wordpress - Updating post in frontend: send post ID to functions.php -

this simple form i'm suing update posts in frontend:

<?php $current_post = $post->id; ?>  <form action="" method="post">     <input type="text" name="title" value="<?php echo $title; ?>">     <textarea name="text"><?php echo $content; ?></textarea>     <input type="submit" value="edit post">     <?php wp_nonce_field( 'edit_post', 'edit_post_nonce' ); ?>     <input type="hidden" name="edit_post" value="true" /> </form> 

in functions.php, have following script (i remove verifications lines):

if( 'post' == $_server['request_method'] && !empty( $_post['edit_post'] )) {     global $current_post;      $post = array(         'id' => $current_post,         'post_type'     => 'post',         'post_title'    => wp_strip_all_tags($_post['title']),         'post_content'  => wp_strip_all_tags($_post['text']),         'post_status'   => 'publish'     );      $post_id = wp_update_post( $post );      if ( $post_id ) {         wp_redirect( home_url('list-posts/?status=edit') );         exit;     } } 

but instead edit post, wp create new one. because $current_post value not sent functions.php. how can without using input store post id?

update

problem fixed:

function edit_post_foo($query){    $id = get_the_id();     $post = array(         'id' => $id,         'post_type'     => 'post',         'post_title'    => wp_strip_all_tags($_post['title']),         'post_content'  => wp_strip_all_tags($_post['text']),         'post_status'   => 'publish'     );      $post_id = wp_update_post( $post );      if ( $post_id ) {         wp_redirect( $_server['http_referer'] );         exit;     } }  if( 'post' == $_server['request_method'] && !empty( $_post['edit_post'] )) {      if ( ! isset( $_post['edit_post_nonce'] ) ) {         return;     }      if ( ! wp_verify_nonce( $_post['edit_post_nonce'], 'edit_post' ) ) {         return;     }      if ( isset( $_post['post_type'] ) && 'post' == $_post['post_type'] ) {          if ( ! current_user_can( 'edit_posts' ) ) {             return;         }     }      if(empty(trim($_post['title']))){         $erro = "inform title.";         return;     }      if(empty(trim($_post['text']))){         $erro = "sen text.";         return;     }      add_action("wp", "edit_post_foo"); } 

i maybe find solution.

first, in form add input type name="action" , value="your_custom_function"

then

create function in functions.php

function your_function($query) {    $id = get_the_id();     //     wp_redirect( $_server['http_referer'] );    exit; } if( isset($_post["action"]) && $_post["action"] == "your_custom_value" )   add_action("wp", "your_function"); 

at moment, can current id of current post. update post. id stay hidden user.

it's work if send form on page of post.
