Question

我对PHP知之甚少。我正在为我的Wordpress主题创建一个设置页面。我想用index.php中的文本框更改index.php中的文本。我尝试了太多方法。我在index.php中的tag中分配了name，id，value就像在我的functions.php源代码中的aboutustitle一样。但我没有这样做。我怎样才能做到这一点？

我的代码在这里

<?php
// create custom plugin settings menu
add_action('admin_menu', 'my_cool_plugin_create_menu');

function my_cool_plugin_create_menu() {

//create new top-level menu
add_menu_page('Yankı Tema Ayarlar', 'Tema Ayaları', 'administrator', __FILE__, 'my_cool_plugin_settings_page' , plugins_url('/images/icon.png', __FILE__) );

//call register settings function
add_action( 'admin_init', 'register_my_cool_plugin_settings' );
}


function register_my_cool_plugin_settings() {
//register our settings
register_setting( 'my-cool-plugin-settings-group', 'aboutustitle' );
register_setting( 'my-cool-plugin-settings-group', 'some_other_option' );
register_setting( 'my-cool-plugin-settings-group', 'option_etc' );
}

function my_cool_plugin_settings_page() {
?>
<div class="wrap">
<h1>Tema Ayarları</h1>
    <p>Tema ayarlarınızı buradan düzenleyebilirsiniz</p>

<form method="post" action="options.php">
    <?php settings_fields( 'my-cool-plugin-settings-group' ); ?>
    <?php do_settings_sections( 'my-cool-plugin-settings-group' ); ?>
    <table class="form-table">
        <h2>Hakkımızda Kısmı</h2>
        <tr valign="top">
        <th scope="row">Başlık</th>
        <td><input type="text" name="aboutustitle" value="<?php echo esc_attr( get_option('aboutustitle') ); ?>" /></td>
        </tr>

        <tr valign="top">
        <th scope="row">Açıklama</th>
        <td><input type="text" name="some_other_option" value="<?php echo esc_attr( get_option('some_other_option') ); ?>" /></td>
        </tr>
    </table>

    <?php submit_button(); ?>

</form>
</div>
<?php } ?>

Answer 1

您可以使用以下方法在Wordpress中回显选项：

<p><?php echo get_option( 'option_name' ); ?></p>

Answer 2

不知道你到底意味着什么

但是如果你想要包含一些东西，你可以使用这个

<?php include 'functions.php';?>

例如这是我的索引php

<!DOCTYPE html>
<html>
<body>

<h1>Welcome to my home page!</h1>
<?php include 'functions.php';
echo "I have a $color $car.";
?>

</body>
</html>

并在我的函数php

<?php     
$color = "red"
$car = "BMW" ?>

所以输出是

I have a red BMW
