emlog网站非插件添加海报方法

emlog网站非插件添加海报方法第5张插图

首先说说下面这两个文件
phpqrcode.phpqrcode.php这两个文件必须要用到具体什么用处你不需要知道
下方有集成包大家想加到其他主题的可以下载看研究

步骤1

在你的模板创建个php文件例如我的haibao.php 创建好后你想放在那放在那要记住路劲需要用到

<div class="dialog_overlay"></div>
<div class="bigger-share">
    <div class="row-share">
        <div class="img-share">
            <img src="<?php echo poster_share($logid, Url::log($logid), img_url($thumbs,$logid,$log_content), $log_title, $date, $blogname, $bloginfo);?>" alt="<?php echo $log_title; ?>">
        <div class="action-haibao">
          <a href="<?php echo poster_share($logid, Url::log($logid), img_url($thumbs,$logid,$log_content), $log_title, $date, $blogname, $bloginfo);?>" download="<?php echo $log_title; ?>"><i class="fa fa-share-alt"></i></a>
          </div>
          </div>
           <div class="share-item">
            <h3>分享文本海报</h3>
            <div class="button">
                <a href="javascript:;" onclick="shareToWeibo('<?php echo Url::log($logid);?>','<?php echo $log_title;?>','<?php echo Url::log($logid);?>','')" title="分享到微博" class="btn btn-danger"><i class="fa fa-weibo"></i> 新浪微博</a>
            </div>
            <div class="button">
                    <a  href="javascript:;" onclick="shareToQzone('<?php echo Url::log($logid);?>','<?php echo $log_title;?>','<?php echo Url::log($logid);?>')" title="分享到QQ好友" class="btn btn-info"> <i class="fa fa-qq"></i> QQ好友</a>
            </div>
            <div class="button">      
                <a  href="javascript:;" onclick="shareToQzone('<?php echo Url::log($logid);?>','<?php echo $log_title;?>','<?php echo Url::log($logid);?>')" title="分享到QQ空间" class="btn btn-warning"> <i class="fa fa-qzone"></i> QQ空间</a>
            </div>
            <div class="button">
                <a href="<?php echo poster_share($logid, Url::log($logid), img_url($thumbs,$logid,$log_content), $log_title, $date, $blogname, $bloginfo);?>" download="<?php echo $log_title; ?>" class="btn btn-primary">
                    <i class="fa fa-cloud-download"></i> 下载海报</a>
            </div>        </div>
        <span class="share-close">
            <i class="fa fa-close"></i>
        </span>
        <div class="text-weixin">
                    <p>长按图片转发给朋友</p>
          </div>
    </div>
</div>

创建好后开始第二步骤

步骤2

打开你的文章页一般都是echo_log.php引入即可
引入代码：

<?php include View::getView('inc/haibao');?>

打开echo_log.php放入加载点

<a class="share-haibao"><i class="fa fa-share-alt"></i> 生成海报</a>

打开heeder.php载入

require_once View::getView('functions');

打开footer.php放在任意地方即可

<?php include View::getView('inc/haibao');?>

放入js fee模板无需放入请忽略这步

$('.share-haibao').click(function() {
            $('.bigger-share').addClass('haibao-on');
            $('.dialog_overlay').show();
            $('.dialog_overlay').click(function() {
            $('.bigger-share').removeClass('haibao-on');
            $('.dialog_overlay').hide();
            });

            });
    $('.share-close').click(function() {
            $('.bigger-share').removeClass('haibao-on');
            $('.dialog_overlay').hide();
            });

步骤3

新建一个functions.php放到模板目录里

<?php 
/**
 * 局部函数库
 */
if(!defined('EMLOG_ROOT')) {exit('error!');}

//获取图片
function img_url($thumburl,$gid,$content,$open=false){
    if($thumburl){
        return $thumburl;
    }elseif(img_zw($content)){
        return img_zw($content);
    }elseif(img_fj($gid) && $open){
        return img_fj($gid);
    }else{
        return TEMPLATE_URL.'images/post.jpg';
    }
}

//抓取远程连接内容
function myCurl($url, $ip = '114.114.114.114'){
    $ch = curl_init();     // Curl 初始化  
    $timeout = 30;     // 超时时间：30s  
    $ua='Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36';    // 伪造抓取 UA  
    curl_setopt($ch, CURLOPT_URL, $url);              // 设置 Curl 目标  
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);      // Curl 请求有返回的值  
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);     // 设置抓取超时时间  
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);        // 跟踪重定向  
    curl_setopt($ch, CURLOPT_ENCODING, "");    // 设置编码  
    curl_setopt($ch, CURLOPT_REFERER, $url);   // 伪造来源网址  
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:'.$ip, 'CLIENT-IP:'.$ip));  //伪造IP  
    curl_setopt($ch, CURLOPT_USERAGENT, $ua);   // 伪造ua   
    curl_setopt($ch, CURLOPT_ENCODING, 'gzip'); // 取消gzip压缩  
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // https请求 不验证证书和hosts  
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);  
    $content = curl_exec($ch);   
    curl_close($ch);    // 结束 Curl  
    return $content;    // 函数返回内容  
}
//海报图生成
function createSharePng($gData,$fileName){
    //创建画布
    $width = 600;
    $height = 800;
    $im = imagecreatetruecolor($width, $height);
    //填充画布背景色
    $color = imagecolorallocate($im, 255, 255, 255);

    $color_200 = imagecolorallocate($im, 200, 200, 200);

    //图片
    $source_path = myCurl($gData["pic"]);
    $head_img = imagecreatefromstring($source_path);
    $target_height = 480;
    $target_width = 600;
