PHP / MySQL - Query not fetching any data - php

I have been trying to set up a page that lists prices of items from a table in a database. Here is my code:
<?php
$querylist = mysql_query("SELECT item_name,image,price,added_by FROM values");
while($row = mysql_fetch_array($querylist))
{
echo '<div class="post rareitem" style="margin-right: 15px;float: left;">
<div class="rarename">
<strong>';
// Shows Item Name
echo $row['item_name'];
echo '</strong>
</div>';
// Shows Item Image
echo '<div class="rareimage" style="background-image: url(/app/tpl/skins/Mango/images/values/rares/';
echo $row['image'];
echo ');"></div>';
// Shows Item Price
echo '<div class="rarecontrols">
<div class="coinsbox"></div>
<span>
<b> <b>Credits: </b> </b> ';
echo $row['price'];
echo '</span>';
// Shows Who Added the Item
echo '<div class="addedbox"></div><b><b><span><font color="#c93734"><font color="#c93734">Added By: </font> </font>';
echo $row['added_by'];
echo '</span></b></b>
</div>
<div class="clear"></div>
</div>';
}
?>
There is another chunk of code (shown below) that I have based this off of, and it works perfectly fine. I can't seem to get this to work though. I believe it has something to do with the SQL, the syntax, or something. No matter what I do, it produces absolutely no results, yet the code below results exactly as planned. I know for a fact it is not a connection issue because the below code can be placed on the same exact page as the above one and it works fine, however the above does not.
<?php
$querylist = mysql_query("SELECT id,username,motto,country,look,rank,account_created,role,account_created,online,last_online FROM users WHERE rank='9' ORDER BY ID LIMIT 20");
while($row = mysql_fetch_array($querylist))
{
echo '
<div class="team">';
// Showing Avatar
echo '<div style="float: left; margin-top:-1px;height: 60px; width: 64px; background: url(http://www.habbo.nl/habbo-imaging/avatarimage?figure=';
echo $row['look'];echo "&action=wav&direction=3&head_direction=3&gesture=sml&size=m) no-repeat 0px -10px";
echo "\"/>";
echo "<img alt=\"badge\" src=\"/app/tpl/skins/habbo/images/icons/";
echo $row['online'];echo ".gif\"></div>";
// Flags
echo "<br/><img src=\"/app/tpl/skins/habbo/images/icons/flags/";
echo $row['country'];echo ".png";
echo '" style="float:right;" /> <b><uf>';
echo $row['username'];echo "</u></b>";
// Bans & Ticket Count
$Bans = mysql_query("SELECT * FROM `bans` WHERE `added_by` = '" . $row['username'] . "'");
$BanCount = mysql_num_rows($Bans);
$Tickets = mysql_query("SELECT * FROM `moderation_tickets` WHERE `moderator_id` = '" . $row['id'] . "'");
$TicketCount = mysql_num_rows($Tickets);
//Role
echo "<br/><gb>Role: </b><fi> ";
echo $row['role'];echo "";
echo "</i>";
// Echoing bans & Tickets
echo "<br/><gb>Bans: </b><fi> ";
; echo $BanCount;
echo "</i>";
echo " <gb>Tickets: </b><if>";
; echo $TicketCount;
echo "</i>";
echo "</div>";
}
?>
Thanks in advanced, any assistance will be greatly appreciated!

values is Reserved Words in mysql it should be on backtick
SELECT item_name,image,price,added_by FROM `values`
And stop using mysql it is deprecated. Instead use mysqli or PDO

How to get my table data in a row without tables

I have a database and I am trying to display data from the table all in one box.
I am not sure if there is another way besides tables but I am trying to do something like this.
I am using roblox as an example.
Example:
Right now this is my code for the table.
<div class="row2">
<div class="column">
<?php
include_once("includes/config.php");
$sql = "SELECT * FROM communities";
$result = $conn->query($sql);
if ($result->num_rows > 1) {
while($row = $result->fetch_assoc()) {
echo '<hr />';
echo '<table>';
echo '<tr><td>Name: </td><td>'.$row["name"].'</td></tr>';
echo '<tr><td>Discription:</td><td>'.$row["description"].'</td></tr>';
echo '<tr><td></td><td><img src="'.$row["logo"].'" width="100px" /></td></tr>';
echo '</table>';
echo '<button name="button">Join</button>';
echo '<hr />';
}
}
?>
</div>

How to check table cell in database and output results?

