WordPress 错误：警告非法偏移

Question

我在 wordpress 上的目录网站上工作，当我尝试搜索选项时出现此错误：

警告：第 27 行 /home/dalilouk/public_html/wp-content/themes/directory/header.php 中的非法字符串偏移“字段”

警告：第 33 行 /home/dalilouk/public_html/wp-content/themes/directory/header.php 中的非法字符串偏移“字段”

而且搜索的结果总是“没有找到”。

这是第 27 行 header.php 的代码：

<script type="text/javascript">            #line 27
jQuery(document).ready(function($) {

    {ifset $themeOptions->search->searchCategoriesHierarchical}
    var categories = [ {!$categoriesHierarchical} ];
    {else}
    var categories = [                #line 33
    {foreach $categories as $cat}
        { value: {$cat->term_id}, label: {$cat->name} }{if !($iterator->last)},{/if}
    {/foreach}
    ];
    {/ifset}

    {ifset $themeOptions->search->searchLocationsHierarchical}
    var locations = [ {!$locationsHierarchical} ];
    {else}
    var locations = [
    {foreach $locations as $loc}
        { value: {$loc->term_id}, label: {$loc->name} }{if !($iterator->last)},{/if}
    {/foreach}
    ];
    {/ifset}

    var catInput = $( "#dir-searchinput-category" ),
        catInputID = $( "#dir-searchinput-category-id" ),

    catInput.autocomplete({
        minLength: 0,
        source: categories,

                val = val.replace(/&nbsp;/g, " ").replace(/&#039;/g, "'");
            catInput.val( val );
            return false;
        },
        select: function( event, ui ) {
            var val = ui.item.label.replace(/&amp;/g, "&");
                val = val.replace(/&nbsp;/g, " ").replace(/&#039;/g, "'");
            catInput.val( val );

请帮我解决这个问题。

它不是 PHP 源代码。您刚刚在浏览器中打开了该 php，因此您发布的是该 PHP 脚本输出。您必须在某个编辑器中打开真正的 .php 文件，并向我们展示源代码:)

根据您的问题 - 这不是错误，它是关于调用变量的警告，该变量未在某些时候设置。所以你的脚本仍然有效，但可能你的表单有错误的字段名称要发送，所以你的 php 脚本无法找到你想要搜索的数据，因为找不到那个特定的变量。
