图像在表单中提交按钮 [英] Image Submit Button within a Form

问题描述

我有一个表单，其形式为提交按钮。当用户点击图像按钮时，图像按钮应扮演提交按钮的角色。

代码示例：

 < form action =page.phpmethod =POST> 
< input type =imagename =btn_opentextboxsrc =image.pngvalue =Submit/> 
< / form> 
  

处理提交：

  if（$ _ POST ['btn_opentextbox']）
 {
 //做某事
} 
   
 
 
注意：它可以在Chrome中使用。
 
 
 
我想要它在Firefox，IE等工作。
 
 
 
有什么建议？  
解决方案
您可以添加一个隐藏字段
 < input type =hiddenname =actionvalue =Submit Form > 
  
在php中，您可以做到这一点
 
 
 <$ （$ _ POST ['action'] ==Submit Form）{
做某事
} 
  
  / pre> 
 
 
希望得到这个帮助。 
I have a form that has Submit button in form of an Image. When user clicks the image button, the image button should play the role of submit button.


Code Sample:
<form action="page.php" method="POST">
   <input type="image" name="btn_opentextbox" src="image.png" value="Submit" />
</form>
Handle Submission:
if($_POST['btn_opentextbox'])
{
    //do something
}
Surprisingly, the above code used to work perfectly fine in Firefox. However, once i updated my Firefox yesterday, it didn't work at all. I click the button, page gets refreshed and nothing happens. The code also doesn't work in IE.

Note: it works in Chrome.

I want it to work in Firefox, IE, etc.

Any suggestions?
解决方案
you can add a hidden field
<input type="hidden" name="action" value="Submit Form">
and in php you can do this
if($_POST['action'] == "Submit Form"){
 do something 
}
hope this help.
