) ) { // Both $_POST values exist
$userid = filter_var($_POST['userid'], FILTER_SANITIZE_NUMBER_INT);
$favoriteid = filter_var($_POST['favoriteid'], FILTER_SANITIZE_NUMBER_INT);
if ( filter_var($userid, FILTER_VALIDATE_INT) && filter_var($favoriteid, FILTER_VALIDATE_INT) ) {
// $_POST was save, both values are Integers
}
}
The second one is related to get_field which is a function provided by the ACF Plugin. therefor when deactivating it or it gets replaced with JCF, it may cause errors.
You can avoid this by using if ( function_exists('get_field') ) {. Then your code only stops working when ACF gets deactivated.
Otherwise it seems not neccessary to use the ACF function and you can use the WP native function get_user_meta instead:
function is_favorite($userid, $favoriteid){
$favorites_list = get_user_meta($userid, 'favorites_list', true);
// check the new output instead of get_field
return in_array( $favoriteid, $favorites_list );
}
and also all calls to get_field('favorites', 'user_' .$favoriteid) seem to be wrong then. The ACF Docs say the the second parameter of get_field ist a post ID so i don't know what 'user_' means then. I would call:
function get_favorites_num($favoriteid){
return get_user_meta($favoriteid, 'favorites', true) || 0;
}
i now have my own favorite system ready where users can favorite posts from a specific post_type
HTML
<?php while ( have_posts() ) : the_post() ?>
<?php
$customPostsMeta = get_post_custom();
$favorite_class = 'favorite-me disabled';
$fav_count = isset($customPostsMeta['_favorites']) ? intval($customPostsMeta['_favorites'][0]) : 0;
$fav_count_text = $fav_count > 0 ? '(' . $fav_count . ')' : '';
$fav_count = ' <span class="fav-count clearfix">' . $fav_count_text . '</span>';
$favorite_title = '';
if ( is_user_logged_in() ) {
$user = wp_get_current_user();
$favorites = get_user_meta($user->ID, '_favorite_posts', true);
$fav_key = array_search($post_id, $favorites);
$is_favorite = ( $fav_key !== false );
if ( $is_favorite ) {
$favorite_class .= ' is-favorite';
$favorite_title = ' title="' . get_the_title() . ' ' . __('favorisieren', 'myTheme') . '"';
} else {
$favorite_title = ' title="' . get_the_title() . ' ' . __('nicht mehr favorisieren', 'myTheme') . '"';
}
}
?>
<a class="<?php echo $favorite_class; ?>" href="#post-<?php the_ID() ?>"<?php echo $favorite_title; ?>><?php echo __('Favorit', 'myTheme')?><?php echo $fav_count; ?></a>
<?php endwhile; ?>
JS
// i use a small self written JS module frame where this is included as module
// favorite.setup() is fired imediatly, favorite.ready() fires on document ready

}
this are the things i noticed on the way:
verify referer with wp_create_nonce() and check_ajax_referer()
check JSON result data keys for existance with data.hasOwnProperty('key') to avoid possible JS errors
check valid WP_User or WP_Post object
current users ID with is not necessary to send with POST
wp_ajax_nopriv_{action} is not necessary when feature is only for logged in users
use wp_send_json() for ending the response

