PHP - Pulling Data From 2 Separate Tables

I am trying to make a filter to show posts from mutual friends between you and the persons profile you're on, I have somewhat of an idea on how to write the mysql query (it needs to be just one query, not two(which would be the easy way of doing it)).

the "friends" table has:
"friend_1" and "friend_2"

and the "posts" table:
"to_id" and "from_id"

The PHP variables would be:
"$session" and "$id"
id would be the users Id of the profile you're on.

Thanks, any help would be appreciated.

Code: [Select]
id: 20 Reason: this is a test
id: 21 Reason: Tests
id: 22 Reason: Lolcatz
id: Reason:
id: Reason:
id: Reason:
id: Reason:
id: Reason:
id: Reason:
id: Reason:
id: Reason:

id: Reason:
id: Reason:
id: Reason:
id: Reason:
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

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?

/*print_r($arrayName);

an example XML file would be:

</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:

Thanx in advance

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

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");

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);

what is the best way yo do this?

Hello:

I have a DB table with this structu

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:

          <select name='category_name'>
<option></option>

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

Thanks!

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?


?>


Thanks!!

Hi,

having problems getting checkboxes to display all reuslts when a user selects more than one check box say in the category section and one in the location section - see page http://www.partyco.co.uk/event-and-party-venues/ - submit to see reults page:

I managed to get it to display reults if the user only seletc either a right or left column option OR one of each - BUT not when thet select multiple categories and one location - and ideas how to do this ? putting it into an array perhaps - but how - new to some of this....

Any help appreciated!

MOD EDIT: [code] . . . [/code] BBCode tags added.

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!
