似乎在$insertsteps之前和$u get的两个引用周围缺少了一个引号。另外，请先尝试转义变量，最好在调用数据库之前转义输入。转义将有助于保护您的应用程序免受恶意攻击者的攻击，这些攻击者可能试图向sql语句中添加额外命令。
例子：

$InsertSteps = mysql_real_escape_string($InsertSteps);
$InsertPersonnel = mysql_real_escape_string($InsertPersonnel);
$InsertTime = mysql_real_escape_string($InsertTime);
$InsertFees = mysql_real_escape_string($InsertFees);
$InsertDocuments = mysql_real_escape_string($InsertDocuments);
$InsertComplaints = mysql_real_escape_string($InsertComplaints);
$InsertOfficeName = mysql_real_escape_string($_GET["office_name"]);
$InsertApplicationName = mysql_real_escape_string($_GET["application_name"]);

$sql1 = "INSERT INTO `tbl_charter`(`steps`, `personnel`, `timee`, `fees`, `documents`, `complaints`, `office`, `service`) 
         VALUES('$InsertSteps','$InsertPersonnel','$InsertTime','$InsertFees','$InsertDocuments','$InsertComplaints','$InsertOfficeName','$InsertApplicationName')";

$appname=$_GET["application_name"];
$officename=$_GET["office_name"];
$sql1 = "INSERT INTO `tbl_charter`(`steps`, `personnel`, `timee`, `fees`,`documents`, `complaints`, `office`, `service`) VALUES('$InsertSteps','$InsertPersonnel','$InsertTime','$InsertFees','$InsertDocuments','$InsertComplaints','$officename','$appname')";

请在下面的查询中尝试

$sql1 = "INSERT INTO `tbl_charter`(`steps`, `personnel`, `timee`, `fees`, `documents`, `complaints`, `office`, `service`) VALUES('$InsertSteps','$InsertPersonnel','$InsertTime','$InsertFees','$InsertDocuments','$InsertComplaints','".$_GET['office_name']."','".$_GET['application_name']."')";