Send php value with jQuery ajax function to php function

I have an ajax form that filters posts based on the category.
Setup:
HTML form
PHP function to echo ouput
jQuery ajax request to load php
function
Question: How can I parse a value to the php function ($test, see below) from within the jQuery ajax function?
Form - Outputs html select field and button to filter posts
<form action="<?php echo site_url() ?>/wp-admin/admin-ajax.php" method="POST" id="filter">
<?php
if( $terms = get_terms( 'category', 'orderby=name' ) ) : // to make it simple I use default categories
echo '<select name="categoryfilter"><option>Select category...</option>';
foreach ( $terms as $term ) :
echo '<option value="' . $term->term_id . '">' . $term->name . '</option>'; // ID of the category as the value of an option
endforeach;
echo '</select>';
endif;
?>
<button>Apply filter</button>
<input type="hidden" name="action" value="myfilter">
</form>
<div id="response"></div>
PHP function - Outputs result on button click in HTML form
function misha_filter_function($test){
// Do something with $test, but how to parse it with jQuery into this php function?
$args = array(
'orderby' => 'date', // we will sort posts by date
'order' => $_POST['date'] // ASC или DESC
);
// for taxonomies / categories
if( isset( $_POST['categoryfilter'] ) )
$args['tax_query'] = array(
array(
'taxonomy' => 'category',
'field' => 'id',
'terms' => $_POST['categoryfilter']
)
);
$query = new WP_Query( $args );
if( $query->have_posts() ) :
while( $query->have_posts() ): $query->the_post();
echo '<h2>' . $query->post->post_title . '</h2>';
endwhile;
wp_reset_postdata();
else :
echo 'No posts found';
endif;
die();
}
add_action('wp_ajax_myfilter', 'misha_filter_function');
add_action('wp_ajax_nopriv_myfilter', 'misha_filter_function');
jQuery - Question: how to parse php value $test to the above php function?
jQuery(function($){
$('#filter').submit(function(){
var filter = $('#filter');
$.ajax({
url:filter.attr('action'),
data:filter.serialize(), // form data
type:filter.attr('method'), // POST
beforeSend:function(xhr){
filter.find('button').text('Processing...'); // changing the button label
},
success:function(data){
filter.find('button').text('Apply filter'); // changing the button label back
$('#response').html(data); // insert data
}
});
return false;
});
});

You serialize data so accesed by:
parse_str($_POST['data'], $inputValues); //$inputValues will be array with your form fields

How to implement a live search for multiple text fields inside one column of a table?

I have currently implemented a live search (search as you type) function on text fields. The flow is something like this.
Call a .js file inside the page.
Set the id of the text field to "client-search".
Inside the .js file it is currently listening for on key up events of the "client-search" text field.
If the on key up event is fired, the .js file calls a PHP file that searches the database and returns the output as a list item in an unordered list underneath the "client-search" text field.
This setup currently works but how do implement it in multiple fields inside a single page, since it works using "id" and obviously I can't have multiple IDs in a single page.
HTML:
<div class="input-group">
<input type="text" id="client-search" class="form-control" placeholder="Search for manager...">
<ul class="livesearch" id="client-result" onclick="clickResult()"></ul>
</div>
JS
/* JS File */
// Start Ready
$j(document).ready(function() {
// Icon Click Focus
$j('div.icon').click(function(){
$j('input#client-search').focus();
});
// Live Search
// On Search Submit and Get Results
function search() {
var query_value = $('input#client-search').val();
$j('b#search-string').text(query_value);
if(query_value !== ''){
$j.ajax({
type: "POST",
url: "clientsearch.php",
data: { query: query_value },
cache: false,
success: function(html){
$("ul#client-result").html(html);
}
});
}return false;
}
$j("input#client-search").live("keyup", function(e) {
// Set Timeout
clearTimeout($.data(this, 'timer'));
// Set Search String
var search_string = $(this).val();
// Do Search
if (search_string == '') {
$j("ul#client-result").fadeOut();
}else{
$j("ul#client-result").fadeIn();
$j(this).data('timer', setTimeout(search, 100));
};
});
});
PHP:
<?php
$serverName = "(local)";
$connectionInfo = array( "Database"=>"CMS");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn ) {
} else {
echo "Connection could not be established.<br />";
die( print_r( sqlsrv_errors(), true));
}
$html = '';
$html .= '<li value="myLi" class="myLi">';
$html .= '<small>nameString</small>';
$html .= '<small></small>';
$html .= '</li>';
$search_string = $_POST['query'];
//$search_string = preg_replace("/[^A-Za-z0-9]/", " ", $_POST['query']);
if (strlen($search_string) >= 1 && $search_string !== ' ') {
$sql = "SELECT TOP 10 ClientName FROM Client WHERE ClientName LIKE '%" . $search_string . "%'";
$params = array($search_string);
$stmt = sqlsrv_query( $conn, $sql);
while( $row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_ASSOC) ) {
$results_array[] = $row;
}
if (isset($results_array)) {
foreach ($results_array as $result) {
$display_function = $result['ClientName'];
$display_name = $result['ClientName'];
$output = str_replace('nameString', $display_name, $html);
//$output = str_replace('functionString', $display_function, $output);
echo($output);

