But the data from "product" doesn't show. So my point is: Can someone help me get the products data from the DB, thanks in advance

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 "</tr>";
echo"</tr>"; echo"<tr height ='20'>";echo"</tr>";
echo"<tr >";echo"</tr>";echo"<tr >";echo"</tr>";
}//for

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 !
I'm trying to display my products from the database. I'm trying to split it using the if 4%=0, but I can't get it to display 4 items in a row.
Here is my codes:
<table>
<tr>
<?php
include "connect_to_mysql.php";
$split = 0;
$display_all = mysql_query("SELECT * FROM products
ORDER BY FIELD(category, 'ipad','iphone','others')");
while($row=mysql_fetch_array($display_all)) {
$id = $row['id'];
$product_code = $row['product_code'];
$title = $row['title'];
$price = $row['price'];
$split++;
if ($split%4==0){
echo '</tr><tr>';
}
?>
<td>
<table class="normal_text" align="center">
<tr>
<td><a href="product.php?product_id=<?php echo $id?>">
<img width="200px" height="133px" src="products/<?php echo $product_code?>.jpg" />
</a></td>
</tr>
<tr>
<td align="center" style="font-weight:bold"><?php echo $title;?></td>
</tr>
<tr>
<td align="center">$<?php echo $price;?></td>
</tr>
</table>
</td>
<?php
}
?>
</tr>
</table>
You've got the PHP logic before, rather than inside your HTML table output.
Try reorganizing like this:
<?php
include "connect_to_mysql.php";
$split = 0;
$display_all = mysql_query("SELECT * FROM products
ORDER BY FIELD(category, 'ipad','iphone','others')");
?>
<table class="normal_text" align="center">
<tr>
<?php
while($row=mysql_fetch_array($display_all)) {
$id = $row['id'];
$product_code = $row['product_code'];
$title = $row['title'];
$price = $row['price'];
// output product details -- note use of quotes to include PHP vars
$rowHTML = "<td><a href='product.php?product_id=$id'>";
$rowHTML .= "<img width='200px' height='133px' src='products/$product_code.jpg' />";
$rowHTML .= "</a><br/>";
$rowHTML .= "<strong>$title</strong>";
$rowHTML .= "$price</td>";
echo $rowHTML;
$split++;
if ($split%4==0){
echo '</tr><tr>';
}
}
?>
</tr>
</table>
while($row=mysql_fetch_assoc($display_all)) {
$id = $row['id'];
$product_code = $row['product_code'];
$title = $row['title'];
$price = $row['price'];
if ($split % 4 === 0) echo "\n<tr>";
?>
// ONLY <td> CODE </td> here. NO <tr> and NO </table>
<?php
if ($split % 4 === 3) echo "</tr>";
$split++;
}
?>
You are starting and ending at same time and then putting table for each.
You want to start <tr> when %4==0 and end </tr> when %4==3.
Rather than use modulus (%), just add a second variable called $cols, assign it to the amount of columns you want, and compare it. For example:
$rows = 1;
$cols = 4;
$display_all = mysql_query("SELECT * FROM products ORDER BY FIELD(category, 'ipad','iphone','others')");
while($row=mysql_fetch_array($display_all)) {
$id = $row['id'];
$product_code = $row['product_code'];
$title = $row['title'];
$price = $row['price'];
$split++;
if ($rows==$cols){
echo '</tr><tr>';
$rows = 1;
}
I want to have the ability to show all the entries in a database table and by each one give the user the ability to delete specific ones.
I am currently using a for each loop that loops through the database showcasing each entry.
$result = mysql_query("SELECT * FROM KeepScores");
$fields_num = mysql_num_fields($result);
echo "<table><tr>";
// printing table headers
echo "<td>Recent Posts</td>";
echo "</tr>\n";
// printing table rows
while($row = mysql_fetch_row($result))
{
echo "<tr>";
// $row is array... foreach( .. ) puts every element
// of $row to $cell variable
foreach($row as $cell)
echo "<td>$cell</td>";
echo "</tr>\n";
}
How would to add a delete button that appears by each one and removes the entry from the database table?
You can do it with forms:
//main.php
<?php $result = mysql_query("SELECT * FROM KeepScores"); ?>
<table>
<tr>
<td>Recent Posts</td>
</tr>
<?php while($row = mysql_fetch_array($result)) : ?>
<tr>
<td><?php echo $row['field1']; ?></td>
<td><?php echo $row['field2']; ?></td>
<!-- and so on -->
<td>
<form action="delete.php" method="post">
<input type="hidden" name="delete_id" value="<?php echo $row['id']; ?>" />
<input type="submit" value="Delete" />
</form>
</td>
</tr>
<?php endwhile; ?>
</table>
//delete.php:
<?php
if(isset($_POST['delete_id'] && !empty($_POST['delete_id']))) {
$delete_id = mysql_real_escape_string($_POST['delete_id']);
mysql_query("DELETE FROM KeepScores WHERE `id`=".$delete_id);
header('Location: main.php');
}
Or you can do it with jQuery and AJAX:
//main.php
<?php $result = mysql_query("SELECT * FROM KeepScores"); ?>
<table>
<tr>
<td>Recent Posts</td>
</tr>
<?php while($row = mysql_fetch_array($result)) : ?>
<tr id="<?php echo $row['id']; ?>">
<td><?php echo $row['field1']; ?></td>
<td><?php echo $row['field2']; ?></td>
<!-- and so on -->
<td>
<button class="del_btn" rel="<?php echo $row['id']; ?>">Delete</button>
</td>
</tr>
<?php endwhile; ?>
</table>
<script>
$(document).ready(function(){
$('.del_btn').click(function(){
var del_id = $(this).attr('rel');
$.post('delete.php', {delete_id:del_id}, function(data) {
if(data == 'true') {
$('#'+del_id).remove();
} else {
alert('Could not delete!');
}
});
});
});
</script>
//delete.php
<?php
if(isset($_POST['delete_id'] && !empty($_POST['delete_id']))) {
$delete_id = mysql_real_escape_string($_POST['delete_id']);
$result = mysql_query("DELETE FROM KeepScores WHERE `id`=".$delete_id);
if($result !== false) {
echo 'true';
}
}
It's all untested and sure needs some adjustment for your specific project, but I think you get the idea and I hope it helps.
Next time, please post your schema if you ask stuff about database.
I thought I would improve on this a little bit by wrapping the delete post in a class and function. I was having the same problem. and this worked great for me. Thanks again # Quasdunk
<?php
// Class to hold the remove post function
class someClass{
//Function for removing the post
function removePost(){
if(isset($_POST['delete_id']) && (!empty($_POST['delete_id']))) {
$delete_id = mysql_real_escape_string($_POST['delete_id']);
$result = mysql_query("DELETE FROM post WHERE post_id='".$delete_id."' AND post_member='" . $_SESSION['SESS_USER'] . "'");
if($result !== false) {
echo 'true';
}
}
}
}
if(isset($_SESSION['SESS_MEMBER_ID'])){
$member = $_SESSION['SESS_USER'];
$res = mysql_query("SELECT * FROM post WHERE post_member='$member' ORDER BY timestamp DESC") or die(mysql_error());
$i = new someClass;
while($row = mysql_fetch_array($res)){
echo '<div style="width:100%;margin:0 auto;border-top:thin solid #000;">';
echo '<div style="width:600px;margin:0 auto;padding:20px;">';
echo $row['post_text'] . '<br>';
$postID = $row['post_id'];

Produce a key to each table, using jquery,then link it to a php file which an accept the key and delete from the specific table (which also can be passed through jquery)
