The WordPress way to access PHP variables with JavaScript is to use wp_localize_script(). function wpse_enqueue_scripts(){ wp_enqueue_script( ‘wpse’, PATH_TO . ‘script.js’ ); wp_localize_script( ‘wpse’, ‘credentials’, $credentials ); } add_action( ‘wp_enqueue_scripts’, ‘wpse_enqueue_scripts’ ); Then in your JavaScript, you can access the credentials like console.log( credentials );
Start from a working code base.. add_action(‘in_admin_header’, ‘my_ajax_button’); function my_ajax_button() { echo ‘<a href=”#ajaxthing” class=”myajax”>Test</a>’; } add_action(‘admin_head’, ‘my_action_javascript’); function my_action_javascript() { ?> <script type=”text/javascript” > jQuery(document).ready(function($) { $(‘.myajax’).click(function(){ var data = { action: ‘my_action’, whatever: 1234 }; // since 2.8 ajaxurl is always defined in the admin header and points to admin-ajax.php $.post(ajaxurl, data, function(response) … Read more
In WordPress, nonces are specific to the user, the action being performed, and the time. With regards to time, a nonce is valid for 24 hours, and changes every 12 hours. This is considered an acceptable trade-off, since using a real number-used-once would involve adding a tracking system and having storage of the used nonces. … Read more
There is a very important programming principle: DRY – Don’t repeat yourself. Whenever you realize you are repeating almost the same job try to write an abstraction. For your pad* shortcodes this means: function get_padding( $atts ) { $args = shortcode_atts( array( ‘num’ => 10 ), $atts ); return str_repeat( ‘ ‘, (int) $args[‘num’] ); … Read more
Yes, there is: https://make.wordpress.org/core/2012/11/30/new-color-picker-in-wp-3-5/ 1. You should enqueue scripts and styles… add_action( ‘admin_enqueue_scripts’, ‘mw_enqueue_color_picker’ ); function mw_enqueue_color_picker( $hook_suffix ) { // first check that $hook_suffix is appropriate for your admin page wp_enqueue_style( ‘wp-color-picker’ ); wp_enqueue_script( ‘my-script-handle’, plugins_url(‘my-script.js’, __FILE__ ), array( ‘wp-color-picker’ ), false, true ); } 2. … add an input… <input type=”text” value=”#bada55″ class=”my-color-field” … Read more
We can use the show_avatars option to remove the Profile Picture section. We can visit /wp-admin/options.php to turn it off manually. Or update it with: update_option( ‘show_avatars’, 0 ); Or modify it through a filter: add_filter( ‘option_show_avatars’, ‘__return_false’ ); We could also restrict it to the profile.php page: add_action( ‘load-profile.php’, function() { add_filter( ‘option_show_avatars’, ‘__return_false’ … Read more
There is no other way, but I can not see how you need any other way then this. I believe that the insert ID accessed by $wpdb is the last ID by this instance of WPDB, other inserts should not affect that but I’m not sure. <?php $wpdb->insert(“QUERY”); $this_insert = $wpdb->insert_id; ?>
You’re missing the point that there is collation not only for the DB but as well for tables and even fields. Therefore from your point of view, I assume that your CREATE TABLE statement is “not complete”. Before using SQL statements, please learn the language first. See CREATE TABLE Syntax (MySQL Manual). Especially table_options / … Read more
You can simply put your init code within the constructor of the class. For example: class myWidget extends WP_Widget{ function myWidget(){ // Init code here } function widget( $args, $instance ) { // The widget code wp_enqueue_script(…); wp_enqueue_style(…); } // Over methods… } register_widget(‘myWidget’); My preference is to actually put the enqueue calls within the … Read more
Use a file to write the events to. There are several drawbacks here; Filesystem permissions. When you deploy your app, you will have to take care to remember to give the webserver permission to write to the file. And to be extra sure, you’d have to write code which checks whether you can write to … Read more
