I want to make a Navigation with 2 levels.
My Code so far
<?php
$sql = ("SELECT name, id, pid FROM tl_table WHERE pid='' ORDER BY name");
$result = mysql_query($sql);
$list = array();
while ($row = mysql_fetch_assoc($result)) {
$list[] = $row;
}
foreach ($list as $kat) {
echo '<li>' . $kat['name'] . '</li>';
}
?>
Nested Sets are at the moment too tricky for me.
I want at the end this.
<li>$kat['name']
<li>$kat['name'] from PID</li>
</li>
MySQL:

No I want to get the things our of the MySQL DB see the image Link.
MySQL:
id—–pid——name
1——0——–name1
2——0——–name2
3——0——–name3
4——3——–name3.1
5——3——–name3.2
<?php
$sql = ("SELECT name, id, pid FROM tl_table WHERE pid='' ORDER BY name");
$result = mysql_query($sql);
$list = array();
while ($row = mysql_fetch_assoc($result)) {
$list[$row['id']] = $row;
$sql = ("SELECT name, id, pid FROM tl_table WHERE pid='".$row['id']."' ORDER BY name");
$res = mysql_query($sql);
while($rw = mysql_fetch_assoc($res)){
$list[$row['id']]['sub'][] = $rw;
}
}
echo "<pre>";
print_r($list);
?>

This is the entire code the error must be in query 3 or 4. As you can see query 3 just gets info to build query 4 which should return the results.
I've got query 1 & 2 working ok which have the correct data showing.
<?php
session_start();
//printf('<pre>%s</pre>', print_r($_SESSION, true));
require('includes/config.inc.php');
require('includes/session.php');
//WORKING
DB_Connect();
$query = "SELECT * FROM food_delivery_orders_items WHERE food_delivery_orders_items.type = 'product' AND food_delivery_orders_items.order_id=".$_SESSION['pdf_quote']['id']."";
$result = mysql_query( $query) or die(mysql_error());
while($row = mysql_fetch_array($result))
{
$hash = $row['hash'];
$foreignid = $row['foreign_id'];
$qty = $row['cnt'];
}
$query2 = "SELECT * FROM food_delivery_products WHERE food_delivery_products.id = ".$foreignid."";
$result2 = mysql_query( $query2) or die(mysql_error());
while($row = mysql_fetch_array($result2))
{
$name = $row['name'];
$description = $row['description'];
}
//---------------------------------------------------------------------------------------------------------------
$query3 = "SELECT * FROM food_delivery_orders_items WHERE food_delivery_orders_items.type = 'extra' AND food_delivery_orders_items.order_id=".$_SESSION['pdf_quote']['id']."";
$result3 = mysql_query( $query3)or die(mysql_error()) ;
while($row = mysql_fetch_array($result3))
{
$foreignidextra = $row['foreign_id'];
$qtyextra = $row['cnt'];
}
$query4 = "SELECT * FROM food_delivery_extras WHERE food_delivery_extras.id = ".$foreignidextra."";
$result4 = mysql_query( $query4) or die(mysql_error());
while($row = mysql_fetch_array($result4))
{
$nameextra = $row['name'];
}
echo $nameextra;
echo $qtyextra;
DB_Disconnect();
//$products = implode(", ",$_SESSION['pdf_quote']['product_arr']);;
//print $products
?>
print $row; is only valid inside the loop if you want to print all of them. Otherwise it will print only the last $row. Make it
while($row = mysql_fetch_array($result3))
{
$foreignidextra = $row['foreign_id'];
$qtyextra = $row['cnt'];
print $row;
}
its because you are printing the $row after the while loop gets executed
So it only prints the final result set
Use something like this instead:
$query3 = "SELECT * FROM food_delivery_orders_items WHERE food_delivery_orders_items.type = 'extra' AND food_delivery_orders_items.order_id=".$_SESSION['pdf_quote']['id']."";
$result3 = mysql_query( $query3) ;
while($row = mysql_fetch_array($result3))
{
$foreignidextra = $row['foreign_id'];
$qtyextra = $row['cnt'];
print_r($row);
}
you can also use the var_dump($row); instead of print_r($row);
this will output all the values stored in the $row array each time the loop iterates
I am having an issue with a while statement only returning one result. this is my first time trying to display product information from several tables and I don't know what I'm doing wrong. here is the code:
<?php
require('./includes/config.inc.php');
require(MYSQL);
$sql = sprintf("SELECT * FROM tea");
$res = mysqli_query($dbc, $sql);
if(!$res){
die('Could not complete query: '.mysqli_error($dbc));
} else {
echo 'Success!<br />';
while($row = mysqli_fetch_array($res)){
$table = $row['category'];
$inum = $row['item_number'];
echo $table.' '.$inum.'<br />';
$fetch = sprintf("SELECT sub_category, item_name, description FROM $table WHERE item_number ='$inum'");
$fetchRes = mysqli_query($dbc, $fetch);
if(!$fetchRes){
die('Could not fetch: '.mysqli_error($dbc));
} else {
while($fetchRow = mysqli_fetch_array($fetchRes)){
$subCat = $fetchRes['sub_category'];
$iNumber = $inum;
$iname = $fetchRes['item_name'];
$desc = $fetchRes['description'];
echo $id.' '.$subCat.' '.$iNumber.' '.$iname.' '.$desc.'<br />';
}
}
}
}
Inside your while loop, you should be using the $fetchRow variable as the array from which to grab columns, such as 'sub_category'.
