根据 db 中的值在 wp 页脚中动态显示代码

Question

我正在使用 wordpress 插件来显示房地产数据。当在 db 中找到某个值时，我需要在 wordpress 页脚中显示某个 sn-p 代码。细节。我已经使用以下函数显示了页脚代码：

// Adds Tucson Association of Realtors required board html to wp_footer()    
dynamically.
function wwidx_footer_script() { ?>
<div class="aztarfooter" style="text-align:center;">©2016 Tucson Association of Realtors. All rights reserved. All information deemed reliable, but Not Guaranteed. IDX information is provided exclusively for consumers' personal, non-commercial use and may not be used for any purpose other than to identify prospective properties consumers may be interested in purchasing.<br> <br><img src="https://www.weeboweb.com/wp-content/uploads/2016/10/tarlogo.gif"><br><img src="https://www.weeboweb.com/wp-content/uploads/2017/05/EHO-logo-e1494994377845.jpeg"> <img src="https://www.weeboweb.com/wp-content/uploads/2017/05/MLS_Clear-1-e1494994488609.jpg"></div>
<?php }
add_action( 'wp_footer', 'wwidx_footer_script' );

这个函数在我想要的位置和几乎想要的方式显示代码。问题是我需要让它动态化。在我的数据库中，有一个名为wp_realty_controlpanel 的表。在该表中，有一个名为controlpanel_masterdb_user 的字段。当该表中的值为"wwidx_az_tar" 时，我希望显示代码，否则不显示。您可以在这里Link 看到我想要的确切位置的 sn-p。

感谢任何帮助。

Answer 1

function wwidx_footer_script() {
    global $wpdb;
    $table_name = $wpdb->prefix . "realty_controlpanel";
    $results = $wpdb->get_row( "SELECT controlpanel_masterdb_user FROM $table_name WHERE controlpanel_masterdb_user = 'wwidx_az_tar' " );
    if( $results->controlpanel_masterdb_user == "wwidx_az_tar" ){ ?>
        <div class="aztarfooter" style="text-align:center;">©2016 Tucson Association of Realtors. All rights reserved. All information deemed reliable, but Not Guaranteed. IDX information is provided exclusively for consumers' personal, non-commercial use and may not be used for any purpose other than to identify prospective properties consumers may be interested in purchasing.<br> <br><img src="https://www.weeboweb.com/wp-content/uploads/2016/10/tarlogo.gif"><br><img src="https://www.weeboweb.com/wp-content/uploads/2017/05/EHO-logo-e1494994377845.jpeg"> <img src="https://www.weeboweb.com/wp-content/uploads/2017/05/MLS_Clear-1-e1494994488609.jpg"></div>
<?php 
    }
}
add_action( 'wp_footer', 'wwidx_footer_script' );

你能试试上面的代码吗？
