How do I display a query in PHP table - php

My code
<?php
include('ConnectToDb.php');
$query = "SELECT * FROM News WHERE NewsFlag = 1 ORDER BY PostDate DESC";
$arrCount = -1;
$result = mysql_query($query) or die(mysql_error());
while($row = mysql_fetch_array($result)){
$ID=$row['ID'];
$PostDate = $row['PostDate'];
$NewsHeader = stripslashes($row['NewsHeader'])
;
$NewsStart = stripslashes($row['NewsStart'])
;
echo "<hr>";
echo "<div>". date('j F Y',strtotime($PostDate)). "</div>";
echo "<p>";
$news_id = strval(sprintf("%1$04d",$ID));
$array = scanImageFolder("newsImages/newsThumbs",$news_id);
if(count($array)>0) {
echo "<img src='". $array[0]. "' alt='' />";
}
echo "<h2 style='text-align:center'><u><a href='latestnews_full.php?ID=$ID'>". $NewsHeader. "</a></u></h2>";
echo "<div style='text-align:left'><h3>";
echo $NewsStart. " ......<a href='latestnews_full.php?ID=$ID'>(more)</a><br />";
echo "<div style='text-align:center'>";
echo "</div>";
echo "</h3></div>";
}
?>
displays my data nicely on four lines with date at the top, then a picture, title and then description.
However, I want to display the data as a table like this
<table style="width: 100%">
<tr>
<td colspan="2">postDate here</td>
</tr>
<tr>
<td rowspan="2">picture here</td>
<td>newsHeader here</td>
</tr>
<tr>
<td>newsStart here</td>
</tr>
</table>
I'm not sure how to echo the table cells correctly and all of my attempts so far have resulted in a white page. Could anyone please enlighten me?

I'd suggest you to make your logic separated from your presentable part. Close the PHP tag once you are ready fetching the results, assigning var's etc, then:
<table style="width: 100%">
<?php
//yourcode
//...
//...
$NewsStart = stripslashes($row['NewsStart']);
$news_id = strval(sprintf("%1$04d",$ID));
$array = scanImageFolder("newsImages/newsThumbs",$news_id);
?>
<tr>
<td colspan="2"><?= date('j F Y',strtotime($PostDate)) ?></td>
</tr>
<tr>
<?php
if(count($array)>0) {
?>
<td rowspan="2"><img src='<?= $array[0] ?>' alt='' /></td>
<?php } ?>
<td><?= $NewsHeader ?></td>
</tr>
<tr>
<td><?= $NewsStart ?> </td>
</tr>
<?php } ?>
</table>
However, it's again not so clear, and I would suggest using a template engine. If you want I can post a code with assigning vars to Smarty and output your presentation in Smarty template

Quantity of every product outputs like 123. How can i put this in a table row table data

I am having a problem to convert my $quantity_total which is as example (113) from 3 different products.
I want it to be in a table like below.
I have been trying to use chunk_split and explode but if i was able to succeed in that. I wouldn't be able to make it dynamic.
<table>
<tr>
<th>Quantity</th>
</tr>
<tr>
<td>1</td>
</tr>
<tr>
<td>1</td>
</tr>
<tr>
<td>3</td>
</tr>
</table>
$total=0;
$item_count=0;
$arr = array();
$quantity_all = '';
while ($row = $stmt->fetch(PDO::FETCH_ASSOC)){
extract($row);
$arr[] = $row;
$_SESSION['cart-checkout'] = $arr;
$quantity=$_SESSION['cart'][$id]['quantity'];
$quantity_all .=$quantity;
$sub_total=$price*$quantity;
echo "<div class='cart-row'>";
echo "<div class='col-md-8'>";
echo "<div class='product-name m-b-10px'><h4>{$name}</h4></div>";
echo $quantity>1 ? "<div>{$quantity} items</div>" : "<div>{$quantity} item</div>";
echo "</div>";
echo "<div class='col-md-4'>";
echo "<h4>$" . number_format($price, 2, '.', ',') . "</h4>";
echo "</div>";
echo "</div>";
$item_count += $quantity;
$total+=$sub_total;
$_SESSION['total'] = $total;
$_SESSION['item-count'] = $item_count;
}
$_SESSION['quantity-all'] = $quantity_all;
Is this possible? And i need it to be dynamic. So if it were 10 different quantities. It would make 10 table rows.
I hope someone can help me, would really appreciate it a lot! It's the last thing to finish my e-commerce webshop.
As mentioned in my comment, I don't think this is good solution... but the function you're looking for is str_split. https://stackoverflow.com/a/9814389/296555
http://sandbox.onlinephpfunctions.com/code/0bbee53cafafc0d5e8954e07d0abc2c86c6c89a8
<?php
$rows = '156165165489465131';
echo '<table>';
echo '<tr><th>Quantity</th></tr>';
foreach (str_split($rows) as $row) {
echo "<tr><td>$row</td></tr>";
}
echo '</table>';
I dont know if this Is what you want, but you can try something like:
<table>
<tr>
<td>Quantity</td>
</tr>
<?php
$characters = str_split( (string) $quantity_total);
foreach($characters as $char){
echo "
<tr>
<td> $char </td>
</tr>
";
}
?>
</table>

