dedeHow to call the first picture in the article?

Two operations are required

The first step is to modify the include/extend.func.php file, insert the function at the bottom, and query the article append table, if you need to query a picture collection or something, just change the table name

The code is as follows:

function GetFirstImg($arcid){
global $dsql;
$query= "SELECT body FROM `dede_addonarticle` where aid='$arcid'";
$row = $dsql->GetOne($query);
$preg = "/<img .*?src=[\&#39;\"](.+?)[\&#39;\"].*? alt="How to call dede the first picture in the article" >/i";
preg_match_all($preg, $row[&#39;body&#39;], $match);
//print_r($match);
return $match[1][0];
}

The second part modifies the call tag include/taglib/arclist.lib.php

The litpic field needs to be used when DreamWeaver calls the article content. This field needs to be reconstructed and find the function lib_arclistDone() function. Inside $row[litpic], add //Call the first picture of the article, non-thumbnail, if it is empty, call the thumbnail.

The code is as follows:

if(GetFirstImg($row['id'])!="")
{
$row['litpic']=GetFirstImg($row['id']);
}

The judgment is written so that when the article is called without a picture, the thumbnail display can still be selected. Dreamweaver v57 sp1 is about line 475, just add it below the $row[] array.

In this way, the original label field can also be used to call the image. If the article has the first picture, the first picture will be displayed. If not, the article thumbnail

will be called.
