php - 创建具有显示/隐藏功能的 PHP 表单

我想创建两个报告,并使用类中定义的两个函数将报告数据提交到数据库:这里我有两个按钮:“创建 ES”和“创建 RP”。

现在,我的表单工作正常,我可以成功插入数据,但问题是当我填写表单数据后单击提交时,内容隐藏并显示第一个 div 内容“cs_content”,我再次需要onclick再次提交。

谁能给出解决方案吗?

要求:

当我点击“创建 CS”时,我应该能够成功填写表单并提交数据,并在“cs_content”内显示一条消息,如果出现任何表单输入错误,错误应显示在“cs_content”内。

当我点击“创建 RP”时,我应该能够成功填写表单并提交数据,并在“rp_content”内显示一条消息,如果出现任何表单输入错误,错误应显示在“rp_content”内。

最佳答案

首先1)

您需要 JavaScript 代码来处理此表单验证,例如:

$("form").submit(function(){
// Your validation code
if(validation not satisfied){
return false;
}
});

2) 检查表单是否处于事件状态,并在提交后使该表单处于事件状态。你的 HTML 应该像这样

<body>
<div class="container2">
<div style="margin:0px 0px;padding:3px 217px;overflow:hidden;">
<div id="cs" style="float:left;margin:0px 0px;padding:7px;"><input type="button" value="CREATE CS"></div>
<div id="rp" style="float:left;margin:0px 0px;padding:7px;"><input type="button" value="CREATE RP"></div><br>
</div>
<?php $active_form = (is_first_form_checked)?'first_form':'second_form'; ?>
<div id="cs_content" style="<?php echo ($active_form == 'first_form')?'display:none;':''; ?>"> <?php $report->create_cs_report(); ?> </div>
<div id="rp_content" style="<?php echo ($active_form == 'second_form')?'display:none;':''; ?>"> <?php $report->create_rp_report(); ?> </div>
</div>
