Display all data in dropdown from database - php

Question

i am using Php/Mysql , i have the client table and trying to display data in a drop down list. Unfortunately, only one client is displayed in drop down which i have the total of 3 clients. Why only one ? For example : Michael King, Michael Jordan , Michael John when i select all the data from table and make an output to display in dropdown, Michael John is only in the dropdown.
Here my Mysql code :
//All data is selected from client_tb
<?php
$sql = "SELECT * FROM client_tb";
$result = $conn->query($sql);
while($row=mysqli_fetch_array($result))
{
$id = $row['id'];
$lname = $row['lname'];
$fname = $row['fname'];
}
?>
//my dropdown which will show the clients from client_tb but only one will appear.
<option value ="<?=$lname?><?=$fname?>"><?=$lname?> , <?=$fname?> </option> </select><br><br>

Answer 1

You can also achieve dropdown outside the while loop. Try this:
$sql = "SELECT * FROM client_tb";
$result = $conn->query($sql);
$options =array();
while($row=mysqli_fetch_array($result))
{
$options[] =$row;
}
Your dropdown:
<select name="">
<?php
foreach($options as $option):
echo '<option value ="'.$option['lname'].''.$option['fname'].'">'.
$option['lname'].','.$option['fname'].'</option>';
endforeach;
?>
</select>

You could also add your db query into a function , then call it.
function myFunction() {
$sql = "SELECT * FROM client_tb";
$result = $conn->query($sql);
while($row=mysqli_fetch_array($result))
{
$myvalues[] =$row;
}
return $myvalues;
}
Now the dropdown,
Note the options are inside the loop
<select name="">
<?php foreach($myvalues as $myvalue) {
echo '<option value="'.$myvalue['lname'].''.$myvalue['fname'].'">'.
$myvalue['lname'].','.$myvalue['fname'].'</option>';
}
?>
</select>
