Question

完全难倒。我在用户个人资料页面上有一个复选框，但它拒绝更新。它甚至不是数组设置值或任何东西，只是从不设置...似乎没有数据传递给post值...

根据@RST更新，现在按@ simon-pollard

更新

   // This will show below the color scheme and above username field
add_action( 'profile_personal_options', 'extra_profile_fields' );
add_action( 'personal_options_update', 'update_field_value' ); 
add_action( 'edit_user_profile_update', 'update_field_value' );

function extra_profile_fields( $user ) {
    // get the value of a single meta key
    $user_id =  $user->ID;
    echo "user id: " . $user_id . "<br/>";
    $meta_value = get_user_meta( $user->ID, 'emailPrefs', true ); // $user contains WP_User object
    // do something with it.
  echo "checked value: " . $meta_value. "<br/>";
    ?> 
    <h2>Email Settings</h2>
    <table class="form-table">
    <th scope="row" id="lbl-subtitle" for="email-settings">Email on Timer Reset</th>
    <td><fieldset>
<form method='post' action="profile.php">

    <input type="checkbox" id="email-settings" name='email-settings'
<?php if ($meta_value == '1'){ echo 'checked'; } ?> value ="<?php echo $meta_value?>" />

    </form>
            <?php submit_button(); ?>
    </td>
    </fieldset>
    </table>
    <?php


}

function update_field_value($user) {

 $user_id =$user->ID;

    if (isset($_POST['email-settings']) && $_POST['email-settings'] == 'on') { 
        update_user_meta( $user_id, 'emailPrefs', '1'); 
    } else { 
        update_user_meta( $user_id, 'emailPrefs', NULL); 
    }


}

Answer 1

谢谢@Simon。在他的帮助下，我看到在该更新挂钩上无法访问$user对象，这意味着user_meta从未更新过。为了解决这个问题，我创建了一个隐藏的表单字段来存储我的userID，以便它可以作为post变量使用。

以下是最终守则：

// This will show below the color scheme and above username field
add_action( 'profile_personal_options', 'extra_profile_fields' );
add_action( 'personal_options_update', 'update_field_value' ); 
add_action( 'edit_user_profile_update', 'update_field_value' );

function extra_profile_fields( $user ) {
    // get the value of a single meta key
    $user_id =  $user->ID;
    echo "user id: " . $user_id . "<br/>";
    $meta_value = get_user_meta( $user->ID, 'emailPrefs', true ); // $user contains WP_User object
    // do something with it.
  echo "checked value: " . $meta_value. "<br/>";
    ?> 
    <h2>Email Settings</h2>
    <table class="form-table">
    <th scope="row" id="lbl-subtitle" for="email-settings">Email on Timer Reset</th>
    <td><fieldset>
<form method='post' action="profile.php">
 <input type='hidden' name="user_id" value="<?php echo $user_id ?>" />
    <input type="checkbox" id="email-settings" name='email-settings'
<?php if ($meta_value == '1'){ echo 'checked'; } ?> />

    </form>
            <?php submit_button(); ?>
    </td>
    </fieldset>
    </table>
    <?php


}

function update_field_value($user_id) {

$user_id = $_POST['user_id'];
// echo $user_id;

// echo $_POST['email-settings'];

// wp_die();

    if ( isset($_POST['email-settings'], $_POST['user_id'] ) && $_POST['email-settings'] == 'on') { 
        update_user_meta( $user_id, 'emailPrefs', '1'); 
    } else { 
        update_user_meta( $user_id, 'emailPrefs', NULL); 
    }


}
