Question

我搜索了为什么我的get_header()函数无法在我的插件中运行。所有可能的解决方案都说index.php文件可能已损坏。但就我而言，它的工作正常。我的错误与关于get_header()的stackexchange上解决的其他错误不同。

还请帮我介绍如何从插件文件夹中显示我的searchresult.php。如果我在其中添加任何wordpress函数，它会显示undefined function。比如get_header()，插件文件夹等。

我的代码：

<?php
get_header();

// Start the loop.
global $wpdb;
$srh = $_POST['s'];
//get_search_query();

if(!empty($srh)) {

    echo $srh;
    // Search title from table
    $sql = "SELECT * FROM wp_article WHERE title LIKE '$srh'";
    $result = $wpdb->get_results($sql) or die(mysql_error());

    if(count($result) > 0) {
        foreach($result as $results) {
            echo $results->title;
            echo $results->desc;
        }
    } else {

        echo "no ";
    }

} // submit end

?>

searchform.php

<style>
.search{
    border:0px solid #E5E5E5;
width: 100%;
height:90px;
padding:0px;    


}
.search ul li{
    list-style:none;
    padding:0px;
    display:inline-block !important;
    position:relative;
    float:none !important;
    text-align:left;

}
.widget input.search-field[type="search"] {
width:100%; 
}

</style>


<div class="search"><?php

/**
 * Template for displaying search forms in Twenty Sixteen
 *
 * @package WordPress
 * @subpackage Twenty_Sixteen
 * @since Twenty Sixteen 1.0
 */
$url = plugins_url();  
get_header();
?>

<form role="search" method="get" class="search-form" action="<?php echo $url; ?>/magicsearch/searchm.php" >
    <label>
        <span class="screen-reader-text"><?php echo _x( 'Search for:', 'label', 'twentysixteen' ); ?></span>
        <input type="search" class="search-field" placeholder="<?php echo esc_attr_x( 'Search &hellip;', 'placeholder', 'twentysixteen' ); ?>" value="<?php echo get_search_query(); ?>" name="s" title="<?php echo esc_attr_x( 'Search for:', 'label', 'twentysixteen' ); ?>" />
    </label>
    <button type="submit" class="search-submit"><span class="screen-reader-text"><?php echo _x( 'Search', 'submit button', 'twentysixteen' ); ?></span></button>
</form>
</div>

Answer 1

您是否在主题文件夹中设置了页眉和页脚.php文件？可能看起来像一个愚蠢的问题，但它已经知道会发生。

关于搜索问题，我不是100％肯定该搜索问题，但这get_search_form topic可能会有所帮助

这是一个自定义主题还是您选择的默认主题？

get_header（）函数在wordpress插件文件夹中不起作用
