I created a WordPress post form that works well

And I want to add a field:

Browser recording audio file Based on base64 - (blob file)

And upload when posting. My javascript code is : https://subinsb.com/html5-record-mic-voice/

This is my code example:

 <?php
      if ( isset( $_POST['submitted'] ) && isset( $_POST['post_nonce_field'] ) && wp_verify_nonce( $_POST['post_nonce_field'], 'post_nonce' ) ) {

    if ( trim( $_POST['postTitle'] ) === '' ) {
        $postTitleError = 'Please enter a title.';
        $hasError = true;
    }

    $post_information = array(
        'post_title' => wp_strip_all_tags( $_POST['postTitle'] ),
        'post_content' => $_POST['postContent'],
        'episode' => $_POST['postEpisode'],
        'post_type' => 'post',
        'post_status' => 'draft'
    );

    $post_id = wp_insert_post( $post_information );
    add_post_meta($post_id, 'episode', $_POST['postEpisode'], true);



    /* upload file here */

    $file_name = $_FILES['fileToUpload']['name'];
    $file_temp = $_FILES['fileToUpload']['tmp_name'];

    $upload_dir = wp_upload_dir();
    $image_data = file_get_contents( $file_temp );
    $filename = basename( $file_name );
    $filetype = wp_check_filetype($file_name);
    $filename = time().'.'.$filetype['ext'];

    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 );
    require_once( ABSPATH . 'wp-admin/includes/image.php' );
    $attach_data = wp_generate_attachment_metadata( $attach_id, $file,$post_id );
    wp_update_attachment_metadata( $attach_id, $attach_data,$post_id );

    echo $attach_id;
    }





?>
<?php if ( $postTitleError != '' ) { ?>
    <span class="error"><?php echo $postTitleError; ?></span>
    <div class="clearfix"></div>
    <?php } ?>
    <?php
    if ( $post_id ) {
    wp_redirect( home_url() );
    exit;
    }
    ?>
   <form action="" id="primaryPostForm" method="POST" enctype="multipart/form-data">

    <fieldset>
        <label for="postTitle"><?php _e('Post Title:', 'framework') ?></label>

        <input type="text" name="postTitle" id="postTitle" class="required" value="" />
    </fieldset>

    <fieldset>
        <label for="postContent"><?php _e('Post Content:', 'framework') ?></label>

        <textarea name="postContent" id="postContent" rows="8" cols="30" class="required"></textarea>

        <label for="postEpisode"></label>

        <textarea name="postEpisode" id="postEpisode" rows="8" cols="30" class="required"></textarea>

    <?php

    ?>
    <audio controls id="audio"></audio>

        </div>



    <canvas id="level" height="200" width="500"></canvas>


    <fieldset>
    <?php wp_nonce_field( 'post_nonce', 'post_nonce_field' ); ?>
        <input type="hidden" name="submitted" id="submitted" value="true" />

        <button type="submit"><?php _e('Add Post', 'framework') ?></button>
    </fieldset>

     </form>

I have searched several websites and unfortunately found no right solution to this problem.

I want to upload this file along with the post.And display in a custom field in the backend

Can anyone help me?

  • What happens - what specifically isn't working? And why do you want the user to base64 encode their audio files before uploading? You're saving it as an attachment so binary is fine. When you say your form works fine, does the client-side insert post work fine, it's just the attachment you're having problems with? – Rup Dec 24 '19 at 9:40
  • @Rup Thanks for your question. Yes. The form is well submitted but does not attach any files The user records his voice using the microphone(ex: in chrome) and sends the form along with other fields. The problem is that the audio file is recorded by the browser as base64. How to post this recorded file with other fields? – yasin taqizade Dec 24 '19 at 13:19
