<?php

    function bguru_register_settings(){

   $default_options=array(
        'bguru_logo'=>'http://templategraphy.com/demo/businessguru/images/logo.png',
        'bguru_vimeo'=>'',
        'bguru_skype'=>'',
        'bguru_dribbble'=>'',

}

    add_action('admin_menu', 'bguru_register_options_page');

    function bguru_options_page(){
        $options=get_option('bguru_options');

        ?>
<div class="wrap">
    <?php
 screen_icon(); ?>
    <h1>Business Guru Options</h1>
    <form method="post" action="options.php"> 
        <?php
 settings_fields('tgbusinessguru'); ?>
            <table class="form-table">
                <tr valign="top">
                    <th><h2>General</h2><th>
                </tr>
                <tr valign="top">

                    <th scope="row"><label for="bguru_logo">Logo:</label></th>

                    <td><input type="text" id="bguru_logo" size="50" name="bguru_options[bguru_logo]" value="<?php echo $options['bguru_logo']; ?>" /></td>

                </tr>

                <tr valign="top">
                    <th><h2>Social Links</h2><th>
                </tr>
                <tr valign="top">
                    <th scope="row"><label for="bguru_vimeo">Vimeo:</label></th>
                    <td><input type="text" id="bguru_vimeo" size="50" name="bguru_options[bguru_vimeo]" value="<?php echo $options['bguru_vimeo']; ?>" /></td>

                 </tr>
                <tr valign="top">
                    <th scope="row"><label for="bguru_skype">Skype:</label></th>
                    <td><input type="text" id="bguru_skype" size="50" name="bguru_options[bguru_skype]" value="<?php echo $options['bguru_skype']; ?>" /></td>
                </tr>
                <tr valign="top">
                    <th scope="row"><label for="bguru_dribbble">Dribbble:</label></th>
                    <td><input type="text" id="bguru_dribbble" size="50" name="bguru_options[bguru_dribbble]" value="<?php echo $options['bguru_dribbble']; ?>" /></td>
                </tr>
                <tr valign="top">

                    <th scope="row"><label for="bguru_slide_one_image">Image:</label></th>

                    <td><input type="text" id="bguru_slide_one_image" size="50" name="bguru_options[bguru_slide_one_image]" value="<?php
 echo $options['bguru_slide_one_image']; ?>" /></td>
                </tr>
                <tr valign="top">
                    <th scope="row"><label for="bguru_slide_one_heading">Heading:</label></th>
                    <td><input type="text" id="bguru_slide_one_heading" size="50" name="bguru_options[bguru_slide_one_heading]" value="<?php
 echo $options['bguru_slide_one_heading']; ?>" /></td>
                </tr>
                <tr valign="top">
                    <th scope="row"><label for="bguru_slide_one_text">Description:</label></th>
                    <td><textarea type="text" id="bguru_slide_one_text" style="width:439px;height:100px;" name="bguru_options[bguru_slide_one_text]"><?php  echo $options['bguru_slide_one_text']; ?></textarea></td>
                </tr>
              </table>
          <?php submit_button(); ?>
       </form>
     </div>
<?php  } ?>

All the form details are passed by dashboard I want if admin forget to fill the logo field then by default this $default_options work so by default logo field fill up but when I try to access the array using get_option I'm not getting the results I expect.

Answer 1

I think that you have added bguru_options option before. If bguru_options already exists, add_option() does nothing. To modify the value of existing options you should use update_option() instead.

EDIT

I confirm what I thought. You are running add_option('bguru_options', $default_options); in every admin_init. bguru_options option was added to database in the first run and subsequent calls to add_option('bguru_options', $default_options); are doing nothing.

• Use update_option() to change the value of a existent option. If the option doesn't exist, it will be created.
• Use add_option() if you really need it. For example, if you need to set autoload=no. This parameter is not accepted by update_option(). Do this preferably during plugin/theme activation
• If you need to use add_option() and you are not sure if the option already exists, use delete_option() before call add_option().

EDIT 2

I've tested your code exactly as it is and I've tested it. The default logo URL is correctly added to database in the bguru_options option and returned by get_option('bguru_options');:

$options=get_option('bguru_options');
var_dump($options['bguru_logo']);

There is no problem at all. The only drawback is that if the you leave the URL field empty, the default logo URL is not set because, I repeat, add_option() is doing nothing in subsequent calls because bguru_options option already exists.

I've tested the code and it works. If it does not work for you I will need more information. Maybe some debug log?

Anyway, I wnat to show you how get_option() support default values without the need of store default values in the database:

$default_options=array(
     'bguru_logo'=>'http://templategraphy.com/demo/businessguru/images/logo.png',
     'bguru_vimeo'=>'',
     'bguru_skype'=>'',
     'bguru_dribbble'=>'',
     'bguru_slide_one_image'=>'',
     'bguru_slide_one_heading'=>'',
     'bguru_slide_one_text'=>''
 );
 $bguru_options = get_option('bguru_options', $bguru_options_defaults);
 //Set defaults for unsaved subset in the array
 $bguru_options = wp_parse_args( $bguru_options, $bguru_options_defaults );

Answer 2

You should encode the array to json or serialize it before adding it as an option:

  add_option('bguru_options',json_encode($default_options));

or

  add_option('bguru_options',serialize($default_options));
