// FYI -> Here i am using only two fields : voice_sku & voice_name

<table width=”100%” cellpadding=”6″ cellspacing=”0″>
<thead>
<tr>
<th>Voice Sku</th>
<th>Voice Name</th>
<th>Remove</th>
</tr>
</thead>

<tbody>

<?php
session_start();
$voice_sku = ”;
$voice_name = ”;

if(isset($_POST[‘voice_sku’])&& isset($_POST[‘voice_name’]))
{
// print_r($_POST);
// die();

$voice_sku = $_POST[‘voice_sku’];
$voice_name = $_POST[‘voice_name’];
$_SESSION[‘voice_sku’] = $voice_sku;
$_SESSION[‘voice_name’] = $voice_name;

}
var_dump($_SESSION);
?>

<tr>
<td colspan=”5″>
<span style=”float:right;text-align: right;”>
<!– –>
</span>
</td>
</tr>

@ginerjmJul 10.2019 — You are so difficult to understand. But I will ask this. YOu are showing us an html table layout but you only have one td tag in it. Why not two more td tags showing the two inputs you received? Isn't that what you are asking about???

PLEASE - stop mixing your html code in with your php code. It makes no sense to keep doing this even after being told how inappropriate it is.

@ginerjmJul 11.2019 — Are you TRYING to say that you want to have a button on each row to remove that row of data from the table it came from?

@ginerjmJul 15.2019 — Didn't bother to read thru ALL THAT CODE but....

I build my html table as part of my query results loop and add a last column to the row to hold the button(s) for that row. Each row (<tr>....</tr>) is wrapped by a form tags so that the buttons act upon the current row of data only. BTW as I a build that table I am NOT OUTPUTTING THE RESULTS. I merely assign then to one big variable and then I output that variable along with ALL THE REST OF MY HTML so that I keep my logic (php) separated from the presentation (html) code.

@Aveeva7authorJul 19.2019 — Anyone help me with my workout :

my_cart.php:

&lt;?php<br/>
header('Content-Type: text/html; charset=utf-8');<br/>
session_start();<br/>
session_regenerate_id();

<i> </i><CODE>echo '
<i> </i>&lt;!DOCTYPE html&gt;
<i> </i>&lt;html lang="en"&gt;
<i> </i> &lt;head&gt;
<i> </i> &lt;meta charset="utf-8"&gt;
<i> </i> &lt;metaname="viewport"content="width=device-width,height=device-height,initial-scale=1"&gt;
<i> </i> &lt;title&gt;Playlist&lt;/title&gt;
<i> </i> &lt;/head&gt;

<i> </i> &lt;body&gt;
<i> </i> &lt;form id="playlist" action="playlist_action.php" method="post"&gt;
<i> </i> &lt;table id="playlist"&gt;
<i> </i> &lt;caption&gt;Play List&lt;/caption&gt;
<i> </i> &lt;thead&gt;
<i> </i> &lt;tr&gt;
<i> </i> &lt;th scope="col"&gt;Voice SKU&lt;/th&gt;
<i> </i> &lt;th scope="col"&gt;Voice Name&lt;/th&gt;
<i> </i> &lt;th scope="col"&gt;Action&lt;/th&gt;
<i> </i> &lt;/tr&gt;
<i> </i> &lt;/thead&gt;

<i> </i> &lt;tbody&gt;';
<i> </i> foreach ($_SESSION['playlist'] as $key =&gt; $value)
<i> </i> {
<i> </i> $key = htmlspecialchars($key);
<i> </i> echo '
<i> </i> &lt;tr&gt;
<i> </i> &lt;th scope="row"&gt;', $key, '&lt;/th&gt;
<i> </i> &lt;td&gt;', htmlspecialchars($value), '&lt;/td&gt;
<i> </i> &lt;td&gt;&lt;button name="delete" value="', $key, '"&gt;Delete&lt;/button&gt;&lt;/td&gt;
<i> </i> &lt;/tr&gt;';
<i> </i> }
<i> </i> echo '
<i> </i> &lt;/tbody&gt;
<i> </i> &lt;/table&gt;
<i> </i> &lt;/form&gt;
<i> </i> &lt;/body&gt;
<i> </i>&lt;/html&gt;';

and

playlist_action.php

<br/>
&lt;?php<br/>
header('Content-Type: text/html; charset=utf-8');<br/>
session_start();<br/>
session_regenerate_id();

<i> </i><CODE>if (array_key_exists('playlist_action', $_POST)) {
<i> </i> switch ($_POST['playlist_action']) {
<i> </i> case 'delete':
<i> </i> if (array_key_exists($_POST['delete'], $_SESSION['playlist']) {
<i> </i> unset($_SESSION['playlist'][$_POST['delete']]);
<i> </i> // notify user of successful delete
<i> </i> } else {
<i> </i> // notify user of non-existent key in the playlist
<i> </i> }
<i> </i> default:
<i> </i> // handle invalid/unknown action here.
<i> </i> }
<i> </i>}
<i> </i>?&gt;

my output:

**|Parse error: syntax error, unexpected 'unset' (T_UNSET) in C:wampwwwvoice_bankplaylist_action.php on line *10*|**

Success!
