php-使用wangeditor实现数据库数据插入编辑器中

一、数据库查询

从数据库中查询需要展示的数据项**$_POST['neirong'] = $row['neirong'];**

php 复制代码
<?php
if (isset($_GET['Msgid'])) {
    //查询页面数据    
    $sel_sql = "SELECT * from message_board where id = '" . $_GET['Msgid'] . "'";
    $sel_result = DB_query($sel_sql, $db);
    if ($row = DB_fetch_array($sel_result)) {
        $_POST['title'] = $row['title'];
        $_POST['msg_type'] = $row['msg_type'];
        $_POST['enable_flag'] = $row['enable_flag'];
        $_POST['neirong'] = $row['neirong'];
        $_POST['UserID'] = $row['created_by'];
    } else {
        prnMsg(_('找不到相应数据!'), 'error');
    }
}
?>

二、js中取出变量,并对数据进行处理

javascript 复制代码
var dataFromDatabase = '<?php echo htmlspecialchars_decode($_POST['neirong']); ?>';

**htmlspecialchars_decode()**是PHP中的一个函数,用于将字符串中的HTML实体转换回它们对应的字符。在HTML中,有些字符在文本中表示特殊意义,因此需要将其转换为对应的实体表示。例如,<表示小于号(<),>表示大于号(>),&表示&符号等。

例如:我现在的数据库中存的数据是**&lt;h1&gt;标题1&lt;/h1&gt;&lt;p&gt;正文1&lt;/p&gt;** ,name这个函数就会转换为**<h1>标题1</h1><p>正文1</p>**

三、 在编辑器进行显示

通过html: dataFromDatabase,进行设置

javascript 复制代码
//创建编辑器
const editor = createEditor({
    selector: '#editor-container',
    html: dataFromDatabase,
    config: editorConfig,
    mode: 'default', // or 'simple'
})

页面效果

页面完整代码

php 复制代码
<?php
ob_start();
include('includes/session.inc');
$Title = _('修改公告信息');
include('includes/header.inc');
//设置默认值
//获取url的参数
if (isset($_GET['Msgid'])) {
    //查询页面数据    
    $sel_sql = "SELECT * from message_board where id = '" . $_GET['Msgid'] . "'";
    $sel_result = DB_query($sel_sql, $db);
    if ($row = DB_fetch_array($sel_result)) {
        $_POST['title'] = $row['title'];
        $_POST['msg_type'] = $row['msg_type'];
        $_POST['enable_flag'] = $row['enable_flag'];
        $_POST['neirong'] = $row['neirong'];
        $_POST['created_by'] = $row['created_by'];
    } else {
        prnMsg(_('找不到相应数据!'), 'error');
    }
}
?>
<?php
echo '<p class="page_title_text">
		<img src="' . $RootPath . '/css/' . $Theme . '/images/customer.png" title="' . _('联络单建立') .
    '" alt="" />' . ' ' . _('公告修改') . '
	</p>';
if (isset($_POST['UpdateMsg'])) {
    $InputError = 0;
    $i = 1;
    if (mb_strlen($_POST['title']) == 0) {
        $InputError = 1;
        prnMsg(_('标题不能为空!'), 'error');
        $Errors[$i] = 'title';
        $i++;
    } elseif ($_POST['neirong'] == '&lt;p&gt;&lt;br&gt;&lt;/p&gt;') {
        $InputError = 1;
        prnMsg(_('内容不能为空!'), 'error');
        $Errors[$i] = 'neirong';
        $i++;
    } elseif ($_POST['msg_type'] == '&lt;p&gt;&lt;br&gt;&lt;/p&gt;') {
        $InputError = 1;
        prnMsg(_('公告类型不能为空!'), 'error');
        $Errors[$i] = 'msg_type';
        $i++;
    }
    if ($InputError != 1) {
        $SQL_ClientSince = FormatDateForSQL($_POST['ClientSince']);
        if (isset($_POST['UpdateMsg'])) { //it is a new  Customer
            $update_sql = "
                update message_board
                    set title='" . $_POST['title'] . "' ,
                    msg_type='" . $_POST['msg_type'] . "' , 
                    neirong='" . strval($_POST['neirong']) . "' , 
                    enable_flag ='" . $_POST['enable_flag'] . "' , 
                    last_updated_by = '" . $_SESSION['UserID'] . "',
                    last_update_date = '" . time() . "'
                where id='" . $_POST['Msgid'] . "'
            ";
            $ErrMsg = _('This customer could not be added because');
            $update_result = DB_query($update_sql, $db, $ErrMsg);
            prnMsg(_('修改公告成功' . $OrderNum), 'success');
            echo '<br />';
        }
    } else {
        prnMsg(_('修改公告失败!'), 'error');
    }
}
