效果图:
密保卡入库
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;$k{
for ($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
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
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);
}
