Question

bookincome.php接受几个输入，bi.php根据bookincome.php的值计算总净收入，并显示一个表格，其中包含用户的所有给定值和计算的总账面收入（ $ tnibeforetax）价值。现在我在report1.php中有一个表，我想在其中显示计算的$ tnibeforetax值，我无法在report1.php中显示该表中的值。请帮忙

bookincome.php的代码：

＆＃13;

<?php
// start session
session_start();
?>
  <!DOCTYPE html>
  <html>

  <head>
    <title> Book Income </title>
  </head>

  <body>
    <center>
      <h2>BOOK INCOME AS PER TRIAL BALANCE ENTRY </h3>
    </center>
    <form name='form' action="bi.php" method='post' autocomplete='off' target="_blank" [....]>
      <table cellspacing="10">
        <tr>
          <br>
          <td align="left">Book Income as per Trial Balance: </td>
          <td><input type="number" name="bi" value="<?php if(isset($_POST['bi'])) ?>"></td>
        </tr>
        <tr>
          <br>
          <td align="left">Late Adjustment 1: </td>
          <td><input type="number" name="la1" value="<?php if(isset($_POST['la1'])) ?>"></td>
        </tr>
        <tr>
          <br>
          <td align="left">Late Adjustment 2: </td>
          <td><input type="number" name="la2" value="<?php if(isset($_POST['la2'])) ?>"><br> </td>
        </tr>
        <tr>
          <br>
          <td align="left">Late Adjustment 3: </td>
          <td><input type="number" name="la3" value="<?php if(isset($_POST['la3'])) ?>"><br> </td>
        </tr>
        <tr>
          <br>
          <td align="left">Audit Adjustment 1: </td>
          <td><input type="number" name="aa1" value="<?php if(isset($_POST['aa1'])) ?>"><br> </td>
        </tr>
        <tr>
          <br>
          <td align="left">Audit Adjustment 2: </td>
          <td><input type="number" name="aa2" value="<?php if(isset($_POST['aa2'])) ?>"><br> </td>
        </tr>
        <tr>
          <br>
          <td align="left">Audit Adjustment 3: </td>
          <td><input type="number" name="aa3" value="<?php if(isset($_POST['aa4'])) ?>"><br> </td>
        </tr>

      </table>
      <br>
      <center> <button type="submit" value="Submit">Submit</button>
        <button type="reset" value="Reset">Reset</button> </center>
    </form>
  </body>

  </html>

＆＃13;

以下是bi.php的代码：

＆＃13;

<?php
// start session
session_start();

			$bi = $_POST['bi'];
			$la1 = $_POST['la1'];
			$la2 = $_POST['la2'];
			$la3 = $_POST['la3'];
			$aa1 = $_POST['aa1'];
			$aa2 = $_POST['aa2'];
			$aa3 = $_POST['aa3'];
			
			$tnibeforetax= $bi + $la1 + $la2 + $la3 + $aa1 + $aa2 + $aa3;
			
			$_SESSION['tnibeforetax'] = $tnibeforetax;

        <td align="right">
          <?php echo $tnibeforetax ; ?> </td>
      </tr>

＆＃13;

report1.php的代码：

＆＃13;

<?php
// start session
session_start();

$tnibeforetax = $_SESSION['$tnibeforetax'];

?>
<!DOCTYPE html>

	<tr>

Answer 1

您只是checking而不是checking and printing所以在此更改以及

以下的所有内容

<td><input type="number" name="bi" value="<?php $_POST['bi'] ?? '' ?>"></td>

此处$_POST['bi'] ?? ''与php 7中的isset($_POST['bi']) ? $_POST['bi'] : ''相同。

为bi.php

添加相同的检查

$bi = $_POST['bi'] ?? 0;

Answer 2

$tnibeforetax = $_SESSION['$tnibeforetax'];

值内没有$。

Answer 3

它无法正常工作的原因是因为您将会话设置为值tnibeforetax但是使用$tnibeforetax设置，请替换第3个文件中的上述代码，即report1.php 。

 <?php
    // start session
    session_start();

    $tnibeforetax = $_SESSION['tnibeforetax'];

    ?>

Answer 4

您忘记在value属性中添加结果的输出。

<td><input type="number" name="bi" value="<?php $_POST['bi'] ?? '' ?>"></td>到

<td><input type="number" name="bi" value="<?php echo isset($_POST['bi']) ? $_POST['bi'] : '' ?>"></td>

la1，la2等等。

在php.ini文件中使用short_open_tag=On，它可以只是<?= isset($_POST['bi']) ? $_POST['bi'] : '' ?>。在PHP 7中，它可以只是<?= $_POST['bi'] ?? '' ?>。

report1.php中的

$tnibeforetax = $_SESSION['$tnibeforetax'];必须是

$tnibeforetax = $_SESSION['tnibeforetax'];

请为变量使用更易理解的名称。变量的名称必须尽可能清楚地匹配存储在其中的数据。例如，而不是bi使用bookIncome。

Answer 5

please remove the $ sign from ['$tnibeforetax'] that is written as $tnibeforetax = $_SESSION['$tnibeforetax'] in report1 code section

将变量从一个php文件发送到另一个php文件并在第三个文件中显示变量值
