我的WordPress网站中有2个文本字段的简单表单。我创建了一个新的页面模板,并添加了以下HTML代码:
这是HTML:
<form action="<?php the_permalink(); ?>" id="customform" method="post">
Field 1: <input type="text" name="field1" id="field1">
Field 2: <input type="text" name="field2" id="field2">
<input type="submit" name="submit" id="submit">
</form>

现在我要做的就是,无论用户输入什么内容,它都将其存储到mySQL(例如,与WordPress在同一数据库中)表中test_form。
我该如何实现?
如何强制maven编译1.6兼容源
我在eclipse中用maven制作了web-app项目.将web.xml更改为使用3.0版本 - >然后更新配置,现在我无法启动tomcat.我发现我必须强制maven编译源1.6兼容,我必须添加
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.7</source>
<target>1.7</target>
<showDeprecation>true</showDeprecation>
<showWarnings>true</showWarnings>
<executable>${env.JAVA_HOME_7}/bin/javac</executable>

但日食中的有效pom是不可编辑的
所以有没有maven兼容eclipse或任何其他方式强制maven编译源1.6版本?
这是我尝试过的,不知怎的,我觉得这不对,或者这不是性能最好的应用程序,所以有更好的方法来从Map中搜索和获取重复值,或者事实上任何集合.并且可以更好地遍历集合.

public static void main(String[] args) {
Map<Integer, String> directory=new HashMap<Integer, String>();
Map<Integer, String> repeatedEntries=new HashMap<Integer, String>();
// adding data

directory.put(2,"michael");
directory.put(3,"mike");

我在数据库中调用存储过程.它的两个参数需要sql日期格式的日期和时间.
String x = new SimpleDateFormat("MM-dd-yyyy").format(new Date()) + " 00:00:00 AM";
String y = new SimpleDateFormat("MM-dd-yyyy").format(new Date()) + " 11:59:00 PM";
Date fromDate = null;
Date toDate = null;
try {
fromDate = new SimpleDateFormat("MM-dd-yyyy HH:mm:ss a").parse(x);
toDate = new SimpleDateFormat("MM-dd-yyyy HH:mm:ss a").parse(y);
} catch (ParseException ex) {