Group list of array in a table [duplicate]

This question already has answers here:
Creating dynamic tables in HTML using MySQL and PHP
(2 answers)
Closed 11 months ago.
I want to show the list of an array in a table, I want to insert each ID in the ID column, each name in the "name" column, etc...
But it's showing all the content in single column, How I can fix it?
It shows like that right now:
[![enter image description here][1]][1]
PHP:
<table class="blueTable">
<thead>
<tr>
<th>ID</th>
<th>USER</th>
<th>MAIL</th>
</tr>
</thead>
<tfoot>
<tr>
<td colspan="3">
<div class="links">« <a class="active" href="#">1</a> 2 3 4 »</div>
</td>
</tr>
</tfoot>
<tbody>
<?php
$query = $db->query("SELECT * FROM users ORDER by id");
echo "<tr>";
while ($row = $query->fetch_array()) {
echo "<td>" . $row['id'] . "</td>";
echo "<tr><td>" . $row['username'] . "</td></tr>";
echo "<tr><td>" . $row['email'] . "</td></tr>";
}
?>
</tbody>
</table>
[1]: https://i.stack.imgur.com/jPTR8.png
change while() loop code like below:
$query = $db->query("SELECT * FROM users ORDER by id");
while($row = $query->fetch_array()){
echo "<tr>"; //put <tr> opening code inside, not outside
echo "<td>".$row['id']."</td>";
echo "<td>".$row['username']."</td>"; //remove <tr></tr>
echo "<td>".$row['email']."</td>"; //remove <tr></tr>
echo "</tr>"; //</tr> need to be added at last
}
Try this
<?php
$query = $db->query("SELECT * FROM users ORDER by id");
while($row = $query->fetch_array()){
?>
<tr>
<td> <?php echo $row['id'] ?></td>
<td> <?php echo $row['username'] ?> </td>
<td> <?php echo $row['email'] ?> </td>
</tr>
<?php
}

