dedecms中使用php语句指南,dedecmsphp语句指南

在DEDECMS中,使用php语句的话,本身是有{dede:php}标签可以使用的,最简单的输入如

复制代码 代码如下:


{dede:php}

  $numA = 1;

  $numB = 2;

  echo $numA + $numB;

{/dede:php}

从上面语句可以看出dede:php标签可以名符其实的让在php中一样的用法,上面语句在php写法如下

复制代码 代码如下:


$numA=1;
$numB=2;
echo $numA+$numB;
?>

是不是看上去很像啊,再看一个再有if else 条件判断的

复制代码 代码如下:


[field:global runphp='yes' name=autoindex]
$a="";
$b="
";
$c="";
if (@me > 3) @me = $c.@me.$b;
else @me = $a.@me.$b;
[/field:global]

这个在php中写法我就不写了,下面我们要看dede php标签结合起来sql标签使用。

结合SQL查询输出单条内容

复制代码 代码如下:


{dede:php}
$row = $dsql->GetOne('select id,typename from dede_arctype where id=2');
print_r($row);
{/dede:php}

这个输出的内容是

复制代码 代码如下:


Array
(
[id] => 2
[typename] => 问答
)

是不是很简单啊,有需要学习的朋友可以参考一下本文章哈。
