新项目流程4--快捷函数

在 根目录/index.php 中倒入自定义函数

//倒入自定义函数
include_once "./protected/functions.php";

在 根目录/protected 下建立自定义函数function.php

常用函数：

function ASSWWW(){
    return Yii::app()->request->baseUrl.'/assets/www/';
}

function ASSADM(){
    return Yii::app()->request->baseUrl.'/assets/adm/';
}

function params($str){
    return Yii::app()->params[$str];
}

function gCid(){//get controller id
    return Yii::app()->controller->id;
}

function gUid(){//get user id
    return Yii::app()->user->id;
}
function gUname(){
    return Yii::app()->user->name;
}


function p($arr){
    echo '<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />';
    echo '<pre>';
    print_r($arr);
    echo '</pre>';
}

function v($arr){
    echo '<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />';
    echo '<pre>';
    var_dump($arr);
    echo '</pre>';
}

function alert($mess, $returnUrl=FALSE){
    echo '<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />';
    echo '<script type="text/javascript">';
    echo 'alert("'.$mess.'");';
    if (!$returnUrl) {
        echo 'history.back();';//后退不刷新
    }else{
        echo 'window.location="'.$returnUrl.'";';
    }
    echo '</script>';
}

function gBackUrl(){
    return Yii::app()->request->urlReferrer;
}

设置url美化

隐藏index.php

根目录下设置

RewriteEngine on
# if a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# otherwise forward it to index.php
RewriteRule . index.php
