1. You can set a field in the database to feature_img display, there is a display, no will not show the scatter

2. Use a regular match in the HTML src

//@$content:string,如果是使用所见即所得文本编辑器，这个就是你的post过来的文章内容//@matches:stringpreg_match_all('//i',$content,$matches);$feature_img = $matches[0]//取得图片的url，存入数据库//echo $matches[0];

Save the picture to a different field.

If it is uploaded separately, you can add a field, if it is written with a rich text editor, you can also configure the file is uploaded to where, it is necessary to put a field or a separate field to see you are not too much trouble
