PHP - Pulling Data From Multiple Tables

This topic has been moved to MySQL Help.

http://www.phpfreaks.com/forums/index.php?topic=305902.0

FOr some reason i cant pull data from an XML file to insert into the database, it works without error just adds a blank value in the database?

i have this code at the moment, i guess arrayValue[71] is the value i need to pull and add to the "TABLE2" table, but when i run the script it just adds a blank value in the database?


<?php
include "connect.php";

//Price check Isle 9001! Query EVE-Central API. Example XML file is: http://api.eve-central.com/api/marketstat?typeid=35&regionlimit=10000002
$queryItemList = mysql_query("SELECT * FROM TABLE2;") or die(mysql_error());
$rowCount = mysql_num_rows($queryItemList);
$s=0;
$typeArray = array();
$region = "regionlimit=10000002";
while($s<$rowCount){

$typeID = mysql_result($queryItemList,$s,"typeID");

echo $typeID."<br />";

//echo "start<br />";

$reader = new XMLReader();

//echo "initialized XMLReader<br />";

$url = "http://api.eve-central.com/api/marketstat?typeid=".$typeID;

echo $url.$region."<br />";

$reader->open($url.'&'.$region);

$t=0;

$arrayName = array();

$arrayValue

 = array();

while ($reader->read()) {

//echo $reader->name;

$name = $reader->name;

$arrayName[$t] = $name;

if ($reader->hasValue) {

//echo ": " . $reader->value."<br />";

$value = $reader->value;

$arrayValue[$t] = $value;

}

$t++;

}

echo $arrayValue[71];

$import="UPDATE TABLE2 SET marketPrice='$arrayValue[71]' WHERE typeID='$typeID';";

mysql_query($import) or die(mysql_error());

$s++;;
}
print_r($typeArray);

/*print_r($arrayName);
echo "<br />";
echo "<br />";
echo "<br />";
print_r($arrayValue);*/

?>


an example XML file would be:
Code: [Select]
<!--

<!-- This is the new API :-) -->

</marketstat>
</evec_api>

im looking at pulling the following value from the <sell> section:
Code: [Select]
<median>152500000.00</median>
i am guessing the above should be arrayValue[71] but for some reason its not picking it up.

any help on this would be greatly appreciated as im lost in this script.

I am pulling records from a mysql db.   

Example Output:

Team A=  Our Team
Team b = An opponent team
Team A score = 7
Team B score = 8

Team A = Our Team
Team b = Another Opponent
Team A score = 3
Team B score = 1


What I need now is to add ONE more output, which is whether this is a "WIN" or a "LOSS".

Should I add a field into the table that calc's this?    If so, how?   Please be specific.

Or, should I use php to compare Team A score vs Team B score PER every record and then insert this new variable into the output.    If so, how do I create a new variable value for every single output in the table?


I know ultimately that this is a IF THEN type of calc, but can't quite figure out how specifically.   

Please be specific.

Thanks

Good evening,

This has been bugging me for 24 hours now. I have created 2 web applications. The first one is the dummy, and the second one is the final. Basically, this two web applications does the same, just a few modifications made on the final one. I have a process of pulling out of information from the database should the user would want to modify a field. I have a problem though, the dummy one works perfectly, but the new one don't. In fact, if I use the dummy php file together with the new files, the dummy won't be working. But if I use it together with the old files, it works perfectly fine.

This is the error I am getting:

Your quick response is well appreciated. Thank you very much

id: 36 Reason: Test
As you can see on the 2nd code box there are id's 20,21,22 and 36 in the database the rest are not active in the database.

i am using using Code: [Select]
for to pull out the id that starts with the lowest value in the database, and only have it run until it gets to the maximum value.
Code: [Select]
for ($id=$set_min; $set_max<=7; $id++)
{
                // $id=$set_min is pulling the smallest value and $set_max is pulling the maximum value so it stops  after it gets to 36
$query=mysql_query("SELECT * FROM posted WHERE id = $id");
$query_row=mysql_fetch_array($query);

$reason = $query_row[reason];
$pulled_id = $query_row[id];
$pulled_pic22 = $query_row[picture];
$href_pull = "<a href=" . "search.php?id=" . "$id" .">";

echo "<td>" . $href_pull . "<img src=$pulled_pic22 height=200 width=150 />" . "</td>";
}

how would i make it so i do not pull the values 23-35 which are not in the active database.

Example: http://dev.hackmuch.com/of-the-day/search.php?id=36

Hey, I was wondering if there is a way to pull multiple rows at once using a list of unique identifiers. For example, I want to pull the rows with the IDs of 4,13,91 and 252

I know the WHERE part of this query is incorrect, but I'm putting it to hopefully help you guys understand what I'm looking for.

$result = mysql_query("SELECT * FROM $table WHERE id='4' OR '13' OR '91' OR '252'");
while($row = mysql_fetch_array($result))
{
echo($row['name']);
}


Or is the best way simply to do it one query at a time without a while statement? There could be as many as a few dozen records being pulled per page.

