php - Get div content value during print post data? -


i new wordpress , php , want div content data when print_r($_post)

i used add_action( 'save_post', 'wpse_save_meta_fields' ); wordpress hook save data or update data.

when print_r($_post) things except selected_element_all div content.

how data or resolve ?

jquery code ( data file)

jquery(document).ready(function() {   var postid = "<?php echo $post_id;?>";   jquery("#sel_all_mmy").click(function() {     jquery.ajax({       data: {         'post_id': postid       },       type: 'post',       datatype: 'json',       url: "<?php echo get_template_directory_uri();?>/get_all_make_model.php?",       success: function(data) {         jquery(".selected_element_all").append(data);       }     });   }); });

html div append data

<div  class="selected_element_all" style="font-size:15px">  </div>

and php code used 

<?php       function wpse_save_meta_fields( $post_id ) {         global $wpdb;          echo "<pre>";         print_r($_post);         exit();     }      add_action( 'save_post', 'wpse_save_meta_fields' ); ?>

try way

take input hidden field in div like

<input type=hidden name="my_val" class="my_val" value="">   </div>

then use in jquery script like

jquery(document).ready(function(){     var postid ="<?php echo $post_id;?>";     jquery("#sel_all_mmy").click(function(){         jquery.ajax({         data:{'post_id':postid},         type:'post',         datatype: 'json',         url: "<?php echo get_template_directory_uri();?>/get_all_make_model.php?",         success: function(data){              jquery(".selected_element_all").data(data);              jquery(".my_val").val(data);             }         });     }); });

and print_r value in php function print_r($_post['my_val']);

i hope it's working.
