Display stored value in Meta Box

  • How to display stored value in Meta Box ?

    I added Meta Box with below code.

    
add_meta_box('wp_news_settings', 'News Settings', 'news_settings_html', 'news', 'normal', 'default');

    My call back function is like below

    
public function news_settings_html($post)
    {
        $wpwi_stored_meta = get_post_meta($post->ID);
        
       
        $fields = [
            'location' => '<input type="text" value="'. (!empty($wpwi_stored_meta) && $wpwi_stored_meta['location']) ? $wpwi_stored_meta['location'][0] : ''.'"  name="location" />',  
        ];
            wp_nonce_field(basename(__FILE__), 'wpwi_nonce');
            
        ?>
            <table class="form-table">
                <?php
                    foreach($fields as $key=> $field) {
                        ?>
                            <tr valign="top">
                                <th scope="row">
                                    <label for="location">
                                        <?= _e(ucfirst($key), 'textdomain');?>
                                    </label>
                                </th>
                                <td>
                                    <?= $field; ?>
                                </td>
                            </tr>
                        <?php
                    }
                ?>
            </table>
        <?php
    }

    But I am not getting Stored Value in Meta Box .

  • You are not using get_post_meta() correctly. You have only specified the ID here, which gives you all the fields for this one, but you probably only need the “location” field. Better would be:

     $wpwi_stored_meta = get_post_meta($post->ID, 'location', true);
               
        $fields = [
            'location' => '<input type="text" value="'.$wpwi_stored_meta.'"  name="location" />'  
        ];

    The foreach loop below makes little sense if you have only one field which you store in $fields anyway. You could also simplify it.

    If that doesn’t work either, you can use var_dump() to output what is in $wpwi_stored_meta.
