给大伙推荐一款炒鸡好用的Thinkphp富文本编辑器

·  阅读 387

导读:

最近一直在做Thinkphp后端开发,之前都是使用layui的富文本编辑器,layui的优点是简单易用,但缺点也比较明显,就是编辑器功能比较少,无意中发现别人的项目里使用的是CKEditor富文本编辑器,感觉还阔以!下面让我们一起来学习如何使用CKEditor

Ckeditor4下载地址(本教程选择的是CKEditor 4.16版本):

ckeditor.com/ckeditor-4/…

一、在页面中引入ckeditor核心文件ckeditor.js 

<script type="text/javascript" src="ckeditor/ckeditor.js"></script>
复制代码

二、在使用编辑器的地方插入HTML控件

<textarea  id="content" name="content" cols="30" rows="2"></textarea>
复制代码

三、将相应的控件替换成编辑器代码

<script type="text/javascript">
var editor;
window.onload = function()
{
	editor = CKEDITOR.replace( 'content', {
            filebrowserImageUploadUrl : '{:url("@admin/article/uploadPic")}',//上传图片的后端URL地址
            image_previewText : '&nbsp;'///去掉图片上传预览区域显示的文字
    });
};
</script>
复制代码

四、开启上传功能(上传功能被隐藏了,所以需要开启)

 

在ckeditor/plugins/image/dialogs/image.js文件中,搜索:id:"Upload",hidden:!0,把 !0改成false

五、thinkphp后端上传文件的方法

4.10版本之后,官方文档要求图片上传成功后,返回json格式,示例如下:

上传成功返回:


{
    "uploaded": 1,
    "fileName": "demo.jpg",
    "url": "/files/demo.jpg"
}

{
    "uploaded": 1,
    "fileName": "test.jpg",
    "url": "/files/test.jpg",
    "error": {
        "message": "A file with the same name already exists. The uploaded file was renamed to \"test.jpg\"."
    }
}
复制代码

上传失败返回:

{
    "uploaded": 0,
    "error": {
        "message": "The file is too big."
    }
}
复制代码

后端上传图片的代码:

/**
    * @name='上传图片'    
    */
    public function uploadPic()
    {
		//注明:ckeditor是使用ajax上传图片,而不是用表单提交,因此不能使用request()->file()接收图片,只能用$_FILES
		$name = $_FILES['upload']['name']; 
		$size = $_FILES['upload']['size'];
		if($size  > 1024*2*1000){
			$arr= array(
				"uploaded" => 0,
				"error"    => "上传的图片大小不能超过2M"
			);
			exit(json_encode($arr));
		}
		$extension = pathInfo($name,PATHINFO_EXTENSION);
		$types = array("jpg","bmp","gif","png"); 		
		if(in_array($extension,$types)){ 
			//以日期为文件夹名,如public/uploads/20210327/
			$dateFolder = date("Ymd",time());
			$path = ROOT_PATH . 'public/uploads/'.$dateFolder.DS;
			if(!file_exists($path)){
				mkdir($path,0777,true);
			}		
			$img_name  = str_replace('.','',uniqid("",TRUE)).".".$extension; //图片名称
			$save_path = $path.$img_name; //保存路径 
			$img_path  = '/uploads/'.$dateFolder.DS.$img_name; //图片路径 
			move_uploaded_file($_FILES['upload']['tmp_name'],$save_path);   
			$arr= array(
				"uploaded" => 1,
				"fileName" => $img_name,
				"url"      => $img_path
			 );
		}else{ 
			$arr= array(
				"uploaded" => 0,
				"error"    => "图片格式不正确(只能上传.jpg/.gif/.bmp/.png类型的文件)"
			 );		 
		} 
		return json_encode($arr);
    }
复制代码

六、js里获取ckeditor里的内容

<script type="text/javascript">
var editor;
$(function() {
	editor = CKEDITOR.replace('content');
})
editor.document.getBody().getText();//取得纯文本
editor.document.getBody().getHtml();//取得html文本
</script>
复制代码

