I am trying to make a leaderboard and sort my data by kills, but when I try to make it so it only grabs name, kill, death it doesnt grab anything but when I have it grab it all it works. Anyone know why? Code is below please assist.
<?php
$query = $koneksi->prepare("SELECT * from `player`");
$query->execute();
if($query->rowCount() == 0)
I am grabbing my mysql data here, if I change the * to the data I need no data is displayed.
echo "<tr><td colspan='6'><small>There's no player on ban list</small></td></tr>";
}
while($data = $query->fetch())
{
echo "<tr><td>".$data['name']."</td>";
echo "<td>".$data['kill']."</td>";
echo "<td>".$data['death']."</td>";
$kd = $data['kill'] / $data['death'];
echo "<td>".$kd."</td></tr>";
}
?>
Is it something to do with this or is something wrong? I am really confused.
Here you have to use bind_result() and in that you have to pass the number of parameters which is equal to your number of field from your player table.
Because here you are fetching data using select * query.

I'm learning this new langage PHP in order to develop modules from this software : Dolibarr
It's the first time I'm using PHP and I don't overcome to display query result in my view.
I would like to know if I wrote something wrong in my script because I don't understand all up to now. I would like to display the number of users in my software. I have to query my llx_user table and display the result in my array.
This is the part of my code :
/*
* View
*/
//Display number of users
$sql = "SELECT COUNT(u.rowid) as total";
$sql.= " FROM ".MAIN_DB_PREFIX."user as u";
$result = $db->query($sql);
print '<table class="noborder" width="100%">';
print '<tr class="liste_titre"><th colspan="2">'.$langs->trans("Statistics").'</th></tr>';
if (! empty($conf->user->enabled))
{
$statUsers = '<tr class="oddeven">';
$statUsers.= '<td>'.$langs->trans("Number of Users").'</td><td align="right">'.round($result).'</td>';
$statUsers.= "</tr>";
}
$total=0;
if ($entity == '0')
{
print $statUsers;
$total=round($result);
}
print '<tr class="liste_total"><td>'.$langs->trans("Total").'</td><td align="right">';
print $total;
print '</td></tr>';
print '</table>';
print '</div></div></div>';
llxFooter();
$db->close();
As I said, it's the first time I'm handling php file and I began to learn php 3 hours ago.
This is what I got :
If I comment like this :
$total=0;
//if ($entity == '0')
//{
print $statUsers;
$total=round($result);
//}
I'm getting this :
But I have 2 users in my table :
Thank you if you could help me
You're doing a good job for that you just started with PHP. Anyway, there's a little mistake in your code.
You actually query the database, but you don't fetch the result.
You have to do the following after your query:
$row = $result->fetch_row();
print $row[0]; // $row[0] will contain the value you're looking for
Also it seems that your $entity is not equal to 0. I don't see you initializing this variable anywhere, are you sure you have defined it? May you want to show us some mor of your code..
I've written a PHP script that can populate a table in a particular way so that multiple events (or no events) can be put in one square in an HTML - similar to the layout a calendar would have. But, there's a problem, the while statement I created to fill in squares in the table when there is no data doesn't detect when there is data, and fills the entire table with empty squares. This is what the output looks like (The page is styled using Bootstrap 3). From the mysql data I have provided, these events should be in the square at {Period 1, Monday}.
Here is my data in a mysql database; mysql data
Here is a snippet of the part of the page related to this table;
<?php
$query = "SELECT * FROM configtimetabletwo WHERE term = ".$term." AND week = ".$week." ORDER BY period, day LIMIT 100;";
$results = mysqli_query($conn, $query);
$pp=1; //The current y value of the table
$pd=0; //The current x value of the table
echo '<tr><td>';
while($row = mysqli_fetch_row($results)) {
while((pd!=$row[3] or $pp!=$row[4]) and $pp<6){ //This while statement fills in empty squares and numbers each row.
if($pd==0) {
echo $pp."</td><td>";
$pd++;
}
elseif($pd<5){
echo "</td><td>";
$pd++;
}
else {
echo "</td></tr><tr><td>";
$pd=0;
$pp++;
}
}
echo '<a href="?edit='.$row[0].'" class="label label-default">';
echo $row[5].' '.$row[6].' - '.$row[7]."</a><br>";
}
echo "</td></tr></table>"
?>
I haven't been able to figure out why this happens so far, thanks in advance to anyone who has any idea what's going on.
In the comments below my question, pavlovich pointed out the error. In this case, it was simply an issue of forgetting to use a $ to reference a variable. It would seem that this doesn't throw an error in a while statement like it would elsewhere.
I have a submit form that displays into a list format and I'm wondering what I can do to make it so that the list only displays a certain number of the most current submitted info. I'm testing it and currently the list is on a page and just displays 50+ submissions stretching out the page very long.
<?php
$query='select * from article order by `article`.`time` DESC';
$result=mysql_query($query);
echo '<table width="600px">';
while($row = mysql_fetch_array($result))
{
echo "<td><a href='".$row['url']."'>".$row['title']."</a></td> <td>".$row['description']."</td><td>".$row['type']."</td></tr>";
}
echo '<table>';
?>
Welcome to SO! Modify your sql statement as follows:
$query='SELECT * FROM article ORDER BY `article`.`time` DESC LIMIT 10';
Change 10 to however many entries should be displayed.
