More than one htmlspecialchars string in PHP MySQL - php

Question

I have a table in MySQL where there is a row with this data.
id = 187
friendly name = i don't like mustard
filetype = exe
This first block of code below works perfectly, and echos text i don't like mustard into an HTML form. Similarly, if I change $row['friendlyname'] to $row['filetype'], text exe is echoed. All good, no issues yet.
<?php
$con = mysqli_connect('domain','user','pass','db');
$sql = "select * from installers where id=187";
$result = mysqli_query($con,$sql);
while($row=mysqli_fetch_array($result))
$friendlyname = htmlspecialchars(" ".$row['friendlyname']." ",ENT_QUOTES);
$con->close();
?>
<input type='text' value='<?php echo $friendlyname; ?>'>
The problem I'm having is if I try to echo both $row['friendlyname'] and $row['filetype'], only the variable that is listed first will be echoed. For example, in the below code, $row['friendlyname'] is listed before $row['filetype']. In this example, only $row['friendlyname'] (i don't like mustard) will be echoed. Similarly, if $row['filetype'] is listed before $row['friendlyname'], then only $row['filetype'] (exe) is echoed, and the second other HTML input form is empty.
<?php
$con = mysqli_connect('domain','user','pass','db');
$sql = "select * from installers where id=187";
$result = mysqli_query($con,$sql);
while($row=mysqli_fetch_array($result))
$friendlyname = htmlspecialchars(" ".$row['friendlyname']." ",ENT_QUOTES);
$filetype= htmlspecialchars(" ".$row['filetype']." ",ENT_QUOTES);
$con->close();
?>
<input type='text' value='<?php echo $friendlyname; ?>'>
<input type='text' value='<?php echo $filetype; ?>'>
Note 1: It doesn't matter the order of the input type forms. I ruled that out as the issue.
Note 2: If I were to replace $row['friendlyname'] and $row['filetype'] with the text I'm trying to echo, then it work (the below code). So, this definitely appears to be something with these $row variables.
<?php
$con = mysqli_connect('domain','user','pass','db');
$sql = "select * from installers where id=187";
$result = mysqli_query($con,$sql);
while($row=mysqli_fetch_array($result))
$friendlyname = i don't like mustard;
$filetype= exe;
$con->close();
?>
<input type='text' value='<?php echo $friendlyname; ?>'>
<input type='text' value='<?php echo $filetype; ?>'>

Answer 1

You have not added brackets into while loop so only first record is populated.
This block:
while($row=mysqli_fetch_array($result))
$friendlyname = htmlspecialchars(" ".$row['friendlyname']." ",ENT_QUOTES);
$filetype= htmlspecialchars(" ".$row['filetype']." ",ENT_QUOTES);
Should be:
while($row=mysqli_fetch_array($result)){
$friendlyname = htmlspecialchars(" ".$row['friendlyname']." ",ENT_QUOTES);
$filetype= htmlspecialchars(" ".$row['filetype']." ",ENT_QUOTES);
}
