I've read about the nl2br() command but they echo out the variable to make it work but my variable is inside a list that I echo out.
Should I somehow put the nl2br() command in my if statement where I'm setting up the output or should I be looking somewhere else for my answer.
I have made 2 extra detail variables to output so I get 3 lines of text for the description of my product but there has to be a better way of doing it than that. I would think 1 detail variable with all the info would be the preferred way of doing it
I have tried to search for it but I'm afraid I'm just not asking the right question so any help in the right direction is appreciated.
<?php require_once './connections/connect_mysqli.php';
$conn = dbConnect('read');
$sql = "SELECT * FROM products ORDER BY id ASC LIMIT 6 ";

$flatlist = "";
while($row = $result->fetch_array(MYSQLI_ASSOC)){
$id = $row["id"];
$product_name = $row["product_name"];

Want to point out you close the details <p> before the 2nd and 3rd lines. You probably want to close that after third line.
<p style=font-size:14px;>' . $details . '<!-- remove here: </p> --><br />
' . $details2 . '<br />
' . $details3 . '<br /><!-- add here: --></p>
If you keep your same database structure, you can define into one variable after retrieving like:
$details = $row["details"] . '<br/>' . $row['details2'] . '<br/>' . $row['details3'];
And then just refer back to $details later on.
Why don't you want to use nl2br()? This would allow you to store multiple lines all into details column. Then you would just use:
$details = nl2br( $row["details"] );`
Here are my edits to your code:
<?php require_once './connections/connect_mysqli.php';
$conn = dbConnect('read');
$sql = "SELECT * FROM products ORDER BY id ASC LIMIT 6 ";
$result = $conn->query($sql) or die($conn->error);

while($row = $result->fetch_array(MYSQLI_ASSOC)){
$id = $row["id"];
$product_name = $row["product_name"];
$details = $row["details"] . '<br/>' . $row['details2'] . '<br/>' . $row['details3'];
$price = $row["price"];
if ($i % 4 == 0) {
$flatlist .='<tr><td width="250px" align="center"><img src="images/' . $id . '.jpg"><br/>

I'm new to php and I'm working with a tutorial about showing images dynamically on the page, it works fine but it shows them vertically and I would like them to be horizontal. I created a page with code to do that but I can't seem to figure out where to insert the code to get the images to show.
Thanks for any help.
Vertical output looks like this
$dynamicList = "";
$sql = mysql_query("SELECT * FROM products ORDER BY date_added ASC LIMIT 6");
while($row = mysql_fetch_array($sql)){
$id = $row["id"];
$product_name = $row["product_name"];
$price = $row["price"];
$details = $row["details"];
$date_added = strftime("%b %d, %Y", strtotime($row["date_added"]));
$dynamicList .= '<table width="1000px" border="0" cellspacing="0" cellpadding="6" align="center">
<tr>
<td width="1000px" align="center"><img style="border:#666 0px solid;" src="images/' . $id . '.jpg" width="50%" height="50%" alt="' . $product_name . '" width="77" height="102" border="1" /></td>
<td width="83%" valign="top">' . $product_name . '<br />
$' . $price . '<br /> $' . $details . '<br />
order</td>
</tr>
</table>';
}
mysql_close();
?>
Grid Output
$sql = mysql_query("SELECT * FROM products ORDER BY id ASC LIMIT 15");
$i = 0;
// Establish the output variable
$dynamiclist = '<table width="1000px" border="1" cellspacing="2" cellpadding="10" align="center">';
while($row = mysql_fetch_array($sql)){
$id = $row["id"];
$product_name = $row["product_name"];
$details = $row["details"];
$price = $row["price"];
if ($i % 3 == 0) { // if $i is divisible by our target number (in this case "3")
$dynamiclist .= '<tr><td>' . $product_name . '</br>' . $details . '</br>' . $price . '</td>';
} else {
$dynamiclist .= '<td>' . $product_name . '</td>';
}
$i++;
}
$dynamiclist .= '</tr></table>';
?>

I seem to be getting Undefined offset 1 error when I hit submit. I have been trying to play with the numbers but nothing seems to help. I added a fourth column right after the commented last name. Before the addition the code worked. I realized later on that I needed that third column. Ever since then I get an error and can not update the sql table.
Thank you in advance,
Avi

