  Submitting WordPress post from frontend without a plugin 

  

  Screen Shot

  About

  This tutorial will guide you to create your own custom post composing form to enable fast blogging with your favorite theme without adding a plugin. I’m looking for any alternative to not porting P2, however…. none.,  finally that’s the reason i wrote it, and It was also inspired by the original development from http://wpshout.com/wordpress-submit-posts-from-frontend/.

  Why

  I found the code from http://wpshout.com/wordpress-submit-posts-from-frontend/ , but it doesn’t  handle file attachment, indeed most people and I was demand on image uploads for status update,  photo blogging.. whatever . But to get working with build-in WordPress media upload function require a lots of code work,  and if you prefer a fully functional media library, you could base on P2 theme instead.

  How it work

  1. It create a post form to allow  the post content inserted by wp_insert_post.
  2. following the post_id, it attach the uploaded files to the post.
  3. Set the first ordered image to the post “featured images”
  4. Lastly, you call get_all_thumbnails before the_content() in order to retrieve the uploaded files.

  Limitation

  The critical limitation is lack of media features, unlike build-in media library, you can customize your post images and place it on your desired position. Therefore the images only able to retrieve by the_post_thumbnail() for single image or get_all_thumbnails() for multiple images.

  WordPress post navigation with customized post loop using meta_key 

  What’s that?

  I wrote this stupid navigation workout because I can’t found any of good practice on writing customized content unless I go for WordPress 3.0. When I create several content handling in a themes, such as photo post or video post, I was relied on the meta_key value to determine which style to be used.

  For each single post or post loop, it’s no problem at all, however when i tried to do navigation on the single.php. I noticed that there is no way to treat them as typical blog post.

  <?php
          $category = get_the_category();
          $catID = $category[0]->cat_ID;
  ?>
  
      <?php if (have_posts()) : while (have_posts()) : the_post(); ?>
  <?php the_content();?>
          <?php endwhile; else: ?>
  <p>Sorry, no posts matched your criteria.</p>
          <?php endif; ?>
  
  <!-- Start navigation here -->
  <?php
  global $post;
  $mypostlist = array();
  $currentPID = $post->ID;
  $myNav[] += $currentPID;  //insert the current post into first array position
  $myposts = get_posts('exclude='.$post->ID.'&orderby=date&order=desc&numberposts=-1&meta_key=my_post_type&meta_value=1&offset=1&category='. $catID .'');
  setup_postdata($post); // exclude current post from the loop
  foreach ($myposts as $post) {
         $myNav[] += $post->ID; // insert the result into the loop
  }
  $current = array_search($post->ID, $myNav);
  $prevID = $myNav[$current-1];
  $nextID = $myNav[$current++];
  ?>
  
  <div class="navigation">
  <?php if (!empty($prevID)) { ?>
  <div class="alignleft"><a href="<?php echo get_permalink($prevID); ?>"
    title="<?php echo get_the_title($prevID); ?>">Previous</a>
  </div>
  <?php }
  if (!empty($nextID)) { ?>
  <div class="alignright"><a href="<?php echo get_permalink($nextID); ?>"
   title="<?php echo get_the_title($nextID); ?>">Next</a></div>
  <?php } ?>
  </div><!-- .navigation -->
  
  </div>

  "myvar7" => array("stock" => "I", "mykey" => "2", "name" => "orange"),
  "myvar8" => array("stock" => "J", "mykey" => "2", "name" => "orange"),
  );
  
  $_myvars = array();
  foreach($myvars as $myvar)
  {
  if ( !in_array($myvar['mykey'], $_myvars) )
  {
  echo $myvar['mykey'] . "\n" . $myvar['name'] . "\n";
  $_myvars[] = $myvar['mykey'];
  }
  }
  ?>
  

  The Result

  1 apple 2 orange

    Followed your instructions to setup FastCGI, all worked well accept at the end, when I hit my website, I get:

    #!/bin/bash
    PHP_CGI=/usr/bin/php-cgi
    PHP_FCGI_CHILDREN=16
    PHP_FCGI_MAX_REQUESTS=1000
    export PHP_FCGI_CHILDREN
    export PHP_FCGI_MAX_REQUESTS
    exec $PHP_CGI

  horde/imp display gb2312 character interim solution 

  While too many gb2312 character in horde cannot converted as UTF-8, to give it a quick workaround, I’d just enforce horde to treat gb2312 encoding to gbk which is more compatible for chinese double-byte character.

  Replace the lines in lib/Horde/String.php from

  if (!$output && String::extensionExists(‘mbstring’)) {
  $output = @mb_convert_encoding($input , $to, $from);
  }

  to

  if (!$output && String::extensionExists(‘mbstring’)) {
  if ($from == ‘gb2312′) {
  $from = ‘GBK,GB2312′;
  }
  $output = @mb_convert_encoding($input , $to, $from);
  }
