仍然沒有得到其他兩個模具，你永遠不會看到第二模具。 – JTC

如果（$ customer_id => 0）{ $ query = $ query，請使用> =而不是=> –

利用==，而不是=>

=>用於訪問數組的鍵值對，而==用於比較操作。

<?php 
$customer_id = (int)$_REQUEST['customer_id']; 

if ($customer_id == 0){ 
$query = $query . ',' . $_REQUEST['customer_id'] . ""; 
}else{ 
die('cust id: ' . $_REQUEST['customer_id']); 
die ('Please use your browser\'s back button to ensure you have selected a customer'); 
} 

if ($customer_id > 0){ 
$query = $query . ', ' . $_REQUEST['sysuser_id'] . ""; 
} 
else 
{ 
die ('There was a problem with the system user'); 
}

意外的T_ELSE行XXX上。 '，'。 $ _REQUEST ['sysuser_id']。「」; else --------------------------------在這條線上的錯誤 die（'There was a problem with the系統用戶'）; – user2803714

@ user2803714，修改了代碼。 –

=>它應該是>=但你的代碼將看起來像

$customer_id = (int)$_REQUEST['customer_id']; 

     if ($customer_id == 0){ 
        $query = $query . ',' . $_REQUEST['customer_id'] . ""; 
      }else{ 
        die('cust id: ' . $_REQUEST['customer_id']); 
        die ('Please use your browser\'s back button to ensure you have selected a customer'); 
      } 

      if ($customer_id > 0){ 
        $query = $query . ', ' . $_REQUEST['sysuser_id'] . ""; 
      } else { 
        die ('There was a problem with the system user'); 
      }

，如果你想查詢大於等於不是使用心不是像=>

什麼>=

if ($customer_id >= 0){

和小於等於使用>= 和==是等於等於

檢查這個Comparison Operators ¶