So I'm trying to make a cart for my website (nothing too special, uni project).
Currently I have
$product_id = $row["ID"];
$product_name = $row['name'];
$product_price = $row['price'];
$product_image = $row['img'];
$imgurl = ".\img\\".$product_image;
if ($i % 3 == 0) { // if $i is divisible by our target number (in this case "3")
$dyn_table .= '<tr><td align="center" valign="middle" width="350">'. "<img src=$imgurl width='100' hieght='100'> <br />" . $product_name . '<br /> £'.$product_price . '<br /><a href="./cart.php?product="$product_id"&action=add" />Add to Card</a></td>';
} else {
$dyn_table .= '<td align="center" valign="middle" width="350">'. "<img src=$imgurl width='100' hieght='100'> <br />" . $product_name . '<br /> £'.$product_price . '<a href="./cart.php?product=$product_id&action=add" />Add to Card</a></td>';
I need to have the product ID inserted in href where I have $product_id
<a href="./cart.php?product=$product_id&action=add" />Add to Card</a>
Currenly, it loads the links as domain.com/cart.php?product=$product_id&action=add
you can use variable name between quotes
provided if it is a single quoted you have to put {} around variable
else if it is a double quotes you can directly use the varibale
if ($i % 3 == 0) {
$dyn_table .= "<tr><td align='center' valign='middle' width='350'>". "<img src=$imgurl width='100' hieght='100'> <br />" . $product_name . "<br /> £".$product_price . "<br />
<a href='./cart.php?product={$product_id}&action=add' />Add to Card</a></td>";
} else {
$dyn_table .= "<td align='center' valign='middle' width='350'>". "<img src=$imgurl width='100' hieght='100'> <br />" . $product_name . "<br /> £".$product_price . "<a href='./cart.php?product={$product_id}&action=add' />Add to Card</a></td>";
}
The variable has to be extracted from the string, in PHP, so:
<a href="./cart.php?product='.$product_id.'&action=add" />Add to Card</a>
Like you did for your other variables.
this:
$dyn_table .= '<tr><td align="center" valign="middle" width="350">'."<img src=$imgurl width='100' hieght='100'><br />" . $product_name.'<br /> £'.$product_price .'<br /><a href="./cart.php?product=" .$product_id. "&action=add." />Add to Card</a></td>';
Your original problem was that you didn't jump out of single quotes properly to add $product_id in, however there's another instrumental problem in your code.
You should either use all '' single quotes or all "" double quotes, not a combination of both. It makes it hard to read and is unnecessary regardless.
Therefore, it should be either
$dyn_table .= '<tr><td align="center" valign="middle" width="350"><img src="' . $imgurl . '" width="100" hieght="100"> <br />' . $product_name . '<br /> £' . $product_price . '<br /><a href="./cart.php?product=' . $product_id . '&action=add" />Add to Card</a></td>';
or
$dyn_table .= "<tr><td align=\"center\" valign=\"middle\" width=\"350\"><img src=\"$imgurl\" width=\"100\" hieght=\"100\"> <br />$product_name<br /> £$product_price<br /><a href=\"./cart.php?product=$product_id&action=add\" />Add to Card</a></td>";
In this case, I'd probably use single quotes so I don't have to escape all the double quotes in the HTML, or perhaps even a heredoc, but I won't get into those for now.
Your code for single quotes would be
if ($i % 3 == 0) { // if $i is divisible by our target number (in this case "3")
$dyn_table .= '<tr><td align="center" valign="middle" width="350"><img src="' . $imgurl . '" width="100" height="100"> <br />' . $product_name . '<br /> £' . $product_price . '<br /><a href="./cart.php?product=' . $product_id . '&action=add" />Add to Card</a></td>';
} else {
$dyn_table .= '<td align="center" valign="middle" width="350"><img src="' . $imgurl . '" width="100" hieght="100"> <br />' . $product_name . '<br /> £' . $product_price . '<a href="./cart.php?product=' . $product_id . '&action=add" />Add to Card</a></td>';
I'd suggest you look up heredocs though, you may find those easier.
I have a system where users can send and receive messages and I need to make a way for them to directly reply to the messages.
This is a test code to make the page echo what should be retrieved and set as a session, but it is not echoing anything.

I need the session $_SESSION['reply'] to be set as the variable $username2 and it does not seem to be working.
Move session_start(); on top of the PHP code. You are accessing $_SESSION['reply'] = $username2; before that which wont work.
What I was doing was incorrect. I had to move
$_SESSION['reply'] = $row['from'];
$username2 = $_SESSION['reply'];`
from after the query to
while ($row = mysqli_fetch_array($data)) {
$_SESSION['reply'] = $row['from'];
$username2 = $_SESSION['reply'];`
and then it echo'd correctly. Thanks for the help from everyone :)
basically I've written the following but I'm wondering what the best way to get $message_id = to the $row['id'] you click on to view an inbox message. If I just statically set $message_id = to say 39 and click on the row that's $row['id'] is 39 it'll open the message.
Basically what it does is list inbox messages I have, and anchor tag them with its row id to be used in the header to show the full contents of that message.
<p>
<?php
$message_id = "39";
if (isset($_GET[$message_id]) && empty($_GET[$message_id])) {
$username = $user_data['username'];
$get_message = mysql_query("SELECT * FROM `users_inbox` WHERE `id` = '$message_id' AND `send_to` = '$username'");
$get_message_result = mysql_fetch_array($get_message);
echo '<h1><u>' . $get_message_result['subject'] . '</u></h1>';
echo $get_message_result['sent_from'] . '<br />';
echo $get_message_result['body'] . '<br />';
echo 'Back';
}
$username = $user_data['username'];
$result = mysql_query("SELECT * FROM `users_inbox` WHERE `send_to` = '$username'");
?>
<table border="1">
<tr>
<td>From</td>
<td>Subject</td>
<td>Date</td>
</tr>
<?php
while($row = mysql_fetch_array($result))
{
echo
'<tr>' .
'<td>' . $row['sent_from'] . '</td>' .
'<td>' . $row['subject'] . '</td>' .
'<td>' . $row['post_date'] . '</td>' .
'</tr>';
}
?>

</p>
Anyone know if this is even possible, as I know code is read from top to bottom and as far as I'm aware you cant go back upwards at all.
I assume that the $user_data['username'] is set or available,if yes then you could pass a variable name of you choice which points the message id instead of sending only the id (eg: i am setting it as msg_id ), Now you can access the message id via $_GET['msg_id']
<p>
<?php
$username = $user_data['username'];
if ( isset( $_GET['msg_id'] ) ) {
$get_message = mysql_query("SELECT * FROM `users_inbox` WHERE `id` = '$message_id' AND `send_to` = '$username'");
$get_message_result = mysql_fetch_array($get_message);
echo '<h1><u>' . $get_message_result['subject'] . '</u></h1>';
echo $get_message_result['sent_from'] . '<br />';
echo $get_message_result['body'] . '<br />';
echo 'Back';
}else{
$result = mysql_query("SELECT * FROM `users_inbox` WHERE `send_to` = '$username'");
?>
<table border="1">
<tr>
<td>From</td>

<?php
while($row = mysql_fetch_array($result))
