ckeditor php上傳

CKEditor是一款廣為流傳的富文本編輯器，提供了豐富的編輯選項和美觀的界面設計，被廣泛應用于網(wǎng)站開發(fā)和內(nèi)容管理系統(tǒng)中。隨著互聯(lián)網(wǎng)技術(shù)的不斷發(fā)展，許多網(wǎng)站需要支持圖片上傳功能，CKEditor也應運而生。接下來，我們將重點介紹如何在PHP中使用CKEditor上傳圖片。
首先，我們需要準備一個基礎的CKEditor編輯器代碼，這里我們直接使用CKEditor官方提供的代碼，如下所示：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>CKEditor在上述代碼中，我們可以看到使用了CDN引入了CKEditor的JavaScript文件，還有一個標簽，CKEDITOR.replace()方法將它轉(zhuǎn)換為一個具有豐富編輯功能的富文本編輯器。</p><p>接下來，我們需要為CKEditor添加上傳圖片功能，我們可以按照以下步驟進行：</p><p><strong>1. 為上傳圖片創(chuàng)建HTML標記</strong></p><p>在<textarea>標記后添加如下代碼：</p><pre><form method="post" enctype="multipart/form-data" id="uploadForm">
<input type="file" name="upload" onchange="uploadImage()" id="uploadInput">
</form></pre><p>需要注意的是，表單的enctype屬性要設置為“multipart/form-data”，以支持文件上傳。我們還為<input type="file">標記添加了id屬性，并指定了onchange事件，將在選擇上傳文件時調(diào)用uploadImage()函數(shù)。</p><p><strong>2. 創(chuàng)建JavaScript函數(shù)uploadImage()</strong></p><p>上傳圖片的核心代碼實現(xiàn)就在這里。我們需要創(chuàng)建一個JavaScript函數(shù)uploadImage()，實現(xiàn)文件上傳和CKEditor圖片插入的功能。</p><pre><script type="text/javascript">
function uploadImage() {
var file_data = $('#uploadInput').prop('files')[0];
var form_data = new FormData();
form_data.append('file', file_data);
$.ajax({
type: 'POST',
url: 'upload.php',
processData: false,
contentType: false,
data: form_data,
success: function(response) {
var url = response.trim();
var editor = CKEDITOR.instances.editor;
editor.insertHtml('<img src="' + url + '">');
}
});
}
</script></pre><p>在上述代碼中，我們用jQuery選擇了<input type="file">標記，并按照FormData的格式將文件數(shù)據(jù)保存到了form_data變量中。然后，我們使用jQuery的ajax方法發(fā)送POST請求到“upload.php”頁面，傳遞form_data變量，實現(xiàn)圖片文件的上傳。</p><p>當服務器返回上傳成功后，我們使用CKEditor的insertHtml()方法將插入一個圖片標記到編輯器中。需要注意的是，我們拼接圖片標記時使用了上傳成功后返回的url地址。</p><p><strong>3. 編寫服務器端上傳腳本</strong></p><p>最后，我們需要編寫一個PHP腳本處理文件上傳。我們將文件保存在服務器上，并返回其URL地址，供前端JavaScript調(diào)用。簡單的PHP腳本如下：</p><pre><?php
$file = $_FILES['file'];
$filename = $file['name'];
$ext = pathinfo($filename, PATHINFO_EXTENSION);
$tmp = $file['tmp_name'];
$dir = 'uploads/';
$name = uniqid() . '.' . $ext;
move_uploaded_file($tmp, $dir . $name);
$url = $dir . $name;
echo $url;
?></pre><p>上述代碼共做了幾件事：獲取上傳文件的各種屬性，并按照一定規(guī)則對文件進行重命名和存儲。最后，將文件的URL地址返回給uploadImage()函數(shù)。在此部分的代碼編寫中，需要注意文件上傳后的存儲路徑和文件名的設置。</p><p>通過以上幾步，我們就成功的為CKEditor添加了圖片上傳功能，成為一個真正強大的富文本編輯器。</p></div><div   id="nphl7db"   class="share"></div><div   id="dzf555p"   class="Prev_Next"><div   id="7f5jdhh"   class="box">上一篇<a href="http://www.lofty888.cn/post/1469135.html">macos 10.11.6發(fā)布</a></div><div   id="tfjbhjf"   class="box">下一篇<a href="http://www.lofty888.cn/post/1382822.html">ckeditor 圖片 php</a></div></div></div><div   id="p5bdj55"   class="related related-list"><h5>相關(guān)文章</h5><ul><li><a href="http://www.lofty888.cn/post/1625053.html">php html特殊字符代碼轉(zhuǎn)意</a><span>12-18</span></li><li><a href="http://www.lofty888.cn/post/1625051.html">php html片段所有標簽的屬性值</a><span>12-18</span></li><li><a href="http://www.lofty888.cn/post/1625049.html">php html文本編輯器</a><span>12-18</span></li><li><a href="http://www.lofty888.cn/post/1625047.html">php html文字生成圖片不顯示</a><span>12-18</span></li><li><a href="http://www.lofty888.cn/post/1625045.html">php html撲克牌比大小</a><span>12-18</span></li><li><a href="http://www.lofty888.cn/post/1625042.html">php html帶參數(shù)的跳轉(zhuǎn)頁面</a><span>12-18</span></li><li><a href="http://www.lofty888.cn/post/1625040.html">php