Question

我有这个代码在标题中输出不同的代码片段，具体取决于我使用的页面模板。但我不能为我的生活让它发挥作用。

我基本上想要输出：

<div class="background-image" style="background-image: url('<?php echo $image[0]; ?>')"> </div>如果有人正在查看网页模板header-hero.php。

每当我这样做时，我都会在页面上看到这个输出：

Parse error: syntax error, unexpected 'is_page_template' (T_STRING), expecting '(' in /Users/Marc/Documents/Websites/www.psy-chosexualsomatics.dev/wp-content/themes/html5blank-stable/header.php on line 33

<header class="header clear" role="banner">
            <?php function check_template() {if is_page_template( 'header-hero.php' ) {
                if ( ! is_page() ) {
                    echo "<div class='background-image' style='background-image: url('" . $image[0]; "'&nbsp;</div>";
                } } } ?>
                <div class="nav_container"> <!-- logo & nav -->
                <div class="logo col-xs-12 col-md-3 col-lg-3">
                    <a href="<?php echo home_url(); ?>">
                        <!-- svg logo - toddmotto.com/mastering-svg-use-for-a-retina-web-fallbacks-with-png-script -->
                        <img src="/wp-content/uploads/2016/02/PST_LOGO_SHORT_T-1.png" alt="Logo" class="logo-img col-xs-6 col-xs-offset-3 col-md-7">
                    </a>
                </div>

                <nav class="nav col-md-6 col-md-offset-2 col-lg-6 col-lg-offset-2" role="navigation">
                    <?php html5blank_nav(); ?>
                </nav>

                <div style="clear:both;"></div>
            </div>

        </header>

您忘了将is_page_template( 'header-hero.php')放入()明确说明错误信息。

<header class="header clear" role="banner">
    <?php

    function check_template()
    {
        if (is_page_template('header-hero.php'))
        {
            if (!is_page())
            {
                echo "<div class='background-image' style='background-image: url('" . $image[0];
                "'&nbsp;</div>";
            }
        }
    }
    ?>
    <div class="nav_container"> <!-- logo & nav -->
        <div class="logo col-xs-12 col-md-3 col-lg-3">
            <a href="<?php echo home_url(); ?>">
                <!-- svg logo - toddmotto.com/mastering-svg-use-for-a-retina-web-fallbacks-with-png-script -->
                <img src="/wp-content/uploads/2016/02/PST_LOGO_SHORT_T-1.png" alt="Logo" class="logo-img col-xs-6 col-xs-offset-3 col-md-7">
            </a>
        </div>

        <nav class="nav col-md-6 col-md-offset-2 col-lg-6 col-lg-offset-2" role="navigation">
<?php html5blank_nav(); ?>
        </nav>
        <div style="clear:both;"></div>
    </div>
</header>

Wordpress：如果is_page_template为true，则输出代码
