Guide to Using php Statements in dedecms

In DEDECMS, if you use the php statement, you have a {dede: php} tag that you can use. The simplest input is as follows

{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 as 1 in php, and the above statement is written as follows in php

 

<?

$numA=1;

$numB=2;

echo $numA+$numB;

?>

Does it look very similar? Look at another one with if else condition judgment

[field:global runphp='yes' name=autoindex] 

$a="<SPAN class='num active'>"; 

$b="</SPAN>"; 

$c="<(www.ofstack.com)SPAN class='num'>"; 

if (@me > 3) @me = $c.@me.$b; 

else @me = $a.@me.$b; 

[/field:global]

I won't write this in php. Next, we will look at the use of dede php tags combined with sql tags.

Output a single content in combination with SQL query

{dede:php}

$row = $dsql->GetOne('select id,typename from dede_arctype where id=2');

print_r($row);

{/dede:php}

The content of this output is

Array

(

[id] => 2

[typename] =>  Question and answer 

)

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