I am bit new to php and sql.
I am simply reading from a database table and echoing images to a page. The images are then styled with a text aligned in the middle saying 'Play Video'.
In the table 'adcTable' some entries do not have a video stored.
I would like to have the rows/entries with video say 'Play Video' and the ones without just show the image.
Not to sure how bess to explain. Hope to get some assistance.
<php
$sql = "SELECT client_id, images, video FROM adcTable";
$result = $conn->query($sql);
$count = 1;
echo "<table border = '0' width='720'><tr>";
while($row = $result->fetch_assoc()) {
echo "<td><div class='ccontainer'>"; ?><img class="cimage" src= "<?php echo $row ["images"];?> " ><?php echo "
<div class='middle'>
<div class='text'>Play Video</div>
</div>
</div>
</td>";
if ($count++ % 2 == 0) {
echo "</tr><tr>";
}
echo "</tr></table>";
?>
Thanks guys, I was able to use the example provided by BusinessPlanQuickBuilder to solve.
$sql = "SELECT client_id, files, file FROM adcTable";
$result = $conn->query($sql);
$count = 1;
echo "<table border = '0' width='720'><tr>";
while($row = $result->fetch_assoc()) {
if ($row['file'] == "VidUploads/"){
echo "<td>"; ?><img class="cimage" src= "<?php echo $row ["files"];?> " ><?php echo "
</td>";
echo '<script type="text/javascript">',
'$( ".text" ).css( "border", "3px solid red" );',
'</script>';
} else{
echo "<td><div class='ccontainer'>"; ?><img class="cimage" src= "<?php echo $row ["files"];?> " ><?php echo "
<div class='middle'>
<div class='text'>Video</div>
</div>
</div>
</td>";
}
if ($count++ % 2 == 0) {
echo "</tr><tr>";
}
}
echo "</tr></table>";
?>
Use if empty condition on video column. This is the fundamental code, add your formatting as required.
<?php
while($row = $result->fetch_assoc()) {
if (empty ($row['video']) ) {
echo $row ["images"];
} else {
echo "Play Video";
}
}
?>

Activating certain PHP code before a section of the page is Created

I am working with an HTML webpage connected to a database and using PHP. I have in a div at the top a variable that doesn't get properly set until some PHP later in the document. Is there a way to make the div build after the later PHP, but still be where it should be at the top of the page?
Here's the code that uses the variables
<div id="HeaderRight">
<div id="HeaderRight">
<?php
echo '<a href="../Cart/index.php" class="header">
<img src="../Images/shoppingcart.gif" height="18" width="127" border="0" align="ABSMIDDLE" /> Contains '.$_SESSION["num_items"].' Items</a>'
?>
</div>
Here's the code that sets the variables
<?php
echo '<TABLE WIDTH="100%" BGCOLOR="#FFFFFF" ALIGN = "RIGHT" BORDER = "1">';
echo '<TR BGCOLOR = "818996" HEIGHT = "25"><TD>Product</TD><TD>Availability</TD> <TD>Qty</TD><TD>Price</TD><TD>Total</TD></TR>';
$strTotalPrice = 0;
for ($i=0; $i<$_SESSION['num_products']; $i++) {
$strSQL = "SELECT * FROM products WHERE ProductCode = '".$_SESSION['cart'][$i]['name']."'";
$rsProd = mysql_query($strSQL)
or die($db_name . " : " . $strSQL . " : " . mysql_error());
$rowProd = mysql_fetch_array($rsProd);
$strSQLDetails = "SELECT * FROM pagedetails WHERE Category = '".$rowProd["Category"]."'";
$rsDetails = mysql_query($strSQLDetails)
or die($db_name . " : " . $strSQLDetails . " : " . mysql_error());
$rowDetails = mysql_fetch_array($rsDetails);
// End Of "Retrieve Desired Record Set"
echo ' <TR HEIGHT = "' .$rowProd["ThumbnailHeight"]. '" ><TD style="vertical-align:middle"><img src="../'.$rowProd["Department"].'/Images/'.$rowProd["ProductCode"].'_sm.jpg" align = "left" border="0" height = "'.$rowProd["ThumbnailHeight"].'" width="100" hspace="25" />
<br><a href = "../Products/Products.php?PageID='.$rowDetails["PageID"].'" >'.$rowProd["ProductName"].'</a>
</TD>';
$strAvailability = "";
$strQuantity = 0;
if($rowProd["Stock"] < $_SESSION["cart"][$i]["qty"]){
$strAvailability = "Only " .$rowProd["Stock"]. " in Stock, Quantity Changed";
$strQuantity = $rowProd["Stock"];
$_SESSION["cart"][$i]["qty"] = $rowProd["Stock"];
}
else{
$strAvailability = "In Stock";
$strQuantity = $_SESSION["cart"][$i]["qty"];
}
echo '<TD ALIGN = "center">'.$strAvailability.'</TD>';
echo '<TD ALIGN = "center">
<input type="text" name="txtQuantity" size="2" maxlength="2" value ='.$strQuantity.'>';
echo '<form action="index.php?=?product='.$rowProd["ProductCode"].'&quantity=1" method="post">
<input type="submit" name="submit" value="Update">
</form>
</TD>';
$strPrice = $rowProd["RegPrice"] * $strQuantity;
$strTotalPrice += $strPrice;
echo '<TD ALIGN = "center">$'.$rowProd["RegPrice"].'.00</TD>';
echo '<TD ALIGN = "center">$'.$strPrice.'.00</TD></TR>';
//echo '( <a href=index.php?product=' . $_SESSION['cart'][$i]['name'] . '&quantity=1>+</a> )';
}
As Rocket Hazmat points out, it is a good idea to run all of your PHP code before rendering the HTML. Without rewriting your current code, you can achieve this with some output buffering:
<?
// add this block
function firstDiv() {
ob_start();
?>
<div id="HeaderRight">
... <? echo $_SESSION["num_items"]; ?> ...
</div>
<?
// ... and this block
$_SESSION["firstDiv"] = ob_get_contents();
ob_end_clean();
} // end of firstDiv
?>
and the same with the rest of your page
<?
function restOfYourPage() {
ob_start();
?>
<TABLE> ... <? $_SESSION["num_items"] = 666; ?> ... </TABLE>
<?
$_SESSION["restOfYourPage"] = ob_get_contents();
ob_end_clean();
} // end of restOfYourPage
?>
Then you can run the php code in reverse order, but display it in normal order:
<?
restOfYourPage();
firstDiv();
echo $_SESSION["firstDiv"];
echo $_SESSION["restOfYourPage"];
?>

