我想创建两个报告并使用类中的两个函数将报告数据提交到数据库：这里我有两个提交按钮：＆＃34;创建ES报告＆＃34;和＆＃34;创建RP报告＆＃34;。
（1）当我点击＆＃34;创建ES报告＆＃34;时，create_es_report表单应该显示并能够填充数据并成功提交到数据库，如果错误，它应该在同一个div上显示错误。
（2）当我点击＆＃34;创建RP报告＆＃34;时，create_rp_report表单应该显示并能够填充数据并成功提交到dataabase，如果错误，它应该在同一个div上显示错误。
Rightnow，当我点击任何提交按钮时，没有显示任何内容

我的猜测是你的PHP失败并且成功选项没有触发。
我建议在你的成功选项中添加一个data.res的控制台写入，并添加一个错误选项并添加一个完整的选项，它会写一些与控制台不同的内容，这样你就可以确定jquery是否失败或者php是否失败。
作为旁注，我将create_es和create_rp函数组合为1，因为它们是相同的，除了在ajax中传递的查询字符串值。然后，您将在点击事件中调用create_report（＆＃34; es＆＃34;）和create_report（＆＃34; rp＆＃34;），并且您的ajax网址将为"check.php?proc=" + report,，其中report是您的函数参数。< / p>

您似乎也不知道如何处理PHP和AJAX。
首先更改网址E.G：
url: "check.php?proc=create_es",
到
url: "check.php?proc=create",
看看GET的check.php是如何工作的。
将type: "POST",更改为type: "GET",
现在要回复错误，只需调用php函数就会更复杂。
要返回错误，您将从create_es_report错误返回到check.php文件并将json格式返回到您的html页面，这就是为什么我说首先学习ajax。
也不要使用htmlentities我建议您使用HTMLPURIFER来补充来自恶意输入的输入。
