PHP驱动QR代码生成器

此QR码发生器只允许您为一个内容字段生成。我想补充的方式来产生所有可以使用PHP生成这里的信息：http://zxing.appspot.com/generator/PHP驱动QR代码生成器

我希望用户能够编码MECARD和vCard

这是我到目前为止有：

<div id="generator"> 
    <form target="qrcode-frame" action="gen.php" method="post"> 
     <fieldset> 
     <legend>Size:</legend> 
     <input type="radio" name="size" value="150x150" checked>150x150<br> 
     <input type="radio" name="size" value="200x200">200x200<br> 
     <input type="radio" name="size" value="250x250">250x250<br> 
     <input type="radio" name="size" value="300x300">300x300<br> 
     </fieldset> 
     <fieldset> 
     <legend>Encoding:</legend> 
     <input type="radio" name="encoding" value="UTF-8" checked>UTF-8<br> 
     <input type="radio" name="encoding" value="Shift_JIS">Shift_JIS<br> 
     <input type="radio" name="encoding" value="ISO-8859-1">ISO-8859-1<br> 
     </fieldset> 
     <fieldset> 
     <legend>Content:</legend> 
     <textarea name="content"></textarea> 
     </fieldset>   
     <fieldset> 
     <legend>Error correction:</legend> 
     <select name="correction"> 
      <option value="L" selected>L</option> 
      <option value="M">M</option> 
      <option value="Q">Q</option> 
      <option value="H">H</option> 
     </select> 
     </fieldset>   
     <input type="submit" value="Generate"></input> 
    </form> 
</div> 
<div id="result"> 
    <iframe name="qrcode-frame" frameborder="0" id="qrcode" src="gen.php" height="315px;" width="350px"></iframe> 
</div>

，这在另一个文件：

<?php 
if(isset($_REQUEST['content'])){ 
    //capture from the form 
    $size   = $_REQUEST['size']; 
    $content  = $_REQUEST['content']; 
    $correction = strtoupper($_REQUEST['correction']); 
    $encoding  = $_REQUEST['encoding']; 

    //form google chart api link 
    $rootUrl = "https://chart.googleapis.com/chart?cht=qr&chs=$size&chl=$content&choe=$encoding&chld=$correction"; 

    //print out the image 
    echo '<img src="'.$rootUrl.'">'; 
} 
?>

这个伟大的工程，但非常有限。

感谢

将这项工作？ https://github.com/edent/QR-Generator-PHP –

你好zerkms，我不想雇人，因为我想学习如何做到这一点。只需要指出正确的方向。 – Matt

贝勒，感谢您的有用信息。我会现在检查它。 – Matt

我们有重要的参数

cht=qr         Required -> Specifies a QR code 
chs=<width>x<height>     Required -> Image size 
chl=<data>        Required -> more than 2K bytes (minus the other URL characters), you will have to send your data using POST 
choe=<output_encoding>     Optional -> UTF-8 , Shift_JIS , ISO-8859-1 
chld=<error_correction_level>|<margin> Optional -> 

error_correction_level 
L - [Default] Allows recovery of up to 7% data loss 
M - Allows recovery of up to 15% data loss 
Q - Allows recovery of up to 25% data loss 
H - Allows recovery of up to 30% data loss 

margin - The width of the white border around the data portion of the code.

more details here

所以我们

1-链接

$data = 'http://chart.apis.google.com/chart?'; // url

2-参数

$data .= 'cht=qr&chs=' . $Barcode_size . '&chld=' . $Error_correction . '&choe=' .$Character_encoding . '&chl=' . $Encoding . ':'; // parameters

3-我们的数据

$data .= 'name:' . $Name . ';Company:' . $Company . ';Title:' . $Title . ';Phone_number:' . $Phone_number . ';Email:' . $Email . ';Address:' . $Address . ';Website:' . $Website . ';Memo:' . $Memo . ';;';

结果将是这样的

http://chart.apis.google.com/chart?cht=qr&chs=120x120&chld=L&choe=UTF-8&chl=MECARD:name:MyName;Company:MyCo;Title:ttt;Phone_number:ttt;Email:ttt;Address:ttt;Website:tt;Memo:ttt;;

通知所述数据：

name MyName - >像那样写 - > name：MyName;

数据名称：数据值; //你可以只发送值，而它的名字

，并在该行的末尾，你会发现两个分号

非常感谢所有的信息！ – Matt

如果您希望对此更改使用HTTPS'http://chart.apis.google.com'>>'https://chart.googleapis.com'，其余内容均正常。 –

，你可以在这里找到细节https://developers.google.com/chart/infographics/docs/qr_codes#details

和这里的例子http://www.cognation.net/QR/Google_api.htm

，如果你需要的HTML代码和PHP代码，请写出来与大家需要创建

我会为你创建一个例子。

嗨阿博，那真是太好了，我会喜欢一个例子！当你有时间时，我不急。谢谢！ – Matt

这个例子很好地工作我必须处理错误（空文本）

例如：

必须包括jQuery的。JS HTML：

<html> 

<head> 

<meta content="text/html; charset=UTF-8" http-equiv="content-type"> 
<script src="jquery.js" type="text/javascript"> </script> 

<script language="JavaScript" type="text/javascript" > 

function get_url() 
{ 

$.ajax(
{ 
type: 'POST', 
url: 'gen.php', 
dataType: "html", 
data: {Name: $('#Name').val(), Company: $('#Company').val(),Title: $('#Title').val(), Phone_number: $('#Phone_number').val(),Email: $('#Email').val(), Address: $('#Address').val(),Address_2 : $('#Address_2').val(), Website: $('#Website').val(),Memo: $('#Memo').val(), Encoding: $('#Encoding option:selected').val(), Barcode_size: $('#Barcode_size option:selected').val(), Error_correction: $('#Error_correction option:selected').val(), Character_encoding: $('#Character_encoding option:selected').val()}, 
success: function(msg) { 
$('#myurl').val(msg); 
$('#img').attr('src',msg); 

} }); 

} 



</script> 

<title> 
</title> 


</head>
