WordPress的錯誤：警告非法偏移

Question

我正在WordPress的目錄網站，當我嘗試我得到這個錯誤的搜索選項：

警告：非法串偏移「場」在/ home/dalilouk /public_html/wp-content/themes/directory/header.php on line 27

警告：/home/dalilouk/public_html/wp-content/themes/directory/header.php在線的非法字符串偏移「字段」 33

而搜索的結果總是「找不到」。

這是header.php中從第27行的代碼：

<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"), 
     locInput = $("#dir-searchinput-location"), 
     locInputID = $("#dir-searchinput-location-id"); 

    catInput.autocomplete({ 
     minLength: 0, 
     source: categories, 
     focus: function(event, ui) { 
      var val = ui.item.label.replace(/&amp;/g, "&"); 
       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); 
      catInputID.val(ui.item.value); 
      return false;

    }).data("ui-autocomplete")._renderItem = function(ul, item) {

    var catList = catInput.autocomplete("widget");

    catInput.click(function(){

     catInputID.val('0'); 
     catInput.autocomplete("search", ""); 
    }); 

    locInput.autocomplete({

});

請幫我解決這個問題。

它不是PHP源代碼。您只是在瀏覽器中打開該PHP，所以您發佈的是PHP腳本輸出。您必須在某個編輯器中打開真正的.php文件，並向我們顯示源代碼:)

通過您的問題 - 這不是錯誤，它關於調用變量的警告，它並未設置在某個點上。所以你的腳本仍然有效，但可能你的表單有錯誤的域名發送，所以你的PHP腳本無法找到你想要搜索的數據，因爲找不到那個特定的變量。
