Question

extract( $_POST );

    // determine whether phone number is valid and print
    // an error message if not
    if ( !@ereg( "^[0-9]{3}-[0-9]{7}$", $phone))
    {
        echo( "<SCRIPT LANGUAGE='JavaScript'>
        window.alert('Please insert a valid phone number with (xxx-xxxxxxx) format.')
        window.location.href='';
        </SCRIPT>");
    }
else if (!@preg_match('/^(?=.*\d{3,})(?=.*[A-Za-z]{5,})[0-9A-Za-z!@#$%]{8,32}$/', $pass))
    {
        echo("<SCRIPT LANGUAGE='JavaScript'> 
        window.alert('Password must be at least 8 characters long and must contain at least 1 number and 1 letter')
        window.location.href='';
        </SCRIPT>");
    }

我不确定上面的编码有什么问题，但我似乎无法获得正确的密码值？它会一直显示相同的错误消息

如果您使用这些条件完全 8个字符，那么您需要这样的内容：

var item = {
  "_id": {
    "$oid": "asdf976"
  },
  "Categories": [{
    "mainmodels": [{
      "submodels": [{
          "price": "2000",
          "submodelname": "lumia021",
          "Remainingphones": "0",
          "Bookedphones": "0",
          "Numofphones": "10"
        }, {
          "price": "2000",
          "submodelname": "lumia341",
          "Remainingphones": "5",
          "Bookedphones": "5",
          "Numofphones": "10"
        }

      ],
      "Status": "Active",
      "modelname": "lumia",
      "fromdate": "2016-04-01T16:39:12.051Z",
      "todate": "2016-04-31T19:19:44.051Z"
    }],
    "brand": "nokia"
  }],
  "rank": "1",
  "name": "first"
};
var modal = {
  custid: '1',
  packcode: '22'
};
Object.assign(item, modal);
// Note: Just using JSON for *display*
document.body.innerHTML =
  "<pre>" + JSON.stringify(item, null, 2) + "</pre>";

你的正则表达式意味着什么？

^(?=.*\d{3,})(?=.*[A-Za-z]{5,})[0-9A-Za-z!@#$%]{8,32}$

正则表达式细分

^ #Start of string
  (?=.*\d{3,}) #Match at least 3 consecutive digits anywhere in string
  (?=.*[A-Za-z]{5,}) #Match at least 5 consecutive characters from the set anywhere in string
  [0-9A-Za-z!@#$%]{8,32} #Ensure that length of string is in between 8 and 32
$ #End of string

这将给出你想要的东西（按你在问题中描述的那样）

(?=.{8,})(?=.*[A-Z])(?=.*[a-z])(?=.*[0-9])

正则表达式细分

(?=.{8,}) #Ensure that string is of at least length 8 
(?=.*[A-Z]) #Match a single capital letter anywhere in string
(?=.*[a-z]) #Match a single small letter anywhere in string
(?=.*\d) #Match a single digit anywhere in string

正则表达式PHP，密码长度为8，至少有1个大写字母，数字为nd字母
