The icon needs to be displayed when calling the column at the front desk. Let’s organize it:
Step one: "System->SQL Command Tool", insert sql statement
alter table dede_arctype add imgtype varchar(<span style="color: #800080;">100</span>)
Step 2: Enter the background management file directory (default: dede directory), find line 228 under "catelog_add.php", and replace the default one with the following (added "typeimg" to the SQL statement)
<span style="color: #800080;">$in_query</span> = "<span style="color: #000000;">INSERT INTO `#@__arctype`(reid,topid,sortrank,typename,typedir,isdefault,defaultname,issend,channeltype,
tempindex,templist,temparticle,modname,namerule,namerule2,
ispart,corank,description,keywords,seotitle,moresite,siteurl,sitepath,ishidden,`cross`,`crossid`,`content`,`smalltypes`,`typeimg`)
VALUES('</span><span style="color: #800080;">$reid</span>','<span style="color: #800080;">$topid</span>','<span style="color: #800080;">$sortrank</span>','<span style="color: #800080;">$typename</span>','<span style="color: #800080;">$typedir</span>','<span style="color: #800080;">$isdefault</span>','<span style="color: #800080;">$defaultname</span>','<span style="color: #800080;">$issend</span>','<span style="color: #800080;">$channeltype</span><span style="color: #000000;">',

Step 3: Find line 36 under "catelog_edit.php" and replace the default with the following (added "typeimg" to the SQL statement)
<span style="color: #800080;">$upquery</span> = "<span style="color: #000000;">UPDATE `#@__arctype` SET

Step 4: Enter the "catalog_add.htm and catalog_edit.htm" files under the background management file directory (default: dede directory)/templets/, and then add the following code:
<span style="color: #0000ff;"><span style="color: #800000;">script </span><span style="color: #ff0000;">language</span><span style="color: #0000ff;">='javascript' </span><span style="color: #ff0000;">src</span><span style="color: #0000ff;">="js/main.js"</span><span style="color: #0000ff;">></span><span style="color: #800000;">script</span><span style="color: #0000ff;">></span></span>
And add the following code where you want to place it:

Step 5: Call the column channel tag call, so you need to change it. Enter the /include/taglib/channel.lib.php file, find line 78, and replace the following code with the default (add typeimg field query)
<span style="color: #0000ff;">if</span>(<span style="color: #800080;">$type</span>=='top'<span style="color: #000000;">)
{
</span><span style="color: #800080;">$sql</span> = "<span style="color: #000000;">SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,typeimg
From `#@__arctype` WHERE reid=0 And ishidden1 order by sortrank asc limit 0, </span><span style="color: #800080;">$line</span> "<span style="color: #000000;">;
}
</span><span style="color: #0000ff;">else</span> <span style="color: #0000ff;">if</span>(<span style="color: #800080;">$type</span>=='son'<span style="color: #000000;">)
{

}</span>
The last step: call it at the front desk

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
