Solution


I googled online for a while and found that it was very troublesome to take out the pictures inserted into the article through fckeditor. I studied it carefully for an afternoon and just started to learn the regular rules. I wrote the following function, but there must be many shortcomings. , please give me some advice. /**

* Get article pictures, and can get pictures inserted by fckeditor

* @param int $aid article ID

* @return array $imagename Image name

**/

function get_image_article ($aid) {

global $db,$dbpre;

$aid = intval($aid);

$data = array();

$sql = "select aid,acontent from {$dbpre}article where `aid`='{$aid}'";

$data = $db->get_one_record($sql); //Here is the function to get a row of records

$imagename = array();

preg_match_all('/input type="image" (.*) />/',$data,$arr);

foreach ($arr as $key => $val) {

if ($key == 1) {

foreach ($val as $k => $v) {

$imagename[] = substr($v,strrpos($v,"/")+1,-1);

}

}

}

unset ($aid,$data,$sql,$arr);

return $imagename;

}
