遍历选定的用户并动态填充下拉列表

Question

So this is a part from the administrator page. After several modifications I came to this, which is the best I could get unfortunately:

<?php

$sql = "SELECT name
        FROM users";
$result = mysqli_query($connection, $sql);

$users = array();

while ($row = mysqli_fetch_assoc($result))
{
     $users[] = $row["name"];
}

echo ('</br><form action="" method="POST" style="display:inline!important"></br>
        <select name="deleteUser">
        <option value="' . $users[1] . '">' . $users[1] . '</option>' . 
       '<option value="' . $users[2] . '">' . $users[2] . '</option>' .
       '<option value="' . $users[3] . '">' . $users[3] . '</option>' .
       '<option value="' . $users[4] . '">' . $users[4] . '</option>' .
       '<input class="w3-bar-item w3-button w3-hide-small w3-hover-green"  type="submit" value="Delete" name="delete"></select></form>');
if (isset($_POST["delete"]))
{
     $sql = "DELETE
             FROM users
             WHERE name = '" . $_POST["deleteUser"] . "'";
     mysqli_query($connection, $sql);

}
?>

I tried to write a loop to generate the select options like this:

<?php

$sql = "SELECT name
        FROM users";
$result = mysqli_query($connection, $sql);

$users = array();

while ($row = mysqli_fetch_assoc($result))
{
     $users[] = $row["name"];
}

echo ('</br><form action="" method="POST" style="display:inline!important"></br>
        <select name="deleteUser">');

for ($i = 0; $i < count($users); $i++)
{
    echo('<option value="' . $users[$i] . '">' . $users[$i] . '</option>');
}   

echo('<input class="w3-bar-item w3-button w3-hide-small w3-hover-green"  type="submit" value="Delete"></select></form>');
if (isset($_POST["delete"]))
{
     $sql = "DELETE
             FROM users
             WHERE name = '" . $_POST["deleteUser"] . "'";
     mysqli_query($connection, $sql);

}
?>

But the browser doesn't render it(ie Chrome), maybe because it just can't on portions? Like to wait for the loop to complete and then to end with the last part of the form. Anyway, how could I make it work? Thanks mates...

Answer 1

Instead of using while loop you can use foreach this is where you can use foreach properly

Here is an example that might help you

 while ($row = mysql_fetch_assoc($result)) { 
   $rows[] = $row; 
 }
foreach($rows as $val){

   //Here populate your options like this
   echo '<option> '.$val["name"].' </option'
}

Hope this will help you out :)
