cancel button using php
提问by Maerlyn
I have a form,if users clicks cancel with value or w/o value in the textfield it should redirect.
我有一个表单，如果用户在文本字段中单击带有值或不带值的取消，它应该重定向。
Now w/o entering value it is working.If users enters it is getting into db.
现在没有输入值它正在工作。如果用户输入它正在进入数据库。
I tried all js scripts but still not working
我尝试了所有 js 脚本，但仍然无法正常工作

Why redirec? Should cancel work as canceling the actual action and getting back to previous one? I thing that history.back() should be suffcient in js. Or window.close() if the form is opened in new window. But to make this happend you should make cancel a regular button, not a submit.
为什么要重定向？取消是否应该像取消实际操作并返回上一个操作一样工作？我认为 history.back() 在 js 中应该足够了。或者 window.close() 如果表单在新窗口中打开。但是要做到这一点，您应该使取消成为常规按钮，而不是提交。
Something like this:<input type="button" ... value="Cancel" onclick="history.back();" />
像这样的东西：<input type="button" ... value="Cancel" onclick="history.back();" />

Try this and change redirectpage to your redirectpage.
试试这个并将重定向页面更改为您的重定向页面。
<input type="button" value="cancel" onClick="document.location.href='http://www.redirectpage.com';" />
<input type="button" value="cancel" onClick="document.location.href='http://www.redirectpage.com';" />

whenever you have an <input type="submit">think of this as just another field value you can check against in your code. e.g. try this:
每当您<input type="submit">认为这只是另一个字段值时，您可以在代码中进行检查。例如试试这个：
<form action="<?php $_SERVER['PHP_SELF'] ?>" method="GET">
<input type="submit" name="foo" value="submit">
<input type="submit" name="foo" value="cancel">
</form>
<?php
//validation removed..
if ($_GET['foo'] == 'submit')
{
//do snazzy stuff
print('submit pressed')
}
if ($_GET['foo']) == 'cancel')
{
//do snazzy stuff
print('cancel pressed')
}
?>
hope this helps?
希望这可以帮助？

You should emphasize the default (submit) action versus the secondary one (cancel). Make submit a regular submit button, cancel a link to the previous page.
您应该强调默认（提交）操作与次要操作（取消）。使提交常规提交按钮，取消到上一页的链接。
