Wordpress主題選項文本區域不在前端顯示文本

Question

我是新來的PHP，我想在wordpress中創建一個主題選項。的主題選項其餘都工作正常，但我創造了選項3沒有顯示在前端的文字

<?php 
//register settings 
function theme_settings_init(){ 
    register_setting('theme_settings', 'theme_settings'); 
} 

//add settings page to menu 
function add_settings_page() { 
add_menu_page(__('Theme Settings'), __('Theme Settings'), 'manage_options', 'settings', 'theme_settings_page'); 
} 

//add actions 
add_action('admin_init', 'theme_settings_init'); 
add_action('admin_menu', 'add_settings_page'); 

//define your variables 
$color_scheme = array('default','blue','green',); 

//start settings page 
function theme_settings_page() { 

if (! isset($_REQUEST['updated'])) 
$_REQUEST['updated'] = false; 

//get variables outside scope 
global $color_scheme; 
?> 

<div> 

<div id="icon-options-general"></div> 
<h2><?php _e('Elegant Theme Settings') //your admin panel title ?></h2> 

<?php 
//show saved options message 
if (false !== $_REQUEST['updated']) : ?> 
<div><p><strong><?php _e('Options saved'); ?></strong></p></div> 
<?php endif; ?> 

<form method="post" action="options.php"> 

<?php settings_fields('theme_settings'); ?> 
<?php $options = get_option('theme_settings'); ?> 

<table> 

<!-- Option 1: Custom Logo --> 
<tr valign="top"> 
<th scope="row"><?php _e('Custom Logo'); ?></th> 
<td><input id="theme_settings[custom_logo]" type="text" size="36" name="theme_settings[custom_logo]" value="<?php esc_attr_e($options['custom_logo']); ?>" /> 
<label for="theme_settings[custom_logo]"><?php _e('Enter the URL to your custom logo'); ?></label></td> 
</tr> 

<!-- Option 2: Color Scheme --> 
<tr valign="top"> 
<th scope="row"><?php _e('Color Scheme'); ?></th> 
<td><select name="theme_settings[color_scheme]"> 
<?php foreach ($color_scheme as $option) { ?> 
<option <?php if ($options['color_scheme'] == $option){ echo 'selected="selected"'; } ?>><?php echo htmlentities($option); ?></option> 
<?php } ?> 
</select>      
<label for="theme_settings[color_scheme]"><?php _e('Choose Your Color Scheme'); ?></label></td> 
</tr> 

<!-- Option 3: Intro Code --> 
<tr valign="top"> 
<th scope="row"><?php _e('Intro'); ?></th> 
<td><label for="theme_settings[headline]"><?php _e('Enter your Intro Headline'); ?></label> 
<br /> 
<textarea id="theme_settings[headline]" name="theme_settings[headline]" rows="5" cols="36"><?php esc_attr_e($options['headline']); ?></textarea></td> 
</tr> 


<!-- Option 4: Tracking Code --> 
<tr valign="top"> 
<th scope="row"><?php _e('Tracking Code'); ?></th> 
<td><label for="theme_settings[tracking]"><?php _e('Enter your analytics tracking code'); ?></label> 
<br /> 
<textarea id="theme_settings[tracking]" name="theme_settings[tracking]" rows="5" cols="36"><?php esc_attr_e($options['tracking']); ?></textarea></td> 
</tr> 

</table> 

<p><input name="submit" id="submit" value="Save Changes" type="submit"></p> 
</form> 

</div><!-- END wrap --> 

<?php 
} 
//sanitize and validate 
function options_validate($input) { 
    global $select_options, $radio_options; 
    if (! isset($input['option'])) 
     $input['option'] = null; 
    $input['option'] = ($input['option'] == 1 ? 1 : 0); 
    $input['sometext'] = wp_filter_nohtml_kses($input['sometext']); 
    if (! isset($input['radioinput'])) 
     $input['radioinput'] = null; 
    if (! array_key_exists($input['radioinput'], $radio_options)) 
     $input['radioinput'] = null; 
    $input['sometextarea'] = wp_filter_post_kses($input['sometextarea']); 
    return $input; 
} 
?> 

所有其他選項都工作正常，但是當我在介紹中添加文本框它不顯示在前端的內容

<?php //show tracking code for the header 
    echo $options['headline'];?> 

請幫我

Answer 1

您直接使用在第二個選項中選擇$。

<option <?php if ($options['color_scheme'] == $option){ echo 'selected="selected"'; } ?>><?php echo htmlentities($option); ?></option> 

我認爲這是覆蓋你的第二個選項。
