Add pictures to dedecms backend column-php手册-php.cn

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>)

Copy after login

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><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>

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 ishidden<>1 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><span style="color: #0000ff;">if</span>(<span style="color: #800080;">$typeid</span>==0) <span style="color: #0000ff;">return</span> ''<span style="color: #000000;">;
        </span><span style="color: #800080;">$sql</span> = "<span style="color: #000000;">SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,content,typeimg
          From `#@__arctype` WHERE reid='</span><span style="color: #800080;">$typeid</span>' And ishidden<>1 order by sortrank asc limit 0, <span style="color: #800080;">$line</span> "<span style="color: #000000;">;
    }
    </span><span style="color: #0000ff;">else</span> <span style="color: #0000ff;">if</span>(<span style="color: #800080;">$type</span>=='self'<span style="color: #000000;">)
    {
        </span><span style="color: #0000ff;">if</span>(<span style="color: #800080;">$reid</span>==0) <span style="color: #0000ff;">return</span> ''<span style="color: #000000;">;
        </span><span style="color: #800080;">$sql</span> = "<span style="color: #000000;">SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,typeimg
            FROM `#@__arctype` WHERE reid='</span><span style="color: #800080;">$reid</span>' And ishidden<>1 order by sortrank asc limit 0, <span style="color: #800080;">$line</span> "<span style="color: #000000;">;
    }</span>

The last step: call it at the front desk

        {dede:channel type='self' typeid='15' row='8' currentstyle="<li><a href='~typelink~' class='thisclass'>~typename~</a> </li>"<span style="color: #000000;">}
