效果图: 密保卡入库
复制代码 代码如下:
$this->load->model('admin/m_mibao'); $data = array(); //生成随机横坐标 $rand_str = $this->_rand_str(10); $arr = array(); for($k=0;$k<strlen($rand_str);$k++) { for ($i = 1;$i < 9;$i++) { $rand = $this->_rand_num(3); //赋给所有code的容器 $arr[$rand_str{$k} . $i] = $rand; } } $data['code'] = serialize($arr); //序列化后将信息入库 $data['letter'] = $rand_str; //避免重复序列号 while (TRUE) { $data['card_num'] = $this->_rand_num(20); //判断序列号是否重复存在 if($this->m_mibao->has_card_num($data['card_num']) == 0) { break; } } $data['add_time'] = TIME; $data['user_id'] = $uid; echo $this->mibao->insert($data);
密保卡图片生成复制代码 代码如下:
//就是算坐标 public function show($user_id) { $this->load->model('admin/m_mibao'); $info = $this->m_mibao->get_by_uid($user_id); if(emptyempty($info)) { $this->msg('该用户无密保卡!','admin-index'); } $codes = unserialize($info['code']); //图片初始值 $bit = 3; //密保卡位数 $height = 332; //图片高度 $width = 626; //图片宽度 $im = imagecreatetruecolor($width,$height); $linecolor = imagecolorallocate($im, 229,229,229); $fontcolor = imagecolorallocate($im, 0, 0, 0); $top_rectangle_color = imagecolorallocate($im,241,254,237); $top_letter_color = imagecolorallocate($im,54,126,76); $left_rectangle_color = imagecolorallocate($im,243,247,255); $left_num_color = imagecolorallocate($im,4,68,192); $logo_str_color = imagecolorallocate($im,0,0,0); imagefill($im,0,0,imagecolorallocate($im,255,255,255)); //图片背景色 $font = './public/baomi/fonts/simsun.ttc'; //字体 $font_en = './public/baomi/fonts/CONSOLA.TTF'; //英文字体 $font2 = './public/baomi/fonts/simhei.ttf'; //密保卡上方黑体 $dst = imagecreatefromjpeg("./public/baomi/120.jpg"); imagecopymerge($im,$dst,120,15,0,0,193,55,100); imageline($im,10,72,$width-10,72,$linecolor); $ltext = "电子密保卡"; if(!imagettftext($im,10,0,340,47,$logo_str_color,$font2,$ltext)) { exit('error'); } //写入卡号 $b = '1000' . $info['card_num']; for($i=0;$i<7;$i++){ $p.= substr($b,3*$i,4). ' '; } $x = 40; $y = 95; //序列号位置 imagettftext($im,10,0,$x,$y,$color,$font,'序列号'); imagettftext($im,11,0,$x+50,$y,$color,$font_en,$p); //颜色框 imagefilledrectangle($im,10,106,$width-10,128,$top_rectangle_color); imagefilledrectangle($im,10,129,65,$height-10,$left_rectangle_color); //写入最上排英文字母及竖线 for($i=1;$i<=10;$i++){ $x = $i*55+35; $y = 123; $float_size = 11; //字母位置参数 imagettftext($im,$float_size,0,$x,$y,$top_letter_color,$font_en,$info['letter']{$i-1});//写入最上排英文字母 } for($i=0;$i<=9;$i++){ $linex = $i*55+65; $liney = 105; $liney2 = $height-10; //竖线位置参数 imageline($im,$linex,$liney,$linex,$liney2,$linecolor);//划入竖线 } //写入竖排数字及填入矩阵数据 划横线 for($j=0;$j<8;$j++){ $jj=$j+1; $x=35; $y=($jj*24)+123; //左排数字及横线位置参数 imagettftext($im, $float_size, 0, $x, $y, $left_num_color, $font_en, $jj);//写入左排数字 for($i=1;$i<=10;$i++){ $float_size2=11; $x = $i*55+27; $sy=$y; //填入矩阵数据位置参数 $s = $info['letter']{$i-1}; $s .= $j + 1; imagettftext($im,$float_size2,0,$x,$sy,$fontcolor,$font_en,$codes[$s]);//写入矩阵数据 } } for($j=0;$j<10;$j++){ $line_x=10; $line_x2=$width-10;$y=$j*24+105; //横线位置参数 y坐标数据同上 imageline($im,$line_x,$y,$line_x2,$y,$linecolor);//划入横线 } //外框边线 imageline($im,10,10,$width-10,10,$linecolor);//横线 //imageline($im,10,$height-10,$width-10,$height-10,$linecolor); imageline($im,10,10,10,$height-10,$linecolor);//竖线 imageline($im,$width-10,10,$width-10,$height-10,$linecolor); //生成图片 ob_clean(); header("Content-type: image/jpeg"); imagejpeg($im,null,100); imagedestroy($im); }
密保卡验证复制代码 代码如下:
public function test1($uid) { $this->load->model('admin/m_users'); $user = $this->m_users->sel($uid); //post提交过来验证 if($this->is_post()) { $codes = $this->m_mibao->get_codes_by_uid($uid); $codes = unserialize($codes); $is_true = true; foreach($_SESSION['mibao']['keys'] as $key) { if($codes[$key] != $_POST['values'][$key]) { $is_true = false; } } if($is_true) { die('正确'); } else { die('错误'); } } else { //渲染视图 $info = $this->m_mibao->get_by_uid($uid); $data = array(); $data['keys'] = $this->m_mibao->get_rand_keys($info['letter']); $_SESSION['mibao']['keys'] = $data['keys']; $data['uid'] = $uid; $this->load->view('test1',$data); }