Even though you only should select the data you need, you might want to take a look at a for-loop, which is useful if you know how many times you want to run something. You might end up with a loop which looks like this:
for($i = 0; $i < 10 && $row = mysql_fetch_array($result); $i++) {
echo "<td><a href='".$row['url']."'>".$row['title']."</a></td> <td>".$row['description']."</td><td>".$row['type']."</td></tr>";
}
This code runs 10 times IF you have enough data.
I'm trying out my hand at php at the moment - I'm very new to it!
I was wondering how you would go about selecting all items from a mySQL table (Using a SELECT * FROM .... query) to put all data into an array but then not displaying the data in a table form. Instead, using the extracted data in different areas of a web page.
For example:
I would like the name, DOB and favorite fruit to appear in one area where there is already say 'SAINSBURYS' section hardcoded into the page. Then further down the next row that is applicable to 'ASDA' to appear below that.
I searched both here and google and cant seem to find an answer to my strange questions! Would this involve running the query multiple times filtering out the sainsburies data and the asda data where ever I wanted to place the relevant
echo $row['name']." ";
echo $row['DOB']." "; etc etc
next to where it should go?
I have got php to include data into an array (I think?!)
$query = "SELECT * FROM people";
$result = mysql_query($query) or die(mysql_error());
$row = mysql_fetch_array($result) or die(mysql_error());
while($row = mysql_fetch_assoc($result))
{
echo $row['name']." ";
echo $row['DOB']." ";
echo $row['Fruit']." ";
}
?>
Just place this (or whatever your trying to display):
echo $row['name']." ";
Anywhere you want the info to appear. You can place it within HTML if you want, just open new php tags.
<h1>This is a the name <?php echo $row['name']." ";?></h1>
If you want to access your data later outside the while-loop, you have to store it elsewhere.
You could for example create a class + array and store the data in there.
class User {
public $name, $DOB, $Fruit;
}
$users = new array();
$query = "SELECT * FROM people";
$result = mysql_query($query) or die(mysql_error());
while($row = mysql_fetch_array($result)) {
$user = new User;
$user->name = $row["name"];
$user->DOB = $row["DOB"];
$user->Fruit = $row["Fruit"];
$users[$row["name"]] = $user;
}
Now you can access the user-data this way:
$users["USERNAME"]->name
$users["USERNAME"]->DOB
$users["USERNAME"]->Fruit
$sql = "SELECT messages.text, users.name FROM messages INNER JOIN users ON messages.user_id=users.id ORDER BY messages.ms_id DESC LIMIT 10";
$result = mysql_query($sql);
$rows = array();
while($row = mysql_fetch_array($result))
{
$rows[]=$row;
}
echo $rows[0][1].$rows[0][0];
/* for($i=0;$i<=10;$i++)
{
echo $rows[i][1].$rows[i][0];
}
*/
This script is supposed to show the last 10 messages in a chat.What I'm doing is getting the Name of the user from the users table and the text from the message table and I want to display them in my chat window.Right now I have only 4 messages recorded and don't know how this affects the whole script I should implement a check for this too, but the bigger problem is that when i use echo $rows[0][1].$rows[0][0]; the info is displayed correctly, but when I try to make a loop so I can show tha last 10 (I tried the commented one) then nothing is displayed.I thought at least when I use this loop I'll see the 4 recorded messages but what really happen is a blank window.Obvously I have the info recorded in $rows[] and can echo it, but don't understand why this loop don't work at all.I'll appreciate if someone can help me with this and with the check if the messages are less then 10.
Thanks.
Leron
P.S
Here is the edited script, thanks to all of you, I need the array because otherwise the most recent message is shown at the top which is not an opiton when I use it for diplaying chat masseges.
for($i=10;$i>=0;$i--)
{
if($rows[$i][1]!="" || $rows[$i][0]!="")
{
echo $rows[$i][1].' : '.$rows[$i][0];
echo "</br>";
}
}
Your FOR loop was running 11 times even if only 10 records. The second clause should be a < instead of <=. Plus the $ was missing on the i variable.
For example sake, you don't really need to make an array from the rows, and you can refer to the fields by name:
while($row = mysql_fetch_array($result))
{
echo $row['name'] . ' says: ' . $row['message'] . '<BR>';
}
why not just do
while($row = mysql_fetch_array($result))
{
echo $row[1]." ".$row[0];
}
Your query, auto limits it to the last 10, this will then show anything from 0 to 10 which get returned.
PS I added a space between username and message for readability
You need $ symbols on your i variable:
for($i=0;$i<10;$i++)
{
echo $rows[$i][1].$rows[$i][0];
}
A more robust solution would be like this:
$sql = "SELECT messages.text, users.name FROM messages INNER JOIN users ON messages.user_id=users.id ORDER BY messages.ms_id DESC LIMIT 10";
$result = mysql_query($sql);
while($row = mysql_fetch_array($result))
{
echo $row[1].$row[0];
}
