如何在PHP中使用OR运算符？

标签： php mysql forms operators

我有一个代码，我在其中检查变量值并尝试应用OR运算符，但我失败了。我的文件有编辑代码。在我的场景中，我使用4提交按钮喜欢保存，提交，批准和重新提交。现在在编辑文件上我启动一个会话并应用条件，如果有用户然后显示保存并提交按钮，但如果有经理然后显示批准和重新提交按钮。 在经理条件我想要应用另一个if条件，如果以前的状态是Approve，那么只显示重新提交按钮，如果以前的状态是保存或提交，则显示两个批准和重新提交按钮

以下是我的代码

<?php
include ("session1.php");
?>
<?php
    require 'database.php';
    $id = null;
    if ( !empty($_GET['id'])) {
        $id = $_REQUEST['id'];
    }

    if ( null==$id ) {
        header("Location: index.php");
    }

    //------------------------------------------Update-------------------------------- 
    if ( !empty($_POST)) {
$editor1 =mysql_real_escape_string(trim($_POST['editor1']));
$editor2 =mysql_real_escape_string(trim($_POST['editor2']));
$editor3 =mysql_real_escape_string(trim($_POST['editor3']));
$editor4 =mysql_real_escape_string(trim($_POST['editor4']));
$editor5 =mysql_real_escape_string(trim($_POST['editor5']));
$editor6 =mysql_real_escape_string(trim($_POST['editor6']));
$editor7 =mysql_real_escape_string(trim($_POST['editor7']));
$editor8 =mysql_real_escape_string(trim($_POST['editor8']));
$editor9 =mysql_real_escape_string(trim($_POST['editor9']));
$editor10 =mysql_real_escape_string(trim($_POST['editor10']));
if($_POST['submit'] == "Submit"){
$status=$_POST['submit'];}

if($_POST['submit'] == "Save"){
$status=$_POST['submit'];}


if($_POST['submit'] == "Approve"){
$status=$_POST['submit'];}

if($_POST['submit'] == "Re-Submit"){
$status=$_POST['submit'];}

$valid = true;
        if ($valid) {
            $pdo = Database::connect();
            $sql = "UPDATE test1  set editor1 ='$editor1', editor2 ='$editor2', editor3 ='$editor3',
                                        editor4 ='$editor4', editor5 = '$editor5', editor6 ='$editor6',
                                        editor7 ='$editor7', editor8 ='$editor8', editor9 ='$editor9',
                                        editor10 ='$editor10', status='$status'  WHERE id ='$id'";
            $q = $pdo->prepare($sql);
            $q->execute(array($editor1,$editor12,$editor3,$editor4,$editor5,$editor6,$editor7,$editor8,$editor9,
            $editor10,$status,$id));
            Database::disconnect();
            header("Location: index.php");
        }
}
    else { 
          }

    $con=mysqli_connect("localhost","root","","pacra1");

         $id2 = $_GET['id'];
        $sql = "SELECT * FROM test1 where id='$id2'";

            $result=mysqli_query($con,$sql);

            $row= (mysqli_fetch_array($result,MYSQLI_ASSOC));

$editor1 =($row['editor1']);
$editor2 =($row['editor2']);
$editor3 =($row['editor3']);
$editor4 =($row['editor4']);
$editor5 =($row['editor5']);
$editor6 =($row['editor6']);
$editor7 =($row['editor7']);
$editor8 =($row['editor8']);
$editor9 =($row['editor9']);
$editor10 =($row['editor10']);
$status =($row['status']);

这是我面临问题的代码

<?php 

if($_SESSION['UserName']=='User')
{
?>
    <input type="submit" name="submit" value="Save">
    <input type="submit" name="submit" value="Submit">
<?php   

    }
    if($_SESSION['UserName']=='Manager')
{
    $_POST['submit']="";

if($_POST['submit'] == "Save" || "Submit")
    {
?>
    <input type="submit" name="submit" value="Approve">
    <input type="submit" name="submit" value="Re-Submit">

<?php   
    }
    }
    else
    {
?>
<input type="submit" name="submit" value="Re-Submit">
<?php
    }
    ?>

您在此处将$_POST['submit']更改为空白。请使用以下代码。

  

删除此行$_POST['submit']="";

     

并将以下内容更改为

<?php
if($_SESSION['UserName']=='Manager')
{

    if($status == 'Approve')
    {
?>
    <input type="submit" name="submit" value="Re-Submit">


<?php   
    }
    else
    {
?>
    <input type="submit" name="submit" value="Approve">
    <input type="submit" name="submit" value="Re-Submit">
<?php
    }
}
?>

答案 1 :(得分：0)

首先删除

行 
$_POST['submit'] = ""

并更改

if($_POST['submit'] == "Save" || "Submit")

到

if(isset($_POST['submit']) && ($_POST['submit'] == "Save" || $_POST['submit'] == "Submit"))

答案 2 :(得分：0)

您正在检查错误地使用OR条件，并且您还要重置$ _POST ['submit']值。它应该是：

<?php 

if($_SESSION['UserName']=='User')
{
?>
    <input type="submit" name="submit" value="Save">
    <input type="submit" name="submit" value="Submit">
<?php   
}

if(isset($_POST['submit']) && $_SESSION['UserName']=='Manager')
{
    if($_POST['submit'] == "Save" || $_POST['submit'] == "Submit")
    {
?>
        <input type="submit" name="submit" value="Approve">
        <input type="submit" name="submit" value="Re-Submit">
<?php   
    }
}
else
{
?>
    <input type="submit" name="submit" value="Re-Submit">
<?php
}
?>
