将变量从一个页面传输到另一个页面[关闭]

Question

I derived the data from database and stored like that in php

<tr>
<td><a href=SMSindex.php?tp_no=$row[tel] >
     <img src=images/phone.png width=30 height=30 >
    </a>
</td>
<td>".$row["name"]."</td> </tr>

when I click the phone.png image, the SMSindex.php want to echo they phone number without show in the URL.(if is just use $_GET[tel] get the answer but same time i can see in the same phone no in url also.)

Answer 1

You can use sessions to achieve this.

You have a syntax error here.

<td>".$row["name"]."</td> </tr>

It shall be fixed by

<td><?php echo $row['name'] ?></td> </tr>

[ Or the way Hanky 웃 Panky suggested ]

You can have it in your session by

<?php
session_start();
$_SESSION['name'] = $row['name']
?>

And retrieve it on another page by

<?php
session_start();
echo $_SESSION['name'];
?>

Update :

If you have this in your url and you want to have your tp_no globally available then you should replace the $row['name'] by $_GET['tp_no']

http://localhost:88/web/SMSindex.php?tp_no={%27tel:[phone]%27}

You should get the tp_no by

$_GET['tp_no']

But I don't know the reason you wrap around {}

Update :

As you don't want to see the url in the page.

Here's a tiny workaround to overcome it.

<?php
session_start();
if (isset($_GET['tp_no'])) 
{
$_SESSION['tp_no'] = $_GET['tp_no'];
unset($_GET['tp_no']);
$url = $_SERVER['SCRIPT_NAME'].http_build_query($_GET);
header("Refresh:0; url=".$url);
}
elseif (isset($_SESSION['tp_no'])) 
{
echo $_SESSION['tp_no'];
session_unset();
session_destroy();
}
else
{
    echo "Direct / Illegal Access not allowed";
}
?>

An Explained Version

<?php
session_start();    #Starting the Session
if (isset($_GET['tp_no']))  #Checking whether we have $_GET value from the url 
{
$_SESSION['tp_no'] = $_GET['tp_no']; # We are assiging the tp_no to session
unset($_GET['tp_no']); #Here we are unsetting the value that we get from url
$url = $_SERVER['SCRIPT_NAME'].http_build_query($_GET); #Here we are removing gettgint the url and removing the tp_no from it 
header("Refresh:0; url=".$url); #Now we are redirecting/refreshing the page with tp_no - As you said you need it :)
}
elseif (isset($_SESSION['tp_no']))  
#Here is the else if condition once we refresh the page we won't have $_GET so the it will come inside this loop
{
echo $_SESSION['tp_no']; #Displaying the value that is from the session
session_unset();     #Unsetting the session value for secure
session_destroy();   #Destroying the entire session value for secure
}
else
{
#The compiler will come to this part if both session or url is not set, So this is illegal area
    echo "Direct / Illegal Access not allowed";  
#There might be some hackers/genius persons who will try to access directly this page, to avoid them we are showing them the above warning message
