Create Dynamic Table in PHP - php

I'm faced with a very simple task but for some reason the solution is eluding me, probably because my PHP is not good.
I have a table that has 1 header which spans across 4 columns. In the first column it would be static data, (i.e. headers so to speak but only in the first column). What I need is to populate the 2nd column and so on based on the results returned. I'm building a table that when a product is compared it will populate a column with information related to the product
<table id="price-compare" class="device-compare" border="1">
<caption>Price</caption>
<?php
$rows = 3;
$cols = 4;
for($tr=1;$tr<=$rows;$tr++){
echo "<tr>";
for($td=1;$td<=$cols;$td++){
echo "<td>row: ".$tr." column: ".$td."</td>";
}
echo "</tr>";
}
?>
<tr>
<td class="left-header"><?php echo $phones->field('name'); ?></td>
<td><sup>$</sup><?php echo $phones_retail; ?></td>
</tr>
<tr>
<td class="left-header">Fuel Price</td>
<td><sup>$</sup><?php echo $phones_retail; ?></td>
</tr>
<tr>
<td class="left-header">2-yr Contract Price</td>
<td style="font-weight: bold; color:#1b75bb;"><sup>$</sup><?php echo $phones_contract; ?></td>
</tr>
</table>
So as you can see, I need the first column to remain unchanged and adding the data related to the product to subsequent columns.

try the below code, hope it helps you:
for($td=1;$td<=$cols;$td++){
echo "<td>row: ".$tr." column: ".$td."</td>";
}
replace the above code by below one:
for($td=1;$td<=$cols;$td++){
if($td == 1)
{
echo "<td>Static Data</td>";
}
else
{
echo "<td>row: ".$tr." column: ".$td."</td>";
}
}

PHP returns incorrect HTML code ignoring some tags

I have the below code to display content from a database. The while loop is supposed to display data in a table row. The output is different: the data from the database are displayed before the table. The while seems to run and ignore the html tags, and then run again and ignore the variables.
PHP Code:
// Instantiate database
$database = new Database();
$db = $database->getConnection();
// List transactions without bundles
$query = "SELECT * FROM stock_trx WHERE bundleId IS NULL";
$statement = $db->prepare($query);
$statement->execute();
$n = $statement->rowCount();
if($n > 0){
echo "<table>
<thead>
<tr>
<th>Select</th>
<th>Date</th>
<th>Type</th>
<th>Quantity</th>
<th>Ticker</th>
<th>Amount</th>
<th>Currency</th>
</tr>
</thead>
<tbody>";
// Retrieve table content
while($row = $statement->fetch(PDO::FETCH_ASSOC)){
// Extract row
extract($row);
echo "<tr>".$id."</tr>";
echo "<tr>".$date."</tr>";
echo "<tr>".$type."</tr>";
echo "<tr>".$qty."</tr>";
echo "<tr>".$ticker."</tr>";
echo "<tr>".$amount."</tr>";
echo "<tr>".$currency."</tr>";
}
echo "</tbody></table>";
} else {
echo "No transaction";
}
HTML output:
<html>
<body>
12020-05-13 00:00:00BUYTEST1000022020-05-19 00:00:00SELTEST1200032020-05-24 00:00:00DIVTEST250<table>

Thank you
You need rows <tr> and cells <td> inside the row:
while($row = $statement->fetch(PDO::FETCH_ASSOC)){
// Extract row
extract($row);
echo "<tr>"; // start row
echo "<td>".$id."</td>";
echo "<td>".$date."</td>";
echo "<td>".$type."</td>";
echo "<td>".$qty."</td>";
echo "<td>".$ticker."</td>";
echo "<td>".$amount."</td>";
echo "<td>".$currency."</td>";
echo "</tr>"; // end row
}
echo "</tbody></table>";
Contrary to the other answer I would either do this, since you're using double-quotes:
echo "<tr>"; // start row
echo "<td>$id</td>";
// etc...
Or combine into one, maybe even one line:
echo "
<tr>
<td>$id</td>
<td>$date</td>
<td>$type</td>
<td>$qty</td>
<td>$ticker</td>
<td>$amount</td>
<td>$currency</td>
</tr>";
While some others have mentioned that you need TD tags, I'd just like to point out some weirder PHP-type things that may or may not help you now / in the future.
Your statement can be rewritten
<?php
while($row = $statement->fetch(PDO::FETCH_ASSOC)):
// Extract row
extract($row);?>
<tr>
<td><?php echo $id; ?>?</td>
<td><?php echo $date; ?>?</td>
<td><?php echo $type; ?>?</td>
<td><?php echo $qty; ?>?</td>
<td><?php echo $ticker; ?>?</td>
<td><?php echo $amount; ?>?</td>
<td><?php echo $currency; ?>?</td>
</tr>
<?php endwhile; ?>
This uses some lesser seen formats for using HTML in PHP files, but it should work never-the-less (tested locally with the PHP 7.4 CLI). Some people prefer it to having to use echo to output all of the HTML, but you do still have to have a bunch of echo statements to print the variables.
To reiterate, there's nothing wrong with any of the other answers, I just feel that in cases like this where you are using a bunch of HTML with PHP that this sort of notation can be a bit easier to work with.
As some people replied, the below tag is missing:
<td>

