php - 在第二页转发表单中显示输入名称

Question

我有两种形式。我想在第二个中显示 mobile，mobile 将通过 session 进入。此处显示 session ID，但未显示 mobile。

第一个表格/页面:sign.php

<?php session_start();
<?php $r=session_id();?>
<?php include('include/config.php');?>
<form class="ff" action="signc.php" method="POST">
<a>Enter Your Mobile No.</a>
<input type="text" id="inp" name="mobile" required>
</br></br>
<input type="submit" id="btn" value="continue">
</form>

signc.php

<?php session_start();
<?php $r=session_id();?>
<?php include('include/config.php');?>
$sql = mysqli_query($connection, "INSERT INTO `mobile_message`  SET `mobile` = '$mobile'");

 if($sql){

    $_SESSION['s']= "OTP sent to your mobile.";
        header('Location:sign2.php');

} else{
    $_SESSION['e']=  "Could not able to execute. ";
    header('Location:sign.php');

}

第二个表格/页面:sign2.php

<?php session_start();
<?php $r=session_id();?>
<?php include('include/config.php');?>
<form class="ff" action="sign2c.php" method="POST">
<a class="ase" >Enter Your Mobile No.</a>
<?php
    $cid=$_SESSION['cid'];
    $_q=mysqli_query($connection, "select * from mobile_message where mobile='$cid'");
    $_t=mysqli_fetch_array($_q);
    echo $_t['mobile'];
    echo $r;
    ?>
</br></br>
<a class="ase" >Enter Password</a>
<input type="text" id="inp" name="otp" required>
</br>
<input type="submit" id="btn" value="continue">
</form>

echo $_t['mobile']; 什么都不显示

echo $r; 显示 cgvk2tla6r14h38i2v7dlhkj80

Answer 1

只需在 signc.php 中添加这两行即可

$cid=$_POST['mobile'];

$_SESSION['cid']=$cid;

更正后的 signc.php 会像

<?php session_start();
<?php $r=session_id();?>
<?php include('include/config.php');?>
$sql = mysqli_query($connection, "INSERT INTO `mobile_message`  SET `mobile` = '$mobile'");

 if($sql){

    $cid=$_POST['mobile'];

    $_SESSION['cid']=$cid;

$_SESSION['s']= "OTP sent to your mobile.";
    header('Location:sign2.php');

} else{
$_SESSION['e']=  "Could not able to execute. ";
header('Location:sign.php');

}
