How to add php code to the dede template

How to add php code to the dreamweaver dede template?

1. Embed php in the template page

Recommended learning: 梦Weavercms

For example:

{dede:name runphp='yes'}
    $str = "hello";
    @me = $str;
    @me .= "world"
{/dede:name}

Finally The output result is hello world

In fact, "name" is an arbitrarily defined name, and the value after "@me=" is the value ultimately used for output. I will use it instead of echo (if echo is used directly , an error is reported when the template is generated, this is where it is limited, alas).

2. Reference php files

If you want to use PHP in the include file, add source='value'

{dede:include runphp='yes' source='value' file=''/}

The specifications for PHP writing are:

1. There is no need to add the 8ad468a67d1f3ae163e374a5b0a90a93 symbol in PHP coding;

2. If you want to process the value of the current tag (the first case above), use @me to represent the current The value;

3. If you directly introduce PHP and want to obtain the value after running, you must use $DedeMeValue to represent the value finally returned after running this PHP (so HTML mixed writing cannot be used).

For example:

{dede:field runphp='yes'}
$aaa=200;
$DedeMeValue=100;
$DedeMeValue += $aaa;
{/dede:field}

is equivalent to:

{dede:field runphp='yes'}
$aaa = 200;
@me=100;
@me += $aaa;;
{/dede:field}

The final return result is: 300

For example: {dede:list perpage='10'}

[field:id runphp="yes"]
$dsql = new DedeSql(false);
$a="select a.address FROM xudaoshan_addonarticle as a where a.aid=@me";
$arcRow = $dsql->GetOne($a);
@me=''.$arcRow[address].'';
[/field:id]
{/dede:list}