Display data from SQL query in an HTML table in PHP

I retrieved a list of data from an SQL database and now I would like to display it in a neat table rather than in a list. I managed to find a way to do this (probably not very elegant, though), but the column headers seem to be offset and I have not idea how to fix this.
I'm completely new to PHP, so any hints on how to solve this will be much appreciated!
echo '<table>';
echo '<tr>';
echo '<th>';
echo '<td>Word</td>';
echo '<td>Frequency</td>';
echo '</th>';
echo '</tr>';
$response = $db->query("SELECT * FROM frequencies WHERE freq BETWEEN 900 AND 910 ORDER BY freq");
while ($row = $response->fetch())
{
echo '<tr>';
echo '<td>'.$row['word'].'</td>';
echo '<td>'.$row['freq'].'</td>';
echo '</tr>';
}
echo '</table>';
$response->closeCursor();
A <th> element is a table header element and should be used instead of <td> (table data) element in your header row - it should never be a wrapper around <td> elements.
echo '<table>';
echo '<tr>';
echo '<th>Word</th>';
echo '<th>Frequency</th>';
echo '</tr>';
I prefer combining php and html
<table >
<thead>
<tr>
<th >Word</th>
<th >Frequency</th>
</tr>
</thead>
<?php
$response = $db->query("SELECT * FROM frequencies WHERE freq
BETWEEN 900 AND 910 ORDER BY freq");
?>
<tbody>
<?php
while ( $row = $response->fetch()) {
?>
<tr>
<td><?php echo $row['word']; ?></td>
<td><?php echo $row['freq']; ?></td>
</tr>
<?php }
$response->closeCursor();
?>
</tbody>

Display a tables value when a record is not empty

I have an activity table that contain the list of activity student had joined before. So if the student is new student, there will have been no activity for that student.
<table align="center" width="1000" border="1" >
<h3>Activity List</h3>
</br>
<tr align="center" style="font-weight:bold" >
<td>ID</td>
<td>Activity</td>
<td>Sem</td>
<td>Session</td>
<td>Achievement</td>
<td>Level</td>
</tr>
<?php do { ?>
<tr align="center">
<td><?php echo $row_Recordset1['student_id']; ?></td>
<td><?php echo $row_Recordset1['activity']; ?></td>
<td><?php echo $row_Recordset1['sem']; ?></td>
<td><?php echo $row_Recordset1['session']; ?></td>
<td><?php echo $row_Recordset1['achievement']; ?></td>
<td><?php echo $row_Recordset1['level']; ?></td>
</tr>
<?php } while ($row_Recordset1 = mysql_fetch_assoc($Recordset1)); ?>
</table>
How can I make this table only show on screen if it is not empty. Btw, im using session to display the exist record.
The best way to do this would be to get your array via mysql(i)_fetch_array() of the query you have build and then to chec to see if the query has rows like:
$qry = "SELECT `this` FROM `table`"
while ($result = mysql_fetch_array($qry)) {
if (mysql_num_rows($result) > 0) {
echo "We have rows!";
}
else {
echo "Looks like we haven't got anything here!";
}
}
I hope this helps.
Might also help to look here: PHP mysql_num_rows method.
<?php if(!empty($activity))
{
your msg ..
}
else
{
}
?>
where empty() will check a given variable is empty or not
Well that's what the if statement is used for:
if(!count($activities)) {
echo "This student has no activities yet.";
} else {
//display activities
....
}

How do I make a MySQL infinite array table?

