对于即将推出的GDPR，我正在创建一个插件，为我的客户的每个网站添加一些代码段。
我现在遇到问题的代码，应检查是否安装了Contact Form 7，以及是否存在帖子类型为'wpcf7_contact_form'且标题为'Kontakt'的帖子。如果是这样，它应该获得帖子内容并检查是否存在提交和接受字段。如果有一个提交按钮但没有接受字段，它应该将接受字符串（包括按钮短代码）与找到的提交部分连接起来，并将其替换为帖子内容。
经过一些测试后，我注意到检查是否有帖子以及是否安装了cf7。其余的不是。使用http://www.phpliveregex.com/创建的preg_match模式。我现在不知道为什么它不会催促，谢谢你事先提供任何帮助。
编辑：经过一些调试（仍然在代码中）我注意到，现在check_submit和check_acceptance函数不起作用。其余的cos现在应该运行。
代码：
<?php
add_action( 'admin_init', 'init_cf7_privacy');
function init_cf7_privacy() {
if ((check_cf7_installation()) && (find_contact_form() != "")) {
$formContent = get_contactform_content();
$acceptance = '[acceptance acceptance-842]<small>Ich habe die <a href="/datenschutzerklaerung">Datenschutzerklärung</a> zur Kenntnis genommen. Ich stimme zu, dass meine Angaben zur Kontaktaufnahme und für Rückfragen dauerhaft gespeichert werden. </small>[/acceptance]';
if (check_cf7_installation())
echo "CF7 Returned true!" . "\r\n";
echo "CF Page ID: " . find_contact_form();
if (check_submit( $formContent ))
echo "Submit Returned true!" . "\r\n";
if (check_acceptance( $formContent ))
echo "Acceptance Returned true!" . "\r\n";
//echo concatenate_acceptance_submit( $formContent, $acceptance ) . "\r\n";
echo add_acceptance( $formContent, $acceptance );
$my_post = array(
'ID' => find_contact_form(),
'post_content' => add_acceptance( $formContent, $acceptance ) ,
);
// Update the post into the database
wp_update_post( $my_post );
}
}
function check_cf7_installation() {
if (class_exists('wpcf7'))
return true;
}
function find_contact_form() {
$searchTitle = 'Kontakt';
$page = get_page_by_title( $searchTitle, OBJECT, 'wpcf7_contact_form');
return $page->ID;
}
function get_contactform_content() {
$my_postid = find_contact_form();
$post_object = get_post($my_postid);
$content = $post_object->post_content;
return $content;
}
function concatenate_acceptance_submit( $formContent, $acceptance ) {
if( preg_match('/.+\[submit\s["].+["]\].+/', $formContent, $matches ) ) {
return $acceptance . "\r\n" . "\r\n" . $matches[0];
}
}
function check_submit( $formContent ) {
if ( preg_match('/\[submit\s["].+["]\]/', $formContent) )
return true;
}
function check_acceptance( $formContent ) {
if ( preg_match('/\[acceptance\s.+\]/', $formContent) )
return true;
}
function add_acceptance( $formContent, $acceptance ) {
if ( check_submit( $formContent ) && !check_acceptance( $formContent ) ) {
if ( preg_match('/.+\[submit\s["].+["]\].+/', $formContent, $matches) ) {
$formContentRep = str_replace( $matches[0], concatenate_acceptance_submit( $formContent, $acceptance ), $formContent );
return $formContentRep;
}
}
}
成功收到preg_match函数的帖子内容和主题：
<p>Ihr Name (Pflichtfeld)<br /> [text* your-name] </p>
<p>Ihre E-Mail-Adresse (Pflichtfeld)<br />
[email* your-email] </p>
<p>Betreff<br />
[text your-subject] </p>
<p>Ihre Nachricht<br />
[textarea your-message x3] </p>
<p class="submit">[submit "tohuwabohu"]</p>
答案 0 :(得分：0)
我不确切知道为什么，但是wp_update_post（）使得chek函数无法正常工作。以下带有wpdb查询的代码现在正在运行：
<?php
add_action( 'admin_init', 'init_cf7_privacy');
function init_cf7_privacy() {
if ((check_cf7_installation()) && (find_contact_form() != "")) {
$formContent = get_contactform_content();
$acceptance = '[acceptance acceptance-842]<small>Ich habe die <a href="/datenschutzerklaerung">Datenschutzerklärung</a> zur Kenntnis genommen. Ich stimme zu, dass meine Angaben zur Kontaktaufnahme und für Rückfragen dauerhaft gespeichert werden. </small>[/acceptance]';
