提交后保留表单值

问题描述

我知道还有很多其他的问题是这样的，我在网上找到了1.000个答案，但没有一个与我的代码一起工作:(
那么有人可以帮助我如何在提交后保留电子邮件的价值吗？

 < form name =login-registrationonSubmit =return validateForm（）method =postaction => ; 
< label>电子邮件< / label> 
< input type =emailname =emailinputid =emailinputvalue =/> 
< p id =emptyEmailclass =hidden>需要电子邮件字段< / p> 
 
< label>您的密码< / label> 
< input type =passwordname =pswinputid =pswinputvalue =/> 
< p id =pswMinMaxclass =hidden>密码应该是从4到8个字符< / p> 
< p id =pswLettNumclass =hidden>密码应该是字母和数字mbers。不允许使用特殊字符< / p> 
< label>重复密码< / label> 
< input type =passwordname =pswrepeatinputid =pswrepeatinputvalue =onblur =isValidPswRep（）/> 
< p id =pswRclass =hidden>您的密码不同< / p> 
< input type =checkboxid =policyname =policyvalue =policy/> < label>我同意< / label> 
< p id =checkNclass =hidden>您必须同意我们的< / p> 
 
< input type =submitname =submitvalue =Login/> 
 
< / form> 
  

我尝试添加如下代码：

 < input type =emailname =emailinputid =emailinputvalue =<？php echo htmlspecialchars（$ _ GET ['lastname']）;？> ; /> 
  

但是，该行只显示在字段输入内。

解决方案

1）如果我没有错，在上面的代码中我没有看到任何带有name =lastname的字段。
$ b 2）使用$ _POST，因为您使用method =post发布表单数据。

I know there are lots others question like this and i found 1.000 answer on the web but none of those work with my code :(So can someone help me with how to keep email value after submit?

        <form name="login-registration" onSubmit="return validateForm()" method="post" action="" >
            <label>Email</label>
            <input type="email" name="emailinput" id="emailinput" value ="" />
            <p id="emptyEmail" class="hidden">Email field is required</p>
            <p id="invalidEmail" class="hidden">Email you insert is invalid!</p>
            <label>Your password</label>
            <input type="password" name="pswinput" id="pswinput" value=""/>
            <p id="pswMinMax" class="hidden">Password should be from 4 to 8 caracters</p>
            <p id="pswLettNum" class="hidden">Password should be letters and numbers. No special caracters are allow</p>
            <label>Repeat password</label>
            <input type="password" name="pswrepeatinput" id="pswrepeatinput" value="" onblur="isValidPswRep()"/>
            <p id="pswR" class="hidden">Your passwords is different</p>
            <input type="checkbox" id="policy" name="policy" value="policy" /> <label>I agree</label>
            <p id="checkN" class="hidden">You must agree to our term</p>

            <input type="submit" name="submit" value="Login" />

        </form>

I try to put some code like:

<input type="email" name="emailinput" id="emailinput" value = "<?php echo htmlspecialchars($_GET['lastname']); ?>" />

But that php line is just displayed inside the field input.

解决方案

1)If i am not wrong,i don't see any field with name="lastname" in your code above.

2)Use $_POST because you are posting your form data with method="post".