I am using this code to create an infinite table for my mysql queries:
<table cellspacing='0'> <!-- cellspacing='0' is important, must stay -->
<!-- Table Header -->
<thead>
<tr>
<th>User</th>
<th>SteamID</th>
<th>Banned by</th>
<th>Admin SteamID</th>
<th>Time Banned (min)</th>
<th>Reason</th>
</tr>
</thead>
<!-- Table Header -->
<!-- Table Body -->
<tbody>
<?php
echo '<tr>';
for($i = 0; $bans = mysqli_fetch_array($query2); $i = ($i+1)%3){
echo '<td>'.$bans['name'].'</td>';
echo '<td>'.$bans['steamid'].'</td>';
echo '<td>'.$bans['nameAdmin'].'</td>';
echo '<td>'.$bans['steamidAdmin'].'</td>';
echo '<td>'.$bans['time'].'</td>';
echo '<td>'.$bans['reason'].'</td>';
if($i == 2)
echo '</tr><tr>';
}
echo '</tr>';
?>
</tbody>
I got that code from Mysql fetch array, table results
It works fine, except it doesn't CORRECTLY go further down than 6 rows. The other rows for whatever reason are placed to the right of my last column as shown in this screenshot:
http://puu.sh/h0qZF/a12de1dd87.png
How can I fix this? Is there something wrong with my code? Why is it happening?
Well, your looping makes no sense. Using $i to inject new rows, like is done here, is not necessary; you can just loop over each row and then output it as a row:
<table>
<!-- <thead>...</thead> -->
<tbody>
<?php while ($bans = mysqli_fetch_array($query2)): ?>
<tr>
<td><?php echo $bans['name'] ?></td>
<td><?php echo $bans['steamid'] ?></td>
<td><?php echo $bans['nameAdmin'] ?></td>
<td><?php echo $bans['steamidAdmin'] ?></td>
<td><?php echo $bans['time'] ?></td>
<td><?php echo $bans['reason'] ?></td>
</tr>
<?php endwhile ?>
</tbody>
</table>
You are making two columns.
You have code that will print out the end of the table row every two sets of data:
if($i == 2)
echo '</tr><tr>';
It should just be echo '</tr><tr>';
Use a while loop as instructed here . So something like this:
$result = $conn->query($sql);
while($bans = $result->fetch_assoc()) {
echo '<td>'.$bans['name'].'</td>';
echo '<td>'.$bans['steamid'].'</td>';
echo '<td>'.$bans['nameAdmin'].'</td>';
}

PHP pagination table how to change the display to top to bottom

I am trying to create the PHP pagination table.. but in below format..
ID: data
Comments: data
Date: data
but now my table is like this:
ID Comments Date
data data data
By any chance anyone could let me know how to change it? .......my code is like this now:
<?
$connection=Mysql_connect('XX','XX','XX');
if(!$connection)
{
echo 'connection is invalid';
}
else
{
Mysql_select_db('XX',$connection);
}
//check if the starting row variable was passed in the URL or not
if (!isset($_GET['startrow']) or !is_numeric($_GET['startrow'])) {
//we give the value of the starting row to 0 because nothing was found in URL
$startrow = 0;
//otherwise we take the value from the URL
} else {
$startrow = (int)$_GET['startrow'];
}
//this part goes after the checking of the $_GET var
$fetch = mysql_query("SELECT * FROM products LIMIT $startrow, 10")or
die(mysql_error());
$num=Mysql_num_rows($fetch);
if($num>0)
{
echo "<table border=0 >";
echo "<tr><td>ID</td><td>Drug</td><td>quantity</td></tr>";
for($i=0;$i<$num;$i++)
{
$row=mysql_fetch_row($fetch);
echo "<tr>";
echo"<td>$row[1]</td>";
echo"<td>$row[2]</td>";
echo"<td>$row[3]</td>";
echo"<td >$row[5]</td>";
echo"</tr>";
}//for
echo"</table>";
}
//now this is the link..
echo 'Next';
$prev = $startrow - 10;
//only print a "Previous" link if a "Next" was clicked
if ($prev >= 0)
echo 'Previous';
?></td>
<td width="331"> </td>
</tr>
</table></td>
</tr>
</table>
</td>
</tr>
<?php
include("footer.php");
?>
sorry just figure out now..
$row=mysql_fetch_row($fetch);
echo "<tr>";
echo"<td>ID:$row[1]</td>";
echo "</tr>";
echo "<tr>";
echo"<td>Drug:$row[2]</td>"; echo "</tr>"; echo "<tr>";
echo"<td>QTY:$row[3]</td>"; echo "</tr>"; echo "<tr>";
echo"<td >Date:$row[5]</td>"
;echo "</tr>";
echo"</tr>"; echo"<tr height ='20'>";echo"</tr>";
echo"<tr >";echo"</tr>";echo"<tr >";echo"</tr>";
}//for
echo"</table>";
}
Oh, I got it now !
That you can achieve below way:
<table cellpadding="0" cellspacing="0">
<tr>
<th>ID</th>
<th>Comments</th>
<th>Date</th>
</tr>
<?php
if(mysql_num_rows($recordsets) > 0){
foreach ($recordsets as $recordset):
?>
<tr>
<td><?php echo $recordset['id']); ?></td>
<td><?php echo $recordset['comments']); ?></td>
<td><?php echo $recordset['date']); ?></td>
</tr>
<?php
endforeach;
} else {
?>
<tr>
<td colspan="3">No records found !</td>
</tr>
<?php
}
?>
</table>
Here, first row will be your table records header information and then loop through your records result sets.
Hope it helps you !
