Question

I want to pass a variable to next page but i doesn't seem to work as expected. I have done samething on a different page but now it dosen't work.

This is the metod im using to pass the variables (email.php): <div class='alternativ'> <td width="50%" style=" padding:5px;"> <form method='GET' action='excelimport.php'> <input type='hidden' name='pidnew3' value='$pidnew2'> <input type="submit" name="submit"> </form></td> </div>

and in excelimport.php i have this:$pidnew4 = $_POST['pidnew3'];

Im getting 2 error in excelimport.php:

Notice: Undefined index: pidnew3 in D:\home\site\wwwroot\devlopment\excelimport.php on line 77

its reffering to this: $pidnew4 = $_POST['pidnew3'];

Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in D:\home\site\wwwroot\devlopment\excelimport.php on line 102

and this is reffering to this: $recResult = mysql_fetch_array($sql);

I have this php (email.php) page that i want to pass to another.:

<?php 
include_once 'includes/db_connect.php';
include_once 'includes/functions2.php';
include_once 'includes/config.php'; 
error_reporting(-1); ini_set( 'display_errors', 1 );

 //Start av sessions
sec_session_start();
if (login_check($mysqli) == true) {
    $logged = 'Inloggad';
} else {
    $logged = 'utloggad';
}


$uploadedStatus = 0;

if ( isset($_POST["submit"]) ) {
if ( isset($_FILES["file"])) {
//if there was an error uploading the file
if ($_FILES["file"]["error"] > 0) {
echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
}
else {
if (file_exists($_FILES["file"]["name"])) {
unlink($_FILES["file"]["name"]);
}
$storagename = "discussdesk.xlsx";
move_uploaded_file($_FILES["file"]["tmp_name"],  $storagename);
$uploadedStatus = 1;
}
} else {
echo "Ingen fil vald <br />";
}
}

?>

Answer 1

<form method='GET' action='excelimport.php'> 
    <input type='hidden' name='pidnew3' value='$pidnew2'> 
    <input type="submit" name="submit">
</form>

In this form, you mentioned GET method and you are passing variable using GET method in your another page.

You can not get pidnew3 variable to another page because you are using POST method to get pidnew3 variable.

You just need to change the below line from

$pidnew4 = $_POST['pidnew3'];

to

$pidnew4 = $_GET['pidnew3'];

Answer 2

我刚刚意识到可能出现的问题，你没有在这里显示$ pidnew2值

<form method='GET' action='excelimport.php'>
    <input type='hidden' name='pidnew3' value='$pidnew2'>
    <input type="submit" name="submit">
</form>

您应该用

替换该块

<form method='GET' action='excelimport.php'>
    <input type='hidden' name='pidnew3' value='<?php echo $pidnew2; ?>'>
    <input type="submit" name="submit">
</form>

然后你得到变量$ pidnew2的值而不是字符串＆＃39; $ pidnew2＆＃39;

Answer 3

You should change the method in the form by POST, as you are trying to get a variable passed through 'GET'. Or as below you can get the variable using the 'GET' method.

$pidnew4 = $_GET['pidnew3'];

PHP Pass variable to next page not working
