有条件地设置表单提交动作 [英] Conditionally set form submit action

问题描述

 < form action =<？php if（isset（$ redirect）&& $; redirect ==f）{echo＃;} 
 else {？> add_new_item2.php？user_id =<？php echo $ _GET ['user_id'];}？>方法= POST > 
 //无需在此处显示此区域
< input type =submitvalue =submitname =submit/> 
< / form> 
 $ b $ //处理器
 
 <？php 
 if（isset（$ _ POST ['submit']））
 {
 $ redirect =f; 
 if（whatever）
 {
 // if条件到达
} 
 else //所有条件满足
 {
 $ redirect =t; 
 
 
 
 
 $ b $ p 
 $ b 
我想要做的事情很简单，如果if条件尚未满足，并且符合要求，动作将为action =add_new_item2.php？user_id = 123，我希望该动作为action =＃。
 
解决方案
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;？>方法= POST > 
  
 
<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";
    }
}
What i want to do is simple in the form action i want the action to be action="#" if the if conditions are not yet met and if they are met the action will be action="add_new_item2.php?user_id=123"
解决方案
try this  
<?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">
