primefaces submit a form to save
提问by Ali Yucel Akgul
I have code snippet as follows:
我有如下代码片段：
<h:form>
<p:panel id="projectLabel" header="Yeni Proje" style="margin-bottom:10px;">
<p:messages id="messages" />
<h:panelGrid columns="2">
<h:outputLabel for="projectname" value="Proje Ad? :" />
<p:inputText id="projectname" value="" label="ProjectName">
<f:validateLength minimum="2" />
</p:inputText>
<p:message for="projectname" />
<h:outputText value="" />
<h:outputLabel for="sector" value="Sekt?r :" />
<p:inputText id="sector" value="" label="Sector"/>
<p:message for="sector" />
<h:outputText value="" />
<center>
<p:commandButton ajax="false" value="Kaydet" icon="ui-icon-disk" action="#{createProject.create()}" />
</center>
</h:panelGrid>
</p:panel>
</h:form>
What I would like to do is, when user clicks on save button, all entries of form will be triggered to a java class to save the database. How can I do that?
我想做的是，当用户点击保存按钮时，表单的所有条目都会被触发到一个java类来保存数据库。我怎样才能做到这一点？

This is backed-bean
这是支持豆
@ManagedBean(name="saveData")
@ViewScoped
public class SaveData{
public SaveData(){}
private String projectName;
private String sector;
//getters setters
public void save(){
// you have your data here
}
}
And this is the html
这是 html
<p:panel id="projectLabel" header="Yeni Proje" style="margin-bottom:10px;">
<p:messages id="messages" />
<h:panelGrid columns="2">
<h:outputLabel for="projectname" value="Proje Ad? :" />
<p:inputText id="projectname" value="#{saveData.projectName}" label="ProjectName">
<f:validateLength minimum="2" />
</p:inputText>
<p:message for="projectname" />
<h:outputText value="" />
<h:outputLabel for="sector" value="Sekt?r :" />
<p:inputText id="sector" value="#{saveData.projectName}" label="Sector"/>
<p:message for="sector" />
<h:outputText value="" />
<center>
<p:commandButton ajax="false" value="Kaydet" icon="ui-icon-disk" action="#{saveData.save}" />
</center>
</h:panelGrid>
</p:panel>
</h:form>