Hello,   I'm not sure if I'm allowed to post the code, as I didn't write it. But, if you could offer some ideas on where I'm going wrong, I'd be very appreciative!   I basically have a feature on my homepage that displays "Hello _username_!" upon login, but the username is missing. So, I'm presuming that the functionality for pulling the username from the table is somehow failing.   Any ideas?   Thanks   Daisy

index.php?page=1 that link style but there is not hard files it is all to be stored in the DB

here is what i have got so far

Code: [Select]
<?

$result = mysql_query("SELECT * FROM page") or die(mysql_error());
$row = mysql_fetch_array( $result );

if(isset($_GET['page'])) {
echo $row['text'];
} else {
$result = mysql_query("SELECT * FROM page
 WHERE id='1'") or die(mysql_error());
$row = mysql_fetch_array( $result );
echo $row['text'];
}
?>
but always shows page ID 1 (home page) so i no i am missing something just not sure what hehe

DB structu
Code: [Select]
menu
----id (auto increase)
----name (home, about etc)
----id2 (page weight)
pages
----id (auto increase)
----name (page name home, about etc)
----text (page text)


link structure from the menu

Code: [Select]
<?

$result = mysql_query("SELECT * FROM menu ORDER BY id2") or die(mysql_error()); 


?>
<table>
<?
while($row = mysql_fetch_array( $result )) { ?>

<tr><td>
<a href="index.php?page=<? echo $row['id'];?>"><? echo $row['name']; ?></a>
</td></tr> <?
}
?>
</table>


dont think i have missed any info that i have on file but not sure why it will not link so thought of you guys hehe

Thanx in advance

Newbie here, I am actually a math teacher working on creating a simulated store front for my students where they keep up with inventory, budgeting etc.

Everyday my students will have to look at how much product is in stock, how much product was sold, and then input how much should be ordered for the next day.

I am working on an answer key that will be used to validate students input but the 'quantity' and 'sold' fields will be relative to the most recent post. Right now the code below pulls all the rows under 'quantity', but I need it to only pull the most recent post.

I have done my best to search the forum and try to find how to do this, but admittedly I am not even really sure what to be searching for. Any help would be great.



Code: [Select]
<?php
$con = mysql_connect("localhost","user","pass");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("myDatabase", $con);

$result = mysql_query("SELECT * FROM myTable");

while($row = mysql_fetch_array($result))
  {
 $quantity = $row['quantity'];
 $sold = $row['numbersold'];
 $needed = $row['remaining'];
 echo $needed-($quantity-$sold);
  }

mysql_close($con);
?>

Okay, so I'm trying to run a query to pull the information from a specific item that they click on in order to edit it.

When I run an echo $query, though, it shows the field names rather than the information from the table.

How can I make it so that it pulls the information rather than the field names?

Here's what I have...


<?php
include("lib.php");
define("PAGENAME", "Edit Equipment");

if ($player->access < 100)

$msg1 = "<font color=\"red\">"; //name error?
$error = 0;

$query = $db->execute("SELECT * FROM items WHERE id=?", array($_POST['id']));

echo "$id";

$result = mysql_query($query);

echo "$query";

$data = mysql_fetch_assoc($result); 

$msg1 .= "</font>"; //name error?


?>

Hello:

I have a DB table with this structu
Code: [Select]
CREATE TABLE `gallery_category` (
  `category_id` bigint(20) unsigned NOT NULL auto_increment,
  `category_name` varchar(50) NOT NULL default '0',
  PRIMARY KEY  (`category_id`),
  KEY `category_id` (`category_id`)
) ENGINE=MyISAM AUTO_INCREMENT=2 DEFAULT CHARSET=latin1 AUTO_INCREMENT=2 ;

What I am trying to do id pull this data into my "Edit Product" page and populate a SELECT menu with it.

I want the user to be able to re-assign a product to a new category if they chose to do so.

I want to add the data (and update the DB) to this area:
Code: [Select]
         <div style="float: left; width: 550px;">
          <select name='category_name'>
<option></option>
</select>

         </div>

This is the full page code that allows users to update product info:
Code: [Select]

How can I do this? I'm stumped ...

Thanks!

what is the best way yo do this?

Code: [Select]
<b><font color=green>Get me out please </font> . </b>
thanks in  advance

Hey!

I have it so users can submit info to my site. They have to check some check boxes and radio buttons. I want them to be able to edit this information, so I want to have the data pulled from the MySQL database and have the correct radio button selected (and the text bolded). So I'm thinking some sort of array to check for each value in the database... but I don't really know.

There are a few groups of radio boxes and check boxes but here is an example of one.

Code: [Select]
<input type="radio" name="stage" value="Stage 1" /> Stage 1
 <input type="radio" name="stage" value="Stage 2" /> Stage 2
 <input type="radio" name="stage" value="Stage 3" /> Stage 3

The information is pulled from the database like this:

Code: [Select]
$res=mysql_query("SELECT * FROM ACTIVE WHERE INDEX_ID=$id");
if(mysql_num_rows($res)==0) echo "There is no data in the table <br /> <br />";
else
{
 for($i=0;$i<mysql_num_rows($res);$i++)
 {
  $row=mysql_fetch_assoc($res);
 }
}

So when I pull information (lets say I want to echo it) it'd look like this:

Code: [Select]
$row[STAGE]
The value for the stage selection can only be Stage 1, Stage 2 or Stage 3 so I need it to be selected when the page loads.

Thanks!
