ThinkPHP

ThinkPHP自身提供了success方法与error方法用于实现带提示信息的页面跳转功能,可实现添加数据后显示提示信息并跳转的效果。success 方法用于操作成功后的提示,error 用于操作失败后的提示,二者使用方法完全一致,下面以success 方法来进行说明。
1、success方法
 
success方法语法如下:
success(message, ajax) 
参数说明message可选。页面提示信息。ajax可选。是否AJAX 方式提交,默认为false 。
如果是AJAX 方式提交的话,success 方法会调用ajaxReturn 方法返回信息。

success方法实例:

public function insert(){
// 省略部分其他代码
if($lastInsId = $Dao->add()){
// 页面跳转目标地址
$this->assign("jumpUrl","index");
$this->success("插入数据id 为:$lastInsId");
}else{
header("Content-Type:text/html; charset=utf-8");
exit($Dao->getError().'[<AHREF="javascript:history.back()">返回</A>]');
}
}

success 模板
 
success 方法默认调用公共目录即TPL/Public/ 下的success.html 模板。在该模板中,接收如下模板变量:
 
模板变量说明:
$waitSecond跳转等待时间,单位为秒,默认success 1 秒,error 3 秒。
$jumpUrl跳转目标页面地址,默认为$_SERVER["HTTP_REFERER"] (本操作前一页)。
$msgTitle操作标题。注:赋值该变量不会生效,success 会取语言包里_OPERATION_SUCCESS_ 配置信息,error 取_OPERATION_FAIL_ 配置信息。
$message页面提示信息。
$status操作状态,默认1 表示成功,0 表示失败,具体还可以由项目本身定义规则。
 
success 实际仍是调用display() 方法输出success.html 模板。因此可以根据实际情况对success.html 模板进行修改如添加更多信息提示或者进行CSS 美工设置等以满足实际需求,上面这些模板变量只是一些参考变量。
 
$jumpUrl 变量说明:
$jumpUrl 变量如果不存在,默认跳转地址是$_SERVER["HTTP_REFERER"] ,一些常见的跳转页面写法参考:
 

// 本模块其他方法如index 方法
$this->assign("jumpUrl","index");
// 带上参数
$this->assign("jumpUrl","index/section/".$section);
//其他模块
$this->assign("jumpUrl","__APP__/User/index");

 
如果要使用U 方法生成跳转目标地址,可在success.html 中变更URL 属性为U 方法形式:

<meta http-equiv='Refresh'content='{$waitSecond};URL={:U($jumpUrl)}'>

 
在操作中,对$jumpUrl 模板变量的赋值,相应的也要更改为与U 方法一致,详情可参考官方手册《ThinkPHPU 方法动态生成URL 地址》。
  
2、error 方法
 
error方法用法与sucess 方法完全一致,只是需要注意的是,ThinkPHP 默认配置error方法调用的仍是success.html 模板。如果需要对error 方法单独定义模板,可以修改系统默认配置ThinkPHP/Common/convention.php文件如下:

'TMPL_ACTION_ERROR' => 'Public:success',// 默认错误跳转对应的模板文件

或在项目配置里进行重新定义。
Web开发中,在需要页面跳转并显示提示信息时,可以直接使用ThinkPHP 页面跳转提供的上述success 与error 方法。如果不需要提示而是直接重定向页面时,可参考手册《ThinkPHP redirect 重定向》部分。

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.
