在html中输出的PHP
问题描述：
我正在尝试在同一页面的文本框中发布php的结果，但不知道如何做。代码如下在html中输出的PHP
<form action = "<?php $_PHP_SELF ?>" method = "GET" >
Input1: <input type = "text" name = "input1" />
Input2: <input type = "text" name = "input2" />
Result: <input type = "text" name = "result" />
<input type = "submit" />
</form>
完整代码：
<?php
$input1 = $_GET["input1"];
$input2 = $_GET["input2"];
$result = $input1 + $input2;
echo "$result";
?>
<html>
<body>
<form action = "<?php $_PHP_SELF ?>" method = "GET" >
Input1: <input type = "text" name = "input1" />
Input2: <input type = "text" name = "input2" />
Result: <input type = "text" name = "result" />
<input type = "submit" />
</form>
</body>
</html>
我想表明的结果的文本框$结果。 谢谢。

您可以通过设置value
<?php
$input1 = $_GET["input1"];
$input2 = $_GET["input2"];
$result = $input1 + $input2;
echo "$result";
?>
<html>
<body>
<form action = "<?php $_PHP_SELF ?>" method = "GET" >
Input1: <input type = "text" name = "input1" value="<?=$input1?>" />
Input2: <input type = "text" name = "input2" value="<?=$input2?>"/>
Result: <input type = "text" name = "result" value="<?=$result?>"/>
<input type = "submit" />
</form>
</body>
</html>

做我假设某种加入这里
<form action = "<?php $_PHP_SELF ?>" method = "POST" >
Input1: <input type = "text" value="<?php echo $_POST['input1']; ?>" name = "input1" />
Input2: <input type = "text" value="<?php echo $_POST['input2']; ?>" name = "input2" />
Result: <input type = "text" value="<?php echo ($_POST['input1']+ $_POST['input2']); ?>" name = "result" />
<input type = "submit" />
</form>
的哪里是'$ result'设置？ – mulquin