html導出word默認橫屏</a><span>12-18</span></li><li><a href="http://www.lofty888.cn/post/1625038.html">php html實現(xiàn)二級聯(lián)動菜單</a><span>12-18</span></li><li><a href="http://www.lofty888.cn/post/1625037.html">php html實現(xiàn)二級聯(lián)動</a><span>12-18</span></li><li><a href="http://www.lofty888.cn/post/1625035.html">php html字符轉(zhuǎn)換為字符串</a><span>12-18</span></li><li><a href="http://www.lofty888.cn/post/1625033.html">php html如何放在一起</a><span>12-18</span></li><li><a href="http://www.lofty888.cn/post/1625031.html">php html同一頁面跳轉(zhuǎn)</a><span>12-18</span></li><li><a href="http://www.lofty888.cn/post/1625029.html">php html同一頁面</a><span>12-18</span></li><li><a href="http://www.lofty888.cn/post/1625027.html">php html可視化編輯器</a><span>12-17</span></li><li><a href="http://www.lofty888.cn/post/1625025.html">php html可以顯示不出來的</a><span>12-17</span></li><li><a href="http://www.lofty888.cn/post/1402095.html">navicat和php</a><span>07-24</span></li><li><a href="http://www.lofty888.cn/post/1490008.html">php laravel restful</a><span>08-08</span></li><li><a href="http://www.lofty888.cn/post/1491388.html">php linajieshujuku</a><span>08-07</span></li><li><a href="http://www.lofty888.cn/post/1419440.html">php crypt</a><span>07-15</span></li><li><a href="http://www.lofty888.cn/post/1567716.html">php redis decr</a><span>09-14</span></li><li><a href="http://www.lofty888.cn/post/1604671.html">php transmitnews</a><span>10-03</span></li><li><a href="http://www.lofty888.cn/post/1409414.html">php -m -n</a><span>07-20</span></li><li><a href="http://www.lofty888.cn/post/1483633.html">php iso</a><span>08-12</span></li><li><a href="http://www.lofty888.cn/post/1493432.html">php manual 2017</a><span>08-06</span></li><li><a href="http://www.lofty888.cn/post/1364534.html">9959php</a><span>07-19</span></li><li><a href="http://www.lofty888.cn/post/1622481.html">php carbon萬年歷代碼</a><span>04-18</span></li><li><a href="http://www.lofty888.cn/post/1428671.html">php getrequest()-</a><span>07-09</span></li><li><a href="http://www.lofty888.cn/post/1491709.html">php limit語法</a><span>08-07</span></li><li><a href="http://www.lofty888.cn/post/1387826.html">Facebook拋棄PHP</a><span>08-01</span></li><li><a href="http://www.lofty888.cn/post/1605165.html">php Trim</a><span>10-04</span></li></ul></div></div></div></div><div   class="pbzfv75"   id="footer"><div   id="t55lffv"   class="copyright"><div   id="vtzf5x5"   class="container"><p>老白網(wǎng)絡 (http://www.lofty888.cn/) 前端 后端 zblog主題.<a href="http://www.lofty888.cn/sitemap/post.html">網(wǎng)站地圖</a><a href="http://www.lofty888.cn/sitemap/post.xml">xml</a></p><span>Powered By Z-BlogPHP</span></div></div></div><div   id="7rj5lh5"   class="bottom_tools"><a id="scrollUp" href="javascript:;" title="返回頂部"><i class="fa fa-angle-up"></i></a></div><script type="text/javascript" src="http://cdn.staticfile.org/jquery/2.2.4/jquery.min.js"></script><script src="http://cdn.yzktw.com.cn/zb_users/theme/ydproduct/script/ads.js" type="text/javascript"></script><script src="http://cdn.yzktw.com.cn/zb_users/theme/ydproduct/script/common.min.js" type="text/javascript"></script><script src="http://cdn.staticfile.org/prettify/r298/prettify.min.js" type="text/javascript"></script><script>jQuery(window).load(function(){jQuery("pre").addClass("prettyprint");prettyPrint();});</script><div   class="jvzhnbz"   id="ly_cache" data-id="1382815"></div>
