Ajax sends data but php doesn’t recieve it

1. To make it work, you need one more essential thing:

   add_action('wp_enqueue_scripts', 'my_custom_scripts'); 
   my_custom_scripts(){
       // Here you register your script for example located in a subfolder `js` of your active theme
       wp_enqueue_script( 'ajax-script', get_template_directory_uri().'/js/script.js', array('jquery'), '1.0', true );
       // Here you are going to make the bridge between php and js
       wp_localize_script( 'ajax-script', 'my_ajax', array( 'ajaxurl' =>   admin_url( 'admin-ajax.php' ) ) );
   }
   

   See that 'ajax-script' is in both functions wp_enqueue_script() and wp_localize_script()…

   Then you will retrieve 'ajaxurl' and 'my_ajax' in your js combined in url:my_ajax.ajaxurl,:

   jQuery(document).ready(function($) {
   
       jQuery('#bootstrapModalFullCalendar').fullCalendar({
           dayClick:  function(date, event, jsEvent, view) {
                   var date = date.format();
               jQuery.ajax({
                   type: "POST",
                   url: my_ajax.ajaxurl,// Here 'my_ajax' & 'ajaxurl' from wp_localize_script()
                   data: {
                       'action': 'show_scheduled_tweets',
                       'tweetdate': date
                   },
                   beforeSend: function() {
                       console.log('before')
                   },
                   success: function(){
                       console.log('success')
                   },
                   error: function(){
                       console.log('error')
                   },
               });
           }
       });
   });
   

   Now you can get the $_POST["tweetdate"];in your php!!!

   Update: May be you need to add to your php function (for front end):

   add_action('wp_ajax_nopriv_show_scheduled_tweets', 'show_scheduled_tweets');
   

   And to and die();at the end inside your function. so you will have:

   add_action('wp_ajax_show_scheduled_tweets', 'show_scheduled_tweets'); // backend
   add_action('wp_ajax_nopriv_show_scheduled_tweets', 'show_scheduled_tweets'); // fronted
   function show_scheduled_tweets () {
       global $wpdb;
       $tweetdate = $_POST["tweetdate"];
       $query = "SELECT * FROM wp_tweettweet WHERE tweetdate='$tweetdate'";
       $results = $wpdb->get_results($query, ARRAY_A);
   
       foreach($results as $result) {
           $tweet2 =  $result[text];
           $recycleOption = $result[recycle];
           $id = $result[id];
   
           $currentDateTime = $result[time];
           $time = date('h:i A', strtotime($currentDateTime));
   
   
       ?>
   
           <form class="tweetclass form-inline" action="" method="post">
               <input type="checkbox" name="recycle" <?php if($recycleOption == 1){ echo "checked";} ?>>Recycle Tweet?
               <input class="tweetinput" type="text" name="tweetupdate" value="<?php echo $tweet2; ?>">
               <input type="hidden" name="id" value="<?php echo $id; ?>">
               <input type="text" name="timepicker" class="timepicker" value="<?php echo $time; ?>"/>
               <input class="tweetsubmit" type="submit" value="Save">
               <input class="tweetdelete" type="submit" value="delete">
           </form>
       <?php
       }
       die(); // very important to get it working
   }

   Update 2: important! — It should work this time!

   • I have made a little typing error:
     It’s add_action('wp_ajax_nopriv_ … instead of add_action('wp_ajax_no_priv_ …

   • These php codes needs to be on the function.php file of your active theme (or child theme).

   Then you will call your function somewhere else or you can hook it with some add_action() hooks.

   show_scheduled_tweets();
