Download link for each form? - php

Question

I have set a site where I display small panels have some text on it and download button, all these data are linked from mysqli I successfully printed them but How do I Do like if button click open a link from the database depends on the button clicked,
I'm developing a shop by the way, So How do I achieve this? Here's my code also:
<?php
$query = "SELECT * FROM `combolist`";
$results = mysqli_query($db, $query);
if ($results)
{
while($row = mysqli_fetch_array($results))
{
echo "<div class='panel panel-primary'>";
echo "<div class='panel-heading'><span class='glyphicon glyphicon-list-alt'></span><b> ".$row['comboTitle']."</b> ".$row['comboDesc']."";
echo "<form>
<button type='submit' name='purchase' class='btn btn-default btn-block'>Download 2¢</button>
</form><b>".$row['addedDate']."</b> - Added Date";
echo "</div>";
echo "</div>";
}
}
?>
<?php
if (isset($_GET['purchase']))
{
$inciar_sessiono = $_SESSION["username"];
if ($credits > 2) {
$credits--;
$do_update = "UPDATE `users` SET credits='$credits' WHERE username='$inciar_sessiono'";
$results = mysqli_query($db, $do_update);
// ON SUCCESS OPEN LINK FROM DATABAWES?
echo '<script type="text/javascript">
window.open("http://google.com");
</script>';
} else {
echo " no funds";
}
}
?>
<div class="panel panel-primary">
<div class="panel-heading"><span class="glyphicon glyphicon-list-alt"></span> <b>Combolists
</b>
<form>
<button type="submit" name="purchase" class="btn btn-default btn-block">Download 2¢</button>
</form>
</div>
</div>

Answer 1

If I understand your question correctly you need to identify which button the user is clicking on. If that is the case a hidden form field would be a good solution.
<input type="hidden" id="yourid" name="downloadlink_id" value="2">
Then you can use the value of the hidden field, in my case "2" and fetch the value using $_GET['downloadlink_id'] in a mysqli query to get the value and use it in a mysqli query.
Like this:
SELECT comboDownloadLink FROM table_name WHERE id=2
Edit: You can get the correct id and print it in your while-loop:
echo '<form>';
echo '<input type="hidden" id="yourid" name="downloadlink_id" value=".$row["id"]">';

Answer 2

So I suppose you have a link in your DB. You can add link it by $row['comboDownloadLink'] . So now if you want to add it to the button you can place the button into an <a> tag like <a href='".$row['comboDownloadLink']."' target='_blank'><button ... > </a> . Now it's redirecting your user to a blank page and starting the download.
