获取url的一部分以使邮件成为主题

如果我没有看错你当前的问题。使用你上一个问题的公认答案，你需要做这样的事情。

$str = "www.test.com/director-sales-120";
$arr=explode("-",$str);
$vacancies = $arr[2];
define( 'PHPFMG_SUBJECT' , "We have $vacancies vacancies" );

查看您提供的功能。它实际上什么都不做，只是设置一些局部变量。因此，如果这个答案不起作用，我们可能需要从该函数中看到更多的代码。

您的解决方案尚未运行。我试图将$空位复制到主题定义字段中，但邮件的主题是空的。

我有两个文件，一个是mailform，另一个是form.lib.

在邮件表单中，我有这样的代码：

 <input type="hidden"style="font-weight:bold" formmethod="POST" name="field_5"  id="field_5" value=" <php  str="http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
 $arr=explode("-",$str); $vacancynumber=end($arr); echo end($arr); ?>" 

这使得该字段确实显示了发送的邮件中的空缺编号。但现在我也必须在这个主题上做这个数字。。。

lib文件显示了这一点（它显示了更多，但我认为这是相关的代码）：

<?php define( 'PHPFMG_SUBJECT' , "" );?>
     <?php
$msg = ob_get_contents() ;
ob_end_clean();
return trim($msg);}
  $GLOBALS['form_mail'] = array();
 $GLOBALS['form_mail']['field_0'] = array( "name" => "field_0", "text" => "Voornaam",  "type" => "senderfirstname", "instruction" => "", "required" => "Required" ) ;
$GLOBALS['form_mail']['field_1'] = array( "name" => "field_1", "text" => "Achternaam",  "type" => "senderlastname", "instruction" => "", "required" => "Required" ) ;
$GLOBALS['form_mail']['field_2'] = array( "name" => "field_2", "text" => "E-mail",  "type" => "sender's email", "instruction" => "", "required" => "Required" ) ;
$GLOBALS['form_mail']['field_3'] = array( "name" => "field_3", "text" => "(Mobiel) Telefoonnummer",  "type" => "text", "instruction" => "", "required" => "Required" ) ;

$GLOBALS['form_mail']['field_5'] = array( "name" => "field_5", "text" => "Vacaturenummer",  "type" => "text", "instruction" => "", "required" => "Required" ) ;
$GLOBALS['form_mail']['field_7'] = array( "name" => "field_7", "text" => "Upload je CV",  "type" => "attachment", "instruction" => "", "required" => "Required" ) ;
$GLOBALS['form_mail']['field_8'] = array( "name" => "field_8", "text" => "Akkoord privacy",  "type" => "checkbox", "instruction" => "", "required" => "" ) ;
$GLOBALS['form_mail']['field_9'] = array( "name" => "field_9", "text" => "Hoe heb je ons gevonden?",  "type" => "checkbox", "instruction" => "", "required" => "Required" ) ;?>