IS
$subCat = $fetchRes['sub_category'];
$iNumber = $inum;
$iname = $fetchRes['item_name'];
$desc = $fetchRes['description'];
Needs to be: Res to Row
$subCat = $fetchRow['sub_category'];
$iNumber = $inum;
$iname = $fetchRow['item_name'];
$desc = $fetchRow['description'];
The query I have below will only show me one result even if there are multiple matching entries (completely or partially matching). How do I fix it so it will return all matching entries:
//$allowed is a variable from database.
$sql = "SELECT `users`.`full_name`, `taglines`.`name`, `users`.`user_id` FROM
`users` LEFT JOIN `taglines` ON `users`.`user_id` = `taglines`.`person_id`
WHERE ( `users`.`user_settings` = '$allowed' ) and ( `users`.`full_name`
LIKE '%$q%' ) LIMIT $startrow, 15";
$result = mysql_query($sql);
$query = mysql_query($sql) or die ("Error: ".mysql_error());
$num_rows1 = mysql_num_rows($result);
if ($result == "")
{
echo "";
}
echo "";
$rows = mysql_num_rows($result);
if($rows == 0)
{
}
elseif($rows > 0)
{
while($row = mysql_fetch_array($query))
{
$person = htmlspecialchars($row['full_name']);
}
}
}
print $person;
Because your overwriting $person on each iteration.
Hold it in a $person[] array if your expecting more then one. Then loop through it with a foreach loop when you intend to output.
Not related but your also querying twice, you only need 1 $result = mysql_query($sql);
Update (Simple Outputting Example):
<?php
$person=array();
while($row = mysql_fetch_array($query)){
$person[] = array('full_name'=>$row['full_name'],
'email'=>$row['email'],
'somthing_else1'=>$row['some_other_column']);
}
//Then when you want to output:
foreach($person as $value){
echo '<p>Name:'.htmlentities($value['full_name']).'</p>';
echo '<p>Eamil:'.htmlentities($value['email']).'</p>';
echo '<p>FooBar:'.htmlentities($value['somthing_else1']).'</p>';
}
?>
Or an alternative way to is to build your output within the loop using concatenation.
<?php
$person='';
while($row = mysql_fetch_array($query)){
$person .= '<p>Name:'.$row['full_name'].'</p>';
$person .= '<p>Email:'.$row['email'].'</p>';
}
echo $person;
?>
Or just echo it.
<?php
while($row = mysql_fetch_array($query)){
echo '<p>Name:'.$row['full_name'].'</p>';
echo '<p>Email:'.$row['email'].'</p>';
}
?>
I have a query like this:
$query = "SELECT gyms.name FROM `fighters_team` INNER JOIN gyms ON gyms.id = fighters_team.gym_id WHERE fighter_id = $fighter_id";
if ($result = $mysqli->query($query)) {
while($row = $result->fetch_assoc()) {
echo $row['name'];
echo " / ";
}
}
What comes up is: "Team 1 / Team 2 /"
What I want to do is get rid of the trailing slash on the last item. So it should just say "Team 1 / Team 2" if there are two items.
Does anyone have any idea how I could approach that?
Thanks!
$query = "SELECT gyms.name FROM `fighters_team` INNER JOIN gyms ON gyms.id = fighters_team.gym_id WHERE fighter_id = $fighter_id";
$names = array();
if ($result = $mysqli->query($query)) {
while($row = $result->fetch_assoc()) {
array_push($names, $row['name']);
}
echo implode(' / ', $names);
}
I hope this would work.
Try:
$query = "SELECT gyms.name FROM `fighters_team` INNER JOIN gyms ON gyms.id = fighters_team.gym_id WHERE fighter_id = $fighter_id";
if ($result = $mysqli->query($query)) {
while($row = $result->fetch_assoc()) {
$teams .= $row['name'].' / '.'';
echo rtrim($teams,'/ ');
}
}
Is that what you are looking for?
I'm currently adding fileID to idarray[] and then do a foreach. But in addition to fileID I also need serverID and id in the array and the foreach, how do I do this? So basically I need to find out how to add 2 more values to the array and then also use those extra values in the foreach.
$result = mysql_query("SELECT * FROM redundfiles WHERE removed=1");
while($row = mysql_fetch_array($result))
{
$idarray[] = $row['fileID'];
}
foreach ($idarray as $value)
{
$result = mysql_query("SELECT * FROM redundfiles WHERE fileID=$value AND removed=0 AND serverID=$XXXserverIDhereXXX");
while($row = mysql_fetch_array($result))
{
$sql = "DELETE FROM redundfiles WHERE id='".$XXXidhereXXX."' ";
mysql_query($sql) or die(mysql_error());
}
}
Why not just store the whole row into an array?
$rowarray[] = array();
$result = mysql_query("SELECT * FROM redundfiles WHERE removed=1");
while($row = mysql_fetch_array($result))
{
$rowarray[] = $row;
}
foreach ($rowarray as $row)
{
$fileid = $row['fileID'];
$serverid = $row['serverID'];
$result = mysql_query("SELECT * FROM redundfiles WHERE fileID=$fileid AND removed=0 AND serverID=$serverid");
while($row = mysql_fetch_array($result))
{
$sql = "DELETE FROM redundfiles WHERE id='".$XXXidhereXXX."' ";
mysql_query($sql) or die(mysql_error());
}
}
But really, your whole code piece here is a mess. You can accomplish this way more efficiently using JOINs.
