Laravel-admin introduces a third-party WangEditor text editor to upload text and pictures.
First go to WangEditor to download the WangEditor package. I use wangEditor-3.0.16
Put the downloaded package in the laravel framework vendor directory
Then create the
content of WangEditor.php WangEditor.php under damin/create Extensions folder
<?php
namespace App\Admin\Extensions;
use Encore\Admin\Form\Field;
class WangEditor extends Field
{
protected $view ='admin.wang -editor';
protected static $css = [
'/vendor/wangEditor-3.0.16/release/wangEditor.min.css',
];
protected static $js = [
'/vendor/wangEditor-3.0.16/release/wangEditor.min.js',
];
public function render()
{
$name = $this->formatName($this->column);
$this->script = <<<EOTvar E = window.wangEditor
var editor = new E('#{$this->id}');
editor.customConfig.uploadFileName = 'mypic[]';
editor.customConfig.uploadImgHeaders = {
'X-CSRF-TOKEN': $('input[name="_token"]').val()
}
editor.customConfig.zIndex = 0;
editor.customConfig.uploadImgServer = '/index.php/uploadFile';
editor.customConfig.onchange = function (html) {
$('input[name=$name]').val(html);
}
editor.customConfig.uploadImgHooks = {
customInsert: function (insertImg, result, editor) {
if (typeof(result.length) != "undefined") {
for (var i = 0; i <= result.length - 1; i++) {
var j = i;
var url = result[i].newFileName;
insertImg(url);
}
toastr.success(result[j]['info']);
}
switch (result['ResultData']) {
case 6:
toastr.error("Up to 4 pictures can be uploaded");
break;
case 5:
toastr. error("Please select a file");
break;
case 4:
toastr.error("Upload failed");
break;
case 3:
toastr.error(result['info']);
break;
case 2:
toastr.error ("File type is illegal");
break;
case 1:
toastr.error(result['info']);
break;
}
}
}
editor.create();
EOT;
return parent::render();
}
}
Note :
Route::post('/uploadFile', [UploadsController::class, 'uploadImg']);//Upload the picture after the route is built, write the text editor and upload the picture
Create UploadsController under http/controller/, pay attention to case
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class UploadsController extends Controller
{
public function uploadImg(Request $request)
{
$file = $request->file("mypic");
if (!empty($file)) {
foreach ($file as $key => $value) {
$len = $key;
}
if ($len > 25) {
return response()->json(['ResultData' => 6, 'info' => '最多可以上传25张图片']);
}
$m = 0;
$k = 0;
for ($i = 0; $i <= $len; $i++) {
// $n 表示第几张图片
$n = $i + 1;
if ($file[$i]->isValid()) {
if (in_array(strtolower($file[$i]->extension()), ['jpeg', 'jpg', 'gif', 'gpeg', 'png'])) {
$picname = $file[$i]->getClientOriginalName();//获取上传原文件名
$ext = $file[$i]->getClientOriginalExtension();//获取上传文件的后缀名
// 重命名
$number = mt_rand(1000000000,9999999999);
$filename = time() .$number . "." . $ext;
if ($file[$i]->move("uploads/images", $filename)) {
$newFileName = '/' . "uploads/images" . '/' . $filename;
$m = $m + 1;
// return response()->json(['ResultData' => 0, 'info' => '上传成功', 'newFileName' => $newFileName ]);
} else {
$k = $k + 1;
// return response()->json(['ResultData' => 4, 'info' => '上传失败']);
}
$msg = $m . "张图片上传成功 " . $k . "张图片上传失败<br>";
$return[] = ['ResultData' => 0, 'info' => $msg, 'newFileName' => $newFileName];
} else {
return response()->json(['ResultData' => 3, 'info' => '第' . $n . '张图片后缀名不合法!<br/>' . '只支持jpeg/jpg/png/gif格式']);
}
} else {
return response()->json(['ResultData' => 1, 'info' => '第' . $n . '张图片超过最大限制!<br/>' . '图片最大支持2M']);
}
}
} else {
return response()->json(['ResultData' => 5, 'info' => '请选择文件']);
}
return $return;
}}