$output = str_replace('nameString', '<b>No Results Found.</b>', $html);
$output = str_replace('functionString', 'Sorry :(', $output);
echo($output);
}
}

Display Output During Each Iteration of for Loop

I want to show a message displaying the result of each iteration of a for loop in php.
I have tried several methods using jquery, ajax etc but they doesn't seem to fit my needs or either i am not getting to work around with them.
What my script does?
It scans a website, grab some links, then visits each link one by one and grab an image from each page and finally send it to my wordpress including its title and image.
What's the problem?
The problem is that as there can be several links (more than 200), so even though my scripts displays message regarding the success but it shows the messages after the whole loop is finished executing.
What I want to do?
Now, what i want to do that during each iteration the message should be shown on the browser rather than waiting for the loop to complete i.e. during 1st iteration (Posted Successfully) then during 2nd (Not Posted) and so on...
Here is the code:
<?php
$category = array();
for ($i = 0; $i < count($result); $i++)
{
set_time_limit(30);
// Check if post already exists
global $wpdb;
$query = $wpdb->prepare('SELECT ID FROM ' . $wpdb->posts .
' WHERE post_name = %s',sanitize_title_with_dashes($result[$i]->title));
$cID = $wpdb->get_var($query);
if (!empty($cID))
{
echo $result[$i]->title .
" <font style='color:#FF0000; font-weight:bold;'>Already Exists.</font><br />";
} else
{
$inner_html = file_get_html($result[$i]->href);
$inner_result_image = $inner_html->find('meta[property=og:image]',1);
$inner_result_cats = $inner_html->find('a[rel=category tag]');
$title = $result[$i]->title;
$body = "<a href='$inner_result_image->content'><img src='$inner_result_image->content' /></a>";
// Automatically Create new Category if it doesn't exist.
foreach ($inner_result_cats as $cats)
{
if (!($cats->innertext == "Jobs"))
{
array_push($category,$cats->innertext);
$count = 0;
// For Cities
if (search_city($cats->innertext))
{
wp_insert_term($cats->innertext,'category',array(

Apply Chosen Select Plugin in Wordpress AJAX

P.S. This question is long as there's lot of code. Thank you for your patience and time. I appreciate it.
I am using ultimate wp query search filter plugin on my wordpress site. I would like to use chosen plugin instead of default select boxes. The select boxes already on the page are working perfectly with this code.
(function($){
$(".first-ddwn, .second-ddwn, .third-ddwn, .main-ddwn, .posts_ajax select").chosen({
no_results_text: "Oops, nothing found!",
width: "50%"
});
})(jQuery);
I have changed the result html for AJAX search as mentioned by the plugin author so that I get a dropdown of result posts.
add_filter('uwpqsf_result_tempt', 'customize_output', '', 4);
function customize_output($results , $arg, $id, $getdata ){
// The Query
global $post;
$apiclass = new uwpqsfprocess();
$query = new WP_Query( $arg );
ob_start(); $result = '';?>
<form action="<? bloginfo('url'); ?>" method="get"><?php
echo '<select name="page_id" id="page_id">';
echo '<option value="">Select</option>';
// The Loop
if ( $query->have_posts() ) {
while ( $query->have_posts() ) {
$query->the_post(); ?>
<option value="<? echo $post->ID; ?>"><?php echo the_title(); ?></option>
<?php }
echo '</select>';
echo '<input type="submit" name="submit" value="view" />';
echo '</form>';
} else {
echo 'no post found';
}
/* Restore original Post Data */
wp_reset_postdata();
$results = ob_get_clean();
return $results;
}
However, chosen doesn't get applied to this result dropdown. I have tried the option of using settimeout after the AJAX call as mentioned http://davidwalsh.name/jquery-chosen#comment-29299 but it didn't work. maybe I did it wrong. Also when I run it after ajax call like below, chosen does get applied to the select but is all broken.
jQuery.ajax({
type: 'POST',
url: ajax.url,
timeout:3000,
data: ({action : 'uwpqsf_ajax',getdata:getdata, pagenum:pagenum }),
beforeSend:function() {$(''+ajxdiv+'').empty();res.container.append(res.loader);},
success: function(html) {
res.container.find(res.loader).remove();
$(''+ajxdiv+'').html(html);
$(".content select").chosen();
}
});
This is what I get
This is plugin's uwpqsfscript.js file
