问题描述
我一直在为我的 worpress 站点离线处理此代码错误.
<块引用>解析错误:语法错误，C:\Users\guyzer\Desktop\InstantWP_4.3\iwpserver\htdocs\wordpress\wp-content\themes\thesis_182\custom\custom_functions.php 中第 169 行出现意外的["
行代码错误第 169 行: $post_date = explode(" ", $post_event)[0];
在实时站点上，站点正在运行，但是当我使用复制器复制实时站点并传输到离线或其他服务器时，总是会发生此错误，从而导致站点关闭.希望你能帮我解决这个错误！
以下是错误的完整代码:
<div class="tab-sidebars"><h1><a href="<?php echo get_site_url()?>/gigs">GIGS</a></h1><h3><a href="<?php echo get_site_url()?>/gigs/today">•今天</a></h3><h3><a href="<?php echo get_site_url()?>/gigs/weeks">•周<h3><a href="<?php echo get_site_url()?>/gigs/month">•月<div id="gigs-carousel" class="post-container"><a class="buttons prev" href="#"></a><div class="viewport"><ul class="overview" style="width:9999px !important"><?php全球 $post;$today = getdate();$args = array( 'category_name' => 'gigs','post_type' =>'邮政'，'meta_key' =>custom_event_date，'orderby' =>元值，'订单' =>'ASC','showposts' =>'99');$the_query = new WP_Query($args);while($the_query->have_posts()) :$the_query->the_post();$post_id = $post->ID;$post_event = get_post_meta($post_id, 'custom_event_date', true);$post_date =explode(" ", $post_event)[0];$post_time =explode(" ", $post_event)[1];$post_day =explode("-", $post_date)[2];$post_permalink = get_permalink($post_id);$thumbnail_src = wp_get_attachment_image_src(get_post_thumbnail_id($post_id), 'thumbnail');$date_now = date("Y-m-d H:i");$date_compare = $post_event;$date_result = strtotime($date_compare) - strtotime($date_now);$current_month = date("m");$event_month = expand("-", $post_date)[1];if($date_result > 0 && $current_month == $event_month) :?><li style="background-image:url(<?php echo $thumbnail_src[0]?>)"><div class='post-day'><?php echo $post_day?></div><a class='post-item' href="<?php echo $post_permalink?>"><div class='post-title'><?php echo get_the_title();?></div><div class='post-sub'><?php echo convert_time($post_time)?></div><div class='post-excerpt'><?php the_excerpt();?></div></a><?php万一;终了；wp_reset_postdata();?></div><!-- .viewport --><a class="下一个按钮" href="#"></a></div><!-- #gigs-carousel -->
$post_date = explode(" ", $post_event)[0];您可能正在尝试在不支持它的 PHP 版本上使用数组取消引用功能.它仅适用于 PHP 5.4+ 版本.
来自 PHP 手册:
<块引用>从 PHP 5.4 开始，可以直接对函数或方法调用的结果进行数组解引用.之前只能使用临时变量.
正如它所说，您必须在旧版本的 PHP 上使用临时变量:
$temp = expand(" ", $post_event);$post_date = $temp[0];类似地改变所有的出现.
或者，您可以使用 list() 在一行中完成(不过会降低可读性):
即可以替换:
$post_date =explode(" ", $post_event)[0];$post_time =explode(" ", $post_event)[1];这样:
list($post_date, $post_time) = expand(" ", $post_event);但是，使用临时变量并手动分配值会更简洁易读.
I've been working on this code error for my worpress site offline.
Parse error: syntax error, unexpected '[' in C:\Users\guyzer\Desktop\InstantWP_4.3\iwpserver\htdocs\wordpress\wp-content\themes\thesis_182\custom\custom_functions.php on line 169
Line code error line 169: $post_date = explode(" ", $post_event)[0];
On the live site, site is working but when i duplicate the live site using duplicator and transfer to offline or other servers this error always occurs which turn the site down. I hope you can help me solve this error!
Here is the whole code for the error:
<div class="page">

$post_date = explode(" ", $post_event)[0];
$post_time = explode(" ", $post_event)[1];
$post_day = explode("-", $post_date)[2];
$post_permalink = get_permalink($post_id);
$thumbnail_src = wp_get_attachment_image_src(get_post_thumbnail_id($post_id), 'thumbnail' );

You're probably trying to use array dereferencing feature on a PHP version that doesn't support it. It's available only on PHP 5.4+ versions.
From the PHP manual:
As of PHP 5.4 it is possible to array dereference the result of a function or method call directly. Before it was only possible using a temporary variable.
As it says, you'll have to use a temporary variable on older versions of PHP:
$temp = explode(" ", $post_event);
$post_date = $temp[0];
Change all the occurences similarly.
Or, you could use list() to do it in one line (reduces readability a bit, though):
That is, you can replace:
$post_date = explode(" ", $post_event)[0];
$post_time = explode(" ", $post_event)[1];
with this:
list($post_date, $post_time) = explode(" ", $post_event);
However, using a temporary variable and manually assigning the values is more neater and readable.