Show data from db into another div (from selected $rowId )

I'm having problems with showing data from a selected row into another div.
Meaning I'm showing eg forename and lastname, when the user clicks on the name (as a link), I would like to show more data from the Id chosen, and I would like it to be shown in a div box below.
See the site here: http://kristoff.it/onlinecoaching/
And my code:
<div class="greenBox1">
<h1>1 - VÆLG DIN ONLINE COACH</h1>
<div class="whiteBox1">
<?php
$sql = "SELECT * FROM coach ";
$coachId = $row["coachId"];
$fornavn = $row["fornavn"];
$efternavn = $row["efternavn"];
$result = mysql_query($sql);
while($row=mysql_fetch_assoc($result))
{
echo '<table border="0" align="left" height="100">';
echo '<tr>';
echo '<td width="95" rowspan="2" align="center" valign="middle"><img src="' . $row['imgUrl'] . '" width="85" height="85" alt="' . $row['imgAlt'] . '"/>' . '</td>';
?>
<!-- here I'm trying to write the id of the selected name to the div box below -->
<?
echo '<td><h2>' . $row['fornavn'] . $row['efternavn'] . '</h2></td>';
echo '</tr>';
echo '<tr>';
echo '<td valign="top" width="190"><p>' . $row['beskrivKort'] . '<br></p></td>';
echo '</tr>';
echo '</table>';
}
?>
</div>
</div>
<div class="greenBox2">
<h1>2 - BOOK TID I COACHENS KALENDER</h1>
<div class="whiteBox2" id="whiteBox2">
<!-- here would like the more data to show -->
</div>
</div>
Regards Maria
In your website, your URLs are empty. You need to put your ID.
echo '<td><h2>' . $row['fornavn'] . $row['efternavn'] . '</h2></td>';
With that URL, you will send the ID as a GET variable.
You must then request your data if the ID is set.
<div class="whiteBox2" id="whiteBox2">
<?php
if (isset($_GET['id']))
{
$sql = "SELECT * FROM coach WHERE coachId=" . (int)$_GET['id'];
// Do your stuff...
echo "Hello";
}
?>
<!-- here would like the more data to show -->
</div>

?>
</p>
</div>
<div class="footer"><a href="logout.php"><br />
Logout</a> | Index | Back</div>
</div>
</body>
</html>
I am relatively new to PHP, and i was curious as to whether a certain function is possible. I have a keyword Search and the code for the results page is above. I would like to bold wherever the $kword variable appears on the page. is this possible?
Thanks
You can create a function to do so, and call it prior to echo'ing the variables.
Instead of: $info['question'] use boldText($info['question'], $kword)
function boldText($text, $keyword) {
return str_ireplace($keyword, "<strong>$keyword</strong>", $text);
}
As a side note, don't forget to escape $kword with mysql_real_escape_string() before using it in a SQL query, or even better, consider using MySQLi or PDO since mysql extension is strongly discouraged
Can you use something like this in each of your Print statements?
str_replace($kword, "<b>$kword</b>", $info[...])
(or CSS e.g.
<span style='font-weight:bold'>...</span>
if you prefer).
