如何自动提交表单

时间：2017-01-28 作者：crepuslily

我正在使用一个表单插件Formcraft。用户通过两个URL访问表单，每个URL在查询字符串中传递不同的参数。表单是使用条件逻辑设置的，因此每个URL显示不同的字段。

我想要的是一个选项，用户可以单击链接，自动填充字段，并发送数据。现在，这些字段会自动填充，但用户仍需单击提交按钮。

我想知道是否可以在表单php文件的某个地方添加一个if语句，以便在填写特定字段的情况下提交表单？或者，还有其他方法可以做到这一点吗？

任何帮助都将不胜感激。谢谢

我正在添加php文件的提交表单部分：

/*Submit The Form*/
add_action(\'wp_ajax_formcraft3_form_submit\', \'formcraft3_form_submit\');
add_action(\'wp_ajax_nopriv_formcraft3_form_submit\',   \'formcraft3_form_submit\');

您可以使用javascript在几秒钟后自动提交表单。

function to_submit_form(){
    document.getElementById("myForm").submit();
}

setInterval(to_submit_form,3000);
像这样的。

我有一个客户的网站，是在他们离开另一家代理机构后我找到的。该机构使用了一个专有主题和自己的自托管页面生成器，以防止其在除他们之外的任何其他托管环境中更新或编辑。它的另一个方面是重新映射主题的URL并上载目录。因此，例如，代替WP在中查找主题文件http://domain.com/wp-content/themes/…. 它在里面找他们http://domain.com/t/….同样，对于图像上载，也可以在http://domain.com/wp-content/uploads/…, 它在里面找他们http
