解析错误：语法错误，意外'endforeach'（T_ENDFOREACH）

标签： php wordpress

我正在尝试从本教程的代码中为WordPress“category.php”创建一个页面：http://scratch99.com/wordpress/wp-seo/siloing/

我目前的主题（由Themeforest提供的Sociallyviral）没有页面“category.php”，所以我创建了一个并添加了下面的代码：

作者注： “代码看起来应该如下所示。注意，你不能只是完全使用这个代码 - 它需要适合你的主题，以便包装div等类匹配你的主题的其余部分，并选择样式“起来。

// work out category id, then see if there are any subcategories
$main_cat_ID = get_query_var( 'cat' );
$subcats = get_categories( array( 'parent' => $main_cat_ID, 'hide_empty' => 0 ) );

// if it is page 1
if ( $paged < 2 ) :

    // show the category description
    echo category_description();

    // if there are subcategories, loop through and show them
    if ( count( $categories ) > 0 ) :
        foreach ( $subcats as $category ) : ?>    
            <div class="subcategory">
                <h2><a class="subcategory-link" href="<?php echo get_category_link( $category->term_id ); ?>">
                <?php echo $category->name; ?></a></h2>
                <?php echo wpautop( $category->description ); ?>
            </div>
        <?php
       endforeach;
    endif;

    // get sticky posts and show them if they exist
    $args = array( 'category__in' => $main_cat_ID, 'include' => get_option( 'sticky_posts' ) );
    $myposts = get_posts( $args );
    if ( count( $myposts ) > 0 ) :
        foreach ( $myposts as $value ) : ?>
        <div class="sticky">
            <h3>
                <a href="<?php echo get_permalink( $value->ID ); ?>" rel="bookmark"
                title="<?php echo $value->post_title; ?>"><?php echo $value->post_title; ?></a>
            </h3>
            <div class="entry-content">
            <?php 
            // if there is an excerpt, use it, otherwise roll our own (get_the_excerpt won't work outside the loop)
            if ( $value->post_excerpt ) : 
                echo wpautop( $value->post_excerpt );
            else :
                $sjc_excerpt = explode( '<!--more-->', $value->post_content ); 
                if ( count( $sjc_excerpt ) >= 2 ) :
                    echo wpautop( strip_tags( $sjc_excerpt[0] ) );
                else :
                    echo wpautop( implode ( ' ', array_slice( explode( ' ', strip_tags( $sjc_excerpt[0] ) ), 0, 45 ) ) . ' ...' );
                endif;
            endif; ?>
            </div>
        </div>
        <?php
        endforeach;
    endif;

// pages 2 and onwards don't worry about cat desc or stickies, but link to main cat page
else : ?>
        <p>For an introduction to this topic and our latest articles, please see the main 
        <a href="<?php echo get_category_link( $main_cat_ID ); ?>"><?php single_cat_title(); ?></a> page.</p>
<?php
endif;

// if we have any posts in the main loop (no stickies there)
if ( have_posts() ) : ?>

    <ul class="other-posts">

    <?php /* Start the Loop */ ?>
    <?php while ( have_posts() ) : the_post(); ?>

        <li><a href="<?php the_permalink() ?>" rel="bookmark"
        title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></li>

    <?php endwhile; ?>
    </ul>

    <?php 
    // you need to replace this with whatever your theme uses!
    sjc_content_nav( 'nav-below' ); 

// if no posts, and also no stickies and no categories, go with no results
elseif ( count( $myposts ) == 0 && count( $subcats ) == 0 ) : 

    get_template_part( 'no-results', 'archive' ); 

endif;

如有必要，请在我的主题文件“archive.php”下面

当我尝试打开类别页面时出现此错误：

“第20行上的/wp-content/themes/sociallyviral/category.php中的解析错误：语法错误，意外'endforeach'（T_ENDFOREACH）”

此语法错误已解决！

谢谢大家！

祝你好运！

您错过了文件开头的<?php标记。

没有它，第一段代码，解析器将解析以下代码为php：

        echo get_category_link( $category->term_id );
        echo $category->name;
        echo wpautop( $category->description );
   endforeach;
endif;

正如您所看到的，第一件事（在三个echo旁边）是endforeach;，这是解析器抛出错误的地方。

作者说明如下：“......它需要适合您的主题，以便包装div 的类等等与你主题的其余部分相匹配，挑选出的风格。“

这意味着，根据您和您的模板需求，您需要在代码中使用<div>和class addributes提供style。详细地说，您应该应用模板使用的类来应用所需的布局。您应该对模板使用的类进行某种形式的引用（可能是something like this）。您可以在哪里查看要使用的类。

This是引导程序的参考 - 只是为了让你了解你的目标。

答案 1 :(得分：0)

在代码的开头加上一个php标记

<?php    // show the category description
echo category_description();

// if there are subcategories, loop through and show them
if ( count( $categories ) > 0 ) :
    foreach ( $subcats as $category ) : ?>    
        <div class="subcategory">
            <h2><a class="subcategory-link" href="<?php echo get_category_link( $category->term_id ); ?>">
            <?php echo $category->name; ?></a></h2>
            <?php echo wpautop( $category->description ); ?>
        </div>
    <?php
   endforeach;
endif;

// get sticky posts and show them if they exist
$args = array( 'category__in' => $main_cat_ID, 'include' => get_option( 'sticky_posts' ) );
$myposts = get_posts( $args );
if ( count( $myposts ) > 0 ) :
    foreach ( $myposts as $value ) : ?>
    <div class="sticky">
        <h3>
            <a href="<?php echo get_permalink( $value->ID ); ?>" rel="bookmark"
            title="<?php echo $value->post_title; ?>"><?php echo $value->post_title; ?></a>
        </h3>
        <div class="entry-content">
        <?php 
        // if there is an excerpt, use it, otherwise roll our own (get_the_excerpt won't work outside the loop)
        if ( $value->post_excerpt ) : 
            echo wpautop( $value->post_excerpt );
        else :
            $sjc_excerpt = explode( '<!--more-->', $value->post_content ); 
            if ( count( $sjc_excerpt ) >= 2 ) :
                echo wpautop( strip_tags( $sjc_excerpt[0] ) );
            else :
                echo wpautop( implode ( ' ', array_slice( explode( ' ', strip_tags( $sjc_excerpt[0] ) ), 0, 45 ) ) . ' ...' );
            endif;
        endif; ?>
        </div>
    </div>
    <?php
    endforeach;
endif;

    // pages 2 and onwards don't worry about cat desc or stickies, but link       to main cat page
   else : ?>
    <p>For an introduction to this topic and our latest articles, please see the main 
    <a href="<?php echo get_category_link( $main_cat_ID ); ?>"><?php single_cat_title(); ?></a> page.</p>

<ul class="other-posts">

<?php while ( have_posts() ) : the_post(); ?>

    <li><a href="<?php the_permalink() ?>" rel="bookmark"
    title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></li>

<?php endwhile; ?>
</ul>

<?php 
// you need to replace this with whatever your theme uses!
sjc_content_nav( 'nav-below' ); 

 // if no posts, and also no stickies and no categories, go with no results
  elseif ( count( $myposts ) == 0 && count( $subcats ) == 0 ) : 

  get_template_part( 'no-results', 'archive' ); 

 endif;

你的问题将会解决。
