I\'m trying to add a new option to a theme options panel 隐藏/显示主题模板文件中的注释链接。

我可以选择显示在面板中，但有一个错误，它不起作用，并且没有php错误。我在下面的Main options code 我将选项添加为数组，并对其进行清理和验证。

和at the bottom 是根据选项设置显示/隐藏注释链接的php。

这是php逻辑问题吗？还有想法？

Main options code:

/**
* Describe the available options
**/
$vertigo_options_template = array(
array(
    \'name\' => __( \'Accent Color\', \'vertigo\' ),
    \'desc\' => __( \'Change the accent color by entering a HEX color number. (ie: <code>EE3322</code>)\', \'vertigo\' ),
    \'id\' => \'accent_color\',
    \'std\' => \'ee3322\',
    \'type\' => \'colorpicker\'
),

array(
    \'name\' => __( \'Font\', \'vertigo\' ),
    \'desc\' => __( \'Enable Hitchcock custom font (Note: this font only supports basic Latin uppercase letters, numerals, and some punctuation.)\', \'vertigo\' ),
    \'id\' => \'vertigo_font\',
    \'std\' => ( \'1\' == get_option( \'lang_id\' ) ) ? \'true\' : \'false\',
    \'type\' => \'checkbox\'
),  


/** My new Option  **/

array(
    \'name\' => __( \'Comments\', \'vertigo\' ),
    \'desc\' => __( \'Disable comment links)\', \'vertigo\' ),
    \'id\' => \'disable_comments_link\',
    \'std\' => ( \'1\' == get_option( \'lang_id\' ) ) ? \'true\' : \'false\',
    \'type\' => \'checkbox\'
),  
);

            unset( $input[$field] );
    }
}

return $input;
}

And I\'m using this in my template files to show/hide the comments template:

<?php if ( \'true\' == $vertigo_theme_options[\'disable_comments_link\'] ) { ?> 
<?php comments_template( \'\', true ); ?>
<?php } ?>

This is what the options look like in the DB called vertigo_theme_options:

a:3:{s:12:"accent_color";s:6:"EE3322";s:12:"vertigo_font";s:4:"true";s:21:"disable_comments_link";s:5:"true";}

Edit 7/25/11: This works in template file; need to call options first:

<?php $vertigo_theme_options = get_option( \'vertigo_theme_options\' ); ?>

<?php if ( \'false\' == $vertigo_theme_options[\'disable_comments_link\'] ) { ?> 
<?php comments_template( \'\', true ); ?>
<?php } ?>
