In this tutorial I’m going to show you a quick trick to make a custom post option like a QuickPress in your WordPress dashboard. This will allow you to create your own options with custom field for a quick and easy blogging. So, let’s get started…

---

First of all we have to create out custom option panel in dashboard to get started, here is the code…

// Dashborad Posting Page - Gajaparan.com
function dashboard_post_function() {
    echo ‘Hellow World!!’;
} 

// Create the function use in the action hook
function dashboard_post_widget() {
    wp_add_dashboard_widget('dashboard_post_widget', 'MyPress', 'dashboard_post_function');
}

// Hoook into the 'wp_dashboard_setup' action to register our other functions
add_action('wp_dashboard_setup', 'dashboard_post_widget' );

Result

 

Now, let’s add the html form inside the option panel.

    echo '<div id="wrap">
<form action="" method="post">
<table border="1" width="700">
  <tr>
    <td><label for="post_title">Title</label></td>
    <td><input name="post_title" type="text" size="60" /></td>
  </tr>
  <tr>
    <td><label for="content">Content</label></td>
    <td><textarea cols="70" rows="3" class="mceEditor" name="content"></textarea></td>
  </tr>
  <tr>
    <td><label for="post_image">Post Image</label></td>
    <td><input name="post_image" type="text" size="60" value="image url" /></td>
  </tr>
   <tr>
    <td><label for="tag">TAG</label></td>
    <td><input name="tag" type="text" size="60"/></td>
  </tr>
</table>
  <p>Woow… I did it…!!</p>
  <br/>
<input name="submit" type="submit" value="Publish" class="button-primary" />
</form>
</div>';

Result

Now add the following code to make it work…

$postTitle = $_POST['post_title'];
$cont = $_POST['content'];
$tags = $_POST['tag'];
$submit = $_POST['submit'];

add_action('publish_post', 'add_custom_field_automatically');

function add_custom_field_automatically($post_ID) {
	global $wpdb;
	$image = $_POST['post_image'];
	add_post_meta($post_ID, 'pimage', $image, true);

}

if( isset($submit) && !empty( $_POST['post_title'] )) {
    global $user_ID;
  // Get current User Information
  require_once (ABSPATH . WPINC . '/pluggable.php');
  global $current_user;
  get_currentuserinfo();

    $new_post = array(
        'post_title' => $postTitle,
        'post_content' => $cont,
	'tags_input' => $tags,
	'get_post_meta' => $image,
        'post_status' => 'publish',
        'post_date' => date('Y-m-d H:i:s'),
         'post_author' => $current_user->ID,
        'post_type' => 'post',
    );

    wp_insert_post($new_post);
}

So finally our code looks like this:

// Dashborad Posting Page - Gajaparan.com
function dashboard_post_function() {
    echo '<div id="wrap">
<form action="" method="post">
<table border="1" width="700">
  <tr>
    <td><label for="post_title">Title</label></td>
    <td><input name="post_title" type="text" size="60" /></td>
  </tr>
  <tr>
    <td><label for="content">Content</label></td>
    <td><textarea cols="70" rows="3" class="mceEditor" name="content"></textarea></td>
  </tr>
  <tr>
    <td><label for="post_image">Post Image</label></td>
    <td><input name="post_image" type="text" size="60" value="image url" /></td>
  </tr>
   <tr>
    <td><label for="tag">TAG</label></td>
    <td><input name="tag" type="text" size="60"/></td>
  </tr>
</table>
  <p>Woow… I did it…!!</p>
  <br/>
<input name="submit" type="submit" value="Publish" class="button-primary" />
</form>
</div>';
} 

// Create the function use in the action hook
function dashboard_post_widget() {
    wp_add_dashboard_widget('dashboard_post_widget', 'MyPress', 'dashboard_post_function');
}

// Hoook into the 'wp_dashboard_setup' action to register our other functions
add_action('wp_dashboard_setup', 'dashboard_post_widget' );

// $_POST['****']; - * value should be your name="***" of you input form or textarea.
$postTitle = $_POST['post_title']; // title
$cont = $_POST['content'];	// content
$tags = $_POST['tag'];	// tags
$submit = $_POST['submit'];	// submit button...

//add custom field automatically to your post
add_action('publish_post', 'add_custom_field_automatically');

function add_custom_field_automatically($post_ID) {
	global $wpdb;
	//store the image url in $image variable.
	$image = $_POST['post_image'];

	// add it to custom field "pimage"....
	add_post_meta($post_ID, 'pimage', $image, true);

}

// if title not empty - submit button works...
if( isset($submit) && !empty( $_POST['post_title'] )) {
    global $user_ID;

  // Get current User Information
  require_once (ABSPATH . WPINC . '/pluggable.php');
  global $current_user;
  get_currentuserinfo();

    $new_post = array(
	// add the title for the post
        'post_title' => $postTitle,
	// the content
        'post_content' => $cont,
	// add the tags
		'tags_input' => $tags,
	// add the custom field...
		'get_post_meta' => $image,
	// finally your done....
        'post_status' => 'publish',
        'post_date' => date('Y-m-d H:i:s'),
       	// Show the author
        'post_author' => $current_user->ID,
        'post_type' => 'post',
    );

    wp_insert_post($new_post);
}
