dedecms {dede:php} tag usage introduction, dedecmsdede

The simplest input is as

The code is as follows Copy the code
{dede:php}

 $numA = 1;

 $numB = 2;

echo $numA + $numB;

{/dede:php}

It can be seen from the above statement that the dede:php tag can be used in the same way in PHP. The above statement is written as follows in PHP

The code is as follows Copy the code
$numA=1;
$numB=2;
echo $numA+$numB;
?>


Doesn’t it look similar? Let’s look at another one with an if else condition

Copy the code as follows
[field:global runphp='yes' name=autoindex]
$a="";
$b="
";
$c="<(www.111cn.net)SPAN class='num'>";
if (@me > 3) @me = $c. @me.$b;
else @me = $a.@me.$b;
[/field:global]

I won’t write how to write this in php. Next we will look at the use of dede php tags in combination with sql tags.


Combined with SQL query to output a single piece of content

Copy the code as follows
{dede:php}
$row = $dsql->GetOne('select id,typename from dede_arctype where id=2');
print_r($row) ;
{/dede:php}
The output content is
Array
(
[id] => 2
[typename] => Q&A
)

Isn’t it very simple? Friends who need to learn can refer to this article.