Why does edit button only function for row 1 in table php mysql

Why my edit button only function for row 1 only in my table?
When I click other rows it still show data from row 1 but the id is changed.
When I update row 1 the data updates in the database.
//fetch the record to be updated
if (isset($_GET['edit'])){
$entry_id = $_GET['edit'];
$edit_state = true;
$rec = mysqli_query($db, "select r.room_id, r.room_name, s.time_date, s.entry_id, s.time_exam, s.course_code, s.course_enroll from room r, schedule_entry s where s.room_id = r.room_id");
$record = mysqli_fetch_array($rec);
$time_date = $record['time_date'];
$time_exam = $record['time_exam'];
$course_code = $record['course_code'];
$course_enroll = $record['course_enroll'];
$room_name = $record['room_name'];
$room_id= $record['room_id'];
$entry_id= $record['entry_id'];
}
?>
<?php
if (mysqli_num_rows($results)>0){
while ($row = mysqli_fetch_array($results)) { ?>
<tr>
<td width="180"><?php echo $row['time_date']; ?></td>
<td width="70"><?php echo $row['time_exam']; ?></td>
<td width="200"><?php echo $row['course_code']; ?></td>
<td width="70"><?php echo $row['course_enroll']; ?></td>
<td><?php echo $row['room_name']; ?></td>
<td width="70">
<a class="edit_btn" href="entry.php?edit=<?php echo $row['entry_id']; ?>">Edit</a>
</td>
<td width="70">
<a class="del_btn" href="entryserver.php?del=<?php echo $row['entry_id']; ?>">Delete</a>
</td>
</tr>
<?php } }?>
you need to run the loop to update the ids,
<?php
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
?>
<td> <a class="edit_btn" href="entry.php?edit=
<?php echo $row['entry_id']; ?>">Edit</a></td>
<?php
}
}
?>
you have to evaluate your syntax, i think $row['entry_id'] have same value, so you must var_dump($row) form know all, like that
.... SOME CODE ....
<?php
if (mysqli_num_rows($results)>0){
while ($row = mysqli_fetch_array($results)) { ?>
<tr>
<td><? var_dump($row); ?>
</tr>
<?php } }?>
and after that i think you can solve your problem ...

Displaying an image in php

how to display blank if there is no image in a record.As i have inserted a record in database without an image but while fetching an record it is displaying an blank image in front end.It should not show any image if there is no image.Here is my code. If there is no image it should show only description.
Blogimage.php
<tbody>
<?php include "blogs.php" ;
while($row = mysql_fetch_array($result))
{?>
<tr>
<td><img src="admin/upload/<?php echo $row['image'];?>" height="100" style="width:60%;height:50%;"/></td>
</tr>
<tr>
<td><?php echo "<p style='width:60%;'>" .$row['blog_description']."</p>"; ?></td>
</tr>
<?php }?>
</tbody>
Blogs.php
$id=$_GET['title'];
$res = "SELECT * FROM blogs
WHERE blog_title='$id'";
$result=mysql_query($res);
try changing this
<img src="admin/upload/<?php echo $row['image'];?>" height="100" style="width:60%;height:50%;"/>
to this
<?php if($row['image']) echo "<img src='admin/upload/".$row['image']."' height='100' style='width:60%;height:50%;' />"; ?>
A couple of general points before we go into this
1) The MySql library you are using is old and busted - you should be using something newer - read this - the options are Mysql PDO and MySqli - I promise you, you will be glad you did, i use IDIORM as an interface and find it very good (Also helps prevent stuff in point 2 below!)
2) Your code can be SQL injected - more about that here - this is very bad :)
Below is an example, I have fixed the SQL injection problem, and put in some logic that would test to see if there is an image, if not, it will dump out a 'noimage.jpg' src value.
I have removed the include, and just simply put the code for blogs.php inline.
<tbody>
<?php
//START CODE FOR BLOGS.PHP
$query = sprintf("SELECT * FROM blogs WHERE blog_title='%s'",
mysql_real_escape_string($_GET['title']));
$result = mysql_query($query);
//END CODE FOR BLOGS.PHP
while($row = mysql_fetch_array($result))
{
if(!empty($row['image']) && strlen($row['image']) > 4)
{
$iamgeSrc = 'admin/upload/' . $row['image'];
}
else
{
$imageSrc = 'admin/upload/noimage.jpg';
}
?>
<tr>
<td>
<img src="<?php echo $imageSrc; ?>" height="100" style="width:60%;height:50%;"/>
</td>
</tr>
<tr>
<td>
<?php echo "<p style='width:60%;'>" .$row['blog_description']."</p>"; ?>
</td>
</tr>
<?php
}
?>
</tbody>
If you want no image to show at all, then this would work
<tbody>
<?php
//START CODE FOR BLOGS.PHP
$query = sprintf("SELECT * FROM blogs WHERE blog_title='%s'",
mysql_real_escape_string($_GET['title']));
$result = mysql_query($query);
//END CODE FOR BLOGS.PHP
while($row = mysql_fetch_array($result))
{
$image = '';
if(!empty($row['image']) && strlen($row['image']) > 4)
{
$image = '<img src="admin/upload/'.$row['image'].'" height="100" style="width:60%;height:50%;"/>';
}
?>
<tr>
<td>
<?php echo $image; ?>
</td>
</tr>
<tr>
<td>
<?php echo "<p style='width:60%;'>" .$row['blog_description']."</p>"; ?>
</td>
</tr>
<?php
}
?>
</tbody>

