wp_insert_post with a form

Answer 1

This should work.

<?php 
if(isset($_POST['new_post']) == '1') {
    $post_title = $_POST['post_title'];
    $post_category = $_POST['cat'];
    $post_content = $_POST['post_content'];

    $new_post = array(
          'ID' => '',
          'post_author' => $user->ID, 
          'post_category' => array($post_category),
          'post_content' => $post_content, 
          'post_title' => $post_title,
          'post_status' => 'publish'
        );

    $post_id = wp_insert_post($new_post);

    // This will redirect you to the newly created post
    $post = get_post($post_id);
    wp_redirect($post->guid);
}      
?>      

<form method="post" action=""> 
    <input type="text" name="post_title" size="45" id="input-title"/>
    <?php wp_dropdown_categories('orderby=name&hide_empty=0&exclude=1&hierarchical=1'); ?>
    <textarea rows="5" name="post_content" cols="66" id="text-desc"></textarea> 
    <input type="hidden" name="new_post" value="1"/> 
    <input class="subput round" type="submit" name="submit" value="Post"/>
</form>

If input with name new_post and value of 0 then add the post. No action needed for the form, but you should keep the PHP part on the top of the header.

try this code

  <?php 
if(isset($_POST['submit'])) {


    $post_title = $_POST['post_title'];
    $post_category = $_POST['cat'];
    $post_content = $_POST['post_content'];
    $custom1= $_POST['add_info'];
    $image_name=$_FILE['feture_image']['name']; 

    $image_url=$_FILE['feture_image']['tmp_name'];

    $new_post = array(
          'post_type' => 'news', 
          'post_content' => $post_content, 
          'post_title' => $post_title,
          'post_status' => 'publish'
        );

    $post_id = wp_insert_post($new_post);
    $post = get_post($post_id);



    add_post_meta($post_id, '_add_info_data', $custom1);    
    wp_set_object_terms( $post_id, array($post_category), '< category_slug_name >' ); 



     $upload_dir = wp_upload_dir();
    $image_data = file_get_contents($image_url);
    $filename = basename($image_url);
    if(wp_mkdir_p($upload_dir['path']))     $file = $upload_dir['path'] . '/' . $filename;
    else                                    $file = $upload_dir['basedir'] . '/' . $filename;
    file_put_contents($file, $image_data);

    $wp_filetype = wp_check_filetype($filename, null );
    $attachment = array(
        'post_mime_type' => $wp_filetype['type'],
        'post_title' => sanitize_file_name($filename),
        'post_content' => '',
        'post_status' => 'inherit'
    );
    $attach_id = wp_insert_attachment( $attachment, $file, $post_id );
    require_once(ABSPATH . 'wp-admin/includes/image.php');
    $attach_data = wp_generate_attachment_metadata( $attach_id, $file );
    $res1= wp_update_attachment_metadata( $attach_id, $attach_data );
    $res2= set_post_thumbnail( $post_id, $attach_id );







}      


?>      






<form method="post" enctype="multipart/form-data" > 
    <input type="text" name="post_title" size="45" id="input-title"/>
    <?php wp_dropdown_categories('orderby=name&hide_empty=0&exclude=1&hierarchical=1&taxonomy=< taxonomy name >&post_type=< post_type >'); ?>
    <textarea rows="5" name="post_content" cols="66" id="text-desc"></textarea> 
    <input type="file" name="feture_image">
    <input type="text" name="add_info">
    <input class="subput round" type="submit" name="submit" value="Post"/>   
</form>

Answer 3

leave the form action blank means it will flow form data from entry point of application to the current url in address bar

<form method="post" action="">
