问题描述

大家好，


我已经在我的数据库中创建了一个新表（例如/''XM_newtable''）并在其中我

有一个字段（例如/''newfield''）


我在''newfield'下输入了100个值，我需要做的是

在我插入一些代码时随机显示这些值。


我的问题是我不知道要插入什么代码

我猜这将是一个类似于下面的代码。但是

直接通往这个领域的路径是什么？如何从这个字段中随机获得结果

？


<？php

print（" $ newfield";;

我想要的最后一件事是如果该字段没有任何

条目（所以如果我拿出我放入的100个值）那么我会想要让代码打印消息对不起但没有价值可用！ ;

所有帮助总是受到赞赏。

谢谢

我用一个随机数来做这样的事情。放入一个排序字段，

将一个1到100的随机数放入其中。解析记录并根据该数字排序

。

希望我在写我的之前用Google搜索。不，它帮助了我。

Hi All,

I''ve created a new table (eg/ ''XM_newtable'') on my database and in it I
have a single field (eg/ ''newfield'')

I have entered 100 values under the ''newfield'' and what I need to do is
display these values at random wherever I insert a bit of code.

My problem is that I don''t know what bit of code to insert
I guess that it will be a code similar to below. But what would the
direct path to this field be? And how can I make the result be random
from this field?

<?php
print("$newfield");

The final thing that I would like is that if the field doesn''t have any
entries (so if I take out the 100 values that I''ve put in) then I would
like to have the code print the message "sorry but no value available!"
All help is always appreciated.
Thanks

I use a random number to do things like this. Put in a sort field and
put a random number from 1 to 100 in it. Parse the records and sort
according to that number.

Wish I had googled before I wrote mine. Nah, it helped me.

If you are in a hurry however, take a look at this.