multiple arrays value fetching with session

Insert Is Fine But if I select this value from database All Values are fine but single values fetch array problem I don't know how to solve this task. Please Update this code asap.
This Is Insert Code .....
<?php
if(isset($_POST['sendmessage'])){
$entermessage = $_POST['teachermessage'];
$checkbox_user = $_POST['usernameallcheckbx'];
$arr = implode(',',$checkbox_user);
//$arr2 = explode(',',$arr);
$insert = mysql_query("INSERT into usermessages(fromteacher,toparent,messages) VALUES('".$_SESSION['username']."','$arr','$entermessage')");
if($insert == 1){
echo "<h1>successful</h1>";
}
else{
echo mysql_error();
}
}
?>
<form method="post">
<div style="float:left; width:450px;"><br/><br/>Message: <br/>
<textarea style="width:400px; height:300px;" name="teachermessage"></textarea><br/>
<input type="submit" value="Send" name="sendmessage" /></div>
<div style="float:left; with:200px; padding-top:55px;">
<table>
<tr>
<?php
$select_query1 = mysql_query("SELECT * FROM register_user WHERE teacher='$teachername'");
while($chckbx=mysql_fetch_array($select_query1))
{
?>
<td><?php echo "<input type='checkbox' name='usernameallcheckbx[]' value=". $chckbx['userid']." />"; ?></td>
</tr>
<tr>
<td><?php echo $chckbx['parent_fname']." ".$chckbx['parent_lname']; ?></td>
</tr>
<?php
}
?>
</table>
</div>
</form>
And This Is Select Code....
<h2>Messages</h2>
<?php
$select_query3 = mysql_query("SELECT * FROM usermessages");
$fetch= mysql_fetch_array($select_query3);
$data=$fetch['toparent'];
$arr=explode(',',$data);
//$userids=explode(',',$data);
$sessionshow=$_SESSION['userid'];
$userids=in_array("$sessionshow",$arr);
$select_query2 = mysql_query("SELECT * FROM usermessages WHERE toparent in ('$userids')='".$_SESSION['userid']."'");
?>
<table border="0" cellpadding="0" cellspacing="0">
<tr>
<th>Teacher Name</th>
<th>Message</th>
</tr>
<?php
while($fetch_name2=mysql_fetch_array($select_query2))
{
echo "<tr>";
echo "<td>".$fetch_data=$fetch_name2['fromteacher']."</td>";
echo "<td>".$fetch_data=$fetch_name2['messages']."</td>";
echo "</tr>";
}
?>
</table>
I have only put this as an answer to show some incorrect code - remove fetch data from your loop as it doesn't do anything
while($fetch_name2=mysql_fetch_array($select_query2))
{
echo "<tr>";
echo "<td>".$fetch_name2['fromteacher']."</td>";
echo "<td>".$fetch_name2['messages']."</td>";
echo "</tr>";
}
even better is use of a HEREDOC:
while($fetch_name2=mysql_fetch_array($select_query2))
{
echo <<<EOF
<tr>
<td>{$fetch_name2['fromteacher']}</td>
<td>{$fetch_name2['messages']}</td>
</tr>
EOF;
}
I really can't figure out what you're trying to do, but maybe this is the query you want:
SELECT * FROM usermessages WHERE FIND_IN_SET('$sessionshow', toparent)
FIND_IN_SET(str, strlist) searches the comma-separated list in strlist for an element that equals str, and returns the position in the list; if it's not found it returns 0, which counts as false.
I can't see any purpose to any of the code that uses $select_query3.
