<form action="<?php if(isset($redirect)&& $redirect == "f"){echo "#";}
else{ ?>add_new_item2.php?user_id=<?php echo $_GET['user_id']; }?>" method="post">
//no need to expose this area here
<input type="submit" value="submit" name="submit" />
</form>
//the processor
<?php
if(isset($_POST['submit']))
{
$redirect = "f";
if(whatever)
{
//the if condition comes here
}
else //all if conditions are satisfied
{
$redirect = "t";
}
}
我想做的事情很简单,在表单操作中我希望操作成为action =“#”如果if条件尚未满足,如果满足,则操作将是action =“add_new_item2.php?user_id = 123"

试试这个
<?php
$action = '';
if(isset($redirect) && $redirect == "f") {
$action = "#";
} else {
$action = "add_new_item2.php?user_id=".$_GET['user_id'];
}
?>
<form action="<?php echo $action; ?>" method="post">

你在使用前做出条件意味着......
<?php
$action = '';
if(isset($redirect) && $redirect == "f") {
$action = "#";
} else {
$action = "add_new_item2.php?user_id=".$_GET['user_id'];
}
?>
<form action="<?php echo $action; ?>" method="post">

如果已设置重定向值。使用$_SERVER['PHP_SELF']
对当前页面执行操作。
检查引号$redirect == "f"
。它应该是单引号或正确转义。
<form name="form1" method="post"
action="<?php
if(isset($redirect)&& $redirect == 'f'){echo $_SERVER['PHP_SELF'];}
else{ echo 'add_new_item2.php?user_id='.$_GET['user_id']; }
?>"

尝试在双引号前后加单引号。与此类似:
<input type=label name=\"Description1\" value='". $T_Description. "' style=\"width:650px; margin-left:50px; padding: 5px;\" \>
(value ='“ x ”') 希望这会有所帮助...