七、使用颜色插件

1、需要下载三个插件(缺一不可),下载地址:

ckeditor.com/cke4/addon/…

ckeditor.com/cke4/addon/…

ckeditor.com/cke4/addon/…

2、下载好的插件解压到ckeditor\plugins目录里

3、加载插件

方式一:在ckeditor/config.js文件中,添加插件的配置,如下:

CKEDITOR.editorConfig = function( config ) {

    ...省略前面的代码

    //加载插件
    config.extraPlugins = 'colorbutton,panelbutton,floatpanel';
}
复制代码

 方式二:在js里初始化editor时,添加插件的配置

<script type="text/javascript">
var editor;
window.onload = function()
{
	editor = CKEDITOR.replace( 'content', {
            filebrowserImageUploadUrl : '{:url("@admin/article/uploadPic")}',//上传图片的后端URL地址
            image_previewText : '&nbsp;',///去掉图片上传预览区域显示的文字
			extraPlugins: 'colorbutton',//使用颜色插件
    });
};
</script>
复制代码

八、自定义工具栏配置

在ckeditor/config.js文件中设置

CKEDITOR.editorConfig = function( config ) {
	//工具栏设置
	config.toolbar = 'MyToolbar';
	config.toolbar_Full = [
		{ name: 'document', items : [ 'Source','-','Save','NewPage','DocProps','Preview','Print','-','Templates' ] },
		{ name: 'clipboard', items : [ 'Cut','Copy','Paste','PasteText','PasteFromWord','-','Undo','Redo' ] },
		{ name: 'editing', items : [ 'Find','Replace','-','SelectAll','-','SpellChecker', 'Scayt' ] },
		{ name: 'forms', items : [ 'Form', 'Checkbox', 'Radio', 'TextField', 'Textarea', 'Select', 'Button', 'ImageButton', 
			'HiddenField' ] },
		'/',
		{ name: 'basicstyles', items : [ 'Bold','Italic','Underline','Strike','Subscript','Superscript','-','RemoveFormat' ] },
		{ name: 'paragraph', items : [ 'NumberedList','BulletedList','-','Outdent','Indent','-','Blockquote','CreateDiv',
		'-','JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock','-','BidiLtr','BidiRtl' ] },
		{ name: 'links', items : [ 'Link','Unlink','Anchor' ] },
		{ name: 'insert', items : [ 'Image','Flash','Table','HorizontalRule','Smiley','SpecialChar','PageBreak','Iframe' ] },
		'/',
		{ name: 'styles', items : [ 'Styles','Format','Font','FontSize' ] },
		{ name: 'colors', items : [ 'TextColor','BGColor' ] },
		{ name: 'tools', items : [ 'Maximize', 'ShowBlocks','-','About' ] }
	]; 
	config.toolbar_Basic = [
		['Bold', 'Italic', '-', 'NumberedList', 'BulletedList', '-', 'Link', 'Unlink','-','About']
	];
	//自定义
	config.toolbar_MyToolbar =[
        //加粗    斜体,    下划线    穿过线    下标字        上标字
        ['Bold','Italic','Underline','Strike','Subscript','Superscript'],
        // 数字列表        实体列表         减小缩进  增大缩进
        ['NumberedList','BulletedList','-','Outdent','Indent'],
        //   左对齐        居中对齐        右对齐        两端对齐
        ['JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'],
        //超链接  取消超链接 锚点
        ['Link','Unlink','Anchor'],
        //图片    flash    表格       水平线        表情     特殊字符      分页符
        ['Image','Flash','Table','HorizontalRule','Smiley','SpecialChar','PageBreak'],
        '/',
        // 样式     格式    字体   字体大小
        ['Styles','Format','Font','FontSize'],
        //文本颜色   背景颜色
        ['TextColor','BGColor'],
        //全屏         显示区块         源码
        ['Maximize', 'ShowBlocks','-','Source']
    ],
	config.format_tags = 'p;h1;h2;h3;h4;h5;h6;pre';
	config.removeButtons = 'Underline,Subscript,Superscript';
	config.removeDialogTabs = 'image:advanced;link:advanced';
	//加载插件
	config.extraPlugins = 'colorbutton,panelbutton,floatpanel'; 
};
