Question

在我的index.php文件中，我有两组代码。一组代码在很大程度上依赖于php和函数，而另一组代码仅依赖于html。我试图获取提交按钮以获取代码转到文件register.php，但只有html代码进入文件register.php，而php函数代码只是位于同一页面上单击注册按钮。请帮忙。感谢。

在PHP文件中名为functions.php我有3个函数：

<?php

//****************************************************************

function echoForm($action){

echo "<method = 'post' action = '$action'>";

}

//****************************************************************

function echoField($type,$name,$maxlength,$text){

if($type == 'text'){
echo "$text</br><input type = 'text' name='$name' size = '15' maxlength = '$maxlength'/></br>";
}

else if($type == 'pass'){
echo "$text</br><input type = 'password' name = '$name' size = '15' maxlength = '$maxlength'/></br>";
}

else if($type == 'submit'){
echo "<input type = 'submit' name = '$name' value = '$text'/>";
}

}

//****************************************************************

function echoText($text){

echo "$text</br>";

}

?>

在名为index.php的PHP文件中我有我的主要代码：

<?php

include('functions.php');

echoForm('register.php');
echoField('text','username','20','Username');
echoField('pass','password','20','Password');
echoField('text','email','50','Email');
echoField('submit','submit','null','Register');
echoText('</form></br>');

?>

<html>
<body>

<form name = "form" method = "post" action = "register.php">

<input type = "text" name="username" size = "15" maxlength = "20" value=""/> 
<input type = "password" name = "password" size = "15" maxlength = "20" value=""/> 
<input type = "text" name = "email" size = "15" maxlength = "50" value=""/>
<input type = "submit" name = "submit" value = "Register"/>

</form>

</body>
</html>

Answer 1

function echoForm($action){

echo "<method = 'post' action = '$action'>";

}

改变它

function echoForm($action){

echo "<form method = 'post' action = '$action'>";

}

Answer 2

在您的第一个PHP函数echoForm中，您正在尝试打开HTML表单元素，但是您执行此操作的代码缺少form标记。这就是你所拥有的：

function echoForm($action){

   echo "<method = 'post' action = '$action'>";

}

浏览器会将其解释为<method>标记，但它并不理解。为了让它看作一个表单，你的函数必须重新定义如下：

function echoForm($action){

   echo "<form method = 'post' action = '$action'>"; //notice I put `form` before the `method` attribute

   }

提交按钮不在PHP
