我在这里使用“Alin Purcaru”代码PHP mail() attachment problems 它适用于单个附件，但不适用于多个附件。 我最大的问题是随机输入文本输入之间的附件字段。
<input name="attach1" type="file" value=""/>
<input name="email" type="text" value=""/>
<input name="attach2" type="file" value=""/>
因此无法让所有事情都发挥作用。 我尝试了下面给出的同样问题的其他解决方案，但那些根本没有用。您能否告诉我如何更改此代码以用于多个附件？
答案 0 :(得分：1)
试试这个：
<input name="attach" type="file" value="" multiple/>

所以要完成我的回复，请按照以下步骤操作：

定义一个帮助程序，以便从 apache 网站获取所有已知mimes类型的最新数组，我们稍后会在您的电子邮件附件中使用它们：
define('APACHE_MIME_TYPES_URL','http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types');
function generateUpToDateMimeArray($url){
$s=array();
foreach(@explode("\n",@file_get_contents($url))as $x)
if(isset($x[0])&&$x[0]!=='#'&&preg_match_all('#([^\s]+)#',$x,$out)&&
isset($out[1])&&($c=count($out[1]))>1)
for($i=1;$i<$c;$i++)
$s[]=' \''.$out[1][$i].'\' => \''.$out[1][0].'\'';
return @sort($s)?'$mime_types = array(<br />'.implode($s,',<br />').'<br />);':false;
}
定义一个帮助程序，避免显示所需的字符代替重音字符
function remove_accents($str, $charset='utf-8')
{
$str = htmlentities($str, ENT_NOQUOTES, $charset);
$str = preg_replace('#\&([A-za-z])(?:acute|cedil|circ|grave|ring|tilde|uml)\;#', '\1', $str);
$str = preg_replace('#\&([A-za-z]{2})(?:lig)\;#', '\1', $str);
$str = preg_replace('#\&[^;]+\;#', '', $str);
return $str;
}
处理数据并发送电子邮件：

// Other servers
